Cov evolution ntawm kev ua liaj ua teb sprayers tau nce los ntawm cov cuab yeej yooj yim phau ntawv mus rau complex, ntse cov cuab yeej. Thaum ntxov sprayers feem ntau yog ua los ntawm tooj liab, hlau, los yog fiberglass, cov ntaub ntawv uas tom qab tau hloov los ntawm sib dua, ruaj dua plastics. Cov ntsiab lus tseem ceeb hauv txoj kev loj hlob no suav nrog kev siv dav dav ntawm cov tshuaj tua kab mob, kev tsim kho tshiab hauv cov tshuaj tua kab mob, kev qhia txog kev siv thev naus laus zis thev naus laus zis, thiab lub sijhawm niaj hnub ntawm cov tshuab ntse uas sawv cev los ntawm cov nroj tsuag- kev tiv thaiv drones thiab cov neeg hlau ntse.
The Era of Manual Sprayers
Xyoo 1931, Zhejiang Provincial Institute for Plant Pest and Disease Control tau tsim Tuam Tshoj thawj lub teb chaws tsim tshuaj tsuag (ib - qauv raj)- tom qab ntawd hu ua "Universal Sprayer"- los ntawm kev ua qauv rau nws tom qab cov qauv los ntawm Tebchaws Meskas thiab Nyiv. Qian Haosheng, ib tug ntawm cov pioneers ntawm kuv lub teb chaws lub sprayer kev lag luam, yog lub npe hu ua "Leej Txiv ntawm Sprayers." Nyob rau hauv 1955, nws tsim ib lub teeb yuag orchard sprayer raws li cov kev xav tau tshwj xeeb ntawm orchards hauv Huangyan.
Nrov nrov thiab cov khoom siv tshiab ntawm Knapsack Sprayers
Kev tsim cov phau ntawv knapsack sprayers pib ntawm Shanghai Agricultural Machinery thiab Chemical Equipment Factory hauv 1959; los ntawm nruab nrab- xyoo 1960, tus qauv tsim tau tsim raws li "Gongnong-16" (Cov Neeg Ua Haujlwm-Peasant Model 16). Xyoo 1978, Quanzhou Sprayer Factory thiab Yunnan Agricultural Machinery thiab Chemical Equipment Factory pioneered siv polyethylene yas rau chemical tanks. Kev sim ua tiav ntawm knapsack sprayers tau ua tiav hauv xyoo 1982. Lub sijhawm xyoo 1980, cov tshuaj tsuag no tau pom sai sai; Nyob rau hauv 1983, ntau lawm ntau tshaj 7 lab units, accounting rau 60% ntawm tag nrho cov zis ntawm phau ntawv cog-tiv thaiv machinery rau xyoo ntawd.
Kev txhim kho ntawm Aerial Application Technology
Aerial daim ntawv thov technology tau tshwm sim nyob rau hauv thaum ntxov 20th caug xyoo. Xyoo 1918, Tebchaws Meskas tau ua thawj daim ntawv thov huab cua ntawm cov hmoov tshuaj tua kab, thiab xyoo 1922, Soviet Union tau tsim cov txheej txheem rau kev txau cov tshuaj tua kab los ntawm lub dav hlau. Tom qab Tsov Rog Ntiaj Teb Zaum II, kev siv tshuab siv dav hlau tau nthuav dav hauv ntau lub tebchaws muaj kev lag luam. Tuam Tshoj tau pib siv dav hlau rau kev siv tshuaj tua kab hauv xyoo 1951 thiab pib tsim cov dav hlau ua liaj ua teb- xws li Y-5 thiab Y-11 qauv-hauv xyoo 1957.
Era of Intelligence thiab Precision
kuv lub teb chaws cov nroj tsuag tiv thaiv drone kev lag luam tau pib xyoo 2008, thaum cov tuam txhab lag luam hauv tsev pib tsim cov roj av- muaj zog nyoob hoom qav taub rau kev tiv thaiv qoob loo. Xyoo 2016 yog suav tias yog "xyoo pib" rau kev txhim kho cov nroj tsuag tiv thaiv drones, cim kev lag luam nkag mus rau theem ntawm kev loj hlob sai [7]. Nyob rau hauv xyoo tas los no, kev txawj ntse thiab precision tau dhau los ua cov lus qhia tseem ceeb rau kev txhim kho.
