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.

Key words: potato, nitrogen fertilizer, remote sensing, precision agriculture, nitrogen diagnosis
