| 摘 要： | 为了解施肥对川滇桤木苗期生长的影响,以1 a生川滇桤木幼苗为研究材料,通过施用不同量氮肥、磷肥、钾肥的正交组合施肥试验,测定其总叶绿素含量及光合速率的变化。结果表明,不同肥料配比对川滇桤木幼苗总叶绿素含量及光合速率有不同的影响,对叶绿素含量增加、净光合速率增大最适宜的氮磷钾肥比例为0~0.2∶0.6∶0.1~0.4。

| Abstract: | In order to investigate the effect of fertilization on the seedling growth of Alnus Cremastogyne,using one year old seedling of Alnus Cremastogyne as research object,the orthogonal and combinative test with three factors （nitrogen fertilizer,phosphate fertilizer,potash fertilizer） was made,the indexes change of tree seedling total chlorophyll content,photosynthetic physiology were determined.Results showed that the effect of fertilization on the seedling total chlorophyll content,photosynthetic physiology of Alnus Cremastogyne were different,the optimum combination for total chlorophyll content increased,the photosynthetic rate was shown to be N：P 0 ～0.2：1 ～0.4. |
