摘要
为了进一步了解西安市耕地养分现状,加快西安地区精准农业发展,利用2006-2008年采集的样品数据和土地质量地球化学调查与评价数据管理与维护(应用)子系统,对西安市不同行政区耕地土壤中的N、P、K等指标开展土壤养分地球化学单指标及养分综合评价。阐明西安市耕地养分丰缺,为地区农业发展提供科学依据。
Abstract：In order to further understand the nutrient status of cultivated land in Xi＇an, we are speeding up the development of precision agriculture in Xi＇an area to use the sample data collected in 2006 -2008 years. In the land quality geochemical survey and evaluation data management and maintenance （application） subsystem, we will carry out soil N, P, K and other indexes in the cultivated land in different administrative areas of Xi＇an, including soil nutrient geochemistry single index and nutrient comprehensive evaluation. This paper expounds the abundance and deficiency of cultivated land in Xi＇an, and it provides scientific basis for regional agricultural development.
