Application Of Non-woven Fabric In Vegetable Production
May 07, 2018

With polyester or polypropylene as raw material, the slice is made by extruding the filament through a screw and directly into a mesh. It is a cloth covering with good air permeability, moisture absorption and light transmittance. It has the effects of cold proof, moisture retention, frost prevention, anti freezing, light transmission, and air conditioning. It has light weight, convenient use and resistance. Corrosion and other characteristics, thickening non-woven fabrics because of good insulation effect, can also be used for multi-layer coverage.

The vegetable bed is covered with heat, moisture and seed germination. It can also fertilize, irrigate and spray on the bed. Not only is it convenient to use, but also the seedlings are strong and neat. Because its thermal insulation, air permeability and humidity control are superior to plastic film, its effect of covering seedling is better than that of plastic film. The specifications of non-woven fabrics are 20 grams per square metre, 30 grams, 40 grams, 50 grams and 100 grams, etc. the width is 2 meters to 8 meters, and there are 3 colors of white, black, silver grey. The specifications for bed covering are 20 grams or 30 grams of non-woven fabric per square metre, and white or silver grey in winter and spring. After sowing, the non-woven fabric with length and width larger than the border is directly covered on the bed surface. Because the non-woven fabric has certain scalability, the length and width must be greater than the length and width of the border. At both ends and sides of the border must be fixed, using soil or stone to compact the edge of the cloth, and can also be made of U shaped or T-shaped curved rods made of wire, fixed at a certain distance. According to weather conditions and vegetable production requirements, attention should be paid to timely exposing and covering.
