辽宁省彰武北部地区实行草地农业的效益

EFFICIENCY OF GRASSLAND FARMING IN NORTHERN LIAONING PROVINCE

通过对辽西北地区３种不同生产类型——粮、草、肉牛型，粮猪型和单一粮食生产型的科技示范专业户生产状况及经济效益进行调查对比，证实了粮、草、肉牛生产类型的生产结构较为合理，有益于改善种植业结构，增加产出，提高劳动生产率，具有一定的集约化水平和规模效益。由此认为，粮、草、肉牛生产类型在彰武地区乃至辽西北地区具有广泛的发展前景和生产潜力。

hrough investigation of different production type——grain crop+forage crop+meat cattle, grain crop+pig, grain crop only, the productive conditions and efficiencies of different demonstration farms was compared. It was proved that, grain crop+forage crop+meat cattle type had reasonable structure, it favoured planting structure improvement, increased production output, increased labouring force and had certain extensive level and scale efficiency. Grain crop+forage crop+meat cattle production type could have widespread development perspective and productive potential in Zhangwu area as well as whole northern Liaoning province.
