摘要
在系统整理金佛山方竹、筇竹等中小径笋用竹相关研究成果的基础上,结合云南省昭通市的实际情况,分析中小径笋用竹的特点和乔木对中小径笋用竹林的作用,总结了在营造中小径笋用竹林中乔木树种配置的原则和方法。中小径笋用竹林竹鞭分布较浅,常与乔木或灌木混生,较耐荫;在中小径笋用竹林中配置乔木,具有庇荫、增加土壤肥力、改善土壤结构、增加群落稳定性、提高竹林生物量等作用;选择乔木树种应遵循生长快、价值高、寿命长、深根性、喜光、以落叶乔木为主的原则,根据树种生物学特性、乔木层郁闭度并结合林分经营目的、经营水平选择合适的配置密度。为昭通市中小径笋用竹造林推荐了19个乔木树种,适宜的乔木种植密度为5~42株/667 m^(2)。
Based on the review of research results on small and medium-diameter bamboo such as Chimonobambusa utilis and Ch.tumidissinoda,and in view of the actual situation in Zhaotong city,Yunnan province,this paper analyzes the characteristics of small-and medium-diameter bamboo forests for shoot producing and the role of trees in the forests,and summarizes the principles and methods of tree species configuration in the forest.Small-and medium-diameter bamboo forests have shallow bamboo rhizomes,and higher more tolerance to shade,so they can be often mixed with trees or shrubs.Planting trees in small-and medium-diameter bamboo forests has the functions of providing shade,increasing soil fertility,improving soil structure,enhancing community stability,and increasing bamboo forest biomass.The selection of tree species should follow the principles of fast growth,high value,long lifespan,deep root,preference for light,and deciduous trees dominance.The appropriate configuration should be determined based on the biological characteristics of the tree species,canopy density of the tree layer,and the consideration of the purpose and the level of forest management.A total of 19 tree species are recommended for afforestation of smalls and medium-diameter bamboo forests for shoot producing in Zhaotong city,with a suitable planting density of 5-42 trees/667 m^(2).
