关于甘肃发展旱作草畜牧业生产体系的思考

在甘肃中东部旱作农业区大力推广以全膜双垄沟播玉米、全膜马铃薯为主的旱作农业技术的背景下，依据甘肃中东部旱作农业区草畜产业发展趋势和相关资料，探索提出把利用旱作农业方法种植生产大量饲草的技术体系纳入现行作物-家畜产业体系之中；利用城镇化发展形成农村人口减少的机遇，试验推广依托峁、墚、沟等天然地势地形围栏建成人工草地进行放牧；充分提升现有的旱作农业、草畜产业及依此形成的循环农业优势，在该农业区构建新型的旱作作物-旱作饲草-家畜生产体系，提升综合生产效益，促使旱作农业的“甘肃模式”升级换代。

A Consideration about Crop-forage-livestock Dryland Farming Systems in Gansu

The dryland farming technology, which was mainly about whole-film-double-ditch corn and the whole film potato, was extensively used in the middle and eastern Gansu province . Based on the development trend of grass and stock raising industry in the middle and eastern Gansu province and related information, this paper proposed a new production system of Crop-forage-livestock dryland farming systems in Gansu . The new systems should conclude the dryland farming system of forage production, the grazing system of artificially fencing grassland, and the current advantage systems, such as the dry farming, the circulation agriculture, the grass and stock raising industry . This new systems will upgrade the“Gansu model” and will promote the comprehensive production efficiency of the dryland farming . Lastly, some suggestions were put forward about policies and technologies for better using the new systems .
