Kugwiritsa ntchito rotary tiller makina olimba pafupipafupi zochizira kutentha

Mlimi wozungulira ndiye chigawo chachikulu cha mlimi wozungulira. Ikapita patsogolo ndi thalakitala, tsinde la mpeni lopingasa limazungulira, ndipo alimi angapo ozungulira omwe amaikidwa pamtengo wa mpeni amalima mosalekeza pamunda uku akugubuduza kutsogolo, kuswa zitunda ndi kudula zotsalira. Chiputu ndi kutaya nthaka mmbuyo. Amagwiritsidwa ntchito kwambiri mu mpunga, kulima masamba ndi ma greenhouses apulasitiki. Rotary tiller imatha kupangidwa mosiyanasiyana. Pakamwa pamakhala mchenga ndi miyala m’nthaka, ndipo chogwirira ndi tsamba zimapindika kapena kuthyoledwa ndi kukhudzidwa kwa miyala ndi mizu yamitengo m’nthaka, motero njira zolephereka zimavalidwa, kupindika ndi kusweka. Chifukwa chake, pamafunika kuti chodulira chozungulira pamakina owumitsa pafupipafupi chimakhala ndi kuuma kwakukulu komanso kukana kuvala, ndipo nthawi yomweyo chimakhala ndi mphamvu komanso kulimba. Kawirikawiri amapangidwa ndi 65Mn, T9 zitsulo, ndi zina zotero, kuuma pambuyo pa chithandizo cha kutentha ndi 48-54HRC, ndi chogwirira ndi 38-45HRC. Padi padi ndi zida zofunikanso, zomwe zimagwiritsidwa ntchito makamaka kulima m’minda yakumwera.
