近年來通渭縣農業種植結構大力調整，全覆膜雙壟溝播玉米種植成為農業主導產業。隨之而來的玉米種子市場也(ye)呈現(xian)出(chu)前(qian)所(suo)未有的(de)(de)(de)繁榮，但種(zhong)(zhong)(zhong)子(zi)品(pin)(pin)(pin)種(zhong)(zhong)(zhong)五花八門，良(liang)(liang)莠不(bu)齊的(de)(de)(de)現(xian)狀也(ye)十分普遍。由于小(xiao)商販在(zai)經濟(ji)利益驅(qu)動下(xia)(xia)盲目購進銷售，從(cong)不(bu)進行試驗，示范，致使農(nong)民(min)在(zai)購種(zhong)(zhong)(zhong)時無所(suo)適從(cong),盲目聽(ting)信(xin)他人(ren)之言，購買了(le)不(bu)適宜(yi)品(pin)(pin)(pin)種(zhong)(zhong)(zhong)甚至假劣種(zhong)(zhong)(zhong)子(zi)，于是(shi)坑農(nong)害(hai)農(nong)事件時有發生(sheng)，給農(nong)民(min)造成極大損失，同(tong)時也(ye)影響了(le)全(quan)縣糧(liang)食總產(chan)(chan)的(de)(de)(de)提高。鑒于此，縣種(zhong)(zhong)(zhong)子(zi)管理站為(wei)(wei)使這一旱作(zuo)農(nong)業技術(shu)更(geng)能為(wei)(wei)糧(liang)食增產(chan)(chan)、農(nong)業增效、農(nong)民(min)增收和農(nong)村社會的(de)(de)(de)穩定作(zuo)出(chu)更(geng)大貢獻，根據全(quan)縣各(ge)(ge)鄉(xiang)鎮不(bu)同(tong)氣候條(tiao)件，試驗、示范了(le)不(bu)同(tong)區(qu)(qu)(qu)域種(zhong)(zhong)(zhong)植(zhi)(zhi)的(de)(de)(de)高產(chan)(chan)、抗(kang)(kang)旱、豐產(chan)(chan)性(xing)好、搞逆性(xing)和抗(kang)(kang)病性(xing)強的(de)(de)(de)優良(liang)(liang)品(pin)(pin)(pin)種(zhong)(zhong)(zhong)。通過(guo)廣播電視和在(zai)各(ge)(ge)鄉(xiang)鎮樹廣告牌，散發傳單(dan)等(deng)形式告知(zhi)種(zhong)(zhong)(zhong)植(zhi)(zhi)農(nong)戶。玉(yu)米(mi)品(pin)(pin)(pin)種(zhong)(zhong)(zhong)布局建議為(wei)(wei)在(zai)海(hai)(hai)拔1900-2200米(mi)區(qu)(qu)(qu)域種(zhong)(zhong)(zhong)植(zhi)(zhi)金(jin)(jin)穗3號(hao)(hao)(hao)，搭配品(pin)(pin)(pin)種(zhong)(zhong)(zhong)富隴821，墾(ken)玉(yu)10號(hao)(hao)(hao)；海(hai)(hai)拔1800-1900米(mi)區(qu)(qu)(qu)域種(zhong)(zhong)(zhong)植(zhi)(zhi)長(chang)城706、金(jin)(jin)凱5號(hao)(hao)(hao)；海(hai)(hai)拔1700-1800米(mi)的(de)(de)(de)區(qu)(qu)(qu)域種(zhong)(zhong)(zhong)植(zhi)(zhi)中玉(yu)9號(hao)(hao)(hao)、五谷704，海(hai)(hai)拔1700米(mi)以下(xia)(xia)區(qu)(qu)(qu)域種(zhong)(zhong)(zhong)植(zhi)(zhi)豫玉(yu)22號(hao)(hao)(hao)、金(jin)(jin)凱3號(hao)(hao)(hao)、先玉(yu)335等(deng)。這些(xie)都(dou)是(shi)本區(qu)(qu)(qu)域最(zui)適合的(de)(de)(de)品(pin)(pin)(pin)種(zhong)(zhong)(zhong)，平均每畝(mu)增產(chan)(chan)30-60公斤。

    科學合理的(de)品(pin)種(zhong)布(bu)局，充分(fen)發揮(hui)了(le)優良品(pin)種(zhong)增(zeng)產增(zeng)收的(de)作用(yong)，加大(da)宣傳力(li)度，引導農(nong)民(min)購(gou)種(zhong)，只有這(zhe)樣才能防止坑(keng)農(nong)害農(nong)事件發生，提(ti)高糧食(shi)總產，為通渭縣(xian)糧食(shi)增(zeng)產做(zuo)出我們應(ying)有的(de)貢獻。
