| 摘 要： | 该文对栗树苗期干物质累积以及氮、磷、钾吸收特性进行研究,结果表明:随着苗龄增加,栗树苗干物质累积总量明显增加;栗树苗期对N、P、K的吸收量为N>K>P,对N的吸收量明显高于对K、P的吸收量;对N、P、K的吸收比例为N∶P2O5∶K2O=5∶1∶1。

| Abstract: | The dry matter accumulation and Nitrogen （N）, Phosphorus （P）, Potassium （K） uptake characteristics in chesmut in a seed- ling stage were studied. The results showed that the dry matter accumulation increased significantly with the growth of seedlings. The uptake of N, P and K in chestnut seedling was ranged： N〉K〉P, the uptake of N was significantly higher than the uptake of P and K. The uptake ratio of N：P2O5：K2O by chestnut seedling was 5：1：1. |
