Incazelo
Ngohlobo lwaso, lesi sitshalo singokomndeni wezitshalo ezinemibala yamanzi. Njengomthetho, lesi sitshalo sikhula eNyakatho Melika, kepha ngenxa yokuthandwa kwaso, singabonakala kaningi kuma-aquariums atholakala ezingxenyeni ezahlukahlukene zomhlaba. Okunye futhi okubaluleke kakhulu ukuthi yikhono layo elihle lokukhula ngokushesha, yingakho lesi sitshalo sathola igama laso lesibili - "Isifo Samanzi".
Ngokuqondene neziqu, zinde impela futhi zinamandla okufaka igatsha. Isibonelo, icala larekhodwa ukuthi iziqu zafinyelela ngaphezu kwamamitha amabili ubude. Kuyafaneleka futhi ukugcizelela ubuhle babo obumangalisayo. Amaqabunga e-Elodea anombala oluhlaza okhanyayo ogqamile, oblong, ugoqekile kancane futhi ubonakala ngokusobala.

Ukukhiqiza kabusha
Yize lesi sitshalo sikhula cishe kunoma imuphi umzimba wamanzi, abaningi banesithakazelo embuzweni wokuthi inqubo yokukhiqizwa kwaso yenzeka kanjani. Le nqubo yenzeka ngale ndlela elandelayo: izingxenye zamahlumela, ezifinyelela kumitha elilodwa ubude, ziyahlukaniswa nesitshalo futhi zidluliselwe endaweni ekhululekile efinyelelekayo yemvelo yasemanzini, lapho sezivele ziqala ukuqhakaza khona. Ukukhiqizwa kwayo kabusha e-aquarium kuhluke kakhulu. Kulokhu, le nqubo yenzeka kuphela ngosizo lwe-cuttings, ubude obuncane bayo okufanele okungenani bube yi-200mm.
Kumele uqaphele ukuthi lesi sitshalo singaba ngabesifazane nabesilisa.
Ukuze unqume ubulili, vele ubheke imbali uqobo. Ngakho-ke insikazi inamacembe amathathu, ngaphakathi nangaphandle. Futhi lokhu akushiwo i-raltsy enezinhlamvu ngombala obomvu obomvu. Futhi, abesifazane nabo bane-sepal yama-hues abomvu nokuhlaza.
Izimbali zesilisa zibonakala ngokuba khona kwama-anthers ayi-9, kanti ku-ovary uqobo kunama-ovules angafika kuma-20. Kepha, njengomthetho, ezimweni zethu zezulu, abesilisa abangeni. Ngakho-ke, lesi sitshalo sikhula ezweni laso elingokomlando. Isithombe sesitshalo sesilisa singabonakala ngezansi.

Kunesitatimende esithi i-elodea ikhipha ujusi onoshevu ongaholela ekufeni kukafry. Kepha ngokusho kochwepheshe abaningi, akekho noyedwa kubo owabona lo mkhuba. Ngokuphambene nalokho, ngokususelwa ekubonweni kwabo, singaphetha ngokuthi lapho isitshalo sikhula khona, kuncane kakhulu ukuthi i-turbidity iqoqane. Ngaphezu kwalokho, njengoba sisesitsheni esifanayo nezinhlanzi, lesi sitshalo asidingi noma ikuphi ukusizwa okusizayo, ngoba imikhiqizo yomsebenzi wabo obalulekile yanele ukusebenza kwayo.
Kubalulekile futhi ukuqaphela ukuthi ekukhuleni okunethezeka kwe-elodea, kufanele kugcinwe izimo ezilula, ezibandakanya:
- Ukukhanyisa okukhulu okusizayo, ikakhulukazi ngesikhathi sasebusika.
- Ukugwema ukusebenzisa ngokweqile usawoti wezinhlanzi okwelapha.
- Ukukhishwa kwensimbi endaweni yasemanzini.

Ngaphezu kwalokho, lesi sitshalo siba yindawo yokukhosela enhle kakhulu ethosiwe, isenze isitshalo esisemqoka kuwo wonke umuntu othanda ukuzilibazisa.
Ukuzilungisa nokunakekela akufani nakancane nezinhlobo ezibalulwe ngenhla.
