毛竹林鞭竹系统——“竹树”研究

Study on Rhizome-culm System of Phyllostachys heterocycla——Bamboo-tree

根据毛竹生长发育规律及特性,结合靖安县实施部、省、县级毛竹项目的调查,研究了毛竹林的鞭竹系统—"竹树"的生长活动节律及其作用;明确了"竹树"的相关概念和毛竹林大、小年的划分标准;绘制了毛竹林大小年鞭竹系统(竹树)的生长活动节律图;阐述了毛竹林花年鞭竹系统和大、小年鞭竹系统在一定条件下会相互转化的观点;建议毛竹林经营管理应留养1～8年生竹鞭,禁伐1～5年生毛竹,择伐6～8年生毛竹,皆伐10年生(含10年)以上毛竹。

According to the gowth rhythm and characteristic of Ph.heterocycla, combine the investigations of Ph.heterocycla project that implemented by Jing＇ an county at ministry, province, county level. The growing rhythm and function of rhizome-culm system of Ph. heterocycla-bamboo-tree were studyed. The relative conceptsof bamboo-tree and dassified standard of the bumper year or shortfall year of Ph. heterocycla were defined. The growing rhythm picture d the bumper year or shortfall year rhizome-culm system of Ph. heterocycla was drew. The flower year rhizome-culm system and the bumper year or shortfall year rhizome-culm system of Ph. heterocycla can transformated mutually under certain condition. We suggest that it should leave 1-8 years rhizome-culm, prohibited cut 1-5 years bamboo, selectively log 6-8 years bamboo and clear cut above 10 years （including 10 years）bamboo for managing and administrating.
