【摘要】 以氮素诊断技术发展为主线，系统地综述了马铃薯氮素诊断的研究进展，评述了国内外马铃薯氮素诊断方法研究及应用现状，比较了基于植株和土壤的氮素诊断方法的优势与不足，为马铃薯氮素精准管理研究和应用提供理论参考。构建低成本、空间覆盖全的氮素诊断体系，结合植株和土壤的氮素状态精准施氮是精准田间管理的有效手段。更多还原

【Abstract】 Based on the development law of nitrogen diagnosis technology,this paper systematically reviewed the research progress of potato nitrogen diagnosis,reviewed the research and application status of potato nitrogen diagnosis methods at home and abroad,and compared the advantages and disadvantages of nitrogen diagnosis methods based on plant and soil,so as to provide theoretical reference for the research and application of potato nitrogen precision management. At present,it is an effective means of precise field management to construct a low-cost,spatial coverage nitrogen diagnosis system and further combine the nitrogen status of plants and soil with precise nitrogen application.更多还原
