摘要
研究了不同施氮量(30、60和90 kg hm -1)对大豆重要产量指标(可育节数、单株荚果数和千粒重)的影响。试验于2009年在两个不同的地点(Zemun Polje玉米研究所和Kloka-lower Jasenica村)进行。试验采用田间小区试验，分4个重复。结果表明，在两种土壤类型中，施氮量为60 kg hm -1时，单株荚果数和千粒重平均增加5.2%和3.8%;施氮量为30 kg hm -1时，可育节数平均增加3.8%。与对照相比，施用90 kg hm -1 N使单株荚果数降低。
The influence of nitrogen fertilization on soybean important agronomic characteristics
The influence of different amounts of nitrogen (30, 60 and 90 kg ha-1) on important soybean yield components (number of fertile nodes, number of pods per plant and weight of 1.000 grains), was examined in this paper. Experiment was carried out at two different localities (Maize Research Institute Zemun Polje and the village Kloka-lower Jasenica) in 2009. Experiments were carried out through field plot trials, using split-plot in 4 replications. The results show that, on average, for both soil types, number of pods per plant and weight of 1000 grains increased using nitrogen dose of 60 kg ha-1 for 5.2 and 3.8% and the number of fertile nodes to the variant of fertilization with 30 kg ha-1 of nitrogen for 3.8%. The amount of 90 kg ha-1 N gave lower values of the number of pods per plant compared to the control.
