摘　　要：在青岛胶州,开展了黄淮海地区不同播期对青贮玉米产量及营养品质的影响研究。通过对不同播期下4个不同品种青贮玉米农艺性状(株高、穗位、茎粗、绿叶数)、产量(鲜草产量、干草产量)、营养品质(粗蛋白、中性洗涤纤维、酸性洗涤纤维、粗脂肪)指标的测定,确定适合黄淮海地区的青贮玉米品种及其适宜的种植时间。结果表明:春播条件下的四个品种的产量均高于夏播,农艺性状也优于夏播。在产量和营养品质上,无论春播还是夏播,奥玉青贮5102和青贮祥糯606均表现较好,综合评定最佳,WK702和金阳光315次之。综上所述,奥玉青贮5102和青贮祥糯606更适合在黄淮海地区进行春播种植。The yield and nutritional quality of different silage corn varieties were studied in Jiaozhou city of Qingdao,in Huang-Huai-Hai region.The agronomic characters including plant height,ear position,stem diameter,green leaf numberof 4 different silage maize varieties,yield including fresh grass yield and hay yield,and nutrition were studied as well.The quality index including crude protein,neutral detergent fiber,acid washing fiber and crude fat was tested which determined the planting time of silage corn and silage corn varieties suitablity for Huang-Huai-Hai area.The results showed that the yield of 4 varieties under the spring sowing condition was higher than the summer sowing,and the agronomic characters were better than the silage corn under the summer sowing condition also.Under the spring sowing condition and the summer sowing condition,the Aoyuqingzhu5102 and the Qingzhuxiangnuo606 performed better both in biological yield and nutritional quality,and the comprehensive evaluation was the best,WK702 and Jinyangguang 315 followed them.In one word,Aoyuqingzhu 5102 and Qingzhuxiangnuo 606 varieties are the best choice for Huang-Huai-Hai area.
