摘　　要：通过田间试验,研究了收获期对湖南省主栽的4个春大豆品种产量、品质及抗劣变性的影响。结果表明:在完熟期收获的大豆百粒重和单株粒重均最高;过早收获时种子蛋白质含量、蛋脂总含量低,过迟收获时则脂肪含量低;在成熟期至完熟期收获能获得具有较高发芽势和发芽率的种子;收获期适当提前有利于增强大豆种子的抗劣变性。In this study, the influences of harvest date on the yield, quality and resistance to seed deterioration were studied u- sing four cultivated spring soybean varieties of Hunan province. Results showed we could get the highest 100 - grain seed weight and seed weight per plant at full - ripe stage. If the soybean was harvested too early, the protein content and protein - fat total content in the seed were low. If the soybean was harvested too late, the fat content in the seed was low. Higher germination potential and ger- mination rate of seeds could be harvested at ripening to full - ripe stage. It was also showed that the resistance to seed deterioration of spring soybean was high when the soybean was harvested more early in its harvest period.
