据《中国农学通报》2014年第4期《外源N、P、K肥对扁桃叶片矿质营养元素含量的影响》(作者杨波等)报道,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据,2009—2010年连续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,对其中N、P、K、Ca、Mg、B、Zn、Fe、Mn、Cu等10种矿质营养元素含量进 According to “China Agronomy Bulletin” 2014 the fourth period “exogenous N, P, K fertilizer on the content of mineral nutrients in almond leaf” (the author Yang Bo, etc.) reported that in order to prove N, P, K fertilizer on almond leaves The content of mineral nutrients in Xinjiang almond nutrition diagnosis of balanced fertilization technology to provide a theoretical basis for reference, 2009-2010 for 2 consecutive years before fruiting in the fruiting period were planted in different concentrations of N, P, K fertilizer, The leaves were collected during the swelling period of Almond fruit, and the contents of 10 mineral nutrients such as N, P, K, Ca, Mg, B, Zn, Fe, Mn and Cu
