植保無人機何以被貼上“綠色環(huán)保”的標簽？

　　【中國農(nóng)機網(wǎng) 本站原創(chuàng)】現(xiàn)今，農(nóng)用植保無人機進入繁榮時代，其、、綠色環(huán)保的特點被大眾所公認。但大多數(shù)人不知道，植保無人機為何被貼上綠色環(huán)保的標簽。

 
　　體型小巧，材質(zhì)輕
 
　　身材小巧也就意味著制作時耗用的材料少。目前我國大的植保無人機直徑5米，重136斤，而一臺普通的傳統(tǒng)農(nóng)用機械至少要達上千斤。
 
　　復(fù)合材料的使用，可以減輕機身重量。傳統(tǒng)的無人植保機原材料多采用鋁合金等金屬材料，隨著復(fù)合材料的推廣應(yīng)用，其比強度和比剛度高、熱膨脹系數(shù)小、抗疲勞能力和抗振能力強的特點深受廠家青睞。并且，和傳統(tǒng)金屬材料相比，將其應(yīng)用于無人機結(jié)構(gòu)中可以減重25%~30%，同時增加有效載荷、提高自身安全性。
 
　　強度高、質(zhì)量輕的碳纖維復(fù)合材料被廣泛應(yīng)用于無人機制造。碳纖維管材通過拉擠、纏繞或吹氣成型，很大程度上可以代替植保無人機的機身機構(gòu)和零部件中鋁合金管材的使用。并且，碳纖維管材的生產(chǎn)技術(shù)已經(jīng)很成熟，能夠通過不同的模具生產(chǎn)出各種型材，不僅可以根據(jù)個體需求定制不同的壁管形狀、長度、壁厚等，而且在后期加工過程中還可以選擇表面3K紋路或者噴漆等不同方式進行包裝和美化，與此同時，批量化的生產(chǎn)方式也能有效降低產(chǎn)品成本。
 
　　施肥，利用率高
 
　　2015年，我國化肥農(nóng)藥用量世界，但化肥、農(nóng)藥的利用率比發(fā)達國家低15%-20%，降低使用量、提高利用率勢在必行。2016年，我國著力打好農(nóng)業(yè)面源污染治理攻堅戰(zhàn)，深化推進綠色防控技術(shù)應(yīng)用，農(nóng)藥使用量繼續(xù)零增長，化肥使用量自改革開放以來也接近零增長。2017年農(nóng)業(yè)植保無人機的繁榮，更加帶動一批農(nóng)業(yè)的*通過植保無人機的噴灑來提高農(nóng)藥利用率、降低農(nóng)藥使用量。
 
　　農(nóng)民大多是一家一戶分散防治病蟲。農(nóng)藥用量不集中，不能合理充分被利用，且大多數(shù)農(nóng)民田間施藥未經(jīng)專門培訓(xùn)，不當(dāng)用藥、過量用藥現(xiàn)象嚴重，造成農(nóng)藥大量浪費。同時，傳統(tǒng)小型的噴霧器，作業(yè)效率低；大霧滴、大容量的噴灑，農(nóng)藥利用效率低。因此，農(nóng)業(yè)施肥迫切需要使用先進的藥械來提高農(nóng)藥利用率。
 
　　植保無人機易學(xué)易操作。操作人員一般經(jīng)過30天左右的訓(xùn)練即可掌握要領(lǐng)并執(zhí)行任務(wù)，并且只要站在地頭上通過遙控器操作，植保無人機便可在一小時內(nèi)完成上百畝的莊稼滅蟲工作。
 
　　植保無人機采用低量噴霧技術(shù)。在噴灑作業(yè)的過程中，藥液經(jīng)過無人機霧化部件的作用而分散，形成細小的霧滴顆粒，覆蓋度高、滲透性好，可以使藥劑發(fā)揮出佳效果，并且充分發(fā)揮粒徑大小所帶來的優(yōu)勢，從而達到防治病蟲草害的目的。
 
　　綠色環(huán)保，效率高
 
　　農(nóng)用植保無人機個頭小巧，其載重量可以達到5-20kg。一般10L藥箱的無人機，單次分型10分鐘，作業(yè)面積可達300畝左右，而人工施肥一畝田地大概要用30L配制好的農(nóng)藥。有數(shù)據(jù)統(tǒng)計，無人機噴灑效率是傳統(tǒng)人工的15-80倍，農(nóng)藥使用量、用水量分別比傳統(tǒng)人工至少節(jié)約50%和90%。
 
　　市場上的植保無人機有電動和油動兩種。電動自不必說，輕便、價低必屬綠色能源，但油動卻認為電機存在動力不足、續(xù)航短等缺點。雖然雙方都一直難以接受彼此，而爭吵不休，但是跟傳統(tǒng)的大型農(nóng)業(yè)機械相比，其電耗油耗都算得上是綠色環(huán)保了。舉個簡單的例子，田地里工作的播種機一啟動就會有黑煙排出，然而播種的無人機如果工作的時候冒煙，那就不能工作了。
 
　　以上只是農(nóng)用植保無人機的部分優(yōu)點，但是從這些優(yōu)點當(dāng)中已足以證明植保無人機行業(yè)前期可期，值得大力推廣使用。(本文由中國農(nóng)機網(wǎng)原創(chuàng)，轉(zhuǎn)載請注明出處，違者必究！)
