摘　　要：本研究旨在探讨不同播期和密度对大豆品种齐黄34产量的影响,采用二因素随机区组设计,A因素播期因子6个水平,B因素密度因子7个水平。结果表明:齐黄34产量随着播期的延迟、密度的增加呈先增后降趋势,差异达到极显著水平;齐黄34最佳播种时期为6月17日左右,最适密度为19.5万株/hm^2,此条件下可获得最高产量3 615.14kg/hm^2。This experiment was designed to investigate the effects of different sowing date and planting density on yield of soybean variety Qihuang 34. The results showed that with the delay of sowing date or with the increase of density,the yield showed a trend of first increasing and then decreasing. Significant differences were observed among treatments. The best sowing time was June 17 and the best planting density was 195 thousand plants/hm^2.The yield of Qihuang 34 reached to 3 615.14kg/hm^2.
