第(di)1階段(duan)（嫁(jia)接后前3天(tian)）：密封保溫(wen)遮光保濕，使空氣濕度(du)達到(dao)飽和狀態（以塑膜上掛有水珠(zhu)為度(du)）。溫(wen)度(du)白天(tian)25-30℃，夜晚20℃左(zuo)右，不(bu)低于18℃。

第2階段（嫁接(jie)后4-6天）：此(ci)時已進入融合期，既要(yao)防止接(jie)穗凋萎，又要(yao)逐漸(jian)降低濕(shi)度(du)，掌(zhang)握在早晨和傍晚，濕(shi)度(du)較高(gao)時短(duan)時間(jian)通(tong)風(feng)(feng)排濕(shi)，并揭去遮蓋物以(yi)使嫁接(jie)苗接(jie)受散射光(guang)，做到(dao)通(tong)風(feng)(feng)排濕(shi)與(yu)增(zeng)光(guang)時間(jian)由(you)短(duan)到(dao)長。通(tong)風(feng)(feng)應兩側(ce)通(tong)風(feng)(feng)，勿兩頭(tou)通(tong)風(feng)(feng)。白(bai)天溫度(du)控制(zhi)在25℃左右，夜間(jian)18-20℃，相對濕(shi)度(du)85-90%。

第3階段（6天(tian)(tian)(tian)(tian)后(hou)至移(yi)栽前）：6天(tian)(tian)(tian)(tian)后(hou)嫁接(jie)苗(miao)(miao)新葉(xie)開始生(sheng)(sheng)長(chang)，白天(tian)(tian)(tian)(tian)氣溫以(yi)25-30℃，夜間(jian)以(yi)不(bu)(bu)低于(yu)15℃為宜，相(xiang)對濕度80-90%，同(tong)時(shi)要逐(zhu)漸(jian)增加透光(guang)(guang)時(shi)間(jian)，陰雨天(tian)(tian)(tian)(tian)不(bu)(bu)遮(zhe)光(guang)(guang)。10天(tian)(tian)(tian)(tian)后(hou)嫁接(jie)苗(miao)(miao)基(ji)本成(cheng)(cheng)活，可按常規進行(xing)管理(li)，僅(jin)在晴天(tian)(tian)(tian)(tian)中午前后(hou)短時(shi)遮(zhe)光(guang)(guang)。移(yi)栽前7天(tian)(tian)(tian)(tian)，白天(tian)(tian)(tian)(tian)氣溫22-25℃，夜晚不(bu)(bu)低于(yu)12℃，氣溫高于(yu)40℃或低于(yu)10℃均影響成(cheng)(cheng)活率。所以(yi)應做(zuo)到晴天(tian)(tian)(tian)(tian)遮(zhe)光(guang)(guang)防高溫，夜間(jian)覆膜防低溫。另(ling)外在精(jing)心管理(li)好(hao)嫁接(jie)苗(miao)(miao)溫、光(guang)(guang)、氣、水的同(tong)時(shi)，要及時(shi)摘除(chu)由砧(zhen)木(mu)葉(xie)節(jie)中萌生(sheng)(sheng)的不(bu)(bu)定芽，以(yi)消(xiao)除(chu)因芽生(sheng)(sheng)長(chang)迅速與接(jie)穗(sui)爭奪養分而影響接(jie)穗(sui)苗(miao)(miao)成(cheng)(cheng)活之隱患。但在操作時(shi)切勿損傷子(zi)葉(xie)和(he)松動接(jie)穗(sui)。
