摘　　要：选用适于合肥地区种植的黑豆品种安选一号,进行了播期、种植密度和追施氮肥量的正交试验,并在成熟期测定了黑豆产量及产量构成因素和黑豆籽粒蛋白质、油分含量。结果表明:早播可以有效提高产量和蛋白质含量,适当稀植、加大追肥量能提高黑豆产量及其脂类含量。当6月10日播种、播种密度90000株/hm2、追肥量为150kg/hm2时,黑豆产量最高。The experiment was set out from June to November in 2006, and select black soybean - 1 which is suitable for Hefei area was selected for the experiment including sowing （broadcasting） time, cultivating density and nitrogen topdressing amounts （there levels） were used, The test adopted orthogonalization experiment design, Output and output composing factors, seed protein and oil contents were determined at the mature period. Results indicates that earlier sowing raised output and protein content. Appropriate sparse sowing, enlarged N topdressing amounts raised black soybean output and seed oil content. Out is maximal when sowing dated on June 10 and cultivating density at 90000 stands per hm^2 and topdressing amounts 150 kg· hm^-2.
