Problems solved by technology

After the GAP planting standard of Chinese herbal medicines was implemented on a trial basis, these fertilizers with a wide range of applications had problems such as high heavy metal content, unreasonable element ratios, and poor pertinence. Failure to meet the standards of national GAP and pharmaceutical companies, let alone international standards, has become an important factor affecting the modernization of traditional Chinese medicine

[0003] In order to overcome the existing problems of poor pertinence, high heavy metal content, unreasonable element ratio, and low active ingredient content of medicinal plants in existing fertilizers in planting Chinese herbal medicines, the present invention provides a special fertilizer for medicinal plants. In response to the demand for fertilizers during the growth of root and stem Chinese medicinal materials, flower and fruit Chinese medicinal materials, and whole herb Chinese medicinal materials, it can effectively control the residue of heavy metals in Chinese medicinal materials caused by fertilizer application and increase the content of active ingredients
