摘要
连续4年的监测结果表明，贵州省荔波县引种的撑×绿杂交竹即撑绿竹竹林，在造林当年其竹笋的出土萌发经历了初期、盛期和末期3个阶段。6月为其出笋初期，出笋数占总出笋数的12．8％，7、8月为出笋盛期，出笋数占总出笋数的79．5％，9月为出笋末期，出笋数占总出笋数的7．7％。撑绿竹林经营至第3年，每丛竹平均有新竹1～9秆，其平均胸径为3．49cm，平均竹高6．2m，新竹胸径大于3cm小于等于4cm的株数占44．61％，此时竹林的结构达到最佳状态。
The growth of Bambusa pervariabilis × Dendrocalamopsis daii to Libo county of Guizhou province were studied by monitoring the bamboo planted in permanent sample plots for 4 years. In the current year of planting, the shoot emergence could be divided into 3 stages, namely initial period, flourishing period and terminal period. June is the initial period, July to August is the flourishing period and September is the terminal period. The percentages of number of shoot production of these three period are 12. 8 %, 79.5 % and 7.7 % respectively. Up to the third year, each cluster has 1 to 9 new bamboos, with the average DBH and height of 3.49 cm and 6.2 m respectively, 44. 61% of the new sprouted bamboos have the DBH 〉3 cm and≤4 cm, the stand achieves the optimum status.
