摘　　要：通过对不同结荚习性大豆品种各生育阶段的长短、生长发育的速度和植株上、中、下各部位的产量分布、子粒内含品质的测定,明确了不同结荚习性大豆品种各自的生育规律与特点。结果表明,不同结荚习性大豆品种子粒的大小和子粒蛋白质与脂肪总含量与子粒产量在各部位分布的规律基本一致。研究还进一步讨论了不同结荚习性大豆品种的形成机理、子实产量形成的重点时期与部位及其对环境条件的适应特点与分布规律,以及在优质高产栽培中应注重其不同的重点促进期。According to determination for growth characters of differ, ent podding propensity soybean varieties, such as length, growing velocity in different period, production status on different parts of plant and quality of bean, we found the growing rules and characters of different podding propensity soybean varieties, The result shows that different podding propensity soybean varieties have basic same rule on size of bean, contents of protein and fat of bean, and produetion status of different parts of plants. The further discussion shows that mechanism of different podding propensity soybean varieties, major period and part of yield -building of bean, suitability to condition of circumstance and distribution rule. And it also shows it is important to pay attention to the key period of growth in cultivation for high quality and yield.
