I-Azolla filiculoides eyaziwa njenge i-mosquito fern kanye / noma i-fern yamanzi, Kuyinto a i-fern yamanzi obonakala ngokuba ngotshani bonyaka obusayizi omncane impela, obunabantu ngaphakathi obunamandla okukhula ukumboza izindawo ezinkulu kakhulu ezakha ezimweni ezithile, ungqimba oluqhubekayo ebusweni bamanzi kumadama, amachibi ngisho nasezindaweni ze-aquarium , yingakho kubhekwa njenge- ichibi kanye nesitshalo se-aquarium.
Kodwa-ke, ngenxa yokushesha ekhula ngayo, kanye nemithelela eyenzayo emvelweni, kunjalo ihlukaniswa njengezinhlobo zezitshalo ezihlaselayo nolaka emazweni amaningi, iSpain ingenye yawo.
Izici
Lokhu kungakho ukwethulwa kwama-Azolla filiculoides kulowo mthombo akuvumelekile ongowokuzalwa ezweni, ngendlela efanayo nokuhweba, ukuthutha kanye / noma ukuphatha kwayo. Okungenxa yokuthi ingxenye enkulu yezingeniso ezenzeka ngaphakathi kokuphakathi zenziwa ngengozi.
Yisitshalo esidabuka eMelika, ikakhulukazi izifunda zaso ezipholile; enosayizi ukuthi nxazonke 2,5-10cm futhi sinamacembe amise okonxantathu angakwazi ukuntanta phezu kwamanzi.
Ngokuvamile, ine- ukubukeka okuluhlaza futhi okukhangayo, yingakho idume kakhulu njengesitshalo sama-aquariums, lokhu kuyisizathu esikhulu esenza ukuthi ingeniswe ngephutha endaweni ekude nendawo esukela kuyo.
Amaqabunga awo mancane ngosayizi (cishe u-1mm), ziyi-oblong, noma i-ovate, i-sessile (ngaphandle kwesiqu noma i-petiole), ziboshwe ngokujulile ngomunye nomunye, ziboshwe futhi zicindezelwe, okuzivumela ukuba zimboze ngokuphelele ama-ramifications, ngaphezu kwalokho, inomngcele we-membranous futhi osebenzayo .
Ngokufanayo, i-sori yabo ibumbene ngaphakathi kwezakhiwo ezaziwa njenge sporocarps, nazo ezimbozwe ngamaqabunga. Lezi zakhiwo, ngokuhluka kwazo kwesilisa, zibonakala ngokuba yindilinga ngokuma, i-sessile, zodwa futhi zingenazo izikali noma izinwele.
Ngokufanayo, ama-microspores anomumo oyindilinga y zikhula ngamaqembu. Ngokwengxenye yayo nokwehlukile kwayo kwabesifazane, imvamisa i-pyriform, ayinaboya noma isikali, inendawo engaphezulu, ine-megaspore evelele ukuthi inesifo sofuba kakhulu futhi inezakhiwo eziphakeme ezikuvumela ukuthi intante.
Banefayela le- ikhono lokukhula emanzini ane-pH ecishe ibe ngu-5-7, futhi futhi namanzi anzima noma aphakathi nendawo, okushisa kwawo kuphakathi kuka-10-28 ° C. Kubalulekile ukusho ukuthi ama-Azolla filiculoides aluhlaza okotshani futhi mpunga lapho esemncane, ngenkathi lapho efinyelela ekuvuthweni aba bomvana noma abomvu futhi abe nsundu ngokunyama. Yini enye, inezimpande ezinde futhi ezijiyile ngokukhula ngaphakathi kwendawo yayo yasekuqaleni.
Abantu balesi sitshalo unekhono lokususa izinsimbi ezikhona kufayela le- amanzi, okuphakathi kwayo ngokwesibonelo: ithusi, ukuhola, i-chromium, i-nickel kanye / noma i-zinc. Ngemuva kwalokhu, izitshalo ziyavunwa, zomiswe futhi ziphathwe njengemfucumfucu eqinile, ngakho-ke kuvela ukuthi zilawuleka kakhulu ngokuqhathaniswa nodoti oketshezi.
Inentshisekelo enkulu kwezolimo
Ilayisi livame ukutshalwa endaweni enezikhukhula, ngakho-ke emazweni ahlukahlukene ase-Asia, kujwayelekile ukuhlwanyela lesi sitshalo ngaphakathi kwezinsimu ezinikelwe ukulinywa kwelayisi izinyanga ezimbalwa ngaphambi kokuhlwanyela irayisi uqobo.
Lokhu kungenxa yokuthi i-Azolla filiculoides imboza ngokuphelele amanzi, ivimbele ukukhula kokhula, futhi lapho omane befa, banikela nge-nitrogen enhlabathini yezinsimu zezitshalo.
Ngale ndlela kungenzeka ukuvimbela ukusetshenziswa komanyolo wezimboni, okuthi ngaphezu kokubiza, kuvame ukungcolisa ama-aquifers ngenxa ye-nitrogen eyeqile ephuma emhlabathini.
Ekugcineni, futhi kufanele kuthiwe lo fern uba yinkinga, ngoba iyahlasela kakhulu, yize sebethatha izinyathelo ngalolu daba.
