【摘要】：山西省右玉县实施封山禁牧政策后,牲畜饲养方式由自由放牧转变为舍饲,合理调整种植业生产结构,对实现农牧结合,增加农民收入具有较强的现实意义。笔者在对山西省右玉县2014年牲畜饲草量供求平衡分析的基础上,兼顾耕地面积、粮油安全、饲草量和营养需求等约束条件下,以农民收入最大化为目标,对封山禁牧后右玉县的种植业结构进行优化分析。结果显示:秸秆可作饲草的农作物种植比例已经严重挤压豆类作物和其他经济作物的种植空间,虽然能够最大限度减轻牲畜饲养成本,但却极大降低和影响了种植业收入和发展前景。因此,在优化种植业结构的基础上,需要推广秸秆舍饲养羊技术,综合开发利用农作物秸秆,提高饲草料和农作物秸秆利用率。
[Abstract]:Grazing policy implementation of Shanxi County of Youyu Province, livestock grazing for feeding by the transformation of the mode of production, reasonable adjustment of planting structure, combined with the implementation of agriculture and animal husbandry, has a strong practical significance to increase farmers' income. Based on the analysis of Shanxi County of Youyu Province in 2014 the amount of livestock forage supply and demand balance, balance of arable land, the safety of grain and oil, forage yield and nutrient demand conditions under the restrictions on Farmers' income maximization as the goal, the optimization analysis of the planting structure of grazing after Youyu county. The results showed that straw can be used as a forage crop planting ratio has been severely squeezed legume crops and other economic crops, although can minimize the cost of feeding cattle, but greatly and reduce the impact of farming income and development prospects. Therefore, based on the optimization of planting industry structure, to promote the straw Sheep raising in technology, comprehensive utilization of crop straw, improve forage and straw utilization.
