導讀:眼下,正是水稻播種的時節(jié),與往年不同的是,今年湖北、陜西等地區(qū)紛紛引入了采用高速氣流直播技術的全自主播撒無人機進行播種試驗,省工省力的同時,進一步提高了水稻直播的播撒效果。
【農機網 明星企業(yè)】 眼下,正是水稻播種的時節(jié),與往年不同的是,今年湖北、陜西等地區(qū)紛紛引入了采用高速氣流直播技術的全自主播撒無人機進行播種試驗,省工省力的同時,進一步提高了水稻直播的播撒效果。
陜西漢中的地塊比較分散,農戶普遍使用人工拋秧或者插秧的方式,作業(yè)效率約在 2-5 畝/天。地塊集中的大戶使用自動
插秧機,每臺插秧機的效率約 40畝/天,一臺設備需要兩到三人共同操作。
機械插秧需要完成多個工序,包括營養(yǎng)土的配制、浸種與催芽處理、播種與擺盤、苗期管理,以及移栽過程中的起秧、運輸和插栽等。
事實上,水稻種植農藝復雜、用工量大等問題,也是實現(xiàn)水稻生產全程機械化的難點。中國工程院院士、華南農業(yè)大學羅錫文教授曾指出,在我國三大糧食作物生產中,水稻生產機械化水平低。也正因此,省去了育秧、運秧和移栽等步驟的水稻直播技術,在我國適宜地區(qū)發(fā)展很快。2016年,中國已有超過30% 的水稻種植面積采用直播稻技術,但多數采用人工撒播,制約著水稻的高產穩(wěn)產。
如今,采用智能手機操控、全自主作業(yè)的極飛智能播撒無人機,每小時能夠完成80 余畝的水稻播種作業(yè),相當于 50-60 個人工的效率。以水稻種畝用量 3kg、播幅2.5m、飛行速度 6m/s、每天作業(yè)8 小時計算,極飛智能播撒無人機每天可播 640 余畝。
那么,與傳統(tǒng)的飛播設備相比,極飛智能播撒無人機是如何保證播撒效果的?極飛產品經理李杰孫為現(xiàn)場觀摩人員解釋了背后的“黑科技”秘密——依托P30 2019 款植保無人機的飛行能力,極飛智能播撒系統(tǒng)能夠將 1-10mm的種子、化肥、農藥等固體顆粒播撒到所需位置。
顆粒箱內的種子在經過十字攪拌器后,能有效分離結塊和粘連的顆粒,保證下落的均勻;
接著,種子顆粒會被滾軸式定量器均勻地分撥到播撒涵道里,進入到一個“高速氣流噴射器”;
它采用了 JetSeed™ 氣流噴射技術,通過涵道扇產生18m/s的高速氣流,且噴口經過特殊設計,能進一步加速氣流,噴撒順暢不受環(huán)境和無人機風場影響。
作業(yè)過程中,極飛智能播撒系統(tǒng)還會與飛行速度聯(lián)動,實現(xiàn)變量播撒。
極飛播撒無人機水稻直播作業(yè)
漢中地區(qū)的農技部門專家表示,對比用工成本高、播撒效率低、勞動強度大的人力播撒,極飛播撒無人機能更省工、省力地進行大面積地塊的播撒;
從作業(yè)演示及播撒效果來看,它能有效解決傳統(tǒng)飛播飛行精度低、播撒不均勻、用量不的痛點,對于推動農機規(guī)模化經營,促進農機服務組織向專業(yè)化、社會化方向發(fā)展具有重要意義。
目前,除湖北、陜西等省份以外,安徽、江西等華北地區(qū)及華南一帶,也正在開展極飛播撒無人機的水稻直播作業(yè)演示,幫助改善農業(yè)播種環(huán)節(jié),讓更、更的種植技術普惠更多農業(yè)生產者與服務者。
