| 摘 要： | 以早实核桃辽宁1号和晚实核桃礼品1号为例，分别测定早实核桃和晚实核桃叶片中不同生育期N、P、K的含量，结果表明，核桃叶片中N、P、K含量在幼龄叶中最高，整个生育期内核桃叶片中N、P、K含量总体上呈逐渐降低。早实核桃的N、P含量比同期的晚实核桃高，且差异极显著；而K含量无差异。

Contents of N, P and K in leaves of Juglans regia and its annual dynamic rhythm |
| |
| Abstract: | Taking early fruiting Juglans regia No.1 Liaoning and late fruiting Juglans regia No.1 gift as examples, contents of N, P and K in leaves of different reproducing periods were determined, respectively.The results indicated that contents of N, P and K were highest in young leaves, and the contents showed a decreasing tendency gradually.Contents of N and P in early fruiting Juglans regia No.1 Liaoning were higher than that of late fruiting Juglans regia No.1 gift and the difference was significant.There was no difference regarding K contents. |

| Keywords: | Juglans regia leaf contents of N P and K changing rhythm |
