摘　　要：针对麻竹笋用林因长期管护措施不到位而导致竹林退化、产笋能力下降、竹农经济效益受损的现状,通过采取扒土晒目、培土施肥、除蔸打萌、浅翻垦复、地膜覆盖等综合培育措施以及适当的密度控制对退化竹林进行修复。结果表明:通过加强培育管理和适当的密度控制,可以显著提高退化麻竹林的出笋率、单笋质量和笋产量;提高笋产量的适宜密度控制措施为:1年生竹株每丛留4株,2年生竹株每丛留2株,其余年龄的竹子全部采伐。In view of the fact that the inadequate long-term management and protection of the Dendrocalamus latiflorus shoot forest has led to the degradation of bamboo forest,the decline in shoot production capacity and the reduction of bamboo farmers’economic benefits,the study takes comprehensive cultivation measures,such as soil raking and drying,soil cultivation and fertilization,stump removal and sprouting,shallow soil turning for reclamation,plastic film mulching and appropriate density control,to restore the degraded D.latiflorus forest.The results show that the shooting rate,individual shoot quality and shoot yield of degraded D.latiflorus forest could be significantly improved by strengthening cultivation management and appropriate density control.The suitable density control measures to improve shoot yield are as follows:4 per cluster are kept for 1-year-old bamboo,2 per cluster is saved for 2-year-old bamboo,and all bamboos of other ages are cut.
