Qora oyoq - bu pomidor ko'chatlarini bir necha kun ichida yo'q qilishi mumkin bo'lgan hiyla-nayrangli qo'ziqorin kasalligi. Professional agronomlar bu patogen kompleksni jigarrang chirish deb atashadi. Infektsiya ildiz bo'yinbog'idan boshlanadi: to'qimalar yumshoq, suvli, qoraygan va ingichka bo'ladi, shundan so'ng o'simlik tuproq yuzasida "sinadi".<\/p>\n

\"Pomidor<\/p>\n

Kasallik qo'zg'atuvchisi tuproq zamburug'lari bo'lib, ular avlodga mansub. Pitiy<\/em>, Rizoktoniya<\/em> \u0438 Fitoftora<\/em>. Ular tuproqning yuqori qatlamida doimiy ravishda mavjud, ammo faqat namlik va harorat muvozanati buzilganda faollashadi. 2026-yilgi dunyoda, ko'plab bog'bonlar tijorat substratlaridan foydalanganda, patogenlarning sifatsiz tuproq orqali kirib kelish xavfi ortadi, shuning uchun mutaxassis yondashuvi qishloq xo'jaligi amaliyotlariga qat'iy rioya qilishni talab qiladi.<\/p>\n

INFEKTSION belgilari: tahdidni qanday aniqlash mumkin<\/h2>\n

\"Qora<\/p>\n

Kasallikni erta aniqlash juda muhim. Mana nimalarga e'tibor berish kerak:<\/p>\n

    \n
  • Poyasi deformatsiyasi:<\/strong> Ildiz zonasida torayish aniq ko'rinadi, jigarrang yoki to'q jigarrang rangga bo'yalgan.<\/li>\n
  • So'lish belgilari:<\/strong> Nam tuproqda ham o'simlikning yuqori qismi turgorni yo'qotadi, barglar sarg'ayadi va burishadi, chunki poyaning qon tomir tizimi nekroz tufayli torayadi.<\/li>\n
  • Mahalliylashtirish:<\/strong> Zarar ildiz bo'yinidan boshlanadi, lekin tezda ildizlarga tarqaladi, bu esa o'simlikni substratdan olib tashlashni osonlashtiradi.<\/li>\n<\/ul>\n

    Favqulodda choralar: kasal ko'chatlarni saqlab qolish mumkinmi?<\/h2>\n

    \"Pomidorlarda<\/p>\n

    Agar siz chirish alomatlarini sezsangiz, vaqt juda muhim. "Uni davolang va unuting" yondashuvi ish bermaydi - siz qat'iy algoritmga amal qilishingiz kerak:<\/p>\n

      \n
    1. Yong'in manbasini izolyatsiya qilish:<\/strong> Kasal o'simlik darhol tuproq bo'lagi bilan birga olib tashlanishi kerak, u bilan ifloslangan tuproq bilan aloqa qilgan bo'lishi mumkin bo'lgan 2-3 ta qo'shni ko'chatni olib ketish kerak.<\/li>\n
    2. Teshikni dezinfeksiya qilish:<\/strong> Olib tashlash joyi kaliy permanganatning kuchli eritmasi (to'q pushti rang) yoki mis asosidagi fungitsid bilan ishlov beriladi.<\/li>\n
    3. Mikroklimatning o'zgarishi:<\/strong> Qolgan ko'chatlar tuproq yuzasini quritish uchun kaltsiylangan daryo qumi yoki kul bilan sepilishi kerak.<\/li>\n
    4. Kimyoterapiya:<\/strong> Agar lezyon fokal bo'lsa, o'simlik to'qimasida patogenning rivojlanishini bostiradigan tizimli preparatlar (Previkur Energy) bilan sug'orish tavsiya etiladi.<\/li>\n<\/ol>\n

      \"Qora<\/p>\n

      Ko'chatlarni himoya qilish davolashga emas, balki qo'ziqorinlar uchun noqulay sharoitlar yaratishga asoslangan. Qishloq xo'jaligi texnologiyasining asosiy tamoyillari:<\/p>\n

        \n
      • Substrat tayyorlash:<\/strong> 2026-yilda nafaqat tuproqni isitish, balki ekishdan ikki hafta oldin unga foydali mikroflora (Trichodermin, Alirin, Gamair) bilan urug' sepish tavsiya etiladi. Bu patogenlar uchun joy bo'lmagan raqobat muhitini yaratadi.<\/li>\n
      • Drenaj va sug'orish:<\/strong> Stakanning pastki qismida suvning turg'un bo'lishidan saqlanish muvaffaqiyat kalitidir. Faqat pastki qismdan (laganda orqali) sug'orish tuproqning yuqori qatlamini quruq holda saqlaydi.<\/li>\n
      • Yorug'lik rejimi:<\/strong> Fitolampalar bilan qo'shimcha yoritish (12-14 soat) poyaning etiolatsiyasini (cho'zilishi) oldini oladi, bu esa to'qimalarni zichroq va qo'ziqorin gifalarining kirib kelishiga chidamli qiladi.<\/li>\n
      • Harorat stressi:<\/strong> To'satdan harorat o'zgarishi (kunduzgi haddan tashqari qizib ketish bilan kechadigan sovuq kechalar) ko'chatlarning immunitet tizimini zaiflashtiradi. Kunduzi barqaror 18-20\u00b0C va kechasi 15-16\u00b0C harorat ideal muvozanatdir.<\/li>\n<\/ul>\n

        Tez-tez so'raladigan savollar: Mutaxassislardan tez-tez so'raladigan savollarga javoblar<\/h2>\n

        Pishirish sodasi bilan kukun surtish yordam beradimi?<\/strong>
        Pishirish sodasi tuproqning pH qiymatini ishqoriy darajaga o'zgartiradi, bu esa ba'zi zamburug'larning rivojlanishini vaqtincha inhibe qiladi. Biroq, bu tizimli yechim emas, balki faqat qo'shimcha chora. Pishirish sodasining haddan tashqari dozasi ildiz kuyishiga olib kelishi mumkin.<\/p>\n

        Qora oyoq paydo bo'lsa, ko'chatlarni ko'chirib o'tkazishim kerakmi?<\/strong>
        Teshib tashlash oxirgi chora hisoblanadi. Agar o'simlik allaqachon kasallangan bo'lsa, siz infeksiyani vositalaringizga va yangi idishga yuqtirish xavfini tug'dirasiz. Nekrozga uchragan poyasi bo'lgan ko'chatni saqlab qolishga urinishdan ko'ra, kasal o'simlikni olib tashlash va guruhni ajratib qo'yish yaxshiroqdir.<\/p>\n

        Ildiz zonasini himoya qilish uchun qanday qumdan foydalanishim kerak?<\/strong>
        Faqat yuvilgan va pechda pishirilgan daryo qumidan foydalaning (150\u00b0C da kamida 30 daqiqa). Qum qutisidan olingan oddiy qum patogen sporalarini o'z ichiga oladi va vaziyatni yanada yomonlashtirishi mumkin.<\/p>","protected":false},"excerpt":{"rendered":"
