摘　　要：合丰55是黑龙江省农业科学院佳木斯分院2008年育成的优良大豆品种,该品种具有超高产、高油、抗病、广适应性等突出优点。为了进一步探索该品种的高产优质栽培技术,采用二因素三重复完全随机区组试验,研究不同播种密度与施肥水平对其油分及产量影响。结果表明:播种密度和施肥水平对高油大豆品种产量影响显著,随密度的增加和常规施肥量提高,高油大豆产量呈先上升后下降的变化趋势;不同密度和施肥水平对高油大豆油分含量影响达极显著水平,随着密度的增加油分含量下降明显,随着施肥量的增加油分含量先上升后下降;密度和施肥量互作对产量及油分含量影响显著。Hefeng 55 is an elite soybean cultivar with high-yield,high-oil,disease-resistance and wide-adaptability,the planting area was 292800 hectares in 2010,and occupied the third position of planting area in Heilongjiang province.The influence of sowing density and fertilizer levels on yield and oil content of Hefeng 55 were studied using randomized complete block design.Soybean yield showed increase and then decrease trend with the increasing of sowing density and fertilizer levels,and the differences reached very significant level;the oil content showed increase and then decrease trend with the increase of fertilizer levels,while decreased with the increasing of sowing density.The interaction of sowing density and fertilizer level had significant effect on yield and oil content of soybean.
