青海柴达木盆地麦田化学除草剂筛选与杂草综合控制

Screening of the Herbicide in Wheat Field and the Integrated Control of Woods in Chaidamu Basin of Qinghai Province

柴达木盆地是青海省主要的商品粮基地,由于长期以来粗放耕作,造成春小麦田以野燕麦、藜等杂草为主的农田杂草大面积危害,严重影响春小麦产量和品质。通过化学除草剂单剂和复配剂筛选,结合化学除草剂施用方法的改进,配合农艺措施,达到综合控制该地区麦田杂草的目的。

Qaidam basin is a major corranercial grain base in Qinghai province.Few people farmed a lot of field extensively for a long time. The weed：Ave-na fatua L.and Chenopodium album L.becanme major weeds hanmed the field widely,the yield and quality suffered severely.ln order to control the weeds in wheat field in this region synthetically, we have screened different herbicides and mixtures and improved the method of herbicide application combining with agronmy measure.
