不同牧草替代紫茎泽兰的效果分析

摘要

[目的]探讨不同有益牧草替代紫茎泽兰的效果.[方法]采用综合替代和直接替代2种替代方式,研究了7种优质无害牧草(皇竹草、象草、扁穗牛鞭草、串叶松香草、百喜草、香根草和扁豆)以及兔丝子替代紫茎泽兰的效果.[结果]综合措施有利于牧草替代紫茎泽兰,而直接替代除皇竹草、象草2个草种替代效果明显外,其他5个草种基本失败.[结论]为紫茎泽兰的有效防治提供了参考.%[Objective ] The aim was to explore biological substitution effects of Eupatorium adenophorum with different forage species. [ Method] Biological substitution effects of Eupatorium adenophonun with a Cuscuta species and seven kinds of forage species like Pennisetum hydridum, Pennisefum purpureum Schumach, Hemarthria compressa (Linn, f. ) R. Br, Silpnium perfoliatum L. , Paspalum nabatum, Vetiveria zizanioides linn. Nash and hyacinth bean were studied by two methods like comprehensive substitution and direct substitution. [ Result ] The comprehensive substitution method was helpful to control Eupatorium adenophorum, while direct substitution method was not good except that Pennisetum hydridum and Pennisefum purpureum showed obvious substitution control effects on Eupatorium adenophorum. [ Conclusion ] The research provides reference for the effective control of Eupatorium adenophorum.
