【摘要】 1996年~1998年田间试验,在大豆田施用不同剂量的金豆(Jindou),12个月和24个月后播种小麦、玉米、油菜、甜菜、西瓜和白菜等作物。调查这些作物的生育和产量结果表明,小麦和玉米对土壤中残留金豆不敏感,在正常施药水平下(40~80g,ai/ha),施药后12个月和24个月播种小麦和玉米均能正常出苗和生长,对产量无明显影响。油菜、甜菜、西瓜和白菜对土壤中残留的金豆敏感性略高于小麦和玉米,在40和60 g ai/ha较低剂量下,施药后12个月和24个月播种,均能正常出苗,无明显药害症状,对产量亦无明显影响。在80和120g ai/ha较高剂量下,施药后12个月播种,对苗期生长有不同程度抑制,对产量有一定影响;施药后24个月后播种,对苗期生长和产量无明显影响。更多还原

【Abstract】 A trial on effect of imazamox residues in soil for 12 and 24 months on growth and yield of succeeding crops was conducted during 1996 to1998.Results showed that wheat and com were less sensitive to the herbicide residue in soil under regular dosages of 40 ~ 60 g/ha and their growth and yield were not affected by the residues in soil for 12 and 24 months.Rape,beet,water melon and Chinese cabbage were more sensitive than wheat and com.The crops grew normally when the chemical was applied at 40~ 60 g/ha 12 months ago.However,the growth of the crop was inhibited in some degree when it was applied at 80 ~ 120 g/ha 12 ago.Effect of imazamox residue on growth and yield of the crops disappeared in 24 months after application.更多还原
