Hail net is a kind of protective net used to resist hail disaster in agricultural production. It is usually made of high-strength polyethylene (PE), polypropylene (PP), nylon and other materials. These materials not only have good weather resistance, but also can effectively disperse the impact of hail and protect crops from direct damage from hail. The structure of hola neta is usually grid-shaped, which can provide a kind of "barrier" protection for farmland under extreme weather conditions such as strong wind, heavy rain and hail.
The design concept of hola neta is based on the principle of physical protection, that is, through physical isolation or dispersion, the energy of hail can be effectively slowed down or transferred, thus reducing its damage to crops. At the same time, the hola neta has light and air permeability, and will not have adverse effects on the normal growth of crops.
According to different agricultural production needs and use scenarios, there are many types of red anti granizos, which can usually be classified according to the following standards:
According to the material classification
Polyethylene (PE) hola neta: PE is a common material for hail protection net, which has excellent tensile strength and weather resistance. Polyethylene red anti granizo is economical and widely used, which is suitable for the protection of most crops.
Polypropylene (PP) hola neta: Polypropylene hail protection net has high anti-aging performance and ultraviolet resistance, and is suitable for areas with high temperature and strong light. In addition, the polypropylene red anti granizo is light in weight and easy to install and maintain.
Nylon hola neta: Nylon hola neta has very good tensile strength and elasticity, and is suitable for extreme weather conditions such as strong wind and heavy rain. Nylon hail screen has good flexibility and can withstand strong impact, but its price is relatively high.
Classification by mesh size
Large-hole red anti granizo: this net has a large aperture and is suitable for the protection of crops with high light demand such as greenhouse planting and orchard. Large-hole red anti granizo can effectively prevent hail from entering, and at the same time ensure that crops can get sufficient sunlight.
Small-hole red anti granizo: The mesh structure of small-hole red anti granizo is dense, which is suitable for preventing the influence of small hail or sandstorm and other environmental factors. This kind of net is mainly used in areas with large sandstorm and small hail, and is also suitable for protecting some fragile crops.
According to the protection intensity classification
Light hola neta: It is suitable for mild climatic conditions and can effectively block the impact of small and medium-sized hail. Light red anti granizo is usually low in price and suitable for large-scale planting.
Heavy-duty hola neta: This net is thicker and stronger, which is suitable for hail and windy weather. Heavy-duty hail screen is usually used in high-risk areas and can withstand strong impact.
