導(dǎo)讀：2021年4月2日以來，由農(nóng)機(jī)所國家木薯產(chǎn)業(yè)技術(shù)體系生產(chǎn)管理機(jī)械化團(tuán)隊研制的國內(nèi)首臺預(yù)切種式木薯種植機(jī)在廣西賀州市嘉時農(nóng)業(yè)發(fā)展有限公司木薯種植基地正式投入生產(chǎn)應(yīng)用。

　　【農(nóng)機(jī)網(wǎng) 科技創(chuàng)新】2021年4月2日以來，由農(nóng)機(jī)所國家木薯產(chǎn)業(yè)技術(shù)體系生產(chǎn)管理機(jī)械化團(tuán)隊研制的國內(nèi)首臺預(yù)切種式木薯種植機(jī)在廣西賀州市嘉時農(nóng)業(yè)發(fā)展有限公司木薯種植基地正式投入生產(chǎn)應(yīng)用。經(jīng)過一周的作業(yè)，累計完成了300余畝的種植作業(yè)，為公司搶回農(nóng)時創(chuàng)造了有利條件。
 
預(yù)切種式木薯種植機(jī)
 
　　短桿開杈木薯品種的機(jī)械化種植一直是木薯機(jī)械化的短板，由于該類木薯種桿過短，使用目前技術(shù)較成熟的實時切種式木薯種植機(jī)，在切種過程中存在切種連續(xù)性差、重播、種植效率低等問題，無法滿足生產(chǎn)要求。針對這一問題，研究團(tuán)隊2018年開始研發(fā)木薯預(yù)切種機(jī)械化種植技術(shù)，先由切種裝備將木薯種桿切斷為長度約15cm的木薯種莖，經(jīng)過對木薯種莖的篩選、消毒殺菌，再由預(yù)切種式木薯種植機(jī)實施寬窄雙行起壟種植。該種模式可保證短桿開杈木薯品種的種植質(zhì)量，提高種莖發(fā)芽率與成活率，便于實現(xiàn)種莖自動化排種和精量化種植，填補(bǔ)了短桿開杈木薯品種的機(jī)械化種植空白。
 
　　預(yù)切種式木薯種植機(jī)經(jīng)過2年多的持續(xù)優(yōu)化，在作業(yè)現(xiàn)場，公司管理團(tuán)隊與研究團(tuán)隊進(jìn)行了種植質(zhì)量聯(lián)合測定，生產(chǎn)率達(dá)4-6畝/小時，種植行距60-70cm，種植株距80-90cm，種植合格率達(dá)95%以上，滿足了實際生產(chǎn)的作業(yè)要求，各項技術(shù)指標(biāo)得到公司管理層的充分認(rèn)可。
