What is the function of plant sunshade net?

The function of plant shading net is shading, cooling and moisturizing; Prevent rainstorm and improve seedling rate; Prevention of diseases, birds and insects; Keep warm, cold and antifreeze.

1, shading, cooling and moisturizing. Covering the sun screen can reduce the light by 35% to 65%. When the surface temperature decreases by 9℃ to 12℃, and the soil temperature decreases by 5℃ to 8℃ from 5 cm underground to 10 cm, the surface water evaporation decreases and the relative humidity increases by 15% to 20%. ?

2. Prevent the rainstorm and improve the seedling rate. According to the test, covering the sunshade net can reduce the impact of rainstorm on the ground to 1/45. Because the microclimate in the net was adjusted, the seedlings grew normally and the survival rate was improved. Generally, the emergence rate can be increased by 10% to 15%, and the seedling rate can be increased by about 20%. ?

3. Prevention of diseases, birds and insects. The microclimate such as temperature, light, water and gas under its cover has changed, disrupting the law of insect reproduction and inhibiting the occurrence of some diseases. It can effectively prevent birds and rats from eating seeds and improve the emergence rate. ?

4, temperature, cold, frost. In early spring and late autumn, flowers and trees are covered with sunshade nets, which can prevent frost from directly hurting flowers and trees.

Benefits of using plant sunshade net

High temperature, scorching sun and showers in summer are easy to make flowers sick, burned and die. On a sunny day in summer, the light intensity at noon will be 1-2 times higher than that of ordinary flowers. If certain measures are not taken, most flowers will die of dehydration. Therefore, in summer flower production, shading is generally appropriate.

Shading can not only weaken the influence of direct light, but also significantly reduce the temperature. According to the test, shading can generally reduce the temperature in the greenhouse by 4-5℃. Generally, plastic shading net can be used for shading, the external shading effect is better than the internal shading, and the silver shading net is better than the black shading net.
