近几年来,青岛地区圆葱种子供不应求,其主要原因是常规留种法即采用母株(鳞球)繁种,从播种育苗到采种历时3年,而且种用鳞球在贮藏中还要烂掉一部分,造成繁种成本太高,繁种收入低的现象,因此阻碍了圆葱的繁种工作。青岛市农科所观察到利用小株繁种成本很低,仅用一年时间即可采到质量相同的种子。但在大面积推广应用小株繁种技术,种子产量与母株繁种的 In recent years, Qingdao onion seeds in short supply, the main reason is that the conventional method of retention that is the use of mother plant (squash) species, from sowing seedlings to seedlings lasts 3 years, and the use of scales in the storage but also rotten Part of the loss, resulting in high cost of breeding, breeding a variety of low income, thus hindering the onion breeding work. Qingdao Agricultural Sciences observed that the use of small strains of species is very low cost, only a year can be taken to the same quality seeds. However, in a large area to promote the use of small plant breeding techniques, seed production and parent plant species
