摘　　要：田间作物最重要的特征指标就是叶色,其能够直观地反映出叶绿素含量的变化、作物生长过程中的光合作用、养分情况及水分含量等栽培信息,为田间的作物管理、苗的生长情况的诊断和根据苗的肥力情况提供重要依据。以大豆的叶片为研究材料,测定了叶片的叶绿素含量,利用数字图像处理技术提取了叶片的颜色特征值。结果表明,叶绿素含量与颜色特征参数具有一定的相关性,并建立了与叶绿素之间的联系。The leaf color is one of most important features of field crops. It can intuitively reflect the changes of chlorophyll content, photosynthesis and nutrients, moisture content in the process of growing crops. It provides an important basis for the management of field crop, diagnosis of the growth of seedlings and the fertility of seedlings. The leaves of soybean were used to determine the leaf chlorophyll content with chlorophyll meter. The results showed that the chlorophyll content and color feature was correlated and the relationship between them was constructed.
