大蔥種子在春季的4~5月,夏季的6~7月,秋季的10月均可播種。種植大蔥的時,需選擇健康、無病害、抗性好、產量高的種子,種植前需將其放在水中浸泡一段時間,待種子表皮脹破后,即可播種,播種前需將土壤深耕,并且還需要在土壤中加入適量的底肥。

  大蔥的種植方式

  種植大蔥的時候,需將種子均勻地撒播在土壤中,出苗前覆蓋地膜,有利于增溫、保濕,防止雨水沖刷造成土壤板結,同時防高溫為害,待種子出苗后,則需要將其移栽至大田中。

  大蔥種子發芽最適溫度18℃左右,一般播后6~8天可出苗,60%出苗后及時揭去地膜,待幼苗伸腰后可澆1次水,使子葉伸展,扎根穩苗,注意水分不能過多,以免幼苗徒長。

  大蔥整個苗期追肥1~2次,以速效復合肥為主,促使秧苗健壯生長,但注意施肥濃度不宜過高,否則會影響大蔥的生長。
