Abstract:In this paper, topsoil samples of 10 representative orchards in Wugong County, Shaanxi Province were collected, and pH, contents of organic matter, available nitrogen, phosphorus, and potassium were measured, soil fertility were assessed according to the grade standard of 2nd national soil survey, and finally the reference was provided for scientific fertilization of kiwifruit orchard. The results showed that soil pH was 7.52-8.54 with an average of 8.16, indicating the soils belong to weakly alkaline soil. The content of soil organic matter was 10.78- 26.73 g/kg with an average of 18.43 g/kg, only 25.1% of the soil samples reached the middle level, indicating most samples were short of soil organic matter. The content of soil available nitrogen was 47.60-254.16 mg/kg with an average of 138.69 mg/kg, available nitrogen content of 64.7% of soil samples was more than 120 mg/kg, while only 8.0% of soil samples was insufficient in available nitrogen content. Available phosphorus content was 11.01-292.10 mg/kg with an average of 59.22 mg/kg, 90.3% of soil samples reached the rich and above levels of available phosphorus content. Soil available potassium content was 32.81-458.20 mg/kg with an average of 190.92 mg/kg, soil samples with rich, moderate and low levels of available potassium accounted for 57.3%, 28.2% and 14.5% of the total soil samples, respectively. The spatial variations of soil pH and soil organic matter in the study area were relatively small, and the contents of available nitrogen, phosphorus, and potassium were relatively rich, but the spatial distribution was uneven. In the future soil and fertilizer management, it is recommended to adopt comprehensive measures to moderately reduce soil pH to meet the need of kiwifruit growth. In addition, it is advised to strengthen the input of organic fertilizer in order to increase the content of soil organic matter year by year, and control the application of nitrogen, phosphorus and potassium fertilizers to improve the utilization rate of fertilizers.
