| 摘 要： | 研究了不同坡位、不同海拔等地形因子对黄甜竹(Acidosasa edulis)引种栽培的影响。结果表明:1)坡位对黄甜竹的造林成活率、发笋数及平均胸径均有显著影响,造林第2年发笋数和竹高生长显著增加;2)生长在下坡位的黄甜竹,竹林平均胸径和平均高最高,而生长在中坡位和上坡位的竹林各项生长指标相对较低;3)坡位对黄甜竹生物量分布的影响较大,黄甜竹各构件生物量分配大小排序为秆 > 枝 > 叶;4)随着海拔高度的上升造林成活率、当年新发笋数、第2年新发笋数呈减小的趋势,平均胸径、平均竹高、单株生物量呈增加趋势。试验结果可为西南地区黄甜竹营林和推广提供理论参考。

| Abstract: | In this paper, we studied the influences of different terrain factors such as slope positions and altitudes on the introduction and cultivation of Acidosasa edulis. The results showed that:(1) the slope position has the significant influences on the survival rate, shooting number and the average DBH of A. edulis, and the shoots number and culm height of the 2-year-old bamboo forest grow greatly; (2) A. edulis growing at the lower slope has the highest average DBH and height, and those growing at the middle and upper slope have the relatively low growth indicators; (3) Slope position has the relatively large influences on the biomass distribution of A. edulis, and the biomass distribution amount among its different parts could be ordered as culm > branch > leaf; (4) the survival rate of bamboo forest, the new shoot number and the shoot number in the 2nd year of A. edulis show the decreasing trend and the average DBH, average height and individual bamboo biomass increase as the altitude grows. The experiment results can provide theoretical references for A. edulis afforestation and promotion in the southwestern area. |
