摘要
在毛竹林内进行伐桩内施肥、开沟施肥、竹周围施肥的比较试验,结果显示,3种施肥方式均能增加竹林的出笋数,但3种施肥方式之间没有显著差异;在退笋率、成竹直径方面,3种施肥方式与对照相比都有显著差异,但3种施肥处理之间没有显著差异;伐桩施肥由于施肥量少、操作简单等因素,表现出较高的经济效益。
The comparison experiment between the stump fertilization,furrow fertilization and hole fertilization in Phyllostachys heterocycla var. pubescens forests showed that the three methods could increase the number of shooting of Ph. heterocycla var. pubescens without significant difference; the tree fertilization methods presented significant difference compared with the control group in terms of shoot degeneration rate and culm diameter,but no significant difference appeared for shoot degeneration rate between the three methods. The stump fertilization had higher economic benefits because of its easiness to operate.
