摘　　要：为探究产量与矿质营养的关系,本研究以6个不同产量的吊干杏花芽为试材,采用凯氏定N蒸馏法、离子光谱仪法、原子吸收分光光度计法分别测定N、P、K、Ca、Mg、Zn、Fe元素的含量,分析产量和矿质营养之间的关系。研究发现N元素含量与产量的相关系数为0.45,P元素含量与产量的相关系数为0.07,K元素含量与产量的相关系数为0.62,Ca元素含量与产量的相关系数为0.09,Mg元素含量与产量的相关系数为0.49,Zn元素含量与产量的相关系数为0.29,Fe元素含量与产量的相关系数为0.33。K元素含量与N、P、Ca、Mg、Zn、Fe元素含量变化均呈正相关的相关性,Ca元素含量与N、P、K元素含量变化之间的相关性均不显著,N、P、K元素含量变化之间均为正相关。结果表明,吊干杏产量高时,P、K、Ca、Mg、Fe元素在吊干杏花芽内含量较高,N、Zn元素为2016年含量大于2015年的含量,说明产量高时,N、Zn元素含量较少,推测产量的大小可以决定矿质营养的含量。To explore the relationship between yield and mineral nutrition.The contents of N,P,K,Ca,Mg,Zn and Fe were determined by Kjeldahl N distillation,ion spectrometer and atomic absorption spectrophotometer with 6 hanging apricot flower buds with different yields as test materials,and the relationship between yield and mineral nutrition was analyzed.The correlation coefficient between N content and yield was 0.45,P content and yield was 0.07,K content and yield was 0.62,Ca content and yield was 0.09,Mg content and yield was 0.49.The correlation coefficient between Zn content and yield was 0.29,and the correlation coefficient between Fe content and yield was 0.33.There was a positive correlation between the content of element K and the change of element N,P,Ca,Mg,Zn and Fe,while there was no significant correlation between the content of element Ca and the change of element N,P and K,but there was a positive correlation between the content of element N,P and K.The contents of P,K,Ca,Mg and Fe in the flower buds of hanging apricot were higher when the yield was high,and the contents of N and Zn in 2016 were higher than those in 2015,indicating that the content of N and Zn was lower when the yield was high,so it can be said that the yield can determine the content of mineral nutrients.
