轮伐期、立竹度与光箨篌竹林生产力关系的研究

STUDY ON RELATION OF ROTATION CYCLE DENSITY WITH STAND PRODUCTIVITY OF PHYLLOSTACHYS NIDULARIA

采用大样（0.07hm2）套小作方（8m2）的办法,对轮伐期（A）、立竹度（B）在3个水平上进行裂区设计、5重复处理,对光箨篌竹林走向培育的1年生产量、竹林采伐量和现有林分的结构动态变化进行了分析,并用株数、平均眉径、眉径断面积、秆材量和生物量5个指标进行评判结果看出,A1B2是光箨篌竹林定向培育的最佳模式,如果强调现有林分质量的提高,则A1B1～A1B2为最适模式。

Evaluation with culm amount average D. E. H.,cross-section area of D. E. H.pole welght and blomass after split design on rotation cycle (A) and density (B) with 3 classes 、 5 repeat treatment, analysis on orientation cultivation l-year bamboo yield,bamboo cutting and dynamic change of forest structure showed that A1B2 was the best model for Ph. nidularia forest orientation cultivation.
