Issiqxonada barqaror mikroiqlimni yaratish vegetatsiya mavsumini sezilarli darajada uzaytiradi va sabzavot hosildorligini oshiradi. Bog'bonning asosiy maqsadi haroratni maqbul chegaralarda ushlab turishdir, chunki to'satdan o'zgarishlar va qizib ketish o'simliklarning rivojlanishiga zararli ta'sir ko'rsatadi. Issiqxonalarda issiqlik almashinuvi mexanizmlarini tushunish ko'chatlar va yetuk o'simliklarni yetishtirishda keng tarqalgan xatolardan qochishga yordam beradi. To'g'ri haroratni saqlash issiqxonaning dizayn xususiyatlarini ham, ma'lum sabzavot turlarining biologik ehtiyojlarini ham hisobga oladigan kompleks yondashuvni talab qiladi.<\/p>\n

\"Ideal<\/p>\n

O'simliklar uchun optimal harorat oralig'i<\/h2>\n

Ko'pgina sabzavot ekinlari uchun 25 dan 30 daraja Selsiygacha bo'lgan qulay harorat oralig'i ideal hisoblanadi. Bu chegaradan oshib ketish qizib ketishga olib keladi, bu esa o'simliklarga jiddiy stress keltirib chiqaradi, fotosintezni sekinlashtiradi va kasallik xavfini oshiradi. Haddan tashqari haroratlarda ko'plab navlarning changi steril bo'lib, meva pishishiga butunlay to'sqinlik qiladi.<\/p>\n

Pomidor, bodring va qalampir kabi issiqliksevar ekinlar 35 daraja Selsiy (95 daraja Farengeyt) gacha bo'lgan haroratga bardosh bera oladi, ammo bu faqat yetarli sug'orish va shamollatish ta'minlangan taqdirdagina mumkin. Shuni yodda tutish kerakki, 28 darajadan (82 daraja Farengeyt) yuqori harorat tungi soyalarda changlanishga salbiy ta'sir qiladi. Salat bargi, ismaloq va turp kabi sovuqqa chidamli o'simliklar 20-25 daraja Selsiy (68-77 daraja Farengeyt) salqin sharoitlarda yaxshi o'sadi.<\/p>\n

Bir xil issiqxonada turli xil issiqlik talablariga ega ekinlarni aralashtirish xato. Agar siz bodring va salatni bir xil joyda o'stirsangiz, ikkalasi uchun ham ideal sharoit yaratishning iloji yo'q. O'sish amaliyotingizni soddalashtirish uchun har doim o'xshash ehtiyojlarga ega o'simliklarni guruhlang.<\/p>\n

\"Issiqlikni<\/p>\n

Issiqxona maydonini isitish fizikasi<\/h2>\n

Issiqxona quyosh energiyasini saqlash moslamasi vazifasini bajaradi, shaffof devorlari orqali qisqa to'lqinli nurlanishni uzatadi. Ichkariga kirgandan so'ng, energiya tuproq va o'simliklar tomonidan so'riladi, uni termal infraqizil nurlanishga aylantiradi, keyin esa yopiq joyda ushlanib qoladi. Bu issiqxona effektini yaratadi va haroratni tashqi haroratdan sezilarli darajada yuqori darajada ushlab turadi.<\/p>\n

Issiqxonadagi havo hajmi cheklangan, shuning uchun u ochiq havoga qaraganda ancha tezroq qiziydi. Quyoshli kunlarda, to'g'ri shamollatish bo'lmasa, ichidagi havo bir necha soat ichida kritik haroratga yetishi mumkin. Havo aylanishining yetarli emasligi vaziyatni yanada og'irlashtiradi va juda yuqori haroratli turg'un zonalarni yaratadi.<\/p>\n

Faol shamollatish usullari<\/h2>\n

Issiq kunlarda haroratni pasaytirishning eng samarali va arzon usuli muntazam shamollatish bo'lib qolmoqda. Ochiq eshiklar va shamollatish teshiklari toza havo ta'minotini ta'minlaydi, bu esa isitilgan havoni tashqariga siqib chiqaradi. Kunduzi to'plangan issiqlikni tun davomida saqlab qolish uchun kechqurun barcha teshiklarni yopish muhimdir.<\/p>\n

Issiqlik bilan ishlaydigan shamollatish teshiklari kabi avtomatik tizimlar issiqxonani parvarish qilishni sezilarli darajada soddalashtiradi. Ular harorat ko'tarilganda pistondagi maxsus birikmani kengaytirish orqali ishlaydi, bu esa derazalarning inson aralashuvisiz ochilishiga imkon beradi. Biroq, haddan tashqari issiq davrlarda shamollatish teshiklarining o'zi kerakli darajani saqlab turish uchun yetarli bo'lmasligi mumkin.<\/p>\n

\"Issiqxona<\/p>\n

Sirkulyatsiya uchun fanatlardan foydalanish<\/h2>\n

Agar tabiiy shamollatish yetarli bo'lmasa, majburiy shamollatgichlarni o'rnatish kerak. Ular nafaqat haroratni pasaytiradi, balki namlikning turg'unligini ham oldini oladi, bu esa qo'ziqorin kasalliklari va mog'orlarning oldini olishning ajoyib vositasidir. To'g'ri joylashtirilgan shamollatgich o'simliklarning tojiga havo puflashi kerak, lekin poyalarga zarar etkazadigan bo'ron kuchidagi havo oqimini yaratmasligi kerak.<\/p>\n

Samarali ishlash uchun ikki blokli tizimdan foydalanish yaxshidir: biri toza havo olish uchun, ikkinchisi issiq havo chiqarish uchun. Uskunani tanlashda, issiqxonaning hajmini hisobga oling, shunda u ichidagi havoni to'liq almashtirish uchun yetarli quvvatga ega bo'ladi. Agar byudjetingiz cheklangan bo'lsa, hatto namlikka chidamli uy modellaridan ham foydalanish mumkin.<\/p>\n

\"Issiqxonada<\/p>\n

Soyalash va quyoshdan himoya qilish usullari<\/h2>\n

Soya to'rlari quyoshning kuchli nurlari paytida haroratning keskin o'zgarishining oldini olishga yordam beradi. Soyalanish darajasi alohida tanlanadi: 45% bodring uchun optimal, 60% esa pomidor yoki baqlajon uchun ideal. To'rni issiqxonadan tashqariga o'rnatishda, qoplama materialining issiqligini jismonan to'sib qo'ygani uchun, 80% gacha bo'lgan yuqori qoplama zichligi maqbuldir.<\/p>\n

Shu bilan bir qatorda, siz issiqxonaning tashqi tomoniga surtilgan bo'r eritmalari yoki oqlash kabi maishiy mahsulotlardan foydalanishingiz mumkin. Tomni agrofiber yoki eski och rangli mato bilan qoplash ham samarali hisoblanadi. Ichkarida "hammom" effektini yaratmaslik uchun shamollatishni ta'minlash muhimdir.<\/p>\n

\"Agar<\/p>\n

Havo namligini tartibga solish<\/h2>\n

Issiqxonada optimal namlik kamida 50\u201360\u00b0C darajasida saqlanishi kerak. Quruq havo fotosintezni sekinlashtiradi va o'simliklarni o'rgimchak oqadilar kabi zararkunandalarga zaif qoldiradi. Namlikni muntazam ravishda sug'orish yo'llari yoki suv idishlarini o'rnatish orqali oshirish mumkin.<\/p>\n

Yuqoridan purkash bilan sug'orish tizimlari issiq kunlarda qulay mikroiqlim yaratadi. Biroq, bunday tizimlardan foydalanganda, namlikning barglarda uzoq vaqt turg'un bo'lishining oldini olish uchun yaxshi shamollatishni ta'minlash muhimdir. Chirishning oldini olish uchun kechqurun bargdan sug'orishni to'xtatish yaxshidir.<\/p>\n\n\n\n\n\n\n

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

Issiq havoda issiqxonadagi yo'llarni sug'orishim kerakmi?<\/h3>\n

Ha, bu namlikni tezda oshirish va havo haroratini pasaytirishning eng oson usullaridan biridir. Suv yo'llar yuzasidan bug'lanib ketganda, atrofdagi hududni sovutadi va o'simliklar uchun qulay sharoit yaratadi. Quyosh nurlari eng yuqori bo'lgan vaqtda ushbu protsedurani kuniga 2-3 marta takrorlang.<\/p>\n

Issiqxona o'simliklaringiz juda issiq ekanligini qanday bilasiz?<\/h3>\n

Birinchi belgi - nam tuproqda ham kunduzgi vaqtda barglarning so'lishi. Barg pichoqlari ham burishadi, gullar va tuxumdonlar tushadi. Uzoq vaqt qizib ketganda, barg qirralari jigarrang rangga aylanishi mumkin.<\/p>\n

Soyalash uchun oddiy dokadan foydalanish mumkinmi?<\/h3>\n

Doka juda kam soya beradi va ultrabinafsha nurlanishi ta'sirida tezda yomonlashadi. 17\u201330 g\/m\u00b2 zichlikdagi maxsus soya to'rlari yoki agrofiberdan foydalanish yaxshiroqdir. Ular bardoshli, nafas oladigan va yorug'likning bir tekis tarqalishini ta'minlaydi.<\/p>","protected":false},"excerpt":{"rendered":"
