Omela daraxt shoxlariga joylashib, ularning sharbati bilan oziqlanadigan doim yashil yarim parazit buta hisoblanadi. Bu o'simlik bog' uchastkasiga jiddiy zarar yetkazishi, mevali hosilni asta-sekin kamaytirib, yo'q qilishi mumkin. Omela hayot aylanishini tushunish bog'bonlarga muammoni erta aniqlash va bog'larini himoya qilish choralarini ko'rish imkonini beradi. Urug'lar asosan qushlar tomonidan tarqaladi, bu esa zararkunandaning ko'rinishini oldindan aytib bo'lmaydi.<\/p>\n

Omelaning biologik xususiyatlari va turlari<\/h2>\n

Omela Strabiscaphia oilasiga mansub bo'lib, yarim parazit poyaga ega bo'lib, terisimon barglarga ega. Mo''tadil iqlim sharoitida eng keng tarqalgan omela oq omela bo'lib, u o'ziga xos och rangli mevalarni beradi. O'simlik sharsimon shaklga va soxta dixotomiyali poyalarga ega bo'lib, bu unga o'z daraxtining soyaboniga samarali yopishib olish imkonini beradi.<\/p>\n

Uning oziqlanish mexanizmi daraxtning yog'ochiga chuqur kirib boradigan so'rg'ichlarga tayanadi. Omela o'zining o'sishi uchun zarur bo'lgan suv va minerallarni o'ziga tortadi, bu esa daraxtning o'zida ozuqa moddalarining yetishmasligiga olib keladi. Agar nazorat qilinmasa, buta diametri 125 sm gacha o'sishi mumkin, bu esa o'ziga biriktirilgan shoxlarni butunlay bo'g'ib qo'yadi.<\/p>\n

Omela o'simligini e'tiborsiz qoldirishning oqibatlari zararlangan joylarning asta-sekin qurib ketishi va hosildorlikning pasayishini o'z ichiga oladi. Mo''tadil iqlim sharoitida, qishda, barglarning yo'qligi zararkunandani ko'proq ko'rinadigan qilib qo'yganda, olma va nok daraxtlarining tojlarini tekshirish muhimdir. Omela o'simligi yetuk, sog'lom daraxtga zarar yetkazmaydi deb o'ylash xato.<\/p>\n

\"Mistletoe<\/p>\n

Urug'larning infektsiyasi va unib chiqishi jarayoni<\/h2>\n

Omela urug'lari visen deb ataladigan yopishqoq modda bilan o'ralgan bo'lib, bu ularning daraxt po'stlog'iga mahkam yopishishiga imkon beradi. Rezavorlar bilan oziqlanadigan qushlar urug'larni yangi shoxlarga olib boradi va bu parazitning keng tarqalishini ta'minlaydi. Unib chiqish bahorda, ildiz po'stloq yuzasiga mahkamlash uchun appressorium deb ataladigan maxsus plastinka hosil qilganda boshlanadi.<\/p>\n

Shoxga kirish gaustorium hosil bo'lishi orqali sodir bo'ladi, u yog'ochga o'sadi. Keyingi yillarda omela po'stlog'i orqali tarqaladigan va yangi oziqlanish joylarini egallaydigan rizoidlarni rivojlantiradi. Bu parazitga, hatto butaning tashqi qismi kichik bo'lib ko'rinsa ham, daraxt resurslariga doimiy kirish imkonini beradi.<\/p>\n

Ko'paytirish paytida urug'larni noto'g'ri joylashtirish yoki yosh ko'chatlarni kuzatmaslik parazitning tez o'sishiga olib keladi. Muvaffaqiyatli o'sishi uchun \u00f6kseotu o'rtacha namlik va daraxtning qon tomir to'qimalariga kirishni talab qiladi. Keng tarqalgan xato - bu dastlab po'stlog'i ostida yashiringan \u00f6kseotu ildiz tizimining rivojlanish tezligini kam baholashdir.<\/p>\n

Omela mevali daraxtlarga ta'siri<\/h2>\n

Mevali daraxtlarning omela bilan zararlanishi mezbon o'simlikning energiya zaxiralarining asta-sekin kamayib ketishiga olib keladi. Olma va nok daraxtlari gullashning pasayishini boshdan kechiradi, keyin esa mineral ozuqalar yetishmasligi tufayli meva berish butunlay to'xtaydi. Og'ir holatlarda daraxt charchoq va gustoriya orqali kirib boradigan ikkilamchi infeksiyalardan nobud bo'lishi mumkin.<\/p>\n

\"\"<\/p>\n

Omela gullab-yashnashi sharoitlari daraxt immunitetining zaiflashishi va po'stlog'ining shikastlanishi bilan bog'liq. Joriy mavsumda omela gullab-yashnashining dastlabki belgilari kuzatiladigan shoxlarni kesish tavsiya etiladi. Agar parazit erta olib tashlanmasa, uning ildiz tizimi juda kengayib, xavfsiz olib tashlashning iloji bo'lmaydi.<\/p>\n

Amaliy tavsiya - zararlangan shoxni butunlay olib tashlash, kirish joyidan 10-15 santimetr pastda sog'lom yog'ochni olib tashlash. Daraxt ichida \u00f6kseotu parchalarini qoldirmang, chunki ular yangi kurtaklarga aylanishi mumkin. Bu eng samarali nazorat usuli, chunki \u00f6kseotuni tanlab o'ldirish uchun kimyoviy moddalar yo'q.<\/p>\n

Profilaktik choralar va harakatlar rejasi<\/h2>\n

Bog'ingizda omela tarqalishining oldini olish uchun siz aniq harakatlar algoritmiga amal qilishingiz kerak:<\/p>\n

    \n
  1. Kech kuzda va qishda daraxt tojlarini muntazam ravishda tekshirib turing.<\/li>\n
  2. Buta meva berishni boshlashdan oldin omlet shoxlarini kesib oling.<\/li>\n
  3. Infektsiyalangan daraxt bilan har bir manipulyatsiyadan keyin asboblarni dezinfektsiya qiling.<\/li>\n
  4. To'g'ri sug'orish va o'g'itlash orqali sog'lom daraxtlarni saqlang.<\/li>\n
  5. Quruq shoxlarni darhol olib tashlang, chunki ular ko'pincha parazit uchun kirish joyiga aylanadi.<\/li>\n<\/ol>\n

    \"\"<\/p>\n

      \n
    • Qushlarni jalb qilmaslik uchun daraxtda omlet mevalarini qoldirmang.<\/li>\n
    • Omela o'simligini nazorat qilish uchun begona o'tlarga qarshi mo'ljallangan gerbitsidlardan foydalanmang.<\/li>\n
    • Yosh ko'chatlardagi hatto kichik butalarning ko'rinishini ham e'tiborsiz qoldirmang.<\/li>\n
    • Tojning zich bo'lishiga yo'l qo'ymang, bu urug'larni unib chiqish uchun qulay mikroiqlim yaratadi.<\/li>\n
    • Parazitni o'zi jismonan olib tashlamasdan, daraxtni xalq usullari bilan davolashga urinmang.<\/li>\n<\/ul>\n

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

      Daraxtni shoxini olib tashlamasdan davolash mumkinmi?<\/h3>\n

      Afsuski, shoxning bir qismini olib tashlamasdan samarali davolash mumkin emas, chunki omela ildiz tizimi daraxtga chuqur kirib boradi. Yashil kurtaklarni shunchaki sindirib tashlashga urinish po'stlog'i ostidagi rizoidlarning omon qolishiga va yangi kurtaklar paydo bo'lishiga olib keladi. Daraxtni saqlab qolishning yagona yo'li - zararlangan qismni to'liq olib tashlash.<\/p>\n

      Omela odamlar uchun xavflimi?<\/h3>\n

      Omela zaharli o'simlik, shuning uchun u bilan har qanday aloqa ehtiyotkorlikni talab qiladi. Rezavorlarni yoki butaning qismlarini iste'mol qilish taqiqlanadi, chunki bu jiddiy zaharlanishga olib kelishi mumkin. O'simlik moddalari, ayniqsa, homilador ayollar va bolalar uchun xavflidir.<\/p>\n

      Nima uchun \u00f6kseotu bunchalik tez tarqaladi?<\/h3>\n

      Asosiy sabab qushlarning urug'larni samarali tarqatish strategiyasi va rezavorlarning juda yopishqoqligidir. Yopishqoq viskens urug'ning qush qo'ngan har qanday shoxga mahkam yopishishini ta'minlaydi. Bu zararkunandalarga bitta bog' yoki hatto butun mintaqadagi daraxtlar orasida osongina harakatlanish imkonini beradi.<\/p>","protected":false},"excerpt":{"rendered":"
