For a long time, natural grasslands have been facing problems such as grassland degradation, livestock overgrazing, weak drought resistance, and deterioration of the ecological environment. The productivity of grasslands is extremely low, and there are significant differences in the yield and quality of forage, which cannot meet the needs of the development of animal husbandry. Artificial grassland is the best and most effective way to solve this problem. Because artificial grassland has many functions: (1) producing high-yielding and high-quality forage, solving the problem of winter and spring shortage of forage, alleviating supply and demand contradictions, and playing an important role in developing high-quality animal husbandry; (2) planting artificial grassland can reduce the pressure on the use of natural grassland, and a part of degraded grassland can be enclosed to play a good role in restoring grassland productivity; (3) artificial grassland can maintain ecological balance and effectively prevent soil erosion, thus alleviating and curbing the deterioration of the ecological environment; (4) the development of artificial grassland also plays an important role in the development and dissemination of ethnic culture. The core of artificial grassland is not planting, but the realization of multiple functions and their sustainability. There are many factors that affect stability, such as management measures and interactions between species. Among them, the selection and combination of grass species are important, but the serious invasion of weeds affects the yield, quality, and structure of grasslands. Suppressing weed invasion is the primary condition for maintaining the stability of grasslands.
