Njengoba sibonile ngezikhathi ezithile, izitshalo zingahlushwa izifo, amagciwane, izinambuzane, njll. Ukuvimbela izitshalo zethu ekuhluphekeni kunezindlela eziningi zokuvimbela futhi uma, nakanjani, sezivele zithelelekile, singazixazulula.
Namuhla ngiza ukuzokhuluma isikhutha. Mayelana nokuthi iyini, singayivimba kanjani, izimpawu esingazibona nezinye izindlela zokwelashwa. Ngabe ufuna ukwazi kabanzi ngayo?
Kuyini iDowny Vine?
Kuzo esinye sezifo esaziwa kakhulu ku-viticulture. Kuyaziwa kakhulu ngemvamisa nobukhali bayo. Yisifo esincike ezimweni zemvelo nokuthi, uma sivuna sona, sikwazi ukuhlasela zonke izitho eziluhlaza zesitshalo somvini, sidale ukulahleka okukhulu ekukhiqizeni amagilebhisi.
Yisikhunta esiqala ukusebenza kwaso entwasahlobo lapho izimo zemvelo zivuma kakhulu futhi singasakazeka kangcono ngenxa yamazinga okushisa aphezulu. Le fungus, cishe cishe yonke, incike cishe ngokuphelele kumswakama wezemvelo, yingakho ekwindla, lapho kuncipha izinga lokushisa, ingena esigabeni sokuphumula futhi ingahlaseli umvini.
Izimo eziphelele zemvelo zesikhunta nezimpawu
Lapho sinesivuno somvini, kufanele sinake ukuthi izimo ezinhle azikho ukuze isikhutha se-Downy sihlasele indawo yethu. Ngaphezu kwalokho, esimweni lapho ikwazi khona ukuhlasela isivuno sethu, kufanele sazi izimpawu zokwenza ngokushesha okukhulu futhi sinciphise izinkinga.
Izimo ezikahle kakhulu zemvelo zokuthi isikhutha sisabalale futhi zisebenze yilezi:
- Shoot ubude obungu-10 cm noma ngaphezulu.
- Ukuwa kwemvula okungenani eyi-10 mm.
- Izinga lokushisa elimaphakathi kuka-10ºC.
Siyazi ukuthi intwasahlobo yisikhathi lapho izitshalo zihluma futhi ziqhakaze khona ngokushesha okukhulu. Ngaphezu kwalokho, kunezimvula eziningi kakhulu futhi ezivamile ezinamazinga okushisa aphezulu. Konke lokhu kwenza Imibandela yokuthi lesi sikhunta sikhiqize futhi sihlasele izitshalo zethu muhle.
Sazi kanjani ukuthi ukutshala kwethu umvini kuthintwe yiMildew? Into yokuqala ukubuka amaqabunga. Amaqabunga athinteka yiMildew angabonakala nge amanye amabala kawoyela ngaphezulu, angahambelana nokufudumala okumhlophe ngaphansi.
Singazibona nezinye izimpawu zesikhunta emahlumela nakumahlumela. Kufanele sibone ukuthi amahlumela agobile kanjani futhi ambozwe ngomfutho omhlophe okwenziwa ngawo amaqabunga. Uma isimo sefungus sinamandla kakhulu, amahlumela angawa.
Ngokuphathelene namaqoqo, okusanhlamvu kungathinteka kokubili ekuqaleni nangokuhamba kwesikhathi. Ekuhlaselweni okuhamba kancane, amabhantshi awambozwa ukufutha, kepha athola umbala onsundu kakhulu. Lokhu kungaba yinkomba yokuthi umvini wethu uthintekile yiMildew.
Yini esingayenza ukuyelapha?
Ngaphambi kokubeka isisombululo, kufanele sibeke ukuvimbela. Uma sisentwasahlobo lapho lesi sifo sithuthuka khona futhi nezimo engizibalulile ngenhla zenzeka, inketho engcono kakhulu ukwelashwa ngokuvikela. Ukuze senze lokhu, kufanele sikhumbule ukuthi izimo lapho le fungus isakazeka khona zisekelwe ekushiseni okuphezulu nomswakama ophezulu. Umswakama ohlobene mkhulu kuno-75% kanti amazinga okushisa aphakathi kuka-12 no-30 degrees alungile., ngoba bakhulisa ukusinda kwabo ngama-25%.
Ngakho-ke, kufanele sithathe izinyathelo ezenza amazinga okushisa nomswakama kungabi kuhle kangako kuMildew. Phakathi kwezenzo esingazenza sithola:
- Njalo hlala insimu lapho umoya ovunguza khona. Ngale ndlela sizogwema umswakama owedlulele futhi sithande umoya opholile wemvelo.
- Sizonciphisa amaqabunga athintekile ukugwema ukuqhubeka nokusabalala.
- Sizogwema umanyolo we-nitrogen okweqile.
- Sizotshala izinhlobo zomvini ezingamelana kakhulu nalesi sifo
Kukhona futhi nokwelashwa ngamakhemikhali kweMildew, kepha sizohlala njalo sikhetha izixazululo zemvelo kakhulu.
