内蒙古兴安盟地区34个紫花苜蓿品种营养价值比较研究

目的] 筛选内蒙古兴安盟地区营养价值较好的紫花苜蓿品种。方法] 以国外引进的34个紫花苜蓿品种为试验材料,在内蒙古兴安盟地区开展种植试验,测定各参试品种紫花苜蓿的粗蛋白、粗脂肪、粗灰分、中性洗涤纤维和酸性洗涤纤维含量,计算相对饲用价值,运用隶属函数法对营养价值进行综合评价。结果] 参试的34个紫花苜蓿品种中,粗蛋白、粗脂肪、粗灰分、中性洗涤纤维和酸性洗涤纤维含量最高的分别是“SK3010”“阿尔冈金”“康赛”和“挑战者”。相对饲用价值最高的品种是“巨能2”。隶属函数法综合评价较好的3个参试品种是“巨能2”“SK3010”“阿尔冈金”。结论] 参试的34个紫花苜蓿品种中“巨能2”“SK3010”“阿尔冈金”3个品种在内蒙古兴安盟干旱冷凉区具有较高的推广利用价值。

Comparative Study on Nutritional Value of 34 Alfalfa Varieties in Hinggan League,Inner Mongolia

Objective] To screen alfalfa varieties with higher nutritional value in Hinggan League, Inner Mongolia. Method] Using 34 foreign alfalfa varieties as experimental materials, planting studies were carried out at Hinggan League, Inner Mongolia. The contents of crude protein, crude fat, crude ash, neutral detergent fiber and acid detergent fiber of the 34 varieties were measured.The relative feeding value were calculated, and the nutritional value was comprehensively evaluated by membership function method.Result] Among the 34 alfalfa varieties tested, the highest contents of crude protein, crude fat, crude ash, neutral detergent fiber and acid detergent fiber were 'SK3010', 'Algonquin', 'Kangsai' and 'Challenger' respectively. 'Juneng 2' had the highest relative feeding value. The varieties with a superior overall evaluation using the membership function approach were 'Juneng 2', 'SK3010' and 'Algonquin'. Conclusion] Among the 34 alfalfa varieties evaluated, 'Juneng 2', 'SK3010' and 'Algonquin' had higher promotion and utilization value in the cold and dry area of Hinggan League, Inner Mongolia.
