Impacts of sunlight and temperature on yield of rebirth-paddy

In order to discuss the effects of climate change on the growth of rebirth-paddy,the paper analyzed the ecological conditions of rebirth-paddy,the changing characteristics of sunlight and temperature and the climate-produce-potential of sunlight and temperature in the town of Zhuxi.The results show that sunlight and temperature are the main factors limiting the yield of rebirth-paddy.The average temperature and minimum temperature are most closely related to the yield.And sunshine and sky coverage are other two important factors relating to the yield of rebirth-paddy.The resource of light and heat is abundant in the research region,and the change of climate-produce-potential of sunlight and temperature is large,but there still exists a large gapbetween actual yield and climate-produce-potential of sunlight and temperature.The yield can be increased through breed-improving and agriculture measures.
