Ko'chat idishlari ustida sciaridlar deb nomlanuvchi mayda qora pashshalarning paydo bo'lishi noto'g'ri yetishtirish amaliyotidan dalolat beradi. Sciaridae oilasiga mansub bu hasharotlar botqoqlangan tuproqda faol ravishda ko'payib, yosh ko'chatlarning ildiz tizimiga xavf tug'diradi. Voyaga yetganlari deyarli zararsiz bo'lsa-da, ularning lichinkalari nozik ildiz to'qimalariga zarar etkazishi mumkin, bu esa o'simliklarning o'sishini to'xtatishi yoki nobud bo'lishiga olib keladi. Zararkunandalarni o'z vaqtida aniqlash va sug'orish rejimini sozlash ko'chatlarning sifatini saqlashning kalitidir.<\/p>\n

\"Ko'chatlardagi<\/p>\n

Skaridlarning biologik xususiyatlari<\/h2>\n

Voyaga yetgan hasharotlarning o'lchami 0,5 dan 2 mm gacha bo'lib, to'q tana rangi bilan ajralib turadi. Lycoriella, Sciara va Bradysia avlodlari vakillari ko'pincha uylarda uchraydi, ular tuxum qo'yish uchun nam substratlarni afzal ko'rishadi. Chig'anoqning hayot aylanishi tuproqdagi organik moddalar bilan chambarchas bog'liq.<\/p>\n

Urg'ochi tuproqning sirt qatlamida 250 tagacha tuxum qo'yadi, undan bir hafta ichida xarakterli qora boshli shaffof lichinkalar chiqadi. Yomg'ir chuvalchanglaridan farqli o'laroq, skiarid lichinkalari chirigan organik moddalar bilan oziqlanadi, ammo ozuqa yetishmasa, ular sog'lom ko'chat ildizlariga o'tadi.<\/p>\n

Ularning rivojlanishi uchun optimal sharoitlar tuproqning yuqori namligi va bakterial blyashka mavjudligini o'z ichiga oladi. Lichinkalar tez ko'payishi mumkin, shuning uchun hatto kattalarning kichik populyatsiyasi ham xonadagi barcha ko'chatlar uchun potentsial xavf tug'diradi.<\/p>\n

Ko'chatlar uchun tahdidni baholash<\/h2>\n

Asosiy zarar lichinkalar tomonidan yetkaziladi, ular oziqlanish paytida ildiz tuklari va yosh ildizlarni kemiradi. Yangi chiqqan ko'chatlar uchun ildiz tizimiga zarar yetkazish ko'pincha halokatli bo'ladi, chunki o'simlik namlik va ozuqa moddalarini samarali singdirish qobiliyatini yo'qotadi.<\/p>\n

Lichinka<\/td>\nYuqori<\/td>\nIldiz tizimi, organik moddalar<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Shuni ta'kidlash kerakki, to'yimli, gumusga boy tuproqda lichinkalar ildizlarga tegmasligi mumkin, organik substratni afzal ko'rishadi. Biroq, steril yoki yomon tuproq aralashmalarida ko'chatlarga zarar yetkazish xavfi sezilarli darajada oshadi. Ildizlarga har qanday mexanik shikastlanish patogen zamburug'larning kirib borishiga yo'l ochadi.<\/p>\n

Infektsiya tashxisi<\/h2>\n

Zararkunandaning birinchi belgisi - bu idishga yengil tegilganda tuproq yuzasi ustida hasharotlar to'dasi paydo bo'lishi. Bu ko'payish sikli allaqachon boshlanganini va tuproqda ko'p sonli lichinkalar mavjudligini ko'rsatadi.<\/p>\n

\"Kastryulkada<\/p>\n

    \n
  • O'simliklar yaqinidagi havoda kattalarning mavjudligi.<\/li>\n
  • Tuproq yuzasida shilimshiq izlar.<\/li>\n
  • Tuproqni transplantatsiya qilish yoki yumshatish paytida lichinkalarni vizual aniqlash.<\/li>\n
  • Yetarli sug'orish bilan ko'chatlarning tushkun holati.<\/li>\n<\/ul>\n

    Ommaviy ko'payish sabablari<\/h2>\n

    Asosiy omil substratdagi ortiqcha namlik bo'lib, u lichinkalar uchun ko'payish joyini yaratadi. Zararkunandalar ko'pincha kvartiralarga sifatsiz do'kondan sotib olingan tuproq yoki hasharot tuxumlari bo'lgan sterilizatsiya qilinmagan bog 'tuprog'i orqali kiradi.<\/p>\n

    Idishning dizayni ham rol o'ynaydi: drenaj teshiklarining yo'qligi yoki haddan tashqari chuqur stakanlar havo almashinuvining to'g'ri bo'lishiga to'sqinlik qiladi. Natijada, tuproqning pastki qatlamlari kislotali bo'lib, sciaridlarning o'sishi uchun ideal sharoitlarni yaratadi.<\/p>\n

    Choy barglari yoki po'stlog'i damlamalari kabi organik o'g'itlardan foydalanish populyatsiyaning tez o'sishini rag'batlantiradi. Nam organik moddalar lichinkalar uchun qo'shimcha oziq-ovqat manbai bo'lib xizmat qiladi va ularning kattalarga aylanishini tezlashtiradi.<\/p>\n

    Xalq vositalaridan foydalangan holda nazorat qilish usullari<\/h2>\n

    Agar hasharotlar populyatsiyasi oz bo'lsa, yumshoqroq choralar yetarli bo'lishi mumkin. Xalq vositalaridan muntazam foydalanishni talab qilishini va ko'pincha faqat birgalikda qo'llanilganda samara berishini tushunish muhimdir.<\/p>\n

    \"Midjlarga<\/p>\n

      \n
    • Voyaga yetgan namunalarni tutish uchun sariq yopishqoq tuzoqlarni o'rnatish.<\/li>\n
    • Tuproq yuzasini quruq qum yoki yog'och kul bilan 2 mm gacha bo'lgan qatlamda mulchalash.<\/li>\n
    • Voyaga yetgan pashshalarni haydash uchun dolchin yoki chinnigullar kabi ziravorlardan foydalanish.<\/li>\n
    • Lichinkalar to'plangan substratning yuqori qatlamini quritish uchun sug'orishni cheklang.<\/li>\n<\/ul>\n

      Insektitsidlardan foydalanish<\/h2>\n

      Zararkunandalar ko'payib ketganda, xalq davolari samarasiz, chunki ular tuproqqa chuqur ko'milgan lichinkalarga ta'sir qilmaydi. Bunday hollarda maxsus tuproqqa ta'sir qiluvchi insektitsidlar qo'llaniladi.<\/p>\n

      \"Ko'chatlarni<\/p>\n

        \n
      • Tiametoksamga asoslangan preparatlar (10 litr suvga 1 ml suyultirish) 28 kungacha keng qamrovli himoyani ta'minlaydi.<\/li>\n
      • Lichinkalarni yo'q qilish uchun tuproqning yuqori qatlamiga 1-2 sm chuqurlikka singdirilgan granulali diazinon asosidagi mahsulotlar.<\/li>\n<\/ul>\n

        Profilaktik choralar<\/h2>\n
          \n
        1. Tuproq aralashmasini 70 \u00b0C da 30 daqiqa davomida kalsinatsiya qilish orqali majburiy dezinfeksiya qilish.<\/li>\n
        2. Ko'chatlar uchun har bir idishda yuqori sifatli drenaj qatlamini tashkil qilish.<\/li>\n
        3. Sug'orish rejimini nazorat qilish: sug'orishlar oralig'ida tuproqning yuqori qatlamini quritish.<\/li>\n
        4. O'simlik qoldiqlarini o'z vaqtida olib tashlash va organik "uy qurilishi" o'g'itlaridan foydalanishdan bosh tortish.<\/li>\n
        5. Aeratsiyani yaxshilash va namlikning turg'unligini oldini olish uchun tuproqni muntazam ravishda yumshatish.<\/li>\n<\/ol>\n

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

          Chivinlar quruq tuproqda yashay oladimi?<\/h3>\n

          Sciarid lichinkalari substratning qurib ketishiga juda sezgir va namlik bo'lmaganda o'ladi, shuning uchun sug'orishni nazorat qilish oldini olishning asosiy usuli hisoblanadi.<\/p>\n

          Agar chivinlarni ko'rsam, tuproqni almashtirishim kerakmi?<\/h3>\n

          Tuproqni butunlay almashtirish o'ta chora hisoblanadi, chunki bu ildizlarga zarar etkazishi mumkin. Odatda, tuproqning qurib qolishiga yo'l qo'yish va insektitsidlarni qo'llash kifoya.<\/p>\n

          Yerga tiqilib qolgan gugurt yordam beradimi?<\/h3>\n

          Bu usul samarasiz deb hisoblanadi va qozonning chuqur qismida joylashgan lichinkalardan himoya qilmaydi.<\/p>\n

          Kimyoviy moddalar qanchalik tez ta'sir qiladi?<\/h3>\n

          Donador mahsulotlardan foydalanganda, lichinkalarning o'limi tuproqqa qo'llanilgandan 3-5 kun o'tgach boshlanadi.<\/p>","protected":false},"excerpt":{"rendered":"
