摘　　要：为小黑麦(triticale)东农96026在黑龙江省哈尔滨地区种植获得高的产量及较优的饲用品质,从栽培措施的密度及氮肥施用入手,采用裂区设计,4个密度水平(基本苗750万株/hm2,600万株/hm2,450万株/hm2,300万株/hm2),3个施氮水平(纯氮75kg/hm2、150kg/hm2、225kg/hm2),研究了不同密度和氮肥处理对小黑麦东农96026生长发育、产量及饲用品质的影响。结果表明,降低密度和增加氮素营养水平利于提高东农96026的生物产量,并具有较好的饲用品质。在种植密度为450万株/hm2、施氮水平为150kg/hm2时产量结构比较协调,品质最优。In order to obtain higher yield and better quality for feed of ＂Dongnong96026＂ in Harbin of Heilongjiang Province, we started the study based on the density and nitrogen fertilizer and using Split-plot design. Through four plant densities treatments （7.5 million basic seedling per hectare, 6 million basic seedling per hectare, 4.5 million basic seedling per hectare, 3 million basic seedling per hectare） and three N fertilizer application levels （75 kg/hm^2, 150 kg/hm^2, 225 kg/hm^2）, we studied the effect of density and N level on yield and feeding quality of triticale. The result indicated that lower density and higher N level were beneficial to biological yield and feeding quality. The best quality was found in this treatment of 4.5 million basic seedling per hectare and 150 kg/hm^2.
