| 摘 要： | 毛竹周年采伐是适应竹材加工业发展和市场经济的要求而提出的迫切要求解决的课题。伤流规律的研究是为周年采伐技术提供重要理论依据之一。通过测定分析表明:毛竹在1个生理周期内的伤流量呈两峰两谷分布,一般昼少夜多,降水会增加伤流量。伐桩上的伤流液主要来自鞭系,呈双向运输,以正向运输为主。伤流液营养成分含量因竹龄不同而差异显著,4度竹含量较低。挖笋也会产生伤流,从而引起养分损失。若仅从伤流养分损耗的角度考虑,以正常疏笋为养分损耗参照值,则1个毛竹生理周期中有16个月可以实施采伐。

| Abstract: | Study on regularity of bleeding caused by cutting of Phyllos-tachys pubescens throughout the year showed that in one physiological cycle, bleeding had two peaks and two bottoms.Generally, bleeding was more in the day, less at night. Rainfall could increase bleeding. Most of bleeding sap come from rhizome system with two ways of transportation dominated by positive one. Nutrient content in bleeding sap was different along with the age of bamboo. Shoot digging also could cause bleeding. The study resulted that Ph. pubescens could be cut 16 months in one physiological cycle. |
