                  播種期一般在7月中旬—8月初,育苗地∴要選擇高爽通風、排水良好、土質疏松的田塊。翻耕時每667平方米施腐熟有機卐肥1000—1500kg,整平耙細,做成寬1.5m的畦(連溝)。

                  播種前,土地澆透水後撒一層幹細土,播種後再蓋一層幹細土,並在土面上蓋遮陽網以保濕,以防澆水或陣雨使土壤表面板結。出苗後及時揭去遮陽網。然後將遮陽網蓋在大棚或小環棚上遮陽育苗,在育苗期間要註意間苗、撥草和防病治蟲。當幼苗出土18d左右,有2—3片真葉時,要進行移苗,移苗前*傍晚,應澆透水,當天早晨再復澆*,下午4—5時起苗,按10×10cm移栽,或移在塑料營養缽內,移苗時要邊起苗〇、邊移栽、邊澆水、邊遮陽。用遮陽網再覆蓋遮蔭育苗,秧苗成活後,遮陽網日蓋夜揭,同時々註意澆水、追肥、撥草和防治病蟲♀害。
