摘要
针对黑龙江西部地区春播苜蓿苗期杂草危害严重的现状,采用单因素随机完全区组试验设计,探讨了13种除草剂组合处理对春播苜蓿田杂草防除的效果.结果显示,高效盖草能、精喹禾灵、稀禾定、苯达松+精喹禾灵4个处理防除单子叶杂草效果良好,杂草株防效大于94.49%;咪唑乙烟酸+苯达松、二甲四氯钠、苯达松、嗪草酮处理对阔叶类杂草效果显著,但是二甲四氯钠和嗪草酮对苜蓿有严重的药害,不能用于生产中;咪唑乙烟酸+苯达松、咪唑乙烟酸、咪唑乙烟酸+精喹禾灵、咪唑乙烟酸+稀禾定的杂草鲜重防效最好,在76.44%～84.08%.综合考虑株防效和鲜重防效以及本地区的杂草发生情况,咪唑乙烟酸+苯达松组合处理的效果较好,可在黑龙江西部地区苜蓿大田生产过程中推广利用.
Abstract
Aiming at the current situation of serious weed damage during the seedling stage of spring-seeded alfalfa in Heilongjiang Province,a one-way randomized group design was adopted to study the effects of 13 herbicide combination treatments on weed prevention and removal in spring-seeded alfalfa fields.The results showed that:the four treatments of Haloxytop-R-mithyl、Quizalofop-p-ethyl、Sethoxydim and Bentazone+Quizalofop-p-ethyl were effective in preventing monocotyledonous weeds,with the strain preventive effect greater than 94.49%;the treatments of Imazethapyr+Bentazone、MCPA-Na、Bentazone and Metribuzin were effective in preventing broadleaf weeds,but MCPA-Na and Metribuzin had serious chemical damage to clover and could not be used in the production;Imazethapyr+Bentazone,Imazethapyr,Imazethapyr+Quizalofop-p-ethyl,Imazethapyr+Sethoxydim are the best in preventing weeds with fresh weight,which were 76.44%～84.08%.Considering the control effect and fresh weight control effect as well as the occurrence of weed in this region,the combination of Imazethapyr+Bentazone had better effect,which can be promoted and utilized in the field production process of alfalfa in the western Heilongjiang Province.
