Experimental Study on Ecological Restoration of Glycyrrhiza Uralensis in Yulin Sandy Grassland

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