Shading net is a kind of protective covering material for agriculture, fishery, animal husbandry, wind-proofing and soil cover, etc. After covering in summer, it plays the role of sunlight blocking, rain blocking, moisturizing, and cooling. After covering in winter and spring, there is also a specific role of heat preservation and humidification.
Covering the shading net directly on the surface of leafy vegetables, which planted in winter and spring, could prevent low-temperature harm. Because sunshade net is lightweight, there will not make the high leafy vegetables fall, bend, or reduce their commodity nature.
Shade netting has a certain degree of air permeability, so the surface of the leaves is still dry after covering, which reduces the occurrence of diseases. Shading net also has a certain degree of light permeability; after covering, the vegetables will not become yellow or rotten.
Shading net is mainly used in summer. Using shade nets to cultivate vegetables has become a primary agricultural measure. The main function of covering shade netting in summer is to prevent the irradiation of the hot sun, the impact of heavy rain, the harm of high temperatures, and the spread of pests and diseases.
After covering the cooling and windproof shade net, the exchange speed of air decreases between the greenhouse and the outside; thus, it is an apparent increase in the air humidity of the greenhouse. At noon, the humidity increase value is the largest, generally reaching 13-17%. Because the air humidity is high, the soil evaporation decreases, and the soil humidity increases.
Shading net is made of polyethylene (HDPE) (high-density polyethylene, PE) with UV stabilizer and anti-oxidation treatment, which has strong tensile strength, aging resistance, corrosion resistance, radiation resistance, lightweight, etc.
Sun shade net is mainly used for the protective cultivation of vegetables, mushrooms, flowers, edible fungi, seedlings, medicinal herbs, ginseng, lucid Ganoderma, and other crops. It is also widely used in aquatic poultry farming. Shade netting has effectively increased the production of different industries.
Shade nets are knitted with crossed warp and weft wires by a warp knitting machine. If both warp and weft wires are interwoven by round wire, it is monofilament shade nets.
The net, which is knitted with flat wire in both warp and weft, is tape shade net. This kind of shade netting has a low weight and high shading rate, mainly used for shading and sun protection in agriculture and garden.
When warp wire is flat wire with round weft wire, or warp wire is round wire and flat weft wire, the net is mono+tape type shade net.
The method of identifying high-quality shade netting is as below:
1. The net surface is flat and smooth; The weaving is neat and even; The warp and weft wire is clear and bright.
2. The surface finish of the net is excellent. The color is very bright and clean.
3. The net has moderate flexibility and elasticity without hardness and roughness.
4. The net is packaged formally and marked clearly with shading rate, specifications, size, etc.
5. The net has no strange odor and only a slight plastic smell.
The above is the general introduction of shading net. If you want to know more about sun shading net, please contact with Shijiazhuang Qibang Imp&Exp Co.,Ltd.
