Umhlaba wezitshalo zasemanzini noma ezinamanzi amancane ubanzi kakhulu: kukhona ezinye ezihlobisa kakhulu futhi ezilula ukukhula, futhi kukhona ezinye ezihlasela kakhulu. Okunye kokugcina yizinhlobo IMyriophyllum aquaticum, utshani bombala omuhle oluhlaza.
Izinga lokukhula kwalo liyashesha kakhulu, kodwa hhayi lokho kuphela, livimba nezinye izitshalo ukuthi zikhule.
Umsuka nezici
Lesi yisitshalo se-herbaceous esingapheli - sihlala iminyaka eminingana - sizalelwa emaxhaphozini aseNingizimu Melika, futhi sethulwa eNyakatho Melika ngonyaka we-1800. Namuhla sesidume kakhulu ngokusetshenziswa kwaso emanzini. Igama layo lesayensi ngu IMyriophyllum aquaticum, obizwa nangokuthi umsila wamanzi we-fox. Iba neziqu ezijiyile, namaqabunga ku-3-6, ngobude obungu-2-5cm, wombala oluhlaza okhanyayo. Izimbali azithandani, zincane futhi zimhlophe;, futhi isithelo siyinadi elingu-1 kuya ku-2mm ubude.
ESpain kubhekwa njengesitshalo esihlaselayo ngoba ziyingozi enkulu ezitshalweni zomdabu, ezindaweni zokuhlala noma emvelweni. Yafakwa ku-Invasive Alien Species Catalog ngo-Agasti 2, 2013.
Isebenzani?

Isetshenziswa njengesitshalo se-aquarium, kungaba ngaphakathi noma ngaphandle. Inkinga ukuthi ikhula ngokushesha okukhulu futhi kunzima ukuyilawula, ngoba ayinakho ukuncintisana futhi ayikho imishanguzo yokubulala ukhula eyiqeda nya. Ezindaweni ezidabuka kuzo ezinye izinambuzane zidla kuwo, futhi naseFlorida - lapho yethulwa khona - azinankinga enkulu futhi, ngoba izibungu zeminyovu i-Alticini ziyisebenzisa njengokudla; kodwa emhlabeni wonke asinayo leyo nhlanhla.
Ngaphezu kokugcwala ngokweqile, ezinye izizathu zokuthi kungani ukusetshenziswa kwayo kungavunyelwe:
- Ukwanda ko-alga
- Ukwanda komiyane
- Izinkinga zokunisela nokuhambisa amanzi
Ngakho-ke uma uke walingeka ukuthi uthole ikhophi, kungcono ungayithengi 🙂.
