Salvinia yoyandama
Salvinia yoyandama, dzina la sayansi Salvinia natans, amatanthauza ferns zam'madzi zapachaka. Malo achilengedwe ali kumpoto kwa Africa, Asia ndi madera akumwera kwa Europe. Kuthengo, imamera mβmadambo amadzi ofunda, okhala ndi michere yambirimbiri komanso mβzigwa.
Ngakhale Salvinia acuminata imadziwika kuti ndi chomera chodziwika bwino cha m'madzi, sichimagwiritsidwa ntchito m'madzi am'madzi. Chowonadi ndi chakuti mitundu ina yofananira imaperekedwa pansi pa dzina ili: eared Salvinia (Salvinia auriculata) ndi giant Salvinia (Salvinia molesta).
Chifukwa chomwe Salvinia yeniyeni yoyandama sichipezeka m'madzi am'madzi ndi yosavuta - moyo umangokhala nyengo imodzi yokha (miyezi ingapo), kenako mbewuyo imafa. Mitundu ina ya Salvinia ndi mitundu yosatha ndipo ndiyoyenera kumera m'madzi am'madzi. (Source Flowgrow)
Chomeracho chimapanga tsinde laling'ono lokhala ndi masamba atatu pamfundo iliyonse (pansi pa petioles). Masamba awiri akuyandama, limodzi pansi pa madzi. Masamba oyandama amakhala m'mbali mwa tsinde, amakhala ndi mawonekedwe ozungulira mpaka centimita imodzi ndi theka. Pamwamba pamakhala tsitsi lowala kwambiri.
Tsamba la pansi pa madzi ndi losiyana kwambiri ndi ena onse ndipo lili ndi cholinga chosiyana. Yasanduka mtundu wa mizu ndipo imagwira ntchito zofanana - imatenga zakudya m'madzi. Kuphatikiza apo, ndi "mizu" yomwe mikangano imayamba. M'dzinja, nyengo yozizira ikayamba, fern imafa, ndipo m'chaka, zomera zatsopano zimakula kuchokera ku spores zomwe zimapangidwa m'chilimwe.
Maonekedwe ndi kukula kwake, Salvinia yoyandama imafanana ndi Salvinia yaying'ono ndipo imasiyana ndi masamba otalikirana okha.
M'madzi am'madzi, zomera zamtundu wa Salvinia zimaonedwa kuti ndizosavuta kuzisamalira. Chinthu chokhacho ndi kuunikira kwabwino. Magawo amadzi, kutentha ndi kuchuluka kwa michere sikofunikira.
Zambiri:
- Miyezo ya kukula ndi yayikulu
- Kutentha - 18-32 Β° Π‘
- Mtengo pH - 4.0-8.0
- Kuuma kwa madzi - 2-21 Β° GH
- Mulingo wowala - wolimbitsa kapena wokwera
- Gwiritsani ntchito mu aquarium - osagwiritsidwa ntchito
