Ukubuka izihlahla zikhula kusuka embewini kuwukuhlangenwe nakho okucebisayo futhi okuyigugu. Naphezu kweqiniso lokuthi namuhla sekuyaziwa ukuthi zihluma kanjani, ngezinye izikhathi kunzima ukukholelwa ukuthi entweni encane kangaka izitshalo zingavela ukuthi, ezimweni eziningi, zidlula amamitha ayishumi, kanti ezinye, njenge-sequoias, zifinyelela ku-116m.
Futhi lokho akusho ngisho nokuthi basengozini kangakanani eminyakeni yabo emibili yokuqala yokuphila. Kulokhu, esinye sezifo eziyingozi kakhulu saziwa ngokuthi i-damping-off, noma ukufa kwezithombo . Uma izimpawu zokuqala sezivele, ngokuvamile akukho lutho olungenziwa, kodwa... bewazi ukuthi kungavinjelwa?
Kuyini?
I-Damping-off, eyaziwa kakhulu ngokuthi ukufa kwezithombo noma i-fungal wilt, iyisifo esibangelwa yizikhunta ezahlukahlukene. Ezivame kakhulu ezindaweni zokukhulisa izihlahla yiBotrytis, iPythium, kanye nePhytophthora, yize ezinye ezifana neSclerotium kanye neRhizoctonia zingenakugwenywa. Lezi zikhunta zithelela imbewu noma izithombo ngokushesha nje ngemva kokuhluma, okubangela ukuba zife.
Yiziphi izimpawu?
Kunezimpawu ezimbalwa okufanele zisenze sisole ukuthi sibhekene nenkinga ye-fungal wilt, noma ukuthi singase sisheshe:
- Imbewu:
- oyisiphukuphuku
- ithembeke kancane kunalokho okufanele kube njalo
- Izithombo:
- ukuncipha kwesiqu
- ukubonakala kwebala elimhlophe nxazonke zesiqu
- ukugqama kweqabunga
Indlela yokuvimbela ukubola?
Naphezu kokuthi kuyingozi kangakanani, kunezindlela eziningana ezilula zokuvimbela. Eyokuqala ihilela ukusebenzisa i-substrate entsha ephinde ikhuthaze ukugeleza kwamanzi okusheshayo , njenge-vermiculite noma, uma kuthanda, i-peat exutshwe ne-30% perlite noma izinto ezifanayo.
Kubaluleke kakhulu futhi ukusebenzisa i-fungicide . Ngokwazi kwami, ngincoma ukwelapha imbewu nge-fungicide spray ngaphambi kokuhlwanyela, bese kuthi, uma isihlwanyelwe, ufafaze i-powdered sulfur (noma i-fungicide futhi uma kusehlobo) phezu kobuso be-substrate.
Okokugcina, umbhede wembewu kufanele ugcinwe ngaphandle futhi uniselwe kahle , uqaphela ukugwema ukugcwala kwamanzi. Kokubili ukungabi nomoya kahle kanye nomswakama ophezulu kukhuthaza ukukhula kwesikhunta, ngakho-ke kumele kuthathwe izinyathelo ngaphambi kokuba kuvele.
Ingabe isitshalo esigulayo singabuyiselwa?
Uma izimpawu sezivele, isitshalo kumele siphathwe ngokushesha nge-fungicide, kodwa lokhu akuqinisekisi impumelelo. I-fungi iyi-microorganisms eyinkimbinkimbi, futhi imikhiqizo etholakalayo ayikakayiqedi ngokuphelele; ngakho-ke, ngeshwa, kuvame kakhulu ukuthi izitshalo zife ngisho nangemva kokwelashwa.
Ngethemba ukuthi ikusebenzele futhi ungaba nokuhlwanyela okuhle nokujabulisayo kusukela manje kuqhubeke.
