Kushandiswa kwemuchina wakadzika wevhu kunogona kunyatso vandudza ivhu rekuchengetedza mvura, kubvuma zvizere kunaya kwechisikigo, uye kumisikidza madhamu evhu, ayo achaita basa rakakosha mukugadzirisa kunetsa kwezvimhingamipinyi zvekurima munzvimbo dzakaoma uye kusimudzira kusimukira kwekurima.
① Inogona kunyatso kutyora pasi pegejo rakaoma rakagadzirwa nekurima kana kubvisa mashanga kwenguva yakareba, zvinobudirira kuvandudza kupenya kwevhu uye kupinza kwemhepo, uye ivhu hukuru hukuru mushure mekunyorovesa kwakadzika i12-13g/cm3, inokodzera chirimwa. kukura nekusimukira uye zvinobatsira kudzika midzi yembesa.Kudzika kwemakanikasubsoilinginogona kusvika 35-50cm, izvo zvisingagoneke nedzimwe nzira dzekurima.
②Mechanical subsoilingKushanda kunogona kuvandudza zvakanyanya kugona kwevhu rekuchengetedza mvura nemvura yechando, uye kunogonawo kusimudza hunyoro hwevhu kubva pamusimboti wevhu mumwaka wakaoma, uye kuwedzera machengeterwo emvura epairimi.
③ Basa rekudzika-kusunungura rinongosunungura ivhu, haritendeuki ivhu, saka rinonyanya kukodzera nzvimbo yevhu dema isina kudzika uye haifanirwe kutenderedzwa.
④Kuenzaniswa nemamwe mashandiro,mechanical subsoilingine kushomeka kwakaderera, kushanda kwakanyanya uye kuderera kwekushandisa mari.Nekuda kwehunhu hwayo hwakasiyana hwezvimiro zvezvikamu zvekushanda, kuramba kushanda kwemuchina wepasi pasi zvakanyanya kuderera pane kuya kwekugovana kurima, uye chiyero chekudzikisa i1/3.Somugumisiro, kushanda kwekushanda kwakakwirira uye mari yekushanda inoderedzwa.
⑤ Mechanical kusunungura kwakadzika kunogona kuita kuti mvura nechando zvipinde mumvura, uye zvakachengetwa muvhu re 0-150cm, zvichiita dura guru revhu, kuitira kuti mvura yezhizha, chando chechando uye chitubu, kusanaya kwemvura, kuve nechokwadi chekunyorova kwevhu.Kazhinji, minda ine ivhu rakadzika kupfuura ivhu rakadzika inokwanisa kuchengeta 35-52mm mvura yakawanda muvhu re 0-100cm, uye avhareji yemvura yeivhu re 0-20cm inowedzerwa ne 2% -7% zvichienzaniswa ne Mamiriro ekurima echinyakare, ayo anogona kuona ivhu rakaoma pasina kusanaya kwemvura uye kuve nechokwadi chekumera kwekudyara.
⑥ Kusunungura kwakadzika hakutendeuki ivhu, kunogona kuchengetedza chifukidziro chezvinomera pamusoro, kudzivirira kukukurwa kwevhu uye kukukurwa kwevhu, kunobatsira kuchengetedza nharaunda yezvakatipoteredza, kuderedza jecha remunda uye guruva rinoyangarara rinokonzerwa nekuratidzwa kwevhu nekuda kwe kushandura nyika, uye kuderedza kusvibiswa kwezvakatipoteredza.
⑦Mechanized subsoilingrakanakira marudzi ese evhu, kunyanya kuminda ine goho riri pakati nepakati uye shoma.Avhareji yekuwedzera kwegoho rechibage inosvika 10-15%.Avhareji yekuwedzera kwegoho resoya bhinzi inenge 15-20%.Kuisa pasi pasi kunogona kuwedzera mwero wekushandiswa kwemvura yekudiridza neinosvika 30%.
