【摘要】 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。更多还原

【Abstract】 Masson pine tapping is one of developing industries. Its research aimed to improve the level of oleoresin production and management in Henan province. The tapping test was done with 14 sample plots in the paper and the research result shows that the relation of the quantities of oleoresin collection among the tree height, tree d.b.h and tree-crown is the univaniate correlation of linear regression and the eorrelation between oleoresin production and tree d.b.h is extreme significance.The annual oleoresin productivity of tree d.b.h in 16cm is 2 54kg. On the basis of the resources situation of our provincal Masson Pine,the executive principle is dominant in gaining wood and subsidiary in gaining oleoresin.The tapping tree b.d.h is above 16cm,and the descending tapping method is good.更多还原
