Abstract

本发明属于一种农用除草地膜，是以塑料树脂为基料，将甲草胺和甲草嗪两种除草剂按一定比例混合后再与塑料树脂经高速搅拌机搅拌3～5分钟，混合均匀后溶融、挤出、吹塑而成。其含量：塑料树脂为96.8～99.2％，48％甲草胺乳油为0.5～2％，50％甲草嗪为0.3～1.2％。地膜中除草活性成分含量，甲草胺为37.5～150mg/m2，甲草嗪为22.4～89.6mg/m2。本发明可用于玉米、豆科和茄科蔬菜田，可扩大对杂草的杀草谱，提高田间除草效果。

Description

除草地膜
本发明属于一种农用除草地膜。
目前农用除草地膜加工方法有：一种是将除草剂活性成分与聚乙烯醇水溶液和助剂配成涂敷药液，采用喷涂或涂布的方法制成单层有药的双层地膜，这种膜厚度为0.012～0.14mm，成本比较高，而且药膜分正反面，覆用麻烦。另一种用除草剂的50％溶液和助剂配成母液后，再与塑料树脂共混吹塑而成，采用低溶度溶液影响药膜单位面积除草剂有效成分的含量，量少除草效果差，量大药膜物理机械性能不好。还有一种是母液和塑料树脂采用人工搅拌混合吹塑，这种共混方法很难使药料充分混匀，造成田间防效不稳定，并且对人的皮肤和眼睛有轻微刺激。
本发明的目的是提供一种除草地膜，将防除一年生禾本科杂草为主的甲草胺与防除一年生双子叶杂草为主的甲草嗪混合，以提高对禾本科和双子叶杂草的整体防效。
本发明以塑料树脂为基料，将甲草胺和甲草嗪两种除草剂按一定比例混合后，再与塑料树脂经高速搅拌机搅拌3～5分钟，混合均匀后溶融、挤出、吹塑而成。其含量：塑料树脂为96.8～99.2％，48％甲草胺乳油为0.5～2％，50％甲草嗪为0.3～1.2％。成品地膜中除草活性成分含量：甲草胺为37.5～150mg/m2，甲草嗪为22.4～89.6mg/m2。
本发明可应用于玉米、豆科和茄科蔬菜田，可扩大对杂草的杀草谱，提高田间除草效果。
本发明是这样实现的：首先将48％甲草胺乳油1.02kg与50％甲草嗪0.61kg混合，再与塑料树脂100kg经2000～4000转/分的高速搅拌机搅拌共混4分钟，混合均匀后，溶融、挤出、吹塑而成。吹塑制得地膜中除草活性成分含量，甲草胺为75mg/m2(有效成分为36mg/m2)，甲草嗪44.8mg/m2(有效成分为22.4mg/m2，)厚度为0.008mm。或者将48％甲草胺乳油1.1625kg与50％甲草嗪0.6944kg混合，再与塑料树脂100kg经高速搅拌机搅拌共混4分钟，混合均匀后，溶融、挤出、吹塑而成。吹塑制得地膜中除草活性成分含量：甲草胺为75mg/m2(有效成分为36mg/m2)，甲草嗪44.8mg/m2(有效成分为22.4mg/m2)，厚度为0.007mm。
