摘　　要：为更好地利用土地资源,于湖南省毛竹主产区桃江县林科所竹林中选择立地条件和林分结构基本一致的向天窝、蛇冲、屋后排等3个地段,分别于上、中、下坡位设置固定样地,采取不同坡位单位面积施肥量不同的施肥方法对毛竹笋材两用林进行施肥试验。结果表明:不同坡位的毛竹林,其新笋出土时间和平均出笋数量基本一致,各种坡位毛竹林的单笋平均质量、地径和新笋总质量差异不明显;坡位间立竹胸径及枝下高的差异均达显著,各种坡位毛竹林的立竹胸径及枝下高均呈现下坡>中坡>上坡的规律。通过对不同坡位的毛竹两用林控制施肥量,在施肥当年就已缓解了上、中、下坡竹笋产出的差异,达到了提高竹笋产量的目的。In order to make better use of land resources, taking there main growing area of bamboo forest in of Xiangtianwo, Shechong and Wuhoupai of Taojiang County in Hunan Province for fertilization experiment plots with the consistent forest site conditions and selection of stand structure. The fixed sample plots were set up in the upper, middle and lower slopes respectively, and the fertilization experiment was carried out with different fertilizer application methods of different slope unit area with Phyllostachys pubescens stand for shoot and timber products. The results show that： the new bamboo shoots time and the average number of shoots were similar at different slope positions, and there was no significant difference in the average quality, average diameter and the total quality of the new shoots. There was significant difference in the DBH and the height of the branches between the slope positions, and showed the rule lower 〉 middle 〉 upper slopes. By controlling the amount of fertilizer can balance the products of bamboo shoots in the different slope position, and increased the yield of bamboo shoots.
