| Abstract: | We define different levels of drought years with ±0.5 times the standard deviation and ±1.5 times the standard deviation of average annual rainfall of corn.After analyzing the influence of drought years on the Corn production,we establish the corn meteorological production assessment equation through the analysis of meteorological conditions in maize growing period. |
