摘要
利用高粱芽培法,研究了增效剂对乙草胺(Acetochlor)在土壤中吸附性影响.结果表明,乙草胺的吸附性随土壤温度和土壤含水量的升高而减弱.阴离子表面活性剂、油类、Q7三类增效剂能显著降低乙草胺的吸附量,可减少1～1.5 mg·kg-1的吸附量.
Bioassay by bud incubation method shows the influence on the adsorption of acetochlor in soil. The experiment result showed the adsorption of acetochlor coefficients with temperature and humidity of soil. The amount of adsorption of acetochlor in soil was obviously reduced by adjuvant of anion superficial, oil, Q7. The amount of adsorption of acetochlor applied with adjuvant in soil was reduced by 1-1.50 mg·kg-1 .
