摘要： 为探明N、P、K肥对扁桃叶片中各矿质营养元素含量的影响，给新疆扁桃营养诊断平衡施肥技术提供理论参考依， 2009—2010连续2年在结果期扁桃园内萌芽前分别土施不同浓度梯度的N、P、K肥，在扁桃果实膨大期采集叶片，通过对其中N、P、K、Ca、Mg、B、Zn、Fe、Mn、Cu 10种矿质营养元素含量的测定分析。结果表明：土施N、P、K肥能分别提高叶片中相应元素的含量，其中N还促进P、B、Fe、Zn、Cu的吸收，但与K、Ca、Mn发生拮抗；P促进了N、K、Mg、Mn的吸收，但与Zn、Fe发生拮抗；K促进了B、Fe、Zn的吸收，但与N、P、Ca、Mg发生拮抗。土施不同浓度梯度N、P、K肥能显著或极显著提高扁桃叶片中N、P、K含量，且施用量和叶片吸收的元素含量间存在线性关系，而N、P、K肥对扁桃叶片中其他9种矿质元素含量分别形成促进和拮抗双重关系。

Abstract: For research the influence of mineral nutrient elements content of almond’s leaves on exogenous fertilizer of N, P and K, providing the theory of references for nutrition diagnosis of balanced fertilization technology in Xinjiang. The soil was fertilized by different concentration’s fertilizers of N, P and K in the almond garden which was in fruit during the budding period from 2009 to 2010. From the determination and analysis of ten kinds of mineral nutrient elements content (N, P, K, Ca, Mg, B, Zn, Fe, Mn and Cu). The results showed that exogenous fertilizer of N, P and K can improve the corresponding elements in the leaves. N can promote the absorption of P, B, Fe, Zn and Cu, but restrict the absorption of K, Ca and Mn. P can promote the absorption of N, K, Mg and Mn, but restrict the absorption of Zn and Fe. K can promote the absorption of B, Fe and Zn, but restrict the absorption of N, P, Ca and Mg. It can significant or extraordinary significant improve the corresponding element content of almond’s leaves after spraying different fertilizers of N, P and K. There was linear relationship between fertilized quantity and the absorbed elements content of leaves, and also the fertilizer of N, P and K formed to promote and restrict dual relationship for nine kinds of various mineral elements content of almond’s leaves.
