Interesting omfisi - Salvinia natans

UFern Salvinia natans - encinane, kwakudada phezu kwamanzi imizimba zezityalo amanzi obuphezu usapho Salvinievyh. Olu hlobo iintlobo sodidi Salvinia - ekhula kuphela kummandla Russian Federation. Isityalo isoloko ulinywa nje akwariyam.

Salvinia natans: isakhiwo kunye nenkangeleko

Le omfisi yonyaka isiqu obhityileyo, afikelele cm elinesihlanu ubude kunye nokuba kwi node ngalinye whorls ezintathu igqabi. Isiqu kwakudada phezu kwamanzi. amaphepha amabini okuqinileyo yalo ovate-okweqanda imilo kancinci intliziyo ezimilise-base. Bona zinezihloko iintsumpa ukuba obuphezu iqulathe isipha kweenwele ezimfutshane zamafu. Umphezulu esezantsi ngamagqabi unalo kwintsunguzi cover iinwele ezimdaka ubambe amaqamza. Oku kwenza Salvinia egcinwe phezu kwamanzi. iphepha wesithathu eliba, dissected kwi intshebe ixhonti kwaye wabelane efana kakhulu ngembonakalo kwiingcambu. Enyanisweni, yena wenza nje imisebenzi iingcambu wanyisa amanzi kunye nezondlo, kwaye kananjalo omeleza i omfisi.

Kwempilo Salvinia lencopho

Emazantsi amagqabi phantsi kwamanzi, kukho amaqela ezine ukuya kwezisibhozo ukulenza sori. Ezinye zazo ziqulathe oyindoda olukhulu kunye microsporangia yaye kamva akhiwa futhi gametophytes ababhinqileyo. megasporangia nganye kwakhiwa megaspory ezine, kodwa iphuhlise omnye kuphela. Ngokuqhelekileyo, ngeendlela microsporangia amathandathu microspores ezine.

Njengoko umthetho, ekwindla sori iwe kwaye iye kuhlala ezantsi ichibi. Apho ndidlulise nobusika, kwaye emthonjeni ekutshatyalalisweni iqokobhe yabo. Ama ziyabuya phezu kwamanzi kunye zintshule. Emva waphula udonga ifomu ama microspores trehkletochny gametophyte oyindoda aze wabumba iiseli ezimbini spermatogenic kunye ezimbini nokuphepha zaso. Ngamnye kubo kuvelisa isidoda ezine. Entshulayo, megaspory kwakhona waphula iqokobhe ukwenza gametophyte ababhinqileyo. Kuye kwasekwa archegonium ezintathu, kodwa emva kokukhulelwa senzeka kubo omnye kuphela.

Ummandla lonikezelo

Salvinia natans enoluhlu entle ngokubanzi: oko kuxhaphake emanzini Afrika, imimandla ephakathi yaye emvula Asia, ngokunjalo akumzantsi nombindi Europe. Ngomhla kummandla Russian Federation, lo omfisi kakhulu efumaneka ngasezantsi inxalenye baseYurophu, eMpuma Ekude, Western eSiberia. Salvinia lencopho zimandla amanzi ngamanzi olucothayo ukugeleza okanye umile, amaxesha amaninzi oko kunokubonwa kwi oxbows yemilambo emikhulu Russian.

Ukusetyenziswa kunye nokubaluleka

On kumphezulu amadama esebenzayo omfisi-ezifana, kunye nezinye iintlobo, Salvini, yenza iintshinyela ezishinyeneyo apho ukufikelela yokukhanya umzimba emanzini, nto leyo ngokufuthi ekhokelela utshintsho okubonakalayo ichibi iimeko zokusingqongileyo block. Ngenxa yoko, kumazwe amaninzi kugqalwa eyingozi Salvinia izityalo zokudada. Noko ke, kukho kule omfisi kunye neepropati iluncedo, umzekelo, iintshinyela yayo njengendlela yokusabela elihle kakhulu Qhotsa iintlanzi.

Njengoko kukhankanyiwe ngaphambili, Salvinia ezidadayo ezilinyelwa izityalo Aquarium. Noko ke, oko liyangxengwa, kungekuphela nje into ethile isikhongozeli, leyo iqulathe intlanzi, kodwa nje shader elungileyo zendalo nezinye izityalo kukhetha udlulele ukukhanya.

Umxholo omfisi

Kungcono ukubeka Salvinia indiza akwariyam efudumeleyo epholileyo okanye emvula. Ngu ngokoMthetho umxholo yeemfuno ezizodwa zesityalo ayibonisi. Kuba ayinamsebenzi na lukhuni amanzi, nokuba iasidi - yaye soft and hard amanzi omfisi ikhula kakuhle ngokulinganayo. Lobushushu ngaphakathi etankini kufuneka kugcinwe kwi ubuncinane 24 degrees Celsius. Ukuba amanzi yothani izidanga kuphela ku-20, ukukhula kwezityalo ehla (amagqabi abe ezincinane), kodwa akayeki ngokupheleleyo.

Ukuba tank wakho une Salvinia ezidadayo, endaweni amanzi rhoqo. Njengoko izixhobo ukulayita itanki ekucetyiswa fitolampy ukuba amandla watts ezintathu ilitha nganye, kunye nezibane ezibengezelayo. Ukuba usebenzisa ibhalbhu ezingqengezelayo, ngoko qiniseka ukuba amandla abo yayincinane, kungenjalo uya koma phezulu emoyeni.
