| Abstract: | Based on maize original output and typical growth period rainfall in Tieling area from 1980 to 2008,correlation between maize yield and rainfall was analyzed.Taking water requirement characteristics in every growth period of maize from agricultural department as reference,the rainfall critical period which effect maize yield was put forward,and the precipitation prediction model was established.Meanwhile the hydrological and meteorological factors influencing maize yield were analyzed,and some suggestions were put forward. |
