The role of shading nets is to shave and cool down. In the absence of strong light and low temperature, shading nets cannot always [sleep" on sheds. Uncovering the shade nets requires a flexible grasp of the light intensity and temperature requirements according to the weather conditions, types of vegetables, and different growth periods of vegetables. Generally sunny cover, cloudy exposing; noon cover, sooner or later, exposing; pre-covered, late exposing. If there is more rainy weather and the temperature is not too high, after the vegetable is planted, the shade net can only be covered in the mild seedling period. If a black shading net is used, it will be covered only in the sunny midday. Sunshade net cover for a long time will affect the photosynthesis of vegetables and is not conducive to the normal results of vegetables. Therefore, shade nets should be covered only in the brightest part of the sunny day at noon. The specific time is from 10:30 am to 2:30 pm. If these measures are still difficult to reduce the temperature inside the shed, you can use spray or irrigation methods to cool down. In addition, spray 0.1% zinc sulfate or copper sulfate solution can enhance the plant's resistance to heat, anti-cracking, anti-sunburn ability.
