Pasi pezuva rakananga muzhizha, kusimba kwechiedza kunogona kusvika 60000 kusvika 100000 lux.Kune zvirimwa, iyo mwenje saturation poindi yemiriwo mizhinji i30000 kusvika 60000 lux.Semuyenzaniso, iyo mwenje saturation point yemhiripiri ndeye 30000 lux, iyo eggplant i40000 lux, uye iyo yegaka i55000 lux.
Chiedza chakanyanyisa chichava nechavo chikuru pachirimwa photosynthesis, zvichikonzera kuvharwa kwekabhoni dioxide, kunyanya kufema kwakanyanya, nezvimwewo. Iyi ndiyo nzira iyo chiitiko che "masikati kuzorora" chephotosynthesis chinoitika pasi pemamiriro echisikigo.
Nokudaro, kushandisa shading nets ine shading rate yakakodzera haigoni kuderedza chete kutonhora mushedhi masikati masikati, asiwo kunatsiridza photosynthetic kubudirira kwezvirimwa, kuuraya shiri mbiri nedombo rimwe chete.
Tichifunga nezvekusiyana kwemwenje zvinodiwa zvezvirimwa uye kudiwa kwekudzora tembiricha yekudurura, isu tinofanirwa kusarudza shading net ine yakakodzera shading rate.Hatifanire kukara zvekuchipa tosarudza pamadiro.
Kune pepper ine yakaderera light saturation point, iyo shading net ine yakakwirira shading rate inogona kusarudzwa, semuenzaniso, iyo shading rate ndeye 50% ~ 70%, kuitira kuti kuve nechokwadi chekuti chiedza chechiedza mushedhi chinenge 30000 lux;Kune zvirimwa zvine yakakwira isochromatic saturation point yecucumber, iyo shading net ine yakaderera shading rate inofanirwa kusarudzwa, semuenzaniso, shading rate inofanira kunge iri 35 ~ 50% kuona kuti kupenya kwechiedza mushedhi i50000 lux.
