北方寒旱区羊草人工栽培技术要点

Key techniques of artificial cultivation of Leymus chinensis in northern cold and arid regions

在北方寒旱区,根据天然草原的自然资源状况、气候特点和草地利用程度等,重点研究呼伦贝尔寒旱地羊草人工建植技术,羊草人工种植对恢复草原植被、防治水土流失和改善生态环境具有重要的意义。本文将从播前准备、播种技术、田间管理和收获利用4个方面对羊草人工栽培技术进行系统的阐述。旨在发挥羊草人工草地在促进牧草业发展,缓解草畜矛盾,实现草畜平衡,有效保护草原生态,使天然草原得到永续利用,对于遏制生态环境恶化趋势,维护国家生态安全具有重要的作用,为草原生态和畜牧业增添新动能。

In the northern cold and arid regions,according to the natural resources,climate characteristics and utilization degree of natural grassland,the artificial construction and planting technology of Leymus chinensis in the cold and dry grassland of Hulunbuir was studied.The artificial planting of Leymus chinensis is of great significance for restoring grassland vegetation,preventing soil erosion and improving ecological environment.The artificial cultivation techniques of Leymus chinensis were systematically expounded from four aspects:preparation before sowing,sowing technique,field management and harvest utilization.It aimed to play an important role in promoting the development of herbage industry,alleviating the contradiction between herbage and livestock,realizing the balance between herbage and livestock,effectively protecting grassland ecology,and making the natural grassland sustainable utilization.It played an important role in curbing the deterioration of ecological environment,maintaining national ecological security,and adding new driving force for grassland ecology and animal husbandry.
