Sog'lom pomidorlar ildizlari, barglari va mevalarining holatiga doimiy e'tibor berishni talab qiladi. Ehtiyotkorlik bilan parvarish qilinsa ham, patogenlar bog'ga kirib, tezda tarqalishi mumkin. Tasdiqlangan qishloq xo'jaligi amaliyotlaridan foydalanish va o'z vaqtida tashxis qo'yish o'simliklarning mahsuldorligini saqlashga yordam beradi. Infektsiya mexanizmlarini tushunish bog'bonlarga proaktiv harakat qilish, hosil yo'qotishlarini minimallashtirish imkonini beradi. Samarali himoya profilaktika va ma'lum alomatlarga asoslangan pestitsidlarni maqsadli qo'llashning kombinatsiyasiga asoslangan.<\/p>\n

\"Pomidor<\/p>\n

Mevalarning bakterial dog'i<\/h2>\n

Pseudomonas syringae bakteriyalarining rivojlanishiga salqin ob-havo va sepishdan kelib chiqadigan ortiqcha namlik yordam beradi. Meva yuzasida diametri 1 mm gacha bo'lgan kichik dog'lar paydo bo'ladi, ular biroz cho'kib ketgan bo'lishi mumkin. Pishmagan pomidorlarda jarohatlar atrofida ko'rinadigan yashil chegara, pishganlarida esa sariq chegara mavjud.<\/p>\n

Infektsiya ko'pincha ifloslangan urug'lardan foydalanish yoki noto'g'ri sug'orish natijasida yuzaga keladi. Mo''tadil iqlim sharoitida tuproqning pH qiymatini 6,0\u20136,8 oralig'ida saqlash muhimdir. Patogen rivojlanishi uchun optimal harorat 18\u201324\u00b0C dir.<\/p>\n

Sanitariya me'yorlariga e'tibor bermaslik bozorda sotiladigan mevalarning keng miqyosda yo'qolishiga olib keladi. Bog'bonlarning asosiy xatosi barglarni sug'orishdir, bu esa bakteriyalar uchun ideal muhit yaratadi. Kasal o'simlik bilan har bir aloqadan keyin tomchilatib sug'orishdan foydalaning va vositalarni dezinfektsiya qiling.<\/p>\n

\"Mevalarning<\/p>\n

Phytophthora rot<\/h2>\n

Phytophthora infestans oomitseti iliq kunlar salqin tunlar bilan almashinib turganda yaxshi rivojlanadi. Patogen avval pastki barglarga hujum qiladi, keyin tezda mevaga tarqalib, konsentrik halqali kulrang-jigarrang dog'lar hosil qiladi. Yuqori namlik ostida dog'lar yengil sporalar bilan qoplanadi.<\/p>\n

Kasallikning oldini olish uchun issiqxonada yaxshi aeratsiyani ta'minlash va begona o'tlarni o'z vaqtida olib tashlash muhimdir. Mo''tadil iqlim sharoitida kechki chirigan o'simta ko'pincha iyul va avgust oylarida haroratning keskin o'zgarishi paytida paydo bo'ladi. Ildizlar atrofida suvning turg'unligini oldini olish uchun tuproq bo'shashgan va yaxshi drenajlangan bo'lishi kerak.<\/p>\n

Davolashning yo'qligi bir necha kun ichida hosilning to'liq nobud bo'lishiga olib keladi. Keng tarqalgan xato - zich ekish, bu esa havo aylanishiga to'sqinlik qiladi. Pastki qavatlarni muntazam ravishda tekshirib turing va yerga tegib turgan barglarni olib tashlang.<\/p>\n

Pomidor antraknozi<\/h2>\n

\"Antraknoz\"<\/p>\n

Colletotrichum turkumidagi zamburug'lar mevalarda chuqur dog'lar hosil qiladi, ular oxir-oqibat sarg'ish-jigarrang rangga kiradi. Kasallik iliq va yomg'irli ob-havoda tez tarqaladi, ham yashil, ham pishgan pomidorlarga ta'sir qiladi. Zamburug' sporalari tuproqda qulay sharoitlarni kutib, yillar davomida yashashi mumkin.<\/p>\n

Infeksiya shamol va yomg'ir suvlari oqimi orqali yuqadi, shuning uchun mevalarga sachrashining oldini olish uchun tuproqni mulchalash muhimdir. Tuproq yaxshi drenajlangan bo'lishi kerak va zamburug'lar rivojlanishi uchun optimal harorat 20\u201328\u00b0C ni tashkil qiladi. Noto'g'ri almashlab ekish antraknoz avj olish xavfini sezilarli darajada oshiradi.<\/p>\n

Kontakt fungitsidlar bilan profilaktik purkashsiz, mevalar shilimshiq modda bilan qoplanadi va yeyilmaydigan holga keladi. Infektsiyaning asosiy manbasini yo'q qilish uchun urug'larni ekishdan oldin dezinfektsiya qilishni unutmang.<\/p>\n

Gullash oxiridagi chirish<\/h2>\n

\"Pomidor<\/p>\n

Gullash oxiridagi chirish kuchli kaltsiy yetishmovchiligining natijasidir, bu esa nomutanosib sug'orish bilan kuchayadi. Mevaning yuqori qismida cho'kib ketgan dog' hosil bo'ladi, u vaqt o'tishi bilan qorayadi va chirishi mumkin. Ko'pincha faol o'sish bosqichidagi mevalar ta'sirlanadi.<\/p>\n

Muammo tuproq namligi keskin o'zgarib, o'simlikning kaltsiyni mevaga tashishiga to'sqinlik qilganda yuzaga keladi. Tuproq namligini 70-80\u00b0C da saqlash va ortiqcha azot qo'llamaslik tavsiya etiladi. Mo''tadil iqlim sharoitida faol o'sish davrida tuproq qurib ketmasligiga ishonch hosil qilish muhimdir.<\/p>\n

Mal\u00e7lama va noto'g'ri sug'orish bu muammoning asosiy sabablari hisoblanadi. Buning oqibatlari mevalarning bozor ko'rinishini yo'qotishi va mevalarning muddatidan oldin tushishiga olib keladi. Amaliy maslahat: kaltsiy nitratining yetishmasligining birinchi belgisida qo'llang.<\/p>\n

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

Gul uchida chirishi bo'lgan mevalarni iste'mol qilish xavfsizmi?<\/h3>\n

Ha, agar mevaning faqat bir qismi shikastlangan bo'lsa, uni kesib tashlash mumkin va qolgan qismini qayta ishlash uchun ishlatish mumkin. Biroq, bunday pomidorlar uzoq muddatli saqlash uchun mos emas. Agar chirish ikkilamchi infeksiya bilan birga bo'lsa, mevani tashlab yuborish yaxshidir.<\/p>\n

Asboblarni qanchalik tez-tez dezinfektsiya qilish kerak?<\/h3>\n

Agar kasallikka shubha qilinsa, har bir butada har bir ishdan keyin asboblarni spirtli eritma yoki kaliy permanganatning kuchsiz eritmasi bilan artib tashlash kerak. Bu bog' bo'ylab sporalar va bakteriyalarning tarqalishini oldini oladi. Toza asboblar sog'lom bog'ning asosidir.<\/p>\n

Xalq usullari chiriganlarga qarshi kurashda yordam beradimi?<\/h3>\n

Zardob yoki yodga asoslangan biologik preparatlar va xalq davolanish usullari faqat dastlabki bosqichlarda yoki profilaktika chorasi sifatida samarali bo'ladi. Ular keng tarqalgan zararkunandalar bo'lgan taqdirda samarali bo'lmaydi. Har doim qishloq xo'jaligi amaliyotlarini tasdiqlangan biofungitsidlar bilan birlashtiring.<\/p>","protected":false},"excerpt":{"rendered":"
