摘要
为了指导威宁红富士苹果合理施肥,对威宁红富士苹果叶片和果实的10种主要矿质元素含量进行了测定。结果表明,N、Mn和Fe含量明显高于正常值,4月份P和Cu含量高于正常值,5月份以后处于正常值范围,其余7种矿质元素含量均处于正常值范围,P和Cu含量比较高,B和Zn含量相对较低;成熟果实与叶片矿质元素含量呈现极显著正相关关系,5月份和8月份叶片矿质元素含量与成熟果实矿质元素含量相关性较高。
10 major mineral elements contents in leaves and fruits of Weining Red Fuji Apple were determined to guide the rational fertilization.The results showed that the contents of N,Mn and Fe were significantly higher than normal values,P and Cu contents were higher than normal values in April and were in the normal range after May.The contents of the other seven mineral elements were in the normal range,P and Cu contents were relatively high,B and Zn contents were relatively low.The contents of mature fruit and leaf mineral elements had a significant positive correlation,Especially there was a higher correlation coefficient in mineral elements contents between mature fruit and leaf.
