| 摘 要： | 本研究采用具高产潜力的三个大豆新品种（生活费），研究了在不同密度，不同施肥水平下大豆干物质积累动态，作物生长率等，并在此基础上研究了干物质积累与经洲际是产量的相关关系。结果表明：品种间，不同施肥量间，不同种植密度间的干物质积累动态均存在较大差异；各阶段干物质积累量与经济产量呈正相关变化趋势，其中盛花期干物质积累与产量呈显著正相关。结荚鼓粒期干物质积累与产量呈极显著正相关。

| Abstract: | s The relationship between seed Yield and dry(air-dry) matter accumulation and their correlation coefficients were studied by using 3 soybean cultivars(lines) which have high yield potency,under 2 kinds of densities and 3 fertilizer levels. The result showed that dry matter accumulation were various in different growing period and the correlation coefficients of yield with the dry matter accumulation were tending to positive correlation although the difference were existed in different develoment period. |
