摘　　要：为进一步比较普通草铵膦与精草铵膦的除草活性,明确同等药效下普通草铵膦与精草铵膦的用量比例,本试验采用室内盆钵法,比较了3种不同结构型10%草铵膦水剂(1#、3#为普通草铵膦、2#为精草铵膦)对马唐、狗尾草、稗草、牛筋草、鸭跖草、铁苋菜和空心莲子草7种靶标材料的除草活性。试验结果显示,3种药剂对各靶标杂草均有较好的防效,而2#药剂整体表现出更高的生物活性,对7种靶标杂草防效的ED_(90)值为60.55~628.55 mL/667 m^(2),而1#、3#药剂的ED_(90)值分别为74.02~621.44 mL/667 m^(2)和33.7~753.58 mL/667 m^(2)。综合考虑药剂对多个靶标的除草活性,对5~6种供试靶标杂草达到90%的防效,1#和3#普通草铵膦的用量分别为2#精草铵膦用量的1.37~1.47倍与1.23~1.47倍。In order to further compare the herbicidal activity of glufosinate-ammonium and glufosinate-P,three glufosinate 10%AS(1#,3#for glufosinate-ammonium,and 2#for glufosinate-P)were used on seven kinds of weeds,including Digitaria sanguinalis,Setaria viridis,Echinochloa crus-galli,Eleusine indica,Commelina communis,Acalypha australis and Alternanthera philoxeroides.The three kinds of glufosinate AS all had good control effects on the seven kinds of weeds,while the 2#glufosinate AS showed higher overall biological activity compared with that of 1#and 3#.The ED90 values of the 2#glufosinate AS against the seven kinds of weeds were 60.55-628.55 mL/667m^(2),while the ED_(90) values of 1#and 3#were 74.02-621.44 mL/667m^(2) and 33.76-753.58 mL/667m^(2),respectively.As herbicides should have good control effects on various weeds,to control 5-6 kinds of target weeds with 90%weed control effects,the dosage of 1#and 3#glufosinate-ammonium is 1.37-1.47 times and 1.23-1.47 times that of 2#glufosinate-P,respectively.
