试验于１９９５～１９９６年在桦川县进行，通过品种、密度、行距对大豆平作窄行密植栽培的效应进行分析，结果表明：品种间、行距间差异达显著水平，各品种以北丰１１号产量最高；各行距以２２．５ｃｍ行距的产量最高。同一品种（北丰１１号）三个密度二个行距比较，以４４．４株／ｍ２，行距１５ｃｍ的产量最高。随着行距的增加，单株荚数、单株粒数、粒重在各层分布，上层的荚数、粒数、粒重比例下降，下层比例增加，中层的变化不大。
The experiment was carried out in Huachuan County from 1995 to 1996. The effect of narrow row and close planting of Soybean flattened by variety, density and row spacing was analyzed. The results showed that there was a significant difference between varieties and row spacing. The highest yield; row spacing to 22.5cm row spacing of the highest yield. The same variety (Beifeng 11) three density row spacing compared to 44.4 / m2, spacing 15cm the highest yield. With the increase of row spacing, the number of pod per plant, the number of grain per plant and the weight of grain per plant were distributed in all layers. The number of pods, grain number and grain weight of the upper layer decreased, the proportion of lower layer increased but the change of middle layer was not significant.
