通过对四年生紫花苜蓿生产性能和营养品质等方面相关指标的测定研究,发掘多年生紫花苜蓿获得高产的栽培管理措施,为紫花苜蓿的大面积推广种植提供理论参考依据。苜蓿是深根性多年生优质豆科牧草,具有耐寒、耐旱、耐盐碱、耐瘠薄、适应性强等特点。种植苜蓿不仅培肥地力,而且与作物轮作还可以减少病虫草害,因此苜蓿茬种植其他作物可减少化肥、农药、除草剂等化学物质的施用量,防止潜在的环境污染。苜蓿对畜禽来说不仅适口性好,而且营养价值高,是其他牧草无可比拟的。苜蓿中钙多磷少,但磷的含量
Through the determination and research on the performance and nutritional quality of four-year alfalfa, the perennial alfalfa was explored to obtain high-yield cultivation and management measures, which provided the theoretical reference for the large-scale popularization and cultivation of alfalfa. Alfalfa is a deep root perennial superior quality forage legumes, with cold, drought, salt, barren, adaptable and so on. Planting alfalfa not only fertilizes the ground, but also crops and crop rotation can reduce pests and diseases, so planting alfalfa crop other crops can reduce chemical fertilizers, pesticides, herbicides and other chemical substances to prevent potential environmental pollution. Medicago not only palatability for livestock, but also high nutritional value, is unmatched by other pastures. Alfalfa calcium phosphorus less, but the phosphorus content
