根椐种子发芽率的数学模型,研究热风温度和种子初始水分对种子发芽率的影响。结果表明,随着热风温度升高,种子发芽率损失速率将增大,热风温度在45℃以下,为玉米种子干燥过程中的安全热风温度;随着种子初始水分的增大,种子发芽率损失速率将增大,种子的初始水分越大,选择的热风温度越低。经发芽率实验证明,玉米种子经丸粒化后,发芽率没有变化。在低水分情况下,丸粒化种子比未丸粒化种子发芽率稍高,丸粒化种子含水量在丸粒化前、丸粒化后及贮存一定时间无太大变化,丸粒化种子的加工工艺和干燥工艺合理。
The root germination rate of seed germination mathematical model to study the hot air temperature and initial seed moisture on the seed germination rate. The results showed that as the temperature of hot air increased, the rate of seed germination loss would increase, and the hot air temperature below 45 ℃ was the safe hot air temperature during the drying process. With the increase of seed initial moisture, the seed germination loss The rate will increase, the greater the initial moisture of the seed, the lower the temperature of the hot air selected. The germination rate experiments show that corn seeds after pelleting, the germination rate did not change. In the case of low moisture, pelleted seed germination rate is slightly higher than the pellet seed, pelleted seed moisture content before pelleting, after pelleting and storage time does not change much, pelleted seeds The processing technology and drying process is reasonable.
