| 摘 要： | 对栗树果实发育过程中氮、磷、钾含量变化进行了分析．结果表明：氮、磷、钾在雌花中含量最高．在9月总苞形成果实的过程中，氮素含量减少后又开始增加，此后随着果实的成熟而再次减少；磷在7月中旬雌花败落期间含量显著降低；钾一直呈略下降趋势，含量变化不明显。

| Abstract: | Analysis showed that in the various development phases of chestnuts N, P, K primarily existed in the female flowers. In the process of involucre formation in September, the content of N increased after a physiological decrease, and then decreased again as the nuts began to mature. The content of P remarkably dropped in mid July when the female flowers entered the shedding stage. The content of K demonstrated a gradually declining curve, but the change was only slight. |
