Emva kokungena ehlotyeni, njengoko ukukhanya kuba namandla kwaye nobushushu buphakama, iqondo lobushushu kwishedi liphezulu kakhulu kwaye ukukhanya kunamandla kakhulu, okuye kwaba yinto ephambili echaphazela ukukhula kwezityalo.Ukunciphisa iqondo lokushisa kunye nokukhanya kokukhanya kwi-shed, inetha ze-shading zikhetho lokuqala.Nangona kunjalo, amafama amaninzi kutshanje anike ingxelo yokuba nangona iqondo lobushushu liye lehla emva kokusebenzisa iumnatha womthunzi, ukhukhamba uneengxaki zokukhula obuthathaka kunye nesivuno esiphantsi.Emva kokuqonda okucacileyo, umhleli ukholelwa ukuba oku kubangelwa izinga eliphezulu le-shading ye-sunshade net esetyenzisiweyo.Kukho izizathu ezibini eziphambili zezinga eliphezulu le-shading: enye yingxaki yendlela yokusetyenziswa;enye ingxaki ye-sunshade net ngokwayo.Ukusetyenziswa kweminatha ye-sunshade, le miba ilandelayo kufuneka ithathelwe ingqalelo:
Okokuqala, kufuneka sikhethe okulungileyosunshade net.Imibala yeminatha yomthunzi kwimarike ubukhulu becala imnyama kunye nesilivere-ngwevu.Umnyama unezinga eliphezulu lomthunzi kunye nefuthe elihle lokupholisa, kodwa unempembelelo enkulu kwi-photosynthesis.Ilungele ukusetyenziswa kwizityalo ezithanda umthunzi.Ukuba isetyenziswe kwezinye izityalo ezithanda ukukhanya.Ixesha lokugubungela kufuneka lincitshiswe.Nangona umnatha womthunzi osilver-grey ungasebenzi kakuhle ekupholiseni njengomnyama, unempembelelo encinci kwi-photosynthesis yezityalo kwaye unokusetyenziswa kwizityalo ezithanda ukukhanya.

Okwesibini, sebenzisa umnatha we-sunshade ngokuchanekileyo.Kukho iintlobo ezimbini zeendlela zokugubungela umnatha: ukugubungela ngokupheleleyo kunye nohlobo lwe-pavilion.Kwizinto ezisebenzayo, uhlobo lwe-pavilion lusetyenziswa kakhulu ngenxa yesiphumo esingcono sokupholisa ngenxa yokujikeleza komoya.Indlela ekhethekileyo yile: sebenzisa i-skeleton ye-arch shed ukugubungela umnatha we-sunshade phezulu, kwaye ushiye ibhanti yokungena umoya we-60-80 cm kuyo.Ukuba ugqunywe ngefilimu, umnatha we-sunshade awukwazi ukugqunywa ngokuthe ngqo kwifilimu, kwaye umsantsa ongaphezulu kwe-20 cm kufuneka ushiywe ukusebenzisa umoya ukupholisa.Nangona ukugquma umnatha we-sunshade kunokunciphisa ubushushu, kukwanciphisa ukukhanya, okunefuthe elibi kwi-photosynthesis yezityalo, ngoko ke ixesha lokugquma libaluleke kakhulu, kwaye kufuneka liphetshwe imini yonke.Xa amaqondo obushushu ehla ukuya kuma 30 ℃, inothi yomthunzi inokususwa, kwaye ayigqunywanga ngeentsuku ezinamafu ukunciphisa iziphumo ezibi kwizityalo.
Uphando luphinde lwafumanisa ukuba ingxaki ye-shading net ngokwayo yinto engenakuhoywa ebangela ukuba izinga lomthunzi libe phezulu kakhulu.Okwangoku, kukho iintlobo ezimbini eziphambili zeenetha ze-sunshade kwiimarike: enye ithengiswa ngobunzima, kwaye enye ithengiswa ngommandla.Iinetha ezithengiswayo ngobunzima zixhaphakile zinetha zezixhobo ezisetyenzisiweyo, ezizinetha ezikumgangatho ophantsi kwaye zinenkonzo yobomi beenyanga ezi-2 ukuya kunyaka omnye.Lo mnatha ubonakaliswe ngocingo olushinyeneyo, umnatha oqinileyo, uburhabaxa, umnatha oshinyeneyo, ubunzima obunzima, kunye nesantya esiphezulu somthunzi ngokubanzi.Ngaphezulu kwe-70%, akukho phakheji ecacileyo.Iinethi ezithengiswa ngokwendawo zidla ngokuba yiminatha yemathiriyeli emitsha, kunye nobomi benkonzo obuyiminyaka emi-3 ukuya kwemi-5.Lo mnatha ubonakaliswe ngobunzima obulula, ukuguquguquka okuphakathi, indawo egudileyo kunye ne-shiny net, kunye noluhlu olubanzi lohlengahlengiso lwe-shading rate, olunokuthi lwenziwe ukusuka kwi-30% ukuya kwi-95%.fika.

Xa kuthengwa umnatha we-shading, kufuneka siqale sinqume ukuba izinga le-shading liphezulu kangakanani kwi-shed yethu.Ngaphantsi kwelanga elithe ngqo ehlotyeni, ukukhanya kokukhanya kunokufikelela kwi-60,000-100,000 lux.Kwimifuno, indawo yokuzalisa ukukhanya kwimifuno emininzi yi-30,000-60,000 lux.Umzekelo, indawo yokugcwala kwepepile yi-30,000 lux kunye ne-eggplant yi-40,000 lux.Lux, cucumber yi 55,000 lux.Ukukhanya okugqithisileyo kuya kuba nefuthe elikhulu kwi-photosynthesis yemifuno, okubangelwa ukuvalelwa kwe-carbon dioxide, ukuphefumla ngokugqithiseleyo, njl.Ngoko ke, ukusetyenziswa kwesigqubuthelo somthunzi kunye nesantya esifanelekileyo se-shading asikwazi ukunciphisa kuphela iqondo lokushisa kwi-shed ngaphambi nangemva kwemini, kodwa nokuphucula ukusebenza kwe-photosynthetic yemifuno, ukubulala iintaka ezimbini ngelitye elinye.
Ukuqwalasela iimfuno zokukhanyisa ezahlukeneyo zezityalo kunye nesidingo sokulawula ukushisa kwe-shed, kufuneka sikhethe umnatha womthunzi kunye nesantya esifanelekileyo somthunzi.Kulabo abanamanqaku aphantsi okuzalisa ukukhanya okufana nepepper, unokukhetha umnatha we-shading kunye nesantya esiphezulu se-shading.Ngokomzekelo, izinga le-shading yi-50% -70% ukuqinisekisa ukuba ukukhanya kokukhanya kwi-shede malunga ne-30,000 lux.Iikomkomere ezinomlinganiselo ophezulu wokuzalisa ukukhanya kwiintlobo zemifuno, kufuneka ukhethe umnatha we-shading kunye nesantya esincinci se-shading, njengesilinganiselo se-shading ye-35-50%, ukuqinisekisa ukuba ukukhanya kokukhanya kwi-shed yi-50,000 lux.
