再生稻收獲機(jī)作業(yè)效果綜合測(cè)評(píng)成功舉辦

2022-08-01 09:12:00 來(lái)源:農(nóng)業(yè)農(nóng)村部農(nóng)機(jī)化總站 閱讀量:20444 評(píng)論

導(dǎo)讀:2022年7月27日—30日,農(nóng)業(yè)農(nóng)村部農(nóng)業(yè)機(jī)械化總站、湖南省農(nóng)業(yè)科學(xué)院開(kāi)展再生稻收獲機(jī)作業(yè)效果綜合測(cè)評(píng)。

  【農(nóng)機(jī)網(wǎng) 熱點(diǎn)關(guān)注】根據(jù)農(nóng)業(yè)農(nóng)村部農(nóng)業(yè)機(jī)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(jī)械化總站、湖南省農(nóng)業(yè)科學(xué)院開(kāi)展再生稻收獲機(jī)作業(yè)效果綜合測(cè)評(píng),按照性能測(cè)試、生產(chǎn)考核和專家評(píng)價(jià)等程序驗(yàn)證再生稻收獲機(jī)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(wèn)題,加快推進(jìn)再生稻生產(chǎn)全程機(jī)械化。羅錫文、陳溫福、柏連陽(yáng)、單楊4位院士及有關(guān)專家就再生稻收獲機(jī)進(jìn)行了專題研討,并提出了評(píng)價(jià)意見(jiàn)。
 
  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(kāi)花結(jié)實(shí),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(diǎn),適宜在我國(guó)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(duì)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(jī),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(jī)已成為制約再生稻快速發(fā)展的關(guān)鍵瓶頸。
 
  針對(duì)再生稻頭茬稻收獲碾壓率高、影響再生季產(chǎn)量的問(wèn)題,農(nóng)業(yè)農(nóng)村部農(nóng)業(yè)機(jī)械化總站起草了《再生稻收獲機(jī)作業(yè)效果綜合測(cè)評(píng)辦法》,組織湖南省農(nóng)機(jī)事務(wù)中心、江蘇省農(nóng)業(yè)機(jī)械試驗(yàn)鑒定站、安徽省農(nóng)業(yè)機(jī)械試驗(yàn)鑒定站技術(shù)骨干,對(duì)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(jī)開(kāi)展綜合測(cè)評(píng),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(shí)地核測(cè)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(tái),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(zhǎng)補(bǔ)短、共同提高。
 
  下一步,農(nóng)業(yè)農(nóng)村部農(nóng)業(yè)機(jī)械化總站將持續(xù)跟進(jìn)測(cè)評(píng)作業(yè)地塊再生稻長(zhǎng)勢(shì),進(jìn)一步以再生季稻谷產(chǎn)量驗(yàn)證機(jī)具低碾壓作業(yè)效果,并持續(xù)推進(jìn)再生稻收獲機(jī)改進(jìn)熟化、推廣應(yīng)用。
