摘要
为筛选适合四川绵阳直播油菜田使用的除草剂,选择了7种除草剂进行田间试验,调查其对直播油菜田中杂草和油菜的影响。结果表明:精恶唑禾草灵和喹禾灵.胺苯磺隆.草除灵分别使油菜产量增加10.41%和0.83%,对双子叶杂草的防效分别为86.15%和92.42%,对单子叶杂草的防效分别为84.54和88.67%。
In order to screen out suitable herbicides used for local direct - seeding rapeseed field, we investigated the effects of seven kinds of herbicides on weed control and rapeseed growth in direct - seeding field through field tests. The results showed that applying Fenoxaprop - P - ethyl and Quizalofop - ethyloEthametsulflironoBenazolin - ethyl increased rapeseed yield by 10.41% , 0. 83% respectively, their control effects against dicotyledonous weeds were 86.15% , 92.42% respectively, and those against mono- cotyledonous weeds were 84.54%, 88.67% respectively.
