Mushure mokupinda muzhizha, sezvo chiedza chinowedzera kusimba uye kutonhora kunowedzera, kutonhora mushedhi kwakanyanyisa uye chiedza chakanyanya kusimba, icho chave chiri chinhu chikuru chinokanganisa kukura kwezvirimwa.Kuti uderedze tembiricha uye kusimba kwechiedza mushedhi, shading mambure ndiyo yekutanga sarudzo.Zvakadaro, varimi vazhinji nguva pfupi yadarika vakashuma kuti kunyangwe tembiricha yadzikira mushure mekushandisamumvuri net, magaka ane matambudziko ekukura kusina simba uye goho rakaderera.Mushure mekunzwisisa kwakadzama, mupepeti anotenda kuti izvi zvinokonzerwa nehupamhi hwehuzha hwemambure ezuva anoshandiswa.Pane zvikonzero zviviri zvakakosha zvehuwandu hwe shading: imwe idambudziko rekushandisa nzira;imwe idambudziko remambure ezuva pacharo.Nekushandisa mambure ezuva, zvinotevera zvinofanirwa kutariswa kune:
Kutanga, tinofanira kusarudza zvakaruramasunshade net.Mavara emambure emumvuri pamusika anonyanya kutema uye sirivha-grey.Dema ine yakakwira shading mwero uye yakanaka kutonhora mhedzisiro, asi ine simba rakakura paphotosynthesis.Inonyanya kukodzera kushandiswa pazvirimwa zvinoda mumvuri.Kana yakashandiswa pane zvimwe zvirimwa zvinoda chiedza.Nguva yekuvhara inofanira kuderedzwa.Kunyangwe mambure esirivha-grey mumvuri asingashande mukutonhodza seatema, ane zvishoma zvinokanganisa photosynthesis yezvirimwa uye anogona kushandiswa pazvirimwa zvinopa chiedza.

Chechipiri, shandisa sunshade net nenzira kwayo.Kune mhando mbiri dze shading net yekuvhara nzira: yakazara kufukidzwa uye pavilion-mhando yekuvhara.Mumashandisirwo anoshanda, pavilion-mhando yekuvhara inoshandiswa zvakanyanya nekuda kwekutonhora kwayo kuri nani nekuda kwekutenderera kwemhepo.Iyo chaiyo nzira ndeye: shandisa skeleton ye arch shed kuti uvhare sunshade mambure kumusoro, uye usiye bhanhire remhepo re 60-80 cm pairi.Kana yakavharwa nefirimu, sunshade net haigoni kuvharwa zvakananga pafirimu, uye gaka rinopfuura 20 cm rinofanira kusiiwa kushandisa mhepo kuti itonhorere.Kunyangwe kuvhara mambure ezuva kunogona kuderedza tembiricha, zvakare kunoderedza kusimba kwechiedza, izvo zvine mhedzisiro yakaipa pa photosynthesis yezvirimwa, saka nguva yekuvhara yakakoshawo, uye inofanirwa kudzivirirwa zuva rese.Kana tembiricha yadzikira kusvika 30 ℃, mambure emumvuri anogona kubviswa, uye haafukidzwe nemazuva ane makore kuti aderedze mhedzisiro yakaipa pazvirimwa.
Ongororo yacho yakawanawo kuti dambudziko re shading net pachayo zvakare chinhu chisingagoni kuregererwa chinoita kuti shading rate ive yakanyanya.Parizvino, kune marudzi maviri makuru emambure ezuva pamusika: imwe inotengeswa nehuremu, uye imwe inotengeswa nenzvimbo.Mambure anotengeswa nehuremu anowanzo shandiswazve mambure, ayo ari emhando yakaderera uye ane hupenyu hwesevhisi hwemwedzi miviri kusvika pagore rimwechete.Iyi mambure inoratidzwa newaya gobvu, mambure akaoma, roughness, dense mesh, huremu hunorema, uye kazhinji yakakwirira shading rate.Pamusoro pe70%, hapana kurongedza kwakajeka.Mambure anotengeswa nenzvimbo anowanzo mambure matsva, ane hupenyu hwesevhisi hwemakore matatu kusvika mashanu.Iyi mambure inoratidzwa nehuremu huremu, kuchinjika kwakadzikama, yakatsetseka uye inopenya mambure epamusoro, uye huwandu hwakawanda hwekugadziriswa kwe shading rate, inogona kugadzirwa kubva ku30% kusvika 95%.svika.

Paunenge uchitenga shading net, isu tinofanira kutanga taziva kuti yakakwirira sei shading rate inodiwa pakuteurwa kwedu.Pasi pezuva rakananga muzhizha, kusimba kwechiedza kunogona kusvika 60,000-100,000 lux.Kune miriwo, iyo mwenje saturation poindi yemiriwo mizhinji ndeye 30,000-60,000 lux.Semuyenzaniso, iyo mwenje saturation point yemhiripiri i30,000 lux uye eggplant i40,000 lux.Lux, cucumber i55,000 lux.Chiedza chakanyanyisa chichava nechavo chikuru paphotosynthesis yemiriwo, zvichikonzera kuvharwa kwekabhoni dioxide, kufema zvakanyanya, nezvimwewo, uye iyo photosynthetic "masikati break" chiitiko chinoitika pasi pemamiriro echisikigo chinogadzirwa nenzira iyi.Nokudaro, kushandiswa kwemumvuri wekuvhara mambure neakakodzera shading rate haigoni kungoderedza kutonhora mushedhi isati yasvika uye shure kwemasikati, asiwo inovandudza photosynthetic kunyatsoshanda kwemiriwo, kuuraya shiri mbiri nebwe rimwe.
Tichifunga nezvekusiyana kwekuvhenekera kwezvirimwa uye kudiwa kwekudzora kutonhora kweshedhi, tinofanira kusarudza shading net ine shading rate yakakodzera.Kune avo vane low light saturation points sepepiresi, unogona kusarudza shading net ine high shading rate.Semuenzaniso, iyo shading rate ndeye 50% -70% kuve nechokwadi kuti kusimba kwechiedza mushedhi ndeye 30,000 lux.Kumagaka ane chiedza chakanyanya chekuzara kwemhando yemiti yemiti, unofanira kusarudza shading net ine shading rate yakaderera, yakadai seye shading rate ye 35-50%, kuti uone kuti chiedza chechiedza mushedhi ndeye 50,000 lux.
