摘要
采用LLDPE和LDPE共混树脂,添加除草剂及加工助剂,经混炼造粒研制出功能性除草地膜专用料。覆膜应用试验表明,专用料吹制的地膜可有效地杀灭杂草,除草率达到85％以上。薄膜物理机械性能符合国家聚乙烯农用地膜标准。
The functional materials with weed killer for agricultural mulch film was prepared by adding weed killer and processing aid ets. into LLDPE/LDPE blend, then, extruding and pelletizing. The results of experiment and field application showed that mulch film made from the functional material had excellent mechanical and physical properties which met the requirements presented by GB -polyethylene mulch film for agricultural uses and could kill weeds effectively, the rate of killing weed was over eighty - five percent.
