In order to investigate the nutrient status of orchard soil in the main grape production areas of Shaanxi Province,the soil physical and chemical properties and nutritional components of grape orchards in the main production areas of Weinan,Xi'an,Xianyang and Baoji were measured,respectively,in the 0～20 cm,20～40 cm,and 40～60 cm soil layers.The results showed that in the main grape production areas of Shaanxi Province,the overall soil pH was strong alkaline,the soil had a large capacity,the soil was too tight,and the organic matter content was low.The nitrogen content was low,while the phosphorus and potassium content was high,and the content was unevenly distributed vertically and horizontally in the soil.Except for the increase of available nitrogen content with soil depth,total nitrogen,total phosphorus,total potassium,available phosphorus,and available potassium all decreased with soil depth.The content of Cu was abundant,while the content of Fe and Mn was lacking.Except for the rich content in the 0～20 cm soil layer,the content of Zn sharply decreased in the deeper two soil layers,in a state of deficiency.The content of Fe,Mn,Zn and Cu decreased with the increase of soil depth.
