人工草地育肥羔羊的草业子系统力能学分析

Analysis on Agricultural Energetics of Fattening lamb Pratacultural Subsystem In Artificial Grassland

本文运用方兴末艾的农业力能学原理,对以季节畜牧业、轮牧、补饲等集约经营为特点的普通红豆草(Onobrychis Viciaeffolia Scop)人工草地育肥羔羊草业次级生产子系统首次进行了详尽的力能学分析。并以试验结果,充分说明了人工草地育肥羔羊的草业子系统具有较高的净产出能与投入能产投比,其中较定牧处理集约化的轮牧处理其产投比是定牧的1.24倍。

In this paper, the secondary production subsystem of grassland farming is first analysed in view of agric, energetics, which is intensive farming with animal husbandry, rotationl grazing and supplement. Meanwhile, the results determining on the basis of experment, indicates that the ratio of net energy output to input for supplements in the lambs fattening subsystem of artificial grassland. And also, the ratio of the rotational grazing system which is more intensive was is twenty-four persent higher than the continuous grazing system.
