玉米是新疆自治区仅次于小麦的第二大粮食作物,近年面积稳定在53.3万hm2左右,玉米总播种面积占粮食总播种面积的28.6%,总产占粮食总产的36.1%,产量为粮食平均产量的1.36倍,是产量最高的粮食作物,也是我区发展畜牧业的基础。但是,我区玉米普遍使用乙草胺等封闭型除草剂进行播后和苗前土壤的处理,造成了效果降低、用药量加大,防治成本高,往往引起当茬及下茬作物的药害。同时,由于喷药质量差,喷洒的药液量不足,药液喷洒不到位,达不到理想的除草效果。为此,科学地选用除草剂品种是当前在玉米出苗前和出苗后防治杂杂草措施的关键。
Maize is the second largest grain crop in Xinjiang Autonomous Region second only to wheat. In recent years, its area has stabilized at 533,000 hm2. The total sown area of maize accounts for 28.6% of the total sown area of grain and its total output takes up 36.1% of the total grain output. The output is grain The average output of 1.36 times, is the highest yield of food crops, but also the development of animal husbandry in our zone basis. However, corn in our district generally uses closed herbicides such as acetochlor to sow the soil before and after sowing treatment, resulting in reduced effects, increased dosage and high prevention and control costs, which often cause phytotoxicity of stubble and next crop . At the same time, due to the poor quality of the spray, the amount of the sprayed solution is insufficient, the spray solution is not in place and the desired weeding effect can not be achieved. Therefore, the scientific selection of herbicide varieties is the key to the prevention and control of the weed plants before and after the emergence of corn.
