摘要
在赤水河下游选择经营制度、立地条件与林分质量相对一致的毛竹林,设置皆伐清理、皆伐清理炼山、超强采伐清理3种试验林,研究不同处理毛竹林生产力及生物量的差异。结果表明,皆伐清理与超强采伐清理毛竹林的出笋成竹量、新竹平均胸径及平均高度、新鞭质量和地上生长量均具有明显差异,皆伐清理中炼山和不炼山处理的指标间也有差异。3种处理新竹平均胸径和秆材量均小于生产性林分。
The Moso bamboo forest with the relatively uniform operational institution,site condition and forest quality in downstream of Chishui river Guizhou Province,China was selected to set up 3 treatments of clear cutting,clear cutting and controlled burning,ultra-intense cutting.The differences of productivity and biomass of Moso bamboo forest in different treatments were studied.The results showed that the developed bamboo rate,average DBH and average height of new bamboo,new rhizome quality and growth of above-ground of Moso bamboo forest in treatment of clear cutting were obviously different with those of Moso bamboo forest in treatment of ultra-intense cutting.The average DBH and culms amount of new bamboo in the 3 treatments were all smaller than those of productive forest.
