首先需要選擇健康、飽滿的萵筍種子,栽種前需將種子放在清水中浸泡24小時,然后撈出放在濕紗布上,因為秋季溫度高,不利于種子發芽,栽種前需進行低溫催芽,可以將其放在冰箱中冷藏2~3天,待萵筍種子露白后,將其栽種在適宜的土壤中,適量澆水即可。

  萵筍的生長習性

  種植萵筍需要選地勢高燥、排水良好的地塊作苗床,播前5~7天每畝施腐熟有機肥4000~5000千克或復合肥500千克作基肥,在整地前施入后深翻,整平整細,蓋上塑料薄膜等待播種。

  萵筍幼苗出土后,適當通風,白天保持床溫12~20℃,夜間5~8℃,遮陽網早揭晚蓋,2~3片真葉時間苗1次,苗距4~5厘米,移栽前5~6天,加大通風煉苗。

  萵筍開花時適當摘除部分枝,插支柱防倒伏,花期不能缺水,花謝后減少灌水,開花后20~25天,種株葉片正常發黃,種子呈褐色或銀灰色,生白色冠毛時,及時采收。
