摘要
通过野外调查,分析了不同经营密度及竹龄对四方竹生长及笋产量的影响。研究结果表明,随着经营密度的升高,四方竹竹高及地径生长呈逐渐下降趋势;就笋产量指标而言,经营密度为1 400株/hm2的四方竹竹林出笋量最高,为合理的经营密度。在26年生四方竹竹林中,随着竹龄的升高,四方竹竹高、地径及出笋量呈逐渐升高的趋势。方差分析表明,不同经营密度对四方竹出笋量、平均竹高及平均地径的影响均达到极显著水平,不同竹龄对四方竹出笋量的影响均达到极显著水平。
The effects of different management densities and ages of bamboo on the growth and yield of Chimonbambusa quadrangularis Mak were analyzed in this paper through field investigation. The results showed that the height and ground diameter of C. quadrangularis Mak decreased with increasing the management densities; the highest yield of C. quadrangularis Mak was obtained when the management density of bamboo was 1 400 plants per hectare,and this was the optimum management density of bamboo. In the two to six aged of bamboo stands,a gradually increasing tendency for the height,ground diameter and yield of C. quadrangularis Mak were observed with increasing ages of bamboo. The analysis of variance showed that both of management densities and ages of bamboo have significantly influences on the height,ground diameter and yield of C. quadrangularis Mak.
