摘　　要：麦田杂草防除是目前小麦生产中的难点,通过试验对比出在不同处理方式下几种药剂的防治效果,对晚粳稻茬麦田杂草的防除具有重要意义。试验对6种除草剂及其复配防治小麦田杂草进行药效试验对比,以筛选出较为理想的防治药剂。试验结果表明,3个封闭处理药剂的防效总体高于3个茎叶处理药剂的防效,能够在春前有效降低麦田杂草基数,达到防除麦田杂草的目的,可以很好地解决晚粳稻茬麦田杂草的防除难点问题,减少后期用药风险和成本,适合大面积推广和应用。Weed control in wheat fields is a difficulty in wheat production at present. The control effects of several chemicals under different treatment method were compared through experiments, which was of great significance to weed control in late japonica rice stubble wheat fields. In this experiment, 6 kinds of herbicides and their combinations were tested and compared to control weeds in wheat fields in order to screen out more ideal control agents. The test results showed that the control effects of the three closed treatments were higher than that of the three stem and leaf treatments, which could effectively reduce the number of weeds in wheat fields before spring and achieve the goal of controlling weeds in wheat fields. It could well solve the difficult problems of controlling weeds in late japonica rice stubble wheat fields, reduce the risk and cost of later medication, and therefore, was suitable for large-scaled popularization and application.
