Gawo lothandizira kutentha losagwira ntchito

Kufotokozera Kwachidule:

Chowonjezera cha makina aulimi, pulawo, ndi gawo lofunika kwambiri pa pulawo la moldboard, lomwe nthawi zambiri limapangidwa ndi chitsulo chapamwamba cha boron kapena chitsulo cha spring. Kudzera mu njira zotenthetsera kutentha, limapeza m'mphepete mwake wakuthwa komanso wolimba kwambiri, limapereka mphamvu zabwino zolowera ndi kudula nthaka komanso kukana kuwonongeka. Malo opindika opangidwa mwasayansi amapukutira ndikuphwanya nthaka bwino pamene akuphimba zotsalira za mbewu. Amagwiritsidwa ntchito makamaka paulimi wa m'malo ouma, amachepetsa kukana kukoka ndipo ndi oyenera mitundu yosiyanasiyana ya nthaka kuphatikizapo mchenga ndi dongo.

Fosholo ya pulawo, monga gawo lofunikira kwambiri pa pulawo, ndiyo "chothyola nthaka" cholunjika kwambiri pakulima. Imayikidwa patsogolo pa thupi la pulawo, yomwe imayang'anira kudula nthaka molunjika, kudula mizu ya mbewu ndi zotsalira za udzu, kukhazikitsa maziko a ntchito zobwerezabwereza za nthaka, kuphwanya nthaka, ndi kuphimba. Mapulawo athu angapo apangidwa makamaka kuti agwiritsidwe ntchito pa ulimi wamakono wamphamvu komanso wothandiza kwambiri, ndipo ndi zinthu zofunika kwambiri kuti zitsimikizire kuzama kwa ulimi komanso kuchepetsa kukana kugwira ntchito.

Kulimba kwambiri: Pambuyo pa njira yapadera yochizira kutentha (kuzima mafuta + kutentha pang'ono), kulimba kwa tsamba la pulawo kumafika pa HRC 48-52, komwe kumakhala kolimba kwambiri ndipo kumatha kukana kuwonongeka kwa tinthu ta mchenga wa quartz m'nthaka.

Kapangidwe ka tsamba lodzinola lokha: Pa nthawi yogwira ntchito, tsamba la fosholo limakhala lakuthwa, zomwe zimachepetsa kukana kulowa m'nthaka. Poyerekeza ndi mapulawo wamba, limatha kuchepetsa kugwiritsa ntchito mafuta ndi pafupifupi 5% -10%.

Kugwira bwino ntchito yolowera m'nthaka: Kapangidwe kabwino ka ngodya yolowera m'nthaka ndi nsonga ya fosholo kamatsimikizira kuti pulawo ndi fosholo zimatha kufika mofulumira kuzama koyambirira kwa kulima ndikugwira ntchito bwino pansi pa nthaka zosiyanasiyana.

Kulima nthaka mozama: Kulumikizana bwino kwa nthaka kumathandiza kuti nthaka ikule bwino, kubisa bwino zotsalira za nthaka ndi feteleza, komanso kuwonjezera kuchuluka kwa zinthu zachilengedwe m'nthaka.

Mawonekedwe ofanana: opangidwa mosamala motsatira miyezo ya dziko (kapena miyezo ya ISO yapadziko lonse), yokhala ndi malo ambiri, imatha kusintha malinga ndi mitundu yambiri ya ma flip plaw opachikidwa ndi kukokedwa pamsika, ndipo ndi osavuta kuyika.

Imagwiritsidwa ntchito kwambiri pakulima minda youma, kuchotsa ziputu za minda ya mpunga, ndi ntchito zokonzanso nthaka. Kaya ndi nthaka yofewa yolima masika kapena nthaka yolimba yolima nthawi yophukira, pulawu iyi ingapereke ntchito yokhazikika komanso yodalirika.
