　　【農(nóng)機網(wǎng) 熱點關(guān)注】根據(jù)農(nóng)業(yè)農(nóng)村部農(nóng)業(yè)機械化管理司部署，2022年7月27日—30日，農(nóng)業(yè)農(nóng)村部農(nóng)業(yè)機械化總站、湖南省農(nóng)業(yè)科學(xué)院開展再生稻收獲機作業(yè)效果綜合測評，按照性能測試、生產(chǎn)考核和專家評價等程序驗證再生稻收獲機可靠性、適用性、安全性，著力解決再生稻頭茬稻收獲碾壓率高、影響再生季產(chǎn)量問題，加快推進(jìn)再生稻生產(chǎn)全程機械化。羅錫文、陳溫福、柏連陽、單楊4位院士及有關(guān)專家就再生稻收獲機進(jìn)行了專題研討，并提出了評價意見。
 
　　再生稻是指頭季水稻收獲后，利用稻樁上存活的休眠芽，采取一定栽培管理措施使之萌發(fā)為再生蘗，進(jìn)而抽穗、開花結(jié)實，再收獲一季水稻的種植模式。再生稻省去再生季耕整地、育秧插秧環(huán)節(jié)，具有一種兩收、省工節(jié)本、增產(chǎn)增效、再生季稻米品質(zhì)好等優(yōu)點，適宜在我國南方稻區(qū)種植一季稻熱量有余、種植雙季稻熱量又不足的地區(qū)應(yīng)用。與常規(guī)水稻種植模式相比，再生稻頭季收獲需要盡量減少對稻樁損傷，促進(jìn)再生季稻芽早萌發(fā)、多分蘗。目前再生稻收獲主要采用常規(guī)履帶式全喂入谷物聯(lián)合收獲機，頭季收獲綜合碾壓高，留茬成活率低，嚴(yán)重影響再生季產(chǎn)量，缺乏成熟的再生稻專用收獲機已成為制約再生稻快速發(fā)展的關(guān)鍵瓶頸。
 
　　針對再生稻頭茬稻收獲碾壓率高、影響再生季產(chǎn)量的問題，農(nóng)業(yè)農(nóng)村部農(nóng)業(yè)機械化總站起草了《再生稻收獲機作業(yè)效果綜合測評辦法》，組織湖南省農(nóng)機事務(wù)中心、江蘇省農(nóng)業(yè)機械試驗鑒定站、安徽省農(nóng)業(yè)機械試驗鑒定站技術(shù)骨干，對湖南農(nóng)科院、江蘇大學(xué)、華中農(nóng)大、華南農(nóng)大等科研院所和生產(chǎn)企業(yè)已研發(fā)試制的新型再生稻收獲機開展綜合測評，在統(tǒng)一條件、統(tǒng)一方法、統(tǒng)一流程、統(tǒng)一標(biāo)準(zhǔn)條件下，實地核測作業(yè)速度、損失率、含雜率、破碎率、割茬高度合格率、最小離地間隙、平均接地壓力、直行碾壓率等作業(yè)性能指標(biāo)和作業(yè)效率、單位燃油消耗量等經(jīng)濟(jì)性能指標(biāo)，為研發(fā)和生產(chǎn)單位搭建“大比武”平臺，推進(jìn)不同研發(fā)主體和制造主體之間學(xué)習(xí)交流、相互借鑒、取長補短、共同提高。
 
　　下一步，農(nóng)業(yè)農(nóng)村部農(nóng)業(yè)機械化總站將持續(xù)跟進(jìn)測評作業(yè)地塊再生稻長勢，進(jìn)一步以再生季稻谷產(chǎn)量驗證機具低碾壓作業(yè)效果，并持續(xù)推進(jìn)再生稻收獲機改進(jìn)熟化、推廣應(yīng)用。
