摘要
与传统耕作相比 ,管理措施中的保持耕作措施能减少农药随径流流失的量和增加淋溶量。本文分析了影响农药环境行为的机理 :提高土壤中有机质和水分含量可影响农药吸附性 ;提高入渗能力会增加农药淋溶量 ;
In general, conservative tillage can reduce pesticide loss from surface runoff and increase pesticide leaching, comparing to conventional tillage. Three effective mechanisms are analyzed in this paper: increasing the contents of the organic matter and moisture in soil will affect pesticide adsorption characteristics; improving infiltration will increase pesticide leaching; enhancing the efficiency of water and soil conservation will reduce surface runoff and pesticide loss.
