根据林木施肥模型 ,在毛竹主产区对材用毛竹林进行了大面积的施肥试验 ,结果表明 :按照该模型的基本步骤实施 ,立竹数中等 ( 2 30 0～ 2 60 0株·hm- 2 )的毛竹林平均每度(两年 )可实现增产 1 0 .61t·hm- 2 ,投入与产出比为 1 8.7;施用化肥在施肥后的两年内不能促进毛竹胸径的增长 ,但能使新生竹数增多 5 0 %左右 According to the forest fertilization model, a large area of ​​fertilization experiment was conducted on the bamboo plantation in the main producing area of ​​Moso bamboo. The results showed that according to the basic steps of the model, the average number of bamboo stand (2 30 0-2 60 0 plants · hm- 2) could increase productivity by 10.61t · hm-2 per hectare (two years), with a ratio of input to output of 8.78. The application of fertilizers could not promote the growth of bamboo DBH within two years after fertilization, The number of newborn bamboo increased by about 50%
