Cov nyhuv ntawm cov nroj tsuag loj hlob sib xws rau LED Wavelengths

Qhov cuam tshuam cov nroj tsuag loj hlob ntawm LED wavelength 1. Cov xim kub thiab ntws ntawm cov teeb pom kev zoo: cov xim kub thiab ntws ntawm cov teeb pom kev zoo yog pom los ntawm tib neeg lub qhov muag, thiab cov nyhuv photosynthetic ntawm cov nroj tsuag rau lub teeb tsis saib xim kub thiab lumen. 2. Cov nyhuv ntawm qhov ntau ntawm spectrals ntawm cov nroj tsuag physiology: 280 315nm ——> Qhov cuam tshuam rau daim ntawv thiab cov txheej txheem physiological yog qhov tsawg heev. 315 400 nm ——> Kev nqus chlorophyll tsawg dua, cuam tshuam rau lub sijhawm ua haujlwm ntawm lub voj voog kho qhov muag, thiab tiv thaiv cov stems los ntawm kev ncua. 400 520nm (xiav) —> Qhov kev faib ua feem ntawm chlorophyll thiab carotene nqus yog qhov loj tshaj plaws thiab muaj txiaj ntsig zoo tshaj plaws ntawm photosynthesis. 520 610nm (ntsuab) —> Qhov nqus ntawm pigments tsis siab. 610 720nm (liab) —> Qhov nqus ntawm chlorophyll yog qhov tsawg, uas muaj kev cuam tshuam tseem ceeb ntawm photosynthesis thiab cov nyhuv ntawm photosynthesis 720 1000Nm. ——> Tsawg nqus tus nqi, stimulating hlwb ntev, thiab cuam tshuam rau paj thiab noob germination. 1000NM ——> Hloov ua lwm yam calories. Los ntawm cov ntaub ntawv saum toj no, qhov cuam tshuam ntawm qhov sib txawv wavelengths ntawm lub teeb ntawm cov nroj tsuag photosynthesis sib txawv. Lub teeb tsim ntawm cov nroj tsuag photosynthesis yog hais txog 400 720nm. Lub teeb ntawm 400 520nm (xiav) thiab 610 720nm (liab) pab txhawb ntau tshaj plaws rau photosynthesis. 520 610nm (ntsuab) lub teeb, qhov piv ntawm cov nroj tsuag pigment haum yog tsawg heev. 3. Raws li cov hauv paus ntsiab lus saum toj no, cov teeb pom kev zoo yog tsim los ua peb hom: liab thiab xiav ua ke, tag nrho xiav, thiab tag nrho cov liab los muab ob lub wavelengths ntawm liab thiab xiav. Nyob rau hauv cov nqe lus ntawm kev pom kev, cov xim liab thiab xiav ua ke ntawm cov nroj tsuag teeb liab yog liab. Lub teeb dawb LED teeb, feem ntau yog cov tub ntxhais xiav los txhawb cov hmoov fluorescent daj, yog li ua rau pom cov teeb pom kev dawb. Nyob rau hauv cov nqe lus ntawm lub zog faib, muaj ob lub ncov qhov tseem ceeb nyob rau hauv xiav cheeb tsam ntawm 445nm thiab ib tug 550nm daj-ntsuab cheeb tsam. Lub teeb liab 610 720nm xav tau los ntawm cov nroj tsuag yog qhov tsis txaus. Qhov no piav qhia vim li cas cov nroj tsuag loj hlob tsis zoo nyob rau hauv lub teeb dawb LED. 4. Qhov kev faib ua feem ntawm cov teeb liab thiab xiav ntawm cov teeb pom kev zoo yog feem ntau ntawm 5: 1 10: 1, feem ntau yog qhov piv ntawm 7 9: 1. 5. Thaum siv cov teeb pom kev zoo los sau cov nroj tsuag, qhov siab ntawm nplooj yog li 0.5 meters. Kev tsim ntau yam ntawm LED teeb hlaws. Yog tias koj yuav tsum kho nws, koj tuaj yeem sab laj nrog peb cov neeg siv khoom!
