贵州喀斯特山区多花黑麦草和青贮玉米轮作与利用技术

Rotation and Utilization of Lolium Multiflorum Lamk and Silage Maize in Karst Mountainous Area of Guizhou Province

贵州喀斯特山区耕地少且贫瘠,脱贫户返贫风险大,发挥有限的耕地资源,创造更多的生物量,对巩固脱贫攻坚成果和推进乡村振兴有重要意义。近年来,贵州喀斯特山区发展草牧业取得了显著成效,随之产生了畜多草少的矛盾,所以提高土地牧草产量,推进草畜平衡成为当前最为重要的任务。多花黑麦草与青贮玉米是贵州种植的主要牧草品种,但缺乏详细的生产指导技术。该文结合贵州喀斯特山区气候和土壤条件,系统详述多花黑麦草与青贮玉米轮作的适宜区域、品种选择、种子质量、种植和利用技术,指导种养殖业主开展多花黑麦草与青贮玉米轮作与利用,对提高亩产生物量和利用效率有重要意义。

The arable land is small and barren,and the risk of poverty alleviation is high in karst mountainous areas of Guizhou province.Therefore,using the limited cultivated land resources to create more biomass is of great significance for consolidating the achievements of poverty alleviation and promoting rural revitalization.In recent years,the development of grass husbandry in karst mountainous areas of Guizhou has achieved remarkable results,resulting in the contradiction of more livestock and less grass.Thus,it is the most important task to improve the yield of herbage and promote the balance of herbage and livestock.Lolium Multiflorum Lamk and Silage Maize are the main forage variety planted in Guizhou,but there is a lack of detailed production guidance technology.Combined with the climate and soil conditions in karst mountainous area of Guizhou,this paper systematically detailed the suitable area,variety selection,seed quality,planting and utilization technology of Lolium multiflorum Lamk and Silage Maize,and guide breeding owners to carry out rotation and utilization of Lolium multiflorum Lamk and Silage Maize to improve biomass and utilization efficiency.
