當前,正處于春耕春播的關鍵時期。為進一步提高春耕春播生產(chǎn)機械化水平和機械化技術到位率,保證機械化播種質量,助力糧油生產(chǎn)大面積單產(chǎn)提升,寧夏農(nóng)業(yè)機械化技術推廣站提出了全區(qū)春小麥機械化播種技術指引,加強技術指導與服務。
一、耕整地
在上茬作物收獲后,有條件的地區(qū)撒施基肥,實行冬翻田作業(yè),翻耕深度20 cm~30 cm。播前土壤整地宜早不宜遲,推薦采用高性能
聯(lián)合整地機,一次性完成滅茬、旋耕、鎮(zhèn)壓等多項作業(yè)。也可采用旋耕、耙耱、鎮(zhèn)壓分環(huán)節(jié)作業(yè),整地深度≥5 cm。作業(yè)后,地塊應平整,深度一致,地表高低落差≤3 cm,無雜草根茬,墑情良好。
二、播種
(一)品種與肥料選擇。根據(jù)農(nóng)藝推薦,選用經(jīng)國家和自治區(qū)審定的優(yōu)質高產(chǎn)、抗逆性強、適應性廣、宜機收的優(yōu)良品種。結合當?shù)夭∠x害發(fā)生情況,根據(jù)農(nóng)藝要求,進行拌種或包衣處理。肥料應為合格產(chǎn)品,流動性好,適用于機械作業(yè)。
(二)機具選擇。目前適應小麥播種的機型較多,多用12行~14行
條播機,推薦采用復式多功能、排種排肥智能化監(jiān)測等高性能
播種機,配備北斗輔助導航駕駛系統(tǒng),以提升播種質量。
(三)機具檢查。播種開始前應對照產(chǎn)品使用說明書全面檢查與保養(yǎng)播種機,檢查緊固部位是否緊固牢靠,各傳動部位是否轉動靈活。安全防護裝置是否齊全,安裝是否牢固可靠。查看并清除種肥箱內(nèi)的雜物和殘留的種子、肥料,清除開溝器和傳動機構上的雜草和雜物,調整鏈傳動裝置,確保機具保持良好的工作狀況。
(四)機具掛接。小麥播種機一般通過三點懸掛與拖拉機掛接。掛接后,調整拖拉機中央拉桿和左右提升桿位置,使播種機機架在縱向與橫向都處于水平狀態(tài),然后調整拖拉機左右限位螺桿(或限位鏈),使播種機橫向中心線與拖拉機縱向中心線相重合。在播種作業(yè)時,調整拉桿,使播種機工作時達到整體仿形的效果。拖拉機懸掛播種機后有翹頭現(xiàn)象時,需在拖拉機前加配重塊,以增加拖拉機的縱向穩(wěn)定性。
(五)機具技術參數(shù)調整。正式播種作業(yè)前應根據(jù)播種機的使用說明書和當?shù)胤N植農(nóng)藝要求,調整播種機的行距、播種量、施肥量、播種深度和施肥深度、作業(yè)速度等技術參數(shù),并進行試播。播種深度3 cm~5 cm,行距12.5 cm~15 cm,種肥距離5 cm~10 cm,畝播量20 kg~22.5 kg。對土壤墑情差或無灌溉條件的地塊,適當深播或深覆土,加重鎮(zhèn)壓。
(六)作業(yè)質量要求。種子在播行內(nèi)均勻分布,無斷條、漏播現(xiàn)象,各項作業(yè)指標符合相關作業(yè)質量要求。其中播種均勻性變異系數(shù)應≤35%,種子破損率應≤1.5%(金屬材料排種器)或≤0.5%(非金屬材料排種器),播種深度合格率應≥85%,種肥間距合格率應≥90%。
(七)播期。根據(jù)氣溫、土壤墑情等因素確定小麥適播期,適時頂凌播種。其中,引黃灌區(qū)適播期在2月下旬~3月中上旬,中部干旱帶適播期在2月下旬~3月中下旬,寧南山區(qū)適播期在3月中旬~3月底。
三、注意事項
拖拉機駕駛人員應經(jīng)過技術培訓,掌握機械化作業(yè)操作要領及當?shù)胤N植農(nóng)藝要求等方面的知識,掌握播種機械的正確使用、維護保養(yǎng)和作業(yè)質量指標知識。作業(yè)中,要嚴格按照農(nóng)機安全操作規(guī)程及播種作業(yè)安全注意事項進行操作,確保安全生產(chǎn)。播種機上嚴禁站人,不允許急轉彎和倒車,應盡量避免停車,必須停車時為防止出現(xiàn)缺苗“斷條”現(xiàn)象,應將播種機升起,后退一定距離,再繼續(xù)播種。開溝器入土后播種機不得后退,以免堵塞或損壞開溝器。地頭轉彎時應將播種機懸起或把開溝器及土壤工作部件升起,切斷排種器和排肥器的動力,升起劃行器,然后才能轉彎。
