| 摘 要： | 本文使用数码相机获取黄金梨叶片图像并进行色彩分析，研究了利用数码图像技术进行黄金梨元素营养诊断的可行性，结果表明：黄金梨叶片的图像数字化指标绿光深度绝对值G与叶片全氮成显著性正相关；常规测试指标与钾的相关系数介于-0.703~0.923之间，R、G、B与镁含量呈显著或极显著负相关性；R、G与SPAD读数呈显著正相关。NRI与钾、锌分别成显著性负相关和极显著负相关；NGI和铁呈显著性正相关；NBI与钾、铁的相关系数分别为0.819**、-0.753*。数字图像分析技术在果业的可持续发展中将具有良好的应用发展前景。

| Abstract: | The most widely used methods to assess Whangkeumbae leaf nutrients status diagnosis and fertilization recommendation needs a lot of the laboratory for analysis.Due to their labor requirements or high costs these methods can hardly be applied.This study examined an alternative method to research the possibility of measuring leaf nutrients status diagnosis by using a digital camera to record the visible light reflected from Whangkeumbae.The results showed that greenness intensity had positive correlation with... |
