摘　　要：为寻找新的种植模式来提高青贮玉米(Zea mays)和饲用谷子(Setaria italica)的产量和土地利用率,以青贮玉米‘郑单958’和谷子‘饲用1号’‘饲用5号’为材料,采用随机区组试验,设置4种种植模式,青贮玉米单作(M)、饲用谷子单作(S)、青贮玉米与饲用谷子2?4混合种植(MS24)、青贮玉米与饲用谷子4?4混合种植(MS44)。测定作物各生育时期株高、茎粗、光合性能及产量等指标。结果表明,青贮玉米与饲用谷子间作模式下较单作显著提高了青贮玉米的株高、叶面积指数、叶绿素含量,MS24可获得最高青体产量和生物产量,分别为142.05和42.72 t·hm^(-2)。‘饲用1号’在种植模式MS24下青体产量最高,达到142.05 t·hm^(-2),‘饲用5号’间作MS24和MS44模式下比单作产量提高36.59%和34.57%。结果表明玉米谷子间作可以提高各自的产量,种植方式以玉米?谷子2?4种植可以获得较好的效果。To find a new planting mode to improve the yield and land use efficiency of silage maize and forage millet,this experiment took silage maize‘Zhengdan 958’,‘forage millet 1’,and‘forage millet 5’as materials,set four planting modes in random block experiment,and measured plant height,stem diameter,photosynthetic performance,and yield of crops at each growth stage.The results demonstrated that the plant height,leaf area index(LAI),and chlorophyll content of silage maize were significantly increased under the intercropping mode of silage maize with forage millet compared with the monocropping mode.The maximum cytology yield and biological yield were 142.05 t·ha^(−1) and 42.72 t·ha^(−1),respectively,when the intercropping ratio of silage maize with‘forage millet 1’was 2꞉4.The highest cytology yield was 142.05 t·ha^(−1) under the planting mode MS24,and the yield was 36.59%and 34.57%higher than that under the intercropping mode MS24 and MS44.The results demonstrated that corn-millet intercropping could improve their respective yields,and corn꞉millet 2꞉4 intercropping ratio could get better results.
