[目的]探讨坡地大豆的3种种植方式的增产效果,为坡地种植大豆高产提供理论依据.[方法]共设3个处理,采用随机区组设计,2次重复.[结果]行距40 cm、株距20 cm双株种植较传统的行距40 cm、株距10 cm单株种植增产显著,每667 m比传统单株种植的大豆增产77.6 kg.而株距20 cm双株种植与株距30 cm 3株种植、株距30 cm 3株种植与传统株距10 cm单株种植之间差异不显著.[讨论]综合考虑,在承德地区大豆最好采用行距40 cm、株距20 cm双株种植方式.%[ Objective ] The aim was to explore the increasing yield of slope land soybean by planting in three methods, which shall provide basis for planting slope-land soybean. [ Method] 3 treatments, random block design and two repeating were adopted. [ Result] The yield of the treatment of row spacing 40 cm, seed spacing 20 cm and double planting was increasing significantly than that of the treatment of traditional method which row spacing 40cm, seed spacing 10cm and single planting. Average yield per mu was increasing 77.6 kg than traditional method. There were no obvious different between treatment of seed spacing 20 cm double planting and treatment of seed spacing 30 cm three planting, treatment of seed spacing 30 cm three planting and traditional method of seed spacing 10 cm planting. [ Discussion] Considering from all aspects, the best planting method in Chengde area was 40 cm row spacing, 20 cm seed spacing and double planting.
