Rabdosia rubescens is a good wild herb with high economic value for medical use and soil and water conser-vation. Along with exploitation and utilization of rabdosia rubescens, its wild resource was increasingly in-sufficient. Experiment and analysis showed the feasibility of enlargement of artificial cultivation. The artifi-cial cultivated rabdosia rubescens was stable in hereditary character, and its biologic and ecologic character-istics and medical value were without obvious difference as compared with wild rabdosia rubescens. The arti-ficial cultivated technique used in the experiment can increase the rate of emergence of rabdosia rubescens seed from less than 1% by wild spreading to 87. 2% and increase the rooting rate of cutting by 90. 5%. Rabdosia rubescens has good effects in retaining water and preserving soil. The area growing annual rabdosia rubescens can reduce runoff and soil loss by 36.1% and 48. 5% respectively than contrast area, and by 18. 3% and 26. 8% respectively than the area growing annual honeysuckle.
