摘要：采用长期定位观测,定时、定株收获的方法,研究了马尾松胸径、树高、冠幅和年龄对产脂量的影响。结果表明:1)产脂量随着径级的增大而增加,二者呈正相关关系,不同年龄同径级产脂量差异不显著;2)产脂量随着树高的增大而增加;3)产脂量与各树体因子相关性分析得出:胸径>冠幅>树高>枝下高,相关系数分别为0.749、0.686、0.545和-0.147;4)产脂量随着年龄的增大而增加,且4种年龄的产脂量存在显著差异。
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 heig〉htheight 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.
