通过研究青贮玉米的密度与产量及产量构成因素的关系,结果表明:密度对青贮玉米的单株鲜重、粒重、穗重、分蘖力及绿叶数影响最大,密度是影响产量的关键因素,南北疆及其类似地区的青贮玉米高产密度不宜超过82500株/hm2,最佳经济生产密度为67500～82500株/hm2。
The results showed that density had the greatest effect on fresh weight per plant, grain weight, panicle weight, tillering ability and leaf number of silage maize. Density was the key factor affecting the yield. South and North Xinjiang and similar areas of silage corn should not exceed the high yield density of more than 82,500 plants / hm2, the best economic production density of 67500 ~ 82500 plants / hm2.
