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 excellent soybean variety bred in Jiamusi Branch of Heilongjiang Academy of Agricultural Sciences in 2008, which has the outstanding advantages of super high yield, high oil resistance, wide adaptability and so on. In order to further explore the high-yielding and high-quality cultivation techniques of this variety, we studied the effects of different sowing densities and fertilization levels on the oil content and yield by two-factor and three-repeat complete randomized block experiments. The results showed that sowing density and fertilization had significant effects on the yield of high oil soybean varieties. With the increase of density and conventional fertilization, the yield of high oil soybean increased at first and then decreased. The effects of different density and fertilization levels on high oil soybean oil With the increase of the density, the oil content decreased obviously. With the increase of the amount of fertilizer, the oil content first increased and then decreased. The interaction of density and fertilizer amount had a significant effect on the yield and oil content.
