1989年我们从中国农业科学院引进一个冬韭品系,为进一步提高其抗寒性及产量,从1986年开始进行种子的定向选择,每年秋冬季将种子田里长势弱,抗寒性差的种株剔除,其余的混合采种。经过几年的精选繁育,现已形成了抗寒性极强,长势壮,产量高的定型品种,在当地被称为西蒲韭菜。1989年采种8130公斤,1990年招远县种植3000余亩。莱阳、龙口、莱州、牟平、芝罘等县、市(区)均已开始引种。
In 1989 we introduced a Chinese winter leek from the Chinese Academy of Agricultural Sciences, in order to further improve its cold resistance and yield, since 1986, the directional selection of seeds, the annual autumn and winter will be weak in the seed fields, cold hardy strains were removed , The remaining mixed seed. After several years of selection breeding, has now formed a strong cold resistance, growing strong, high yield stereotypes, known locally as West Po leek. In 1989, planting 8130 kilograms, Zuoyuan County in 1990 planted more than 3,000 acres. Laiyang, Longkou, Laizhou, Muping, Zhifu and other counties, cities (districts) have already begun to introduce.
