摘要
在田间条件下,对20年树龄库尔勒香梨设置不同氮、磷、钾的施肥处理,用原子吸收光谱法测定香梨中7种矿质元素的含量。结果表明:库尔勒香梨果实中元素Ca、Mg、Fe、Na的含量相对较高,Zn、Cu、Mn的含量相对较低。与不施肥的处理相比,施肥能明显提高香梨Ca、Mg、Fe、Zn、Cu、Mn、Na的含量。香梨中Ca含量的施肥效应P>N>K,Mg、Fe、Zn、Cu含量的施肥效应N>K>P,Mn含量的施肥效应K>N>P,Na含量的施肥效应N>P>K。
Set different treatments of N,P,K for 20 years Korla fragrant pear in the field,and determines the contents of seven mineral elements in Korla fragrant pear by atomic absorption spectrometry （AAS）The results showed that the contents of Ca,Mg,Fe,Na in Korla fragrant pear were relatively high,but the contents of Zn,Cu,Mn were relatively low Compares with not to fertilize,it could improve the contents of Ca,Mg,Fe,Zn,Cu,Mn,Na in Korla fragrant pear to apply fertilizer in soil The role of fertilizer N,P and K to content of Ca was in order of P〉N〉K,the contents of Mg,Fe,Zn,Cu were in order of N〉K〉P,the content of Mn was in order of K〉N〉P,the content of Na was in order of N〉P〉K.
