先把種(zhong)(zhong)(zhong)(zhong)子(zi)浸(jin)(jin)2小時(shi)后(hou)用濕沙布包裹，吊(diao)于水(shui)井或(huo)置于山洞或(huo)5～10℃的冰箱內3～4天進行低溫(wen)催芽(ya)，待大部分(fen)種(zhong)(zhong)(zhong)(zhong)子(zi)發芽(ya)后(hou)播種(zhong)(zhong)(zhong)(zhong)。或(huo)用植物激素(su)處理種(zhong)(zhong)(zhong)(zhong)子(zi)，如細(xi)胞(bao)激動素(su)100微(wei)升/升（ppm）溶(rong)液(ye)浸(jin)(jin)種(zhong)(zhong)(zhong)(zhong)3分(fen)鐘(zhong)或(huo)用赤霉(mei)素(su)5微(wei)升／升（ppm）溶(rong)液(ye)浸(jin)(jin)種(zhong)(zhong)(zhong)(zhong)6～7小時(shi)，催芽(ya)效果良(liang)好。 

生(sheng)菜(cai)喜(xi)冷涼而(er)忌高溫(wen)，其(qi)種(zhong)(zhong)(zhong)子(zi)在4℃以上開始發芽(ya)，發芽(ya)適(shi)溫(wen)為15～20℃，30℃以上高溫(wen)受抑制，因此，除(chu)高溫(wen)季節外(wai)，播種(zhong)(zhong)(zhong)生(sheng)菜(cai)種(zhong)(zhong)(zhong)子(zi)前，一(yi)(yi)般(ban)不(bu)需處理，而(er)在7～8月(yue)份，由于(yu)溫(wen)度太高，一(yi)(yi)般(ban)要進行催芽(ya)處理，方法(fa)為：先把(ba)種(zhong)(zhong)(zhong)子(zi)浸(jin)2小時后(hou)(hou)用(yong)濕(shi)沙布包裹，吊于(yu)水井或(huo)(huo)置于(yu)山(shan)洞或(huo)(huo)5～10℃的(de)冰(bing)箱(xiang)內(nei)3～4天(tian)進行低(di)溫(wen)催芽(ya)，待大部分(fen)種(zhong)(zhong)(zhong)子(zi)發芽(ya)后(hou)(hou)播種(zhong)(zhong)(zhong)。或(huo)(huo)用(yong)植物激素處理種(zhong)(zhong)(zhong)子(zi)，如細胞激動素100微(wei)升/升（ppm）溶液浸(jin)種(zhong)(zhong)(zhong)3分(fen)鐘或(huo)(huo)用(yong)赤霉素5微(wei)升／升（ppm）溶液浸(jin)種(zhong)(zhong)(zhong)6～7小時，催芽(ya)效果良好。
