Attention should be paid to raising orchids on enclosed balconies in high temperature season.

Closed balcony compared with open balcony orchid, its air fluidity is poor, moisture retention is stronger, heating up faster, cooling slower, lighting conditions are slightly worse. Therefore, when you encounter a high-temperature season and raise orchids, you should pay special attention to it.

Raising orchids on a closed balcony in spring, autumn and winter is more suitable for orchid growth than an open balcony, but in summer, you should pay special attention to some of the following problems.

The main results are as follows: 1. The air fluidity of orchid cultivation on closed balcony is poor, and it is easy to breed harmful bacteria and cause soft rot and root rot due to rapid heating up and high humidity in summer. Therefore, in order to strengthen ventilation, you can open the window at night and replace it with outdoor air. This kind of natural ventilation is the best. During the day, electric fans are used to strengthen ventilation to prevent the growth of harmful bacteria. Air conditioners can be used to cool down if possible.

In addition, whether it is closed or open balcony, should pay attention to orchid timely replenishment of nutrients, summer can be targeted fertilization. It is recommended to use an organic nutrient solution for orchids and water 500 times to irrigate the roots.

2, closed balcony orchid cultivation, watering should be determined according to the dry and wet condition of the plant material in the orchid basin, not too wet, and the amount of water can be moistened by the plant material without stains. Proper control of water to dry the plant material for a day and then watering can prevent the plant material from multiplying harmful bacteria under high temperature and high humidity.

3, because the enclosed balcony heats up quickly, it is usually necessary to draw a curtain with better shade in the window to resist the strong sunlight and prevent the heating up too fast. However, we should also pay attention to the decrease of illuminance, which will affect the photosynthesis of orchids, so we can supplement light to maintain the normal photosynthesis of orchids.

Finally, we should do a good job in the prevention and control of diseases and insect pests. Adhere to the principle of "giving priority to prevention and combining prevention with prevention". High temperature season is the frequent season of orchid diseases and insect pests, first of all, we must do a good job in the cleanliness of the balcony, you can use disinfectant once a month to sterilize.

Orchids in high temperature and humidity environment are also easy to breed scale insects and thrips. Once found, they should be killed with drugs in time. Soft rot is the enemy of orchids in summer, resulting in serious losses if it is not handled properly. If it is found that soft rot occurs, the basin should be turned immediately, the diseased seedlings infected with bacteria should be cut off, the good seedlings without disease should be disinfected and replanted, and the isolation and maintenance should be done to prevent the spread of the disease.
