Keyword:  田埂杂草苏家屯区药效非耕地杂草芦苇除水杂草覆盖度阔叶杂草植保站技术总结;
Abstract: 41%农达(Roundup)是美国孟山都公司生产的一种内吸传导灭生性望叶处理除草剂,防除一年生及二年生禾本科杂草、莎草科杂草及阔叶杂草和多年生深很杂草,适用于非耕地杂草的防除。根据农达的这一作用特性,我站将农达应用于水渠田埂杂草的防除,效果显著。由于老稻区受多方面因素的影响,水渠多年不易更换,导致水渠内外、田埂上杂草丛生,尤其是多年生杂草生长旺季,危害猖极.正值水田灌溉时期,严重降低水流速度,影响灌溉。同时造成病虫草害的传播蔓延,如果采取人工割草办法解决,每年需搞、三次,在目前分田至产的管理情况下,不易统一组织。示范地点安排在苏家屯区红菱镇、八一镇,主要杂草有芦苇、稗草、马唐、红寥、辣营、香蒲
