Mbali Zapamwamba Zapamwamba Zam'munda Wam'munda Wam'madzi a Spring
S-Tine Shank ndi chowonjezera cha makina a ulimi champhamvu kwambiri, chopangidwa ndi chitsulo chapamwamba kwambiri, cholimba komanso cholimba. Kapangidwe kake kapadera ka mawonekedwe a S kamatha kuletsa mphamvu ya kugunda, kusintha malo osafanana, kuchepetsa kumamatira kwa nthaka, ndikuwonjezera luso la ulimi. Ndi koyenera ntchito monga kulima, kumasula, ndi kupalira. Imagwirizana ndi mitundu yosiyanasiyana ya zowonjezerera mano a khasu ndipo ndi yosavuta kuyiyika. Pamwamba pake ndi polimba komanso sipadzadzidwa dzimbiri. Ndi chida chabwino kwambiri chosamalira nthaka m'minda ya zipatso, minda ya ndiwo zamasamba, ndi minda, zomwe zimathandiza ogwiritsa ntchito kupeza ntchito zaulimi zolondola komanso zogwira mtima.
Mu ntchito zaulimi zamakono, ubwino wa ulimi wa nthaka umakhudza mwachindunji kuchuluka kwa mbewu zomwe zimamera komanso zokolola zomaliza. Chowonjezera cha makina aulimi ichi—chokhala ndi masamba anayi olimbikitsidwa—chapangidwira makamaka ntchito za ulimi waulimi wamphamvu komanso wothandiza kwambiri ndipo ndi chowonjezera chabwino kwambiri cha ma rotary tillers, ma mini tillers, ndi ma thirakitala akuluakulu. Chogulitsachi chimaphatikiza njira zopangira zapamwamba komanso kapangidwe ka makina, cholinga chake ndi kupatsa ogwiritsa ntchito chidziwitso chapamwamba cha "ntchito imodzi, miyezo yambiri yokwaniritsidwa."
Chogulitsachi chili ndi kapangidwe kapadera ka masamba anayi, komwe kamapereka kugawa kwamphamvu kofanana poyerekeza ndi kapangidwe kachikhalidwe ka masamba awiri kapena atatu. Seti iliyonse ya masamba imakonzedwa mozungulira, ndikupanga malo odulira mosalekeza komanso olumikizana panthawi yogwira ntchito. Kapangidwe kameneka sikuti kamangochotsa "kulima kosaloledwa" panthawi yogwira ntchito komanso kumapangitsa kuti nthaka isweke bwino ndikusakanikirana kamodzi kokha. Kaya ndi malo olinganiza kapena kubwezeretsa malo otayirako, imatsimikizira nthaka yosweka bwino komanso yolinganiza, kukwaniritsa zofunikira zaulimi za "kumasuka pamwamba ndi kulimba pansi."
Kuti athane ndi malo ovuta a nthaka (monga dongo, mchenga wouma, komanso malo okhala ndi miyala yochepa), tsamba ili limagwiritsa ntchito chitsulo cha manganese cha 65Mn ngati maziko. Chipangizochi chili ndi mphamvu yolimba kwambiri komanso malire otanuka. Pambuyo pokonza kutentha kokhazikika, kuuma kwa tsamba pamwamba kumatha kufika 48-52 HRC, pomwe kumasunga kulimba kwamkati bwino, kuthetsa mavuto a masamba achikhalidwe omwe amatha kusweka ndi kusweka. Pamwamba pa tsambalo amachiritsidwa ndi utoto wotsutsana ndi dzimbiri, zomwe zimapangitsa kuti likhale losagwira dzimbiri, losatha kusweka, komanso lokhala ndi moyo wautali kuposa wa zinthu wamba.
Ubwino wa kapangidwe ka zigawo zinayi uli mu "kugwiritsa ntchito malo m'malo mwa mizere." Pakugwira ntchito kwenikweni, imatha kusintha mphamvu ya injini kukhala mphamvu yodulira. Chifukwa cha kulondola kwake kwakukulu kwa mphamvu, makinawo amagwira ntchito bwino popanda kugwedezeka kwambiri, zomwe sizimangochepetsa kugwiritsa ntchito mafuta kwa mathirakitala kapena ma mini-tiller komanso zimachepetsa kwambiri kutopa kwa ogwiritsa ntchito. Kukula kwake kogwirira ntchito kumawerengedwa bwino kuti kugwirizane bwino ndi mphamvu zomwe zimachokera ku mitundu yayikulu, kuonetsetsa kuti liwiro lokhazikika komanso kuchuluka kwa nthaka kusweka ngakhale nthaka itakhuthala.
