It is suggested to remove the dragon spit beads, smooth sailing, discolored leaves, grape lotus, green snail and cymbidium uniflora indoors at night and put them on the balcony. If you don&;t want to separate the house, leave Clivia and orchids.
Orchids are good for purifying the air. Some plants photosynthesize, absorb carbon dioxide and release oxygen during the day, and breathe, absorb oxygen and release carbon dioxide at night, which is suspected of competing with people for oxygen.
Special reminder: Don&;t treat the living room as a &”;flower house&”;. If there are too many flowers and trees, and the indoor ventilation is limited, the air will be as thin as in the plateau. Especially at night, most flowers will release carbon dioxide and absorb oxygen to compete with people. Moreover, most of the living rooms are closed at night, and the carbon dioxide breathed by the soil, human body and pets in the flowerpot will increase the concentration of carbon dioxide, causing human hypoxia and affecting health, but it will have the opposite result.
Growing too many flowers indoors is harmful.

After the improvement of housing, people always hope to plant some flowers and plants in the room to improve the indoor ecological environment. But experts pointed out that the more indoor flowers in winter, the better. Only two pots of medium-sized and large plants should be put in an HOS house of about 15 square meters, while three or four pots of small plants can be put. Too many pots are harmful.
It is popular in society that it is not advisable to raise more flowers and plants indoors on the grounds that plants have to compete with people for oxygen. Wu Zhixing, a senior engineer of Shanghai Botanical Garden, told reporters that this statement is one-sided. Scientific indoor flower cultivation should make correct selection of plants. Flowers and plants can carry out photosynthesis and release oxygen under the irradiation of sunlight during the day, which is beneficial to people; But some plants will spit out carbon dioxide at night, which is harmful to human body and health.
Wu Zhixing said that the stomatal structure of cactus and succulent plants is specific, and the oxygen formed in photosynthesis will not be released until night, so it can be viewed indoors. For plants that release carbon dioxide at night, they should be moved outdoors at night.
Keep flowers indoors to avoid poisonous plants. For example, Rhododendron, Mimosa, Evergreen, Tripterygium hypoglaucum, Calla lily, Varicosa angustifolia and oleander, etc. If these plants are planted outdoors, they are generally untouched or eaten, and can be used for viewing; However, the leaf juice of Christmas flowers often planted in winter is poisonous, so we should be careful.
