本文针对黄土丘陵区荒山草地资源遭到破坏,导致草地严重退化的实际,通过研究提出了选择优良草种,实行禾豆科牧草混播,合理施肥以及地面处理等系列技术,是建立该区人工草地的有效途径,从而可为半干旱黄土丘陵区草地资源的开发利用和建设提供科学依据。 According to the fact that the resources of waste hillside grassland in the loess hilly region have been destroyed, which leads to the serious degeneration of the grassland, a series of techniques, such as choosing the finest grass species, practicing mixed grazing of gramineous grass, reasonable fertilization and surface treatment, are put forward through the research. So as to provide a scientific basis for the development, utilization and construction of grassland resources in the semi-arid loess hilly region.
