Sezvo chiedza chinowedzera kusimba uye tembiricha ichikwira, tembiricha mushedhi inokwira zvakanyanya uye chiedza chakanyanya kusimba, izvo zvave chinhu chikuru chinokanganisa kukura kwezvirimwa.Kudzikisa tembiricha uye kusimba kwechiedza mushedhi,shading netsndiyo yekutanga sarudzo.Zvakadaro, varimi vazhinji nguva pfupi yadarika vakati kunyangwe zvazvo tembiricha yakadzikira mushure mekushandisa mambure ezuva, mbesa dzine dambudziko rekusakura zvakanaka pamwe negoho 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 mambure akakodzera emumvuri wezuva.
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 ikashandiswa 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 emumvuri wezuva kuchigona kuderedza tembiricha, kunoderedzawo kusimba kwechiedza, izvo zvine mugumisiro wakashata paphotosynthesis yezvirimwa.Tianbao hunhu hwekurima tekinoroji sevhisi (ID: tianbaotsnjfw) Naizvozvo, nguva yekuvhara yakakoshawo, uye inofanirwa kudzivirirwa zuva rese.Kuvhara kunoitwa zvinoenderana nekupisa kuri pakati pe10:00 am na4:00 pm.Kana tembiricha yadzikira kusvika 30 °C, mambure emumvuri anogona kubviswa, uye haafukidzwe nemazuva ane makore kuti aderedze kukanganisa kwakashata 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, nepo zvirimwa, mwenje saturation nzvimbo yemiriwo mizhinji i30,000-60,000 lux, senge pepper light saturation point i30,000 lux, eggplant i40,000 lux cucumber. iri 55,000 lux.
Chiedza chakanyanyisa chichava nechanza chikuru pachirimwa photosynthesis, zvichikonzera kuvharika kwekabhoni dhaikisaidhi uye kufema kwakanyanya.Ichi ndicho chiitiko chephotosynthetic "noon break" inoitika pasi pemamiriro echisikigo.Nokudaro, kushandiswa kwekuvhara kwe shading net net yakafanira shading rate haigoni kuderedza kutonhora mushedhi isati yasvika uye masikati, asiwo inovandudza photosynthetic kubudirira kwezvirimwa, 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 nzvimbo yakaderera yekuzara kwechiedza sepepiresi, unogona kusarudza shading net ine shading rate yakakwirira, yakadai seye shading rate ye50% -70%, kuti uone kuti chiedza chechiedza mushedhi chinenge 30,000 lux;yemakaka uye mamwe mapeji epamusoro ekuzara kwechiedza Kune marudzi ezvirimwa, 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.
