摘　　要：呼伦贝尔草原由于长期利用不合理、部分地段受鼢鼠危害严重和无节制的开发, 造成草场出现了大面积退化、沙化。经过十几年的生产实践证明, 采用粮草混播技术和内引外联方式改良退化草场建立人工草场是目前适合于呼伦贝尔牧区东半部地区建立人工草场的最有效途径之一。运用粮草混播技术建成的人工草场产草量比同类天然草场产草量提高2 ～3 倍, 而且草群纯度高、质量好。特别是在当前治理草场生态环境和大规模退耕还草的形势下, 粮草混播是扼制草场退化、沙化, 实现自治区党委提出的畜牧业“双增双提”战略目标的好措施、好技术。Because of the long time unreasonable utilization of Hu Lun Bei Er Grassland,some parts of it had been seriously damaged by moles while the uncontrolled development caused large areas of degeneration and desertification.After over ten years production practice,it shows that the provision mix-sowing skill for the degenerative grassland improvcment is one of the most effective way suitable for the east part of HuLunBeiEr Pasture of its man-made grassland establishment.The production of man-made grassland established under mix-sowing skill is increased 2-3 times than that of the same style natural grassland,and the sheep flock is of higher purity and quality.Especially in the currcnt situation of grassland ecosystem management and large-scale of changing cultivated land back into grassland,the mix-sowing is a good measure and skill to prevent the grassland degeneration and desertification,and fulfill the strategy aim double increase and double improvement”raised by the Autonomous Region Communism Party Committee.
