導(dǎo)讀:“延慶模式”的成功建立,不僅在于切實(shí)可行的運(yùn)行模式,更在于先進(jìn)的農(nóng)機(jī)裝備支撐。

  【農(nóng)機(jī)網(wǎng) 地方農(nóng)機(jī)】黨的二十大報(bào)告深刻指出,人與自然和諧共生是中國(guó)式現(xiàn)代化的重要特征之一,并對(duì)推動(dòng)綠色發(fā)展、促進(jìn)人與自然和諧共生做出重要戰(zhàn)略部署。北京市委書記尹力在參加北京延慶團(tuán)審議時(shí)強(qiáng)調(diào),新時(shí)代要高質(zhì)量推動(dòng)生態(tài)涵養(yǎng)區(qū)生態(tài)保護(hù)和綠色發(fā)展,努力走生態(tài)優(yōu)先、節(jié)約集約、綠色低碳的高質(zhì)量發(fā)展之路。延慶區(qū)堅(jiān)持綠色發(fā)展,通過政府政策引導(dǎo),市場(chǎng)運(yùn)行的方式,解決了秸稈收集處理難題,同時(shí)對(duì)促進(jìn)農(nóng)民增收和農(nóng)村環(huán)境改善起到了積極作用。
 
  與往年一樣,秋玉米收獲后,田間零零散散堆放著閑置的玉米秸稈,秸稈撿拾打捆機(jī)在田間地頭忙碌作業(yè),把一座座“小山頭”變成一塊塊“小磚頭”,再由拖拉機(jī)運(yùn)離田地,這一景象會(huì)從每年11月份持續(xù)到第二年3月春播前,成捆的秸稈離田后進(jìn)行資源化處理,加工成肥料或飼料,不僅改善農(nóng)村環(huán)境,也促進(jìn)了農(nóng)民增收。近年來,北京市農(nóng)機(jī)試驗(yàn)鑒定推廣站深入開展秸稈綜合利用行動(dòng),持續(xù)探索以社會(huì)化、市場(chǎng)化為核心,以農(nóng)機(jī)合作社為橋梁,推廣“延慶秸稈撿拾打捆”利用模式,有力促進(jìn)了延慶秸稈綜合利用產(chǎn)業(yè)的發(fā)展。
 
  破解秸稈收集難題,實(shí)現(xiàn)多方共贏
 
  根據(jù)延慶區(qū)農(nóng)業(yè)生產(chǎn)特點(diǎn)和發(fā)展方向,依托農(nóng)機(jī)合作社,以市場(chǎng)化運(yùn)行、社會(huì)化服務(wù)為核心,建立了一套可持續(xù)運(yùn)行的秸稈收儲(chǔ)運(yùn)模式。該模式采用“農(nóng)戶 農(nóng)機(jī)合作社 秸稈用戶”的運(yùn)行方式,在作物收獲后,農(nóng)機(jī)合作社利用秸稈撿拾打捆機(jī)進(jìn)行秸稈打捆回收作業(yè),并支付給農(nóng)戶一定的報(bào)酬,再由農(nóng)機(jī)合作社將打捆后的秸稈集中出售給秸稈用戶,用于加工秸稈肥料、飼料或燃料等。
 
  對(duì)農(nóng)戶來說,在種下茬農(nóng)作物前要把地整理干凈,不但費(fèi)力費(fèi)時(shí)還要解決秸稈銷售問題,而該模式下,農(nóng)機(jī)合作社負(fù)責(zé)給農(nóng)戶解決凈地問題,農(nóng)戶還可以得到20元-40元/畝的秸稈銷售收入;對(duì)秸稈需求企業(yè)來說,不用購置價(jià)格較高的打捆機(jī)、粉碎機(jī)、運(yùn)輸車等設(shè)備,省去很大的設(shè)備投入資金,也不用為找秸稈來源發(fā)愁;對(duì)農(nóng)機(jī)合作社來說,由于農(nóng)業(yè)生產(chǎn)的季節(jié)性,每年的11月份至來年的2月原本是農(nóng)閑時(shí)間,沒有作業(yè)任務(wù),而秸稈打捆業(yè)務(wù)可以填補(bǔ)這部分空白,使得農(nóng)機(jī)合作社全年有活干、有收入,拓寬了業(yè)務(wù)面。
 
  先進(jìn)農(nóng)機(jī)裝備支撐,助力農(nóng)民增收
 
  “延慶模式”的成功建立,不僅在于切實(shí)可行的運(yùn)行模式,更在于先進(jìn)的農(nóng)機(jī)裝備支撐。北京市目前主推的是方捆打捆機(jī),工作時(shí)由拖拉機(jī)牽引,一次作業(yè)可將散落在地表的玉米秸稈、小麥秸稈、牧草等撿拾、成型和打捆,效率非常高。打捆機(jī)主要分為兩種,一種不帶粉碎機(jī)構(gòu),適用于秸稈經(jīng)粉碎后的撿拾打捆作業(yè),另一種帶粉碎機(jī)構(gòu),可以實(shí)現(xiàn)整稈玉米的粉碎、撿拾、打捆一體化作業(yè)。目前,市農(nóng)機(jī)試驗(yàn)鑒定推廣站示范推廣的打捆機(jī)可實(shí)現(xiàn)打捆時(shí)自動(dòng)引繩、自動(dòng)打捆、自動(dòng)切繩,還能通過對(duì)槽輪大小的調(diào)整,來改變打捆時(shí)的繩圈和秸稈捆密度,使秸稈捆不散、不凌亂,成形后的秸稈捆體積小而緊密,便于運(yùn)輸和貯存,極大地降低了運(yùn)輸成本,提高生產(chǎn)效率。
 
  “延慶模式”不僅提高了農(nóng)業(yè)廢棄物的資源利用率,而且也為農(nóng)民增收提供了新的渠道。據(jù)初步計(jì)算,農(nóng)機(jī)合作社收集秸稈成本每畝在70元左右,其中包括支付給農(nóng)戶每畝20-40元,加上機(jī)器折舊費(fèi)、人工費(fèi)、油費(fèi)、運(yùn)輸費(fèi)用等。而玉米秸稈市場(chǎng)銷售價(jià)格約為300-600元/噸,正常情況下,平均3畝地可以撿拾打捆1噸玉米秸稈,每作業(yè)1萬畝便可給農(nóng)戶帶來20 -40萬的收入,經(jīng)濟(jì)效益十分顯著。
