Abstract: The paper aims to reveal the characteristics of double cropping rice’ s growth period in Hubei Province, quantitatively assess the effects of meteorological factors on rice yield. The author took the yield data and meteorological factors of double cropping rice of 4 representative stations in Hubei Province, analyzed the relationship between meteorological factors and double cropping rice’ s yield during 1961 to 2013 by using the dynamic statistical climate assessment model. The results showed that, early rice planting date was April 2, mature date was July 18, and the growth period lasted for 108 days, while later rice planting date was June 20, mature date was October 22, and the growth period lasted for 125 days. The length of the growth period of double cropping rice was different in 4 representative stations. The growth period of early rice appeared an increasing trend in Jiangxia and Jianli station, while Jiangxin and Xiaogan showed a shortening trend. Dynamic statistical climate assessment model showed that the air temperature had the most influence on the growth period of double cropping rice subjecting to geographical and hydrological conditions. Increasing air temperature and sunlight in critical growth stage of double cropping rice was favorable to yield formation, while more precipitation decreased double cropping rice yield. Under the background of climate warming, higher air temperature and less precipitation increased double cropping rice yield.
