Xa uthetha nge USalvinia Asithethi ngohlobo oluthile lwesityalo, kodwa malunga nohlobo, olwenziwe ngokwahluka okuninzi okunempawu ezifanayo.
Namhlanje uya kuyazi idatha ngokubanzi malunga USalvinia, kunye nedatha ethile kwezinye zezona ntlobo zaziwayo zikhoyo namhlanje. Kananjalo akufuneki siyilibale loo nto ezi zityalo azizizo iindidi eziqhelekileyo ezifuna umhlaba ukuze zikhule.
Idatha ngokubanzi USalvinia
Ubumanzi bamanzi adadayo o USalvinia, sisityalo samanzi esihamba ngokukhululekileyo esingadibaniyo nezifo nokubola. Sisityalo sonyaka esiya kudada emanzini ngenxa yobungakanani bomoya kwinyama yesityalo. Umoya ogqithisileyo wenza ukuba i-fern ibonakale ibukeka ngathi ibukeka.
Olu khetho lunomdla kwaye kulula ukuba lukhule kwigadi yamanzi kwaye Uncedo ekucocweni kwamanzi ngenxa yendlela yokuhluza yokususa izinto eziphilayo zamanzi. I-moss yamanzi edadayo inokuba lulongezo oluhle kwigadi yamanzi okanye echibini elinentlanzi okanye ezinye izidalwa eziphilayo ngenxa yeli candelo lokucoca.
Kukho umahluko omkhulu phakathi kweentlobo zeSalvinia. Inkqubo ye- USalvinia wacaphuka okanye Isalvinia enkulu inokuba lukhula olungafunekiyo olukhula ngamandla kwiindawo ezifudumeleyo zehlabathi. Isetyenziswa njenge I-moss yasimahla yokudada emanzini kunye neempawu zamanzi ngenxa yendalo yokuhombisa ngaphandle kweempawu ezizizo.
Uninzi lweentlobo eziqhelekileyo
USalvinia minima
La USalvinia minima es Enye yeentlobo ezili-12 ezaziwayo zeSalvinia. Umthonyama kuMbindi nakuMzantsi Merika nakwii-Antilles, ifunyenwe endle kwiindawo ezininzi eMntla Melika.
Ngenxa yobume bayo obungenayo iye yavalwa kwezinye zazo, kubandakanya iTexas. Inxulumene neAzolla, olunye uhlobo lwezityalo ezidadayo. Inkqubo ye- USalvinia minima Kukwaziwa nangokuthi ngama-spangles amanzi, i-moss yamanzi, kunye namanye amagama ahlukeneyo, kodwa eneneni iyifern ejikelezayo.
Ngenxa yeempawu ezithile zesityalo, ithande ukudida kakhulu nge AmaSalvinia natans. Enye indlela yokuchonga kukufumana iglasi yokukhulisa kwaye ujonge iinwele ezisemagqabini. Ngokuqhelekileyo, iinwele kumagqabi eSalvinia beza kunye phezulu ngohlobo «iqanda beater».
USalvinia wacaphuka
La USalvinia wacaphuka Uzalelwe kumazantsi mpuma eBrazil nasemantla eArgentina. Ikhula unyaka wonke kwaye ifunyenwe eMantla, kuMbindi nakuMzantsi-ntshona eFlorida apho ipheliswa ngokukhawuleza xa ifunyenwe. Ikhula ngokukhawuleza kwaye ivelise isigubungelo sokudada esixineneyo phezu kwamachibi, amachibi kunye nemilambo.
Lo mahluko ucaphukisayo I-fern yamanzi edadayo ekhula emanzini acothayo, zizityebi kwizondlo, zifudumele kwaye zimnandi. Isasazeka ngamandla kusetyenziswa iziqwenga zezityalo. Inokulinywa yi-aquarium kunye nabanini bamachibi kwaye ngamanye amaxesha ikhutshwe kukukhukula okanye ukuchitheka ngabom.
Kuza inqaku apho USalvinia wacaphuka ikhula kakhulu kangangokuba inokunciphisa kakhulu ukuhamba kwamanzi, kunye nenani lelanga kunye neoksijini efunekayo emanzini. Ngenxa yoku, imeko emnyama kunye nexineneyo ichaphazela kakubi iyantlukwano kunye nobuninzi beentlobo zamanzi acocekileyo, kubandakanya neentlanzi ezifakwe emanzini kunye nezityalo zasemanzini.
Uhlaselo lwe USalvinia wacaphuka inokutshintsha i-ecosystems yemigxobhozo kwaye ibangele ukulahleka kwendawo yokuhlala. Ikhetha indawo ezishushu, ezishushu okanye ezishushu zomhlaba kunye ikhula kakuhle kwimizimba yamanzi ezolileyo okanye ecothayo, njengemisele, amachibi, amachibi, imilambo eyonqenqemeni nemijelo yamanzi.
Kumanzi amileyo yenza iimethi ezidadayo ezizinzileyo. Uhlaselo lukaSalvinia nalo zibeka emngciphekweni omkhulu kwimicimbi yezentlalo noqoqosho ezixhomekeke kwimizimba yamanzi avulekileyo, aqukuqelayo kunye / okanye akumgangatho ophezulu wamanzi.
Izixhobo
Inkangeleko
Ifern yasimahla edadayo engenazimpande (nangona igqabi lesithathu elijingayo lifana neengcambu), Uboya, malunga ne-10 cm ubude. Ibonisa umahluko omkhulu kubume bayo kunye nolwakhiwo ngokuxhomekeke kwiimeko zokuhlala, ezinje ngendawo kunye nokufumaneka kwezondlo
Amagqabi
Ivela kathathu ngesithathu, nangona zinokubonakala zimbini ngambini, kodwa ke igqabi lesithathu lisuswe kakuhle lize lixhonywe, lifana neengcambu.
Oku kujikelezwe kwaye kubanzi elliptical, iisentimitha ezimbini ubude, nesiseko se-cordate, umphezulu ongaphezulu oneenwele ezi-4 eziqhotyoshelwe kwiingcebiso (Iyafana nebetha iqanda), shaggy ngaphantsi.
IiSpores
Kwisipore esifana nenathi (ubume obunemibala emininzi), ekhasa ngaphantsi.
Izinzuzo
Izibonelelo zikaSalvinia kubandakanya ukunciphisa i-nitrate, ibenza i-nitrate aspirator enkulu eyifunxa emanzini. Yintoni egqithisile, ibonelela ngendawo yokuhlala ngefry, umthunzi wecandelo elilawulwayo le-aquarium yakho kuso nasiphi na isityalo esifakwe emanzini okanye abemi abakhetha ukukhanya kancinci, nanjengomthombo wedlelo le-shrimp.
Nangona kunjalo, lo ayingowona mthombo mkhulu wesondlo kwizidalwa zasemanzini ephezulu, xa kuthelekiswa ne-protein-rich duckweed, umzekelo. Kwindawo yayo yokuhlala yendalo, nangona kunjalo, iyakoyisa idadaweed, ibonakalise ukuba ibalasele kuninzi lwamanzi.
Ukutyala
Ubulembu bamanzi adadayo Sisityalo esincinci esifikelela kubude obungaphantsi kwe-10 cm ubude, kodwa inokufikelela kububanzi obungama-40 cm kunye nolwandiso lwayo. Isityalo sithanda indawo ezinomswakama, ngenxa yoko sigqibelele ngokunikezelwa kwigadi yamanzi kwaye sifuna ulondolozo olulinganiselweyo ukuze siphile.
Indawo yelanga okanye umthunzi okhethekileyo womhlaba ilungele esi sityalo, kwaye iyakwazi ukumelana neqabaka ezipholileyo, namaqondo obushushu asezantsi ukuya ku -2ºC. Sisityalo esingatyatyaliyo esinamagqabi kuphela kwaye songeza umoya omncinci kwigadi yamanzi.
Ukutyala iSalvinia, galela izityalo ezisencinci emanzini, kudala emva komhla weqabaka lokugqibela kuloo ndawo. Ezi ziya kusasazeka ngokukhawuleza kwaye zenze isithintelo moss emanzini.
Oku kuya kunika igadi ubume obuthile., ukukhanya okukhanyayo kunye nomoya kunye nobulembu, kunye nesigqubuthelo esibhityileyo kwezinye izidalwa eziphilayo kwigadi yamanzi. Isiqu siya kukhula sivelise amagqabi amaninzi kwaye sinokuba namagqabi angaphezu kwama-20 adadayo ecaleni kwaso. Ngexesha elithile isiqu siya kwahluka sikhule sibe zizityalo ezi-2.
Ungakukhawulezisa ukwahlulahlula izityalo ngesandla ngokwahlula iziqu. Ndikucebisa ukuba ushiye ubuncinci amaqabunga ama-4 kwisityalo ngasinye ukuba uzama oku. Izibane kufuneka zibe phakathi kwaye akukho CO2 iyafuneka. Ukongeza ukukhanya okukhulu kunye ne-CO2 kunokunceda ukukhula.
