国外优良牧草品种资源是在长期人工选择和培育下形成的,具有丰富的遗傅基因和较高的生产性能。在立足于本国饲用植物资源的基础上,有计划有目的地引进国外优良牧草品种资源,这是丰富我国草种的一个重要方面。我们从1979—1983年在内蒙古锡林浩特共试种94个牧草品种,目的在于了解其适应性,为进一步鉴定、评价和利用提供依据。 Foreign forage grass species resources are formed under the long-term artificial selection and cultivation, with rich gene and high production performance. Based on the resources of our country’s foraging plants, there are plans to introduce excellent foreign forage grass resources, which is an important aspect of enriching the grass in our country. We studied 94 forage varieties from 1979 to 1983 in Xilinhot, Inner Mongolia, in order to understand its adaptability and provide the basis for further identification, evaluation and utilization.
