Ukubunjwa komhlaba

Ukuhlelwa Umhlaba kusekelwe kumgaqo ingqalelo umhlaba njenge uhlobo elizimeleyo ezikhethekileyo lomzimba, elo ngebande elinye kunye izimbiwa, izityalo kunye nezilwanyana. Le ndlela yokuhlelwa isekelwe phezu iimpawu imvelaphi le yemihlaba. Icandelo lokuqala umhlaba ngenxa yemfuza Dokuchaev

Uphawu engundoqo yazo ukwahlulwa - luhlobo lomhlaba. Le yunithi yokuhlela kuthetha imihlaba nazo phantsi kweemeko ezifanayo kunye neempawu ezifanayo kunye nesakhiwo.

Phakathi edume siya ukwahlula ezi ntlobo zilandelayo imihlaba: podzolic, krasnozems, umhlaba omnyama, umgxobhozo wetyuwa, kunye nabanye. Iintlobo zomhlaba zahlulwe zibe iintlobo zeHPV zingonobangela kwi kwisizukulwana iintlobo emaXhoseni kunye neendidi.

Iintlobo zeHPV zingonobangela zibonisa iimpawu ezikhethekileyo lenkangeleko yomhlaba. Lidlala indima njenge nemozulu elizwekazi neemeko thermal lommandla lesibanzi. Iintlobo zeHPV zingonobangela intermediates phakathi kweentlobo.

ukwahlukana Further kwenzeka kwisizukulwana kunye neentlobo zomhlaba. I-General uqhelekileyo zomhlaba: eqhelekileyo, obrak, intsalela-ezinetyuwa, saline, isanti zwi kunye gley umfowunelwa, carbonate eyintsalela, intsalela-ngokoma.

Lonke uhlobo umhlaba i ukwahlulwa eyongezelelweyo iintlobo. View bubonisa indlela ndilithethile inkqubo ukuyilwa lomhlaba, wayenza uhlobo oluthile lomhlaba. Ngenxa yoko, phakathi ezichongiweyo iqela esiXhoseni. Le enxulumene olunye uhlobo lomhlaba, umahluko apho ubume babo mechanical kuphela. Ezi ziquka udongwe novunduvundu, ezinentlabathi novunduvundu uyisanti. Isahlulo ezintlwini kuthetha ukuba umhlaba imbonakalo efanayo kunye nemvakalo, kodwa izinto umzali enemvelaphi ezahlukeneyo.

Iipropati ezahlukeneyo zixhomekeke ngqo koko yokwakheka komhlaba.

Eli xabiso ixhomekeke umlinganiselo kwamasuntswana ezahlukeneyo zomhlaba ertyisi kwaye sibonakaliswa njengepesenti. Intlala, iingqalutye kunye namatye babe permeability ihlwempu, ukwakha amaqhekeza amatye kunye nezinto zaseprayimari. Sand na impahla kudlula ngokukhawuleza ngamanzi, ekubeni phantse iqulathe kuphela yezimbiwa zaseprayimari. Uthuli iqulethe izimbiwa aphakamileyo, kukufukuka emanzini - le nto ibangela iimpawu zomhlaba ezifana stickiness kunye plasticity. Ukubunjwa bayalishiya eli elitshisiweyo iquka izimbiwa aphakamileyo ngodongwe. Bona kalanga kakhulu emanzini, ngoko musa ungaphoswa phantse kungekho manzi, akukho moya.

Ukuba amasuntswana kuyehla ubukhulu, le nkqubo iqala yemozulu kwaye ukuyilwa elandelayo yezimbiwa zamabanga - yinto hayidroksayidi yesinyithi, alumina, aluminosilicates kunye carbonates ka Ca, K, mg.

Ubungakanani izinto mechanical echaphazela ukwakhiwa kwawo iikhemikhali kunye neempawu zomzimba. Ngoko ke, ukwazi ubume bomhlaba, unako ukufumana oko iipropati kuyo anazo.

Engasentla lwexa zomhlaba kunye zomhlaba-ngokwakha amatye oko, kuxhomekeka kubume mechanical, yahlulwe:

• sandy:

- uhlobene;

- evakalala.

• Womile.
• nobumba:

- enzima;

- avareji;

- nemiphunga.

• obambe:

- enzima;

- avareji;

- nemiphunga.

texture ezahlukeneyo umhlaba, apho isiqulatho sodongwe ngokwasemzimbeni, kuchaphazela ipropati ezifana ductility. Xa izalathi ezahlukahlukeneyo, ilizwe ezinokuqengqeleka libe yibhola okanye intambo. Oku kunceda ukuba ukujonga ubunjani umhlaba entsimini. igama layo ngokuqhelekileyo ibonisa isakhiwo yayo mechanical. Ngokomzekelo, eyona umhlaba black obambe enzima.

Iipropati Agronomic imihlaba ixhomekeke texture lwabo. Easy ukuphatha novunduvundu oyisanti, kuba ibizwa ngokuba emiphungeni. Ngokwahlukileyo koko, obambe nodongwe bazakhele igama elihle esindayo ngenxa neenzima unyango agronomic. Noko ke, ukuba ibe ngaphezulu izondlo kunye nomgquba, ngokwahlukileyo ukuya obambe oyisanti oyisanti, yaye ngako oko zithathwe ochumileyo.
