摘　　要：试验旨在探究不同种植密度对玉米与大刍草远缘杂交后代F8代中MT-8的产量和品质的影响。以MT-8为试验材料,设52500、60000、67500、75000、82500、90000株/hm^(2)共6个种植密度。结果显示,随着种植密度增加,MT-8的鲜重和干重均提高,种植密度为75000株/hm^(2)时达到最大值。种植密度为75000株/hm^(2)时,MT-8的营养物质产量较高,具有较高的饲喂价值,营养类型为NC型。研究表明,MT-8适宜的种植密度为75000株/hm^(2)。The experiment was to investigate the effect of different planting densities on the yield and quality of MT-8 in F8 generation of distant hybrid of maize and teosinte.MT-8 was used as the research material,and six planting densities of 52500,60000,67500,75000,82500,and 90000 plants/hm²were set up.The results showed that the both fresh weight and dry weight of MT-8 increased with the increase of planting density,and reached the maximum value when planting density was 75000 plants/hm².At a planting density of 75000 plants/hm^(2),MT-8 had higher nutrient yield and higher feeding value,and the nutrient type was NC.The study indicates that the suitable planting density of MT-8 is 75000 plants/hm^(2).
