Abstract:Gannan is located at the northeastern edge of the Qinghai-Tibetan Plateau, with unique climatic characteristics and diverse grassland types. In view of its strategic ecological position, the study of domestication of indigenous grass species in Gannan is of great significance to the ecological restoration of grassland and the development of animal husbandry. This paper systematically analyzes the current situation of natural grasslands in Gannan, grass species resources and their potential in ecological restoration, and at the same time discusses the scientific principles and methods of seed introduction and domestication. Combining the current situation at home and abroad with relevant experiments, adaptive management and technical strategies are proposed, aiming at improving degraded grassland through domestication of native grass species and enhancing the ecosystem service function and sustainable utilization capacity. Through the introduction and domestication of early morning glory in Gannan, it was shown that the rational selection and scientific domestication of cold and drought tolerant grass species significantly improved pasture yield and quality, and enhanced the ecological stability of grassland. This study provides a scientific basis and practical guidance for ecological restoration in Gannan and other similar areas.
