由中国国际科技促进会研制的草纤维农用地膜,已成功地进行了年产250吨的小型工业化试生产,并申报了国家专利。目前我国使用的聚乙烯农膜,虽能使农业增产,但其碎片残留在土壤中难以溶解,隔断了土壤毛细管作用,使农作物根系不能正常吸收水分和肥料,从而造成减产。据统计,连续5年使用聚乙烯地膜覆盖,小麦减产20%以上,棉花和花生减产30%-40%。并且破坏生态平衡。而使用草纤维农用地膜则无此弊端。
The grass fiber agricultural film developed by China International Science and Technology Promotion Association has successfully carried out small-scale industrialized trial production with an annual output of 250 tons and declared a national patent. At present, China’s use of polyethylene plastic sheeting, although the agriculture can increase production, but its debris in the soil is difficult to dissolve, cut off the role of the soil capillary, so that crop roots can not normally absorb moisture and fertilizers, resulting in reduced production. According to statistics, for five consecutive years, the use of polyethylene film mulching, wheat cut more than 20%, cotton and peanut 30% -40%. And destroy the ecological balance. The use of grass fiber agricultural film is no such drawbacks.
