我区麦田化学除草已有多年应用的历史。据自治区农业厅于1980年的不完全统计,全灌区约有60％的麦田使用2—4D丁酯防除阔叶杂草,效果达90％。对野燕麦的防除,经多年试验,筛选出燕麦敌一号、燕麦畏、青燕灵、新燕灵等有效除草剂,肯定了燕麦灵加柴油有提高防除效果的作用。然而,上述各种除草剂,除2—4D丁酯在生产上得到大面积推广外,其它药剂或因系进口产品药源无保证,或因成本偏高,或因使用技术性强,未能广泛应
Our area of wheat field chemical weeding has many years of history. According to incomplete statistics of the autonomous region’s agriculture department in 1980, about 60% of the wheat fields in the whole irrigation area use 2-4D butyl esters to control broadleaf weeds, with the effect of 90%. On the control of wild oats, after years of experiments, we have screened out effective oats such as Oats One, Ophiopogon, Qingyanling and Xinyanling, and confirmed that oatmeal plus diesel has the effect of improving the control effect. However, all kinds of herbicides mentioned above, except that 2-4D butyl ester has been widely promoted in production, are not widely available due to the non-guarantee of the drug source of other drugs or imported products due to high cost or high technical use should
