通过设置１４ 块标准地进行采脂试验研究，结果表明：马尾松采脂量与采脂树木的胸径、树高与树冠大小呈一元线性回归关系，其中采脂量与胸径相关关系极显著，在胸径为１６ｃｍ时，年采脂量为２－５６４ｋｇ ；根据我省马尾松资源现状，应贯彻以生产木材为主产品、生产松脂为副产品的经营原则；采脂树木胸径应不低于１６ｃｍ ，以下降式采脂方法为宜。
The results showed that there was a one-way linear regression relationship between the mass of Pinus massoniana and the diameter of tree trunk, the height of tree trunk and crown height. According to the current situation of masson pine resources in our province, the operating principle of producing wood-based products and producing turpentine as by-products should be implemented. The DBH diameter should not be less than 16cm Decline type liposuction method is appropriate.
