　　【農(nóng)機(jī)網(wǎng) 科技創(chuàng)新】 近日，加工所農(nóng)機(jī)所依托國家重點(diǎn)研發(fā)計劃子課題“高稈禾草收獲機(jī)切碎與拋送系統(tǒng)研究”專項(子課題編號: 2016YFD070170502)，成功研制了新型拋送式王草切碎收集機(jī)，在廣東海洋大學(xué)濱海農(nóng)業(yè)學(xué)院基地和湛江市麻章粵興種養(yǎng)專業(yè)合作社進(jìn)行了試驗(yàn)，廣東海洋大學(xué)濱海農(nóng)業(yè)學(xué)院專家和合作社經(jīng)理進(jìn)行了觀摩。
 
試驗(yàn)現(xiàn)場
 
　　目前王草機(jī)械化收割，一般是使用(玉米)秸稈聯(lián)合收獲機(jī)，但該機(jī)結(jié)構(gòu)復(fù)雜，價格較高，需要十幾萬元，一般規(guī)模較小的養(yǎng)殖戶買不起，無機(jī)可用。該類機(jī)械存在收割植株長勢不高、葉片又長又柔軟的王草時，葉片不容易切斷而纏繞堵塞機(jī)具，或遇到植株長勢特別茂盛，收割瞬間喂入量較大時，容易堵塞機(jī)具，不能正常作業(yè)，以及割茬高度不一致等問題。圍繞市場需求，根據(jù)王草分蘗能力強(qiáng)、生長不均的特點(diǎn)，及其叢生、倒伏生長的狀態(tài)，加工所農(nóng)機(jī)所開發(fā)了一種適合我國南方熱帶地區(qū)作業(yè)的王草收獲機(jī)具，該機(jī)集王草粉碎、回收功能于一體，徹底解決了堵塞機(jī)具的技術(shù)難題，純工作生產(chǎn)率約5.3畝/小時，收獲效率高；收獲后可直接或二次粉碎后飼喂，或做青貯飼料使用，效果較好；作業(yè)油耗低，約3kg/畝，約為現(xiàn)有相同工作幅寬收獲機(jī)械的一半；整機(jī)結(jié)構(gòu)簡單，制造容易，售價約為現(xiàn)有小型收獲機(jī)的一半，一般養(yǎng)殖戶買得起、用得起，滿足小規(guī)模養(yǎng)殖場對收獲機(jī)械產(chǎn)品的需求。該機(jī)收割菠蘿葉同樣效果比較好，收獲效率、作業(yè)質(zhì)量和油耗均比較理想。
 
作業(yè)及飼喂效果
 
　　本次試驗(yàn)得到了專家和業(yè)主的認(rèn)可，下一步將加強(qiáng)熱帶地區(qū)王草機(jī)械化收獲技術(shù)的推廣應(yīng)用，以滿足養(yǎng)殖戶對王草飼料的需求。
