冬季辣椒育苗期間
，經常會突然受到寒流的攻擊
，溫度驟然下降，秧苗容易受凍害。如果溫度是遲緩下降，則秧苗不易結冰受凍；如(ru)溫(wen)度(du)固(gu)然(ran)不(bu)是(shi)太(tai)低(di)
，但(dan)低(di)溫(wen)延(yan)續(xu)時(shi)間(jian)很(hen)長(chang)
，特(te)別(bie)是(shi)低(di)溫(wen)與(yu)陰(yin)雨(yu)相(xiang)伴(ban)同(tong)
，秧(yang)苗(miao)也(ye)很(hen)容(rong)易(yi)發(fa)生(sheng)凍(dong)害(hai)。秧(yang)苗(miao)受(shou)凍(dong)害(hai)的(de)輕(qing)重(zhong)，還(hai)與(yu)低(di)溫(wen)過(guo)後(hou)氣(qi)溫(wen)回(hui)升(sheng)的(de)快(kuai)慢(man)有(you)關(guan)。如(ru)果(guo)升(sheng)柔(rou)和(he)解(jie)凍(dong)太(tai)快(kuai)，秧(yang)苗(miao)組(zu)織(zhi)易(yi)脫(tuo)水(shui)幹(gan)涸(he)，造(zao)成(cheng)死(si)苗(miao)。辣(la)椒(jiao)苗(miao)防(fang)凍(dong)辦(ban)法(fa)有(you)以(yi)下(xia)幾(ji)方(fang)麵(mian)。

改良育苗方法利用人工控溫育苗方法，如電熱溫床和工廠化育苗等，是解決秧苗受凍問題的基本辦法。

合理施肥增施磷鉀肥，苗期使用抗寒劑。秧苗噴施0。5％―1％的紅糖或葡萄糖水，可加強抗寒力。在3―4葉期噴施2次（間隔7天）0。5％氯化鈣溶液
，可加強抗寒性。
