摘要 对4和5年生杉木幼林套种三年桐林分的生长效应、树冠和生物量结构、营养空间利用进行研究的结果表明:杉木幼林套种三年桐不仅促进杉木生长,而且也有利于三年桐的生长发育;通过套种三年桐,林分可提早1~2年郁闭,提高光能和土壤营养空间利用率;4和5年生套种林分的总生物量分别为纯林的1.26和1.61倍. In this paper,the growth effect,structure of tree crown and biomass,nutrition space utilization of ground and underground of Chinese fir interplanted with tung oil tree at the age 4 and 5 have been studied.The results showed that both Chinese fir and tung oil tree grew better through interplanting that the pattern stand could be closing 1-2 years ahead of pure forest and raise the utilization rate of light energy and soil nutrient,and that the total biomass of interplanted forest stand at the age of 4 and 5 was 1. 59 and 1. 92 times that of pure forest,respectively,and the Chinese fir biomass in interplanted pattern was 1.26 and 1. 61 times that of pure forest,respectively.
