摘要
依据系统工程理论,提出建设人工草地建议,满足家畜对能量和蛋白质的需要。经过8年努力,累计种植人工牧草18939.1hm^2,产青干草20.5t,可养34万只标准羊,纯效益3698万元,并取得了明显生态效益和社会效益。人工草地具有提高草地经济效益,增加载畜量,增加农业生产后劲,促林,促果,保水保土,改变生态环境的作用。
According to the theory of ecosystem engineering,that can be established artificial grassland,meet the need of animal for energy and protein.The area of artificial pasture has increased 18939.1hm^2,produced 20.5t green dry grass and feeded 340000 sheep,received 36980000yuan pure benefits and obvious effect of ecology and society in 8 years.Artificial pasture can increase the economical benefits of grassland,stock capacity,and agricultural production,and can promote forest and orchard,retain water and soil,change the ecological environment.
