摘　　要：以青贮玉米龙辐单208为材料,研究了寒地不同收割期对青贮玉米营养价值的影响。试验结果表明,随收获期推后,青贮玉米全株粗蛋白、粗纤维含量呈递减趋势,粗脂肪变化规律不明显。北方寒地青贮玉米适宜收获期为授粉后40～50d。Based on the research of silage maize Longfudan208, this article studied the influence of different harvest dates on the nutrition value of silage maize in cold areas. Results of the research showed that as harvest date delayed crude albumen, crude fiber decline in silage maize, and crude ash increase. Changes of crude fat were not clear. From analysis of dry matter accumulation, the best harvest date northern cold area is 40 - 50 days after pollination.
