| 摘 要： | 以油松人工林针叶为研究对象,针对氮肥不同施用量对油松针叶内养分变化的影响进行研究。结果表明:油松针叶的有机碳含量和全钾含量随着氮肥施用量的增加而逐渐降低,而油松针叶中的全氮含量和全磷含量随着氮肥施用量的增加而逐渐升高,各处理间差异显著。

| Abstract: | This paper studied the influence of different application rate of nitrogen on Pinus tabuliformis needles nu-trients content change.The results showed that organic carbon content and total potassium content of P .tabulifor-mis needles of reduced gradually along with nitrogen increased,and total nitrogen content and total phosphorus con-tent in P .tabuliformis needles increased with nitrogen increased.The difference among groups was significant. |
