1.The sunshade net has the function of weakening the strong light and reducing the temperature and soil temperature. After the sunshade net is covered, because the light intensity is reduced, the light radiation absorbed by the ground and plants under the net is reduced, and the temperature can be lowered from the surface.
The strong sunlight in summer can cause burns to the young and tender tissues of crops. The sunshade net can effectively avoid the strong sunlight around noon, relieve the suppression of the growth of crops by the strong light, and create a suitable photosynthesis environment.
2. Moisturizing.The shade cloth also has the effect of improving the air humidity and soil moisture content of the covering environment while shading and cooling, generally increasing the humidity by 5-10%.
At the same time, the wind is weakened, which reduces the evaporation of soil moisture and the transpiration of human moisture, which is conducive to maintaining the balance of soil moisture and human moisture.
3. Prevent rainstorm and hail. Because the sunshade net has a certain mechanical strength and is relatively dense, it can decompose the rainstorm into drizzle, avoid being damaged by the rainstorm, and the soil is not easy to harden, the open space is large, and the air permeability is good. Therefore, it is beneficial to improve the yield of crops and prevent the death of crop seedlings, so that the plants grow well.
If you first lay a layer of plastic film on the scaffold, and then cover the film with a layer of shading net, the effect of shading, cooling and rain protection will be more obvious.
4. Heat preservation. After the shading mesh is covered, it can prevent the thermal radiation (infrared radiation) of the ground at night, thereby slowing down the heat dissipation process and producing a certain thermal insulation effect. Therefore, in winter, the use of idle sunshade nets to replace traditional thermal insulation and antifreeze materials such as straw has good results.
5. Extend the growth period, crops will not grow when the temperature exceeds 25°C, and the shading net can reduce the temperature and maintain the air humidity and soil moisture content of the environment. It grows for more than one month in a year, and four years is five years of production, which can increase the yield.
