历时10年对大径级毛竹林进行培育试验，结果表明：大径级毛竹林发笋率、成竹率和大径级新竹数量比对照竹林分别增加1.30倍、1.31倍和16.07倍，大径级新竹数量占成竹总株数平均值为62.8％；大径级毛竹林平均胸径和最大胸径分别为12.28 cm、17.03 cm，平均枝下高和最大枝下高分别为8.95 m、13.0 m，立竹密度平均达到4705株/hm2。大径级毛竹林中，产材量和各解析因子在一定范围内均随大径级毛竹比重的增大而不断增加，径级越大其增长幅度也越大。

The cultivation test in the large diameter bamboo forest was conducted for 10 years. The results showed that, the large diameter bamboo shoot rate,bamboo rate and the quantity of large diameter bamboo than the control of bamboo were increased 1.30 times,1.31 times and 16.07 times. The quantity of large diameter bamboo accounted for the total number of bamboo was 62.8%. The average diameter and maximum diameter of large diameter bamboo forest were 12.28 cm and 17.03 cm respectively,the average and maximum under branch height were 8.95 m and 13.0 m respectively, and the average standing bamboo density was 4 705 strains/hm2. In the large diameter of bamboo forest,the production materials and the analytic factor increased with increasing proportion of large diameter bamboo,the bigger the diameter the greater the growth rate.
