【摘要】 以中黄30、铁丰31和铁豆37为材料,在不同施肥和不同种植密度(12.0、16.5、21.0万株·hm-2)处理下,比较了3个大豆品种的农艺性状、产量和品质表现。结果表明:不同密度下,大豆产量差异极显著,并且高密度条件下的产量最高;不同肥力条件下,大豆产量差异不显著。不同肥密处理对不同大豆蛋白质和脂肪含量影响不同,低密度中肥处理提高了中黄30和铁豆37蛋白质含量,降低了3个大豆品种脂肪含量。中密度中肥处理提高了中黄30和铁丰31蛋白质含量。施肥处理降低了中黄30脂肪含量,提高了铁丰31和铁豆37脂肪含量。高密度施肥处理提高了中黄30和铁豆37蛋白质含量。施肥处理增加了铁丰31脂肪含量。更多还原

【Abstract】 We compared the agronomic character,yield and quality for Zhonghuang 30,Tiefeng 31 and Tiedou 37 under different fertilizer levels and planting densities(12.0,16.5,21.0 × 104 plants·ha-1),Results showed(ⅰ) the seed yield varied with plant density significantly and got highest underplant density of 21.0 × 104 plants·ha-1,while was not significant under different fertilizer level;(ⅱ) Seed protein and oil varied with fertilizer levels and planting density,protein content of Zhonghuang 30 and Tiedou 37 was improved,while seed oil was decreased under middle fertilizer level and low plant density;(ⅲ) The protein content was improved for Zhonghuang 30 and Tiefeng 31 in middle fertilizer level and middle plant density.The seed oil concent was decreaesed for Zhonghuang 30 in the treatment of fertilizer and the seed oil concent was improved for Tiefeng 31 and Tiedou 37 in middle plant density;(ⅳ) The seed protein concent was improved for Zhonghuang 30 and Tiedou 37 in the treatment of fertilizer and high plant density.The seed oil content was improved for Tiefeng 31 in the treatment of fertilizer.更多还原
