Anti Hail net is a kind of non knot mesh fabric made of high density polyethylene (HDPE) with anti-aging, anti ultraviolet and other chemical additives. It has the advantages of high tensile strength, heat resistance, water resistance, corrosion resistance, aging resistance, non-toxic and tasteless, and easy disposal of waste. It can prevent natural disasters such as hail. It is easy to collect in normal use, and the service life can reach about 3-5 years.
Hail net covering cultivation is a new and practical technology for increasing production and environmental protection of agriculture. By covering the trellis and building artificial isolation barriers, the hail can be excluded from the net, effectively control all kinds of hail, frost, rain and snow, and prevent the damage caused by weather. It also has the functions of light transmission, hail prevention net and appropriate shading, creating favorable conditions suitable for crop growth, ensuring that the application of chemical pesticides in vegetable fields is greatly reduced, so as to produce high-quality and sanitary crops, which provides a strong technical guarantee for the development and production of pollution-free green agricultural products. The hail prevention net can also resist natural disasters such as storm scouring and hail attack.
Hail nets are widely used for isolating pollen in the production of vegetables, rapeseed, etc., and potato, flower and other tissue culture after detoxification and pollution-free vegetables, etc., and can also be used for insect prevention and prevention in tobacco seedlings. It is currently the first choice for physical control of various crops and vegetable pests.
The installation of the hail net is very simple. As long as the hail net is pulled up and laid flat on the top of the grape trellis, 5-10 cm away from the top of the grape plant, the connecting parts of the two nets are tied or sewn with nylon ropes, and the edges and corners are also the same. In short, it is enough to be firm. In particular, it is necessary to tighten the net so that it can most effectively resist the attack of hail.
