The analysis of dry matter accumulation and chemical constituents of Salvia miltiorrhiza under compound planting conditions
Abstract：In this study, analysis the dry matter accumulation and chemical composition of Salvia miltiorrhiza’s root in different compound planting conditions, and explore the allelopathic effect of different plants for the growth of Salvia to provide a theoretical reference on the establishment of Salvia’s ecological cultivation mode by setting up four ways of compound planting about Salvia respectively with Cassia tora Linn., Capsicum annuum L., Erilla frutescens (L.)Britt. and Zea mays Linn. The result showed that the compound planting of Capsicum and Salvia, Erilla and Salvia can promote growth of Salvia and improve yield of Salvia. In the compound planting of Erilla and Salvia ,the diameter of Salvia’s roots is 13.17mm and the fresh weight of Salvia’s root is 26.39g. The compound planting of Salvia and Capsicum can improve the content of the active components of Saliva, in this way the content of salvianolic acid B is 8.15%. The compound of Salvia and Erilla can reduce the content of active ingredient, in this way the content of tanshinone IIA, tanshinone I and cryptotanshinone can’t meet up to the requirements of Chinese Pharmacopoeia. The compound planting of Salvia and Cassia or Zea can’t improve the growth, yield and quality of Salvia miltiorrhiza. Conclusion: The compound planting of Salvia and Capsicum is the best cropping pattern in this study.
