摘　　要：研究干燥方法对大豆种子含水量下降速率及在不同含水量条件下对种子活力的影响。采用CaCl2、硅胶及真空干燥法获得不同含水量的种子,经回湿后进行发芽试验。结果表明,真空干燥、CaCl2干燥及硅胶干燥3种干燥方法,种子含水量最低分别降至4.44%,5.17%,5.66%,分别较对照降低了31.90%,20.71%,13.19%,发芽率分别为93.33%,77.33%,98.67%,分别较对照增加了21.65%,0.80%,28.61%,种子活力分别为16.05,13.92,16.77,分别较对照增加了20.2%,4.3%,25.6%。The main purpose of the study was to reveal the influence of drying method on the declining rate of water content in soybean seeds and seed vigor in various conditions of water content, so as to pro- vide reference for soybean seed storage. The three kinds of water content soybean seeds were obtained by drying method of calcium chloride, silica and vacuum, and the germination test are determined after humidified. The experiments results showed that the lowest water content in the seed were 4.44%,5.17%, 5.66% respectively, which were lower than that of the control by 31.90 %, 20.71%, 13.19 % respectively. The germination percentage were 93.33%,77.33%,98.67%,which were increased by 21.65%,0.80%, 28.61%compared with the control. The seed vigor was 16. 05, 13. 92, 16. 77, which were increased by 20.2%,4.3%,25.6% compared with that of the control.
