1、選種:選擇品種優良、顆粒飽滿的種子。2、土壤:選擇土質疏松、排水性好、肥沃的沙質土壤。3、種植:種植前將土壤進行深翻,增加土壤的疏松性和透氣性。將種子種植至土壤,覆蓋一層薄土,澆適量的水,再覆蓋一層地膜,保濕保溫。

  秋播蔥一般6-8天苗,由于當時氣溫高,苗床應注息保濕,播種后覆蓋地膜出苗時及時揭去,苗床澆水應視土壤情況而定。

  出苗后撤去地膜,由于生長期短,要加強肥水管理,生長前期進行適當間苗,中期要肥水齊攻,追肥3-4次,后期要控制肥水,防止徒長影響成活率。

  來年春天土壤化凍后要及時將覆蓋物摟出畦外,當秧苗長出3片真葉后,結合澆水追肥2-3次。同時,近青后要及時拔除雜草進行二次間苗;定植前7天左右,停止澆水,返行煉苗,提高定植成活率。
