[目的]明确不同除草剂配方组合对水稻生长影响及杂草防除情况。通过比较杂草鲜质量、株防效与水稻产量,分析除草剂配方防除效果。[结果]试验田第1次封闭使用丙炔草酮+吡嘧磺隆、第2次封闭使用丁草胺+吡嘧磺隆对杂草防效最好,禾本科杂草和阔叶杂草株防效分别为83.3%、96.1%,鲜质量防效分别为86.1%、97.9%,显著高于对照。[结论]在寒地水稻种植地区,推荐使用除草剂组合第1次为丙炔草酮、吡嘧磺隆和第2次为吡嘧磺隆、丁草胺。
[Objective] The research aimed to clarify the effects of different herbicide combinations on rice growth and weed control. By comparing the fresh weed quality, plant control efficiency and rice yield, herbicidal formula control effect. [Result] The first closed trial of propargyl ketone + pyrazosulfuron ethyl in the experimental field was the best. The weeds with the second encapsulation of butachlor and pyrazosulfuron were the best, the weeds of weeds and broadleaf weeds The control effects were 83.3% and 96.1%, respectively. The fresh-quality control effects were 86.1% and 97.9% respectively, significantly higher than the control. [Conclusion] The first herbicide combination was propargyl ketone, pyrazosulfuron ethyl and the second was pyrazosulfuron ethyl and butachlor in the paddy rice planting areas in cold region.
