Columnar apula izinhlobo ezithakazelisayo for balimi

Columnar apula izinhlobo njalo kwavusa isithakazelo phakathi abatshali, ngubani bakhangwa umqhele encane izihlahla. isiqu sabo esisemqoka, igcwele kopetsom bawe ngokoqobo egcwele izithelo. Lezi zihlahla apula akudingeki izihlahla, ngoba sibe namagatsha ambalwa. Kanye lezi zitshalo abe iqoqo izakhiwo ezithakazelisayo: bona akhiwa lenqwaba othela izithelo ohlangothini amagatsha ufushanisiwe esukela isiqu esiyinhloko ye-engeli kwesokudla. Ngenxa yalokho, columnar apula izinhlobo umumo icwecwe kakhulu pyramidal-tapered evumela ukusetshenziswa kahle isikhala engadini, uzigcinele zokutshala izihlahla ezithela eliphezulu.

Okokuqala columnar apula izinhlobo abangu ezifuywa eCanada phakathi nekhulu leminyaka eledlule. ukubukeka kwakhe, babophekile ithuba: izinhlobo endala mac isihlahla ngakhula ngokuphazima kweso legatsha okwenyanga Okumangazayo. Umtshali amehlo induku yokuqondisa, esingeyena amagatsha side, obukhulu kakhulu, futhi zibheka ezikhulayo ngokoqobo ugcwele njengoba lezimbali, izithelo. Ngemva kwakhe kwaba kuwo isiphunzi, kwaba sobala ukuthi ngokwanele kuguquka esitebeleni enomqhele ukuma mpo. Lokhu ezihlukahlukene yabizwa ngokuthi "vazhak". Yaqala ukuyisebenzisa kamuva Ukukhetha.

ERussia columnar apula izinhlobo okuqala ayengelona ngo-1972. I ezahlukeneyo engcono yatshalwa kuyo e Moscow, orel, Murmansk. ezintathu zalesi sihlahla ethathwe Ukukhetha: A eyingqabavu, yemifino kanye lulwimi into encane, Uthole udumo phakathi balimi nge iziza engadini nge isikhala elinganiselwe.

Nokho, ukuthola isivuno esihle kungenzeka kuphela uma uma lesi sitshalo unikezwe konke adingekayo ukuze ikhule evamile nokuthuthuka.

Izithombo abatshalwé ilandelana kude komunye nomunye ku ngamasentimitha amane. Ukutshala emgodini kufanele dimensioned yokuthi izimpande ibekwe ngokukhululekile kuwo. Indawo yokugoma kumele ahlale ngaphezu komhlaba. I inkathi izimila kudinga ezimbili noma ezintathu efaka umquba nitrate noma urea.

Lezi izihlahla zezithelo zikhula kancane kakhulu, ngakho ukusheshisa ukukhula kwabo ukusiza asebekhulile izinso isihloko, okuyinto kubhekwa iphuzu wabo obuthakathaka. Kuze kube yimanje, ngo-August isuswe amapuleti eziningana eduze amahlamvu engenhla.

Kukhona izinhlobonhlobo eziningana izihlahla zezithelo, kodwa ethandwa kakhulu zintathu kuphela. Columnar apula esihlahleni, inhlobo "mongameli" onikeza izithelo namanzi ngedizethi ukunambitheka ekahle kakhulu izingadi amancane. izithelo zayo isisindo ifinyelele amakhilogramu ikota, aphuzi-mhlophe futhi uvuthwe ngo-Agasti.

Okunye apula columnar - ibanga "Ostankino" futhi "Malukh" - kakhulu ayethanda ukulima ngenjongo kucutshungulwe izithelo. Zinikeza kuze kufinyelele khilogremu eziyisishiyagalombili Isivuno isihlahla ngasinye, kodwa hhayi egcinwe okwesikhathi eside.

Insimu Yase-apula-izihlahla emva kokwehla enjalo iminyaka eyishumi nanhlanu idinga ukushintshwa, ngoba kancane kancane bome out futhi ayisekho abuyiselwe ngalesi sikhathi kalchatka uqweqwe aphansi. Ngenxa yalokho, isivuno uqala wehlise, nakuba komapula bangaphila eminyakeni engamashumi ayisihlanu ezinhle.
