摘　　要：通过对麻竹笋用林立竹密度、施肥量、截梢、灌溉等技术的试验研究,结果表明4种措施对竹笋产量有显著影响,前三者与竹笋产量呈抛物线型关系,竹笋产量随立竹密度、施肥量、截梢增加呈现先上升后下降的趋势;竹笋产量与灌溉次数呈直线相关,竹笋产量随灌水间隔时间增长而减少。4种因素的影响程度大小依次为:施肥量、立竹密度、灌溉、截梢。提出高效培育麻竹笋用林的优化模式为:施肥量为1800kg/hm2,立竹密度为3600株/hm2,灌溉为发笋期连晴10d浇水1次,截梢是保留竹秆高4m为宜。This paper studied the technologies in terms of bamboo stand density, fertilization, pollarding and irrigation. The result showed that the 4 measures had remarkable effect on bamboo shoot yield. The former three measures had parabolic relation with bamboo shoot yield, which presented the trend of increasing and then decreasing with the increase of stand density, fertilization and pollarding, while bamboo shoot yield had rectilinear correlation with the times of irrigation, decreasing with the increase of irrigation interval. The effect of 4 factors on the yield in terms of degree followed： fertilization〉 site density〉irrigation〉 pollarding. Finally, it presented a optimized model for high effective cultivation ofDendrocalamus latittorus shoot stand, i.e. 1 800 kg/hm^2 for fertilizer, 3600 culms/hm^2 for site density, 1 time/10 d for iirrigation in sprouting time and 4 m kept for bamboo culm.
