几种除草剂对小豆田杂草的防治效果及对产量的影响

[目的]筛选防治小豆田杂草的除草剂。[方法]采用小区试验研究5种除草剂组合对小豆的安全性和杂草的防效。[结果]5种不同除草剂组合对小豆田杂草均有防除作用,其中2号、4号、5号、6号处理的短期杂草防除效果好,均在90%以上,但5号和6号处理对小豆有显著药害作用。4号处理的杂草防效最好,为91.3%。4号处理的增产幅度最大,为29.4%。[结论]综合分析5种除草剂组合对小豆的安全性、小豆田杂草的防治效果和对小豆产量的影响,认为4号处理的除草剂组合最佳,既能有效防治小豆田间杂草,又能增加小豆产量。

Effects of different Herbicides on Weed Control and Yields of Adzuki Bean

[Objective]The aim was to screen out herbicides to control weed in adzuki bean yield. [Method]We examined the control effects of 5 different herbicide combinations on weed in adzuki bean field and their safety to adzuki bean. [Result]All the different herbicide combinations had the control effects. The good effects on short-term weed control were treatment 2, 4, 5, 6 and their effects could reach above 90%, but treatment 5 and 6 had significant phytotoxicity. Treatment 4 could largely increase the yield to 29.4%. [Conclusion]Comprehensively analyzing the safety, yields of adzuki bean and the control effects of 5 different herbicide combinations, it is suggested that the best herbicide combination was treatment 4. It could effectively prevent weeds in adzuki bean field and could also increase yields.
