摘要
通过休牧70、60、50 d等不同休牧时间的设计,探讨了春季休牧对草地牧草产量和放牧绵羊生产性能的影响.结果表明,春季休牧具有良好的增产效果,其中以50 d休牧期表现较好,也比较经济可行,在锡林郭勒盟地区(试验区),以4月中、下旬开始休牧,6月中旬结束休牧为宜.
The treatments of deferred grazing in spring with deferred period of 70, 60 and 50 days respectively were designed in this experiment in order to investigate the effects of deferred grazing on the pasture productivity and the performance of grazing animals. The results showed that the forage yield and body weight of grazing sheep could be increased by deferred spring grazing. The reasonable spring resting period of grazing should be from middle or end April to middle June in region Xilingol.
