| 摘 要： | 本文在大田条件下对不同施氮和灌溉处理下冬小麦数字图像的颜色特征进行了研究探讨。初步得出以下结论：充分灌溉条件下不同施肥处理间的色调值差异几乎持续到成熟期；而满足氮肥需求的条件下不同灌溉处理的色调值差异主要表现在灌浆后期至成熟期；数字图像能够反映冬小麦的生育时期。 |

| Abstract: | The color characteristics of digital image of winter wheat in field under different irrigation and N fertilization were studied.The results show that the hue differences between different N Fertilization under optimized irrigation nearly continue through the mature stage;while the hue differences between different irrigation under optimized N fertilization mainly occurs from grain filling to maturity;and the colour change of digital image can reflects the growing stage of winter wheat. |
| Keywords: | color characteristics digital image analyze winter wheat in field |
