Orkideda oq qoplama paydo bo'lishi o'simlikning biologik muvozanatining buzilishini ko'rsatadi. Asosiy sabablar qo'ziqorin infektsiyalari, xususan, changli chiriyotgan yoki zararkunandalar, masalan, unli hasharotlardir. Bu alomatlarni e'tiborsiz qoldirish to'qima deformatsiyasiga, fotosintezning buzilishiga va epifitning asta-sekin pasayishiga olib keladi.<\/p>\n

Tashxis: Kukunli chiriyotgan va Mealybug<\/h2>\n

To'g'ri davolash strategiyasini tanlash uchun blyashka tabiatini farqlash muhimdir. Kukunli chiriyotgan asosan barg pichog'ining pastki qismida joylashgan unga o'xshash mayda, kukunsimon qatlam sifatida paydo bo'ladi. Mexanik qo'llanilganda, blyashka osongina olib tashlanadi va shikastlangan, ko'pincha sarg'aygan barg to'qimasini ko'rsatadi.<\/p>\n

Unli qo'ziqorinlar tubdan boshqacha tuzilishga ega - paxtaga o'xshash oq bo'laklar. Qo'ziqorinlardan farqli o'laroq, bu shakllanishlar yopishqoqdir. Zararkunanda ikkilamchi infeksiyalar, jumladan, kuyik mog'or rivojlanishi uchun qulay muhit yaratadigan o'ziga xos moddani ajratib chiqaradi. Murakkab holatlarda, barg qo'ltiqlari atrofida harakatlanuvchi mikroskopik nuqtalarga o'xshash lichinkalar to'planadi.<\/p>\n\n\n\n\n\n\n

Xavf omillari va oldini olish<\/h2>\n

Orkide immuniteti tashqi stress omillari ta'sirida zaiflashadi. Agar qishloq xo'jaligi amaliyotlariga rioya qilinmasa, o'simlik zaiflashadi:<\/p>\n

    \n
  • Hujayra devorlarining bo'shashishiga olib keladigan azotli o'g'itlarni haddan tashqari qo'llash.<\/li>\n
  • Havo namligidagi me'yordan keskin og'ish, bu patogenlarning ko'payishi uchun muhitni qulay qiladi.<\/li>\n
  • Sug'orish rejimini buzish, substratda namlikning turg'unligiga va ildizlarning chirishiga olib keladi.<\/li>\n
  • Kastryulkada o'simlik qoldiqlarining mavjudligi, zararkunandalar uchun ko'payish joylarini yaratadi.<\/li>\n<\/ul>\n

    Birlamchi ishlov berish algoritmi<\/h2>\n

    Kasallikning etiologiyasidan qat'i nazar, davolashning birinchi bosqichi o'simlikni sanitariya izolyatsiyasi hisoblanadi. Bu spora yoki hasharotlarning boshqa yopiq o'simliklarga tarqalishini oldini oladi. Harakatlar ketma-ketligi quyidagicha:<\/p>\n

      \n
    1. Ta'sirlangan o'simlikni alohida xonada izolyatsiya qiling.<\/li>\n
    2. Steril asbob yordamida batafsil tekshiruv o'tkazing va ko'rinadigan shikastlanish belgilari bo'lgan barcha to'qimalarni olib tashlang.<\/li>\n
    3. Kesilgan joylarni antiseptik (maydalangan yog'och yoki faollashtirilgan uglerod) bilan davolashga ishonch hosil qiling.<\/li>\n<\/ol>\n

      Kukunli chiriyotganga qarshi kurash usullari<\/h2>\n

      Qo'ziqorinlarga qarshi kurash substratga kompleks yondashuvni talab qiladi. Po'stlog'ining yuqori qatlamini yangi, oldindan sterilizatsiya qilingan material bilan almashtiring. PH ni normallashtirish va qo'ziqorin sporalari faolligini inhibe qilish uchun substrat yuzasiga yupqa yog'och kul qatlamini sepish tavsiya etiladi. Patogen mikroflorani bostirish uchun ildizlar va barglar yuzasida himoya to'sig'ini yaratadigan Bacillus subtilis asosidagi ixtisoslashgan mikrobiologik mahsulotlardan foydalaning.<\/p>\n

      Mealybuglarga qarshi kurash usullari<\/h2>\n

      Unli hasharotlarga qarshi kurash hasharotlarni mexanik ravishda yig'ish va takroriy ishlov berishni talab qiladi. Ko'rinadigan hasharotlarni spirt yoki sovunli suvga botirilgan paxta chig'anoqchasi bilan olib tashlang. Mexanik tozalashdan so'ng, o'simlikni zararkunandalarning asab tizimiga ta'sir qiluvchi biologik insektitsidlar bilan purkang. Samaradorlikni oshirish uchun orkideni 2 soat davomida plastik paketga soling va faol moddaning mahalliy konsentratsiyasini hosil qiling. Birinchi ishlov berishdan keyin tuxumlardan chiqadigan har qanday lichinkalarni o'ldirish uchun protsedurani 10-14 kunlik interval bilan takrorlang.<\/p>","protected":false},"excerpt":{"rendered":"
