在虎头山马尾松采伐迹地,进行了营造杉木樟树混交林、纯林试验,经过11年的经营管理,其林木生长良好. 结果显示:杉木樟树混交林的林木生长量,比纯林的林木生长量显著良好,树高平均分别大3.56%、7.25%,胸径平均分别粗14.47%、15.26%,树冠平均分别大21.28%、77.78%,郁闭度平均分别大3.26%、2.15%,单株材积平均分别大31.58%、38.89%,每公顷蓄积量平均分别多22.14%、41.89%. 杉木樟树混交林的土壤肥力养分N、P、K,分别比杉木、樟树纯林的土壤肥力也明显提高.

In pinus massoniana cutover land on Tiger Mountain ,the article conducts an experiment that a mixed forest and pure forest of Chinese fir and camphor tree are tested .After 11 years of operation and management ,the forests grow well . The results show that the forest increment of mixed forest of Chinese fir and camphor tree is obviously larger than that of pure forest .The average tree height of mixed forest is taller than pure forest of Chinese fir and pinus massoniana by 3.56%and 7.25%respectively;the average DBH is coarser by 14.47%and 15.26%respectively;the average crown is larger by 21.28%and 77.78%respectively;the canopy density is larger by 3.26%and 2.15%respectively;the individual volume is larger by 31.58%and 38.89%respectively;the average per hectare volume is larger by 22.14%and 41.89%respective-ly.The soil fertility nutrient N,P,K of mixed forest is clearly higher than that of pure forest .
