摘　　要：以黑龙江省目前推广的青贮玉米品种龙辐208、中原单32及高油115为材料,进行了品种单播、混播及其与秣食豆混播试验,研究混播方式对生物产量、饲用品质的影响。结果表明,混播可提高单株干物质含量,促进干物质积累;混播,尤其是不同品种玉米与秣食豆混播的生物产量和群体粗蛋白产量较相应品种玉米单播显著提高,经济效益显著增加。The paper investigated effects of mixed-planting mode on changes of biomass and forage quality with three treatments with three silage corn varieties which are recommended varieties in Heilongjiang Province-Longfu 208,Zhongdanyuan 32 and Gaoyou 115.The three treatments included single planting,mixed planting of different varieties and mixed planting with fodder soybean.The results showed that the treatment of mixed planting could increase dry matter content and promoted dry matter accumulation.At the same time,the treatment of mixed planting,especially with fodder soybean,had higher biomass than the treatment of single planting.Silage corns which were mixed-planted with fodder soybean dramatically improved crude protein contents,resulting in outstanding economic benefit.
