Ukusetshenziswa komshini wokungcolisa ojulile kungathuthukisa ngempumelelo umthamo wokugcina amanzi enhlabathini, kwamukele ngokugcwele imvula yemvelo, futhi kusungulwe amadamu enhlabathi, azodlala indima ebalulekile ekuxazululeni ingqinamba yezinkinga zezolimo ezifundeni ezomile kanye nokukhuthaza ukuthuthukiswa kokukhiqizwa kwezolimo.
① Ingakwazi ukuphula igeja eliqinile eliphansi elakhiwe ngokulima noma ngokususa izinhlanga isikhathi eside, ithuthukise ngempumelelo ukungena kwenhlabathi nokungena komoya, futhi ukuminyana kwenqwaba yenhlabathi ngemva kokuthambisa okujulile kungu-12-13g/cm3, elungele ukutshala. ukukhula nokuthuthuka futhi kunomthelela ezimpandeni ezijulile zezitshalo.Ukujula komshiniukuzithobaingafinyelela ku-35-50cm, okuyinto engenakwenzeka ngezinye izindlela zokulima.
②I-subsoiling yemishiniukusebenza kungathuthukisa kakhulu umthamo wokugcinwa kwenhlabathi kwamanzi emvula namanzi eqhwa, futhi kungakhuphula umswakama wenhlabathi ongqimbeni lomhlabathi owumgogodla ngenkathi eyomile, futhi kwandise ukugcinwa kwamanzi ongqimba lokulima.
③ Umsebenzi wokuxegisa ujule uxegisa umhlabathi kuphela, ungaphenduki umhlabathi, ngakho-ke ufaneleka ngokukhethekile ungqimba lomhlabathi omnyama ongashoni futhi akufanele uphendulwe.
④Uma kuqhathaniswa neminye imisebenzi,ukufakwa phansi kwemishiniinokumelana okuphansi, ukusebenza kahle okuphezulu kanye nezindleko eziphansi zokusebenza.Ngenxa yezici zayo eziyingqayizivele zesakhiwo sezingxenye zokusebenza, ukumelana nokusebenza komshini ongaphansi komhlaba kuncane kakhulu kunokulima kwesabelo, futhi izinga lokunciphisa lingu-1/3.Ngenxa yalokho, ukusebenza kahle komsebenzi kuphezulu futhi izindleko zokusebenza ziyancipha.
⑤ Ukuxega okujulile ngomshini kungenza imvula neqhwa kungene amanzi, futhi kugcinwe kungqimba lomhlabathi ongu-0-150cm, kwakhiwe inhlabathi enkulu yokugcina amanzi, ukuze imvula yasehlobo, iqhwa lasebusika nentwasahlobo, isomiso, ukuqinisekisa umswakama womhlaba.Ngokuvamile, iziza ezinomhlabathi ojulile kakhulu kunenhlabathi ejulile zingagcina amanzi angu-35-52mm ngaphezulu ungqimba lomhlabathi ongu-0-100cm, kanti isilinganiso samanzi senhlabathi engu-0-20cm ngokuvamile senyuka ngo-2% -7% uma kuqhathaniswa ne izimo zokulima zendabuko, ezikwazi ukubona umhlabathi owomile ngaphandle kwesomiso futhi ziqinisekise izinga lokuvela kokuhlwanyela.
⑥ Ukuxega okujulile akuwuguquli umhlabathi, kungagcina ukumboza kwezitshalo okungaphezulu, kuvimbele ukuguguleka kwenhlabathi nokuguguleka kwenhlabathi, kusiza ekuvikelweni kwendawo ezungezile, kunciphisa isihlabathi sensimu kanye nesimo sezulu sothuli esintantayo esibangelwa ukuchayeka kwenhlabathi ngenxa ukushintsha umhlaba, nokunciphisa ukungcoliswa kwemvelo.
⑦Ukufakwa ngaphansi kwemishiniilungele zonke izinhlobo zenhlabathi, ikakhulukazi emasimini anesivuno esimaphakathi nesiphansi.Isilinganiso sokwanda kwesivuno sommbila silinganiselwa ku-10-15%.Isilinganiso sokukhula kwesivuno sikabhontshisi wesoya singaba ngu-15-20%.Ukufakwa ngaphansi komhlaba kungakhuphula izinga lokusebenzisa amanzi okunisela okungenani ngama-30%.
