为了筛选四川地区水稻旱直播田有效除草剂,本试验选用了噁唑酰草胺、氯氟吡氧乙酸、氟吡磺隆、双唑草腈、苄嘧磺隆、丁草胺和丁.苄复配剂进行防除杂草的筛选试验。结果表明,10%噁唑酰草胺乳油+20%氯氟吡氧乙酸乳油、1.8%双唑草腈水分散剂和35%丁.苄复配可湿性粉剂防除禾本科及阔叶类杂草总防效较好,30天总杂草的株防效和鲜重防效都达91%以上,并且对水稻苗安全性好,可在四川地区水稻旱直播田推广应用。
Abstract
To screen effective herbicides which are suitable for dry direct-seeding rice field in Sichuan, this experiment selected metamifop, fluroxypyr- meptyl, flucetosulfuron, pyraclonil, bensulfuron, butachlor and benzyl-butyl to screen effective herbicides, and through the investigation of weed species and quantity to studyhe weed control effect of the seven herbicides. The results showed that 10% metamifop+ 20% fluroxypyrmeptyl EC, 1.8% pyraclonil SP and 35% benzyl-butyl WP had a good control effect on the gramineous weeds and broadleaf weeds. At 30 days, the controlling effect reached above 91% for each plant and fresh weight. Fur hermore, they had better safety for rice seedling, and could be popularized and applied in dry directseeding rice field in Sichuan. Therefore, 10% metamifop+ 20% fluroxypyr-meptyl EC, 1.8% pyraclonil SP and
35% benzyl-butyl WP have wide prospect in dry direct-seeding rice field in Sichuan.
