| 摘 要： | 本试验采用室外盆栽的方法,研究了不同N、P、K肥处理对3年生早实核桃辽宁1号、晚实核桃清香的影响。通过对盆栽核桃幼树叶片、根系和枝条的N、P、K含量和叶片中叶绿素含量的比较分析。试验结果表明:(1)核桃品种间对N、P、K的吸收差异不显著;(2)叶片中N、K含量最高,根系P含量最高;(3)核桃幼苗施NPK肥均衡效果为佳。

| Abstract: | The outdoor potted planting were adopted for the experiment to study the effect of nitrogen (N), phosphorous (P) and potass (K) fertilizers on the three-year old walnut. Comparative analysis of the N, P, K in the leaves, roots and shoots of the pot-planted walnuts showed that . (1) the differences of N, P and K absorption among the varieties are not significant;(2) N and K in the leaf is higher in content while P in the root is in highest content;(3) for young walnut trees, the optimum effect comes from the balanced application of N,P and K fertilizers. |
