摘要
对闽南山地肉桂密度试验的研究结果表明:7 a生肉桂不同造林密度间的保存率、树高和胸径存在显著或极显著差异,各器官的单株生物量和林分生物量也差别较大,说明造林密度对肉桂产量的影响极其重要.根据试验结果,提出如下适宜的造林密度:如以收获枝叶提炼桂油和桂通为主要经营目标,主伐年龄5～6 a且不间伐的桂子林,适宜的造林密度为6 000株/hm2左右;如以兼收型为培育目标,主伐年龄8～10 a的,则适宜的初植密度为4 500～5 200株/hm2,且应根据林分长势、林木分化程度等因素,适时进行适量间伐,以期培育优质丰产的肉桂林.
The effects of plantation density on yeild for Cinnamamun cassia were studied in this paper, the age of stand studied was 7a. The results showed that among different densities of plantation, there were significant differences existing in traits such as survival ratio, DBH and height, and bigger differences existing also in biomass produciton of both individual and stand, these results indicated that the influence of planting density on yield of Cinnamamun cassia was remarkable. Therefore, the suitable planting densities for different purpose of management would be suggested as followed： 6000 tree/hm^2 for the purpose of harvesting branches, leaves and tree bark at 5～6a; and 4500～5200 for the purpose of harvesting both timber and branches, leaves and bark at 8～10a. Suitalbe thinning might help to improve its quality and production of Cinnamamun cassia.
