記者從省種子管理總站獲悉，我(wo)省將投資1.1億(yi)元實施馬鈴(ling)薯(shu)生產(chan)用種(zhong)薯(shu)安全(quan)貯藏工程(cheng)，力(li)爭用3年時間，改善(shan)馬鈴(ling)薯(shu)脫(tuo)毒種(zhong)薯(shu)貯藏條件(jian)，健全(quan)馬鈴(ling)薯(shu)脫(tuo)毒種(zhong)薯(shu)繁育(yu)體系，使全(quan)省生產(chan)用種(zhong)薯(shu)安全(quan)貯藏能力(li)達到200萬(wan)噸以(yi)上(shang)。

　　我(wo)(wo)省馬(ma)鈴(ling)(ling)(ling)薯(shu)(shu)(shu)種(zhong)(zhong)植面積(ji)和產(chan)量位(wei)居全國前(qian)列，省委、省政府通過實施(shi)馬(ma)鈴(ling)(ling)(ling)薯(shu)(shu)(shu)增產(chan)增收(shou)項目，實現了全省1000萬(wan)畝馬(ma)鈴(ling)(ling)(ling)薯(shu)(shu)(shu)脫毒(du)種(zhong)(zhong)薯(shu)(shu)(shu)全覆蓋。目前(qian)，我(wo)(wo)省年推廣1000萬(wan)畝脫毒(du)種(zhong)(zhong)薯(shu)(shu)(shu)需生(sheng)產(chan)用(yong)種(zhong)(zhong)薯(shu)(shu)(shu)150萬(wan)噸(dun)左右(you)，常年生(sheng)產(chan)脫毒(du)種(zhong)(zhong)薯(shu)(shu)(shu)200萬(wan)噸(dun)以(yi)上(shang)，由于生(sheng)產(chan)用(yong)種(zhong)(zhong)薯(shu)(shu)(shu)貯藏以(yi)農戶分散(san)的土(tu)坑(keng)、井窖、土(tu)窯(yao)洞(dong)為主，使馬(ma)鈴(ling)(ling)(ling)薯(shu)(shu)(shu)產(chan)生(sheng)腐爛(lan)、凍害(hai)、發芽、失(shi)水等問(wen)題，造成馬(ma)鈴(ling)(ling)(ling)薯(shu)(shu)(shu)損失(shi)率達15%至30%，年損失(shi)種(zhong)(zhong)薯(shu)(shu)(shu)約(yue)2萬(wan)噸(dun)。以(yi)每噸(dun)種(zhong)(zhong)薯(shu)(shu)(shu)售價3000元計算，造成的經濟損失(shi)在6000萬(wan)元以(yi)上(shang)。

　　對此，省農(nong)(nong)業科學院農(nong)(nong)產品(pin)貯(zhu)(zhu)藏加工(gong)研究(jiu)所經(jing)(jing)多年研究(jiu)，設計出擁(yong)有自主(zhu)知識產權的(de)新型(xing)農(nong)(nong)戶貯(zhu)(zhu)藏庫窖建造(zao)模式(shi)(shi)和傳統(tong)農(nong)(nong)戶貯(zhu)(zhu)藏窖改(gai)造(zao)模式(shi)(shi)，經(jing)(jing)試驗表明，與傳統(tong)貯(zhu)(zhu)藏窖相(xiang)比，溫(wen)度降(jiang)低(di)1.2攝氏(shi)度，濕度降(jiang)低(di)7.4%，腐爛率降(jiang)低(di)30%以上。通(tong)過在安(an)定區、臨洮縣等地試點，成(cheng)(cheng)功改(gai)造(zao)農(nong)(nong)戶貯(zhu)(zhu)藏窖40多個(ge)，輻射帶(dai)動農(nong)(nong)戶改(gai)造(zao)貯(zhu)(zhu)藏窖100多個(ge)。同時，研究(jiu)取得國內領先的(de)種薯(shu)貯(zhu)(zhu)藏保鮮(xian)(xian)技術，目前(qian)已形(xing)成(cheng)(cheng)集馬鈴(ling)薯(shu)采收、預貯(zhu)(zhu)、藥劑處理、環(huan)境控制技術于一體的(de)全套(tao)馬鈴(ling)薯(shu)種薯(shu)貯(zhu)(zhu)藏保鮮(xian)(xian)技術。

　　我省實施馬(ma)鈴薯(shu)(shu)(shu)(shu)生產(chan)用種(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)安全貯藏(zang)工程，將(jiang)大(da)力推廣(guang)新型貯藏(zang)庫窖(jiao)(jiao)模(mo)式和種(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)貯藏(zang)保鮮技術。在(zai)全面完成245個1000噸(dun)一級種(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)貯藏(zang)庫建(jian)設的基(ji)礎(chu)上，從2011年至(zhi)2013年，鼓勵種(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)生產(chan)企業、馬(ma)鈴薯(shu)(shu)(shu)(shu)專業合作社、種(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)生產(chan)大(da)戶(hu)新建(jian)1000噸(dun)以(yi)上種(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)貯藏(zang)庫(窖(jiao)(jiao))90座，改造農(nong)(nong)戶(hu)3至(zhi)50噸(dun)貯藏(zang)窖(jiao)(jiao)3.2萬(wan)(wan)至(zhi)5.27萬(wan)(wan)座，培訓種(zhong)(zhong)(zhong)薯(shu)(shu)(shu)(shu)貯藏(zang)農(nong)(nong)戶(hu)5500余(yu)戶(hu)，輻射帶動3萬(wan)(wan)余(yu)戶(hu)。  (王朝霞)
