REJIMI NAMII KhOK

REJIMI NAMII KhOK bukhor shudan va baroi rastani sarf gardidani namii khok; majmui hodisahoest, ki harakat va gardishi obi qabathoi khokro nishon medihad. Rejimi namii khok omili muhimi paydoishi khok va hosilkhezii on ast. Rejimi namii khok  ba sharoiti obu havo, relefi mahal, rastaniho, khususiyathoi namii khok, chuqurii obhoi zerizamini va tariqi dehqoni vobasta ast. Dar surati mutadil budani nami dar khok prosesshoi mufid inkishof meyoband. va zamin hosilkhez megardad.. Sharoiti musoidi zamin ba sokht, tarkibi organikiyu mekhaniki, khususiyathoi fiziki va fizikiyu mekhanikii khok vobasta ast. Namii khok dar holathoi gunoguni fiziki bukhormonand, kapillyari, jozibavi va gayra meshavad.

Namii bukhormonand va jozibavi baroi rastani qarib befoida buda, obhoi kapillyariyu jozibaviro khok khub mejabbad va onho az in jihat manfiatnokand. Rejimi  namii khok yak chand nav ast.

Rejimi  namii khoki yakhbasta ba nohiyahoi shimoli khos buda, faqat tobiston yakhi sathi zamin kame ob meshavad. Khokash hamesha sernam.

Rejimi  namii khoki o b sh u y ba mintaqai tayga, ki khoki khokistarrangi chimdor va khokistarrangi botloqi dorad, khos ast. Az serborishi va kam bukhor shudani nami khoki viloyatu nohiyahoi mazkur doim sernam meboshad. Namii qabathoi boloii khok muttasil ba poyon zahida, ba obhoi zerizaminy hamroh meshavad.

Rejimi  namii khoki obshui mavsimi dar khoki mintaqahoi beshadasht, ki avvalhoi bahoru tobiston az barfu boron va obhoi ravoni girdu atrof nam megirad, joy dorad. Mohhoi garmu beborish namii qabati poyoni khok ba bolo baromada, bukhor megardad va ba obhoi zerizamini hamroh nameshavad.

Rejimi  namii khoki obshunashavanda ba nohiyahoi iqlimash khushki dasht va biyobon khos ast. Zamini in nohiyaho chandon nam nameshavad, zero borish kam buda, nami ba haddi ziyod bukhor megardad (namii khoki biyobonho 10—20 santimetr, zaminhoi bekorkhobida 1—2 metr, siyohkhok 2—4 metr). Dar davrai garmovu kamborish namii khok bukhor meshavad. Ob sathi zaminro shusta, ba qabathoi poyon nameravad va ba obhoi zerizamini hamroh nameshavad.

Rejimi  namii khoki  n a m k a sh ba khoke khos ast; khok na tanho az borishot, inchunin az obhoi zerizaminii na chandon chuqur niz nam mekashad. Dar sharoiti iqlimi khushk mushohida meshavad. Dar in mavrid obhoi zerizamini ba sathi zamin baromada, bukhor meshavand va aksar boisi paydoishi shurkhok megardand.

Rejimi namii irrigatsionii khok ba sharoiti zaminhoi obii nohiyahoi janub khos ast. Dar natijai obyorii chandinkarata khok to khudi qare, ki to on jo rastani resha davonida metavonad, nam meshavad. Bazan dar surati pesh omadani zarurati shusta partoftani namaki ziyodati khok to chuqurihoi az in ham beshtar nam meshavad.

Rejimi  namii khokro tavassuti yak qator tadbirhoi agrotekhnikiyu agromeliorativi idora mekunand.
