摘要
南亚松是一种产脂力很高的优良树种。15年生的树木已可用于采脂;经过多年采脂的树木其泌脂能力仍然旺盛;天然林和人工林的树木产脂力无多大差别,但在林木个体之间产脂力的差异则相当大;海南岛以3～11月采脂为宜,缩小割面有利于长期采脂;立地条件较好产脂力较高,因此,应选择高产脂力的南亚松,在立地条件较好的林地上营建长期采脂基地林。
Pinus latteri Mason is a pine tree species with high oleoresin productivity and can be used for tapping from the age of 15 years. It keeps high oleoresin productivity after the tree has been tapped for more than 20 years or inters its overmature period. There is little difference of oleoresin productivity between natural forests and artificial plantation, but it can differ greatly in oleoresin productivity between individual trees. Higher yields of oleoresin are found in sites of better conditions which should be chosen for rosin base forests. In Hainan Province, tapping should be carried out between March and November, and small notches should be cut for longer tapping.
