宝鸡苹果园土壤营养和理化性质研究

为掌握宝鸡地区苹果园土壤理化性质、养分状况，推广精准施肥。2021年6月，选择全市8个苹果基地县区56个苹果园，检测了理化性质和土壤养分共计16项指标。在检测结果的基础上，结合前人研究的土壤养分标准值进行对比分析，明确宝鸡市苹果园渭北和秦岭山地土壤肥力基本一致，限制性因子是pH值偏高，将来施肥重点是增施有机肥、土壤调理剂，进一步改良土壤、活化土壤。

Physical and Chemical Properties and Nutritional Status of Apple Orchard Soil in Baoji

The object of this study was to investigate the physical and chemical properties and nutrient status of apple orchard soil in Baoji area to promote precise fertilization. In June of 2021, 56 apple orchards in eight main apple-producing counties in Baoji were selected, and 16 indexes of physical and chemical properties and soil nutrients were analyzed. Results showed that the soil fertility of weibei orchards in Baoji and the Qinling Mountains was similar, with the limiting factor being the high PH value. Based on previous studies, the soil nutrient value met standard requirements. The future fertilization efforts should focus on adding organic fertilizers and soil conditioners to enhance the soil and pormote the soil activity.
