The ten-day change of meteorological factors from different regions of Hubei Province since 1981 and its effects on growing stage change of mid-season rice were analyzed,which was based on meteorological data including growing stage of mid-season rice,average temperature,the average maximum temperature,the average minimum temperature,the sunshine duration and the rainfall from 1981 to 2008 taken from national basic meteorological observation stations of Hubei Province including five regions as Wuhan,Suizhou,Lichuan,Zhongxiang and Gucheng with complete observation data of mid-season rice.The results showed that the average temperature,the average maximum temperature and the average minimum temperature exhibited an increasing tendency in the vegetative growth of mid-season rice.The average maximum temperature exhibited an increasing tendency in the reproductive growth,but the average temperature and the average minimum temperature showed a decreasing tendency.Moreover,there was an obvious decreasing tendency for the average maximum temperature in the midmonth of August.The sunshine duration showed a decreasing tendency in the whole growth stage.The growing stage would shorten with the average temperature and the average minimum temperature increasing in the full-growing stage and vegetative growth.However,its decreasing would result in extending the growing stage of mid-season rice.The days of full-growing stage and vegetative growth of mid-season rice exhibited an extending tendency in the southeast,southwest,northeast and northwest of Hubei Province influenced by the change of comprehensive meteorological factors,but a shortening tendency in Jianghan Plain.The days of reproductive growth showed an extending tendency in the five regions mentioned above.
