Disaster prevention and mitigation: Hail nets are mainly used to prevent hail, storms and other severe weather from directly impacting apple trees, reducing damage to fruits and branches and leaves, thereby ensuring the yield and quality of orchards. According to research, the use of hail nets can effectively avoid or reduce economic losses caused by hail disasters.

Regulating microclimate: Hail nets can slow down changes in air humidity and reduce orchard temperature. Within a height range of 1.5 meters, the atmospheric temperature can be reduced by 3 to 8°C, which helps to reduce the damage of sunshine to apples. At the same time, hail nets can also make the temperature rise in the morning and cool down at night in the orchard relatively slow, which is conducive to the movement of water vapor in the soil and the decomposition of organic matter, and improve soil nutrients.

Enhance soil water holding capacity: Hail nets can reduce the exchange between soil moisture and the atmosphere, reduce ground evaporation, thereby enhancing the water holding capacity of the soil, and help the growth and development of fruit tree roots.

Improve the physiological condition of fruit trees: In apple orchards with hail nets, leaf temperature is reduced, leaf water potential value is increased, and canopy chlorophyll and carotenoid concentrations are increased. These changes are conducive to photosynthesis and growth and development of fruit trees. However, it should also be noted that the leaves under the hail net may remain wet for a longer time, increasing the risk of disease.

Significant economic benefits: Although the initial investment cost of the hail net is high, its service life is long (generally up to 5 years) and can significantly reduce the economic losses caused by natural disasters. In the long run, the use of hail nets can significantly increase the income level of fruit farmers.
