退化毛竹林改建珍贵树种林造林试验

Afforestation Experiment on Improving Degraded Moso Bamboo Forest with Valuable Tree Species

近年来,由于毛竹林经营劳动力不足、经营水平低下、效益下滑等原因,致使浙江湖州一些毛竹产区出现许多因放弃管理而导致的退化毛竹林。将退化毛竹林改建为珍贵树种林基地是提高林地生产力、增加林农收入、实现林业可持续发展的有效途径。在安吉县报福镇汤口村,选取紫楠、黄山栾树、浙江樟、红豆树和榉树等5个珍贵树种对11.2 hm^(2)近6年无人管理的退化毛竹林进行改造,结果表明,经过4年抚育管理,各树种生长良好,对造林立地表现出较好的适应性,树高、胸径生长达到预期目标,退化毛竹林改造为珍贵树种林取得初步成功。研究结果为退化毛竹林改造成为高价值珍贵树种林提供了可借鉴的经验。

In recent years,many moso bamboo forests in Huzhou City,Zhejiang Province,has been abandoned and degraded,due to the lack of labor force,low management level and declined benefits.Afforesting the degraded moso bamboo forest with valuable tree species is an effective way to improve the productivity of forest land,increase the income of forest farmers and achieve the sustainable development of forestry.In Tangkou Village in Baofu Town of Anji County,five valuable species of Phoebe sheareri,Koelreuteria bipinnata‘Integrifoliola’,Cinnamomum chekiangense,Ormosia hosiei and Zelkova serrata are selected to afforest the 11.2 hm^(2)degraded moso bamboo forest that has failed to be managed for nearly 6 years.The results show that after 4 years of tending and management,all the precious trees grow well,with good adaptability to the forest sites,the growth of tree height and DBH reaches the expected goal,and the degraded moso bamboo forest has been preliminarily successfully improved into the valuable forest of valuable.The research results provide a reference for the transformation of degraded moso bamboo forest into high-value forest.
