高溫(wen)浸種、低溫(wen)貯種先將黃瓜種子浸入13℃的溫(wen)水中泡4小時，然后(hou)(hou)撈出(chu)裝入布袋，放在(zai)5℃的冰(bing)箱中冷貯一(yi)夜。第(di)2天取出(chu)用(yong)涼水沖淋，把水晾干后(hou)(hou)將布袋放入盆內備(bei)用(yong)。

高(gao)溫(wen)(wen)催芽(ya)、低(di)溫(wen)(wen)煉(lian)芽(ya)將盆內種子放在30℃~50℃的(de)高(gao)溫(wen)(wen)下催芽(ya)，24小(xiao)(xiao)時(shi)(shi)全部出芽(ya)。芽(ya)拱嘴2小(xiao)(xiao)時(shi)(shi)后降溫(wen)(wen)到20℃煉(lian)芽(ya)20小(xiao)(xiao)時(shi)(shi)。

高溫(wen)(wen)催苗、低溫(wen)(wen)蹲苗播(bo)種前室溫(wen)(wen)保持40℃，往畦土(tu)上澆開水，待土(tu)溫(wen)(wen)達40℃時，搶(qiang)溫(wen)(wen)播(bo)種已(yi)催芽的種子。在室溫(wen)(wen)40℃、土(tu)溫(wen)(wen)30℃的高溫(wen)(wen)中24~36小時后，幼苗可全(quan)部拱(gong)土(tu)。幼苗拱(gong)土(tu)后把室溫(wen)(wen)降到20℃蹲苗2天(tian)。

高溫(wen)(wen)緩苗、低(di)溫(wen)(wen)煉(lian)苗幼苗移栽后，室溫(wen)(wen)保(bao)(bao)持(chi)在(zai)30℃~35℃，土(tu)溫(wen)(wen)保(bao)(bao)持(chi)在(zai)30℃。緩苗后，白天保(bao)(bao)持(chi)在(zai)25℃，夜間保(bao)(bao)持(chi)在(zai)13~15℃。定植前10~15天，進行低(di)溫(wen)(wen)煉(lian)苗，白天溫(wen)(wen)度(du)降到(dao)17℃~20℃，夜間降到(dao)8℃~9℃。
