马尾松(Pinus,massoniana Lamb)是我省主要采脂树种。它在自然界漫长发展过程中,经遗传,变异和自然选择的结果,在性状上发生了很大差异。长期从事采脂实践证实,在同样立地条件。同一林分里,相同起源、同样大小的马尾松、产脂力差异悬殊。为此,分析马尾松产脂力的调查方法和探究产脂力和采脂因子,松树形态性状间的关联性以及产脂力对松香松节油质
Massoniana Lamb (Pinus, Massoniana Lamb) is the main species in our province. It is in the long process of development of nature, by the results of genetic, mutation and natural selection, there has been a great difference in traits. Practice has long been engaged in the practice of collecting fat, in the same site conditions. The same forest, the same origin, the same size of Masson pine, fat production disparity. To this end, the analysis of Pinus massoniana fat production methods and to investigate the production of fat and fat factor, the correlation between the morphological characteristics of pine and fat production of rosin turpentine
