摘　　要：试验以中熟的中原单32和晚熟的东青1号两个青贮玉米品种为材料,进行同行混播、间行混播,研究不同混播方式与青贮玉米各生育时期、产量和饲用品质的关系。结果表明,不同混播方式对青贮玉米品种生育时期影响不显著;实行2:2间行混播,并在中原单32达到乳熟末期时进行混合收获,可获得较高干物质产量和较好的饲用品质。This paper took intercropping and mixed planting silage corn varieties Zhongyuandan32 and Dongqingl as the test materials, and studied the relationship between different mixed planting modes and the production period, yied and feeding value of silage corn varietise. Therefore, the results showed that intercropped and mixed planting had no significant effects on phenophase, mixed harvest of intercropping 2：2 had higher dry matter yield and better feed value in milk stage telophase of Zhongyuandan32.
