摘　　要：评价20%精草铵膦铵盐可溶液剂对非耕地杂草的防除效果。于杂草生长盛期采用茎叶喷雾法进行田间小区试验。试验药剂20%精草铵膦铵盐可溶液剂剂量为300~600 g a.i./hm^(2)时,对非耕地禾本科杂草和阔叶杂草均有较好的防效,药后20 d,总草株防效和鲜重防效分别为93.32%~97.69%、97.69%~99.53%;对照药剂20%精草铵膦铵盐可溶液剂在450 g a.i./hm^(2)剂量时的总草株防效和鲜重防效分别为95.14%、98.52%。20%精草铵膦铵盐可溶液剂可以有效防除非耕地杂草,推荐剂量300~600 g a.i./hm^(2)。This study aimed to evaluate the field efficacy of the test herbicide glufosinate-P-ammonium 20%soluble concentrate(SL)against weeds in non-cultivated land.A field trial was conducted at the peak growth period of weeds by the method of directive stem foliar spraying.The test herbicide glufosinate-P-ammonium 20%SL was effective in the control of grass weeds and broad-leaved weeds in non-cultivated land at 300-600 g a.i./ha,and the total plant quantity effect and fresh weight effect at 20 days after treatment were 93.32%-97.69%and 97.69%-99.53%,respectively.The total plant quantity control and fresh weight control effects of the control herbicide glufosinate-P-ammonium 20%SL at 450 g a.i./ha were 95.14%and 98.52%,respectively.Glufosinate-P-ammonium 20%SL can effectively control weeds in non-cultivated land,and the recommended dose is 300-600 g a.i./ha.
