Piyoz barglarining sarg'ayishi fiziologik muammolar yoki patogen hujumining belgisi bo'lib, darhol aralashuvni talab qiladi. Faqatgina istisno - bu piyozning pishib yetilish davrida, ya'ni ozuqa piyozchaga o'tkazilganda barglarning tabiiy so'lib qolishi. Muammoni e'tiborsiz qoldirish hosilning yo'qolishiga olib keladi, shuning uchun qishloq xo'jaligidagi xatolardan tortib hasharotlar faolligigacha bo'lgan sababni o'z vaqtida aniqlash muhimdir. To'shaklarni o'z vaqtida tekshirish sizga hosilingizning ko'p qismini tejash va infektsiyalar tarqalishining oldini olish imkonini beradi.<\/p>\n

Piyoz patlarining sarg'ayishining oldini olish<\/h2>\n

Piyozning sog'lig'i to'g'ridan-to'g'ri tuproqni to'g'ri tayyorlash va asosiy qishloq xo'jaligi amaliyotlariga rioya qilishga bog'liq. Ekin tuproq tuzilishiga talabchan, 6,5\u20137,5 neytral pH ni afzal ko'radi va turg'un suvga toqat qilmaydi. Yetarli yorug'lik bilan ta'minlash juda muhim, chunki soyali joylarda qo'ziqorin kasalliklari xavfi sezilarli darajada oshadi.<\/p>\n

Ekin almashlab ekish himoya asosidir; piyoz kamida to'rt yil davomida asl joyiga qaytarilmasligi kerak. Tuproqni belkurak pichog'i bilan chuqur qazish va tuproqni ag'darish zararkunandalarning qishlash bosqichlarini yo'q qilishga yordam beradi. O'simliklarni muntazam tekshirish sizga zararlanishning dastlabki belgilarini erta aniqlash va kasal o'simliklarni ular zararlanish manbaiga aylanishidan oldin olib tashlash imkonini beradi.<\/p>\n

Kam yoki ortiqcha sug'orish ildiz tizimiga bir xil darajada zararli. Mo''tadil iqlim sharoitida piyoz barqaror namlikni talab qiladi, ammo suv bosishidan saqlaning. Agar bu shartlar bajarilmasa, o'simlik zaiflashadi va bu uni kasalliklar va zararkunandalarga moyil qiladi.<\/p>\n

Zararkunandalar sarg'ayish sababi sifatida<\/h2>\n

Piyoz to'shagining so'lib qolishining asosiy sababi ko'pincha hasharotlar zararkunandalari hisoblanadi. Piyoz pashshalari, tripslar va nematodalar davolanmasa, bir necha hafta ichida ko'chatni yo'q qilishi mumkin. Har bir zararkunandaning hayot aylanishini tushunish samarali nazorat usullarini o'z vaqtida qo'llash imkonini beradi.<\/p>\n

Piyoz kuyalari, ayniqsa, issiq va quruq ob-havoda faol bo'ladi, chunki ularning lichinkalari barglarga kirib, to'qimalarni yeb qo'yadi. Tamaki tripslari hujayra sharbati bilan oziqlanadi, bu esa barglarning keng sarg'ayishiga va jingalaklanishiga olib keladi. Poyasi nematodalari piyozning tagiga kirib, chirish va yorilishga olib keladi, bu esa hosilni keyingi saqlashni imkonsiz qiladi.<\/p>\n

Hasharotlarni nazorat qilish usullari<\/h2>\n

Piyoz pashshalaridan himoya qilish uchun samarali qishloq xo'jaligi amaliyoti ularni sabzi bilan birga ekishdir, uning hidi zararkunandalarni chalg'itadi. Agar oz sonli hasharotlar aniqlansa, sarimsoq damlamalari yoki qator oraliqlarini kul va tamaki changi aralashmasi bilan sepish qo'llaniladi. Keng tarqalgan zararkunandalar bo'lgan taqdirda, hosil yig'ishdan oldingi kutish vaqtiga qat'iy rioya qilgan holda, maxsus insektitsidlar qo'llaniladi.<\/p>\n

Ekishdan oldin issiqlik bilan ishlov berish tavsiya etiladi: 45\u201347\u00b0C haroratdagi suvga 15 daqiqa davomida botirish, bu trips va nematodalarni yo'q qilishga yordam beradi. Fitoverm kabi biologik mahsulotlardan foydalanish vegetatsiya davrining dastlabki bosqichlarida kimyoviy himoyaga xavfsizroq alternativ hisoblanadi.<\/p>\n

Zamburug'li va bakterial kasalliklar<\/h2>\n

Kasalliklar ko'pincha ortiqcha namlik va zich ekish sharoitida rivojlanadi. O'simliklar orasidagi havo aylanishi yomon bo'lganda bakterial chirish va zang tez tarqaladi. Profilaktika shikastlangan ekish materialini tashlash va ko'chatlarni dezinfektsiyalovchi eritmalar bilan ishlov berishni o'z ichiga oladi.<\/p>\n

Qo'ziqorinning birinchi belgisida, zararlangan o'simlik qismlarini olib tashlang va to'shaklarni mis tutgan fungitsidlar bilan ishlang. Tuproqni kuzatib borish muhim: agar tub chirishi aniqlansa, sug'orishni cheklang va ildizlarni shamollatish uchun tuproqni yumshating. Yog'och kulini qo'llash kabi an'anaviy usullardan foydalanish tuproqni quritishga va patogenlar uchun noqulay muhit yaratishga yordam beradi.<\/p>\n

O'g'itlash va sug'orishdagi xatolar<\/h2>\n

Oziq moddalar muvozanati patlarning sog'lom rivojlanishi uchun juda muhimdir. Haddan tashqari azot to'qimalarning bo'shashishiga va immunitetning pasayishiga olib keladi, yetishmovchilik esa barg uchlarining sarg'ayishiga olib keladi. Muvozanatli mineral qo'shimchalardan foydalanib, qat'iy ravishda jadvalga muvofiq o'g'itlash muhimdir.<\/p>\n\n\n\n\n\n

Sug'orish muntazam bo'lishi kerak, ammo ob-havo sharoitlariga moslashtirilishi kerak. Issiq havoda norma kvadrat metr uchun 10 litrni tashkil qiladi; salqin kunlarda suv hajmini ikki baravar kamaytiring. Noto'g'ri sug'orish o'simlikka stress keltirishi mumkin, bu esa darhol tuklar rangiga ta'sir qiladi.<\/p>\n

Tez-tez so'raladigan savollar: Tez-tez so'raladigan savollar (FAQ)<\/h2>\n

Nima uchun piyoz yomg'irdan keyin sarg'ayadi?<\/h3>\n

Haddan tashqari namlik azotning eriydi va ildizlarning haddan tashqari sug'orilishiga olib keladi, bu esa chirishga olib keladi. Tuproqni yumshatish va qurib ketishini tezlashtirish uchun oz miqdorda kul qo'shish tavsiya etiladi.<\/p>\n

Pashshalarni nazorat qilish uchun tuzdan foydalanish mumkinmi?<\/h3>\n

Tuz eritmasi (10 litr suvga 200 g) samarali, ammo tez-tez ishlatilsa, tuproq tuzilishiga zarar yetkazishi mumkin. Bu usul mavsumda ko'pi bilan bir marta qo'llanilishi kerak.<\/p>\n

Ovqatlantirishni qachon to'xtatish kerak?<\/h3>\n

O'g'itlarni qo'llash kutilgan hosildan 3-4 hafta oldin to'xtatiladi. Bu piyozning to'g'ri pishishi va shakar to'planishini ta'minlash uchun zarur.<\/p>\n
