我国是世界上产竹最多的国家之一,现有竹林总面积达五千多万亩,其中,毛竹林占70%左右。毛竹具有生长快、成材早、产量高、用途广,竹林经济效益好的特点。在生产中,由于管理水平的不同,毛竹林的生产水平很不平衡,管理好的第一类竹林,年亩产量可达1500kg 以上,管理差的第三类竹林,年亩产量仅有100～150kg,单产相差10倍以上。我国现有的3600多万亩毛竹林,70%以上属于粗放经营的第三类竹林,结构不
China is one of the countries with the largest bamboo production in the world. The existing total area of bamboo forests amounts to more than 50 million mu, of which, bamboo forests account for about 70%. Bamboo has fast growth, early timber, high yield, wide use, good economic benefits of bamboo. In production, due to different management levels, the production level of bamboo groves is very uneven. The first-type bamboo forests under management have an annual output of more than 1,500 kg per mu and the third-type bamboo forests with poor management have an annual mu yield of only 100 ~ 150kg, yield difference of more than 10 times. China’s existing more than 3600 acres of bamboo forest, more than 70% belong to the extensive management of the third category of bamboo, the structure is not
