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８７％～１７８％，最高增产２２５％。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。
With three different types of plant height, take the regional contrast method to study the cultivation of soybean and the appropriate density. The results showed that narrow-row cultivation increased yield significantly compared with conventional ridge cultivation, with an average yield of 8.7-7.8% and a maximum yield of 22.5%. The output of narrow row of flat row was slightly higher than that of big row and narrow row of narrow row, the difference was insignificant; the research on high yield and high efficiency supporting technology of soybean should adopt the method of narrow row and wide ridge planting; under the premise of lodging resistance, Variety should not be less than 50cm. The planting density of high-stalk varieties is 220,000-260,000 plants / hm2, medium-stalk varieties 260,000-300,000 plants / hm2, and dwarf varieties 300,000-350,000 plants / hm2.
