【摘要】 为了研究刈割时期对紫花苜蓿(新牧1号、新牧2号、当地苜蓿、高辉苜蓿)和红豆草产量及营养价值的影响,试验测定了牧草产量及营养价值(含水量、粗蛋白质、粗脂肪、粗纤维、粗灰分、无氮浸出物、中性和酸性洗纤维等指标)的变化。结果表明:不同刈割茬次牧草营养品质的高低顺序为第一茬>第二茬>第三茬;不同品种牧草的营养品质高低顺序为新牧2号>新牧1号>高辉苜蓿>红豆草>当地苜蓿。说明牧草的最适刈割时期为第一茬,适宜的种植品种为新牧2号。更多还原

【Abstract】 To study the effect of mowing period on the yields and nutritional values of sainfoin and alfalfa varieties including Xinmu No.1,Xinmu No.2,local alfalfa,and Gaohui alfalfa,the changes in the yields and nutritional values of forage grasses,including water content,crude protein,crude fat,crude fiber,crude ash,nitrogen-free extract,neutral detergent fiber,acid detergent fiber and other indexes.The results showed that the nutritional quality of forage grasses with different mowing stubbles in a descending order were the first stubble,second stubble and third stubble; the nutritional quality of different varieties of forage grasses in a descending order were Xinmu No.1,Xinmu No.2,Gaohui alfalfa,sainfoin,and local alfalfa.The results indicate that optimum mowing time was the first stubble,and the suitable cultivar was Xinmu No.2.更多还原
