Changzhou Chenye Warp Knitting machinery Co., Ltd anti hail net has the following functions:
1. Prevent hail damage.
2, reduce the wind speed. It reduces wind speed by about 40-50%, with the greater the wind speed, the greater the effect.
3. Prevent sunburn. From 25% to 5-10%, the effect is very significant. In sunny summer, the temperature of fruits was about 7℃ higher than the air temperature, while the plots with hailstones only increased by 2-2.5℃. The effect on temperature is not significant (1-3℃).
4. Prevent bird damage. A completely closed hailstone net would have this effect.
5. Reduce transpiration. White webs generally have the smallest effect on light intensity (PAR8-12% reduction), black the largest (PAR18-25 reduction), and gray the moderate effect (15-17%). Hailstone nets of different specifications (shade rate 10%-25%), color and type can reduce optical radiation (PAR) by 12-27%. It can save 15-40% irrigation water. Increase the humidity by 2-6%RH.
6. It has an impact on tree potential and fruit yield and quality. Hailstone nets are white (transparent), gray, black, blue and red. Blue net is beneficial to vegetative growth, crown width can increase by 15%. The red net helps the red apple color. Fruit diameter remains the same or increases (but becomes smaller when the tree is overgrown). Color usually has no effect (but black mesh can affect the coloring of red apples). Soluble solids decreased. Delay ripening for 8-10 days. Fruit rust decreased. Lower fruit setting rate. Yield has no effect.
