| By using winter wheat and maize in the loess plateau of eastern Gansu as investigating objects，this article brings forward the basic conception of growth potential，and proposes its impersonal definition．Furthermore，it analyzes the influential factors of growth status of the crops．Finally，the assessment index system of crop growth status is established for different periods of winter wheat and maize in eastern Gansu，which makes the crop growth assessment more quantified，simplified，convenient and accurate． |
