摘　　要：佯黄竹(Bambusa changningensis)因其发笋量大、竹材产量高、材质好等优点,在四川省乐山市大面积推广种植。然而,佯黄竹在幼林生长阶段,林地杂草生长旺盛,直接影响了佯黄竹的成活率、发笋量和竹材产量,迫切需要寻找适宜的除草方式。文章基于乐山市佯黄竹林区除草的实践经验,结合佯黄竹及林下杂草生长情况,探讨了人工除草、机械除草、除草剂除草、覆盖控草、以草治草和动物除草等除草方式的效率和成本,以期为佯黄竹林的高效培育提供参考。佯黄竹林适宜的除草时间为4—5月份和9—10月份,在各种除草方式中,除草剂除草、植物残体控草是较优的除草方式,人工除草和机械除草次之,防草布控草、以草治草和动物除草仍在探索阶段,是有潜力的新型除草方式。Bambusa changningensis has been widely promoted and planted in Leshan city,Sichuan province,because of its advantages such as large quantity of shoots,high bamboo timber yield and a good material performance.However,in the young forests which are at the growing state,widespread weeds directly affect the survival rate,the number of shoots and the timber yield of B.changningensis.It is therefore urgent to find a suitable weeding method.Based on the weeding practices in the distribution area of B.changningensis forests,the paper discusses the efficiencies and costs of manual weeding,mechanical weeding,herbicide weeding,mulching for weeds control,weed control with grass and animal weeding in view of the growth of B.changningensis and understory weeds,in order to provide a reference for the efficient cultivation of B.changningensis forest.The suitable time to clear weeds in B.changningensis forests is in April or May and in September or October,and among the various weeding methods,herbicide weeding and mulching for weeds control are the best weeding method,followed by manual weeding and mechanical weeding while anti-weed cloth,weed control with grass and animal weeding are still at the exploration stage,which are the new weeding methods with potentials.
