種大蒜地濕不用澆水,大蒜在濕潤的土壤中可以很好的生長,如果澆水過多會使土壤積水,從而導致大蒜爛根,嚴重時會死亡,如果土壤濕度過大,還需將其晾曬幾天才可進行播種,避免導致蒜瓣霉變腐爛,不能發芽。大蒜屬淺根性植物,在種植時,澆水應遵循見干見濕的原則。

  大蒜的生長習性

  大蒜耐寒性較強,適宜溫度在-5~26℃的溫度中生長,蒜苗葉期耐寒能力最強,短日照而冷涼的環境下適合莖葉生長,在13小時以上的長日照及較高溫度條件下開始花芽和鱗芽的分化。

  蒜根淺,根毛多,根系吸水、肥能力較弱,所以不耐旱,在不同的生育期,大蒜對土壤濕度的要求各不相同,萌芽期要求較高的土壤濕度,促進發根發芽,幼苗期水分不能過多,防止幼苗徒長。

  大蒜在良好的光照條件之下,它的長勢才好,而且產量也多,在其生長旺期,每天需提供十個小時左右的光照,否則它的莖和葉可能徒長。
