Five Functions of Sunshade Net

200gsm shade net are mainly used in summer, especially in the south where the promotion area is large. Cultivating vegetables with sunshade nets in the south in summer has become a major popularized technical measure for disaster prevention and protection. The application in the north is also limited to the cultivation of vegetable seedlings in summer.

In summer (June-August), the main function of covering the sunshade net is to prevent the exposure of the scorching sun, the impact of heavy rain, the harm of high temperature, the spread of diseases and insect pests, especially to prevent the migration of insect pests.

1. Cool down in summer and autumn.

Cultivated vegetables in summer and autumn are covered with 12-mesh black or silver-gray nets. The shading rates are 65% and 45% respectively. The ground temperature of the layer drops by 3-6°C, so it can avoid the damage of strong light and high temperature, and is beneficial to the normal growth of crops.

2. Moisturizing and drought resistant.

After covering the sunshade net in the dry season, it can reduce the solar radiation heat, reduce the greenhouse temperature, and reduce the exchange speed between the air in the covered area and the outside world, thereby significantly increasing the relative humidity of the air, which is conducive to moisturizing and drought resistance.

3. Thunderstorm and hail protection.

After the sunshade net is covered, the direct impulse of the rainstorm can be reduced by more than 90%, which can reduce the mechanical damage of vegetables caused by heavy rain and hail, and reduce the loss of soil and fertilizer.

4. Prevent diseases and insects.

After being covered with silver and black sunshade nets, aphids were significantly reduced, viral diseases were significantly reduced, and the disease prevention rate was about 90%.

5. Increase production and income.

After vegetable cultivation is covered with 70% shade net, it is generally listed 10 to 20 days earlier than open-air cultivation, and the yield is increased by 20% to 80%.

The use of sunshade nets can save 25% to 50% of labor input, and can save 50% to 70% of costs compared with traditional reed curtains covering sunshades.
