| 摘 要： | 研究采用体外产气法评价了青海高原农牧交错区作物秸秆小麦秸按0,25:75,50:50,75:25,100的比例分别与蚕豆秸、豌豆秸、马铃薯秸和油菜秸两两组合后的发酵产气特性。结果表明,通过作物秸秆间科学的组合搭配能有效提高反刍作物对单一作物秸秆的利用率,且小麦秸分别与蚕豆秸、豌豆秸、马铃薯、油菜秸均以50:50比例组合较为合适;因此,科学地开发利用青海高原农牧交错区作物秸秆类粗饲料是解决该地区反刍家畜粗饲料资源紧缺的有效途径之一。

| Abstract: | this study was conducted using in vitro gas production techniques in order to evaluate fermentation characteristics of mixed forages,These mixtures were mixed by wheat straw at ratios of 0,25:75,50:50,75:25 and 100with beans straw,peas straw,rape straw,potato straw in farming-pastoral areas of Qinghai plateau respectively.The results showed that scientific combination of crops straw can improve ruminant utilization of single crops straw,when the mixture of wheat straw were mixed with beans straw,peas straw,rape straw and potato straw all with the proportion of 50:50 were relatively appropriate.Therefore,scientific development and utilization of abundant forages is an effective way to invovle the problems of forage shortage for ruminants in farming-pastoral areas of Qinghai plateau. |
