| 摘 要： | 分析了不同年龄苦竹Pleioblastus amarus 各器官的主要营养元素含量。结果表明:苦竹竹秆、竹枝和竹鞭中的氮、磷、钾元素含量随竹龄增大而减少, 硅元素含量随竹龄增大而增大;在苦竹不同器官中, 氮、磷、钾及硅元素含量以竹叶最高, 其次是竹枝和竹鞭, 竹秆最低;与毛竹 Phyllostachys pubescens 和光箨篌竹Ph .nidularia 相比, 苦竹竹秆、竹枝和竹叶的氮、钾、硅元素含量较高, 而磷元素含量相当。表6 参6

| Abstract: | Main nutrient elements in various organs of Pleioblastus amarus at different ages were analyzed .The results showed that the contents of N , P and K in the stem , branch and subterranean stem decreaseal with the increasing age ;the content of Si increased with the age .And the contents of N , P , K and Si in various organs were ranked as follows :leaf branch subterranean stem root stem .Compared with Phyllostachys pubescens and Ph .nidularia , the contents of N , K and Si in stem , branch and leavewere higher while the contents of P in three bamboos had no difference .
