Pambuyo polowa m'chilimwe, pamene kuwala kumakhala kolimba komanso kutentha kumakwera, kutentha m'malo okhetsedwa kumakhala kwakukulu kwambiri ndipo kuwala kumakhala kolimba kwambiri, komwe kwakhala chinthu chachikulu chomwe chimakhudza kukula kwa mbewu.Kuti muchepetse kutentha ndi kuwala kowala musheti, maukonde a shading ndiye chisankho choyamba.Komabe, alimi ambiri posachedwapa adanena kuti ngakhale kutentha kwachepa atagwiritsa ntchitoukonde wamthunzi, nkhaka zimakhala ndi vuto la kukula kofooka ndi zokolola zochepa.Pambuyo pomvetsetsa mwatsatanetsatane, mkonzi amakhulupirira kuti izi zimayambitsidwa ndi kuchuluka kwa shading kwa ukonde wa sunshade womwe umagwiritsidwa ntchito.Pali zifukwa ziwiri zazikulu za chiwerengero cha shading: chimodzi ndi vuto la njira yogwiritsira ntchito;chinacho ndi vuto la ukonde wa sunshade wokha.Pogwiritsa ntchito maukonde a sunshade, zinthu zotsatirazi ziyenera kutsatiridwa:
Choyamba, tiyenera kusankha zolondolasunshade net.Mitundu ya maukonde amithunzi pamsika imakhala yakuda ndi silver-gray.Black imakhala ndi mithunzi yambiri komanso kuziziritsa bwino, koma imakhudza kwambiri photosynthesis.Ndiwoyenera kugwiritsidwa ntchito pa mbewu zokonda mthunzi.Ngati ntchito pa ena kuwala okonda mbewu.Nthawi yophimba iyenera kuchepetsedwa.Ngakhale ukonde wa silver-gray shade suthandiza kuziziritsa ngati wakuda, umakhala ndi mphamvu zochepa pa photosynthesis ya mbewu ndipo ungagwiritsidwe ntchito pa mbewu zokonda kuwala.

Chachiwiri, gwiritsani ntchito ukonde woteteza dzuwa moyenera.Pali mitundu iwiri ya njira zokutira ukonde: kuphimba kwathunthu ndi kuphimba kwamtundu wa pavilion.Muzochita zowoneka bwino, kuphimba kwamtundu wa pavilion kumagwiritsidwa ntchito kwambiri chifukwa cha kuzizira kwake chifukwa chakuyenda bwino kwa mpweya.Njira yeniyeni ndi: gwiritsani ntchito chigoba cha khola kuti muphimbe ukonde wa sunshade pamwamba, ndikusiya lamba wolowera mpweya wa 60-80 cm.Ngati ataphimbidwa ndi filimu, ukonde wa dzuwa sungathe kuphimba filimuyo, ndipo mpata wopitilira 20 cm uyenera kusiyidwa kuti mphepo izizire.Ngakhale kuphimba ukonde wa sunshade kungachepetse kutentha, kumachepetsanso kuwala kwa dzuwa, komwe kumakhudza kwambiri photosynthesis ya mbewu, choncho nthawi yophimba ndi yofunika kwambiri, ndipo iyenera kupeŵedwa tsiku lonse.Kutentha kukatsika mpaka 30 ℃, ukonde wamthunzi umatha kuchotsedwa, ndipo suphimbidwa pamasiku a mitambo kuti uchepetse zotsatira zoyipa za mbewu.
Kafukufukuyu adapezanso kuti vuto la ukonde wa shading palokha ndi chinthu chomwe sichinganyalanyazidwe chomwe chimapangitsa kuti chiwerengero cha shading chikhale chokwera kwambiri.Pakalipano, pali mitundu iwiri ikuluikulu ya maukonde a sunshade pamsika: imodzi imagulitsidwa ndi kulemera kwake, ndipo ina imagulitsidwa ndi dera.Maukonde omwe amagulitsidwa polemera amakhala ndi maukonde opangidwanso, omwe amakhala otsika kwambiri ndipo amakhala ndi moyo wa miyezi iwiri mpaka chaka chimodzi.Ukonde uwu umadziwika ndi waya wandiweyani, ukonde wolimba, roughness, mesh wandiweyani, kulemera kolemera, komanso kuchuluka kwa shading.Pamwamba pa 70%, palibe ma CD omveka bwino.Maukonde omwe amagulitsidwa ndi dera nthawi zambiri amakhala maukonde atsopano, okhala ndi moyo wazaka zitatu mpaka zisanu.Ukonde uwu umadziwika ndi kulemera kopepuka, kusinthasintha pang'ono, ukonde wosalala komanso wonyezimira, komanso kusintha kosiyanasiyana kwa shading, komwe kumatha kupangidwa kuchokera ku 30% mpaka 95%.kufika.

Pogula ukonde wa shading, choyamba tiyenera kudziwa kuti kuchuluka kwa shading kumafunika bwanji pakukhetsa kwathu.Pansi pa kuwala kwa dzuwa m'chilimwe, mphamvu ya kuwala imatha kufika 60,000-100,000 lux.Kwa ndiwo zamasamba, malo opepuka a masamba ambiri ndi 30,000-60,000 lux.Mwachitsanzo, tsabola wobiriwira ndi 30,000 lux ndipo biringanya ndi 40,000 lux.Lux, nkhaka ndi 55,000 lux.Kuwala kochulukira kudzakhudza kwambiri photosynthesis ya masamba, zomwe zimapangitsa kuti mayamwidwe a carbon dioxide atsekedwe, kupuma movutikira, ndi zina zambiri, ndipo chodabwitsa cha photosynthetic "masana yopuma" chomwe chimachitika pansi pamikhalidwe yachilengedwe chimapangidwa motere.Choncho, ntchito mthunzi ukonde chophimba ndi oyenera shading mlingo osati kuchepetsa kutentha mu okhetsedwa pamaso ndi masana, komanso kusintha photosynthetic dzuwa la masamba, kupha mbalame ziwiri ndi mwala umodzi.
Poganizira zowunikira zosiyanasiyana za mbewu komanso kufunikira kowongolera kutentha kwa shedi, tiyenera kusankha ukonde wa shading wokhala ndi mulingo woyenera wa shading.Kwa iwo omwe ali ndi mfundo zochepetsera kuwala monga tsabola, mukhoza kusankha ukonde wa shading ndi mlingo wapamwamba wa shading.Mwachitsanzo, kuchuluka kwa shading ndi 50% -70% kuwonetsetsa kuti kuwala kwanyumba kumakhala pafupifupi 30,000 lux.Kwa nkhaka zomwe zimakhala ndi malo otsika kwambiri a kuwala Kwa mitundu ya masamba, muyenera kusankha ukonde wa shading ndi mlingo wochepa wa shading, monga mthunzi wa 35-50%, kuonetsetsa kuti kuwala kwapadera mu shed ndi 50,000 lux.
