摘　　要：毛竹各器官执行不同的营养功能,造成养分浓度上的差异,养分浓度在不同种植年份的毛竹林中也存在着差异,林龄短的叶片氮含量高于林龄长的毛竹林,钙镁等移动性较差的营养元素,因移动性较差,有一定的累积效应,林龄长的含量高。Each organ of Phyllostachys edulis has its special nutrient contents for its different foundation. Meanwhile, there is a differential between the nutrient concentrations of Phyllostachys edulis forests in different years. The leaf of young bamboo has the higher nitrogen contents. The leaf of old bamboo has the higher contents such as Calcium and Magnesium for their characteristic of hardly moving.
