摘　　要：在一般肥力土壤和栽培条件下,研究了密度对天农青饲1号高粱-苏丹草杂交种主要经济性状的影响。结果表明,主茎茎粗、单株分蘖数、穗粒重随密度增大呈下降趋势,鲜干物质产量以13.5万株/hm2密度处理为最高,各密度处理子粒产量差异未达到显著水平。The effects of density on economic characters of Tiannong grassfodder number 1 from hybridization of sorghum-sudan grass were studied under normal fertile soil and cultivated condition. The result showed that the width of stem, tillering number, grain weight of spike were decreased with the increase of the density, the fresh and dry matter yield reached the highest at a density of 135000 plants per ha, the grain yield was not significant difference under different density.
