| 摘 要： | 根据密度对凹叶厚朴人工林生长、干材和树皮生物量的影响规律,试验得出凹叶厚朴在 、 类地的造林密度以2500株·hm-2左右为宜.依据不同密度控制方式对林分生长、成材过程、径级结构、出材量和树皮产量的影响程度,认为定向培育凹叶厚朴材药两用林,于12～15a间伐1～2次,目标树保留密度以1505株·hm-2左右较为适宜.以利于改善凹叶厚朴林分结构、促进干材和树皮的合理发育、有效地提高凹叶厚朴人工林的出材量和生产力.

Density Control of Difinite Direction Cultivation of Timber and Medical Use Magnolia officinalis var.biloba Rehd.et wils Plantation |
| |
| Abstract: | According to the influence of density on the growth,timber and bark biomass of Magnolia officinalis var.biloba plantation,the experiments show the density of 2 500 trees per hectare or so is suitable for Magnolia officinalis var.biloba plantation in site type of Ⅰ,Ⅱ.According to the effect degrees of different density on the growth,lumber process,size class distribution,timber yield and bark yield of Magnolia officinalis var.biloba plantation,the way to definite direction cultivation is determined,which mean the reasonable thinning time is 1~2 times during 12~15 years,and the density of target tree should be retained at 1 505 trees per hectare or so.Such management pattern can improve stand structure,promot well growth of timber and bark,increase the timber yield and productivity effectively. |
