摘要：以绿竹笋用林优质高效培育为目标,林分结构因子组合处理为手段,研究表明:丛出笋数与立竹度呈抛物线形关系,与立竹胸径无相关;笋个体质量随丛立竹度增加而递减,立竹胸径则相反;丛竹笋经济产量与立竹度、立竹胸径符合四阶趋势面模型,与N/S比呈抛物线形;建立了丛立竹度7114～8694株/hm2,立竹胸径4～5cm,N/S比4.5～5.5,1～2龄立竹各占50%的丰产林分结构模式,模式增产效果显著,调控后第2年竹笋增产134.4%。提出了丛生竹散生状培育的研究方向。
With the aim at high shoot yield and quality of Dendrocalamopsis oldhami forest cultivation and with measuring mean of forest structure control through factors combination experimentation, the study is done with the results that the relation is parabola between the bamboo shooting number of cluster and the number of living stems (NLS), no notability with diameter at breast height (DBH); Bamboo shoot unit weight is descending following NLS's increasing, linearity increasing with DBH; The relation among bamboo cluster shoot output with NLS and DBH is following four rank direction face model; The relation is parabola between bamboo cluster shoot output and ratio of NLS to soil acreage of bamboo cluster (N/S); The fertility forest structure is NLS 7114～8694 per hm^2, DBH 4～5?cm, N/S 4.5～5.5, NLS years is 1～2 and account for 50%, respectively; Increasing effect of shoot output is notability by forest structure control, 134.4% increase in secondary year after control. The study direction in the future such as cluster bamboo to Monopodial cultivation for harvest most benefit is put forward, also.
