| 摘 要： | 为筛选出适合甘肃省肃南牧区栽培草地主要杂草防除的除草剂,以栽培草地播前和苗后2个时期为试验地,选择2,4-滴丁酯乳油,40%磺草-莠去津和30%草甘膦水剂3种除草剂,开展5个不同剂量处理下的杂草防除试验。结果表明：栽培草地播前,30%草甘膦有效成分剂量为1.65L/hm^2时,对赖草防除效果达到了94.68%,同时对栽培草地的发芽和出苗都没有影响,是比较理想的播前除草剂。苗后2,4-滴丁酯乳油有效成分剂量为3.60L/hm^2时对以大蓟、叶蒿和藜为优势杂草的栽培草地防效较好,防效分别达78.92%,85.08%和95.83%。

| Abstract: | In order to screen out the suitable herbicides for controlling the main weeds in sowed pasture in Sunan,Gansu Province,3 herbicides（2,4-D butyl ester,atrazine and glyphosate）were selected with 5 doses to test the efficiency.The results showed that the best control efficiency （94.68%） could be reached with 1.65L/ha dose of glyphosate to treat the soil before sowing and forage germination and growth were not affected,so it was the ideal one.After seedling stage,2,4-D butyl ester showed a satisfied control efficiency to Cirsium japonicum,Artemisia leucophylla and Ceratoides spp.with dose of 3.60 L/ha and the control rates were78.92%,85.08% and 95.83%. |
