Abstract: Aiming at the problems of poor aeration and low germination rate of rice buds during the process of rice seed soaking and accelerating germination, the research and design of a small-scale automatic oxygen-enriching rice seed soaking and accelerating germination rate is low. The box can not only make up for the disadvantages of the traditional rice seed soaking and accelerating germination method, but also meet the demand for automation and miniaturized controllable equipment. Carry out rice seed soaking and accelerating germination experiment, taking temperature, aeration time, and aeration frequency as influencing factors, and germination rate as evaluation index. Orthogonal experiment was carried out, and the results were optimized by response surface analysis. The test results show that the best technical parameters for rice seed soaking and accelerating germination are: temperature 34.8℃, aeration time 34.8 min, and aeration frequency 10.2 min. At this time, the germination rate of rice is 97.89%.
