　　【農(nóng)機網(wǎng) 會展快訊】 10月24日，第二十五屆全國肥料雙交會節(jié)水增糧專題報告會在武漢成功舉辦。會議緊扣雙交會“肥水賦能 助力產(chǎn)能提升”主題，聚焦旱地高標(biāo)準(zhǔn)農(nóng)田建設(shè)、高效節(jié)水灌溉、旱作節(jié)水增糧、水肥一體化大面積提單產(chǎn)和“十五五”節(jié)水農(nóng)業(yè)發(fā)展建議等內(nèi)容，從工程建設(shè)、技術(shù)應(yīng)用、科技創(chuàng)新和發(fā)展規(guī)劃等四個層面，探討發(fā)展節(jié)水農(nóng)業(yè)支撐糧食產(chǎn)能提升的方向路徑，凝心聚智謀劃“十五五”節(jié)水農(nóng)業(yè)發(fā)展。
 
　　高標(biāo)建設(shè)筑牢節(jié)水增糧基礎(chǔ)。內(nèi)蒙古自治區(qū)農(nóng)牧廳農(nóng)田建設(shè)管理處處長林利龍研究員提出立足節(jié)水理念建設(shè)高標(biāo)準(zhǔn)農(nóng)田，要通過提升用水效率、增加有效供給、優(yōu)化水源配置來破解水資源短缺難題，不能簡單用水資源條框來限制發(fā)展。內(nèi)蒙古自治區(qū)將灌排工程作為高標(biāo)準(zhǔn)農(nóng)田建設(shè)的1號工程，聚焦三區(qū)(地表水灌區(qū)、地下水井灌區(qū)和雨養(yǎng)旱作區(qū))，“開源節(jié)水”和“深度節(jié)水”兩手并重，集成高標(biāo)準(zhǔn)農(nóng)田九大節(jié)水建設(shè)模式，為高標(biāo)準(zhǔn)農(nóng)田建設(shè)和節(jié)水農(nóng)業(yè)技術(shù)推廣有效銜接積累有效經(jīng)驗，為近年內(nèi)蒙古糧食產(chǎn)能提升奠定了堅實基礎(chǔ)。
 
　　技術(shù)應(yīng)用挖掘節(jié)水增糧潛力。遼寧省農(nóng)業(yè)科學(xué)院副院長孫占祥研究員指出，旱地作物是東北四省區(qū)近年糧食增產(chǎn)的主力軍，挖掘旱地增產(chǎn)潛力具有十分重要的戰(zhàn)略作用。當(dāng)前水資源短缺是制約旱地糧食產(chǎn)能穩(wěn)定提升的首要問題，推廣高效旱作節(jié)水技術(shù)，從節(jié)水入手打造東北旱地糧倉，具有200億斤的增產(chǎn)潛力。吉林省農(nóng)科院資環(huán)所所長王立春研究員系統(tǒng)總結(jié)了吉林發(fā)展滴灌水肥一體化技術(shù)提升糧食產(chǎn)能的實踐經(jīng)驗，提出了分區(qū)精準(zhǔn)施策、加強科技攻關(guān)、加強建后管護(hù)、強化項目引導(dǎo)等發(fā)展水肥一體化的政策建議。國際鋅協(xié)會中國項目主任樊明憲先生分享了美國高產(chǎn)玉米水肥管理技術(shù)和經(jīng)驗，總結(jié)出以水肥管理為核心的配套種植技術(shù)體系，為我國進(jìn)一步挖掘玉米種植高產(chǎn)潛力玉米單產(chǎn)提升提供了借鑒。河南心連心化學(xué)工業(yè)集團股份有限公司研究院院長劉銳杰博士分享了發(fā)展水肥一體化的實踐經(jīng)驗。為解決季節(jié)性干旱、設(shè)備適應(yīng)性及施肥與作物需求不匹配等痛點問題，心連心以設(shè)備為載體、以肥料功能及養(yǎng)分運籌為核心、以養(yǎng)分動態(tài)管理為抓手，強化示范驅(qū)動、產(chǎn)業(yè)創(chuàng)新，為作物生長提供全程水肥解決方案，助力農(nóng)業(yè)增產(chǎn)增效。
 
　　科技創(chuàng)新彰顯節(jié)水增糧智慧。智慧農(nóng)業(yè)是建設(shè)農(nóng)業(yè)強國的重要抓手，代表了農(nóng)業(yè)先進(jìn)生產(chǎn)力的發(fā)展方向。中國農(nóng)業(yè)大學(xué)水利與土木工程學(xué)院院長李云開教授系統(tǒng)介紹了以輕簡化為切入點，圍繞大田作物智慧滴灌水肥一體化開展科技創(chuàng)新，集成10余項關(guān)鍵技術(shù)與產(chǎn)品，構(gòu)建了集田間環(huán)境信息感知、數(shù)據(jù)遠(yuǎn)程傳輸、水肥智慧決策、高效精準(zhǔn)實施系統(tǒng)于一體的智慧滴灌技術(shù)體系，破解大田作物發(fā)展智慧農(nóng)業(yè)投入成本高，管理維護(hù)難，技術(shù)指導(dǎo)少等難題。甘肅海瑞達(dá)生態(tài)環(huán)境科技有限公司董事長水明海先生分享了納米保水劑研發(fā)的突破性成果。該保水劑是將天然納米級無機材料與丙烯酰胺有機雜化懸浮聚合而成，擁有納米級骨架穩(wěn)定網(wǎng)狀結(jié)構(gòu)，取得四項重大突破。與常規(guī)保水劑相比，一是吸水速率大幅提升，3分鐘達(dá)到飽和狀態(tài)。二是重復(fù)吸水能力提高數(shù)倍，10次重復(fù)吸水后仍能保持75%的吸水能力。三是跨越符合難題，可與化肥、菌肥、有機肥等融合，成為保水型功能肥料的增效劑。四是可通過無人機飛播，成為保水劑應(yīng)用的顛覆性革命。
 
　　發(fā)展規(guī)劃引領(lǐng)節(jié)水增糧未來。全國農(nóng)技中心節(jié)水農(nóng)業(yè)技術(shù)處處長吳勇正高級農(nóng)藝師指出，“十四五”期間，在黨和國家有力的政策支持下，節(jié)水農(nóng)業(yè)發(fā)展取得前所未有的歷史性成就，高效節(jié)水灌溉等農(nóng)田節(jié)水基礎(chǔ)設(shè)施建設(shè)大規(guī)模推進(jìn)，水肥一體化等節(jié)水農(nóng)業(yè)技術(shù)大面積推廣，成為糧油作物大面積單產(chǎn)提升的關(guān)鍵支撐和決定性因素。隨著高標(biāo)準(zhǔn)農(nóng)田建設(shè)、新一輪千億斤糧食產(chǎn)能提升行動等國家重大項目推進(jìn)，農(nóng)業(yè)用水需求日益增加，農(nóng)業(yè)灌溉缺口越來越大，加快發(fā)展節(jié)水農(nóng)業(yè)變得更加迫切。“十五五”節(jié)水農(nóng)業(yè)發(fā)展，要貫徹習(xí)近平總書記十六字治水方針，以提升農(nóng)業(yè)用水效率為重點，以提高糧食綜合生產(chǎn)能力為目標(biāo)，堅持高標(biāo)準(zhǔn)農(nóng)田建設(shè)與農(nóng)業(yè)節(jié)水技術(shù)推廣相結(jié)合，加快水肥一體化和旱作節(jié)水技術(shù)推廣應(yīng)用，打造節(jié)水農(nóng)業(yè)“五大糧倉”，為建設(shè)農(nóng)業(yè)強國做出節(jié)水貢獻(xiàn)。
 
　　專題報告會由全國農(nóng)技中心副主任張憲法主持，全國各級肥水技術(shù)推廣人員、科研教學(xué)單位專家學(xué)者及相關(guān)企業(yè)代表500多人參加會議。
