摘　　要：连续两年的田间试验结果表明 ,40 %快灭灵干悬浮剂对我省麦田常见的阔叶杂草如猪殃殃 Galium aparine、荠菜 Capsella burapastoris、播娘蒿 Descurania sophina、田旋花 Convolvuhusarvensis等具有优异的防治效果 ,不仅杀草速度快 ,而且不受低温、干旱等条件的影响。适宜的使用剂量在以猪殃殃、荠菜、播娘蒿为主的麦田为 30 g/hm2 ;在以婆婆纳 Veronica didyma、野油菜 Brassica campestris、米瓦罐 Silene conoidea为主的麦田为 45 g/hm2 ;在以泽漆Euphorbia helioscopia、大巢菜 Vicia sativa、麦家公 L ithospermum arvense为主的麦田为 6 0 g/hm2。施药时间以小麦三叶期至返青期为宜 ,喷液量以 6 0 0 kg/hm2The experiments of applying affinity 40DF to prevent and control broadleaf weeds in wheat fields were conducted from 1998 to 2000.The results showed that affinity 40DF has excellent effects on the common broadleaf weeds such as Galium aparine,Capsella burapastoris, Descurania sophina and Convolvulus arvensis.Its effectiveness was hardly affected by weather or temperature.The feasible dosage was 30 grams per hectare when the main species of weeds were Gapium aparine, Capsella burapastoris, Descurania sophina,the dosage was 45 grams per hectare when the weeds were Veronica didyma, Brassica calpestris, Silene conoidea,and the dosage was 60 grams per hectare when the weeds were Euphorbia helioscopia, Vicia sativa, Lithospermum arvense .The appropriate period for spraying was from three leaf period of the wheat to the period when it turns green after winter.
