Cov teebmeem ntawm LED teeb sib xyaw rau kev loj hlob thiab kev ruaj ntseg tom qab cog qoob loo ntawm Barley nyom hauv cov chaw cog qoob loo
Txoj kev tshawb no tau tshawb xyuas seb qhov sib txawv ntawm LED teeb sib txuas ua ke cuam tshuam li cas rau kev cog qoob loo, kev loj hlob, kev ua haujlwm photosynthetic, thiab tom qab sau qoob loo zoo ntawm barley nyom (Hordeum vulgare L.) loj hlob nyob rau hauv lub kaw cog Hoobkas, thiab tshuaj xyuas lub luag hauj lwm ntawm cov txheej txheem ntim hauv kev ruaj ntseg tom qab sau qoob loo. Cov kev tshawb fawb no tsom los txheeb xyuas cov teeb pom kev zoo thiab ntim cov tswv yim rau xyoo ruaj khov -ib puag ncig kev tsim khoom thiab txuas ntxiv txee lub neej ntawm barley nyom. Qhov kev sim tau ua nyob rau hauv lub chaw tswj kev cog qoob loo nrog ib puag ncig tas li ntawm 23 ± 1 degree, 60 ± 10% txheeb ze av noo, thiab 12-teev lub teeb / 12-teev tsaus ntuj photoperiod.
Tsib LED kev kho mobtau sim: 100% liab (R10), 100% xiav (B10), thiab peb xim liab-xiav sib xyaw spectra (R7B3, R5B5, R3B7), tag nrho ntawm photosynthetic photon flux ntom ntawm 160 μmol m⁻² s⁻¹. Barley noob tau soaked rau 6 teev ua ntej sowing, thiab germination thiab loj hlob ntsuas tau ntsuas rau 7 hnub. Photosynthetic kev ua tau zoo raug soj ntsuam los ntawm qhov siab tshaj plaws quantum tawm los ntawm photosystem II (Fv / Fm). Rau kev soj ntsuam tom qab sau qoob, cov noob qoob loo tau khaws cia ntawm 8 ± 1℃rau 14 hnub siv peb txoj kev ntim khoom: kev tswj, corrugated thawv, thiab hloov pauv huab cua ntim (MAP) nrog tus nqi xa tawm oxygen (OTR) ntawm 40,000 cc·m⁻²·day⁻¹·atm⁻¹. Kev poob phaus thiab suav microbial raug kaw thaum khaws cia. Cov txiaj ntsig tau sim pom tias monochromatic liab LED (R10) ua tau zoo dua lwm yam kev kho mob. Nws ua tiav qhov siab tshaj plaws germination tus nqi (95.3%), germination zog, thiab germination tus nqi, nrog rau cov kev loj hlob zoo tshaj plaws nrog rau cov nroj tsuag siab tshaj plaws, hnyav tshaj tua tshiab thiab qhuav hnyav, thiab cov cag ntev.
Tus nqi Fv/Fm mus txog 0.81 nyob rau hauv R10, qhia qhov muaj zog photosynthetic efficiency, thaum xiav -kev kho mob nplua nuj (R3B7, B10) muaj qis Fv/Fm (0.79) thiab kev loj hlob tsis zoo thiab kev loj hlob. Hauv kev khaws cia tom qab sau qoob, hom ntim tau muaj kev cuam tshuam ntau dua rau qhov zoo thiab kev nyab xeeb ntawm microbial ntau dua li ua ntej- khaws cov kev kho LED. MAP ua tau zoo txo qhov poob phaus tshiab rau 4.4–5.1%, qis dua qhov kev tswj hwm (10.9–11.7%) thiab lub thawv ntim khoom (7.1–7.6%). Nws kuj tseem cuam tshuam qhov kev loj hlob ntawm tag nrho cov kab mob aerobic, coliforms, thiab fungi, ua tau raws li cov qauv kev nyab xeeb microbial rau kev npaj-- noj zaub mov. Tsis muaj kev cuam tshuam tseem ceeb hauv kev sib tham tau pom nyob nruab nrab ntawmLED kev kho mobthiab cov txheej txheem ntim khoom. Hauv kev xaus, lub teeb liab monochromatic (R10) yog lub teeb pom kev zoo tshaj plaws rau barley nyom hauv cov chaw cog qoob loo, txhawb kev loj hlob zoo, kev loj hlob zoo, thiab kev ua haujlwm siab photosynthetic.
Rau kev khaws cia tom qab sau qoob loo, MAP nrog OTR 40,000 muaj txiaj ntsig zoo hauv kev txo qhov hnyav thiab kev loj hlob ntawm microbial. Kev koom ua ke R10 LED teeb pom kev zoo thaum cog nrog kev txhim kho MAP cia tuaj yeem txhawb kev ruaj khov, xyoo- puag ncig kev lag luam ntawm barley nyom nrog rau lub neej ntev thiab txhim kho zoo.
