Abstract

Maize is the main grain crop in Midwestern Jilin province. It’s conducive to analyze the characteristics and the effects on maize of droughts. 9 stations were selected during 1960-2014 based on the crop water deficit index (CWDI) and drought grades. Results show that:(1) The district water deficit condition are the overall drought characteristics in study area. Serious spring drought occurred more frequently in the western region of China, and the autumn droughts in eastern region are more likely to occur. (2) there was a direct effect on maize yield by droughts in the north regions of all study area. Excepting the jointing-tasseling stages, the water deficit in the eastern region of the remaining three growing periods had little effect on maize yield.
