Mineral elements content,absoption proportion and requirement of Sophora alopecuroides L. at different stages were studied by ICP-AES technology. The results showed that (1) During mature period, the average proportion for N:K:Ca: Mg:P:Na was 11.91:8.27:7.54:1.02:1.00, and the average proportion for Fe:Zn:B:Cu:Mn was 28.91:2.12:1.40:1.18:1.00; (2) Mineral elements content of every part differs in each period, and stems at vegetative growth stage and seeds at mature period have the highest mineral elements content proportions of the whole plant which were about 45.6% and 36.7% respectively; (3) Sophora alopecuroides L. plants at vegetative growth stage have the largest fertilizer requirement, followed by the flowering period, and the smallest during pod period.
