我国八省大豆主要矿质元素含量分布及相关性研究

对我国不同地区９０个大豆样本８种元素含量分析结果表明，不同地区大豆元素含量有差异，某些元素含量变化并有一定的地理分布规律，东北地区大豆的Ｋ较高，黄淮海地区大豆含Ｃａ高，Ｚｎ和Ｐ的含量由北往南递增，有南高北低的变化趋势。８种元素含量顺序为Ｋ〉Ｐ〉Ｃａ〉Ｍｇ〉Ｆｅ〉Ｚｎ〉Ｍｎ〉Ｃｕ。各种元素含量水平与美国的数据基本接近。大豆中的Ｚｎ与Ｐ、Ｆｅ、Ｍｇ含量呈显著或极显著正相关，与Ｋ和Ｃａ呈极显著负相关。Ｍ

Studies on the Contents of Major Mineral Elements of Soybeans and Their Relationship in 8 Provinces of China

Testing and correlation analysis were conducted for the contents of major mineral elements(P, K, Ca, Mg, Fe, Mn, Zn, Cu) in 90 soybean varieties in 8 provinces of China. The results showed that the contents of major elements measured gave the following pattern: K >P>Ca>Mg>Fe>Zn>Mn>Cu. The average levels of these elements were close to the data reported in USA. There was apparent regional differences in element contents of soybean. K wes higher in northeast than in southern China. Both Zn and P showed the same tendency of being high in south China and low in northeast China. The content of Zn had a very significant positive correlation with that of P, Fe, Mn, Mg, and very significant negative correlation with that of K and Ca. Mg had a highly positive correlation with Mn.
