Shade net small encyclopedia

Oct. 14, 2022

Shading nets (covering nets, planting nets, breeding nets) are special protective covering materials for agriculture, fishing, animal husbandry, windbreak, and soil covering. After covering in summer, it plays a role in blocking light, rain, moisturizing and cooling. After covering in winter and spring, there is a certain heat preservation and humidification effect. Generally, the leafy vegetables planted in winter and spring are covered with the sunshade net directly on the surface of the leafy vegetables (covered by floating surface) to prevent low temperature damage. Because of its light weight, it is only about tens of grams per square meter, which is not suitable for tall leaves that have grown. The dishes will not overwhelm, bend, and reduce the commerciality. And because it has a certain air permeability, the surface of the leaves is still dry after covering, which reduces the occurrence of diseases. It also has a certain degree of light transmittance, and it will not "cover yellow and rot" after covering.

Moisturizing principle: [1] After covering the sunshade net, due to the cooling and windproof effect, the communication speed between the air in the covered area and the outside world is reduced, and the relative humidity of the air is significantly improved. High humidity reduces soil evaporation and increases soil moisture.

The sunshade net is made of polyethylene (HDPE), high-density polyethylene, PE, PB, PVC, recycled materials, new materials, polyethylene propylene, etc. Aging resistance, corrosion resistance, radiation resistance, lightweight and other characteristics. It is mainly used in the protective cultivation of vegetables, fragrant buds, flowers, edible fungi, seedlings, medicinal materials, ginseng, Ganoderma lucidum, Panax notoginseng, blueberries and other crops, as well as in aquatic and poultry breeding industries, and has obvious effects on increasing production.

Shade net classification

Round wire sunshade net: Since the sunshade net is woven by warp and weft, mainly by warp knitting machine, if both warp and weft are woven by round wire, it is round wire sunshade net.

Flat wire sunshade net: the warp and weft are both flat wire woven sunshade net is flat wire sunshade net, this kind of net is generally low in gram weight and high in shading rate, mainly used for agriculture and garden sunshade. This type is the most widely used, and our factory produces a large number of flat wire sunshade nets all year round.

Round flat wire sunshade net: the warp is flat wire, the weft wire is round wire, or the warp wire is round wire and the weft wire is flat wire, the shading net is round flat wire sunshade net. This type of sunshade net is generally used for Panax notoginseng planting, and various specifications can be customized according to contract orders.

References on how to identify high-quality shading nets:

1. The wire is flat and smooth, the flat wire and the gap are neat and even, and the warp and weft are clear and crisp.

2. The finish is good, with a sense of texture, deep black and bright, rather than the feeling of floating and bright.

3. Moderate flexibility, elasticity, no rigidity, no roughness, and a flat space texture.

4. There is no peculiar smell or odor, and some are just a faint burnt smell of plastic.
