草地休牧、禁牧期家畜饲草供给模式探讨

The Research on the Forage Supplying Module on the Grassland during the Delaying and Resting Grazing Periods

针对内蒙古奈曼旗草地休牧、禁牧期草食家畜可利用饲草数量不足、质量较差、利用率偏低的问题,通过试验示范的方式推广了天然草地围封改良、补播改良、优质混播人工草地建植、高产饲料地建植等适用增产技术和青贮、微贮处理技术等提高饲草利用率的措施。综合考虑当地舍饲家畜畜群变动规律、饲草需求特点以及各类饲草资源的供给时间特性,分别提出适合全年禁牧和季节性休牧条件下草食家畜饲草均衡供给模式。

To counter the problems of Naiman Banner during the delaying and resting grazing period, such as the insufficient utilizable forage quantity, low forage quality and low utilization rate, some more efficient techniques, such as enclosure of the grassland, supplementary sowing, the establishment of the high quality artificial grassland by mixed sowing and the establishment of the high productive land for forage yield, were extended. The utilization rate of the forage was increased by some methods, such as silage and micro-silage. In addition, comprehensively considering the local altering rules of the animal flocks which is fed in houses, the traits of the forage demanding and the characteristics of supplying times of all kinds of forage resources, the module that is adapted for the balance supplying of forage under the conditions of yearly forbidding browse and seasonally forbidding browse was advanced.
