Abstract: For the problem of soil desertification caused by strong wind for long time and development of local grape industry in Yanhuai Basin,the influence of grasses on soil physical and chemical properties in the vineyards of Yanhuai Basin was determined,and the technology of planting grasses in vineyard was explored. Two kinds of grasses were selected for experiment and planted in 2017 according to the climatic conditions and characteristics of viticulture in Huailai County,and traditional cultivation as control. The physicochemical properties of sandy soil were analyzed after 3 years of planting. The results showed that:Compared with control,the nitrate content of 0-20 cm surface soil was increased significantly,and the available phosphorus,total nitrogen content of 0-80 cm soil layer was increased after planting Orychophragmus Violaceus (L.)O.E. Schulz for 3 years,while the physical properties of surface soil was improved.Compared with control,the organic matter and total nitrogen content of 0-20 cm surface soil was increased significantly after planting Carex lanceolata Boott. After 3 years of continuous cultivation,the contents of carbon and nitrogen in the aggregate of the surface soil were increased in vineyard.The influence of the two kinds of grasses on the aggregate structure of the sandy soil of the vineyard was different. The macroaggregate(>0.25 mm)content of surface soil was increased significantly after planting Carex lanceolata Boott and the microaggregate(<0.25 mm)content of surface soil was increased significantly after planting Orychophragmus Violaceus (L.)O.E. Schulz,so it was suggested that the surface soil should not be artificially ploughed after planting Orychophragmus Violaceus (L.)O.E. Schulz in order to prevent soil erosion in Yanhuai Basine. Soil physical and chemical properties could be improved and the effects on soil physical and chemical properties was different after planting grasses in vineyard,but the selection of suitable grass species was important in vineyard of Yanhuai Basin.
