**1. Introduction**

For thousands of years, Chinese medicinal herbs were collected from forested mountains, which faded away with the demands of human healthy [1]. People have to choose artificial cultivation in the field and adopted high-yield method for its planting. However, high-yield method betrayed the characteristic of medicinal herb, which caused medical effectiveness and quality to decrease deeply [2]. We explore a new road for medicinal herb cultivation under forest without chemical fertilizer and pesticide. It is based on the principle of biodiversity for pest control.
