自1978年以来,采取同一种源、同一造林实施方案,在浙江省建德、嵊县、余姚、奉化、临安等地营造了杉木檫树星状混交林约21ha(313亩),通过7年的连续测定,已初步得知:混交林的单位面积蓄积量明显大于檫树纯林,生态效益显著;尤以三行杉、一行杉檫隔株混交和二行杉、一行2杉1擦混交配置图式为佳。 Since 1978, the same source and plan of afforestation have been adopted. About 21ha (313 mu) of Fir plantation star-shaped mixed forest was set up in Jiande, Shengxian, Yuyao, Fenghua and Lin’an in Zhejiang Province. After 7 years Of the continuous determination, has been initially informed that: the unit area of ​​mixed forest was significantly larger than the volume of pure forest, with significant ecological benefits; especially in three rows of fir, Schematic configuration is better.
