| 摘 要： | 为探讨密度与施肥对大豆产量及品质的影响,2007～2008年于内蒙古民族大学试验农场,以吉育35为试验材料,采用裂区田间试验设计,以密度为主区,以氮肥施用水平为副区,对高油大豆产量及品质进行了研究.结果表明:密度、施氮通过对高油大豆叶面积指数与叶绿素含量动态变化来影响植株的干物质积累最终对产量和品质产生影响.密度与施氮...

| Abstract: | A split-plot design with the planting densities as main plot and N-fertilizer levels as sub-plot was adopted.The effects of planting densities and N-fertilizer levels on yield and quality of Jiyu35 were studied in the farm of Inner Mongolia University for the Nationalities in 2007～2008.The results showed that planting densities and N-fertilizer levels affected the plant dry matter accumulation by leaf area index dynamics and chlorophyll dynamics,which affected the yield and quality at last.The yield increased and then decreased with the increasing of planting densities and increased with the increasing of N-fertilizer levels.The fat content was sensitive to planting densities and decreased with the increasing of planting densities,while protein content showed negative trend.The fat and protein contents were not sensitive to N-fertilizer levels. |
