| 摘 要： | 应用MapInfo软件，建立了用于精确农业变量施肥的田间土壤养分信息数据库及田间施肥管理方式。根据土壤采样数据生成田间土壤养分分布图。依此可以了解田间土壤养分差异，并根据该差异进行变量施肥决策和变量施肥作业。应用实践表明：建立的田间土壤养分信息库可以应用于精确农业变量施肥的决策和作业管理。

| Abstract: | The software MapInfo was used to establish a soil nutrient information database and a management method of fertilization operation in the field for variable rate fertilization in precision agriculture. Soil nutrient maps of the cultivated land were made based on the soil sampling data. The difference of soil nutrient between operation units can be learned from the maps, and the decision and operation for variable rate fertilization can be made according to the difference. The results of the method showed that the soil nutrient information database on the field was suitable for variable rate fertilization decision and management in precision agriculture. |
