Tips for Growing Flowers 6) Water the flowers 1) The residual tea is used to water the flowers, which can not only keep the soil moisture, but also water it regularly and appropriately depending on the humidity of the flowerpot, instead of pouring it with the residual tea. 2 spoiled milk watering flowers After the spoiled milk, water is added to water the flowers, which is beneficial to the growth of flowers. But it is better to use more water to dilute it. Unfermented milk is not suitable for watering flowers, because it generates a lot of heat during fermentation and will &”;burn&”; roots (rotten roots). (3) water the flowers with cold water. Water the flowers with cold water can make the flowers and trees flourish and promote their early flowering. If it is used to water asparagus, its branches and leaves can develop horizontally and be short and dense. (4) warm water to water the flowers. It is cool in winter, so it is advisable to water the flowers with warm water. It is best to put the water indoors until it is close to room temperature. It is better if the water temperature can reach 35℃ before watering. ⑤ Wash rice and water the flowers. Water Milan and other flowers often with rice washing water, which can make them flourish and have bright colors. 6 people who love to water flowers when there is no one at home, such as visiting relatives or going out on business for ten and a half months, are not at home, and no one waters flowers. At this time, a plastic bag can be filled with water, a small hole can be punched in the bottom of the bag with a needle, and placed in a flowerpot. The small hole is attached to the soil, and the water will slowly leak out to wet the soil. The size of the hole needs to be well controlled to avoid water leakage too quickly. Or put a vessel filled with cold water next to the flowerpot, find a wide cloth strip with good water absorption, put one end in the vessel water and the other end in the flowerpot soil, so that the soil can be kept moist for at least half a month and the flowers will not die. 2. Five methods of fertilization (1) Medical stone fertilizer Sprinkle a layer of medical stone particles in the flowerpot to promote the growth of flowers and prolong the flowering period. (2) Broken eggshell fertilizer crushes eggshells and embeds them in flowerpots, which is a good fertilizer, and can make potted flowers flourish, with colorful leaves. (3) Cook a small amount of soybeans for later use. Each pot of flowers goes through three holes, and 3-5 pieces of cooked soybeans are put in, which is 2-3 cm deep, without hurting the flower roots, and the soil is covered as usual. (4) Bake and smash pig bones and fish bones that are usually discarded, and cast the basin bottom or basin surface. (5) Water the flowers with washed rice. Rice washing water contains trace elements such as nitrogen, phosphorus, potassium, etc., which is both a compound fertilizer and a mild fertilizer, without hurting flower roots, as long as the basin soil is not soaked in water. 3. Collecting organic fertilizer for potted flowers It is not suitable to use chemical fertilizer in family flower cultivation. Nitrogen, phosphorus, potassium and other main fertilizers needed to cultivate flowers can be collected in daily life. For example, moldy and inedible waste peanuts, beans, melon seeds and miscellaneous grains are all nitrogen-containing fertilizers, which can promote the vigorous growth of flowers and trees after fermentation as base fertilizer or soaking into solution as topdressing; Fishbone, broken bones, chicken feathers, eggshells, nails and hair cut by people are all rich in phosphorus. These wastes are mixed into the old culture soil, added with some water, put in plastic bags and put in the corner. After a period of decomposition, they can become excellent organic fertilizers. If these wastes are soaked into solution and topdressing, the domestic potted flowers will be bright in color and rich in fruits. In addition, fermented rice washing water, water replaced by raw bean sprouts, plant ash water, rainwater and wastewater in fish tanks all contain certain amounts of nitrogen, phosphorus and potassium, which will promote the growth and development of flowers and trees as long as they are used properly. 4. Pericarp can neutralize alkaline basin soil in the south.Some flowers are not easy to survive or bloom in potted plants in the north, which is because the alkalinity of the pot soil is too large. There are many ways to neutralize alkaline soil. In this method, the peeled apple peel and apple core are soaked in cold water, and the flowerpot is often watered with this water, which can gradually reduce the alkalinity of the pot soil and be beneficial to the growth of some plants. 5. Flower disease prevention In early spring, all kinds of flowers will enter a vigorous growing season. At this time, 1% Bordeaux mixture can be sprayed on the leaves and back of leaves for 1-3 times to prevent diseases. The preparation method of 1% Bordeaux mixture is: 1 gram of copper sulfate, crushed and dissolved in 50 ml of heated water; Then use 1 gram of quicklime, pulverize it with a few drops of water, then add 50 ml of water and filter off the residue; Pour these two solutions into the same container at the same time and mix well, and finally get the transparent Bordeaux solution with blue sky. 6. Six methods to kill insects and ants in flowerpots (1) When there are small flying insects in flowerpots, you can use three or four cotton sticks (cotton sticks) to fully dip dichlorvos, so as not to drip down, and then insert the handle end into the pot soil around the plant to kill the flying insects. (2) Washing powder: Dissolve one tablespoon of washing powder in 4 liters of water and spray flowers and leaves every two weeks, which can completely eliminate white flies and bacteria. (3) Milk: Mix 4 cups of flour and half a cup of milk into 20 liters of water, stir, filter with gauze and spray on the flowers and leaves, which can kill the walls and them. (4) Beer: Pour the beer into a shallow pot under the soil of the flowerpot, and the snail will be drowned if it climbs in. (5) Garlic: Mash a garlic head, mix it with a spoonful of pepper into half a liter of water, and spray it on the flower leaves one hour later to prevent the invasion of rats. (6) When ants appear in the flowerpot, the cigarette butts and cut tobacco can be soaked in hot water for one or two days. When the water turns dark brown, part of the water is sprinkled on the flower stems and leaves, and the rest is diluted and poured into the flowerpot to eliminate the ants. 7. Three methods of keeping flowers fresh ① rosa multiflora used fire moxibustion at his cut and then inserted it into the bottle. Autumn chrysanthemum is coated with a little mint crystal at its cut. Chrysanthemum in the clear water for raising chrysanthemums, adding a small amount of urea or soil leaching solution (solution obtained by mixing fertile soil with water and filtering), can make chrysanthemum in bottles wither for up to 30 days, which can be extended by more than 10 days compared with ordinary clear water. White orchids are wrapped in wet cloth at night and uncovered during the day, which can delay the fading time of flowers by 2-3 days. Hibiscus flowers are inserted into hot water for a minute or two, and then into cold water. Dahlia scissors are immersed in hot water for a while, and then inserted into cold water. Peony flowers are soaked in hot water first, and then inserted into cold water. Camellia is inserted into light salt water. Lilies are inserted into sugar water. Gardenia flowers add 1-2 drops of fresh meat juice to water. Narcissus is planted in one thousandth of light salt water. Lotus plugs the pores with mud and then inserts it into light salt water. ② When you are away from home, take out the vase and put it in the fruit and vegetable box of the refrigerator, which can keep it from fading for a long time. When you come back, take it out and put it in a vase, which can be lifelike. ③ Dissolving aspirin in water can prolong the flowering time of bottled flowers. 8. Adjust the flowering time. Put the flower seeds, plant bulbs or cuttings into plastic bags, then put them in the refrigerator, and take them out for planting when appropriate. The flowering time can be adjusted at will. 9. Frozen potted flower recovery method In the cold spring season, potted flowers will be held outdoors.Frozen stiff. In this case, the potted flower can be wrapped in three layers with waste newspapers with strong water absorption. When wrapping, be careful not to damage the branches and leaves of the potted flower and avoid direct sunlight. Let it stand for a day so that the temperature of potted flowers will gradually rise. After this treatment, the frozen potted flowers can be revived. 10. Clivia summer method In the midsummer season, the temperature is often above 30 C, which is extremely unfavorable for Clivia&;s growth. To this end, scaffolding is commonly used to cool down. You can also bury Clivia in the sand together with the basin (bury the basin), and then sprinkle water on the sand once a day in the morning and evening. In this way, the basin soil can be kept moist, and more importantly, the purpose of cooling can be achieved by the endothermic effect of water evaporation in the sand. 11. Hydrangea turns blue. Nail a rusty nail into the root of hydrangea, and hydrangea will obviously turn blue. 12. Cleaning method of lime soil on plants When cleaning many families, whether in winter or in midsummer, potted flowers are generally washed under the tap, which often affects the growth of plants due to sudden temperature changes. If it is a foliage plant, you can dip it in water and clean it piece by piece along the branches and veins. Other plants can be washed with a watering can. 13. flower cultivation and deodorization method indoor flowers will emit an unpleasant smell if they use fermented solutions as fertilizers. If orange peel is put into fertilizer solution, the smell will be eliminated. At the same time, orange peel itself is also a good fertilizer. 14. Four methods of self-made pesticides ① Take 200 grams of green onions, chop them up, soak them in 10 liters of water for one day and night, filter them and spray them on the affected plants several times a day for five days. (2) 200-300 grams of garlic, mashed juice, diluted with 10 liters of water, immediately used to spray plants. (3) 400 grams of tobacco powder, soaked in 10 liters of water for two days and nights, filtered out the tobacco powder, added with 10 liters of water and 20-30 grams of soap powder when used, evenly mixed and sprayed on the damaged flowers and trees. (4) 10 liters of water and 3 kilograms of plant ash are soaked for 3 days and nights, and then the plants can be sprayed. 15. Weeds are very prolific. Weeds in the yard have just been pulled out and grow everywhere in a few days. In this case, don&;t pour out the salt water that is usually used to pickle duck eggs or pickles. In the season when weeds are flourishing, pour salt water on weeds for three or four times to stop the growth of weeds. In addition, the water for boiling potatoes can also remove weeds in the courtyard or aisle. It is also very effective to weed with bleaching powder water. The method is to sprinkle water on the ground to be weeded, so that the land is soaked. After 24 hours, it is watered with bleaching powder water, and the weeds will soon turn yellow and die. 16. How to plant Milan Milan has a strong aroma and is the most suitable flower for planting in the family. It likes temperature and sunshine, and the flowerpot should be placed in a sunny place. It loves fertilizer, and it is best to use fish pond mud to break it as culture soil, and dry pig and chicken manure and phosphorus-rich fertilizer as base fertilizer. It blooms many times and must be supplemented with nutrients in time. After each flowering, nitrogen, phosphorus and potassium fertilizer should be applied topdressing. When the temperature is high, the leaves should be sprayed with clear water before sunset to promote their vigorous growth. Common sense of plant cons: should distinguish the requirements for light :1.

Top dressing outside the roots; 2. Urea topdressing can also be used to spray urea water on the leaves; 3. Potassium dihydrogen phosphate is beneficial to flower bud differentiation, and can also make flowers large and colorful; 4. For yellow leaves with iron deficiency, spraying ferrous sulfate is the best. Such as camellia, gardenia, smiling, etc.; 5. Boron water can prevent falling flowers and buds, which is very beneficial to improve the number and quality of flowers; 6. Pay attention to the amount of topdressing: 0.2%-0.3% for urea and potassium dihydrogen phosphate, 0.3%-0.5% for ferrous sulfate and 0.05%-0.1% for boron; 7. Topdressing time is usually in the morning.8-10 o&;clock or in the evening, don&;t ignore the spraying on the back of th:, we should master the principle of &”;prevention first&”;, strengthen management, and pay attention to the maintenance of ventilation, light transmission, watering and fertilization. Make flowers and trees grow sturdily and enhance their ability to resist pests and diseases. Once pests and diseases are found, measures should be taken as soon as possible to achieve &”;early treatment, small treatment and treatment&”; to prevent their spread. The common diseases and insect pests of flowers are introduced as follows: 1. Insect pests (1) Aphids are small bluish-yellow insects that harm almost all flowers and trees. Between spring and summer, it is often concentrated on new shoots or flower buds such as Chinese rose, pomegranate, oleander and chrysanthemum. Sucking sap with mouthparts will cause the tender leaves to curl and shrink, which will not only affect the growth and flowering, but also make the plants wither. Aphids can produce 20-30 generations a year and can overwinter. Prevention and control m: is spray:. One is to soak the first 5 grams of cigarettes in 70-80 grams of water for 24 hours, rub them a little, filter the dregs with gauze, and then spray them. The second is to use 1: 200 washing powder water (soap solution water). In order to improve the effect, add a few drops of vegetable oil, fully stir it, and spray it with a sprayer when there is no oil flower on the surface. (2) Spiny moth, commonly known as stinging caterpillar and itchy chili pepper. This pest eats leaves of Chinese rose, Prynne, Peony, Pomegranate, Plum Blossom, Lotus and Rose. When the damage is serious, the leaves of the whole pot of flowers are eaten up in less than a few days. Spiny moths lurk on the back of leaves, which are often ignored if they are not careful. It occurs twice a year, once in early June, once in late June, and overwinters after mid-October. Control m:, the damaged leaves can be removed and burned. Spraying 90% crystal trichlorfon with 1000-1200 times solution (that is, adding 1 gram or more to 1 kilogram of water) or 500-800 times solution of 50% fenitrothion emulsion. (3) Tetranychus urticae, also known as red spider. Rhododendron, rose, bunch of red flowers, begonia, real cypress, kumquat, cactus and cypress are often harmed, among which Rhododendron and real cypress are the most seriously harmed. Tetranychus urticae is small and red, which is hard to see with naked eyes. I like to suck sap on the back of the leaves, and the injured leaves turn yellow, and many small white spots appear, and soon they turn yellow and fall off. Tetranychus urticae has a strong reproductive ability, which can produce more than 10 generations a year, and often breeds in high temperature and low humidity environment. Prevention and control methods: Weeds in pots and overwintering insects w:. At the time of damage, 40% dimethoate emulsion is 1000-1500 times (that is, 1 kg of water is added with 1-1.5g of dimethoate), or 40% dicofol emulsion is sprayed with 2000 times. (4) Long-horned beetles, also known as stem borers and heart borers. It often harms grapes, roses, azaleas, peaches, apricots and plums. Prevention and control m: cut off the damaged trunk and captured it. Or remove it with a knife.After insect dung and sawdust, inject 1: 50 times solution of omethoate from the wormhole, and then seal the hole with mud. (5) Scarab, also known as white silkworm and clay silkworm. Its larva is called grub, which has a variety of feeding habits and is the main underground pest of many flowers. Prevention and Cur: can promote the death of overwintering generation. During the activity period, 800-1000 times of 50% marathon emulsion is poured; Protect natural enemies. 2. Diseases (1) Powdery mildew, also known as powdery mildew, harms rose, rose, boxwood, kumquat, etc., and often harms leaves, stems and flower stalks of flowers and trees. A layer of white powder appeared on the surface of the affected area, and the leaves withered when the condition was serious. This disease is easy to occur in a hot, humid and unventilated environment. The control method can be sprayed with drugs such as Tobuzin and carbendazim. (2) White silk disease, which harms rose, jasmine, clivia, pomegranate, peach leaf coral, orchid, chrysanthemum and so on. At the onset, the stem base was brown and rotten, and the mycelium was spun silk-like, white at first, and then turned yellow to brown. This disease mostly occurs in the summer season when the soil is wet, rainy and hot. Prevention and control methods Pot soil should be disinfected, and at the same time, attention should be paid to environmental ventilation to avoid over-dense cultivation and pruning diseased branches. Spray 500 times of 50% carbendazim wettable powder regularly before onset. (3) Leaf spot disease, also known as black spot disease and brown spot disease. It is harmful to rose, camellia, azalea, rose and chrysanthemum. First, black spots appear in the middle of leaves, and then the leaves turn yellow and fall off. Most of the causes are sultry environment, lack of v: pays attention to improving environmental conditions, and can remove the damaged leaves and burn them at the initial onset. It can be controlled by spraying 1% Bordeaux mixture once every 7 days and 4-5 times in the whole growth period. Indoor foliage plant management cal:&;s calendar is based on Shanghai and Nanjing. How to control pests and diseases by raising flowers at home has been delayed for more than one month in the northern region. The temperature in January is cold and dry. During the day, plants that like semi-shade and light will be placed on the south window sill to receive sufficient light. At night, place it 1 meter away from the window sill, or cover it for insulation. Plants that like high temperature need to be covered with plastic film or placed in an incubator made of glass during the day. If possible, artificial light sources can be used to supplement the light to increase the amount of light. In rooms with low room temperature, heating measures should be taken to prevent freezing injury. Shade-tolerant plants are placed in the light, and dormant plants are placed in the dark. Water it onc: will not apply fertilizer or apply a small amount of potassium fertilizer. Wipe the leaves with a wet cloth to remove dust and moisturize. Cut off dead branches and yellow leaves in time. February is cold and dry, with occasional warm weather. Keep the light and temperature, as in January. Even if there is warm weather occasionally, you should not suddenly move outdoors to bask in the sun, or remove the heat preservation facilities, otherwise it will easily lead to freezing injury. Water control and fertilizer control are also the same as in January. Cold-tolerant plants began to put pots, pour pots and change pots. For example, some bamboos, nandina domestica, etc., should be carried out in warm weather in the later period. Cutting cold-resistant plants such as Nandina domestica and Illicium verum. Plastic trimming is the same as in January. In March, the temperature began to rise, and the light intensity gradually increased, but there was still a cold current. In addition to liking high temperature and some parts,Warm plants continue to take anti-freezing measures, and other plants can gradually remove the heat preservation facilities to adapt to the room temperature, and be properly ventilated, but the milk can not be moved outdoors immediately, and can take turns to bask in the sun. Maintain humidity, apply a small amount of fertilizer, and increase the number of watering appropriately to make strips for plant germination, but the soil should not be too wet and maintain a certain air humidity. Sprinkle water on the leaves at noon in a warm atmosphere. Apply a small amount of all-nutrient fertilizer or nitrogen-biased phosphate fertilizer. Continue to cut cold-resistant plants such as Illicium verum, Euonymus fortunei, Cinnamomum cassia, and Trachelospermum. Propagation of Cinnamomum cassia by ramets. Most pots can be changed, and combined with pot changing, root pruning, posture adjustment, base fertilizer application, ramet propagation, etc. In April, the temperature continued to rise, the sunshine was abundant, the rain began to increase, and most plants began to sprout. Some plants that like high temperature still need heat preservation management. Most plants can fully receive sunlight and be properly ventilated. Plants that like light, as well as those that are cold-resistant, can be exercised step by step and placed outdoors to see the light alternately, so as to maintain a good appearance. Except for those who have just put in pots, poured pots or changed pots, the rest can be topdressing. Seeding seedlings and cutting seedlings have started to grow normally, and thin fertilizer water can also be applied. The number of watering times increases, and it is wet when it is dry. It is often sprayed on the leaves to increase the humidity of the air. Continue to cut cold-resistant plants such as Cinnamomum cassia and Euonymus fortunei. Calla lily and star anise gold plates began to be sown in the second half of this month. Continue to pay close attention to the work of loading, pouring and changing pots. As the plants sprout and spread their leaves, they should be topped and topped in time. Rubber trees, purple-backed jazz beds, etc. Binding bracket for vine plants. In May, the temperature was getting higher, the sunshine was abundant, the rain increased, and the plant growth began to . First of all, do a good job of shade-avoiding and shading some shade-tolerant plants to prevent sunburn and scorching, and properly ventilate them. The rest of the plants can fully accept the sun and promote the flourishing of branches and leaves. Topdressing can be carried out before watering, and the frequency and dosage should be increased appropriately, but the stem and leaf should be prevented from being contaminated. After topdressing, water and spray water on the leaves in time. Watering is basically once a day, morning and evening, and the number of foliar sprays increases. Hard-branch cuttings such as Japanese coral, variable leaf wood, Liriodendron chinense, creeping green velvet and octagonal gold plate can start in the second half of this month. Mahonia, octagonal golden plate, calla lily, etc. continue to collect seeds and sow. Red mulberry, Liriodendron, etc. pour pots and change pots. In rainy days, the sowing seedlings are thinned and fixed. In June, the temperature rises, the humidity is high, the sun is strong, and plants grow rapidly. Cold-tolerant plants also enter the long period of life. Do a good job in shading and sun protection of shade-tolerant and semi-shade-tolerant plants, and pay attention to indoor ventilation. Provide sufficient moisture, and pay attention to maintaining air humidity in sunny and hot weather. The frequency and dosage of topdressing should be increased. Step up the hardwood cutting of variable leaf wood, rubber tree, octagonal gold plate, Liriodendron chinense and creeping green velvet. Do a good job of cutting the stem and dividing the plant for propagation. Pay close attention to changing pots of a few plants such as Liriodendron. Pay attention to prevent pests and diseases this month. Because of the hot and humid weather, it is particularly easy to induce fungal diseases. Spray Bordeaux once every 7-10 days. If pests and diseases are found, they should be isolated and treated in time. In July, the climate is hot, and high temperature weather often occurs. Although the precipitation is large, it is mostly runoff from the surface, and the air humidity is low, which has a negative impact on plant growth. Mainly pay close attention to measures such as shading, spraying water, ventilation and cooling, and humidification. Take no measures for shade-tolerant, semi-shade-tolerant and light-tolerant plantsWith the same degree of shading measures, some light-loving plants should also be shaded at noon in hot and dry weather. Special attention should be paid to cutting seedlings and sowing seedlings. Strengthen ventilation and ventilation measures. Watering must be sufficient and timely, and it can be done twice a day in the morning and evening on dry days. Avoid watering at noon, put a basin side by side and increase the number of water sprays on the leaves and the ground to cool down and moisturize. Topdressing should be thin, mainly nitrogen fertilizer, and applied before watering. Summer sleeping plants control water and fertilizer. Spores of Cuiyuncao and pteridophytes are mature, and they can be collected and spread at any time. Red mulberry and Liriodendron chinense can continue cutting propagation. Actively prevent and control pests and diseases. Same as in June. In August, the climate is hot and dry, and there is still extremely hot weather. In the latter part of the year, the temperature difference between day and night is large, which is conducive to the growth of plants. Lighting and temperature management are the same as in July. Water and topdressing management are the same as in July. In September, the temperature gradually dropped, the temperature difference between day and night was large, and it was cool in the morning and evening, and most plants appeared the second growth peak. Some semi-shade plants began to receive direct sunlight gradually. Light-loving plants can get enough light all day, but they still need ventilation. The amount of watering is still sufficient and the air humidity is maintained. The amount and frequency of topdressing are old, gradually increasing the proportion of potassium fertilizer and reducing nitrogen fertilizer. Reineckea carnea and calla lily are propagated by equal plants. Proper shaping and pruning. In October, the climate gradually cooled and the growth rate of plants began to slow down. Except for shade-tolerant plants, other plants gradually receive full light. Plants that are not hardy have moved indoors one after another. For plants whose growth is gradually weakened, after applying fertilizer once in the first half of the year, water and fertilizer control will be started. For plants that grow normally, the amount of water should not be too much, so as to prevent them from growing in vain, resulting in weakening cold tolerance, and potassium is the main fertilizer. Hosta is propagated by equal roots. Ophiopogon japonicus and other exploitable species are spread and propagated. The temperature dropped significantly in November, and the first cold wave began to appear. Most plants grow slowly, and a few plants gradually enter dormancy. Except for cold-tolerant plants, other plants should be kept in human rooms. Take measures to block the gaps between doors and windows to prevent the cold air from coming at any time. Except for shade-tolerant plants, the rest can fully receive sunlight. Plants that like high temperature should take appropriate heat preservation measures according to the situation, and take heating measures when necessary. Most plants need to control water and cut off fertilizer to keep the soil properly dry. Collection, sowing and propagation of palm seeds. Trim at any time and keep a good posture. If the pruned branches are properly stored, they can be used for cutting in the coming year. The climate in December is cold and dry. Check the cold protection m: plants with high temperature can be placed in an incubator made of plastic film or glass to improve the heat preservation effect. Most plants can fully receive sunlight, and when the sunlight is insufficient, artificial light sources are used to supplement the light. At night, the flowerpot should be placed 1 meter away from the doors and windows, or it can be covered to keep out the cold. In winter, dormant plants are placed in the dark. Continue to control water and cut off fertilizer. Water should be poured once every 3-4 days or longer, and the water temperature should be equal to or slightly higher than the air temperature, and water should be poured at noon. In winter, the dormant plant instrument can keep the soil in a certain humidity. Indoor heating often leads to low air humidity, so you can often wipe the leaves with a wet cloth to keep moisture and clean. Seeds of Nandina domestica and other plants are stored or sown as they are collected.
