Abstract

Based on daily precipitation data, maize growth and yield data for the period 1981-2009 at 12 meteorological stations in Jilin. Then the Standardized Precipitation Index(SPI) and Mann-Kendall test were used to study the drought disaster during different growing period of corn. The results showed that the maize during the phase of tasseling and maturity tend to dry in Jilin. Drought happened more and more frequently, especially in northeast Jilin Province. Drought happen in stage of tasseling and maturity resulted in severe effects on maize yield. In every growth stage severe drought and extreme drought had more remarkable influences on maize yield than others. The present study provides some scientific technicalÿguidelines for drought resistance of maize in Jilin Province.
