目前,全球平均气温比20世纪升高了0.6±0.2℃左右,我国平均气温升高了0.5~0.8℃,气候变化对水稻的生长具有重要影响。江西位于长江中下游,是我国重要的水稻产区。文章结合诸位学者的研究成果,探讨气候变化对江西地区水稻生产的影响及适应性,证实早稻提前播种最高可增产16.6%,中稻延后播种最高可增产17.3%,适当增加遗传参数G4(耐热系数)最高可增产20.0%,引进热带品种最高可增产67.0%。
At present, the global average temperature is about 0.6 ± 0.2 ℃ higher than that of the 20th century, and the average temperature in China is raised by 0.5 ~ 0.8 ℃. Climate change has an important impact on the growth of rice. Jiangxi is located in the middle and lower reaches of the Yangtze River, is China’s important rice producing areas. Combining with the research achievements of scholars, this paper discussed the effect and adaptability of climate change on rice production in Jiangxi Province. It proved that the highest yield of early rice could increase by 16.6%, the delayed sowing of middle rice could increase the yield by 17.3% and the genetic parameter G4 Coefficient) up to 20.0% increase, the introduction of tropical varieties can increase 67.0%.
