Lapho ukhuluma nge- USalvinia Asikhulumi ngezinhlobo zezitshalo ezithile, kodwa mayelana nohlobo, olwakhiwe ngokuhlukahluka okuningi okunezici ezifanayo.
Namuhla uzokwazi idatha ejwayelekile mayelana ne- USalvinia, kanye nedatha ethile kwezinye zezinhlobo ezaziwa kakhulu ezikhona namuhla. Futhi akufanele sikukhohlwe lokho lezi zitshalo akuzona izinhlobo ezijwayelekile ezidinga inhlabathi ukuze zikhule.
Imininingwane ejwayelekile ye- USalvinia
Ubulembu bamanzi antantayo o USalvinia, isitshalo samanzi esintanta mahhala esingajwayele ukugula nokubola. Kuyisitshalo saminyaka yonke esizodada emanzini ngenxa yenani lomoya ezicutshini zezitshalo. Lo moya owedlulele wenza ifern ibukeke ifiphele ngokubukeka.
Le inketho ethokozisayo futhi ekhula kalula engadini yamanzi futhi izinsiza ekuhlanzweni kwamanzi ngenxa yesici sayo sokuhlunga sokususwa kwezinto eziphilayo lamanzi. Ubulembu bamanzi obuntantayo bungaba ukwengeza okuhle engadini yamanzi noma echibini elinezinhlanzi noma ezinye izidalwa eziphilayo ngenxa yalesi sici sokuhlanza.
Kunokwehluka okuningi phakathi kohlobo lweSalvinia. I- USalvinia wacasuka noma i I-Giant salvinia kungaba ukhula oluhlaselayo olukhula ludlange ezindaweni ezifudumele zomhlaba. Isetshenziswa njenge ubulembu obuntantayo bamahhala bama-aquariums nezici zamanzi ngenxa yemvelo yayo yokuhlobisa ngaphandle kwezimpawu zokuhlasela.
Izinhlobo eziningi ezijwayelekile
USalvinia minima
La USalvinia minima es olunye lwezinhlobo eziyi-12 ezaziwayo zeSalvinia. Abomdabu baseMelika Ephakathi neseNingizimu kanye nase-Antilles, itholakale endle ezifundazweni eziningana eNyakatho Melika.
Ngenxa yobunjalo bayo bokuhlasela inakho uvinjelwe kwezinye zazo, kufaka phakathi iTexas. Ihlobene ne-Azolla, olunye uhlobo lwezitshalo ezintantayo. I- USalvinia minima Kuyaziwa nangokuthi iziphukuphuku zamanzi, ubulembu bamanzi, namanye amagama ahlukahlukene, kepha empeleni kungumbungu ontantayo.
Ngenxa yezici ezithile isitshalo esinazo, kunjalo kuvame ukudida okuningi nge AmaSalvinia natans. Enye indlela yokuyikhomba ukuthola ingilazi yokukhulisa bese ubheka izinwele ezikumaqabunga. Imvamisa, izinwele ezikumaqabunga kaSalvinia bahlangana phezulu ngenhla ngohlobo lwe- «egg beater».
USalvinia wacasuka
La USalvinia wacasuka ungowokuzalwa eningizimu-mpumalanga yeBrazil nasenyakatho ne-Argentina. Ikhula unyaka wonke futhi itholakale eNyakatho, Ephakathi neningizimu-ntshonalanga yeFlorida lapho isuswa khona ngokushesha lapho itholakala. Ikhula ngokushesha futhi ikhiqiza umbhede ominyene ontantayo ebusweni bamachibi, amachibi nemifula.
Lokhu kwehluka okucasulayo i-fern yamanzi entantayo ekhula emanzini ahamba kancane, ecebile ngomsoco, efudumele futhi emnandi. Isabalalisa ngolaka ngezicucu zezitshalo. Ingalinywa ngabanikazi be-aquarium namachibi futhi kwesinye isikhathi ikhishwa ngesikhukhula noma ngokuchithwa ngamabomu.
Kufika iphuzu lapho USalvinia wacasuka ikhula kakhulu kangangokuba inganciphisa kakhulu ukugeleza kwamanzikanye nenani lokukhanya kwelanga ne-oxygen okudingeka amanzi. Ngenxa yalokhu, indawo emnyama futhi emile kuthinta kabi ukuhlukahluka kwemvelo kanye nenala yezinhlobo zamanzi ahlanzekile, kufaka phakathi izinhlanzi ezicwilisiwe nezitshalo zasemanzini.
Ukuhlasela kwe USalvinia wacasuka ingashintsha imvelo amaxhaphozi futhi abangele ukulahleka kwendawo yawo yokuhlala. Ikhetha izindawo zomhlaba ezishisayo, ezisendaweni eshisayo noma ezifudumele zomhlaba futhi ikhula kahle emizimbeni yamanzi ezolile noma ehamba kancane, njengemisele, amachibi, amachibi, imifula eyenqenqemeni nemisele.
Emanzini amile yakha amacansi azinzile antantayo. Ukuhlaselwa kukaSalvinia nakho zibeka engcupheni enkulu imisebenzi yezenhlalo nezomnotho ancike emzimbeni wamanzi avulekile, agelezayo kanye / noma aphezulu.
Izici
Ukubukeka
I-fern yamahhala entantayo enezimpande ezingenampande (yize iqabunga lesithathu elenga libukeka njengezimpande), enoboya, cishe nge-10 cm ubude. Ibonisa ukwehluka okukhulu ekubunjweni nasekuhlelweni kwayo ngokuya ngezimo zokuhlala, njengokutholakala kwesikhala nokutholakala kwezakhi.
Kushiya
Kwenzeka kathathu ngamathathu, yize nazo zingavela ngababili ngababili, kepha ngeqabunga lesithathu lihlukaniswe kahle futhi lilenga, elifana nezimpande.
Lokhu kuyindilinga futhi kufana nobubanzi, kwe amasentimitha amabili ubude, ngesisekelo se-cordate, indawo engaphezulu enezinwele ezi-4 ezinamathiselwe kuzeluleko (kufana nomshayi weqanda), ngaphansi kunoboya.
Izinhlamvu
Ku-spore efana nenathi (isakhiwo esinamaseli amaningi), ekhasa ngaphansi.
Izinzuzo
Izinzuzo zikaSalvinia kufaka phakathi ukunciphisa i-nitrate, kubenza i-nitrate aspirator enkulu emunca emanzini. Yini enye, inikeza indawo yokukhosela i-gazinga, umthunzi wengxenye elawulwayo ye-aquarium yakho yanoma yiziphi izitshalo ezicwilisiwe noma izakhamizi ezikhetha ukukhanya okuncane, futhi njengomthombo wokudla kwezimfanzi.
Nokho, lo akuwona umthombo omuhle wokudla okunempilo kwezidalwa zasemanzini ephakeme, uma kuqhathaniswa ne-duckweed ecebile ngamaprotheni, isibonelo. Endaweni engokwemvelo yayo, noma kunjalo, izodlula i-duckweed, ikhombise ukubusa ezindaweni eziningi zamanzi.
Ukutshala
Ubulembu bamanzi obuntantayo kuyisitshalo esincane esifinyelela ngaphansi kuka-10 cm ukuphakama, kepha ingafinyelela ku-40 cm ububanzi ngokunwetshwa kwayo. Lesi sitshalo sithanda izindawo ezimanzi, ngakho-ke senziwa siphumelele ngokusabela engadini yamanzi futhi sidinga kuphela ukunakekelwa okulingene ukuze siphile.
Indawo yelanga noma umthunzi oyingxenye yokwakheka komhlaba ilungele lesi sitshalo, futhi ikwazi ukumelana nesithwathwa esincane, ngamazinga okushisa aze afike ku-2ºC. Isitshalo esingaqhakazi, sinamahlamvu kuphela futhi singeza umuzwa omncane womoya engadini yamanzi.
Ukutshala iSalvinia, uthele izitshalo ezincane emanzini, isikhathi eside ngemuva kosuku lweqhwa lokugcina endaweni. Lokhu kuzosabalala ngokushesha futhi kudale umgoqo we-moss emanzini.
Lokhu kuzonikeza ingadi ukuthungwa okuthile., ukubukeka okukhanyayo nomoya nge-moss, nesembozo esincanyana kwezinye izidalwa eziphilayo zensimu yamanzi. Isiqu sizokhula sikhiqize amaqabunga amaningi futhi singaba namaqabunga angaphezu kwamashumi amabili entanta ngaso. Ngesinye isikhathi isiqu sizohlukana sikhule sibe izitshalo ezi-20.
Ungakusheshisa lokhu ngokuhlukanisa izitshalo ngesandla ngokuhlukanisa iziqu. Ngingakweluleka ukuthi ushiye okungenani amaqabunga ama-4 esitshalweni ngasinye uma uzama lokhu. Ukukhanya kufanele kube phakathi futhi akudingeki i-CO2. Ukungeza ukukhanya okukhulu kakhulu ne-CO2 kungasiza ekukhuleni.
