摘　　要：以合丰50为材料,分7个播期、5个密度,研究不同播期及密度对其品质、产量及农艺性状的影响。结果表明:播期及密度对高油高产大豆品种合丰50的产量有较大的影响,随播期的延迟和密度的增加,该品种的产量呈先上升后下降的变化趋势,差异达到极显著水平;播期对油份含量的影响较大,而且规律性极强,即随播期的延迟各密度处理合丰50的油份含量下降。不同密度处理对油份含量的影响较小,而且规律性也不强。合丰50的最佳播种时期为5月9日左右,而最适密度为25万株.hm-2,此时可获得最高产量和较高的含油量。New soybean variety Hefeng 50 was used to study the response of oil content and yield to different sowing dates （25th April,2nd May ,9th May ,16th May,23th May,30th May,6＇h June）and densities（20,25,30,35 and 40 104plants · ha^-1 ）. Results showed that sowing dates and densities had great influence on yield of Hefeng 50,with the sowing date delayed and density increased, the yield of Hefeng 50 showed increase-and-then-decrease trend, and significant difference were observed among treatments;sowing dates ilad significant influence on oil content, with the sowing date delayed, the oil content dec, reased regularly;planting densities had no obvious influence on oil content. Results suggest that under the planting density of 25 ×10^4plants·ha^-1 and the sowing date of 9th May, soybean variety Hefeng 50 had highest yield with higher oil content.
