摘 要:贵州耕地肥力质量总体偏低,质量变异显著,农田养分循环不良;部分地区耕地健康质量问题严重。结合贵州的粮食安全,提出了建立贵州数字土壤与农田质量预警系统,应用养分精准管理理论实施养分分区管理技术,以及应用养分资源综合管理技术平衡养分供给等耕地土壤养分管理的一些新理念。The farmland fertility was totally lower with significant variation and bad nutrient circulation in soil quality and polluted seriously in some of farmland in Guizhou province. On the basis of analyzing the situation of Guizhou food security and the production potential of farmland, the new ideas were provided on nutrients management for farmland, such as implementing the techniques of regionalized nutrient management by means of the theory of nutrient precise management, balancing the nutrient supply in line with the integrated management technologies of nutrient resources, and establishing digital soil system and alarming system of farmland quality etc.
