由于长期缺乏对草原毒害草的重视，少花蒺藜草在彰武县全县范围内扩散蔓延，并已发展到难以控制的局面，给草原生态生产环境带来极大影响。本文通过喷施乙草胺单剂和乙草胺同精喹禾灵、烟嘧磺隆、烯草酮混合的3种复配剂来研究其对少花蒺藜草的防除效果。结果表明：喷施乙草胺单剂及其3种复配剂乙草胺+精喹禾灵、乙草胺+烟嘧磺隆、乙草胺+烯草酮40 d对少花蒺藜草均有较好的防治效果，防治效果都在75%以上。说明喷施乙草胺土壤处理剂及其和茎叶处理剂的复配剂可作为防除少花蒺藜草的手段之一，这对于草原上入侵生物少花蒺藜草的安全、有效防除有着重要意义。

Because of the long-term lack of grassland poisonous grass attention, Cenchrus pauci-florus Benth. spread all over ZhangWu county ,and it was almost out of controlling, which had brought great influence to the grassland ecological environment. The herbicide acetochlor and its 3 mixtures with quizalofop-p-ethyl, nicosulfuron and clethodim were tested for measuring their con-trolling effects on C. pauciflorus. These treatments of acetochlor and its mixtures all had good performance with rates of 75% higher 40d after spraying . It was to say that spraying soil treat-ment agent acetochlor and its mixture with leaf treatment herbiside may be used as a means of man-agement on controlling Cenchrus pauciflorus,which has a positive meaning for comprehensive manage-ment effectly with no pollution on the biological invasion plant C. pauciflorus in the grassland.
