摘　　要：在全膜双垄沟播技术条件下进行青贮玉米不同密度比较试验,结果表明:全膜双垄沟播技术条件下青贮玉米最佳种植密度为8.25万株/hm^2,此密度条件下鲜草产量96 072.0 kg/hm^2,产值28 821.1元/hm^2,纯收入为16 335.0元/hm^2,投产比达到1∶2.3。Comparative tests of different planting density of silage corn under full plastic film cover on the double ridges were carried out in this paper. Results showed that the best planting density was 82 500 plants/hm^2, under which the output reached 96 072.0 kg/hm^2, income reached 28 821.1 yuan/hm^2, pure income reached 16 335.0 yuan/hm^2, input and output ratio reached 1 ： 2.3.
