摘　　要：2013—2014年在新疆昭苏县乌鲁空盖草原选用270 g/L三氯吡氧乙酸丁氧基乙酯·氯氨吡啶酸钾盐水乳剂和21%氯氨吡啶酸水剂不同浓度对草原毒草——天山假狼毒进行群落影响试验。研究结果表明,270 g/L三氯吡氧乙酸丁氧基乙酯·氯氨吡啶酸钾盐水乳剂和21%氯氨吡啶酸水剂不同浓度均对天山假狼毒群落生长产生影响,与使用浓度呈正相关;其中使用270 g/L三氯吡氧乙酸丁氧基乙酯·氯氨吡啶酸钾盐水乳剂6 000 m L/hm2明显抑制天山假狼毒群落正常生长,并且对禾本科牧草安全性较高,同时禾本科牧草数量和产草量明显增加,可作为防除天山假狼毒群落生长的化学药剂。The effect of different doses of triclopyr - butotyl ＋ aminopyralid - potassium 270 g/L EW and aminopyralid 21 % AS on the community of the poisonous weed Stelleropsis tianschanica in Ulu empty cover grassland of Zhaosu,Xin-jiang was studied from 2013 to 2014. The two herbicides influenced the growth of S. tianschanica community in a dose - dependent manner. Triclopyr - butotyl ＋ aminopyralid - potassium 270 g/L EW 6 000 mL/hm^2 inhibited the normal growth of S. tianschanica community with adequate selectivity to the gramineous pasture, dose - dependent increasing both its density and yield,making it a suitable chemical treatment for controlling the growth of S. tianschanica community in grasslands of Zhaosu,Xinjiang.
