【農機網 熱點關注】當前正值南方冬油菜大面積收獲季節,得益于去冬今春各地農業農村部門大力推動油菜擴種和及時跟蹤指導,適宜不同地區不同條件的油菜飛播、撒播、機播、移栽齊上陣,農機農藝緊密協作,今年又是一個油菜豐收年。如何把豐收的油菜籽及時顆粒歸倉是當前急迫的任務。
5月9日至16日,農業農村部農業機械化總站在江西省瑞昌市開展了不同種植方式條件下油菜聯合收獲、分段收獲作業效果綜合測評,總結提出了適應不同需求的油菜高效低損機收方式,有力地推動了先進適用
油菜收獲機具加快部署到生產一線。
綜合測評工作小組
據悉,油菜是我國第一大食用油料作物,常年種植面積1億畝、產量1560萬噸。人工收獲油菜費工費時,無法實現搶收騰地種稻,田間損耗很大。全國采用機械收獲油菜比例超過51%,減損就增產,推動油菜機收減損對于守穩百姓的“油瓶子”意義重大。
瑞昌市是全國油料獎勵大縣和全國主要農作物生產全程機械化示范縣,油菜種植面積20萬畝,機收率達到85%。17日,在瑞昌龍鑫農機專業合作社舉行的油菜機械收獲綜合測評情況交流與油菜機收減損作業演示,吸引了南方10個油菜主產省份農機化管理、農機鑒定和技術推廣人員,農業農村部油菜生產全程機械化專家指導組成員,有關媒體和農機企業代表,當地農業農村部門和合作社代表等約100余人現場觀摩。中國工程院院士、華中農業大學教授、國家油菜工程技術研究中心主任傅廷棟蒞臨指導。
油菜機收減損技術交流與現場觀摩
傅廷棟指出,農機化總站開展的油菜機械收獲綜合測評較為準確和全面反映出了在各種種植方式條件下,油菜聯合收獲與分段收獲在機收損失率和作業成本上的差異。測評進一步驗證和說明了,分段收獲通過提前割曬擇機撿拾具有催熟搶收騰茬優勢,分段收獲損失率比聯合收獲低,分段收獲在油菜籽成熟度和品質控制上要優于聯合收獲,但分段收獲拉長了收獲時間,兩次進地增加了作業成本,相較而言,聯合收獲更為節本便捷高效。傅廷棟認為,對于農戶小田塊宜采用聯合收獲直收方式,對于大戶規模田塊可以采用分段收獲二次收獲方式。

農業農村部農業機械化總站副站長徐振興表示,通過現場觀摩和專題調研,行業內外共同交流探討推進我國油菜機械化生產,特別是高效低損收獲的路徑和辦法,從

此次油菜機械收獲綜合測評工作得到了江蘇、安徽、湖北、江西等省農機鑒定站,九江農科院,江蘇沃得、泰州攜創等重點企業,以及瑞昌農業農村局和當地合作社的大力支持,取得了圓滿成功。領導、專家、同行一致認為,總站組織開展的綜合測評工作方法科學、測試專業、操作規范、內容豐富、數據詳實、結果有效。通過此次測評工作,全國農機鑒定系統加強了技術交流與業務合作,達到了鍛煉隊伍、提升能力、深入基層、掌握農情、展示形象、推動工作、樹立品牌的作用和效果。
