Cholimira cholimba kwambiri komanso cholimba

Kufotokozera Kwachidule:

【Pulawu Yothira Moyenera】Yopangidwa ndi chitsulo cha manganese champhamvu cha 65Mn, ndipo imatenthedwa ndi kutentha konse komanso kuzima kwa tsamba, kuuma kwa m'mphepete mwake kumafika pa HRC52-58, zomwe zimapangitsa kuti kukana kutha ndi katatu. Malo opindika a thupi la fosholo amapangidwa mwachilengedwe, kuonetsetsa kuti kuzama kwa kulima kuli kokhazikika kwa 18-25cm, kuchuluka kwa kusweka kwa nthaka kupitirira 90%, komanso kuchepa kwa 15% kwa kukana kugwira ntchito. Imagwirizana ndi mafelemu akuluakulu opachikidwa, okhala ndi mabowo okhazikika, oyenera kugwiritsidwa ntchito m'malo osiyanasiyana monga nthaka youma ndi dongo, zomwe zimapangitsa kuti ulimi ukhale wogwira mtima komanso wosunga mphamvu.

Chomera cholimira ndi gawo lofunika kwambiri pa ulimi wamakono, chomwe chimapangidwira kulima nthaka moyenera, kolimba, komanso kosalimba. Pogwiritsa ntchito zipangizo zamakono komanso mawonekedwe opangidwa mwaluso, chimadula mosavuta nthaka kuti chigwire ntchito yolima, kuswa nthaka, ndikuphimba udzu, ndikukonza malo abwino oti mubzalire. Ndi chisankho chabwino kwambiri chowongolera kugwiritsa ntchito bwino ulimi, kuchepetsa kugwiritsa ntchito mafuta, komanso kuchepetsa ndalama zogwirira ntchito kwa nthawi yayitali.

1、Zinthu: Zopangidwa ndi chitsulo chapamwamba cha boron kapena chitsulo chosungunuka, zomwe zimachizidwa ndi njira yapadera yotenthetsera (monga kuzimitsa ndi kutenthetsa) kuti zikhale zolimba kwambiri (HRC 48-55 kapena kupitirira apo) pamphepete mwapamwamba, pomwe thupi la fosholo limakhalabe lolimba komanso lolimba.

2、Ndondomeko: Mphepete mwachitsulocho imatha kuzimitsidwa pafupipafupi kapena kuwotcherera ndi ndodo zowotcherera/zingwe zolimba za aloyi, zomwe zimapangitsa kuti zikhale zotetezeka kawiri ndikuwonjezera moyo wa zigawo zomwe zimatha kusweka nthawi 2-3.
