Ekutshaleni u-anyanisi oluhlaza, u-garlic, ama-leeks, u-anyanisi kanye neminye imifino ka-anyanisi negalikhi, ukwenzeka kwephuzu elomile kulula ukwenzeka. Uma ukulawulwa kungalawulwa kahle, inani elikhulu lamaqabunga esitshalo sonke liyokoma. Ezimweni ezimbi kakhulu, insimu izoba njengomlilo. Inomthelela omkhulu esivunweni, futhi ezimweni ezimbi kakhulu, ingabanga isivuno. Iyini imbangela yalokhu nokuthi ungakuvimbela kanjani? Namuhla, ngingathanda ukuncoma i-fungicide enhle kakhulu kuwo wonke umuntu, enomthelela ovelele kakhulu ekuvimbeleni nasekulawuleni u-anyanisi oluhlaza nogalikhi.
1. Izimbangela zethiphu elomile
Kunezizathu eziningi zamathiphu omile wemifino ye-anyanisi negalikhi, ikakhulukazi ye-physiological and pathological. Izeluleko ezomile ezinezakhiwo ezinhle ze-physiological ikakhulukazi ngenxa yesomiso nokushoda kwamanzi, futhi amathiphu omile we-pathological abangelwa ikakhulukazi isikhunta esimpunga kanye nokubola. , Isizathu esibaluleke kakhulu sethiphu elomile ekukhiqizeni isikhunta esimpunga kanye ne-blight.
2. Izimpawu eziyinhloko
Isikhunta esimpunga esibangelwa u-anyanisi oluhlaza, u-garlic, i-leek nokunye U-anyanisi kanye nemifino kagalikhi ucezu olomile ngokuvamile “uluhlaza okomile”, ekuqaleni, emaqabunga kumila amachashazi amaningi amhlophe, lapho izinga lokushisa nomswakama kufaneleka, amabala esifo asakazeka eqabungeni. thipha phansi, okuholela ekomeni kweqabunga. Uma umswakama uphezulu, ungqimba olukhulu lwesikhunta olumpunga lungakhiwa emaqabunga afile.
Amathiphu omisiwe ka-anyanisi oluhlaza, u-garlic, i-leek kanye neminye imifino ebangelwa isifo ngokuvamile "emhlophe eyomile". Ekuqaleni kwalesi sifo, amachashaza aluhlaza namhlophe avela emaqabunga, aphenduka amachashaza ampunga namhlophe ngemva kokunwetshwa, futhi wonke amaqabunga ayabuna ekugcineni. Uma imvula noma umswakama uphezulu, isifo sikhula isikhunta esinoboya obumhlophe; Uma isimo sezulu somile, isikhutha esimhlophe siyanyamalala, siklebhule i-epidermis futhi sibone i-mycelium emhlophe enoboya. Uma isifo sibucayi, insimu yomile, njengomlilo.
3. Imbangela yesifo
Ngaphansi kwezimo zokushisa ezifanele, umswakama ophezulu yisona sizathu esiyinhloko sokwenzeka nokusabalala kwe-botrytis kanye ne-blight. I-Botrytis cinerea kanye ne-Phytophthora ikakhulukazi ngesikhathi sasebusika noma ihlobo emhlabathini onamathele emzimbeni ogulayo. Lapho izinga lokushisa nomswakama kufanelekile, amagciwane e-pathogenic asele emzimbeni ogulayo aqala ukuhluma, akhiqize inani elikhulu le-hyphae ne-conidia, elihlasela umhlabathi. Emzimbeni ophethe, futhi amunce imisoco kumaseli aphethe noma amaseli ukuze akhule futhi azalane.
Le conidia noma i-mycelium isakazeka ensimini ngomoya, imvula, amanzi okunisela, njll., futhi iyaqhubeka nokuthelela ezinye izitshalo. Ngaphansi kwezimo ezifanelekile zokushisa nokuswakama, ukusabalala kusabalala ngokushesha okukhulu, futhi ngokuvamile kungabangela ukwenzeka okukhulu ezinsukwini ezingaba ngu-7.
4. Izindlela zokuvimbela
(1) khetha izinhlobo ezimelana nezifo.
( 2), hlanza ingadi, susa amagciwane kusenesikhathi ukuvikela ukusabalala kwamagciwane.
(3), naka amanzi endle, vimbela amanzi asendle.
(4), hlakulela izithombo eziqinile, sebenzisa umanyolo omningi, ukufaka i-nitrogen, i-phosphorus, umanyolo we-potassium, uthuthukise ukumelana nezifo zezitshalo.
(5), isifutho sokuqala50% carbendazimumphumela we-liquid muhle. 6. Hlanza izinsalela ezigulayo ensimini ngesikhathi emva kokuvunwa kuka-anyanisi, futhi uzibhubhise phakathi nendawo.
