To protect the crops from affected by the spring and autumn frost ( Before this, has been using porous polyethylene film) 。 Agricultural non-woven fabric with polyethylene film ( Plastic) Has the following advantages compared to. 1) Chemical treatment of water and good permeability, 2) Good resistance to infrared radiation, guarantee the warm spring time is suitable for ventilation, to reduce risk to 'heat stroke' ( Nutrient-laden 'heat stroke', it is because the temperature is too high to tip the scorched, die, ultimately affect the quality of vegetables and production. ) 3) Due to the special structure of the agricultural nonwoven fabric, and improved the uniform infiltration of the wind. 4) The man who can protection such as insect parasites invade. Ventilation, to reduce risk to 'heat stroke' ( Nutrient-laden 'heat stroke', it is because the temperature is too high to tip the scorched, die, ultimately affect the quality of vegetables and production. 1) 2) Due to its permeability, can prevent the damage of crop growth 'condensation' role. 3) Due to the special structure of the agricultural nonwoven fabric, and improved the uniform infiltration of the wind. 4) The man who can protection such as insect parasites invade.
