　　为了满足黑龙江红兴隆地区畜牧业发展对青贮玉米栽培技术的需求，以3个青贮玉米品种为试验材料，研究了4种种植密度对青贮玉米主要农艺性状及产量的影响。结果表明：不同密度间单株产量差异极显著；随着密度的增加中原单32和阳光1号的单株绿叶比率下降，而龙辐单208变化不大；青贮玉米的单株鲜重随着密度的增加而减少；阳光1号的适宜种植密度是6．5万～7．0万株?hm‐2，中原单32和龙辐单208的适宜种植密度是6．0万～6．5万株?hm‐2。

In order to meet demand for silage maize cultivation technology on animal husbandry development in Heilongjiang Hongxinglong area ,three silage maize varieties were tested in four planting density to study the variation on the main agronomic characters and yield .The results showed that there was significant difference on yield per plant among different density .The green leaf ratio of Zhongyuandan 32 and Yangguang 1 de-creased ,while that of Longfudan208 changed little with the increase of density .The plant fresh weight of test varieties decreased with the increase of planting density .The appropriate planting density of Yangguang1 was from 6 .5 thousand to 7 .0 thousand plants per hectare ,and that of Zhongyuandan 32 and Longfudan 208 was from 6 .0 thousand to 6 .5 thousand per hectare .
