馬鈴(ling)薯(shu)苗(miao)期(qi)(qi)管理是(shi)馬鈴(ling)薯(shu)田間管理的關鍵(jian)階段(duan)，是(shi)奠定豐產基礎的關鍵(jian)時(shi)期(qi)(qi)。它(ta)直(zhi)接關系著馬鈴(ling)薯(shu)后期(qi)(qi)的生長，馬鈴薯苗期管理的重點是在保證全(quan)苗的基礎上,促進根系發育、培育壯(zhuang)苗,達到苗齊、苗壯(zhuang)。

很多(duo)種植(zhi)戶(hu)也意(yi)識到馬鈴(ling)(ling)薯(shu)(shu)(shu)苗(miao)期(qi)管理(li)(li)的(de)重要性。但是近幾(ji)年，馬鈴(ling)(ling)薯(shu)(shu)(shu)出苗(miao)弱、慢、不(bu)齊(qi)的(de)現象非常明顯，并不(bu)利于種植(zhi)戶(hu)進(jin)行(xing)苗(miao)期(qi)管理(li)(li)。那馬鈴(ling)(ling)薯(shu)(shu)(shu)出苗(miao)不(bu)齊(qi)的(de)原因(yin)是什(shen)么？我們又該如(ru)何解決呢(ni)？

馬鈴薯出(chu)苗不齊的(de)原因：

一(yi)、 種薯質量差

    種(zhong)(zhong)(zhong)植戶盲目選擇種(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)，種(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)未(wei)進行嚴格的質量(liang)監督(du)及(ji)檢查(cha)，種(zhong)(zhong)(zhong)植戶購(gou)買的種(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)質量(liang)差，病蟲害較多；另(ling)外種(zhong)(zhong)(zhong)植戶在(zai)選種(zhong)(zhong)(zhong)時(shi)未(wei)挑出(chu)帶病種(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)，在(zai)種(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)切塊(kuai)時(shi)未(wei)進行消毒，導致薯(shu)(shu)(shu)(shu)塊(kuai)腐爛(lan)，種(zhong)(zhong)(zhong)植后(hou)薯(shu)(shu)(shu)(shu)塊(kuai)不能正(zheng)常出(chu)苗。

解決辦法(fa)：

選擇正規廠家(jia)生產的(de)(de)、質(zhi)量(liang)經過嚴格檢測的(de)(de)優質(zhi)脫(tuo)毒種(zhong)薯；選種(zhong)時(shi)，剔(ti)除帶(dai)病種(zhong)薯；在切(qie)種(zhong)時(shi)，切(qie)刀(dao)要進行消毒，防止種(zhong)薯帶(dai)菌相互傳染。

二、催芽不當

    早春馬鈴薯(shu)(shu)栽(zai)植前(qian)需要進行催(cui)芽(ya)(ya)，但種(zhong)植戶在催(cui)芽(ya)(ya)的過程(cheng)中，催(cui)芽(ya)(ya)的時(shi)間掌控不好(hao)，導(dao)致馬鈴薯(shu)(shu)的芽(ya)(ya)長短不一(yi)；另外(wai)，在催(cui)芽(ya)(ya)時(shi)，由(you)于溫(wen)濕度控制不好(hao)，導(dao)致芽(ya)(ya)細弱而長，播種(zhong)時(shi)芽(ya)(ya)易斷裂，也(ye)會導(dao)致馬鈴薯(shu)(shu)出芽(ya)(ya)不齊。
