摘　　要：本文采集不同氮肥胁迫下多品种水稻的NDVI值和SPAD值,分析NDVI值与水稻品种、生长期、氮肥胁迫水平等因素的相关关系,建立了不同生长期的NDVI值与SPAD值的最佳回归模型。本文的研究成果可为建立水稻信息专家库及水稻在线施肥系统提供决策依据。In this paper,the NDVI and SPAD values of rice varieties under different nitrogen stress were collected,and the correlation between NDVI values and rice varieties,growth period and nitrogen stress level was analyzed.The best regression model between NDVI values and SPAD values at different growth stages was established.The results of this study can provide decision-making basis for the establishment of rice information expert database and rice on-line fertilization system.
