The hail net is a kind of agricultural protection facility, which is mainly used to prevent hail from damage to crops. As a weather phenomenon, hail often appears with strong convection weather. Its power is enough to destroy large farmland, orchards and vineyards. In recent years, with the frequency of extreme weather incidents, the use of hail nets has been widely used in agricultural production, and it has become an important means to ensure the stable output of crops.
1. The principle and function of the anti hail net
The hail net is usually made of high -intensity polyethylene (PE) or other durable plastic materials. It is woven into a mesh structure and has the characteristics of corrosion resistance, ultraviolet rays, and anti -aging. This mesh structure can effectively absorb and disperse the impact of hail, causing the hail to break or roll off the mesh, thereby avoiding directly cracking down on crops.
Main function:
Hailing: This is the core function of the hail net. By covering above the crop, the hail net can minimize the destructive power of the hail, and protect the crops from hail strikes.
Bird -proof harm: The fine structure of the hail network can also effectively prevent birds from entering farmland pecking crops, especially for fruits, vegetables and planting seeds.
Weaken sun radiation: The coverage of the hail net can also reduce a certain amount of sun radiation, and it plays a certain shading effect on crops in high temperature weather and reduce water evaporation.
Wind -proof sand: In multi -wind area, the hail net can also prevent the effect of preventing the wind and dust and damaging crops.
Second, the application scenario of the hail net
The hail net is widely used in many areas in agriculture, especially in the planting of fruit trees, grapes, vegetables and greenhouses.
Orchards: For fruit trees that are susceptible to hail, such as apple, pear, and peaches, etc., the orchard, especially apples, pears, peaches, etc., it provides solid protection. Large -area orchards are prone to suffering from a hail season in the hail season, and the application of hail network can effectively reduce losses.
Vineyard: Grape is a kind of economy, often used for winemaking and raw food. Once the hail falls in the vineyard, it will not only damage the fruit, but it may also destroy the entire vine in severe cases. Installing the net hail can significantly reduce the damage of hail to grapes and ensure the production and quality of grapes.
Vegetable Base: Vegetables grown in open -air, such as tomatoes and cucumbers, are often devastated when hail strikes. By using hail nets, vegetable farmers can protect vegetables from natural disasters and ensure the smooth growth of vegetables.
Greenhouse: Although the greenhouse itself provides a certain protective role, some greenhouse tops may still be damaged by hail impact. In order to ensure the safety of the greenhouse, some farms are equipped with hail nets on the top of the greenhouse to provide dual protection for crops.
Third, installation and maintenance
The installation of the hail network needs to be designed and planned according to the type of crops, the scale of farmland and the geographical environment. Generally speaking, the support structure of the hail network is made of steel pipes or stakes and other materials, laying the net above the bracket to cover the entire crop area.
Installation points:
Scholarly stable: Because the hail network needs to bear a certain weight of hail, the bracket must be firm and reliable and can carry the impact of hail.
Tight mesh: The hail net should be laid tightly to avoid loosening the net surface and affect the protection effect.
Regular maintenance: The long -term exposure of the hail net is exposed to the sun and rain for a long time, and it may be affected by aging. Therefore, it is necessary to check and replace the damaged part regularly to ensure its effectiveness.
4. Future development trend
With the frequent weather caused by climate change, the importance of the hail network will become more prominent. The advancement of science and technology has made the materials of the hail net more light and durable. In the future, intelligent technology may be combined with intelligent technology to achieve automated control protection systems. For example, through the analysis of the weather forecast data, the hail and anti -hail nets are developed in advance to reduce the burden on manual operation.
At the same time, with the development of agricultural scale and modernization, the scope of the promotion and application of hail nets will continue to expand to provide more reliable guarantees for global farmers. This is not only the protection of crops, but also an effective means to improve agricultural anti -risk capabilities in the context of global food security.
Conclusion
As an effective agricultural protection facility, hail network is providing solid protection for global agriculture. It builds a protective barrier for crops by physical methods, reducing the infringement of crops such as hail and bird damage, and improving yield and quality. In the future, with the advancement of technology and the widespread application of technology, the hail network will play a greater role in agricultural production and become an important tool for ensuring the safety of crops.
