【摘要】 目的:筛选安全有效的芸豆田茎叶除草剂类型。方法:采用田间试验方法,研究5种茎叶除草剂防除芸豆田杂草的效果及产量影响。结果:苗后茎叶除草剂48%氟乐灵处理、10%精喹禾灵、烯草酮和56%2甲4氯钠盐对芸豆田野黍、藜、狗尾草等杂草均有较好的防治效果,并能提高芸豆产量。其中,48%氟乐灵处理对芸豆田杂草防效最好,防效达95.7%;产量达1231.5 kg/hm~2,比对照增产80.9%。结论:芸豆田苗后茎叶除草剂防治效果最显著的是48%氟乐灵。更多还原

【Abstract】 [Aims]The safe and effective herbicides on the stems and leaves of Phaseolus Vulgaris were selected.[Methods]Field experiments were conducted to study the effects of 5 kinds of stem and leaf herbicides on weed control and yield of kidney bean field.[Results]The treatments of 48% TRIFLURALIN,10% quizalofop-p-ethyl,enolone and 56% 2 methyl-4-chloro-sodium had good control effects on weeds in field of Phaseolus Vulgaris,chenopodium album and Setaria Viridis,and increased the yield of Phaseolus vulgaris. The control effect of 48% trifluralin on weeds in Phaseolus vulgaris field was the best,the control effect was 95.7%,the yield was 1231.5 kg/HM2,and the yield was 80.9% higher than that of the control.[Conclusions]The most significant control effect of the stem and leaf herbicide was 48% trifluralin.更多还原
