| 摘 要： | 对引自美国、以色列和伊朗的3个阿月浑子品种的成年树在生长过程中的叶片营养元素(N、P、K、Ca、Mg、Mn、Cu、Fe)质量分数进行测定分析,结果表明,3个阿月浑子品种叶片矿质营养元素质量分数季节变化规律一致,从5月到9月,随叶龄的增加,N质量分数逐渐下降,Ca、Mg、Mn、K质量分数逐渐递增,其中Ca增加3倍,最为明显,而P、Cu、Fe质量分数变化不显著;7月中下旬营养元素质量分数相对稳定,为阿月浑子营养诊断的最佳采样时期;试验地总盐量在0～20cm和20～40cm土层分别为666.6mg·kg-1和900mg·kg-1,为强碱性土壤,导致阿月浑子P、Fe亏缺,叶片缺素症状明显,由于灌溉水含盐量高达2670mg·kg-1,到坚果成熟期部分叶片盐害症状明显,叶片中的Cu质量分数相对较高,但未发现明显的Cu害症状;阿月浑子叶片各营养元素质量分数的相关分析表明,不同元素间存在一定的相关性,其中N和Ca质量分数存在极显著的负相关关系,Mg和Cu质量分数存在极显著的正相关关系。

| Abstract: | Changes of 8 mineral nutrient elements (including N,P,K,Ca,Mg,Mn,Cu,Fe) in the leaves in vegetative season of mature trees of 3 pistachio cultivars introduced from the United States,Israel and Iran were examined and analyzed. The results showed that the seasonal changing trends of leaf nutrient contents of 3 pistachio cultivars were similar. From May till September along with the age of leaves N content decreased gradually,Mg,Mn and K content increased gradually,Ca increased most by 3 times,P,Cu and Fe cont... |
