摘要
本研究以聚乙烯为基质,添加光、环境降解材料、除草材料和其他助剂,经吸附、偶联、挤出反应、吹膜等工艺流程,研制出一种新型地膜。该地膜既具有普通地膜保墒、保温的特点,更具有除草效率高、降解彻底、使用安全的优点。田间应用:对小白菜、烟草、棉花等经济作物中的单子叶和双子叶杂草的防效达95%以上,并在60～100天内完全降解,有效防止了田间杂草对作物的危害和农田的白色污染。
This research regard the PE which add to the photo-environment degradable masterbatch herbicide and other additives,through adsorption couple extrusion and blow film etc. research and produce the new type of mulch. The mulch not olny have characteristic of the common mulch but also have advantage of the high weeding ratio and high degradable ratio and safe usage. Field application : The mulch weeds a economic cropper(cabbage tobacco cotton) ,the effect amounts to 95% above. the mulch degradated at 60-100day.Peventing the miscellaneous grass and white pollution in the farmland effectively.
