摘要
根据谷物种子发芽率损失速率的正态分布理论，建立了种子热风干燥发芽率预测的数学模型，谷物种类包括大麦、小麦、玉米、高粱和大豆。以玉米为例，重点讨论了热风温度与种子初始水分对干燥过程中种子发芽率损失速率的影响。模拟结果表明，随着热风温度的升高和种子初始水分的增大，种子发芽率损失速率将增大。
Based on the normally distributed death-rate theory, a mathematical model for the pre-diction of seed viability during hot air drying was developed.Five kinds of grain seed wereincluded in the model:barley,wheat,corn,sorghum and soybean.The effects of the air tem-perature and the seed initial moisture content on the seed viability were analyzed with corn asthe example.The simulation results indicated that the seed viability loss rate was positivelycorrelated with hot air temperature and seed initial moisture content.
