毛竹纸浆林分类栽培及效果研究

The Effect of Silvicultural Management on the Production of Moso Bamboo Plantations for Pulp-making

  • 摘要: 通过浙江安吉、福建邵武、江西奉新三地统一进行的毛竹纸浆试验林研究,并在安吉建立20hm2毛竹纸浆丰产模式示范林,表明毛竹纸浆林的生产力水平主要取决于立地条件和科学经营管理。经营水平不同,毛竹纸浆林的生产力呈显着差异;立地条件和竹林生长状况不同,毛竹产量亦呈显着差异。该研究还提出了因地制宜、分类经营纸浆毛竹林的经营模式,即Ⅰ类林地,采用集约经营措施,度产新竹30~40t·hm-2的丰产模式;在Ⅱ类林地采用集约经营措施或中等集约经营措施,度产新竹20~25

     

    Abstract: A series of tests for pulp-making in the moso bamboo stands were conducted systematically in Anji Couny of Zhejiang Province,Shaowu County of Fujian Province and Fengxin County of Jiangxi Province,and practice was put into by establishing 20 hm2 high-yield model stand of moso bamboo for pulp-making. The results show that the productivity of moso bamboo stands are decided by habitat and scientific management,and has sighificant difference due to different management,site quality or different original bamboo stands state. A bamboo forest which is in an undesirable state in poor site can be guided toward the establishment of an ideal of normal state with technical measures such as loosing soil, fertilization,reasonable cutting,adjusting stands structure and so on.This paper also put forward the management model of moso bamboo stands for pulp-making by suiting measures to local conditions and classifying management to improve the economic effect,i.e.it is desirable model to take A measure of intensive management in class I site for 30~40 t·hm-2 high yield culms per on-and off-year,A or B measure of intensive management in class Ⅱ site for about 25 t·hm-2 moderate yield culms and C measure in class Ⅲ site for about 18 t·hm-2 yield culms.
