摘　　要：红壤和冲积土上不同春大豆品种各器官和全株养分含量的分析结果显示:(1)初花期大豆根、茎、叶中的N,P,K及Ca含量和吸收量,红壤高于冲积土,而根、茎、叶中的Al含量和吸收量则相反;(2)不同春大豆品种各器官和全株的养分吸收量在红壤和冲积土上均有显著性差异;(3)大豆各器官中的养分吸收量通常叶最高,根次之,茎最低;(4)红壤中,浙春2号和乌皮青仁植株P吸收量高而Al吸收量低。The analytical results of nutrient content in different organs and whole plant for different spring soybean varieties grown on red soil and alluvial soil showed that (1) the contents and uptake amounts of N, P, K and Ca in roots, stems, and leaves as well as whole plants on alluvial soil were greater than those on red soil, but the contents and uptake amounts of Al in the organs were opposite; (2) the differences of uptake amounts of N, P, K ,Ca and Al in roots, stems, and leaves as well as whole plants between red soil and alluvial soil were significant difference; (3) uptake amount of the nutrient in organs of the plant was generally in order of leaves> roots >stems; (4)the varieties of high uptake amount in P and low uptake amount in Al were Zhechun 2 and Wupiqingren in red soil.
