Masamba a makina a ulimi odulira ma disc, masamba odulira olemera, zowonjezera za makina olima, zosawonongeka komanso zolimba

Chogulitsachi ndi chowonjezera chofunikira kwambiri pa ntchito zaulimi zamakono, chomwe chimagwiritsidwa ntchito makamaka poswa nthaka pambuyo pa ulimi, kugawa nthaka, kupalira udzu, kusakaniza nthaka ndi feteleza, komanso kuphimba nthaka nthawi yokonzekera nthaka. Masamba athu odulira amapangidwa pogwiritsa ntchito chitsulo chapamwamba komanso ukadaulo wapamwamba. Kukana kwawo kuwonongeka ndi kugwedezeka, kuphatikiza ndi magwiridwe antchito okhazikika, kumawonjezera kwambiri magwiridwe antchito ndi ubwino wa ulimi, zomwe zimapangitsa kuti zikhale chisankho chabwino kwa alimi ndi mabungwe ogwirizana ndi ulimi omwe akugwiritsa ntchito njira zolima moyenera komanso zosamalira chilengedwe.

1、Ukadaulo: Pogwiritsa ntchito ukadaulo wapamwamba kwambiri wochizira kutentha (kuzimitsa + kutentha kwapakati), kuuma kwa m'mphepete mwa tsamba la harrow kumatha kufika HRC 42-48, pomwe kumasunga kulimba kwabwino kwa pakati, zomwe zimapangitsa kuti likhale lakuthwa komanso losawonongeka komanso losavuta kuswa. Nthawi yogwira ntchito imakulitsidwa ndi zoposa 30% poyerekeza ndi masamba wamba a harrow.

2. Pambuyo pa njira yapadera yochizira kutentha, mankhwalawa amakhala ndi kukana kutopa komanso kukana kugwedezeka pamene akusunga kuuma kwambiri. Amatha kuthana bwino ndi malo ovuta ogwirira ntchito m'munda (monga miyala ndi zipilala za nthaka zolimba) ndikupewa kusinthika kapena kusweka komwe kumachitika chifukwa cha kugunda.
