導(dǎo)讀： 5月8日至10日，重慶市農(nóng)機(jī)總站會(huì)同市農(nóng)技總站、市農(nóng)機(jī)研究所、區(qū)科技局、區(qū)農(nóng)技中心及農(nóng)機(jī)站等單位有關(guān)專家，經(jīng)過(guò)3天鏖戰(zhàn)，在梁平區(qū)聚奎鎮(zhèn)進(jìn)行油菜寬壟間距機(jī)械化壟作壟收技術(shù)實(shí)驗(yàn)現(xiàn)場(chǎng)測(cè)產(chǎn)，平均畝產(chǎn)達(dá)141.2kg，較2020年全市平均畝產(chǎn)增長(zhǎng)6.8%，較以往大面積油菜聯(lián)合機(jī)收損失降低6個(gè)百分點(diǎn)。

　　【農(nóng)機(jī)網(wǎng) 科技創(chuàng)新】 5月8日至10日，重慶市農(nóng)機(jī)總站會(huì)同市農(nóng)技總站、市農(nóng)機(jī)研究所、區(qū)科技局、區(qū)農(nóng)技中心及農(nóng)機(jī)站等單位有關(guān)專家，經(jīng)過(guò)3天鏖戰(zhàn)，在梁平區(qū)聚奎鎮(zhèn)進(jìn)行油菜寬壟間距機(jī)械化壟作壟收技術(shù)實(shí)驗(yàn)現(xiàn)場(chǎng)測(cè)產(chǎn)，平均畝產(chǎn)達(dá)141.2kg，較2020年全市平均畝產(chǎn)增長(zhǎng)6.8%，較以往大面積油菜聯(lián)合機(jī)收損失降低6個(gè)百分點(diǎn)。創(chuàng)新試驗(yàn)達(dá)到預(yù)期目的，效果良好。為提高油菜種植效益、推動(dòng)油菜產(chǎn)業(yè)發(fā)展提供了新的技術(shù)路徑。
 
　　據(jù)市農(nóng)機(jī)總站李尚專家介紹：“重慶市油菜生產(chǎn)一直面臨排澇不暢、聯(lián)合機(jī)收損失嚴(yán)重、農(nóng)機(jī)農(nóng)藝融合不夠、種植效益低等問(wèn)題，嚴(yán)重制約了油菜產(chǎn)業(yè)發(fā)展。如何在不增加種植成本基礎(chǔ)上解決這些突出共性問(wèn)題，重慶市農(nóng)機(jī)總站提出了《油菜寬壟間距機(jī)械化壟作壟收技術(shù)方案》，主要有三個(gè)方面創(chuàng)新：一是寬壟間距設(shè)計(jì)，有效解決排澇和避免壟間油菜技角相互纏繞拉扯；二是壟作壟收設(shè)計(jì)，根據(jù)收割機(jī)割臺(tái)幅寬設(shè)計(jì)壟廂寬度，實(shí)現(xiàn)規(guī)范種植、對(duì)壟收割、降低機(jī)收損失；三是無(wú)須安裝豎割刀聯(lián)合機(jī)收，收割機(jī)不安裝豎割刀可大大降低縱向切割產(chǎn)生的油菜角果崩裂損失，同時(shí)可降低機(jī)具成本”。
 
　　測(cè)產(chǎn)現(xiàn)場(chǎng)，沉甸甸的油菜角鋪滿田間，試驗(yàn)田按照創(chuàng)新技術(shù)方案要求，設(shè)計(jì)成2米寬壟面，40cm、50cm兩種壟溝寬度，相鄰壟間邊行油菜相距分別達(dá)65cm、75cm，壟上按25cm×15cm行株距密植，保障每畝有效株密度達(dá)2萬(wàn)株以上，確保穩(wěn)產(chǎn)增產(chǎn)。
 
　　本次機(jī)收損失測(cè)量中創(chuàng)新探索了“切莖定莖測(cè)量法”——在選定樣本區(qū)內(nèi)將竹條(長(zhǎng)度大于壟面寬度)鋪放在壟面上，用自鎖式尼龍?jiān)鷰⒂筒烁壳o稈固定在雙層竹條架上，油菜根部莖稈貼地面用電動(dòng)剪切割，再抬升竹架將整塊布鋪放在樣本區(qū)種植面上，收獲機(jī)收割后，收集掉落到布面上的油菜籽粒進(jìn)行統(tǒng)計(jì)測(cè)算。該創(chuàng)新方法在全國(guó)屬提出，較之前全國(guó)試驗(yàn)過(guò)的收集泥土水沖法、氣吸法、鋪布條莢布條法(無(wú)序撒播無(wú)法實(shí)現(xiàn))、鋼槽收集法等更加方便精準(zhǔn)。
 
　　油菜寬壟間距機(jī)械化壟作壟收創(chuàng)新技術(shù)在全國(guó)提出，試驗(yàn)設(shè)計(jì)構(gòu)想得到了市內(nèi)同行有關(guān)領(lǐng)導(dǎo)專家的認(rèn)可。下一步，梁平區(qū)將在市農(nóng)機(jī)總站指導(dǎo)下進(jìn)一步擴(kuò)大試驗(yàn)規(guī)模，不斷探索完善該項(xiàng)技術(shù)創(chuàng)新，爭(zhēng)取為我市油菜產(chǎn)業(yè)增產(chǎn)增效增添新路徑。
