摘要
本研究以 7年制粮草轮作形式 ,自 1 985～ 1 991年 ,在科尔沁沙地中南部风沙土地区 ,探讨了种草养地、养畜 ,提高农业、发展牧业的关系。结果表明 ,在一个轮作周期中 ,人工种草年hm2 鲜草 1 3350 1 5kg ,粮食平均每hm2 产 582 7 35kg ,可饲用牧草和秸秆量 2 51 3 5kg ,分别比对照增产 1 2 3 97%、1 0 9 5%和 1 0 3 76%。载畜量可提高一倍 ,同时 ,饲草和粮食生产成本下降 50 %。试验表明 ,种植豆科牧草是一项养地、兴农、促牧的生物养地措施 ,也是符合高产、高效、低成本现代农业的要求 ,是科尔沁沙地值得提倡和推广 。
s:The relationship among planting herbage for fertilizing Land raising livestockes and inhancing farm and animal productivity was traced in a 7-year herbage crop rotation. The trial lwuas conducted from 1985—1991 in the area of mid-south keerqin Sandy Land.Comparison between the control and the trial field showed that the yields of the green grass the grain and the available herhage and straw had a remarkabl incerease respectively The results indicated that planting Leguminous herhage uas not only a good biologicel means of fertilizing dand but also a good method which was worthy of advocating and extending in Keergin Sandy Land and had a great potentiality of development.It was also consistent with the modern agriculture which demand high yield ,high efficiency and low cost.
