Ma rotary tillers athandizira kwambiri ulimi waku India.

A makina ozungulirandi zida zamakina zomwe zimagwiritsidwa ntchito polima.Imatha kulima, kulima ndi ntchito zina pansi.Mbiri yarototillerskuyambira m’zaka za m’ma 1800, pamene anthu anayamba kuyesa kugwiritsa ntchito mphamvu za nthunzi kapena mathirakitala kuti alowe m’malo mwa ulimi wamba.

M’zaka za m’ma 1840, katswiri wina wa ku America, dzina lake John Deere, anapanga makina opangira ma rotary tiller oyambirira, omwe anathandiza kwambiri luso la ulimi.Pambuyo pake, pamene mulingo wa makina a ulimi unkapitirizira kuyenda bwino, ma rotary tiller anapangidwanso ndi kutchuka, ndipo anayamba kugwiritsidwa ntchito padziko lonse lapansi.

Pamene teknoloji ikupita patsogolo, zamakonorototillerszakhala zogwira mtima kwambiri, zotsogola, komanso zokomera dothi ndi mbewu zosiyanasiyana.Zakhala chida chofunikira komanso chofunikira pakupanga ulimi, kupatsa alimi njira zolimira bwino komanso kuthandiza kukulitsa zokolola ndi zabwino zazaulimi.

A makina ozungulirandi chida chaulimi chomwe chimagwiritsidwa ntchito kulima ndi kumasula nthaka kuti ikhale yosavuta kulima mbewu.Imalowa mkati mwanthaka ndikutembenuza zigawo za nthaka potembenuza masamba kapena ma reki kuti amasule ndi kukonza nthaka, zomwe zimapangitsa kuti pakhale malo abwino odzala ndi kubzala mbewu.Zolima zozungulira zimatha kusintha mpweya wabwino wa nthaka ndi ngalande, kuthandizira kupalira komanso kukonza nthaka.Kugwiritsiridwa ntchito kwa ma rotary tillers kungachepetse mphamvu ya ntchito yolima pamanja komanso kupititsa patsogolo ulimi.

Monga ndikudziwira, mayiko ena omwe amagwiritsa ntchitorototillersambiri akuphatikizapo China, India, Brazil, United States, ndi Russia.Mayikowa ali ndi malo akuluakulu olimapo komanso kubzala kwaulimi, choncho pakufunika kwambiri kuti kulima mbewu kukhale koyenera komanso kuti nthaka ikhale yabwino.Komabe, mayiko omwe amagwiritsa ntchito ma rototillers kwambiri amatha kusiyanasiyana malinga ndi nthawi komanso malo.

Ku India, ma rotary tillers athandiza kwambiri paulimi.Amathandiza alimi kulima ndi kutembenuza nthaka moyenera, kupangitsa kufesa ndi kubzala bwino.Pochepetsa ntchito za anthu ndikuchepetsa ntchito zakuthupi kwa alimi;makina ozungulirakuthandizira kukulitsa zokolola zaulimi komanso kuchepetsa ndalama zopangira.Kuonjezera apo,rototillerszimathandiza kukonza mpweya wabwino wa nthaka komanso kuteteza nthaka kuti ikhale yabwino, motero imakhudza kakulidwe ka mbewu ndi zokolola.Chifukwa chake,makina ozunguliraamathandizira kwambiri pazaulimi waku India ndipo athandizira kwambiri pakukulitsa ulimi waulimi komanso moyo wa alimi.
