LED kukura mwenje chiedza chekuwedzera chirimwa chakagadzirirwa kugadzirwa kwemaruva nemiriwo nezvimwe zvinomera zvakasanganiswa nepamusoro-chaizvo tekinoroji.Kazhinji, zvirimwa zvemukati nemaruva zvichakura zvakanyanya uye zvakanyanya nekufamba kwenguva.Chikonzero chikuru ndechokushayikwa kwechiedza chemwenje.Nekuvhenekera nemwenje ye LED inokodzera mutsara unodiwa nemiti, haigoni kungokurudzira kukura kwayo, asiwo kuwedzera nguva yemaruva uye kuvandudza kunaka kwemaruva.
Kupesvedzera kweakasiyana spectrum e LED kukura mwenje
Miti yakasiyana-siyana ine zvinodikanwa zvakasiyana-siyana zve spectrum, senge tsvuku/blue 4:1 ye lettuce, 5:1 yemastrawberries, 8:1 kuitira chinangwa, uye zvimwe zvinoda kuwedzera infrared ne ultraviolet.Zvakanakisisa kugadzirisa chiyero chechiedza chitsvuku uye chebhuruu maererano nekukura kwechirimwa.
Pazasi pane maitiro eiyo spectral renji yekukura mwenje pachirimwa physiology.
280 ~ 315nm: diki pesvedzero pane morphology uye maitiro emuviri.
315 ~ 400nm: kushomeka kwechlorophyll, kunokanganisa iyo photoperiod mhedzisiro uye kudzivirira stem elongation.
400 ~ 520nm (blue): chiyero chekunyura chechlorophyll uye carotenoids ndicho chikuru, chine simba guru paphotosynthesis.
520 ~ 610nm (girinhi): mwero wekunyudzwa kwepigment hauna kukwirira.
Around 660nm (dzvuku): mwero wekunyudzwa kwechlorophyll wakadzikira, une mhedzisiro yakakosha paphotosynthesis uye photoperiod effect.
720 ~ 1000nm: mwero wakaderera wekutora, kukurudzira kuwedzera kwesero, kukanganisa maruva uye kumera kwembeu;
> 1000nm: inoshandurwa kuita kupisa.
Naizvozvo, mawavelengths akasiyana echiedza ane mhedzisiro yakasiyana pachirimwa photosynthesis.Chiedza chinodiwa pachirimwa photosynthesis chine wavelength ingangoita 400 kusvika 720 nm.Chiedza kubva pa400 kusvika pa520nm (blue) uye 610 kusvika 720nm (tsvuku) inopa zvakanyanya kuphotosynthesis.Chiedza kubva pa520 kusvika ku610 nm (girinhi) ine mwero wakaderera wekutorwa nechero pigment.
