Nowadays, the climate is changing rapidly, and agricultural production relies heavily on natural disasters, which is extremely unstable. Especially in recent years, natural disasters have occurred frequently. Facility cultivation can reduce the losses caused by natural disasters and play a role in disaster prevention and mitigation. The standardized orchard protection system is built on the basis of the orchard support system, which includes multifunctional anti hail nets, rain cloths, bird nets, etc.

Orchard hail prevention facilities are specially built for hail disasters, mainly including high-strength cement column support systems, multifunctional hail prevention nets, etc. The anti hail net is made of high-density polyethylene material, with a lifespan of over 5 years and a mesh aperture of 3 * 7mm, which can block small hail particles; The anti hail net is installed in an inverted ridge type, with a width requirement greater than the row spacing of 30 centimeters. The north and south ends are suspended to the ground, and the entire park is fully enclosed; The spacing between the mesh buckles between rows is 1.2-1.5 meters, and hail will roll down the inverted ridge shaped slope from the mesh buckle spacing to the rows without damaging the vegetation; The anti hail net should be closed before hanging fruits in spring and tied up at the top of the steel wire before snowfall in winter. It is recommended to use sunshade cloth for protection to extend the service life of the net.

The shading rate of hail prevention nets is around 10-20%, which can not only prevent hail disasters, but also have functions such as bird prevention, pest control, and sun burn prevention; At the same time, fully enclosed net rooms can also improve the microenvironment of orchards and prolong plant photosynthesis, especially in high-altitude areas where their effects are very significant.
