摘要
针对荒漠草原区无霜期短、水资源缺乏、饲草料匮乏等实际情况,在内蒙古达尔罕茂明安联合旗北部荒漠草原区具有灌溉条件和机械化作业条件的养殖合作社,开展了草田轮作技术研究。通过牧草和经济作物品种选择、水肥一体化栽培、适时收获等技术集成,进行“紫花苜蓿—草谷子—马铃薯—青贮玉米”的轮作示范。结果表明,该技术模式可以增加牧草产量,提高单位面积土地经济效益,是提高该地区土壤肥力和获得良好生态、社会、经济效益的有效途径,为该地区草牧业结构调整、可持续发展提供技术支撑。
In view of the actual situation of desert grassland area such as short frost-free period,insufficient water resources and deficient feed and forage supply,a rotation mode of crop and grass was explored in the livestock breeding cooperatives with irrigation and mechanized operation conditions in the northern desert grassland area of Darhan Muminggan Joint Banner in Inner Mongolia.The rotation demonstration of′alfalfa-grass millet-potato-silage maize′was carried out by integration of a series of technology,including varieties selection of herbage and economic crop,cultivation in a water and fertilizer integrated system,and timely harvesting.The results showed that this rotation mode increased the yield of herbage and improved the economic benefit of land per unit area.Furthermore,it was also an effective way to improve soil fertility and to obtain good ecological,social and economic benefits,which provided technical support for the structural adjustment and sustainable development of grassland and animal husbandry in this area.
