在福建省尤溪县西滨镇彩洋村,对大小年明显的毛竹林实施大年强度采伐、定量留养、控制新竹数量,合理施肥,小年留笋养竹等技术措施。实施5 a后结果表明:改善了竹林的生长条件和竹林结构。竹林密度增加84.8%,立竹平均胸径从8.6 cm提高到10.1 cm,竹笋产量增加18.9%。竹材产量增加47.8%。Ⅲ度以下的青壮竹占全林竹的75.6%,Ⅳ度以上老竹从试验前27%下降到24.4%,小年竹占立竹总数的43.8%,每年林地孕笋竹和换叶竹的数量达到相近,完成了大小年转变到花年毛竹林的改造。
In Caiyang Village, Xibin Town, Youxi County, Fujian Province, technical measures such as annual intensity harvesting, quantitative keeping, controlling the quantity of Hsinchu, applying fertilizers reasonably and keeping bamboo shoots in a small year were carried out on the moso bamboo forests with obvious size. After 5 years of implementation, the results showed that the bamboo growing conditions and the structure of bamboo forest were improved. The density of bamboo forest increased 84.8%, the average diameter of standing bamboo increased from 8.6 cm to 10.1 cm, and the bamboo shoot yield increased by 18.9%. Bamboo production increased by 47.8%. Young bamboo below Ⅲ degree accounted for 75.6% of the whole forest bamboo, Ⅳ above the old bamboo from 27% before the test down to 24.4%, small bamboo accounted for 43.8% of the total number of standing bamboo, annual bamboo shoots and bamboo leaves replacement The number reached a similar, completed the size of the year to transform the flower bamboo forest transformation.
