Yopiq atirguldagi sarg'aygan barglar biologik jarayonlarning buzilishi yoki tashqi stressning belgisi bo'lib, o'simlik fotosintezni sekinlashtirish orqali javob beradi. O'sish siklining oxirida eski pastki barglarning asta-sekin so'lib ketishi bilan birga keladigan tabiiy qarishdan farqli o'laroq, patologik sarg'ayish tezkor tashxis qo'yishni talab qiladi. Agar rang o'zgarishi yosh kurtaklarga, kurtaklarga ta'sir qilsa yoki butun buta bo'ylab tarqalsa, o'sish sharoitlarini tahlil qilish kerak, chunki ular atirgulning tashqi omillarga chidamliligini aniqlaydi.<\/p>\n

Mikroiqlimning atirgullarning holatiga ta'siri<\/h2>\n

Atirgullar harorat va namlikning keskin o'zgarishiga juda sezgir. Turar-joy sharoitida, ayniqsa isitish mavsumida, o'simlik ko'pincha qizib ketish va quruq havodan aziyat chekadi. Bu turgorning yo'qolishiga olib keladi: barglar burishadi, mo'rtlashadi va sarg'ish tus oladi. Qorong'ular qo'shimcha stress omili bo'lib, zarba reaktsiyasini va barglarning katta miqdorda tushishini keltirib chiqaradi.<\/p>\n

Oziq moddalar yetishmasligi va sug'orishdagi nosozliklar<\/h2>\n

O'simliklarning oziqlanishi barglarning pigmentatsiyasiga bevosita ta'sir qiladi. Asosiy elementlarning yetishmasligi xlorofill sintezini sekinlashtiradi, bu esa vizual ravishda xloroz sifatida namoyon bo'ladi.<\/p>\n\n\n\n\n\n\n\n
Element<\/td>\nKamchilikning xarakterli belgilari<\/td>\n<\/tr>\n
Azot<\/td>\nBarg pichog'ining rangparligi, yosh barglarning ezilishi<\/td>\n<\/tr>\n
Magniy<\/td>\nYashil markaziy tomirni saqlab turganda barg qirralarining sarg'ayishi<\/td>\n<\/tr>\n
Temir<\/td>\nYosh barglarda venalararo xloroz<\/td>\n<\/tr>\n
Kaliy<\/td>\nChegara kuyishi, uchlarining sarg'ayishi, qora dog'lar paydo bo'lishi<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Sug'orish ikkinchi muhim omil hisoblanadi. Idishdagi ortiqcha namlik ildizlarni kisloroddan mahrum qiladi, bu ularning chirishiga olib keladi, bu esa darhol tojga ta'sir qiladi - barglar yumshoq bo'lib sarg'ayadi. Boshqa tomondan, namlikning yetarli emasligi to'qimalarning qurishiga, elastiklikning yo'qolishiga va kurtaklarning mo'rtlashishiga olib keladi.<\/p>\n

\"Atirgullarda<\/p>\n

Biologik tahdidlar: zararkunandalar va kasalliklar<\/h2>\n

Zararkunandalar keltirib chiqaradigan sarg'ayish ko'pincha mikroskopik dog'lar paydo bo'lishi bilan boshlanadi, ular oxir-oqibat kattaroq joylarga birlashadi. Yopiq atirgullarning keng tarqalgan zararkunandalariga quyidagilar kiradi:<\/p>\n

    \n
  • O'rgimchak oqadilar - bargning orqa tomonida ingichka to'r va kichik yorug'lik nuqtalarini qoldiradi.<\/li>\n
  • Shira o'simtalari yosh kurtaklar va kurtaklarga diqqatni jamlab, sharbatini so'rib oladi.<\/li>\n
  • Qalin hasharotlar poyalar va petiolesda zich jigarrang blyashka shaklida ko'rinadi.<\/li>\n<\/ul>\n

    Zararkunandalarga qarshi kurashish uchun tizimli yondashuvni qo'llash kerak: o'simliklarni izolyatsiya qilish, parazitlarni mexanik ravishda yo'q qilish va o'simlik to'qimalariga zarar bermasdan hasharotlarning hayot aylanishini buzadigan ixtisoslashgan vositalar bilan davolash.<\/p>\n

    Profilaktik choralar<\/h2>\n

    Kelajakda barglarning sarg'ayishini oldini olish uchun qat'iy parvarish algoritmiga rioya qilish tavsiya etiladi:<\/p>\n

      \n
    1. To'satdan tebranishlardan qochib, haroratni 18-25\u00b0C oralig'ida saqlang.<\/li>\n
    2. Tabiiy yorug'lik yetarli bo'lmasa, fitolampalardan foydalanib, kamida 8-10 soat kunduzgi yorug'likni ta'minlang.<\/li>\n
    3. O'simlikni faqat tuproqning yuqori 2-3 sm qatlami quriganidan keyin sug'oring.<\/li>\n
    4. Transplantatsiya usuli yordamida faqat uyqu davrida - qish oxirida yoki bahorning boshida transplantatsiya qiling.<\/li>\n<\/ol>\n
