| Abstract: | The main target of the paper is exploiting the change of the maximum temperature during
midseason rice flowering period, and its impact on the yield of midseason rice. Based on
the statistical data on weather in 7 provinces during 15 years, the midseason rice
function models are built up, with temperature variables included. Our result shows that
the maximum temperatures during midseason rice flowering periods have increasing trend
with a substantial fluctuation, with great differences among regions. When the maximum
temperature is between 35℃ to 39℃, the average yield of midseason rice will not change
significantly, but if the maximum temperature is above 39℃, the average yield of mid-
season rice will decrease by 13 percent. |
