关黄柏特色药用经济林栽培试验初报

At the Beginning of Amur Corktree Bark Medicinal Economic Forest Characteristic Test

通过建立关黄柏栽培对比试验区,分别采用株行距为2 m×1.5 m、3 m×2 m和3 m×3 m三个处理方式,以及选择坡位上、中、下腹3个处理,开展关黄柏栽培的试验研究,每个处理3次重复。在各个重复内,逐株测量树高、胸径、冠幅3项调查因子,称取标准木单株栓皮量,据此测算出各处理间的平均树高、平均胸径、平均冠幅及单株栓皮量等指标,并进行比较分析。结果表明:采用株行距3 m×2 m的栽植密度,其林木单株栓皮量数值最大;营造关黄柏特色药用经济林的最适坡位应选择中、下腹。

Through the establishment of Phellodendron amurense comparative cultivation experiment area,respectively, the spacing is 2 m ×1.5 m、3 m×2 m、3 m×3 m three treatment and selection of slope, middle and lower abdomen three processing, 3 times each. Within each repetition by measuring tree height, diameter at breast height, crown breadth 3 survey factor, according to standard wooden cork showed, so as to measure the process between the average tree height, average diameter at breast height, average crown breadth and cork showed index, and comparative analysis. The results showed that the plant row spacing of 3 m ×2 m of planting density, its largest cork showed numerical trees, create Phellodendron amurense characteristic economic forest the optimum slope position should be selected, the lower abdomen.
