Based on an analysis of ecoclimatic applicability for millet, the climatic yield model was established in different climatic re-
gion. The key meteorological factors affecting yield were confirmed,which included≥10℃accumulated temperature, average temper-
ature from Aug to Sep, precipitation in July, altitude, the rate between investment and yield and so on.An integrated index system of
suitable planting division was given,and the eco-climatic planting division was divided into 5 grades.At the same time,the way to
enhance utilizing efficiency of ecoclimate resources was brought forward.
