Statistic classification of winter wheat growth conditions by using NOAA satellite information

The situations of crop growth is a very important reference in guiding agricultural production and forcasting crop yield.ln this study,value of green degree from meteorological sattellite is used for analysing the growth conditions of winter wheat in Huaibei.Firstly,based on the investigations to the growth situations of winter wheat and their distributions in Haibei from 1986 to 1994,four hypothesises were set up.Secondly based on the analysis of the historical green degree information,green degree indexes were presented for classification of three kinds of growth conditions.Thus the green degree information from meteorological sattellite can be used for monitoring the growth of winter wheat.
