Bodring hosilni tezda yo'q qiladigan bir qator qo'ziqorin kasalliklariga moyil. Patogenlarning tabiatini tushunish simptomlarni erta aniqlash va tegishli qishloq xo'jaligi choralarini amalga oshirish imkonini beradi. Infektsiyalar ko'pincha tuproqda saqlanib qoladi yoki urug'lar orqali yuqadi, bu esa himoya qilish uchun kompleks yondashuvni talab qiladi. Profilaktik davolash va mikroiqlimni nazorat qilishning kombinatsiyasi orqali izchil natijalarga erishiladi.<\/p>\n

Ildiz chirishi<\/h2>\n

Fusarium so'lishi va traxeomikoz barcha turdagi tuproqlarga moslashadigan Fusarium turkumidagi tuproqda yashovchi zamburug'lar tufayli yuzaga keladi. Alomatlar gullash bosqichida barg xlorozi va keyinchalik kurtaklarning so'lishi orqali paydo bo'ladi. Qo'ziqorin urug'larda yillar davomida saqlanib qolishi mumkin, shuning uchun hatto steril substrat ham patogendan to'liq xalos bo'lishni kafolatlamaydi.<\/p>\n

Infektsiyaning asosiy manbai tuproqdagi zararlangan urug'lar va o'simlik qoldiqlaridir. Qo'ziqorinlarning o'sishi haroratning keskin o'zgarishi va tuproqning haddan tashqari namligi bilan kuchayadi. Profilaktika uchun almashlab ekish va o'tgan yilgi barglardan maydonni yaxshilab tozalash kerak.<\/p>\n

\"Bodringning<\/p>\n

Pitium chirishi asosan yosh o'simliklarga ta'sir qiladi va qora oyoqqa olib keladi. Ildizlarda nekrotik torayishlar paydo bo'ladi, ular vaqt o'tishi bilan qorayadi va ildiz tizimini yo'q qiladi. Og'ir infeksiya holatlarida yer usti qismi oq mitseliy bilan qoplanishi mumkin.<\/p>\n

Barg kasalliklari<\/h2>\n

Mog'orli chiriyotgan yoki peronosporoz tezda jigar rangga aylanadigan burchakli sariq dog'lar sifatida paydo bo'ladi. Bargning pastki qismida qo'ziqorin sporalaridan iborat binafsha qoplama hosil bo'ladi. Kasallik issiqxonalarda yuqori namlikda tez tarqaladi.<\/p>\n

\"Bodring<\/p>\n

Kukunli chiriyotgan barg pichog'i va poyalarning ikkala tomonida oq qoplama paydo bo'lishi bilan tavsiflanadi. Barglar deformatsiyalanadi, jingalaklanadi va asta-sekin quriydi, bu esa mevalarning oziqlanishini buzadi. Issiqxonalarda infeksiya ochiq teshiklar orqali havo oqimlari orqali tarqaladi.<\/p>\n

\"Bodring<\/p>\n

Askoxitoz barg dog'i issiqxona o'simliklarining eng xavfli kasalligi bo'lib, o'simlikning qon tomir tizimiga ta'sir qiladi. Barglarda qora nuqta (piknidlar) bo'lgan jigarrang dog'lar paydo bo'ladi, ular orqali infeksiya issiqxona bo'ylab tarqaladi. Poyalarning zararlangan joylari tezda nobud bo'ladi va o'simlik ozuqa moddalaridan mahrum bo'ladi.<\/p>\n

\"Bodring<\/p>\n

Xavflarni minimallashtirish uchun haroratni qat'iy nazorat qilish va namlikning turg'unligidan qochish juda muhimdir. Toza havoning doimiy ravishda ta'minlanishi qo'ziqorin kasalliklarining avj olish ehtimolini kamaytiradi. Chidamli navlar va duragaylardan foydalanish himoya qilishning asosiy usuli bo'lib qolmoqda.<\/p>\n

Bodringni patogen zamburug'lardan qanday himoya qilish kerak<\/h2>\n

Samarali himoya muntazam profilaktik ishlov berish va optimal ozuqaviy muvozanatni saqlashga bog'liq. Biologik mahsulotlar zararli moddalarning hosilda to'planishiga yo'l qo'ymasdan patogen populyatsiyasini nazorat qilishga yordam beradi. Ob-havo sharoitlariga qarab ishlov berish chastotasini sozlash muhimdir.<\/p>\n\n\n\n\n\n\n

  • Qovoqdan keyin bodring ekmaslik orqali almashlab ekishni mashq qiling.<\/li>\n
  • Shamollatishni yaxshilash uchun muntazam ravishda pastki, eski barglarni olib tashlang.<\/li>\n
  • Mavsum tugaganidan keyin issiqxonani dezinfektsiya qiling.<\/li>\n<\/ul>\n

    Tez-tez so'raladigan savollar<\/h2>\n

    Ta'sirlangan o'simlikni to'liq davolash mumkinmi?<\/h3>\n

    Bodringning qo'ziqorin infektsiyalarini to'liq davolash deyarli imkonsiz, shuning uchun asosiy e'tibor sporalarning tarqalishini cheklash va o'simlikning sog'lom qismlarini himoya qilishga qaratilgan.<\/p>\n

    Biopreparatlar bilan profilaktika qanchalik tez-tez o'tkazilishi kerak?<\/h3>\n

    Barqaror sharoitlarda davolash har 15 kunda bir marta amalga oshiriladi; uzoq muddatli yomg'ir va yuqori namlik paytida interval 7 kungacha qisqartiriladi.<\/p>\n

    Tuproqning kislotaligi chiriganlikning rivojlanishiga ta'sir qiladimi?<\/h3>\n

    Ha, patogen zamburug'lar kislotali tuproqlarda yaxshi rivojlanadi, shuning uchun neytral pH ni saqlab qolish muhim profilaktika chorasidir.<\/p>","protected":false},"excerpt":{"rendered":"
