Eminye imibala enhle ekwindla engadini yethu i- asters . Ukuzikhulela ngezinye izikhathi kudinga amandla amaningi nokubekezela, ngoba i-aster ihlushwa izifo futhi isongelwa izinambuzane eziningi, okusho ukuthi ukulwa nabo kumele kube njalo futhi kuphumelele.
Izifo ze-asters ezingapheli nonyaka
Kubonakala ukuthi i-aster ingaphansi kwezifo ezingaphezu kuka-20, ngaphezu kokuhlaselwa izinambuzane, kodwa ukwelashwa okukhethiwe kahle nokuqothulwa kwezinambuzane kungabhubhisa umphumela wabo oyingozi. Ezinye izifo ziqala ukuphazamisa izithombo kakade emabhokisini, ezinye zivela kuphela ngaphansi kwezimo ezithile zezulu, kanti ezinye zifihlekile kuze kube mzuzu wezimbali. Ake sibheke izinto ezivame kakhulu ezenzeka endaweni yethu yezulu.
Umlenze omnyama
Lesi isilonda se-fungal, okuyinto izitshalo eziningi ne-astra ezibhekene nayo. Lithinta zombili izithombo ngaphambi kokutshala phansi, nezitshalo ezindala. Isibonakaliso sesi sifo esinomsola omnyama ukukhwabanisa kwesitshalo endaweni yomcibisholo, engafinyelela ukuphakama kuka-10-15 cm. Izithombo, njengombuso, zinyamalala ngokushesha kakhulu, zibe izitshalo ezindala kancane kancane ziphele futhi ziwohloke ngokuphelele.
Ukuze kuvikelwe imbewu, imbewu iphathwa ngesisombululo esinamandla se-manganese ngaphambi kokuhlwanyela, ukuyibulala ngokucophelela inhlabathi. Uma izitshalo sezikhulile kakade, ziyasuswa ngokuphelele, zishiswe, futhi umhlaba uthululwa ngesisombululo esisemthethweni sokuvimbela ukusakazeka kwefungus.
I-Mosaic (i-jaundice)
Lesi sifo sesandulela ngculaza asiphazamisi nje kuphela izinkanyezi, kodwa ezinye izitshalo zezimbali. Kubonakala ngokuphuziza kwamaqabunga, okungafani nokungafani kahle - nezindawo ezikhanyayo nezimnyama, lapho igama livela khona. Lesi sifo siqala ngenhloko yomphakathi, kancane kancane sithatha isitshalo sonke. Ama-buds nawo ahlupheka futhi abe nombala ophuzi ophuzi esikhundleni somthunzi okhanyayo. Izitshalo ezigulayo zisuswa empandeni futhi zilahliwe, noma zishiswe, njengezakhi zamakhemikhali azikwazi ukulwa nalesi sifo.
Umkhuhlane we-Powdery
I-plaque, efana nofulawa ongcolile ngeziqu kanye namaqabunga e-aster kubangelwa i-fungus. Kungasuswa ngesisombululo se-sulfur colloidal noma ingxube yesobho. Uma lesi sifo sesakazeke, kungcono ukubhubhisa ukutshala ngokushisa, ngaphandle kwalokho i-mycelium yasebusika iphinde ihlasele ama-asters ngaphansi kwezimo ezinhle.
I-Fusarium
Kusukela kumalungiselelo, kunokuba kunokwenzeka ukucubungula izinkanyezi eziguleni ezifana ne-fusarium wilt, ukunakwa kufanele kufunde i-Readzol, i-cobalt chloride, i-Topsin-M, i-magnesium sulphate. Lesi yisifo esivame kakhulu ku-asters siqala ngamaqabunga e-yellowing nama-wilting, ngemva kwalokho asomile, futhi imivimbo emnyama ensundu ivela ngeziqu. Uma isikhathi singenzi lutho, lesi sitshalo sifa.
Indlela yokuphambanisa asters kusuka izinambuzane?
Ngaphezu kwezifo, izinkanyezi nezinambuzane ezihlukahlukene zisongelwa. Lezi yizi:
- iforamu;
- isi-spider mite;
- ibhulogi;
- i-penny slobbering;
- i-earwig;
- i-astrova iqhwa;
- slug.
Zonke lezi zinambuzane zilimaza izitshalo ezivame ukuluhlaza - ziphuza ama-juice anika ukuphila,
Ukuphalaza nge-chlorophos kuzobhubhisa ukuhlaselwa kwe-scoop, futhi "i-Fundazol" izobhubhisa i-earwig. Ngaphezu kwalokho, phambi kwezinambuzane esakhiweni, kubalulekile ukugcina ukujikeleza kwezitshalo - ungatshali izitshalo iminyaka emibili elandelanayo endaweni efanayo. Kumelwe ukulima umhlabathi ngokujulile futhi ususe ukhula. Ukugcinwa kwemigomo yokuhlanzeka ngezindlela eziningi kuzosindisa insimu yembali ezinkingeni ezinesifo nezifo ezinambuzane-izinambuzane.
