nkhani

M'nyengo yotentha, pamene kuwala kumakula kwambiri ndipo kutentha kumakwera, kutentha m'malo okhetsedwa kumakhala kwakukulu kwambiri ndipo kuwala kumakhala kolimba kwambiri, komwe kumakhala chinthu chachikulu chomwe chimakhudza kukula kwa masamba.Popanga, alimi amasamba nthawi zambiri amagwiritsa ntchito njira yophimbamaukonde amithunzikuchepetsa kutentha mu shedi.
Komabe, palinso alimi ambiri a masamba omwe adanena kuti ngakhale kutentha kwatsika atagwiritsa ntchito ukonde wamthunzi, nkhaka zimakhala ndi vuto la kukula kofooka ndi zokolola zochepa.Kuchokera pamalingaliro awa, kugwiritsa ntchito maukonde a shading sikophweka monga momwe amaganizira, ndipo kusankha kopanda nzeru kungayambitse mithunzi yambiri ya shading ndikukhudza kukula kwa mbewu zamasamba.
Momwe mungasankhire ukonde wa sunshade mwasayansi komanso moyenera?
1. Sankhani mtundu wa ukonde wamthunzi malinga ndi mtundu wa masamba
Mtundu wa ukonde wamthunzi umawonjezeredwa panthawi yopanga zinthu zopangira.Maukonde amithunzi omwe ali pamsika pano amakhala akuda ndi silver-gray.Ukonde wamtundu wakuda uli ndi mthunzi wambiri komanso kuzizira kofulumira, koma umakhudza kwambiri photosynthesis, ndipo ndi yoyenera kugwiritsidwa ntchito pamasamba amasamba.Ngati imagwiritsidwa ntchito pamasamba okonda kuwala, nthawi yophimba iyenera kuchepetsedwa;Zili ndi zotsatira zochepa pa photosynthesis ndipo zili chonchooyenera masamba okonda kuwala monga nightshade.
2, kuchuluka kwa shading
Alimi akamagula maukonde amtundu wa sunshade, choyamba ayenera kudziwa kuchuluka kwa mithunzi yomwe amafunikira m'mashedi awo.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, ndipo malo owala a phwetekere ndi 70,000 lux.Kuwala kochulukira kudzakhudza photosynthesis ya masamba, zomwe zimapangitsa kuti mayamwidwe a carbon dioxide atseke, kupuma kwambiri, ndi zina zotero. Izi ndizochitika za photosynthetic "masana yopuma" zomwe zimachitika pansi pa chilengedwe.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.
Ukonde wakuda wakuda uli ndi mithunzi yambiri mpaka 70%.Ngati ukonde wakuda wakuda utagwiritsidwa ntchito, kuwala kowala sikungakwaniritse zofunikira za kukula kwa phwetekere, zomwe ndizosavuta kuyambitsa kukula kwa phwetekere komanso kusakwanira kwa zinthu za photosynthetic.Ambiri mwa maukonde amtundu wa silver-gray shade ali ndi mthunzi wa 40% mpaka 45%, ndi kuwala kwapakati pa 40,000 mpaka 50,000 lux, yomwe imatha kukwaniritsa zosowa za kukula kwa phwetekere.Choncho tomato amakutidwa bwino ndi maukonde a silver-gray shade.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 masamba, muyenera kusankha ukonde wa shading ndi mlingo wochepa wa shading, monga shading mlingo wa 35% -50%, kuonetsetsa kuti kuwala kwakukulu mu shed ndi 50,000 lux.
3. Onani nkhaniyo
Pali mitundu iwiri ya zida zopangira maukonde a sunshade pamsika pano.Imodzi ndi polyethylene 5000S yochuluka kwambiri yopangidwa ndi makampani a petrochemical ndi kuwonjezera kwa masterbatch amtundu ndi anti-aging masterbatch., Kulemera kopepuka, kusinthasintha kwapakati, kusalala kwa mauna, glossy, kusintha kwakukulu kwa shading rate, 30% -95% ikhoza kukwaniritsidwa, moyo wautumiki ukhoza kufika zaka 4.
Chinacho chimapangidwa kuchokera ku maukonde akale a sunshade kapena zinthu zapulasitiki.Mapeto ake ndi otsika, dzanja ndi lolimba, silika ndi wandiweyani, mauna ndi olimba, mauna ndi wandiweyani, kulemera kwake ndi kolemera, mithunzi nthawi zambiri imakhala yokwera, ndipo imakhala ndi fungo loipa, ndipo moyo wautumiki ndi waufupi. , zambiri zomwe zingagwiritsidwe ntchito kwa chaka chimodzi chokha.Nthawi zambiri kuposa 70%, palibe ma CD omveka bwino.
4. Samalani kwambiri pogula maukonde a sunshade polemera
Tsopano pali njira ziwiri zogulitsira maukonde a sunshade pamsika: imodzi ndi dera, ndipo ina ndi kulemera.Maukonde omwe amagulitsidwa potengera kulemera kwake nthawi zambiri amakhala maukonde opangidwanso, ndipo maukonde omwe amagulitsidwa potengera dera amakhala atsopano.
Alimi amasamba apewe zolakwika izi posankha:
1. Alimi amasamba omwe amagwiritsa ntchito maukonde a shading ndi osavuta kwambiri kugula maukonde okhala ndi mithunzi yapamwamba pogula maukonde a shading.Adzaganiza kuti mitengo yapamwamba ya shading ndiyozizira.Komabe, ngati mthunzi uli wochuluka kwambiri, kuwala kwa khola kuli kofooka, photosynthesis ya mbewu imachepetsedwa, ndipo zimayambira zimakhala zowonda komanso zolimba, zomwe zimachepetsa zokolola za mbewu.Choncho, posankha ukonde wa shading, yesetsani kusankha mthunzi ndi chiwerengero chochepa cha shading.
2. Pogula maukonde a shading, yesetsani kusankha mankhwala kuchokera kwa opanga akuluakulu ndi ma brand omwe ali ndi zizindikiro zotsimikizika, ndipo onetsetsani kuti mankhwala okhala ndi chitsimikizo cha zaka zoposa 5 amagwiritsidwa ntchito mu wowonjezera kutentha.
3. Makhalidwe a kutentha kwaukonde wa mthunzi wa dzuwa amawanyalanyaza aliyense.M'chaka choyamba, shrinkage ndi yochuluka, pafupifupi 5%, ndiyeno pang'onopang'ono imakhala yaying'ono.Pamene imachepa, chiwerengero cha shading chimawonjezekanso.Choncho, zizindikiro za kutentha kwa kutentha ziyenera kuganiziridwa pokonza ndi slot khadi.
Chithunzi pamwambapa ndikung'ambika kwa ukonde wamthunzi wa dzuwa chifukwa cha kuchepa kwa kutentha.Wogwiritsa ntchito akamagwiritsa ntchito kagawo kakang'ono ka khadi kuti akonze, amanyalanyaza chikhalidwe cha kutentha kwa kutentha ndipo samasunga malo ocheperako, zomwe zimapangitsa kuti ukonde wa sunshade ukhale wokhazikika kwambiri.
Pali mitundu iwiri ya njira zokutira ukonde: kuphimba kwathunthu ndi kuphimba kwamtundu wa pavilion.M'machitidwe othandiza, 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.
Kuphimba ukonde wamthunzi kuyenera kuchitika kuyambira 10:00 am mpaka 4:00 pm, malinga ndi kutentha.Kutentha kukatsika mpaka 30 ℃, ukonde wamthunzi ukhoza kuchotsedwa, ndipo suyenera kuphimbidwa ndi mitambo kuti uchepetse zotsatira zoyipa zamasamba..
