ABSTRACT
Andrographis paniculata is a traditional Chinese herbal medicine with a wide cultivation in south China. The market demand has been increasing steadily in recent years. However, there are problems such as disordered production, pesticide residues and heavy metal content in the process of Andrographis paniculata production. Pollution- free cultivation is an effective strategy to solve this problem, and it is also the development direction of the Chinese herbal medicine planting industry at this stage. In order to guide the cultivation of pollution-free and high-quality Andrographis paniculata, this study established a pollution- free fine cultivation technology system of Andrographis paniculata including precise cultivation and site selection. In addition, soil improvement, scientific pollution-free planting mode and high- efficiency integrated pest control technology help solve problems such as pesticide residues and heavy metal content. This paper provides a reference for the pollution-free and fine cultivation of Andrographis paniculata.
