And has a light, moderate hail net shading and other effects, and create favorable conditions for optimum crop growth, to ensure substantial reduction in vegetable chemistry of pesticides, so that crop output quality, hygiene, for the development of pollution-free green agricultural production provided strong technical assurance. Network also has to withstand hail storms and hail invasion erosion and other natural disasters. Hail net is widely used in vegetables, rapeseed and other system fan when the original species used for isolation incoming pollen, potatoes, flowers and other tissue culture hood compartment after detoxification and pollution-free vegetables, etc., can also be used in tobacco nursery for pest control, anti- diseases such use is currently the physical control of various crops, vegetable pests product of choice. Really let consumers eat "Fang Xincai" vegetable basket project for our country to contribute. Installation method hail nets, preferably in March, before the rainy season in northern, early is not necessary, you never know when late to hail, regret too late. It is very simple to install, as long as the ground floor flat hail nets pull up the top of the vine, grape plants from the top 5 to 10 cm, two network connection partly or nylon rope tied or joints, corners, too, in short firm can, and special attention is sure to pull the net to cut back so that it can be most effective against hail. Set an example to the vineyards: Vineyards erection hail net, there are three main materials, namely column, rack, hail nets, auxiliary materials rack pads, wire, pressure lines and so on. Select the column is a column supporting grid and the hail nets skeleton, play a supportive role, it must have a strong, durable characteristics, can be used more than 15 years. Choice of wood, cement columns and pillars three materials. Column two, one is the old park, through the uprights in the old park on the basis of binding a transformation from wood. To do with a hard wood miscellaneous wood, can afford grid, and hail hail net weight. Second, the new park, creating a new garden column, it will be the length of the cement column or columns to increase compared with the original vintage 60cm column formed directly hail net post. 2 Select the grid and grid requirements rack pads and durable materials with good ductility erection, used in the production Ф12 wire or Ф8-10 wire erected. Frame pad requirements of wear resistance, aging resistance, can produce tires, size 15 cm × 10cm 3 hail hail mesh material of choice for web material requirements: ① lighter weight, easy to set up; ② durable; ③ cheap; ④ to light little effect. After years of screening, nylon nets were eliminated due to the high price; barbed wire as the steel price increases year after year, large input costs, has been rarely used; production applications now hail net to polyethylene mesh-based. 3 Erection of grapes hail hail nets with mesh vine surface (scaffolding) or top (trellis) spacing of 50cm, hail mesh material color white is appropriate, based on years of experience, in order to prevent weathering and aging, to extend the useful life of the shelf in the grape buried after going to the net, tied one end of the net to recover or remove network storage.
