Iziphumo zokufudumala kwehlabathi kwiingcambu zezityalo

ukufudumala kwehlabathi kwiingcambu zezityalo

Sithetha ngefuthe lokutshintsha kwemozulu kunye nokufudumala kwehlabathi kokubini kwi-atmosfera nakwizityalo nezilwanyana. Nangona kunjalo, asiva ngeziphumo ze ukufudumala kwehlabathi kwiingcambu zezityalo. Nangona iingcambu ziphantsi komhlaba, zikwachatshazelwa kukufudumala kwehlabathi.

Kweli nqaku siza kukuxelela ukuba yintoni imiphumo yokufudumala kwehlabathi kwiingcambu zezityalo kunye nemiphumo yayo.

Ukufudumala kwehlabathi kwiingcambu zezityalo

izilimo

Nangona kubonakala ngathi ukukhula kwezityalo ezingaphezulu komhlaba kuthintelwa kancinci kukutshintsha kwemozulu, iphephandaba lakutshanje kwi-Science Advances libonisa ukuba kukho utshintsho olubalulekileyo olwenzekayo ngaphantsi komhlaba.

Iqela labaphandi abavela kwiYunivesithi yaseNorth Carolina State (USA) lifumene ukuba ukuhluthwa kwekhabhoni kuya kuba nzima, nto leyo ebangela ukuba kuphume iigesi ezininzi zegreenhouse emoyeni. Iingcali zenzululwazi ziye zafumanisa ukuba izinto ezimbini zemozulu, ukunyuka kwamaqondo okushisa kunye namanqanaba aphezulu e-ozone, zinefuthe elibi kwiingcambu zezityalo zesoya kunye nokukwazi ukusebenzisana ne-microorganisms zomhlaba. Oku kuyakhathaza ngakumbi ngokulinywa kweembotyi zesoya.

Kuyaphawuleka ukuba umaleko womhlaba ophezulu weplanethi, ofikelela kwi-30 cm, uqulethe intabalala yekhabhoni. Iphantse yaphinda kabini imali ekhoyo kwi-atmosfera iyonke.

Abaphandi baqhube uhlalutyo olubanzi lwempembelelo yamanqanaba e-ozone aphakamileyo kunye nokufudumala okwandayo kwizidalwa ezithile eziphantsi komhlaba, ezaziwa njenge-arbuscular mycorrhizal fungi (AMF). Ezi zinto ziphilayo zinoxanduva lokuququzelela ukusebenzisana kweekhemikhali ezithatha ngokufanelekileyo ikhabhoni emhlabeni ngokuthintela ukubola kwezinto eziphilayo. Le nkqubo ikhusela ukukhutshwa kwekhabhoni kwizinto ezibolayo.

Kuqikelelwa ukuba ezi fungi zinokufumaneka kwiingcambu malunga I-80% yazo zonke izityalo ezikhoyo kumphezulu weplanethi. Ngoko ke, ukubaluleka kwayo akunakujongelwa phantsi. Ezi zinto ziphilayo zinendima ebalulekileyo kumjikelo wekhabhoni ngokukhupha ikharbhon kwizityalo nokubuyisela izondlo eziyimfuneko, njengenitrogen, emhlabeni. Lo mjikelo ubalulekile ekukhuleni nasekukhuleni kwazo zonke izityalo.

Ukukwazi ukugcina ikhabhoni

isityalo esikhulayo

Ngokutsho kombhali-mbhali uNjingalwazi uShuijin Hu, ukukwazi ukugcina ikhabhoni kubalulekile ekugcineni imveliso yomhlaba. Oku akubangelwa nje kuphela kwimpembelelo engalunganga yeegesi ze-greenhouse ezibangelwa ukuvuza kwekhabhoni, kodwa nokubaluleka kokuhluthwa kwekhabhoni ngokubanzi.

Abaphandi ababandakanyekayo kuphononongo bahlula iindawo ezininzi zomhlaba, nganye ineenguqu ezahlukeneyo. Ezinye iziza zatyalwa iimbotyi zesoya kwaye ziphantsi kokwanda kobushushu bomoya obumalunga nesithathu ngokukaCelsius (3ºC). Ezinye iziza zavezwa kumanqanaba aphezulu e-ozone, ngelixa elinye icebo laliphantsi kobushushu obuphezulu kunye ne-ozone. Ekugqibeleni, kwakukho indawo yokulawula amasimi eembotyi zesoya engazange ichaphazeleke. Waba yintoni umphumo wolingelo? Iimvavanyo zentsimi zabonisa ukuba Ukunyuka kwe-ozone kunye namaqondo obushushu abangela ukuba iingcambu zesoya zibe zincinci, ngoxa bezama ukulondoloza ubuncwane bazo kunye nezondlo zabo.

Ngokutsho kukaHu, impembelelo ye-ozone kunye nokufudumala kwizityalo ezifana neembotyi zesoya zibalulekile kwaye zinoxinzelelo. Noko ke, oku akuphelelanga nje kwiimbotyi zesoya, njengoko ezinye iintlobo zezityalo nemithi nazo zichaphazeleka. Ukunciphisa isityalo sisiphumo esithe ngqo se-ozone kunye nokufudumala, okuye kwaboniswa ukuba kuyingozi. Izityalo zizama ukwandisa ukufunxa kwazo izondlo, nto leyo ezenza zibe iingcambu zawo zinde kwaye zibhityile. Oku kuyimfuneko njengoko kufuneka baphonononge umthamo omkhulu womhlaba ukuze bafumane izixhobo abazifunayo.

Ukuguqulwa kwendlela yokuziphatha kwezityalo yinto ebonwe kwiimeko ezahlukeneyo.

Iziphumo zokufudumala kwehlabathi kwiingcambu zezityalo

iziphumo zokufudumala kwehlabathi kwiingcambu zezityalo

Isiphumo esithe ngqo sale nkqubo yokuncipha kukuncipha kwefungi ye-arbuscular mycorrhizal kunye nokukhula okukhawulezileyo kwe-hyphae. I-hypha luthungelwano lweeseli ezinde ze-cylindrical ezigqunywe kwi-chitin eyenza imizimba yeziqhamo zezi fungi. Oku kukhawuleziswa kokukhula kukhuthaza ngakumbi ukubola kwaye kwenza kube nzima ukuthinjwa kwekhabhoni. Kufuneka kuqatshelwe ukuba, emva kweelwandle, umhlaba ngowona mhlaba mkhulu wekhabhoni wendalo kwiplanethi yethu, ude ugqithise amandla okubambisa i-carbon dioxide yamahlathi kunye nezinye iintyatyambo. Ngoko ke, ukunciphisa okubonwayo kwiingcambu kufuneka kube yimbangela yokukhathazeka.

Uluhlu lweziganeko ezenzeka phantsi komhlaba alunakubonwa ngeso lenyama, kodwa lunokuba nempembelelo enkulu ekukhuleni kwezityalo, nokuba ihlumela lazo libonakala liqhelekileyo. Iingcali zifumanise ukuba amanqanaba ohlobo oluthile lwe-AMF, iGlomus, ehlile kwindawo engqonge izityalo zeembotyi zesoya. baye bavezwa kumazinga aphezulu okufudumala kunye ne-ozone. Ngokwahlukileyo, uhlobo olwahlukileyo, iParaglomus, lubonise ukwanda kwamanqanaba.

Ngokutsho komphandi, iGlomus ikhusela ikhabhoni ephilayo ekuboleni ziintsholongwane, ngelixa iParaglomus isebenza ngakumbi kwi-assimilation yezondlo. Utshintsho olwenzeka kolu luntu lwalungalindelekanga. Ukongeza, iintlobo ze-arbuscular mycorrhizal fungi ezityalwe kwiimbotyi zesoya ziye zatshintsha ngenxa yotshintsho lwe-ozone kunye namaqondo obushushu aphezulu.

Iqela labaphandi libhengeze injongo yabo yokuqhubeka nokuphanda iinkqubo ezahlukeneyo ezinxulumene nokuhluthwa kwekhabhoni emhlabeni, ngaphezu koko. okunye ukukhutshwa kwegesi yegreenhouse okwenzeka ngaphantsi komhlaba, njengenitrous oxide okanye i-N2O. I-Food and Agriculture Organization yeZizwe eziManyeneyo (i-FAO) iye yanikela ingxelo yokuba i-30 cm yokuqala yomhlaba kwiplanethi inekhabhoni ephindwe kabini kunomoya ojikeleze umhlaba wonke. Nakuphi na ukuncitshiswa kokuthathwa kwekhabhoni kwezi ndawo kunokuthintela iinzame zethu zokunciphisa ezona ziphumo zinzima zokutshintsha kwemozulu.

Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga nemiphumo yokufudumala kwehlabathi kwiingcambu zezityalo.
