Isithombe: Isitshalo Sika-Anyanisi Esitheleleke Ngesifo Sokubola Okumhlophe Enhlabathini
Kushicilelwe: Ephreli 21, 2026 20:06:32 UTC
Isithombe esiseduze esinemininingwane sesitshalo sika-anyanisi esinesifo sokubola okumhlophe kuka-anyanisi, esibonisa ukukhula kwesikhunta esimhlophe kanye ne-sclerotia emnyama ezungeze isigaxa kanye nezimpande enhlabathini emanzi.

Izinguqulo ezitholakalayo zalesi sithombe
Amafayela ezithombe atholakalayo ukuze alandwe ngezansi awacindezelwe kakhulu futhi anesisombululo esiphezulu - futhi ngenxa yalokho, ikhwalithi ephezulu - kunezithombe ezifakwe ezihlokweni nasemakhasini akule webhusayithi, ezilungiselelwe kangcono usayizi wefayela ukuze kuncishiswe ukusetshenziswa komkhawulokudonsa.

Incazelo yesithombe
Isithombe sendawo esinemininingwane eminingi, esiseduze sibonisa isitshalo sika-anyanisi esingajulile esikhula enhlabathini emnyama, emanzi kancane ngenkathi sibonisa ngokusobala izimpawu ze-Onion White Rot Disease. Ingqikithi yesithombe yi-bulb ka-anyanisi evezwe kancane ephuma ebusweni bomhlabathi. Ezungeze isisekelo se-bulb nendawo yempande kukhona ungqimba oluqinile lwe-mycelium emhlophe, efana nekotini esakazeka ngaphandle ezinhlayiyeni zomhlabathi kanye nezicubu zezitshalo ezibolayo. Kulokhu kukhula kwe-fungus emhlophe, kunezinhlobo eziningi ezincane, eziyindilinga, ezimnyama ezifana nembewu encane noma izinhlamvu zepelepele. Lezi zakhiwo zisakazeke kakhulu eduze kwesisekelo sesitshalo futhi zinamathele ku-fungus mat emboze i-bulb nezimpande.
Ibhalbhu ka-anyanisi ngokwayo ibonakala iphaphathekile futhi ikhazimula kancane, kanti izingqimba zayo zangaphandle zisaphelele kodwa zibonisa izimpawu ezicashile zokuwohloka eduze kwesisekelo lapho ukutheleleka kwesikhunta kusebenza khona kakhulu. Isiqu esingezansi, lapho ibhalbhu ishintshela khona emaqabungeni, sibonisa ukushintsha kombala okuncane kanye nokuba nsundu kancane endaweni yentamo. Kusukela kule ntamo, amaqabunga amaningana ka-anyanisi aluhlaza aqondile anwebeka phezulu futhi aphume kancane ohlakeni. Ngenkathi amaqabunga evame ukuba luhlaza, izihloko zamanye amaqabunga zibonisa izimpawu zokuqala zokucindezeleka, okuhlanganisa ukuphuzi okuncane kanye nokomisa okuncane emaphethelweni.
Uhlelo lwezimpande luvezwe kancane futhi lubonakala ngokucacile ngaphansi kwesigaxa. Izimpande eziningi zibonakala zonakele noma zibola, zibambene nokukhula kwesikhunta. I-mycelium emhlophe izungeza lezi zimpande, yakha ungqimba olujiyile, olufiphele olusakazeka ngaphandle ebusweni bomhlabathi obuzungezile. Umhlabathi ngokwawo ubonakala unama-granular futhi uthambile, owakhiwe ngamaqoqo amancane nezinhlayiya zesihlabathi nezinto eziphilayo. Izingcezu ezincane zomhlabathi zinamathela ku-fungus mat kanye nezicubu zezitshalo ezibolayo.
Esizindeni esifiphele kancane, izitshalo ezengeziwe zika-anyanisi zingabonakala ziphuma enhlabathini, okubonisa ukuthi lesi sitshalo sikhula ngaphakathi kwensimu etshaliwe noma ensimini yezolimo. Ukujula kwensimu okungajulile kugcina isitshalo esithelelekile sigxile kakhulu ngenkathi izitshalo zasezindaweni zangemuva zihlala zingagxilile, kugcizelela izimpawu zesifo phansi kuka-anyanisi oyinhloko. Ukukhanya kwelanga kwemvelo kukhanyisa indawo ngokulinganayo, kugqamisa umehluko phakathi kokukhula kwesikhunta esimhlophe, inhlabathi emnyama, kanye ne-bulb ka-anyanisi ephaphathekile. Ukwakheka okuphelele kubhala ngokubonakalayo izimpawu eziphawulekayo ze-Onion White Rot Disease, ikakhulukazi i-mycelium emhlophe yesikhunta kanye ne-black sclerotia ehlukile eqoqene eduze kwe-bulb nendawo yezimpande.
