Aeolian sandy grassland area is the main geomorphic type in the north of Yulin. The ecological environment is fragile and the problem of desertification is serious, which needs to be controlled urgently. The introduction of herbs is considered to be an effective means to control the sandy beach area. In this paper, licorice was selected as the indicator crop, and the introduction performance of licorice under different treatments in Yulin Sandy Grassland was observed through field experiment. The results show that: (1) after treatment, the physical structure of aeolian sandy soil is effectively improved. Compared with the control, the moisture content, temperature and porosity of aeolian sandy soil increased in varying degrees, which were 31.62%, 5.12% and 5.26% respectively, and the soil bulk density decreased by 4.08%. (2) After treatment, the chemical structure of aeolian sandy soil was significantly improved, the electrical conductivity, soil organic matter and nutrients were significantly increased, which were 22.63%, 21.09% and 4.66% respectively, and the pH decreased by 2.51% compared with the control group. (3) The treatment group could effectively improve the plant height, rejuvenation rate and coverage of Glycyrrhiza uralensis by 14.95%, 29.79% and 41.40% respectively.
