钩梢对5年生毛竹竹材物理力学性质的影响
Influence of Obtruncation on Physical and Mechanical Properties of 5 Years Old Culms of Phyllostachys edulis
摘要
Abstract
As a kind of management, obtruncation, which is widely used in the northern area of Zhejiang province, can avoid or lessen snow disaster on bamboo plantation. In order to know the influence of obtruncation on physical and mechanical properties of 5 years old culms of Phyllostachys edulis, we compared the density, shrinkage, compressive strength parallel to grain, shear strength parallel to grain, tensile strength parallel to grain, tangential bending strength, and elastic modulus of the three parts (bottom, middle and top) of culms, obtruncated and not obtruncated. Results showed that there was no significant difference of physical and mechanical properties between the two types of culms, while great difference exists in different parts of the two types of culms, which indicated that the management of obtruncation had no significant impact on the physical and mechanical properties of culms.关键词
