導讀：12月6日，組織專業(yè)技術(shù)人員深入富林鎮(zhèn)，進行“大壟密植暨玉米大壟雙行單元多株品字形播種機械化密植高產(chǎn)栽培技術(shù)”和“寒地水稻旱播(水管)機械化高產(chǎn)栽培技術(shù)”培訓。

　　【農(nóng)機網(wǎng) 地方農(nóng)機】 通河縣農(nóng)業(yè)技術(shù)推廣中心農(nóng)機農(nóng)藝站，搶前抓早開啟先進適用農(nóng)機化新技術(shù)培訓，助力2025年提升全縣糧食單產(chǎn)。12月6日，組織專業(yè)技術(shù)人員深入富林鎮(zhèn)，進行“大壟密植暨玉米大壟雙行單元多株品字形播種機化密植高產(chǎn)栽培技術(shù)”和“寒地水稻旱播(水管)機械化高產(chǎn)栽培技術(shù)”培訓，鎮(zhèn)政府相關(guān)領(lǐng)導和農(nóng)業(yè)技術(shù)推廣工作人員、村(屯)干部、農(nóng)業(yè)合作社和種植大戶等近50人參加培訓。
 
　　通過培訓學習，使廣大受訓人員認識到，應用“大壟密植暨玉米大壟雙行單元多株品字形播種機械化密植高產(chǎn)栽培技術(shù)”，壟面寬壟體大，可以吸納更多雨水，減少水分蒸發(fā)量，蓄水保墑效果好、抗旱耐澇能力明顯提高，大壟種植種子早萌發(fā)早出苗，苗全苗齊苗勻苗壯，農(nóng)作物根系生育發(fā)展的活土層空間大，農(nóng)作物能夠吸取更多土壤養(yǎng)分和肥料養(yǎng)分，農(nóng)作物根系植株生長發(fā)育健壯。玉米大壟雙行單元多株品字形播種，單元間距離44㎝以上，壟間行距75㎝—80㎝，通風透光優(yōu)勢明顯，邊際效應(邊行效應)突出，有效解決玉米禿尖、早衰、穗小等問題，玉米果穗大小均勻一致，成熟進度快，籽粒飽滿，品質(zhì)優(yōu)良，單元多株提高玉米根系生命共同體活性，根系發(fā)達盤結(jié)交錯，提高抗倒伏能力，實現(xiàn)活稈成熟，促進增產(chǎn)，增產(chǎn)幅度平均達到20%左右。
 
　　應用“寒地水稻旱播(水管)機械化高產(chǎn)栽培技術(shù)”，取消泡田攪漿作業(yè)環(huán)節(jié)，保持水田耕層土壤團粒結(jié)構(gòu)不破壞，耕層土壤含氧量提高，利于水稻根系生長發(fā)育，水稻旱播水管，通過全生育期淺濕干交替節(jié)水灌溉等田間優(yōu)化管理措施，促進寒地旱直播水稻健壯生長、根系發(fā)達、穗大穗齊，實現(xiàn)活稈成熟，莖稈堅挺粗壯抗倒伏能力增強，實現(xiàn)寒地旱直播水稻穩(wěn)產(chǎn)增產(chǎn)、優(yōu)質(zhì)高效目標；應用“寒地水稻旱播(水管)機械化高產(chǎn)栽培技術(shù)”，減少水稻栽培生產(chǎn)投入，節(jié)省育苗和移栽的成本投入，極大提高生產(chǎn)效率，降低勞動強度，減少水稻栽培人力投入，節(jié)省扣棚育苗和移栽的大量人力投入，有效解決水稻育苗移栽雇工難、雇工貴的問題，穩(wěn)定農(nóng)民種糧積極性；應用“寒地水稻旱播(水管)機械化高產(chǎn)栽培技術(shù)”，節(jié)省育苗環(huán)節(jié)農(nóng)藥化肥除草劑和育苗土壤基質(zhì)的使用，節(jié)省“返青肥”的施用，減少本田化肥施用量，減少攪漿泡田用水和生育期灌溉用水20%左右，水稻機械旱直播與常規(guī)大棚育苗機械插秧對比，每公頃可以節(jié)省生產(chǎn)投入4500元左右，節(jié)約資源保護環(huán)境，是發(fā)展水稻輕簡化規(guī)?；鷳B(tài)化效益化栽培模式的有效途徑，是水稻生產(chǎn)的保護性耕作生態(tài)化栽培方式，是提高糧食單產(chǎn)保障糧食安全的有效措施。
