摘　　要：为研究密度对糜子农艺性状及产量的影响,以雁糜11号为材料,选取6个不同的播种密度(52.5万、60.0万、67.5万、75.0万、82.5万、90.0万株/hm^2)进行研究。结果表明,随着种植密度的增加,株高、主茎粗、主茎节数及主穗长等逐渐减小,而主穗质量、主穗粒质量、总穗质量、总粒质量及产量则呈现先增加后减少的趋势;播种密度60.0万株/hm^2的产量最高,为3 566.85 kg/hm^2,此密度为雁糜11号的最适栽培密度。To study the effect of density on the agronomic traits and yield of Panicum miliaceum L., with Yanmi 11 as the material,six different seeding densities of 0.525, 0.600, 0.675, 0.750, 0.825, 0.9 million plants/hm^2 were used in this study. The results showed that with the increase of planting density, plant height, main stem diameter, number of main stem section and main spike length, etc decreased, and the main spike quality, main spike grain quality, total spike quality, total grain quality and yield first increased after decreased. When planting density was 0.600 million plants/hm^2, yield was the highest（3 566.85 kg/hm^2）, this density was the optimum cultivation density of Yanmi 11.
