Resha niz chun digar uzvhoi rastani ba oksigeni havo ehtiyoji kalon dorad. Resha dar vaqti nafaskashi oksigeni havoro nafas girifta gazi karbonatro khorij mekunad. Inro bo tajribai oddi isbot kardan mumkin ast. Agar niholi mushungi (lubiyo yo nakhudi) dar arramayda sabzondashudaro girifta, arramaydahoyashro afshonda ba dokhili probirka guzorem 38 va pas az 35-40 daqiqa onhoro az on jo berun karda, chubaki dargironro ba on dokhil kunem, vay khomush meshavad.

Vale dar probirkai digari tamoman kholi chubaki dargiron shuda sukhtanashro davom medihad. In tajribaho isbot mekunand, ki Hamin tavr, hangomi parvarishi rastani ba on boyad diqqat dod, ki resha bo havoi toza muntazam tamin boshad. Baroi in khokro payvasta narm kardan lozim ast.dar probirkai tajribavi oksigen mavjud nest. Zero reshahoi mushung oksigeni havoro nafas kashidaand.

Az norasoii oksigen khususan rastanihoe, ki dar gilzamin va shibarzamin nashunamo dorand, zarar mebinand. Dar in guna zamin- ho ob havoro fishurda mebarorad va nafaskashii resha nomutadil megardad. Hususan, rastanihoe, ki dar shibarzamin va botloqzamin meruyand, sust inkishof meyoband.

Bo asbobhoi narmkunanda narm kardani zamin ahamiyati digar ham dorad. CHunin narmkuniho dar qitahoi zamin boisi nigoh doshtani nami megardad va bar zammi in safolaki zamin barham doda meshavad. Bo in tadbirho bukhor shudani ob az kabathoi chuqurtari khok qat megardad. Az in ru, narm kardani zaminro bazan “obyorii khushk” meguyand. YO in ki bo iborai digar: “Ba joi du bor bad ob mondan, yak bor nagzakak narm kardani zamin behtar ast”.

Hamin tavr, nashunamoi mutadil va hosilnokii rastaniho ba surati nafaskashii reshai rastaniho zich vobastagi dorad.

  1. CHi tavr isbot kardan mumkin ast, ki resha nafas mekashad?
  2. Baroi chi bekhi rastanihoro narm mekunand?
  3. Baroi chi dar shibarzamin va botloqzorho rastaniho sust mesabzand?
  4. Dar kadom holatho iborai “obyorii khushk”-ro istifoda mebarand?
  5. Dar ravandi nafaskashii resha kadom gaz nafas girifta meshavad va kadom gaz khorij meshavad?
