摘　　要：为探明石竹立竹度对其出笋量的影响,采用随机区组设计,于土壤、坡度、坡位、坡向、施肥、抚育以及病虫害防治等条件基本一致的石竹林分中测定4种不同立竹度处理的石竹林的出笋量,采用单因素方差分析和多重比较进行显著性检验。结果表明,不同的立竹度对出笋量的影响达到极显著水平,以7500株/hm^(2)立竹度的石竹林出笋量为最高,出笋量达2225 kg/hm^(2)。建议在生产经营实践中合理调控立竹度,达到石竹林出笋量的稳产高产。In order to find out the effect of living bamboo density on shoot yield of Phyllostachy snuda,the randomized block design method was used to determine shoot yield of P.snuda stands treated with 4 different living bamboo density in the same condition of soil,slope,slope position,slope direction,fertilization,tending and pest control,and the significance was tested by one-way ANOVA and multiple comparison.The results showed that the shoot yield of different living bamboo density was significantly different,and the highest shoot yield was 7500 plants/hm^(2),the shoot yield was 2225 kg/hm^(2).This paper suggested to reasonably regulate the living bamboo density to achieve the stable and high shoot yield of Phyllostachys nuda.
