红豆草(Onobrychis viciaefolia)是一种高产、优质、抗逆性强的多年生豆科牧草,最适宜在我国半干旱、干旱地区栽培。自1978年农牧渔业部拨款在甘肃农业大学建立红豆草种子繁殖基地以来,该草在我国北方各省(区)便获得迅速发展,种子需要量与日俱增,供不应求。红豆草虽然可以进行分株、扦插等营养繁殖,但要求技术、设备复杂,不便机械化作业,同时营养繁殖只具有一个或少数的基因型而易遭病害,不利于在生产中广泛
Onobrychis viciaefolia is a perennial leguminous grass with high yield, good quality and strong resistance. It is most suitable for cultivation in semi-arid and arid regions of China. Since the Ministry of Agriculture, Animal and Animal Husbandry and Fisheries approved the establishment of the seed breeding base of sainfoin seed in Gansu Agricultural University in 1978, it has been rapidly developed in various provinces (districts) in the north of our country. The demand for seeds has been growing rapidly and in short supply. Although it is possible for sainfoin to vegetatively propagate ramet, cuttings and the like, it requires complicated techniques and equipment and is not suitable for mechanized operations. Meanwhile, vegetative reproduction has only one or a few genotypes and is susceptible to diseases and is not conducive to widespread production
