栽培技術要點：

　　①選地播種：冬小麥間作(zuo)菠菜(cai)，澆(jiao)水(shui)次數要(yao)多，產菜(cai)量(liang)隨水(shui)肥(fei)(fei)水(shui)平高低而變(bian)動(dong)。因此，施底肥(fei)(fei)要(yao)足，播(bo)(bo)種(zhong)(zhong)(zhong)時(shi)墑情(qing)要(yao)好，小麥(mai)下(xia)種(zhong)(zhong)(zhong)量(liang)按(an)單(dan)作(zuo)常規用種(zhong)(zhong)(zhong)量(liang)播(bo)(bo)種(zhong)(zhong)(zhong)。菠菜(cai)播(bo)(bo)種(zhong)(zhong)(zhong)量(liang)一般每(mei)667平方米播(bo)(bo)0.5～1千克，選用耐(nai)寒、葉片(pian)肥(fei)(fei)厚的(de)尖(jian)葉有刺品(pin)種(zhong)(zhong)(zhong)，如山東諸城(cheng)菠菜(cai)、沈陽菠菜(cai)、唐山牛舌、豬(zhu)耳(er)朵(duo)等。小麥(mai)多選用耐(nai)肥(fei)(fei)水(shui)較強(qiang)的(de)品(pin)種(zhong)(zhong)(zhong)。

　　②肥水(shui)管理(li)：越(yue)冬(dong)(dong)前小(xiao)(xiao)麥(mai)、菠(bo)(bo)菜都澆(jiao)(jiao)足凍(dong)水(shui)，結合澆(jiao)(jiao)水(shui)給每667平方米菠(bo)(bo)菜施尿(niao)素5千(qian)克(ke)(ke)左右，以增(zeng)強抗凍(dong)能力(li)，促其早返(fan)(fan)青。天氣(qi)較寒冷(leng)的(de)冬(dong)(dong)小(xiao)(xiao)麥(mai)產區，還應在(zai)澆(jiao)(jiao)凍(dong)水(shui)后在(zai)菠(bo)(bo)菜畦面上撒(sa)一(yi)層草木(mu)灰或馬糞，使(shi)其安全越(yue)冬(dong)(dong)。嚴(yan)冬(dong)(dong)一(yi)過，土壤(rang)稍化凍(dong)，菠(bo)(bo)菜即(ji)可復蘇生長。這時要澆(jiao)(jiao)返(fan)(fan)青水(shui)，澆(jiao)(jiao)返(fan)(fan)青水(shui)的(de)比(bi)不(bu)澆(jiao)(jiao)返(fan)(fan)青水(shui)的(de)菠(bo)(bo)菜產量增(zeng)1倍左右。北(bei)緯37度以北(bei)地(di)區在(zai)4月中下旬澆(jiao)(jiao)水(shui)，結合澆(jiao)(jiao)水(shui)每667平方米施尿(niao)素3～5千(qian)克(ke)(ke)，或磷酸二(er)銨等復合肥5千(qian)克(ke)(ke)左右。

　　③盡早(zao)(zao)收(shou)獲(huo)(huo)(huo)菠(bo)(bo)(bo)菜(cai)(cai)：一(yi)般(ban)在(zai)(zai)小麥(mai)起身前(qian)(qian)期收(shou)獲(huo)(huo)(huo)完(wan)(wan)，收(shou)獲(huo)(huo)(huo)偏晚(wan)不(bu)利(li)(li)于小麥(mai)獲(huo)(huo)(huo)得高產。因此，菠(bo)(bo)(bo)菜(cai)(cai)的收(shou)獲(huo)(huo)(huo)期宜早(zao)(zao)不(bu)宜晚(wan)。北緯37度(du)以北地(di)區一(yi)般(ban)在(zai)(zai)春(chun)(chun)后菠(bo)(bo)(bo)菜(cai)(cai)長到6～7片(pian)葉時開始收(shou)獲(huo)(huo)(huo)，可采(cai)用疏苗(miao)(miao)采(cai)收(shou)法，即在(zai)(zai)菠(bo)(bo)(bo)菜(cai)(cai)行中收(shou)大苗(miao)(miao)留小苗(miao)(miao)，在(zai)(zai)小麥(mai)起身前(qian)(qian)期收(shou)完(wan)(wan)。不(bu)要等菠(bo)(bo)(bo)菜(cai)(cai)都長夠棵再一(yi)塊收(shou)。為使(shi)菠(bo)(bo)(bo)菜(cai)(cai)早(zao)(zao)上市(shi)，可實行地(di)膜覆(fu)蓋栽培(pei)菠(bo)(bo)(bo)菜(cai)(cai)，以利(li)(li)于提高菠(bo)(bo)(bo)菜(cai)(cai)產量和縮短麥(mai)菜(cai)(cai)共生(sheng)期。據試驗(yan)，菠(bo)(bo)(bo)菜(cai)(cai)地(di)膜覆(fu)蓋可提前(qian)(qian)上市(shi)10天左右(you)或更長，在(zai)(zai)小麥(mai)起身前(qian)(qian)即可全收(shou)完(wan)(wan)，并能增產菠(bo)(bo)(bo)菜(cai)(cai)110～170千克。覆(fu)蓋地(di)膜時間，以冬前(qian)(qian)日平均氣溫降到2℃時為好，翌年春(chun)(chun)返青期揭(jie)膜。
