雷竹保护地栽培林分退化机制的初步研究

A Preliminary Study on Degenerative Mechanism of Phylloslachys praecor Stand Planted in a Protected Site

根据浙江省临安市高虹镇和东天目乡共４４个样地调查表明：因母竹留养困难，实施覆盖栽培不当等原因，雷竹林分出现退化．表现为雷竹立竹结构失调，幼壮龄鞭和鞭上侧芽数量显著减少，烂鞭严重，产量持续下降．

Based on the investigation of 44 plots selected in Gaohong and eastern Tianmu , Lin'an, Phylloslachys praecor was found to show degenerative symptoms due to poor nutrient holding capacity and incorrect implementation of mulching cultivation These symptoms included unfavorable stand structure, significant decline of young and mature bamboo rhizomes and their lateral buds, serious decay of rhizomes, and continuous decreased yields Strategy and suggestion were also provided in this paper to solve the above mentioned problems
