Spend into the bedroom efficacy of multi-efficacy one: filter air in the summer room air conditioning utilization rate is very high, doors and windows are closed, air circulation will be bad. Therefore, it is appropriate to raise some flowers that can filter the air in the bedroom. Most flowers carry out photosynthesis during the day, absorb carbon dioxide, release oxygen, breathe at night, absorb oxygen and release carbon dioxide, while cactus, tile pine and other types are just the opposite. Keeping these air-filtering flowers in the same room with other flowers can effectively balance the content of indoor oxygen and carbon dioxide and keep the indoor air fresh. Efficacy 2: detoxification orchid, aloe, tiger tail orchid can absorb a large number of indoor formaldehyde and other pollutants, eliminate and prevent indoor air pollution.

Milan, orchids, cloves, cactus, Tianzhu and so on can effectively purify the air. Camellia can resist the damage of harmful substances such as sulfur dioxide, and crape myrtle has strong resistance to indoor sulfur dioxide, hydrogen chloride, chlorine, hydrogen fluoride and other toxic gases. Plum has the ability to monitor the pollution of sulfur dioxide, hydrogen fluoride, hydrogen sulfide, ethylene, benzene and aldehydes in the environment. Once sulfide appears in the environment, markings will appear on its leaves, or even withered and yellow. Because flowers have these functions, the room that has just been decorated is more suitable for raising these flowers. It should be pointed out that there is a limit to these functions of plants, so it is necessary to open windows frequently to make air convection.

It should be noted that although flowers have a lot of benefits, do not treat the bedroom as a "greenhouse". Most flowers release carbon dioxide and absorb oxygen at night, and most of the rooms are closed at night. coupled with the carbon dioxide exhaled by the soil, the human body and pets in the flowerpot, it will increase the concentration of carbon dioxide, cause hypoxia and affect health.

The leaf surface can also be sprayed with water properly. For acid-loving flowers, it is best to pour 0.2% to 0.3% of black alum to prevent chlorosis caused by iron deficiency. Some fleshy root flowers, such as orchids, can not stand the sun exposure, can be relatively dry at noon when spraying some water on the leaves moderately.

If the concentration is too high, it is easy to cause fat injury. Experts advise flowers how to control diseases and insect pests, which is an important link in the process of flower cultivation. The solution given by experts to this problem is: 1. Detergent kills white flies. White flies not only suck the leaf juice, but also secrete mucus to wither the leaves. You can mix a spoonful of detergent with 4 liters of water, spray on the leaves and spray once every 5 minutes and 7 days until the white flies are eliminated. two。 Milk kills ticks.
