摘　　要：以辽黑1号为材料,研究了不施底肥,而在开花期追施氮肥下,4种施氮水平对辽黑1号的产量以及氮、磷、钾积累分配规律的影响。结果表明:施氮不仅能增加干物质积累和产量,还有助于氮、磷、钾向籽粒中分配。在N1氮肥处理下的产量最高;N2氮肥处理时,黑豆植株积累的氮素最多。各施肥处理与对照相比,均有助于氮素向籽粒中分配,但以N1氮肥处理时向籽粒分配的最多。施氮处理对磷素吸收分配规律的影响与氮素相同。氮肥的施用有助于钾素向籽粒中分配,但各处理间差异不明显。建议生产上施纯氮45 kg.hm-2对产量有明显增加的作用。Black soybean has high medicinal purposes and health care value, it also has high agricultural increment potential, the distribution of black soybean in China is broad, it had been widely produced in northeast China, Shandong, Shaanxi, Henan and other provinces. To provide theory basis for high yield black soybean cultivation, black soybean cultivar Liaohei 1 was used as material, the effect of topdressing nitrogen in flowering period and no bottom fertilizer was studied, four nitrogen fertilizer treatment of 0 kg·ha^-1 （NO） ,45 kg·ha^-1 （ N1 ） ,90 kg·ha^-1 （N2） and 90 kg·ha^-1 in addition of 22.5 kg·ha^-1 by spraying on leaves surface（N3） were used. The effect of 4 kinds of nitrogen level on yield and the rifles of accumulation and distribution in nitrogen, phosphorus and potassium were discussed. The results indicated that nitrogen fertilizer not only enhanced the dry matter accumulation and yield but also facilitated the partition of nitrogen ,phosphorus and potassium to the seeds. The yield was highest under the treatment of N1 ,while the most nitrogen was accumulated under the treatment of N2. Compared with the treatment of NO, all the treatments were helpful to the partition of nitrogen to the seeds,while the partition was highest under the treatment of N1. The influence of different nitrogen fertilizer levels on absorbtion and distrubution of phosphorus was the same to the nitrogen. Nitrogen fertilizer was helpful to the partition of potassium to the seeds, and there were no significant difference in each treatment. In the production it was suggested that the yield of black soybean could be obviously increased under the nitrogen of 45 kg · ha^-1.
