【摘要】 赣豆5号是国审优质大豆新品种,为探索该品种的最优高产栽培措施,为该品种的大面积推广应用提供科学依据,研究了不同播期、密度和氮肥追施量对赣豆5号产量及农艺性状的影响。结果表明,密度、播期、密度和氮肥互作效应对赣豆5号产量影响极显著,在施入等量的钙镁磷肥(375kghm-2)和钾肥(150kghm-2)前提下,赣豆5号在6月29日播种,密度取12万株hm-2,氮肥追施量为300kghm-2,产量最高,经济效益最好。更多还原

【Abstract】 Gandou 5 is a newly bred soybean cultivar with characters of high-yield and good-quality.To seek for the suitable cultivation techniques and promote the application of Gandou 5,effect of planting date,planting density and nitrogen application rate on yield and agronomic characters were investigated.Results showed that planting density,planting date,and the interaction between planting density and nitrogen application rate had significant effect on soybean yield.Under the normal calcium,phosphorus and potassium application,the greatest yield as well as best economic benefit was obtained when the planting date was June 29 with the planting density of 1.2×105 plants ha-1 and nitrogen side dressing of 300 kg ha-1.更多还原
