導(dǎo)讀:農(nóng)業(yè)農(nóng)村部種植業(yè)管理司、全國農(nóng)業(yè)技術(shù)推廣服務(wù)中心近日印發(fā)《2024年小麥大面積單產(chǎn)提升行動技術(shù)手冊》。
【
農(nóng)機網(wǎng) 科技創(chuàng)新】 農(nóng)業(yè)農(nóng)村部種植業(yè)管理司、全國農(nóng)業(yè)技術(shù)推廣服務(wù)中心近日印發(fā)《2024年小麥大面積單產(chǎn)提升行動技術(shù)手冊》。針對小麥生長中后期經(jīng)常出現(xiàn)的干熱風(fēng)、病蟲害及早衰等問題,主要通過葉面噴施植物生長調(diào)節(jié)劑、葉面肥、殺菌劑、
殺蟲劑進行防控。為了減少施藥次數(shù),通過篩選可以同步噴施的藥劑進行混配施藥,在保證防治效果的同時,還可降低生產(chǎn)成本。因此集成了小麥生長發(fā)育中后期高效管理的重要技術(shù)措施——“一噴三防”,即在小麥抽穗揚花至灌漿期,通過一次性葉面噴施植物生長調(diào)節(jié)劑、葉面肥、殺菌劑、殺蟲劑等混配液,達到防干熱風(fēng)、防病蟲、防早衰的目的,實現(xiàn)增粒增重的效果,一般能減少產(chǎn)量損失 5%—20%,確保小麥豐產(chǎn)增收。目前,已在全國各類麥區(qū)廣泛應(yīng)用,防控效果顯著,成為小麥生產(chǎn)中穩(wěn)產(chǎn)的一項重要技術(shù)。
