According to phenological observation data of fourteen stations in Hunan,Hubei and Jiangxi provinces from 1994 to 2006,indices of suitable temperature at the booting stage and accumulated temperature(≥10 ℃)during the whole growth period in early or late rice in the south of China were analyzed by statistics and biological relationship between factors.Indices of the optimum daily mean temperature and the minimum temperature at the booting stage were as follows:Early convention rice variety was 25.7 ℃ and 22.3 ℃ respectively,hybrid variety was 26.5 ℃ and 23.3℃ respectively;while late convention rice variety was 25.6 ℃ and 22.3 ℃ respectively,hybrid variety was 25.8 ℃ and 22.6 ℃ respectively.Indexes of accumulated temperature during the whole growth period were as follows:The early-maturing variety,the middle-maturing variety and the late-maturing variety of early rice was 2 512.1 ℃,2 528.4 ℃ and 2 651.3 ℃ respectively,while the early-maturing variety,the middle-maturing variety and the late-maturing variety of late rice was 3 126.2 ℃,3 031.5 ℃ and 3 335.2 ℃ respectively.The above indexes all met the requirements of identification,which could provide reference for formulating the meteorological standard of rice in the south of China.
