Kugwiritsa ntchito makina odetsa kwambiri kumatha kupititsa patsogolo mphamvu yosungira madzi m'nthaka, kuvomereza mvula yachilengedwe, ndikukhazikitsa malo osungira nthaka, omwe angathandize kwambiri kuthetsa vuto la zovuta zaulimi m'madera ouma ndikulimbikitsa chitukuko cha ulimi.
① Imatha kuthyola pulawo yolimba yomwe imapangidwa ndi kulima kapena kuchotsa ziputu kwa nthawi yayitali, imathandizira kuti nthaka isapitirire komanso kutulutsa mpweya, komanso kachulukidwe kanthaka pambuyo pofewetsa kwambiri ndi 12-13g/cm3, yomwe ili yoyenera kubzala. kukula ndi chitukuko ndi kulimbikitsa mizu yakuya ya mbewu.Kuzama kwa makinasubsoilingimatha kufika 35-50cm, zomwe sizingatheke ndi njira zina zaulimi.
②Kuwonongeka kwamakinaKugwira ntchito kungathe kupititsa patsogolo mphamvu yosungiramo nthaka ya madzi amvula ndi chipale chofewa, komanso kungathe kukweza chinyontho cha nthaka kuchokera pakatikati pa nthaka m'nyengo yachilimwe, ndi kuonjezera kusunga madzi olimapo.
③ Ntchito yomatula mozama imangomasula nthaka, siitembenuza nthaka, motero ndiyoyenera kwambiri pagawo la dothi lakuda lakuda ndipo siliyenera kutembenuzika.
④Poyerekeza ndi ntchito zina,makina subsoilingali ndi mphamvu zochepa, zogwira ntchito kwambiri komanso zotsika mtengo.Chifukwa cha mawonekedwe ake apadera a magawo ogwirira ntchito, kukana kwa makina a subsoiling ndikocheperako poyerekeza ndi kulima kwa magawo, ndipo kuchepetsa ndi 1/3.Zotsatira zake, magwiridwe antchito amakhala apamwamba ndipo ndalama zogwirira ntchito zimachepetsedwa.
⑤ Kusungunula kwamakina kumatha kulowetsa madzi amvula ndi chipale chofewa, ndikusungidwa m'nthaka ya 0-150cm, kupanga dothi lalikulu, kotero kuti mvula yachilimwe, chipale chofewa ndi masika, chilala, kuonetsetsa kuti dothi lili ndi chinyezi.Nthawi zambiri, minda yokhala ndi dothi lozama kwambiri imatha kusunga madzi ochulukirapo 35-52mm munthaka ya 0-100cm, ndipo madzi apakati pa 0-20cm nthawi zambiri amawonjezeka ndi 2% -7% chikhalidwe chaulimi, chomwe chingathe kuzindikira malo owuma popanda chilala ndikuwonetsetsa kuti kubzala kumera.
⑥ Kumasula kwambiri sikutembenuza nthaka, kutha kusunga zomera pamwamba pake, kupewa kukokoloka kwa nthaka ndi kukokoloka kwa nthaka, kumathandiza kuteteza chilengedwe, kuchepetsa mchenga wa kumunda ndi fumbi loyandama chifukwa cha kukhudzana ndi nthaka chifukwa cha kutembenuza nthaka, ndi kuchepetsa kuipitsidwa kwa chilengedwe.
⑦Kuyika pansi pamakinandi yoyenera ku dothi la mitundu yonse, makamaka minda yokolola yapakatikati ndi yochepa.Kuchuluka kwa zokolola za chimanga ndi pafupifupi 10-15%.Kuchuluka kwa zokolola za soya ndi pafupifupi 15-20%.Kuthirira pansi kumatha kukulitsa kuchuluka kwa kagwiritsidwe ntchito ka madzi amthirira ndi 30%.
