This paper discusses the influence of Champa rice on the rice cultivation in China. The following are the main points: (1) There was no real early ripening rice, but late rice in the Lower Changjiang (Yangtze) Valley before the introduction of Champa rice; (2) With the characteristics of drought resistance and early ripening, Champa rice is suited to the conditions, such as the drought in summer and fall and the poorly watered field increased in the Song Dynasty, in the Lower Changjiang Valley; (3) Champa rice changed the native single cropping of the late rice to early one in the Song Dynasty, which laid a foundation for the development of double cropping of rice in the Ming and Qing Dynasties; (4) As a contract, Taihu Lake area where water resource is sufficient, didn't need much Champa rice, so the old single late rice there remained until the modern times when the late rice changed to early one and single rice to double one.
