摘要
研究了不同播期、密度和氮肥追施量对赣豆6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6号产量影响极显著,在施入等量的钙镁磷肥(375kg/hm2)和钾肥(100kg/hm2)前提下,赣豆6号在7月20日播种,密度为22.5万株/hm2,追施氮肥量为250kg/hm2的情况下产量最高,经济效益最好。
Effects of sowing date, planting density and N fertilization rate on the yield of soybean Gandou 6 and agronomic traits were investigated. Results showed that planting density, sowing date and interactions between nitrogen application rate and planting density had significant effects 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 July 20th with the planting density of 2.25 × 1^05 plants ha-1 and nitrogen side dressing of 250 kg/hm^2
