研究并分析了银杏种子中氮、磷、钾、钙、镁、锌、铁、锰等８种营养元素之间相互影响、相互作用的关系。结果表明，银杏种子中各种营养元素间存在显著的线性相关关系，相关系数均达到极显著水平，多元素间的加合效应大于单一元素的作用；不同营养元素两两间的相互作用各有其特点，氮与磷、钾、镁间相互促进，钙与钾呈正相关，而与氮、磷呈负相关；微量元素锌、铁相互促进，锰则妨碍对锌的吸收。
The relationship and interaction among eight nutrients of nitrogen, phosphorus, potassium, calcium, magnesium, zinc, iron and manganese in ginkgo seed were studied and analyzed. The results showed that there was a significant linear correlation between various nutrient elements in Ginkgo biloba seeds, the correlation coefficient reached a significant level, and the additive effect of multiple elements was greater than that of single element. The interaction between different nutrient elements had Its characteristics, nitrogen and phosphorus, potassium, magnesium promote each other, calcium and potassium were positively correlated, but with nitrogen and phosphorus was negatively correlated; trace elements zinc, iron mutual promotion, manganese is hindered zinc absorption.
