大葱种子是寿命较短的蔬菜种子,在常温条件下,种子寿命一般为1~2年。生产上一般采用贮藏期在一年以内的种子播种。常温贮藏1年以上的种子,因发芽率大为降低而致出苗率很低。在蔬菜生产或种子经营工作中,经常遇到新种子当年用不完,需要贮藏的问题。常温贮藏往往造成大葱种子发芽率下降幅度较大,使种子难以再次销售或应用于蔬菜生产。低温贮藏是保持大葱
Onion seeds are short-lived vegetable seeds, at room temperature, seed life is generally 1 to 2 years. The production of the general use of storage within one year seed seeded. Stored more than 1 year at room temperature seeds, due to greatly reduced germination rate caused by very low emergence rate. In vegetable production or seed management, we often encounter the problem of new seeds used up and need storage. Storage at room temperature tend to cause greater loss of germination rate of Welsh onion, so that the seeds are difficult to sell again or applied to vegetable production. Cold storage is to keep green onions
