摘　　要：氮在马铃薯生长发育过程中起着至关重要作用,氮肥的施用直接影响到马铃薯块茎的产量和品质。不同基因型马铃薯对氮肥的吸收、利用效率有显著差异。就氮效率的评价方法进行归纳,在对马铃薯氮素需求基础上,综述了马铃薯氮素效率评价方法的研究进展并进行展望,以期为不同氮效率基因型马铃薯的进一步研究和合理施用氮肥提供参考。Nitrogen plays a vital role in the process of potato growth and development.The application of nitrogen fertilizer directly affects the yield and quality of potato tubers.The uptake and utilization efficiency of nitrogen fertilizer for different genotypes of potatoes are significantly different.The evaluation methods of nitrogen efficiency were summarized.Based on the nitrogen demand of potato,the research progress in potato nitrogen efficiency evaluation methods was reviewed and prospected,in order to provide references for the further research of the different nitrogen efficiency genotypes of potatoes and the rational application of nitrogen fertilizer.
