摘要
在川中丘陵地区遂宁市河沙镇和天保镇,对5个苇状羊茅(Festuca arundinace Schreb.)品种进行牧草生产性能的比较研究,旨在筛选出适宜在该区种植的品种。结果表明,‘科瑞’在两个试点的生长速度和干草总产量均最高,分别为0.564cm·d^(-1)和8 842kg·hm^(-2),显著高于其它品种(P<0.05),其次为‘金刚’和‘马丁’。粗蛋白和可溶性碳水化合物产量均以‘科瑞’最高,分别为1 345kg·hm^(-2)和887kg·hm^(-2),均显著高于其它品种(P<0.05),其次为‘美食家’和‘金刚’;中性洗涤纤维和酸性洗涤纤维产量均以‘美食家’和‘科瑞’最低,二者无显著性差异。综上所述,‘科瑞’、‘美食家’和‘金刚’的干草产量较高,营养品质较好,在川中丘陵区具有较好的推广价值。
In order to screen out suitable tall festuca varieties for planting in hilly areas of central Sichuan Province,the field experiments were conducted to compare the production performance of 5 tall festuca cultivars in Hesha Town and Tianbao Town of Suining City.The results showed that the growth rate and hay yield of‘Kerui＇were the highest（P〈0.05）in the two test sites,which were 0.564 cm·d^（-1） and 8842 kg·hm^（-2）,respectively,followed by ‘Martin＇and ‘Jingang＇.In addition,the production of crude protein and water soluble carbohydrates were the highest in ‘Kerui＇with 1 345 kg·hm^（-2） and 887 kg·hm^（-2）,respectively,followed by‘Meishijia＇and‘Jingang＇.Whereas,the production of neutral detergent fiber and acid detergent fiber of‘Meishijia＇and ‘Kerui＇were the lowest（P〈0.05）,and there were no significant difference between these two cultivars.In summary,‘Kerui＇,‘Meishijia＇and ‘Jingang＇had the higher hay yield and nutritional quality,which could be popularized and have better application value in this area.
