我国大豆主要矿质元素含量及其地区差异

Differentiation in contents of major mineral elements of soybeans from different regions in China

  • 摘要: 对我国不同地区9O个大豆样本9种元素含量分析结果表明, 同地区大豆元素含量有差异,某些元素含量变化具有一定的地理分布规律,黄淮海地区大豆Ca含量高,Zn和P含量由北向南递增,B含量北方高于南方。9种元素含量依次为K>P>Ca>Mg>Fe>Zn>Mn>B>Cu。大豆中Zn与P、Fe、Mg含量呈显著或极显著正相关,与K、Ca、B呈极显著负相关;Mg与Mn呈显著正相关;B与Ca呈极显著正相关,与Zn、P呈极显著负相关。

     

    Abstract: Contents of major mineral elements(P,K,Ca,Mg,Fe,Mn,Zn,Cu.B)in 90 soybean cultivars from different regions in China are analyzed.The results suggested that the contents of some elements changed from place to place and tended to follow some regulalions.Ca in the Huanghe-Huaihe-Haihe Plain held the highest content in the country.The contents of Zn and P decreased from south to north.On the other hand,the content of B in north part was higher than that in the sooth.The content of elements generally followed the pattern of K> P>Ca> Mg> Fe>Zn> Mn> B>Cu.The content of Zn was positively corre-lated with those of P,Fe,Mg and negatively correlated with those of K ,Ca.B both in very significant leve1.The content of Mg was positively correlated with that of Mn in a significant leve1.The content of B Was significantly correlated with that of Ca in a positive way and with those of Zn and B in a negative way.
