为开发利用南方草山草坡,从八十年代初国家畜牧总局协同地方有关部门在南方的一些省区进行了大面积飞播牧草工作。根据各地报导,飞播的豆科牧草全部接种了相应的根瘤菌,产草量成倍增加,饲草品质不断提高,收到了明显的社会效益与经济效益。 In order to develop and utilize the grassy slope of the southern grassland, the State Administration of Animal Husbandry conducted a large-area aerial sowing and pasture work in some provinces and autonomous regions in the south in cooperation with the local authorities in the early 1980s. According to reports from all over the world, all the aerial legumes were inoculated with the corresponding rhizobia. The yield of grass increased exponentially and the quality of the forage grass kept improving. Social and economic benefits were received.
