摘　　要：对我国不同地区90个大豆样本9种元素含量分析结果表明,不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。Contents of major mineral elements (P,K,Ca,Mg,Fe,Mn,Zn,Cu,B) in 90 soy-bean 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 regula-tions. 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 south. The content of elements generally followed the pattern of K>PCa>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 level. The content of Mg was positively correlated with that of Mn in a significant level. 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.
