There are many advantages to using agricultural shade nets to cover cultivation in summer. The following points should be paid attention to in order to produce good results.

　　1. Agricultural sunshade nets of different specifications and colors have different degrees of shading; different types of vegetables have different light intensity suitable for photosynthesis. Therefore, the appropriate agricultural sunshade net should be selected according to the type of vegetables and the light intensity during the covering period.

　　2. Choose the appropriate covering method according to local conditions Greenhouses, greenhouses, medium sheds, small sheds and other protected land facilities in many areas in the north are generally only used for thermal insulation and cold-proof cultivation in autumn, winter and spring, and are mostly idle in summer. Using the agricultural sunshade net to cover, one to two more crops of leafy vegetables with a short growth period can be produced a year, or seedlings can be raised to improve the utilization rate of the greenhouse frame and increase the yield and income.

　　3. Standardization of management work The main purpose of agricultural shade net covering cultivation in summer is shading and cooling, of which shading plays a leading role. The degree of shading is not only to choose a shading net with a suitable shading rate, but also to master the uncovering time. If the agricultural sunshade net is covered and then covered to the end, it will cause side effects such as leggy, chlorosis, disease, yield reduction and quality degradation caused by high temperature, high humidity and weak light.

　　The general principle of agricultural sunshade net management is: according to the weather conditions and the requirements for light intensity and temperature of different vegetables and different growth periods, flexibly grasp the time for uncovering the cover. The specific operating procedures are: before sowing, cover with floating surface, and open the net in the evening after emergence.
