1 白菜籽 白菜籽可以存放2年。当年收获的种子,当年可以播种。存放2年以上的种子播种后,出苗率一般要降低20％～30％以上,且抗病力较差。存放时间越长出苗率和抗病力越差。 2 韭菜籽 种韭菜必须是当年的新籽。若种了隔年陈籽,就不容易出苗,即使个别出了苗也会很快枯萎。但如果把韭菜籽存放在0℃以下,第二年仍然可以种植。 1 cabbage seeds can be stored for 2 years. Seeds harvested the same year, the year can be planted. Stored more than 2 years after the seeds are sown, the emergence rate is generally reduced by 20% to 30% or more, and the disease resistance is poor. The longer the storage time, the worse the emergence rate and disease resistance. 2 leek seed leeks must be the new seed of the year. If you planted the next year Chen seed, it is not easy to emerge, even if individual out of the seedlings will soon wither. However, if the chives seeds stored below 0 ℃, the second year can still be planted.
