摘　　要：为了指导稻农进行水稻混合种植,以垦稻12与绥粳4号为供试材料,采用二因素随机区组设计方法对寒地水稻混合种植进行了研究。结果表明:垦稻12与绥粳4号混合种植时,不同处理对水稻影响较大的是结实率,氮肥量大小与种子混合比例直接影响分蘖力,抗倒伏能力,致使产量变化;对产量贡献率大小依次为氮肥量与种子混合比例互作>氮肥量>种子混合比例;氮肥量116.7kg·hm-2,垦稻12和绥粳4号混合比例6∶4互作时产量最高,为8 933.3kg·hm-2。In order to guide farmers to plant with mixed rice varieties,taking Kendao 12 and Suijing 4 as experimental materials, mixed planting of different rice varieties in cold region was researched by two factor randomized block method . The results showed that when Kendao 12 and Suijing 4 were mixed planted, the seed setting rate was the most affected index among different treatments, the nitrogen application and mixed proportion make influence on tillering ability and lodging tolerance directly,change the yield;yield contribution rate：interactions of nitrogen application and seed mixed proportion〉 nitrogen application〉 seed mixed proportion; the yield （8 933.3 kg·hm^-2 ） was the highest when the nitrogen application （ 116.7 kg · hm^-2 ） and （Kendao 12 ： Suijing 4 = 6 ： 4 ） interact each other.
