摘要
苜蓿自西汉传入关中地区后,在我国经历了长期不断扩展的传播过程。其在我国历经千年而繁衍不息,除了自身具备的自然生态因素外,也与其食用价值和救荒功能、与农业生产密切相关,也与历代政府的重视和提倡等社会经济因素有关。
There has been a long course of expansion for alfalfa since it was introduced to Guanzhong area in the Western Han Dynasty. Many reasons can be used to explain the phenomenon that alfalfa can survive through thousands of years. In addition to the natural ecological factors, circumstances also play an important role. For example, alfalfa has edible value and relief function ; alfalfa is closely associated with agricultural production; the governments all promote planting alfalfa.
