Abstract: This study was aimed to explore the effects of different cutting times and varieties on the yield and nutrient value of three different varieties of Italian ryegrass (Lolium multiflorum). The results showed that, the variety had a great influence on the yield,‘Jumbo’ had the highest hay yield (35 698.27 kg·hm-2);the highest fresh-dry ratio and crude protein content which were 4.47 and 17.8% DM,respectively. The content of neutral detergent fiber was the lowest,which was 52.21% DM;with the increase of cutting stubble,the crude protein content showed a downward trend. The hay yield of ryegrass reached its peak in early August from the point of cutting time. Swords and Treasures can be selected for promotion and planting in the north region. In order to obtain higher yield,the field management of the first three crops of ryegrass should be paid attention to;with the high nutritional value,we choose the first crop of high-protein and low-fiber forage.

Key words: Italian ryegrass, Variety, Cutting times, Yield, Nutrient value

摘要: 为提高北方饲草品质,充分发挥多花黑麦草(Lolium multiflorum)饲用价值,以3个不同品种的多花黑麦草为试验材料,探究不同刈割茬次及品种对多花黑麦草产量及营养价值的影响。结果表明:品种对产量的影响较大,在3个供试品种中,‘剑宝’的干草产量最高,达到35 698.27 kg·hm-2,鲜干比值及粗蛋白质含量最高,分别为4.47,17.8% DM,中性洗涤纤维含量最低,为52.21% DM;随着刈割茬次的增加,粗蛋白质含量呈下降趋势;从刈割时间来看,多花黑麦草的干草产量在8月上旬达到峰值。因此,在北方地区的黑麦草生产中,可选用‘剑宝’品种进行推广种植,若以高产为收获目标,则应注重前3茬黑麦草的田间管理工作;若以高营养价值为收获目标,则可选择第1茬次的高蛋白低纤维饲草。
