  【農機網 科技創新】4月19日,農業農村部農作物生產全程機械化專家指導組甘蔗專業組在組長、華南農業大學區穎剛教授的帶領下,成員華南農業大學劉慶庭教授、福建農林大學張華研究員、云南省農業機械推廣站鄧慶高級工程師、海南省農業機械鑒定推廣站王文研究員、華南農業大學武濤副教授等,參加了廣西甘蔗分步式收獲機具裝備研發推廣工作研討會視頻會議,開展了相關調研工作,并提出了建議和意見。廣西農業機械化服務中心副主任范軍燦作總結。
 

 

廣西農機化服務中心匯報甘蔗分步式機收情況
 

 

甘蔗專家組參加研討會視頻會議
 
  來自廣西農業機械化服務中心各業務部門、南寧市農業農村局、柳州市農機中心的負責同志和業務骨干以及甘蔗收獲機械生產企業代表40余人參加了研討會。廣西壯族自治區農業機械化服務中心匯報了“糖料蔗分步式收獲機械在廣西鑒定、運用情況與研發方向探討”“廣西甘蔗分步式機收技術路線”,廣西合浦縣惠來寶機械制造有限公司、湖北利匯智能農機裝備科技有限公司等相關企業代表介紹了分步式收獲機具的研發推廣使用情況。
 
  當前廣西甘蔗聯合收獲機保有量為2588臺,預計2021/2022榨季聯合機收量為200萬噸,聯合機收水平約為4%,聯合收獲機作業量僅為170畝/臺。廣西壯族自治區人民政府提出,要切實轉換思路,把提高甘蔗生產全程機械化工作重點由單純推廣“一步法”聯合機收作業向多種作業模式并重轉變,大力破解甘蔗機收率低的瓶頸問題。
 
  本次研討會明確了推進“分步式”收獲機具裝備推廣應用的可行性和重要性。分步式機收對比聯合機收有以下優勢,一是對于糖廠,分步式機收可以為糖廠提供與人工收獲品質相當的整稈蔗莖,總含雜率不超過3%,與大部分糖廠現有制糖工藝相匹配,不需要糖廠進行技改設備升級,糖廠接受度高。二是對于蔗地,各種類型且造價低廉的割鋪機、割堆機可以適應各種地塊收割要求,且效率遠高于人工,使用成本也低,解決了大中型甘蔗聯合收割機下不了地、下地不賺錢的難題。三是對于蔗農,割鋪機、割堆機收割損失小,不碾壓蔗蔸、不影響次年宿根生長,無蔗葉殘留,便于破壟施肥等宿根管理,除雜(剝葉)后糖廠扣雜低,蔗葉可綜合化利用,增加額外收入,綜合效益好。四是對于作業者,分段式收獲包括割鋪、田間集運、除雜、裝車進廠四個作業環節,農戶可以自由選擇其中一個或幾個部分交由機收服務隊作業,方式較為靈活,可以帶動農機作業戶增收。
 
  分步式機收主要有兩種技術路線,一是田間剝葉、割鋪(堆)、田間轉運入廠。二是田間割鋪(堆)、田間轉運、集中剝葉除雜、裝車入廠。目前“分步式”機收模式已有雛形,但仍存在不足,如田間剝葉機需要寬行距種植要求,嚴重彎曲倒伏甘蔗破損率較高,割鋪轉運作業銜接不順、效率不高,集中剝葉除雜裝置還不太成熟、輔助人工較多、作業效率偏低等。
 
  通過此次研討會,達成以下共識。一是,小型、多步驟的“分步式”機收模式是符合廣西實際的甘蔗機械化好路子,為用戶在聯合機收和人工傳統收獲之外提供一種選擇,可以提高丘陵山區和小地塊蔗地機收水平。二是,各級農機部門要提高政治站位,制定相關政策、加大推廣力度,全力支持“分步式”機收方式,生產模式要精簡成熟,減少作業工序、減少輔助人工,以收定種推進標準化、規范化、宜機化種植。三是,各有關農機企業要找準著力點,優化創新核心技術,攻堅克難,研發一批適用、好用的“分步式”收獲機具裝備,機具裝備要高質高效,更加便捷、更加智能、更加可靠。
