为了探讨多花黑麦草在新疆北疆的生产性能、干草的制作及其营养成分,本研究选择在呼图壁种植多花黑麦草,通过测定株高、茎叶比、鲜草产量和干草产量等指标分析其在北疆的生产性能。通过制作黑麦草干草和测定分析黑麦草的粗蛋白质、粗脂肪、粗纤维、钙、磷等营养指标,揭示黑麦草干草的营养价值。结果表明:多花黑麦草的株高为85.86 cm,鲜草产量重为32 250 kg/hm2,干草产量为4 356 kg/hm2,茎叶比为0.49%;水分、粗脂肪、粗蛋白质、无氮浸出物、粗纤维、钙、粗灰分、磷分别为7.64%、1.38%、12.73%、7.19%、28.92%、0.36%、42.44%、0.14%,说明多花黑麦草在新疆生长性能良好,营养丰富,黑麦草干草在新疆具有广泛的应用前景。

In order to explore the production performance of Lolium multiflorum Lamk in northern Xinjiang,the production of hay and its nutritional components, this study chose to plant Lolium multiflorum Lamk in Hutubi, and measured the plant height, stem-leaf ratio, fresh grass yield and hay yield. Analyze its production performance in northern Xinjiang with other indicators. Through the production of ryegrass hay and the determination and analysis of ryegrass' crude protein, crude fat, crude fiber, calcium, phosphorus and other nutritional indicators, the nutritional value of ryegrass hay is revealed. The results showed that the plant height ofLolium multiflorum Lamk was 85.86 cm, the yield of fresh grass was 32 250 kg/hm2, the yield of hay was 4 356 kg/hm2, and the stem-leaf ratio was 0.49%; moisture, crude fat, crude protein, and no Nitrogen extract, crude fiber, calcium, crude ash, and phosphorus are 7.64%, 1.38%, 12.73%, 7.19%, 28.92%, 0.36%,42.44%, 0.14%, respectively, indicating that ryegrass grows well in Xinjiang. Rich in nutrients, Lolium multiflorum Lamk hay has broad application prospects in Xinjiang.
