Bodring barglarining sarg'ayishi biologik jarayonlardagi buzilish yoki tashqi stressni anglatadi. Muammo tabiiy qarish, qishloq xo'jaligi amaliyotidagi jiddiy xatolar, infektsiyalar yoki zararkunandalar tufayli yuzaga kelishi mumkin. Erta tashxis qo'yish zararning tarqalishini to'xtatishga va meva berish salohiyatini saqlab qolishga yordam beradi. Quyida biz barg rangiga ta'sir qiluvchi asosiy omillar va ularni qanday hal qilish haqida gaplashamiz.<\/p>\n

\"Bodring<\/p>\n

O'simliklarning fiziologik qarishi<\/h2>\n

Bodringlarning pastki barglari hayot aylanishining oxiriga yetganda tabiiy ravishda sarg'ayadi. Fotosintezning pasayishi barg pichoqlarining avval oqarib ketishiga, keyin sarg'ayishiga va asta-sekin qurib qolishiga olib keladi. Bu yosh kurtaklarga ta'sir qilmasa, hech qanday aralashuvni talab qilmaydigan normal jarayon.<\/p>\n

Qarishni kasallikdan ajratish oson: zararlanish faqat tokning tagidan boshlanadi va asta-sekin yuqoriga qarab o'sadi. Boshqa tomondan, patologiya belgilari ko'pincha tasodifiy yoki tepada paydo bo'ladi. Chirish xavfini oldini olish uchun eski barglarni ehtiyotkorlik bilan olib tashlash tavsiya etiladi.<\/p>\n

Muntazam sanitariya Azizillo zich ekilgan daraxtlarda qo'ziqorin infektsiyalari rivojlanishining oldini oladi. Tez quriydigan mayda dog'larni qoldiring. Kesilgan uchlarida chirishni oldini olish uchun yomg'irli ob-havoda Azizillo qilmang.<\/p>\n

\"Bodringning<\/p>\n

Yorug'lik rejimini sozlash<\/h2>\n

Bodring normal metabolizmni saqlab turish uchun kuniga kamida 6-8 soat davomida kuchli yorug'likka muhtoj. Soyada o'simlik cho'zilib ketadi va barglari och sariq rangga aylanib, boy yashil rangini yo'qotadi. Bog' uchun eng maqbul joy - bu binolar yoki daraxtlardan uzoq vaqt soya tushmaydigan ochiq maydon.<\/p>\n

Haddan tashqari to'g'ridan-to'g'ri quyosh nuri ta'siri ham xavfli, ayniqsa 29\u00b0C (84\u00b0F) dan yuqori haroratlarda. Nurlar quyoshda kuyishga olib keladi, bu esa jigarrang, quruq qirralar va keyinchalik to'qimalarning o'limi bilan namoyon bo'ladi. Shikastlangan barglar mevani himoya qilishni to'xtatadi, bu uning ta'mini va umumiy hosildorligini pasaytiradi.<\/p>\n

Haddan tashqari issiq davrlarda, 30\u201340% soya koeffitsientiga ega soyabon to'ridan foydalaning. Bu barg yuzasi haroratini pasaytiradi va suvsizlanishning oldini oladi. Quyosh yonishi xavfi eng yuqori bo'lgan tushdan keyin butalarni kuzatib boring.<\/p>\n

\"Bodring<\/p>\n

Sug'orish va namlikni optimallashtirish<\/h2>\n

Bodring namlikka yuqori talab tufayli suv muvozanatiga sezgir. Haddan tashqari sug'orish kislorodning ildizlarga yetib borishiga to'sqinlik qiladi va bu ildiz chirishiga olib keladi. Bu o'zini yuqori barglardan boshlab so'lib, sarg'ayish bilan namoyon qiladi, bu esa tezda butun o'simlikning o'limiga olib keladi.<\/p>\n

Sug'orishning yetarli emasligi stressni keltirib chiqaradi, bu esa barglarning jingalaklanishiga, chekkalari sarg'ayishiga va qurib qolishiga olib keladi. 96% o'simligi suvdan iborat bo'lgani uchun, hatto tuproqning qisqa vaqt ichida qurib qolishi ham juda muhimdir. "Barmoq sinovi" usulidan foydalaning: agar tuproq 5-7 sm chuqurlikda quruq bo'lsa, darhol sug'orish kerak.<\/p>\n

Ildiz zonasida suvning turg'un bo'lishining oldini olish uchun yaxshi drenajni ta'minlang. Quyoshli soatlarda barglarga tomchilab tushmasligi uchun ildizlarga sug'oring. Tuproqni mulchalash namlikni uzoqroq saqlashga va bug'lanishni kamaytirishga yordam beradi.<\/p>\n

\"Bodringlarni<\/p>\n

Oziq moddalar balansi<\/h2>\n

Azot yetishmasligi sarg'ayishning eng keng tarqalgan sababi bo'lib, butun barg poyasining bir xil rangsizlanishi sifatida namoyon bo'ladi. Muammo eski barglardan boshlanadi, chunki o'simlik azotni yosh kurtaklarga qayta taqsimlaydi. Magniy yetishmasligi venalararo xlorozga olib keladi: tomirlar yashil bo'lib qoladi, lekin ular orasidagi bo'shliq sarg'ayadi.<\/p>\n

Kaliy yoki boshqa elementlarning ortiqcha miqdori magniy va temirning so'rilishini to'sib qo'yishi va soxta tanqislikni keltirib chiqarishi mumkin. Buning oldini olish uchun mikroelementlar bilan muvozanatli, murakkab o'g'itlardan foydalaning. O'g'it qo'llashda kimyoviy ildiz kuyishining oldini olish uchun ishlab chiqaruvchi tomonidan tavsiya etilgan dozaga qat'iy rioya qiling.<\/p>\n\n\n\n\n\n\n

\"Bodringda<\/p>\n

Zararkunandalar va yuqumli kasalliklar<\/h2>\n

Shira va o'rgimchak oqadilar sarg'ayishga olib keladigan asosiy zararkunandalardir. Shiralar sharbatni so'rib olib, yopishqoq qoldiq qoldiradi, o'rgimchak oqadilar esa sariq dog'larga aylanadigan mayda oq nuqtalarni qoldiradi. Agar zararkunandalar aniqlansa, barglarning pastki qismiga sovunli eritmalar yoki biologik ishlov berish vositalarini qo'llang.<\/p>\n

Kukunli chiriyotgan kabi qo'ziqorin kasalliklari oq qoplama sifatida ko'rinadi, mayin chiriyotgan esa vaqt o'tishi bilan qorayadigan sariq dog'lar sifatida ko'rinadi. Bodring mozaikasi virusi o'ziga xos dog'li naqsh va barg deformatsiyasini keltirib chiqaradi. Bu viruslar uchun hech qanday davolash yo'q, shuning uchun zararlangan o'simliklar darhol olib tashlanishi kerak.<\/p>\n

    \n
  • Barglarning pastki qismini muntazam ravishda tekshirib turing.<\/li>\n
  • Qovoqdan keyin bodring ekmaslik orqali almashlab ekishni mashq qiling.<\/li>\n
  • Viruslarni saqlashi mumkin bo'lgan begona o'tlarni olib tashlang.<\/li>\n<\/ul>\n

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

    Mozaik virusi bilan o'simlikni saqlab qolish mumkinmi?<\/h3>\n

    Yo'q, bodring virusli kasalliklari davolab bo'lmaydi. Sog'lom o'simliklarning yuqishini oldini olish uchun zararlangan o'simliklarni olib tashlash va yoqish kerak.<\/p>\n

    Tuproq namligini qanchalik tez-tez tekshirish kerak?<\/h3>\n

    Issiq davrlarda tuproqni har kuni tekshirib turing. Bulutli ob-havoda har 2-3 kunda tuproqni tekshirish kifoya.<\/p>\n

    Xalq tabobati shiralariga qarshi kurashda yordam beradimi?<\/h3>\n

    Dastlabki bosqichlarda kir sovuni yoki kul-sovun damlamalari samarali bo'ladi. Og'ir zararkunandalar uchun maxsus bioinsektitsidlardan foydalanish yaxshidir.<\/p>","protected":false},"excerpt":{"rendered":"
