| 摘 要： | 以国审早熟春大豆品种湘春豆26为供试材料,研究了播期和密度对南方早熟春大豆产量和品质的影响。结果表明,南方早熟春大豆产量随播期的延迟、密度的增加呈先增后降趋势;蛋白质含量、蛋脂总含量随密度的增加先增后减,随播期推迟而降低;脂肪含量随密度的增加而降低,随播期的推迟而降低。适期早播,合理密植有利于早熟春大豆高产,同时提高蛋白质含量和蛋脂总含量。

| Abstract: | In this study,effects of sowing date and planting density on yield and quality of a national authorized early maturing spring soybean variety,Xiangchundou 26,were studied.The results showed with the delay of sowing date or with the increase of density,the yield showed a trend of first increasing and then decreasing.The content of protein and the total content of protein and fat showed a trend of first increasing and then decreasing with the increase of density,and showed a trend of decreasing with the delay... |
