土壤選擇

　　萵(wo)筍(sun)適應性較廣(guang)，對土(tu)(tu)(tu)壤要(yao)求不太嚴(yan)格(ge)，一般的平原、坡地(di)(di)都能種(zhong)植，但要(yao)獲(huo)得較高效(xiao)益，還是要(yao)選肥(fei)沃(wo)、能排能灌的土(tu)(tu)(tu)地(di)(di)。對不太肥(fei)沃(wo)的土(tu)(tu)(tu)壤，要(yao)增(zeng)大有機肥(fei)的施用(yong)，在較為干旱(han)的田塊也可(ke)用(yong)地(di)(di)膜栽培。

　　育苗管理

　　可采用冰箱催芽或保溫瓶加冰塊催芽法。將種子浸泡4-6小時(shi)后(hou)撈起(qi)，裝(zhuang)入(ru)(ru)小布袋(dai)內，將(jiang)(jiang)小布袋(dai)內種(zhong)子表(biao)皮(pi)水甩干，再(zai)拌(ban)松(song)，放在冰箱的(de)(de)保(bao)鮮(xian)層。也可在保(bao)溫瓶內放入(ru)(ru)1-2塊冰塊，然后(hou)將(jiang)(jiang)種(zhong)子吊在瓶內（注意不要接觸下面的(de)(de)水），每隔24小時(shi)取(qu)出種(zhong)子用清水沖洗一遍，經48小時(shi)左(zuo)右即可出芽。

　　苗床育苗

　　苗床(chuang)(chuang)做成1米寬(kuan)、溝深20厘米，長度(du)隨用(yong)(yong)種量而定。把苗床(chuang)(chuang)泥土整細，用(yong)(yong)水把床(chuang)(chuang)面澆透(tou)，用(yong)(yong)沙板抹(mo)平(ping)，趁泥漿未干，按1平(ping)方米1克(ke)種子(zi)（干種）均勻撒播。在苗床(chuang)(chuang)面上做小拱(gong)棚，用(yong)(yong)雨用(yong)(yong)薄膜(mo)遮蓋或用(yong)(yong)太陽(yang)遮陽(yang)網遮蓋。苗子(zi)出真葉(xie)時，可用(yong)(yong)800倍液的多菌(jun)靈水用(yong)(yong)灑壺灑一次。熱天栽的苗子(zi)以15-25天的苗齡為宜。

　　施肥

　　施肥(fei)(fei)(fei)主(zhu)要采用一次性施足底肥(fei)(fei)(fei)。每畝地肥(fei)(fei)(fei)料(liao)配方如下：腐(fu)(fu)熟人畜糞肥(fei)(fei)(fei)3000公(gong)(gong)(gong)(gong)斤(jin)(jin)、磷(lin)肥(fei)(fei)(fei)50公(gong)(gong)(gong)(gong)斤(jin)(jin)、鉀(jia)肥(fei)(fei)(fei)20公(gong)(gong)(gong)(gong)斤(jin)(jin)、腐(fu)(fu)熟油枯100公(gong)(gong)(gong)(gong)斤(jin)(jin)、磷(lin)肥(fei)(fei)(fei)50公(gong)(gong)(gong)(gong)斤(jin)(jin)、尿(niao)素20公(gong)(gong)(gong)(gong)斤(jin)(jin)或腐(fu)(fu)熟雞鴨糞3000公(gong)(gong)(gong)(gong)斤(jin)(jin)、尿(niao)素10公(gong)(gong)(gong)(gong)斤(jin)(jin)、鉀(jia)肥(fei)(fei)(fei)20公(gong)(gong)(gong)(gong)斤(jin)(jin)。

　　及時采收

　　一定要注意在(zai)采收前10天禁止使用農藥(yao)。夏季萵筍的(de)收獲期也是抽苔(tai)最(zui)迅速的(de)時(shi)期，如果不及時(shi)采收，抽苔(tai)后品(pin)質變硬，甚(shen)至中(zhong)空。當萵筍主莖頂端與(yu)最(zui)高葉片的(de)葉尖相平時(shi)，為收獲適期。 （呂紀增）
