In particular, indoor winter plants should be strictly controlled watering, it is better to dry, otherwise it is easy to freeze. Open field cultivation, midsummer showers, pay attention to timely drainage, so as not to cause the whole area to die by waterlogging.

② Water plug Propagation: pay attention to changing water in summer.

The selection of water cuttings of Catharanthus roseus is similar to that of ordinary cuttings, and the truncated branches can be inserted directly into clear water, but always change water for cuttings, preferably every two days, to ensure the content and cleanliness of nutrients in clear water. When necessary, you can also add a few drops of nutrient solution to promote the rooting of water cuttings. Generally speaking, it takes about 20 days to take root.

Aloe vera has the ability to monitor air pollution, just like an air pollution monitor. Aloe is very sensitive to carbon dioxide in the air. In the sun, aloe uses carbon dioxide to produce organic substances conducive to growth, but the maximum concentration is 0.4%. If the concentration of carbon dioxide in the air exceeds 0.4%, the growth of aloe will be inhibited. As long as more than 10 micrograms of carbon dioxide per gram of air, it will damage chlorophyll, making aloe leaves brown or black spots, as a warning to remind people that it is time to open the window for air. What is more rare is that most plants carry out photosynthesis during the day, absorbing carbon dioxide, and at night, they need to release carbon dioxide through respiration. But succulent plants such as cactus and aloe usually carry out a kind of sedum acid metabolism, which can continue to absorb carbon dioxide at night and help purify the indoor air, especially in the bedroom.

In addition, when there are too many contents of hydrogen fluoride, hydrogen chloride, sulfur dioxide, carbon monoxide and ammonia in the air, the growth of aloe will also vary. Aloe is also good at absorbing formaldehyde and can absorb 90% of formaldehyde in 1 cubic meter of air under 24-hour lighting.

It is recommended to put a pot of aloe vera at the desk and bedside, especially in the winter when windows are not often opened, which can help you monitor air quality all the time. Aloe is resistant to drought and afraid of waterlogging. When watering, it should be watered gently along the edge of the basin, and do not rush hard.

Attention should be paid to the health and safety of purifying indoor environment by using flowers and plants:

We already know which plants can be used to purify and which plants have better purification effect, so how to calculate the number of plants in the room? Many friends do not know very well.

The director of the China Indoor Environmental Monitoring Committee mentioned that when using plants to purify formaldehyde pollution in the indoor environment, we should pay attention to three points:

1. Plant decontamination can be selected for medium and low pollution.

Generally, in the environment where the indoor environmental pollution is mild or moderate pollution and the pollution value is less than 3 times of the national standard, plant purification can achieve better results.

two。 Select and place plants according to different functions and areas of the room.

Under normal circumstances, about 10 square meters of the room, 1.5 meters high plants put two pots is more appropriate. Among them, the bedroom: should not put too many plants, is not conducive to sleep at night; toilet: can put green pineapple, rich bamboo and other shade and moisture-resistant plants; study: suitable for anthurium, orchids and other elegant plants; living room: loose-tailed sunflower, wealth trees and other tall plants; kitchen: cactus and other small plants resistant to oil smoke.

3. Four taboos of purifying indoor environment by using flowers and plants

Bogey incense: the fragrance of some flowers and plants is too strong, which will make people uncomfortable and even have adverse reactions. Such as night flowers, tulips, five-colored plum and other flowers.

Taboo Min: some flowers can cause allergic reactions. Such as rose, jade cloves, five-colored plum, hydrangea, geranium, bauhinia and so on, people touch them, often cause skin allergies, or even rash, strange itching unbearable.

Avoid poison: some ornamental flowers and plants are toxic, and attention should be paid to mimosa, poinsettia, oleander, yellow rhododendron and champion red, etc.

Avoid harm: for example, cactus plants have spikes, families with children or children's rooms should not be placed as far as possible. In addition, for the sake of safety, the plants in the children's room should not be too tall, and do not choose flowerpot racks with poor stability to avoid harm to children.
