1.shading, cooling, moisturizing. Shading can reduce light exposure by 35 to 65 percent. Reduce the surface temperature by 9℃ to 12℃, reduce the underground soil temperature by 5℃ to 8℃ 5 cm to 10 cm deep, reduce the surface water evaporation, and increase the relative humidity by 15% to 20%.
2.rain prevention, improve seedling rate. According to tests, covering the sunshade can reduce the impact of a rainstorm on the ground by one in 45. By adjusting the microclimate in the net, the seedlings grow normally and the survival rate is improved. Generally, it can increase the emergence rate by 10% to 15%, and increase the seedling rate by about 20%.
3. Prevent disease, bird damage and insect damage. The microclimate of temperature, light, water and air under its cover changed, which disrupted the breeding rules of insects and inhibited the occurrence of some diseases. It can effectively prevent birds and mice from eating seeds and improve the emergence rate.
4. Keep warm, cold and frost proof. Early spring and late autumn flowers and trees covered with sunshade nets, can avoid frost damage to flowers and trees directly.
The benefits of using a plant sun shade net
High temperature, scorching sun and showers in summer are easy to cause flower disease, burn and death. In sunny summer weather, the light intensity at noon will exceed 1-2 times of the appropriate light intensity of general flowers. If certain measures are not taken, most flowers will lose water and burn.
In addition to weakening the influence of direct sunlight, shading also has the effect of significantly cooling. According to tests, shading can generally reduce the temperature in the greenhouse by 4-5℃. Sunshade generally available plastic sunshade net, outer sunshade effect is better than inner sunshade, silver sunshade net effect is better than black sunshade net.
