| Abstract: | In this study, a field experiment was conducted in Taigu County of Shanxi Province to study the variation of N ,P contents in different parts of Saphora japonica var. Pendula under different fertilizer treatments during a complete growth cycle. The results showed that the total trend of dynamic change of N ,P contents in Sophorajaponica var. Pendula was basically consistent, which was related with its growth cycle, an appropriate fertilization was better for Sophorajaponica var.
