Kuwala kukakhala kolimba komanso kutentha kumakwera, kutentha m’khola kumakhala kokwera kwambiri ndipo kuwalako kumakhala kolimba kwambiri, zomwe zakhala chinthu chachikulu chomwe chimakhudza kukula kwa mbewu.Kuchepetsa kutentha ndi kuwala kwamphamvu mu shedi,maukonde a shadingndi kusankha koyamba.Komabe, alimi ambiri posachedwapa ananena kuti ngakhale kuti kutentha kwatsika atagwiritsa ntchito ukonde woteteza dzuwa, mbewuzo zili ndi vuto la kusakula bwino komanso 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 yoyenera sunshade ukonde.
Mitundu ya maukonde amithunzi pamsika imakhala yakuda ndi silver-gray.Black imakhala ndi mithunzi yambiri komanso kuzizira kwabwino, koma imakhudza kwambiri photosynthesis.Ndiwoyenera kugwiritsidwa ntchito pa mbewu zokonda mthunzi.Ngati agwiritsidwa ntchito pa mbewu zokonda kuwala nthawi yobzala 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 kuti kuphimba ukonde wa sunshade kungachepetse kutentha, kumachepetsanso kuwala kwa dzuwa, komwe kumawononga kwambiri photosynthesis ya mbewu.Ntchito yaukadaulo waulimi wa Tianbao (ID: tianbaotsnjfw) Chifukwa chake, nthawi yophimba ndi yofunika kwambiri, ndipo iyenera kupewedwa tsiku lonse.Kuphimba kumachitika molingana ndi kutentha kwapakati pa 10:00 am mpaka 4:00 pm.Kutentha kukatsika mpaka 30 ° C, ukonde wamthunzi ukhoza kuchotsedwa, ndipo suphimbidwa pamasiku a mitambo kuti uchepetse kuwononga 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, kuwala kowala kumatha kufika 60,000-100,000 lux, pamene mbewu, malo obiriwira a masamba ambiri ndi 30,000-60,000 lux, monga tsabola kuwala saturation point ndi 30,000 lux, biringanya ndi 40,000 lux, nkhaka. ndi 55,000 lux.
Kuwala kochulukira kudzakhudza kwambiri photosynthesis ya mbewu, zomwe zimapangitsa kuti mayamwidwe a carbon dioxide atsekedwe komanso kupuma kwambiri.Ichi ndi chodabwitsa cha photosynthetic "kupuma kwa masana" komwe kumachitika pansi pa chilengedwe.Choncho, ntchito shading ukonde kuphimba ndi oyenera shading mlingo osati kuchepetsa kutentha mu okhetsedwa pamaso ndi masana, komanso kusintha photosynthetic dzuwa la mbewu, 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 malo otsika otsika monga tsabola, mukhoza kusankha ukonde wa shading ndi mlingo wapamwamba wa shading, monga mlingo wa shading wa 50% -70%, kuonetsetsa kuti kuwala kowala mu sheya ndi pafupifupi 30,000 lux;kwa nkhaka ndi malo ena owonjezera kuwala Kwa mitundu ya mbewu, muyenera kusankha ukonde wa shading wokhala ndi mthunzi wochepa, monga mthunzi wa 35-50%, kuonetsetsa kuti kuwala kwapadera mu shed ndi 50,000 lux.
