摘要
采用室内生物测定方法,研究了二甲戊灵对杂草的毒力和对甘蓝的安全性。结果表明,播后苗前在148.37～165.69 g/hm2的剂量下,采用土壤喷雾法施用二甲戊灵,可有效抑制稗、马唐生长,鲜重抑制率达90%以上;对甘蓝的安全性测定结果表明,二甲戊灵在甘蓝播后苗前施药对甘蓝安全。
Greenhouse experiment was conducted to determine the herbicidal activity of pendimethalin. The results showed that the toxicity of pendimethalin with soil treatment was sensitive to Echinochloa crusgalli L. and Digitaria sanguinalis （Linn.） Scop. ; at the dosage of 148.37-165.69 g/hm^2 , the inhibition rate of fresh weight of the two weeds was over 90%. In addition, it was salty to Brassica oleracea L. var. capitata Linn. by the security of the herbicide with soil treatment.
