花辛苦錢買劣(lie)質農(nong)(nong)資造成減收乃至(zhi)絕收的悲劇時有發(fa)生。昨日(ri)，在春耕即(ji)將帶來(lai)之際，吉林(lin)省消(xiao)費(fei)者(zhe)協會發(fa)布消(xiao)費(fei)警示(shi)，提醒(xing)農(nong)(nong)民朋友在購買化肥等(deng)農(nong)(nong)資產(chan)品時，一定要選用國內、省內知名品牌(pai)，出現問(wen)題便于追究和(he)索賠(pei)。

    同時(shi)，注意查看包裝標識上是否有“三證(zheng)”。應選擇有登記證(zheng)號、執(zhi)行標準、生(sheng)產(chan)(chan)許(xu)可證(zheng)號的產(chan)(chan)品(pin)(pin)。不(bu)要(yao)一(yi)味追(zhui)求(qiu)低價產(chan)(chan)品(pin)(pin)，部(bu)分低價產(chan)(chan)品(pin)(pin)往往原料(liao)質量較低，養分有效性較差。

    在選購種子時，一看“兩證(zheng)一照(zhao)(zhao)”(種(zhong)(zhong)(zhong)子經營(ying)許可證(zheng)、種(zhong)(zhong)(zhong)子委(wei)托代銷證(zheng)、營(ying)業執(zhi)照(zhao)(zhao))。要(yao)到有固定(ding)經營(ying)場(chang)所的(de)合法經營(ying)單(dan)位(wei)(wei)購買(mai)種(zhong)(zhong)(zhong)子，證(zheng)照(zhao)(zhao)不全或(huo)無(wu)證(zheng)照(zhao)(zhao)的(de)單(dan)位(wei)(wei)和個人處不要(yao)購買(mai)，流動(dong)商販的(de)種(zhong)(zhong)(zhong)子不要(yao)購買(mai)；二看“審(shen)定(ding)編(bian)號”。購買(mai)時要(yao)仔細查看種(zhong)(zhong)(zhong)子的(de)包裝(zhuang)標志，是否有品(pin)種(zhong)(zhong)(zhong)審(shen)定(ding)編(bian)號，無(wu)審(shen)定(ding)編(bian)號的(de)種(zhong)(zhong)(zhong)子不要(yao)購買(mai)；三看說(shuo)明介紹(shao)。因農作(zuo)物品(pin)種(zhong)(zhong)(zhong)繁多，購買(mai)種(zhong)(zhong)(zhong)子時，要(yao)向(xiang)經銷單(dan)位(wei)(wei)認真咨(zi)詢，特(te)(te)別對新(xin)品(pin)種(zhong)(zhong)(zhong)要(yao)問清該品(pin)種(zhong)(zhong)(zhong)的(de)特(te)(te)征、適(shi)應性和栽培注意環節技術，并(bing)索(suo)取該品(pin)種(zhong)(zhong)(zhong)的(de)介紹(shao)資(zi)料(liao)。

    選購農(nong)(nong)藥(yao)(yao)(yao)時，一(yi)(yi)看(kan)(kan)農(nong)(nong)藥(yao)(yao)(yao)外(wai)在(zai)質量(liang)。合格農(nong)(nong)藥(yao)(yao)(yao)乳劑(ji)無分層(ceng)沉淀，粉劑(ji)膨松(song)不結塊(kuai)，粒劑(ji)顆粒均(jun)勻附著良(liang)好(hao)，懸(xuan)浮劑(ji)澄(cheng)清(qing)透徹(che)，搖勻快速(su)。二看(kan)(kan)生產(chan)日期。一(yi)(yi)般農(nong)(nong)藥(yao)(yao)(yao)有效(xiao)(xiao)(xiao)期為二年，超過有效(xiao)(xiao)(xiao)期藥(yao)(yao)(yao)效(xiao)(xiao)(xiao)降低(di)。三看(kan)(kan)農(nong)(nong)藥(yao)(yao)(yao)價(jia)格。有的(de)農(nong)(nong)藥(yao)(yao)(yao)價(jia)格明顯(xian)偏低(di)，同一(yi)(yi)農(nong)(nong)藥(yao)(yao)(yao)價(jia)格相差一(yi)(yi)半(ban)，顯(xian)然(ran)是不可能的(de)，因此要提(ti)防是假農(nong)(nong)藥(yao)(yao)(yao)或有效(xiao)(xiao)(xiao)成(cheng)(cheng)分含量(liang)不足的(de)農(nong)(nong)藥(yao)(yao)(yao)。四看(kan)(kan)農(nong)(nong)藥(yao)(yao)(yao)成(cheng)(cheng)分。在(zai)實際(ji)生產(chan)中(zhong)，有的(de)農(nong)(nong)民花錢買了(le)幾(ji)種(zhong)藥(yao)(yao)(yao)，但主要成(cheng)(cheng)分卻是一(yi)(yi)樣，只(zhi)不過是商品名不同，如果(guo)買回的(de)幾(ji)種(zhong)藥(yao)(yao)(yao)混用，既增加了(le)成(cheng)(cheng)本，又誘發(fa)(fa)發(fa)(fa)生藥(yao)(yao)(yao)害的(de)可能性(xing)。

    另外，購買(mai)農資一定要索取(qu)和(he)妥善保(bao)存購買(mai)憑(ping)證(zheng)和(he)發票、信譽卡、包(bao)裝物、內標簽等票證(zheng)。在(zai)農藥、種子、化(hua)肥用了以后，要把(ba)包(bao)裝袋及說明書保(bao)留(liu)一定時期（二年）。
