马尾松产脂量与树体因子关系研究
Relationship between Resin Yield and Tree Factors of Pinus massoniana
摘要
Abstract
Based on long-term positioning observation,timing and individual plant harvest,influences of diameter class,tree height,crown width and age were studied on resin yield of Pinus massoniana.The results showed that 1) resin yield increased with the increase of diameter class,resin yield of different ages had no significant difference in similar diameter class;2) Resin yield increased with the increase of tree height;3)The correlation analysis indicated that the impacts of tree body factors on resin yield were in the order of diameter class ＞ crown width＞ tree height＞height under branch,with correlation coefficients of 0.749,0.686,0.545 and-0.147,respectively;4) Resin yield increased with the increase of tree age,and there were significant differences in resin yield among four age groups.关键词
