La U-Egeria Densa, owaziwa nangokuthi i- isitshalo samanzi esibizwa nge-Elodea, inokukhula okungafinyelela ku-4m ukujula, iziqu zingabaqhubi abafinyelela ku-2m noma nangaphezulu ubude.
Amaqabunga ahlelwe ngo amaqembu amane kuya kwayisishiyagalombiliZingamasentimitha ayi-1 kuye kwayi-4 ubude namasentimitha amabili kuya kwangu-2 ububanzi, zinesiqongo esicijile.
Izici
Kuyinto isitshalo ukuthi inezimbali zombili zesifazane neziduna, ikhiqiza izimbali ezinamamilimitha aphakathi kuka-12 kuya kwangu-20 ububanzi, inamacembe amathathu abanzi, amhlophe, anomumo oyindilinga, isilinganiso esifinyelela kumamilimitha ayi-10 ubude lapho lesi sitshalo singowesilisa, size sifike kumamilimitha ayi-7 uma isitshalo kwabesifazane.
Lesi sitshalo sinesiqu eside ngokwanele esinombala oluhlaza okotshani, amaqabunga amancane anomumo we-lanceolate ahlelwe ngesilinganiso esiphakathi kwemithathu kuya kwemihlanu. Umbala oshubile onamaqabunga kanye neziqu, uwenza ube isitshalo esisetshenziswa kakhulu ezindaweni zasemanzini.
Indawo yokuhlala nokusatshalaliswa
I-Elodea Kuyisitshalo esidabuka emanzini apholile eNingizimu Melika, okwenzeka emazweni afana ne-Argentina, Brazil ne-Uruguay. Ngemuva kokuphunyuka emisebenzini yokulima, kwaba yinto engokwemvelo yokuba isitshalo esihlasela izindawo ezipholile nezishisayo zomhlaba, kufaka phakathi iYurophu, izindawo zaseNingizimu Afrika, i-Australia, i-Asia, iNyakatho Melika kanye neNew Zealand.
Kungenzeka futhi ukuthi thola emachibini ayizinto zokwenziwa noma nakwezemvelo, emithonjeni yezikwele ezithile, emiseleni engasohlangothini olulodwa emizileni ethile, emadamini noma nakulezo zindawo zezikhukhula ngezikhathi ezithile ngenxa yokugcwala kwemifudlana nemifula.
Ukunakekela i- U-Egeria Densa
Kungakuhle ukubeka ukunikezwa kwensimbi okuwuketshezi okungenani usuku olulodwa ngesonto. Lesi sitshalo sikhula ngokushesha okukhulu futhi sikhiphe uhlobo lwezinto ezivimbela ulwelwe oluhlaza okwesibhakabhaka noluhlaza okotshani ukuba lungakhuli.
Ngokukhula okukhulu kangaka, isitshalo siyinkinga lapho ukuthena kungenziwa njaloNgakho-ke, ukuthena kufanele kwenzelwe ukwakheka kanye nokumaka lapho ukukhula kukhulu kakhulu. Kodwa-ke, kuyadingeka ukugwema ukuthena ngokuqhubekayo njengoba i-elodea ivimbela ukuthuthukiswa kwe-algae.
Lesi sitshalo ingashintshwa ekukhuleni ekukhanyeni okukhanyayo futhi ekukhanyeni okuphansi. Uma zikhule ngokukhanya okuningi, iziqu zizoba nombala oluhlaza okotshani futhi ziyokhula zifike kumamitha amabili ubude ngesikhathi esifushane kakhulu. Lapho ikhulele ekukhanyeni okuphansi, ama-internode namaqabunga kuzoba made, isiqu sibushelelezi futhi mncane futhi umbala wesitshalo jikelele uzoba luhlaza ongacunuli.
Okufanelekile, kufanele ibe ne-substrate evumela ukuthi imunce wonke umsoco, kufanele kuhlinzekwe ngesikhutha Ukuze ukwazi ukwenza i-photosynthesize kahle, gcina ukulawulwa kwamanani okushisa kanye namazinga we-pH.
Izifo
I-Chlorosis Yisifo esithinta ukukhula kwe-elodea lapho inhlabathi ine-pH ephezulu kakhulu noma itholakala enhlabathini enamanzi amaningi. Kulula kakhulu ukukhombanjengoba ibangela umbala ophuzi emithanjeni yamaqabunga amasha, kodwa futhi ingavela emaqabungeni amadala. Lapho i-iron chlorosis ibucayi impela, kubangela umbala ophuzi, kanye necrosis emaqabungeni ngisho nasekufeni kwesitshalo.
Uma kwenzeka ukuthi isitshalo sisemhlabathini ompofu, i-chelate encane yensimbi kufanele ingezwe ekuniselweni ukwelapha lesi sifo. Uma kwenzeka amanzi enenkalipho noma i-alkaline, okuhle yilokho amanzi okunisela aphathwa ngomkhiqizo one-asidi. Ezimweni ezibucayi kakhulu ezifana nenhlabathi ene-alkaline noma enamakhalali, ikhambi lokwelapha lesi sifo kungaba ukusebenzisa imikhiqizo eyahlukahlukene yamakhemikhali noma ukufaka enye ingxenye yomhlabathi esikhundleni solunye uhlobo lomhlabathi one-asidi.
