In this paper, the path analysis method was used to analyze the effects of several major meteorological conditions on the yield of ratoon rice and the relationship between meteorological conditions and yield components. According to the autumn climate regulation in the southeastern part of Sichuan, the critical flowering and flowering stage of high and stable yield and high yield of ratooning rice was proposed and the frequency of safety assurance and high yield of stable and high yield were evaluated.
