導(dǎo)讀:我國作為玉米的生產(chǎn)和消費大國,自新中國成立以來,產(chǎn)量和播種面積逐年遞增,目前我國玉米種植面積約4100萬公頃。
【農(nóng)機網(wǎng) 地方農(nóng)機】玉米是我國三大糧食作物之一,具有食用、飼用和工業(yè)加工等多種用途,擁有廣泛的利用價值和較好的經(jīng)濟(jì)效益,在全國31個省市自治區(qū)都有種植,作為糧、經(jīng)、飼兼用的作物,對整個國民經(jīng)濟(jì)發(fā)展有著巨大的影響。我國作為玉米的生產(chǎn)和消費大國,自新中國成立以來,產(chǎn)量和播種面積逐年遞增,目前我國玉米種植面積約4100萬公頃,但隨著工業(yè)化的不斷推進(jìn),加工業(yè)、畜牧業(yè)等產(chǎn)業(yè)對玉米需求的逐漸增大,玉米的消費量也呈現(xiàn)逐年遞增的趨勢,為了滿足玉米的消費需求,應(yīng)當(dāng)大力發(fā)展玉米生產(chǎn),在有限的種植面積內(nèi),提升玉米單位面積產(chǎn)量。保障糧食生產(chǎn)穩(wěn)定發(fā)展的關(guān)鍵是玉米生產(chǎn),玉米生產(chǎn)的快速發(fā)展對保障糧食安全、飼料安全和促進(jìn)玉米產(chǎn)業(yè)的健康發(fā)展有著十分重要的作用。
玉米制種是玉米產(chǎn)業(yè)的重要環(huán)節(jié)之一,影響著玉米產(chǎn)業(yè)的發(fā)展,保證著良種安全,其中精量播種、去雄與檢測、果穗低損收獲技術(shù)等過程均需要機械化作業(yè)生產(chǎn),但目前各環(huán)節(jié)均存在機械化水平低的難題,絕大多數(shù)存在著技術(shù)落后、作業(yè)效果差的問題,尤其是去雄與收獲環(huán)節(jié),農(nóng)機產(chǎn)品和玉米制種技術(shù)的匹配程度不好,并且玉米制種農(nóng)藝要求與普通玉米生產(chǎn)農(nóng)藝要求不同,因此,急需加大制種玉米去雄與收獲環(huán)節(jié)配套機械研制開發(fā)步伐,加快去雄與收獲環(huán)節(jié)配套機械科研成果從樣機到產(chǎn)品的轉(zhuǎn)換,將新技術(shù)、新機具推廣進(jìn)行合理的配套并實現(xiàn)科學(xué)運營,對促進(jìn)玉米生產(chǎn)和科技水平雙提升具有重要意義。
一、發(fā)展與現(xiàn)狀
甘肅省酒泉市晝夜溫差大,空氣純凈,干旱少雨,光熱資源豐富,十分有利于作物的光合作用和種子干物質(zhì)積累;境內(nèi)有祁連山雪水匯集形成的疏勒河、黑河、哈爾騰河三大水系,多年平均徑流量為332億立方米,井河灌溉互補,綠洲戈壁相間,具有天然隔離條件,災(zāi)害天氣少,具備種子生產(chǎn)的獨特優(yōu)異條件,被業(yè)內(nèi)人士譽為“天然種子加工廠”“種子生產(chǎn)黃金帶”。近年來,酒泉市依托得天獨厚的地理氣候條件和自然資源稟賦,積極推進(jìn)制種玉米示范基地建設(shè),目前,全市玉米制種面積達(dá)到23.42萬畝,制種玉米已成為全市發(fā)展現(xiàn)代農(nóng)業(yè)的支柱產(chǎn)業(yè)和優(yōu)勢產(chǎn)業(yè)。眾所周知,制種玉米全程機械化是涵蓋玉米品種選育、品種試驗、制種生產(chǎn)、種子加工等多環(huán)節(jié)的系統(tǒng)工程,從配套技術(shù)方面來看,目前酒泉市玉米制種還處于傳統(tǒng)向現(xiàn)代轉(zhuǎn)變的過程當(dāng)中,包括育種理念、育種材料、育種技術(shù)、種子生產(chǎn)機械化的配套技術(shù)體系尚未完全形成,機械化生產(chǎn)在技術(shù)力量、機具質(zhì)量及性能方面難以滿足高質(zhì)量種子的生產(chǎn)需求,這一系列因素制約著制種機械化全程、全產(chǎn)業(yè)鏈生產(chǎn)。從種業(yè)生產(chǎn)過程來看,耕整地→施肥→播種→植保→收獲→種子脫粒→種子脫水→種子篩選分級→種子包衣→種子儲存和運輸,整個制種過程機械化程度發(fā)展不充分、不均衡,有的環(huán)節(jié)還處于人工作業(yè)狀態(tài),嚴(yán)重制約著我市玉米種業(yè)高質(zhì)量發(fā)展。調(diào)查顯示,全市制種玉米耕整地、播種環(huán)節(jié)配套機具保有量大,耕整地、
播種機擁有量分別達(dá)到16000臺、4200臺,在耕整地和播種環(huán)節(jié)機械化率達(dá)到100%;田間管理環(huán)節(jié)配套機具品類繁多,鋪膜
施肥機、撒肥機、
噴霧機、電動打藥機、無人植保機等機械應(yīng)用普及率高,機械化率達(dá)到98%以上。田間運轉(zhuǎn)環(huán)節(jié)主要以中小型拖拉機及農(nóng)用運輸車進(jìn)行田間運輸,全市各類運輸裝備保有量大,田間轉(zhuǎn)運機械化水平達(dá)到100%;種子加工環(huán)節(jié)機械裝備配套齊全,剝皮、脫粒、除塵、干燥、包衣、輸送、倉儲等環(huán)節(jié)全部實現(xiàn)了機械化。
二、問題與癥結(jié)
酒泉市制種玉米實現(xiàn)全程機械化存在的問題主要集中在抽雄與收獲這兩個關(guān)鍵生產(chǎn)環(huán)節(jié),抽雄與收獲機械裝備供給不足是制約提高制種玉米生產(chǎn)機械化水平的主要短板,是制種玉米產(chǎn)業(yè)全程機械化發(fā)展的主要矛盾和矛盾的主要方面。玉米制種業(yè)是典型的勞動密集型產(chǎn)業(yè),目下農(nóng)村勞動力緊缺已成為玉米制種產(chǎn)業(yè)發(fā)展的重要制約“瓶頸”之一。調(diào)查顯示,2020年人工收獲制種玉米工價為450~500元/畝,2021年漲到了580~600元/畝,主要是50歲以上的勞動力,且只摘棒子,不割桿,不轉(zhuǎn)運,不脫粒,而機械收獲作業(yè)每畝收費90~100元,兩者相差近500元。盡管目前酒泉市擁有玉米收獲機械近800臺,但均為大田玉米收獲機械,摘穗型收獲機械存在剝皮不凈、損傷果穗的情況;因為制種企業(yè)在要求田間管理環(huán)節(jié)保證種子純度的同時,在收獲環(huán)節(jié)對種子胚乳的保護(hù)要求極高,采用籽粒型收獲機械作業(yè)達(dá)不到玉米種子低破碎率、低損失率的高要求,所幸2022年甘肅省農(nóng)業(yè)農(nóng)村廳農(nóng)機化處安排資金100萬元,由甘肅農(nóng)業(yè)大學(xué)機電工程學(xué)院(甘肅省農(nóng)業(yè)裝備協(xié)同創(chuàng)新研發(fā)中心) 承擔(dān)臥式割臺制種玉米聯(lián)合收獲機研制項目,研制4行臥輥式低損摘穗剝皮收獲機,力求玉米收獲總損失率≤3%,籽粒破碎粒≤0.6%,以期早日實現(xiàn)制種玉米快速輕簡機械化收獲,目前該項工作已經(jīng)有了實質(zhì)性進(jìn)展。
在制種玉米抽雄機械裝備方面,雖然制種玉米企業(yè)培育的種子品種繁多,且栽培規(guī)格不統(tǒng)一,而一些制種玉米品種為延長授粉期,父本、母本種植不同期,父本播種也要間隔一定時間,這樣對于抽雄作業(yè)造成很大影響,但目前酒泉市抽雄機械已有相關(guān)機型,酒泉奧凱種機股份有限公司研發(fā)生產(chǎn)的OK104-3CX大型制種玉米抽雄機通過農(nóng)機推廣鑒定后已投入生產(chǎn),但從近兩年開展生產(chǎn)作業(yè)的情況看,存在抽凈率不高、對玉米植株有損傷、與地塊的大小不適應(yīng)性等諸多問題。今年,酒泉奧凱種機股份有限公司針對大型制種玉米去雄機適應(yīng)性差的問題,在甘肅省農(nóng)業(yè)農(nóng)村廳農(nóng)機化處的支持下,研發(fā)了適宜于河西走廊制種玉米主產(chǎn)區(qū)應(yīng)用的3CX-6A輕量化小型高地隙自走式制種玉米去雄機,目前,3CX-6A輕量化制種玉米去雄機已完成了樣機制作,進(jìn)入設(shè)備性能測試階段,從目前機具在張掖市甘州區(qū)黨寨鎮(zhèn)張家莊試驗驗證情況看,機具存在的問題一是由于制種玉米地塊大都沒有預(yù)留田間農(nóng)機行駛轉(zhuǎn)移道路,機具試驗驗證作業(yè)時地頭轉(zhuǎn)彎都有不便,輔助工藝時間長,影響了生產(chǎn)效率;二是作業(yè)試驗驗證時自動調(diào)節(jié)抽雄臂升降部分傳感器安裝位置表現(xiàn)出了不適應(yīng)操作的情況,需要進(jìn)一步優(yōu)化,且機具油缸屬于外協(xié)件質(zhì)量需要進(jìn)行改善。
三、措施與對策
一是進(jìn)一步加快制種玉米聯(lián)合收獲機械研制開發(fā)與推廣應(yīng)用步伐。針對玉米制種品種多樣、種植模式差異大的現(xiàn)狀,根據(jù)地域特點,依托酒泉奧凱種機股份有限公司“甘肅省農(nóng)作物種業(yè)裝備研發(fā)中心”,盡快研制開發(fā)出臥式割臺制種玉米聯(lián)合收獲機,結(jié)合主栽品種的性狀特征,優(yōu)化相關(guān)作業(yè)參數(shù)、機具結(jié)構(gòu)參數(shù)和整機性能參數(shù),提高機具的適應(yīng)性,改善作業(yè)效果,提高生產(chǎn)者對機械化作業(yè)機具的認(rèn)可度,促進(jìn)玉米制種全程機械化機具的推廣。
二是針對目前酒泉奧凱種機股份有限公司已經(jīng)研制開發(fā)出的3CX-6A輕量化小型高地隙自走式制種玉米去雄機,堅持優(yōu)化設(shè)計與田間試驗相結(jié)合,進(jìn)行較大規(guī)模的試驗考核,通過在生產(chǎn)一線實踐中取得的數(shù)據(jù)做出改進(jìn)和創(chuàng)新,提高機具的適用性、可靠性和經(jīng)濟(jì)性,加快產(chǎn)品商品化、市場化轉(zhuǎn)化力度,盡快投入大面積制種玉米抽雄作業(yè)。
三是開展全程機械化抓點示范。以抽雄、收獲等關(guān)鍵環(huán)節(jié)機械化生產(chǎn)為重點,學(xué)習(xí)借鑒農(nóng)業(yè)農(nóng)村部制種玉米全程機械化科研基地(河西學(xué)院),建設(shè)制種玉米研產(chǎn)推用四位一體全程機械化示范點,引進(jìn)不同型號的玉米聯(lián)合收獲機械,在不同品種的玉米制種生產(chǎn)基地,開展多層次、多地域的試驗示范,探索制種玉米全程機械化配套機具方案和技術(shù)路線,形成可復(fù)制、可推廣的技術(shù)模式,通過引機具、做試驗,推技術(shù),以點帶面,推進(jìn)制種玉米生產(chǎn)全程機械化。
四是強化良田良種良制良法良機融合。加強部門和行業(yè)間的協(xié)同合作,通過開展農(nóng)業(yè)技術(shù)革新和適宜于機械化作業(yè)種植模式研究,深化農(nóng)機農(nóng)藝融合,實現(xiàn)“帕累托最優(yōu)”,為實現(xiàn)制種玉米全程機械化創(chuàng)造條件,結(jié)合高標(biāo)準(zhǔn)農(nóng)田建設(shè)加強機耕道建設(shè),因地制宜明確田間道路、田塊長度寬度與平整度等宜機化要求,開展農(nóng)田宜機化改造,推動良種良法良田良機良制相配套,使制種玉米生產(chǎn)農(nóng)機裝備有用武之地。
