I-Asiatica yisitshalo samanzi asogwini esingapheli, esithwala amabala esihlala ezimweni zamanzi ahlanzekile. Ukubukeka kwayo kungachazwa kanjena:
- isiqu sesigaxa esinamagobolondo amabili noma esinezigaxa ezintathu, esigxiliswa ngokuphelele emhlabathini;
- isiqu sizungezwe inani elikhulu le-subulate, kepha amaqabunga aqondile noma aphambukile kancane, athambekele ekukhanyeni ngasisekelo. Imvamisa ubude babo buhluka kusuka kumasentimitha ayi-10 kuye kwangama-40. Izimbuzi zabo azikho, futhi zona ngokwazo ziyafa ebusika;
- izimpande - ziningi, kepha azinabhuloho;
- ama-sporangia akhiwa phansi kwamaqabunga, emigodini eklanyelwe ngokukhethekile. Ukuba khona kwe-macrosporangia ngameva abukhali (okwenziwe kuma-axils amaqabunga angaphandle) kanye ne-microsporangia ebushelelezi (eyenziwe ngamaqabunga ajulile kunalawo angaphezulu) kuyaphawulwa;
- ingxenye emaphakathi yezinqwaba iqukethe amaqabunga oyinyumba.
Ukushaywa umoya kubhekwa kusukela ngo-Agasti kuya kuSepthemba.
Izindawo zokuhlala
Izinwele zezinwele zase-Asia azivamile emvelweni, ikakhulukazi:
- Isiqhingi saseSakhalin, okungukuthi ezifundeni zaso eziseningizimu nasenyakatho-mpumalanga;
- Iziqhingi zase-Iturup naseParamushir;
- UPrimorsky Krai;
- IKamchatka;
- IJapan neChina.
Indawo engcono kakhulu yokuhlala nokuzalanisa ibhekwa njengamanzi afudumele ngokwanele futhi anesihlabathi esinodaka lwamachibi anamanzi amasha.
Izici ezinomthelela ekwehleni kwenombolo yilezi:
- Ukungcoliswa kwamanzi;
- ububanzi obuncane bemvelo.
Itholakala ekujuleni okungekho ngaphezu kwamasentimitha angama-35. Kubalulekile futhi ukuqaphela ukuthi ingaphakamisa umhlaba bese intanta emanzini. Lesi sitshalo sidinga kakhulu imvamisa yemizimba yamanzi nokubonakala kwamanzi.
Izindlela zokuvikela ezidingekayo ukuhlanzwa kwemizimba yamanzi ezindaweni ezivikelwe lapho kutholakala lolu hlobo. Ngaphezu kwalokho, ukulawula inani labantu kubaluleke kakhulu, okutholakala ngokukhula emanzini abandayo amanzi noma endaweni eshisayo enomswakama enokukhanya okungafani. Kokubili abantu ngabanye kanye nama-rhizomes angatshalwa kabusha - ukutshala kungenzeka ngokukuhlukanisa. Ngokuvamile, le nqubo iyasebenza impela futhi ithatha isikhathi esiningi.
Ngaphezu kwalokho, kubaluleke kakhulu ukuthi izazi zemvelo zenze izindlela ezengeziwe zokuvikela, ikakhulukazi ezindaweni zemvelo ezivikelwe ngokukhethekile.
