【摘要】 分析了不同年龄苦竹Pleioblastusamarus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Phyllostachyspubescens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更多还原

【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 leave were higher while the contents of P in three bamboos had no difference.更多还原
