In order to analyze the effects of different intercropping patterns on the growth status, yield and quality of G. rigescens, six plant materials including Camellia sinensis (L.), Juglans regia L, Glycine max, Coix lacryma-jobi L., Glycine max (L.) merr and Vicia faba L. were selected to form seven crops patterns of G. rigescens monoculture and intercropping. Plant height, plant width, leaf length, leaf width and stem diameter of G. rigescens in vigorous growth period and harvest period were detected, fiber root number, root length, root diameter, gentiopicroside content were determined to explore the effects of different intercropping patterns on the yield and quality of G. rigescens. The results showed that the growth state of above ground part of G. rigescens intercropped with Juglans regia L. and Camellia sinensis (L.) was better than that of G. rigescens intercropped with Glycine max, Coix lacryma-jobi L., Glycine max (L.) merr and Vicia faba L. The intercropping with Juglans regia L. significantly promoted the growth of plant height of G. rigescens, while the intercropping with Camellia sinensis (L.) had large plant width, high leaf expansion and strong plants. The yield of G. rigescens in different intercropping cultivation was: Camellia sinensis (L.)>Juglans regia L.>Glycine max>Glycine max (L.) merr>control>Vicia faba L.>Coix lacryma-jobi L.. The yield of G. rigescens in intercropping with tea was the highest, 142.4 kg per hectare, 46.87% higher than that in the control. In different intercropping patterns, the number of fibrous roots of G. rigescens intercropping with Camellia sinensis (L.) was the highest, about 6-9 fibrous roots per plant, which was significantly higher than that of the control. The determination of gentiopicroside content in G. rigescens under different intercropping modes showed that: Camellia sinensis (L.) intercropping >Juglans regia L. intercropping>Vicia faba L. intercropping>Glycine max (L.) merr intercropping>Glycine max intercropping>control (monoculture)>Coix lacryma-jobi L. intercropping>Pharmacopoeia (1.5%), the gentiopicroside content in the roots and stems of Camellia sinensis (L.) intercropping was the highest, which was 3.36%±0.07%, significantly higher than that of the control and Coix lacryma-jobi L. intercropping intercropping. The correlation analysis showed that the root quality and yield of G. rigescens had a significant positive correlation with the aboveground plant width and leaf length, but had no significant correlation with the plant height of G. rigescens. The comprehensive score of the roots and stems by the membership function showed that the comprehensive quality of G. rigescens was better than that of the control: Camellia sinensis (L.) intercropping>Juglans regia L. intercropping>Vicia faba L. intercropping>Glycine max intercropping>Glycine max (L.) merr intercropping>control (monoculture)>Coix lacryma-jobi L. intercropping, Camellia sinensis (L.) intercropping, Juglans regia L intercropping, Vicia faba L. intercropping, Glycine max intercropping, Glycine max (L.) merr intercropping all higher than control, and the comprehensive score of intercropping Camellia sinensis (L.) was the highest, reaching 0.99.
