[目的]控制巴音布鲁克高寒草原轮叶马先蒿的大面积蔓延。[方法]对2006年和2007年2年的单种除草剂化学防除效果进行研究，并选择2，4-D丁酯和2甲4氯2种化学药剂对轮叶马先蒿进行对比试验。[结果]不同喷施时期、不同浓度对轮叶马先蒿的化学防治效果不同，两种药剂的最佳喷施时期均为盛花期;喷施2，4-D丁酯对禾本科杂草有一定的防治效果，而喷施其他药剂则相反。[结论] 2甲4氯是轮叶马先蒿化学防治的理想药剂。
【Objective】To control the wide spreading of Pedicularis verticillata in Bayanbulak alpine grassland.【Method】The result of the two years'(2006 and 2007) chemical control using single herbicides were studied,and two kinds of chemical(2,4-D butyl ester and MCPA) were chosen to control the Pedicularis verticillata for comparison test.【Result】It turned out that the effect of Pedicularis verticillata's chemical control was different at different spraying period and different concentration.The best time was full flowering stage when the two kinds of chemicals were sprayed.There was certain effect on grass family when 2,4-D butyl ester was sprayed,but the result was opposite to spray the other chemical.【Conclusion】MCPA was the ideal chemical for Pedicularis verticillata's chemical control.
