摘　　要：用３个株高类型不同的品种，采取大区对比法，研究大豆的种植方式和适宜密度。结果表明，窄行栽培比常规垄作显著增产，平均增产８７％～１７８％，最高增产２２５％。平作窄行产量略高于大垄窄行，差异不明显；研究大豆高产高效配套技术宜选用大垄窄行种植方式；在抗倒耐密的前提下，选择植株相对较高的品种，矮秆品种不宜低于５０ｃｍ。密植幅度高秆品种为２２万～２６万株／ｈｍ２，中秆品种２６万～３０万株／ｈｍ２，矮秆品种３０万～３５万株／ｈｍ２。The modes of plantation and density in soybean were studied using three types cultivars in plant height by comparing of large plots The results indicated as follow:The yields of soybean were increased 87%178%in average level,the highest was 225%using cultivation of narrow rideges than normal ridges the yields of soybean were not increased obviously using cultivation of narrow ridges on level than narrow on large ridge,but it was more convenient using narrow on large ridge than narrow on levelThe narrow on large ridge was suitable mode for effectual yield and higher output in soybean The cultivars of higher plants,which were lodging resistant and baring of higher density,should be selected,at least higher than 50 cmThe optimum density were 220 000260 000 plants perhectare for cultivar of higher plant,260 000300 000 plants per hectare for cultivar of middle plant and 300 000350 000 plants per hectare for short one.
