Farm nonwoven fabric is a better air permeability, moisture absorption, and a new translucent covering material. Agricultural sub-thin woven, thick and thicker type, usually expressed in grams per square meter name, such as 20 grams per square meter woven, 30 grams per square meter woven, non-woven 40 grams per square meter cloth, and so on. Agricultural nonwovens different thickness, water permeability, shading rate, ventilation rate differences, covering methods and uses are also different. Generally 20-30 g / m thin woven greater degree water permeability and ventilation, light weight, can be used in open field and greenhouse, greenhouse superficial coverage can also be used to reveal a small shed, greenhouse, greenhouse thermal screen, night from thermal effects, can increase the temperature 0.7 ~ 3.0 ℃. 40-50 grams / square meter greenhouse low permeable non-woven fabrics, shading rate larger, heavier quality, generally used as greenhouses, greenhouse thermal screen, but also can replace the cap in a small Pengwai straws, strengthen the role of insulation . Such non-woven fabrics are also suitable for greenhouses in summer and autumn shade nursery and cultivation. Thick non-woven (100 to 200 grams / square meter) instead of straws, grass thatch, together with greenhouse plastic sheeting, multi canopy coverage. According to the research, covering greenhouses covered with a woven straw mat significant than the insulation effect, but lighter than straws weight, easy to manage, is expected to be mechanized or semi-mechanized Uncovery. Woven in Japan, the United States, the Netherlands, Canada and other developed countries have already widely used. Our introduction of non-woven technology is not long, in-season vegetables cultivation development, agricultural nonwovens will be widely used.
