韭菜(cai)(cai)是多年生(sheng)蔬菜(cai)(cai)，可直播也可育(yu)苗(miao)移栽，并以育(yu)苗(miao)移栽居多。韭菜(cai)(cai)喜冷涼氣候，耐低(di)溫(wen)(wen)(wen)抗霜凍，地(di)上(shang)部能忍(ren)耐零下4-5℃的低(di)溫(wen)(wen)(wen)。種子發芽(ya)適宜溫(wen)(wen)(wen)度(du)15-18℃，莖葉(xie)生(sheng)長(chang)的適宜溫(wen)(wen)(wen)度(du)為12-24℃。  

韭菜的(de)(de)(de)播(bo)種(zhong)(zhong)(zhong)期，南方(fang)春播(bo)和秋播(bo)都可(ke)(ke)以（4-10月(yue)(yue)），北方(fang)為(wei)春播(bo)，華北地區一般在4月(yue)(yue)份，東北地區在4月(yue)(yue)下旬到5月(yue)(yue)。韭菜育苗(miao)(miao)中常出現(xian)出苗(miao)(miao)不(bu)整齊(qi)問題，為(wei)提高(gao)(gao)種(zhong)(zhong)(zhong)子的(de)(de)(de)發(fa)芽率(lv)，應該用(yong)新種(zhong)(zhong)(zhong)子播(bo)種(zhong)(zhong)(zhong)，并且可(ke)(ke)采用(yong)浸種(zhong)(zhong)(zhong)催(cui)芽處理（浸種(zhong)(zhong)(zhong)24小(xiao)時(shi)左右，在15-20℃的(de)(de)(de)溫(wen)度條件下，經(jing)2-3天(tian)的(de)(de)(de)催(cui)芽，待種(zhong)(zhong)(zhong)露白(bai)時(shi)即(ji)可(ke)(ke)播(bo)種(zhong)(zhong)(zhong)）。播(bo)種(zhong)(zhong)(zhong)量0.4-0.5千(qian)克/畝，播(bo)種(zhong)(zhong)(zhong)后(hou)要保(bao)持床土(tu)(tu)的(de)(de)(de)濕(shi)潤，大(da)約(yue)7-8天(tian)小(xiao)苗(miao)(miao)出土(tu)(tu)。之后(hou)的(de)(de)(de)管理要及時(shi)地間苗(miao)(miao)和清除雜草，保(bao)證(zheng)秧苗(miao)(miao)有一定(ding)的(de)(de)(de)營養(yang)面積。如(ru)果在南方(fang)多雨季節播(bo)種(zhong)(zhong)(zhong)，床土(tu)(tu)濕(shi)度較大(da)，可(ke)(ke)用(yong)干種(zhong)(zhong)(zhong)子播(bo)種(zhong)(zhong)(zhong)，而不(bu)必浸種(zhong)(zhong)(zhong)和催(cui)芽。當秧苗(miao)(miao)有15-20厘米(mi)高(gao)(gao)時(shi)為(wei)定(ding)植的(de)(de)(de)適期。
