摘要
江苏省苏南地区，冬季麦田每公顷施用１５ｇ绿磺隆（以有效成份计，下同），翌年水稻栽秧时土壤中绿磺隆的残留量为０．２２μｇ／ｋｇ，种麦期间绿磺隆在土壤中的降解量约占施用量的９６．８％，绿磺隆在土壤中的降解半衰期平均为３８．６ｄ。水稻对绿磺隆也有高度的敏感性，由于绿磺隆在渍水土镶中容易降解，所以它在稻麦轮作地区对后茬水稻的实际危害较轻。改善土壤肥力状况，在一定程度上可减缓绿磺隆对作物的危害。
g AI/hm￣2 chiorsulfuron was applied to winterWheat field in sou then areas of Jiangsu province,The chlorsul-furon residue in soil was 0.22 μg/kg at the rice transplanting mo-ment in the next yea, 96 8 % of applied chlorsulfuron was de-graded during the wheat growing period, and the degradationhalf-life of chlorsulfuron in soil was 38.6 d.Like wheat , rice ishighly sensitive to chlorsulfuron As of chlorsulfuron is easily de-graded in flooded soil the actual damage of chIorsulfuron to rotaterice is light,and the improving of soil fertility to some extent mayaffiliate the effects of chlorsulfuron to plant.
