O'simliklarni yoritishni tanlash ko'pincha qarama-qarshi ma'lumotlarga to'la. Ishlab chiqaruvchilarning marketing strategiyalari fitolampalarning texnik xususiyatlarini buzib tushunishga olib keladi, bu esa keraksiz xarajatlarga va ekinlarning rivojlanishi bilan bog'liq muammolarga olib keladi. Yorug'lik oqimi fizikasini va o'simliklarning biologik ehtiyojlarini tushunish sizga reklama shiorlariga tayanmasdan uskunalarning samaradorligini mustaqil ravishda baholash imkonini beradi.<\/p>\n

Afsona #1: Vatt yorqinlikni bildiradi<\/h2>\n

Vattlarda (Vt) quvvat sarfi faqat tarmoqdan olinadigan energiya miqdorini belgilaydi, foton oqimining intensivligini emas. Quvvat va yorug'lik chiqishi o'rtasida to'g'ridan-to'g'ri bog'liqlik mavjud bo'lgan cho'g'lanma lampalardan farqli o'laroq, LED tizimlari elektr energiyasini yorug'likka samarali aylantirish printsipi asosida ishlaydi. Bir armatura 50 Vt iste'mol qilishi va kuchli nur hosil qilishi mumkin, boshqasi esa arzonroq 100 Vt ekvivalenti past samaradorlikni namoyish etadi.<\/p>\n

Yechim:<\/strong> Yorug'lik intensivligini baholashda vattlarni e'tiborsiz qoldiring. PPF (fotosintetik foton oqimi) ga sekundiga mikromollarda (\u03bcmol\/s) va yorug'lik moslamasining samaradorligiga (\u03bcmol\/J) e'tibor qarating. Bu raqamlar har bir vatt uchun fotosintez uchun qancha foydali yorug'lik olishingizni ko'rsatadi.<\/p>\n

Afsona #2: Har bir maydon uchun universal vatt qoidasi<\/h2>\n

"Kvadrat metrga vatt" hisoblash texnik jihatdan yaroqsiz, chunki u spektral tarkibni, linza dizaynini yoki osma balandligini hisobga olmaydi. Kosmosda yorug'lik tarqalishi diodlarning nominal quvvatiga emas, balki armatura optikasiga bog'liq.<\/p>\n

Yechim:<\/strong> Yorug'likni baholash uchun \u00b5mol\/m\u00b2\/s da o'lchangan PPFD (fotosintetik foton oqimi zichligi) dan foydalaning. Bu parametr barg yuzasiga tushadigan haqiqiy yorug'lik intensivligini ko'rsatadi.<\/p>\n\n\n\n\n\n\n

3-afsona: Quyoshning to'liq spektrini taqlid qilish<\/h2>\n

"Quyosh spektri" haqidagi da'volar ko'pincha o'simlik ehtiyojlari uchun optimallashtirilmagan lampalarni sotish uchun ishlatiladi. O'simliklar spektrning turli qismlaridan turli samaradorlik bilan foydalanadilar: xlorofillning yutilish cho'qqilari ko'k va qizil mintaqalarda to'plangan. Maishiy lampalardagi ortiqcha "quyoshli" yashil yoki sariq yorug'lik ko'pincha fotosintez uchun foydasiz balast bo'lib xizmat qiladi.<\/p>\n

Yechim:<\/strong> 440\u2013460 nm (ko'k) va 640\u2013680 nm (qizil) diapazonlarda dominant cho'qqilarga ega spektrogrammalarni qidiring. Keng spektr foydali, ammo u shunchaki quyosh nurini taqlid qilmasdan, ma'lum bir ekin ehtiyojlari uchun muvozanatli bo'lishi kerak.<\/p>\n

Afsona #4: LEDlar issiqlik chiqarmaydi<\/h2>\n

LEDlar taxminan 60\u2013801 TP3T energiyani issiqlikka aylantiradi. Biroq, sirtlarni to'g'ridan-to'g'ri isitadigan infraqizil to'lqinlarni chiqaradigan HPS lampalaridan farqli o'laroq, LEDlar issiqlikni zavoddan uzoqda, radiator orqali yuqoriga uzatadi.<\/p>\n

Yechim:<\/strong> Sotib olayotganda, ulkan alyuminiy sovutgichli modellarni tanlang. Faol sovutishning (ventilyatorlarning) yo'qligi dizaynni yanada ishonchli qiladi, chunki chang sovutgichni tiqib qo'ymaydi va issiqlik tarqalish samaradorligini pasaytiradi.<\/p>\n

5-afsona: O'simliklar va gullash uchun spektrlarni almashtirish<\/h2>\n

"O'sish uchun ko'k" va "gullash uchun qizil" o'rtasidagi farq soddalashtirilgan. O'simliklar uyg'un metabolizm uchun barqaror, to'liq spektrli yorug'likka muhtoj. Spektrlarni almashtirish faqat sanoat issiqxonalarida morfogenezni (poyaning balandligi, barg o'lchami) boshqarish uchun oqlanadi.<\/p>\n

Yechim:<\/strong> Uy sharoitida foydalanish uchun yuqori sifatli to'liq spektrli lampalarni tanlang, ular hayotning barcha bosqichlarida o'simliklarga qo'lda spektr sozlamalarini talab qilmasdan muvozanatli ovqatlanishni ta'minlaydi.<\/p>\n

6-afsona: Yashil chiroqlarga e'tibor bermaslik<\/h2>\n

Yashil yorug'lik (500\u2013550 nm) barg to'qimalariga chuqurroq kirib boradi va pastki soyabon qatlamlariga yetib boradi, bu yerda qizil va ko'k yorug'lik yuqori qatlamlar tomonidan so'riladi. Yashil spektrni yo'q qilish zich ekishlarda fotosintezning umumiy samaradorligini pasaytiradi.<\/p>\n

Yechim:<\/strong> Ko'k va qizildan tashqari, yashil va qizil chiroqlarni (730 nm) ham o'z ichiga olgan "keng" spektrli lampalarni tanlang. Bu o'simliklarning umumiy rivojlanishini yaxshilaydi.<\/p>\n

7-afsona: Teskari kvadrat qonuni<\/h2>\n

Masofa ikki baravar oshganda yorug'lik intensivligi to'rt baravar kamayadi degan matematik qoida faqat nuqtali manbalarga tegishli. LED panellari o'nlab diodlardan iborat massivlardir, shuning uchun yorug'lik intensivligi manbadan masofa oshgan sari ancha sekinroq kamayadi.<\/p>\n

Yechim:<\/strong> Nufuzli ishlab chiqaruvchilar tomonidan taqdim etilgan PAR xaritalaridan foydalaning. Ular paneldan turli masofalarda haqiqiy PPFD darajasini ko'rsatadi, bu sizga o'rnatish balandligini aniq sozlash imkonini beradi.<\/p>\n

Mif #8: LEDlarning ishlash muddati qisqa.<\/h2>\n

Yuqori sifatli diodlar 50 000 soatgacha ishlaydi. Nosozlikning asosiy sababi kristallning o'zining degradatsiyasi emas, balki drayverning (quvvat manbai) haddan tashqari qizib ketishidir.<\/p>\n

Yechim:<\/strong> Korpus tashqarisida joylashgan yoki ishonchli qizib ketishdan himoya qiluvchi drayverlarga ega armaturalarni tanlang. Bu butun tizimning ishlash muddatini 2-3 baravar uzaytiradi.<\/p>\n

Afsona #9: Uy lampalari yaroqsiz<\/h2>\n

4000\u20136500K rang haroratiga ega zamonaviy umumiy maqsadli LED lampalar ko'chatlar va kam parvarish talab qiladigan yopiq o'simliklarni o'stirish uchun yetarlicha intensivdir. \"Ko'chatlar <\/p>\n

Yechim:<\/strong> Agar siz maishiy lampalardan foydalansangiz, ularning past quvvatini va yuqori darajada ixtisoslashgan spektrlarning yo'qligini qoplash uchun ularni o'simliklarga iloji boricha yaqinroq (10-15 sm) joylashtiring.<\/p>\n

Afsona #10: Ko'rish qobiliyatiga zarar va kimyoviy xavf<\/h2>\n

Floresan lampalardan farqli o'laroq, LEDlar tarkibida simob yoki boshqa og'ir metallar mavjud emas. Ko'z xavfsizligiga kelsak, ko'zning charchashiga texnologiyaning o'zi emas, balki manbaning yuqori yorqinligi sabab bo'ladi. \"Fitolampalarning <\/p>\n

Yechim:<\/strong> Faol LEDlarga to'g'ridan-to'g'ri qarashdan saqlaning. Yuqori quvvatli uskunalar bilan ishlaganda, chiroqning nurlanish spektriga mos keladigan filtrli himoya ko'zoynaklarini taqing.<\/p>","protected":false},"excerpt":{"rendered":"
