  廣東五華縣化肥農(nóng)藥雙減 農(nóng)戶(hù)增產(chǎn)增收
 
  2018年11月8日,五華縣棉洋鎮(zhèn)聯(lián)西村示范田基地迎來(lái)一片豐收,實(shí)割實(shí)測(cè)成果顯著。試驗(yàn)田通過(guò)實(shí)施,取得了四個(gè)方面成效。

  化肥減排效果明顯:農(nóng)民平均用肥減少10公斤/畝,減幅達(dá)到18%。據(jù)了解常規(guī)田每畝肥料220元,試驗(yàn)田三控肥每畝135元,每畝可節(jié)省肥料錢(qián)85元。
 
  農(nóng)藥減排效果明顯:全面推廣生物農(nóng)藥、低毒低殘留農(nóng)藥、噴霧器和統(tǒng)防統(tǒng)治等綜合防控技術(shù),使試驗(yàn)田農(nóng)藥利用率從30%提高到40%,農(nóng)藥包裝廢棄物回收率從0提高到90%,農(nóng)產(chǎn)品農(nóng)藥殘留量符合國(guó)家標(biāo)準(zhǔn)。
 
  增加農(nóng)民收入:常規(guī)田,畝產(chǎn)干谷1070市斤。試驗(yàn)田畝產(chǎn)干谷1170市斤。試驗(yàn)田比常規(guī)田畝產(chǎn)增值100斤。實(shí)實(shí)在在增加了農(nóng)民收入。
 
  改善生活環(huán)境,扮靚美麗鄉(xiāng)村:減少化肥、農(nóng)藥對(duì)水體和土壤的污染,改善河流水源質(zhì)量,提高土壤肥力和產(chǎn)出力,改善農(nóng)村生產(chǎn)、生活和生態(tài)環(huán)境,顯現(xiàn)一幅生態(tài)美的新農(nóng)村景象。
 
  廣東減量使用化肥農(nóng)藥:行業(yè)有共識(shí),上下齊發(fā)力
 
  一條條黑色的軟管鋪在菜地里,水閘門(mén)一開(kāi),抽水機(jī)從水池里抽水加壓,水從軟管上的細(xì)孔直噴而出,撒落在田間。這是記者日前在平潭四季綠蔬菜生產(chǎn)基地看到的一幕。這水不是普通的灌溉水,是融入了可溶性或液體肥料的水,可浸潤(rùn)作物根系發(fā)育成長(zhǎng)區(qū)域,把水分、養(yǎng)分按比例直接供給作物。與傳統(tǒng)施肥灌溉相比,這樣的水肥一體化設(shè)施平均每畝節(jié)水60-80立方米,節(jié)約肥料16公斤,還可以增產(chǎn)20%,即每年每畝約可節(jié)支增收2000元。
 
  而在惠州惠東縣荔龍種養(yǎng)專(zhuān)業(yè)合作社果園里,荔枝樹(shù)上掛著一塊塊黃板,表面粘附了密密麻麻的“黑點(diǎn)”,一個(gè)個(gè)“路燈”矗立在旁,成為荔枝園里一道獨(dú)特的風(fēng)景線。理事長(zhǎng)盧永泉告訴記者,誘殺害蟲(chóng)旨在降低農(nóng)藥施用量和施用次數(shù)。“之前果園一年用藥次數(shù)較高,現(xiàn)在用藥次數(shù)每年可減少3次左右。”
 
  據(jù)悉,廣東省經(jīng)過(guò)近三年的示范推廣和科普教育,化肥農(nóng)藥的減量使用已經(jīng)成為種植產(chǎn)業(yè)的常態(tài)。目前,減量增效、科學(xué)種植的理念被越來(lái)越多種植戶(hù)所接受,測(cè)土配方施肥、水肥一體化應(yīng)用、有機(jī)肥替代化肥、統(tǒng)防統(tǒng)治、綠色防控等技術(shù)日益被廣泛采用。
 
  2015年以來(lái),廣東省各級(jí)農(nóng)業(yè)部門(mén)圍繞農(nóng)業(yè)部(現(xiàn)農(nóng)業(yè)農(nóng)村部)“一控二減三基本”和化肥農(nóng)藥使用量零增長(zhǎng)行動(dòng),以推廣測(cè)土配方施肥、有機(jī)肥替代化肥技術(shù)為抓手,大力推進(jìn)化肥減量增效,并積極開(kāi)展農(nóng)藥監(jiān)督管理、農(nóng)作物病蟲(chóng)監(jiān)測(cè)預(yù)警、農(nóng)作物綠色防控和專(zhuān)業(yè)化統(tǒng)防統(tǒng)治等工作,2017年全省化肥使用量較2016年下降1.04%;農(nóng)藥使用量比過(guò)去三年的平均值減少8%,連續(xù)3年呈下降態(tài)勢(shì)。廣東已提前實(shí)現(xiàn)化肥農(nóng)藥零增長(zhǎng)。
 
  浙江湖州化肥農(nóng)藥減半 稻魚(yú)共養(yǎng)喜增收
 
  浙江湖州長(zhǎng)興縣和平鎮(zhèn)有一連片種植的水稻,今年的化肥和農(nóng)藥使用量都減少了50%,其畝均投入由之前的290元下降至100元左右。日前一核算,畝均凈收益達(dá)到3375元,比傳統(tǒng)水稻種植多了好幾倍。
 
  據(jù)農(nóng)技術(shù)人員介紹,該片水稻采用的是“蝦稻輪作—稻鴨共養(yǎng)”新模式。3月初至4月上旬,放養(yǎng)小龍蝦苗,每畝40公斤,6月中下旬開(kāi)始捕撈;6月上旬水稻育苗,7月上旬移栽;7月中旬放養(yǎng)苗鴨10只,9月底收獲鴨子;11月中旬收割晚稻,稻鴨共生期為60-70天。整個(gè)種養(yǎng)周期約9個(gè)月,創(chuàng)造了“一季小龍蝦、一季水稻、一季鴨”的種養(yǎng)模式。
 
  農(nóng)技術(shù)人員就此算了一筆精細(xì)賬:?jiǎn)我环N植晚稻“南粳46”“蘇香粳100”,畝產(chǎn)約550公斤,出米率約70%,常規(guī)稻米售價(jià)在4.28元/公斤,加國(guó)家種糧補(bǔ)貼150元,合計(jì)畝均收益1800元,去除各項(xiàng)成本,畝均利潤(rùn)為400元。而采用“蝦稻輪作-稻鴨共養(yǎng)”模式,每畝產(chǎn)“蝦稻米”280公斤,售價(jià)12元/公斤,產(chǎn)值3360元;10只鴨子計(jì)產(chǎn)值250元;小龍蝦單產(chǎn)110公斤、計(jì)產(chǎn)值4620元;加國(guó)家種糧補(bǔ)貼150元,合計(jì)收益8380元。去除各項(xiàng)成本后,畝均利潤(rùn)為3375元,農(nóng)戶(hù)增收幅度達(dá)743%,經(jīng)濟(jì)效益相當(dāng)明顯。
 
  同時(shí),這一模式還有效保護(hù)基本農(nóng)田結(jié)構(gòu),在稻田中形成新的生態(tài)循環(huán)鏈,減少化肥、農(nóng)藥施用,不僅生產(chǎn)了符合消費(fèi)導(dǎo)向、市場(chǎng)需求的“蝦稻米”、小龍蝦、塘鴨等綠色農(nóng)產(chǎn)品,生態(tài)效益也較為明顯。
 
  據(jù)湖州市農(nóng)業(yè)部門(mén)介紹,今年以來(lái),該市將稻魚(yú)綜合種養(yǎng)作為轉(zhuǎn)變農(nóng)漁業(yè)發(fā)展方式的重要抓手,大力推廣應(yīng)用“稻-鱉”“稻-小龍蝦、青蝦”“稻-蟹、鰍、蛙”等綜合種養(yǎng)模式,合計(jì)種養(yǎng)2.88萬(wàn)畝,100畝以上的種養(yǎng)基地35個(gè),綜合效益達(dá)到3億元以上。水稻平均畝產(chǎn)500公斤左右,畝均年純收入3000元以上,比傳統(tǒng)的單一種植模式增收1000多元。與池塘養(yǎng)殖相比,示范基地餌料系數(shù)減少35%以上。
