Abstract：To achieve sustainable development of grape industry and promote extremely simplified ecological cultivation mode(NS),the influence of NS on the soil quality of vineyard was studied by taking the Italian Riesling vineyard of Junding Winery in Penglai District,Yantai City,Shandong Province as the research object.14 physical and chemical indexes such as water content,bulk density,total nitrogen,total phosphorus and total potassium content were measured,and the soil quality was analyzed by KMO and Bartlett sphericity test and principal component analysis.The results showed that soil water content,soil organic matter and total carbon content were significantly increased under NS compared with traditional cultivation mode(TS).The difference of total carbon content of NS increased with time,and was 25.97% higher than TS on average.The contents of available potassium,total potassium,ammonium nitrogen,total nitrogen,total phosphorus,and the activities of soil phosphatase and sucrase of NS were increased.Among them,the phosphatase activity was the most significantly different,reaching a peak in May,which was 2440.84% higher than TS.There was no significant change in catalase activity.The soil urease activity was inhibited,which was 35.53% lower than TS.The soil quality scores of NS and TS were 1.37 and-1.51,respectively through the modeling and calculation of the soil comprehensive evaluation model.Compared with the traditional cultivation mode,the simplified ecological cultivation mode can effectively improve the soil quality and physical and chemical properties of orchard.
