| 摘 要： | 对以培育纤维材为目的日本落叶松幼林进行施肥5a的试验分析表明：肥效显著，施肥能有效促进幼林的地径、苗高和冠幅生长；肥效可延续至造林第5a；单施N肥效果比单施P、K及配比效果好；高剂量的P肥对幼林初期（2－3a)肥效不明显；基肥与追肥之间肥效无显著差异。 |

| Abstract: | The experiment of applying fertilizer five years to young Larix kaempferi with the purpose of producing fibre timber showed that basal diameter, tree height and crown width were obviously increased with manuring Larix kaempferi and the remarkable effect of fertilizers could last five years. But N fertilizer was more effective than P fertilizer, K fertilizer and the complex of N,P and K. The effect of high amount of P fertilizer was not remarkable in the young stage of Larix kaempteri . There was no obvious difference between base fertilizer and after manuring. |
| Keywords: | Larix kaempferi young plantation fibre timber fertilizer effect |
