大蒜栽種前需在土壤中施加有機肥,促進大蒜生長;大蒜生長期需施加適量的尿素;到了分化抽薹期大蒜對磷肥需求最多,到了鱗莖膨大期,大蒜對鉀肥需求多。大蒜生長周期的長短,會因為播種時間而不同,春季播種大蒜的生長期為90~110天,秋季播種大蒜,其生長期為220~280天。

  大蒜的介紹

  從大蒜播種至基生葉長出土面為止的時期為萌芽期,一般大蒜播種10~15田后全部發芽,萌芽期的根部主要進行縱向生長,最長根達1厘米以上,發根數多達30余條。

  從大蒜第一片真葉展開至花芽及鱗芽分化開始的時期為幼苗期,春播大蒜只需25田就可度過幼苗期,秋播大蒜包括越冬期,要經過長達5~6個月的營養生長為鱗芽和花芽分化奠定物質基礎。

  大蒜喜好冷涼,較耐低溫,要求較高日照和高溫促進花芽及鱗芽分化,大蒜生長以砂質壤土最好,在砂土中生長的大蒜辣味濃,但質地松,不耐儲藏。
