導(dǎo)讀: 近日,全國農(nóng)技中心組織2024年全國油菜秋冬種生產(chǎn)形勢會商,分析有利條件和不利因素,研究適期早播、適區(qū)選種、適當(dāng)密植等促進(jìn)大面積單產(chǎn)提升技術(shù)措施,全力夯實明年夏收油菜豐產(chǎn)豐收基礎(chǔ)。
【農(nóng)機(jī)網(wǎng) 熱點(diǎn)關(guān)注】 近日,全國農(nóng)技中心組織2024年全國油菜秋冬種生產(chǎn)形勢會商,分析有利條件和不利因素,研究適期早播、適區(qū)選種、適當(dāng)密植等促進(jìn)大面積單產(chǎn)提升技術(shù)措施,全力夯實明年夏收油菜豐產(chǎn)豐收基礎(chǔ)。農(nóng)業(yè)農(nóng)村部種植業(yè)管理司油料處劉武處長到會指導(dǎo),農(nóng)業(yè)農(nóng)村部油菜專家指導(dǎo)組及12個冬油菜主產(chǎn)省農(nóng)技推廣部門業(yè)務(wù)骨干參加會商。
今年油菜秋冬種生產(chǎn)形勢總體較好,具備政策環(huán)境好、農(nóng)資供應(yīng)足、騰茬空間大等有利條件。同時,也存在氣象條件復(fù)雜多變和市場預(yù)期不穩(wěn)兩個主要不利因素。
今年是鞏固提升油菜擴(kuò)種成果,深入實施單產(chǎn)提升三年行動關(guān)鍵之年,各地要緊緊圍繞油菜大面積單產(chǎn)提升目標(biāo),堅持早備耕、早播種,聚焦選良種、增密度、開三溝、防病蟲、抗災(zāi)害等環(huán)節(jié),強(qiáng)化培訓(xùn)指導(dǎo),提高技術(shù)到位率普及率,全面打牢油菜增產(chǎn)豐收基礎(chǔ)。一是適期早播,培育冬前壯苗。根據(jù)墑情和前茬收獲情況適期早播,切實擴(kuò)大適期播種比例,培育壯苗基礎(chǔ)。二是適區(qū)選種,挖掘增產(chǎn)潛力。稻油輪作區(qū)以全程機(jī)械化為導(dǎo)向,選用高產(chǎn)高油高抗、宜機(jī)收耐密植優(yōu)良新品種,構(gòu)建高產(chǎn)群體;旱地輪作區(qū)選用廣適耐瘠、耐低溫品種,減少冬前低溫凍害。三是適當(dāng)密植,構(gòu)建豐產(chǎn)群體。適期移栽的密度在0.5萬—0.6萬株/畝,遲播的可適當(dāng)提高至0.8萬株/畝;機(jī)械直播畝用種200—300克,無人機(jī)飛播畝用種300—400克,畝保苗3萬株以上,遲播地塊應(yīng)適當(dāng)增加20%—30%播種量。四是規(guī)范開溝,夯實排漬抗旱基礎(chǔ)。堅持早開溝、深開溝,避免“斷頭溝”,確保排灌暢通,減輕漬害;旱(坡)地和排水較好的稻田應(yīng)大力推廣少免耕保護(hù)性耕作,保墑防旱。五是抓早抓小,做好防災(zāi)減災(zāi)。堅持關(guān)口前移,通過種子包衣、藥劑拌種、封閉除草等措施,控制冬前病蟲草害發(fā)生基數(shù),減少后期防控難度。加強(qiáng)與氣象、水利等部門溝通協(xié)作,密切關(guān)注天氣變化,及時發(fā)布預(yù)警信息,指導(dǎo)農(nóng)戶落實防災(zāi)減災(zāi)措施,最大限度降低因災(zāi)損失。
