寒地大豆几种种植方式比较的研究

Comparition Between Several Soybean Planting Patterns in Cold Area

通过目前国内外大面积推广的大豆平作窄行密植种植方式以及由其与黑龙江省实际结合而产生的大垄窄行密植种植方式与现在生产上较普遍应用的垄作种植方式的对比试验，结果表明，在高寒地区，大豆缩小行距，扩大株距的栽培方式可以获得较大幅度的增产，平作窄行密植方式最高可增产２７．１４％ ，选用适宜的品种和密度。

Several soybean planting patterns including SSS (solid-seeded-semidwarf) system, solid-seeded in wide ridge and general size ridge planting were compared. The result indicated that the soybean yield could be increased by narrowing the ridge and increasing the planting density in high latitude district. The soybean yield increased by 27.14% in the solid-seeded narrow row planting pattern so the pattern could be applied in cold area.
