Nsonga ya pulawo yachitsulo chosatha kutha, nsonga ya tsamba la pulawo losinthika, zida zamakina a zaulimi. Chithunzi Chowonetsedwa

Nsonga ya pulawo yachitsulo chosatha kutha, nsonga ya tsamba lotha kusinthika, zida zamakina a ulimi.

Kufotokozera Kwachidule:

Nsonga ya pulawo yokhala ndi mitu iwiri imapangidwa ndi chitsulo chapamwamba kwambiri chosatha, chokhala ndi kapangidwe kofanana mbali zonse ziwiri. Ikhoza kutembenuzidwa kuti ipitirire kugwiritsidwa ntchito mbali imodzi ikatha, zomwe zimapangitsa kuti ikhale ndi moyo wautali. Yopangidwira makamaka ma mini-tillers ndi zida zawo, imapereka ngodya zolondola zolowera m'nthaka komanso kukana kudula kwambiri. Yoyenera kutayira m'mitsinje, kulima mozama, komanso kumasula nthaka, imawongolera kwambiri kusweka kwa nthaka ndipo ndi gawo labwino kwambiri lolowa m'malo kuti liwonjezere kukana kwa kuwonongeka ndi kugwira ntchito bwino kwa zida zaulimi.

Mu ulimi wamakono, ubwino wa kukonzekera nthaka umatsimikizira mwachindunji maziko a kukula kwa mbewu. Pofuna kuthana ndi izi, tayambitsa pulawo lopangidwa mwaluso kwambiri. Kudzera mu kukonza kapangidwe kake kwapadera komanso kugwiritsa ntchito zipangizo zolimba kwambiri, cholinga chake ndi kuthetsa mavuto a pulawo lachikhalidwe, monga magwiridwe antchito ochepa, kuwonongeka mwachangu, komanso kusintha zida zosinthira pafupipafupi, kupatsa ogwiritsa ntchito mwayi wokonzekera nthaka motsika mtengo.

Chofunika kwambiri pa chinthuchi ndi kapangidwe kake ka mitu iwiri. Mbali imodzi ndi mbali yakuthwa yolowera m'nthaka yokhala ndi mawonekedwe osavuta, osinthika, zomwe zimapangitsa kuti nthaka yolimba ikhale yolimba komanso yophwanyika mosavuta, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito koyamba monga kulima mozama ndi kulima mozama. Mbali inayo ndi mbali yayikulu, yosatha, yomwe imakulitsa malo olumikizirana ndi nthaka ndikupereka kukhazikika kwabwino kwa mbali, koyenera ntchito zina monga kulima mozama, kuswa nthaka, ndi kugwetsa mipanda ndi kudula ming'alu. Ogwiritsa ntchito safunika kusintha mutu wonse wa pulawo; amatha kungosintha njira yoyikira kuti asinthe momasuka pakati pa njira ziwiri zogwirira ntchito, zomwe zimapangitsa kuti chowonjezeracho chikhale chogwira ntchito bwino komanso chogwira ntchito bwino.

Pofuna kuthana ndi mavuto ogwirira ntchito m'nthaka zaulimi zomwe zimakhala ndi mchenga wambiri komanso kuwonongeka mwachangu, timasankha chitsulo cha manganese chapamwamba kapena chitsulo chapamwamba cha 65Mn ngati maziko. Kudzera mu njira yotenthetsera yokha komanso kuzima mafuta, kuuma kwa pamwamba pa nsonga ya pulawo kumafika pa 48-52 HRC, pomwe pakati pake pamakhala kulimba kwambiri. Khalidwe la "kulimba kunja, kolimba mkati" limalola kuti lipewe kuwonongeka kwakukulu likakumana ndi zinthu zolimba monga miyala ndi mizu ya mitengo, zomwe zimathandiza kuti zisasweke kapena kusweka. Poyerekeza ndi nsonga wamba za pulawo za mutu umodzi, nthawi yake yonse yogwirira ntchito imaposa kawiri, kuchepetsa nthawi yopuma yosinthira m'munda.

Kaya ndi ntchito zolima kwambiri m'mafamu akuluakulu zomwe zimafuna kuthyola poto, kapena kusamalira minda ya zipatso ndi malo obiriwira zomwe zimafuna ulimi wokonzedwa bwino, nsonga ya pulawo yokhala ndi mitu iwiri ingathandize ogwiritsa ntchito kuchepetsa ndalama zogulira zida zosinthira ndi zoposa 30% chifukwa cha "njira imodzi, kugwiritsa ntchito kawiri". Nthawi yomweyo, imachepetsa nthawi yogwira ntchito chifukwa chosintha zida, zomwe zimapangitsa kuti ikhale chisankho choyenera chofananira ndi ntchito zamakina aulimi zomwe zimafuna kugwiritsa ntchito bwino kwambiri, kugwiritsa ntchito pang'ono, komanso kugwiritsa ntchito mwanzeru.
