以稻谷干燥时的活力退化动力学方程为基础 ,结合稻谷玻璃化转变理论建立了稻谷种子安全干燥温度模型。并通过稻谷种子的发芽率试验确定了种子安全干燥温度模型方程的系数。数学模拟结果表明 ,稻谷干燥过程中随着水分的降低 ,种子安全干燥温度曲线存在一个最低点 ;依据稻谷初始含水率由高到低 ,其最低安全干燥温度由低到高 ,而且种子通过最低安全干燥温度曲线最低点以后所能承受的温度则有所提高 ;当稻谷初始含水率低于 13 % ( w.b.)时 ,种子安全干燥温度曲线后半段近似为一直线 ,不再有拐点 (最低点 )。论文最后提出了稻谷种子安全干燥温度和操作工艺 ,以及选择种子安全干燥温度时应注意的问题。 Based on the dynamic degeneration kinetics equation of rice dryness, a model of rice seed safty drying temperature was established based on the theory of rice glass transition. Through the germination rate test of paddy seed, the coefficient of the model equation of seed safety drying temperature was determined. Mathematical simulation results show that the drying temperature curve of rice has a lowest point with the decrease of moisture during the drying process. According to the initial moisture content of rice from low to high, the minimum safe drying temperature is from low to high, and the seed passes the minimum safety When the initial moisture content of paddy is less than 13% (wb), the latter half of the curve of seed safety drying temperature is approximately a straight line with no inflection point (the lowest point ). Finally, the thesis puts forward the safe drying temperature and operating process of rice seeds, and the problems that should be paid attention to when choosing the safe drying temperature of seeds.
