摘要
对北方农区苜蓿及玉米青贮 +小黑麦种植模式的经济效益调查分析表明 ,干物产量成本以玉米青贮最低 ,为 15 5 .5元 / t,小黑麦最高 ;从整年看 ,青贮玉米 +小黑麦干草或青贮的干物成本和苜蓿干草相近 ,2 34.5～ 2 80 .9元 / t;但从营养成分看 ,苜蓿粗蛋白成本仅 1.5 4元 / kg,显示出明显优势 ,加之营养转化的间接效益 ,苜蓿的经济效益是较好的。并指出 。
The costs of alfalfa and common rye + corn silage production we re analyzed. The results showed that the cost of corn hay was as lower as 155.5 RMB/t because of high yield. However, that of corn + common rye hay performed a similar trend as alfalfa hay which was as high as 234.5～280.9 RMB/t. From the c ost of alfalfa hay 1.54 RMB/kg, it was regarded as a predominant and well econom ic forage. To increase hay yield and lengthen the utilizing years were effective methods to reduce the cost of alfalfa production.
