　　【農(nóng)機(jī)網(wǎng) 科技創(chuàng)新】近日，農(nóng)機(jī)所甘蔗機(jī)械化團(tuán)隊(duì)與南亞所旱作新材料團(tuán)隊(duì)聯(lián)合研發(fā)的小型糞污沼液深施還田機(jī)在湛江市試驗(yàn)成功，并交付湛江正大集團(tuán)投入使用，服務(wù)湛江市正大集團(tuán)(遂溪)生豬產(chǎn)業(yè)園。
 
　　為了更好利用養(yǎng)殖場畜禽廢棄物糞污沼液，避免因直接排放而造成對農(nóng)田環(huán)境污染，研發(fā)團(tuán)隊(duì)歷經(jīng)1年多協(xié)作攻關(guān)，創(chuàng)新設(shè)計(jì)深施犁頭、快速掛接裝置、抽液系統(tǒng)、排液裝置和懸掛傳動(dòng)等關(guān)鍵部件，經(jīng)過多次的試驗(yàn)與優(yōu)化改進(jìn)，終于研制出了適應(yīng)南方小地塊作業(yè)的糞污沼液深施還田機(jī)，結(jié)合農(nóng)機(jī)信息化監(jiān)控系統(tǒng)，可遠(yuǎn)程實(shí)時(shí)監(jiān)控機(jī)具深松深度、還田作業(yè)面積等信息，實(shí)現(xiàn)還田信息化監(jiān)控作業(yè)。畜禽糞污經(jīng)長時(shí)間沉淀發(fā)酵處理后，經(jīng)過深埋還田，可以實(shí)現(xiàn)“安全還田、變糞為寶”且有效改良土壤。
 
　　該機(jī)集開溝犁地、糞污沼液還田、覆土于一體，犁地的同時(shí)進(jìn)行糞污沼液還田，達(dá)到糞污沼液深埋，且抽液快速，排液均勻還田，工效高。罐體容量可根據(jù)拖拉機(jī)動(dòng)力配套選取5m3、6m3、8m3等，形成了系列化，適應(yīng)配套100-210型輪式拖拉機(jī)，生產(chǎn)效率≥5畝/小時(shí)，施肥犁地深度≥30cm，整機(jī)長度短，轉(zhuǎn)彎靈活方便，適應(yīng)南方小地塊作業(yè)要求及作物對糞污沼液深施還田，既有效改良土壤。又深松犁地，合二為一，減少了還田作業(yè)成本。該機(jī)的研發(fā)成功，為畜禽糞污沼液安全高效利用提供了較好的利用方式，實(shí)施“糞肥還田、綠色種養(yǎng)循環(huán)”新模式，助力打通種養(yǎng)結(jié)合循環(huán)農(nóng)業(yè)“最后一公里”。
 
　　團(tuán)隊(duì)前期研發(fā)的大型糞便沼液深埋還田裝備已于2021年8月8日交付正大集團(tuán)交付投入使用。
