- Abstract: In order to investigate the content and distribution of available element in the rhizonsphere soil of the growing areas of Salvia miltiorrhiza Bunge, the contents of available element (N,P,K,B,Cu,Zn,Fe,Mn) in 26 soil samples were tested and evaluated. The results showed that the contents of available P and Fe were very plentiful, available K, Cu and Zn were rich, available N and Mn were deficient, available B was extremely deficient in all growing areas of S. miltiorrhiza of eight provinces in China. The correlation analysis showed that the contents of eight kinds of available elements were varying degree correlation. The stepwise regression analysis between the contents of available elements of rhizonsphere soil and ten kinds of active ingredients of Danshen (Salviae Miltiorrhizae Radix et Rhizoma) were researched. The results showed that the rates of contribution of available N,B,Mn and Fe to quality of Danshen were relatively large and they were the significant factors, and the other factors did not show statistical significance. The recommended fertilizing strategies is that the usage of N,B and Mn fertilizers should be controlled according to different stages of growth of S. miltiorrhiza, and P fertilizer should be reduced in all growing areas of S. miltiorrhiza.
