摘要
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 conducted in Hua Chuan county in 1995￣1996. We analysised the effect of variety, density and row spacing on flat plowing and condensed planting soybean. The result showed that the differences among varieties and row spacings were significant. The variety with the highest yield was Beifeng 11. The row spacing of the highest yield was 22.5cm. Three densities and 2 row spacings of the same variety (Beifeng 11) were compared. The highest yield was from the density of 44.4 plants/m 2 and 15cm row spacing. With the row spacing increased, the space distribution of pods, seeds and seed weight in plants changed: decreascd at top, increased at bottom and less change in the middle.
