Ehlobo, njengoba ukukhanya kuba namandla futhi izinga lokushisa likhuphuka, izinga lokushisa eshedini liphakeme kakhulu futhi ukukhanya kunamandla kakhulu, okuba yisici esiyinhloko esithinta ukukhula kwemifino.Ekukhiqizeni, abalimi bemifino bavame ukusebenzisa indlela yokumbozaamanetha anomthunziukunciphisa izinga lokushisa eshede.
Nokho, kukhona nabalimi abaningi bemifino ababike ukuthi nakuba izinga lokushisa liye lehla ngemva kokusebenzisa inetha lomthunzi, ukhukhamba unezinkinga zokukhula okubuthakathaka kanye nesivuno esincane.Kusukela kulo mbono, ukusetshenziswa kwamanetha e-shading akulula njengokucatshangelwa, futhi ukukhetha okungenangqondo kungase kuholele emazingeni okushisa ngokweqile futhi kuthinte ukukhula kwezitshalo zemifino.
Ungakhetha kanjani inetha le-sunshade ngokwesayensi nangokunengqondo?
1. Khetha umbala wenetha lomthunzi ngokuya ngohlobo lwemifino
Umbala wenetha lomthunzi wengezwe ngesikhathi senqubo yokukhiqiza impahla eluhlaza.Amanethi omthunzi okwamanje asemakethe ikakhulukazi amnyama kanye nesiliva-grey.Inetha lomthunzi omnyama linezinga eliphezulu lomthunzi kanye nokupholisa ngokushesha, kodwa linomthelela omkhulu ku-photosynthesis, futhi lifaneleka kakhulu ukusetshenziswa emifino enamaqabunga.Uma isetshenziselwa imifino ethanda ukukhanya, isikhathi sokumboza kufanele sincishiswe;Inomphumela omncane ku-photosynthesis futhi injaloilungele imifino ethanda ukukhanya efana ne-nightshade.
2, izinga le-shading elicacile
Lapho abalimi bemifino bethenga amanetha e-sunshade, kufanele baqale banqume ukuthi badinga isilinganiso esingakanani somthunzi welanga emashedeni abo.Ngaphansi kokukhanya kwelanga ehlobo, ukukhanya kungafinyelela ku-60,000-100,000 lux.Emifino, indawo yokugcwala ukukhanya kwemifino eminingi i-30,000-60,000 lux.Isibonelo, indawo ekhanyayo kapelepele iyi-30,000 lux futhi isitshalo seqanda siyi-40,000 lux.I-Lux, ikhukhamba yi-55,000 lux, futhi indawo yokugcwala ukukhanya kukatamatisi yi-70,000 lux.Ukukhanya okudlulele kuzothinta i-photosynthesis yemifino, okuholela ekumunceni kwe-carbon dioxide okuvinjiwe, ukuphefumula ngokweqile, njll. Lesi yisimo se-photosynthetic "ikhefu lasemini" esenzeka ngaphansi kwezimo zemvelo.Ngakho-ke, ukusetshenziswa kwesembozo senetha lomthunzi ngesilinganiso esifanele se-shading akukwazi ukunciphisa izinga lokushisa endaweni ngaphambi nangemva kwasemini, kodwa futhi kuthuthukise ukusebenza kahle kwe-photosynthetic yemifino, ukubulala izinyoni ezimbili ngetshe elilodwa.
I-black shading inetha inezinga eliphezulu le-shading elifika ku-70%.Uma kusetshenziswa inetha elimnyama le-shading, ukukhanya okukhanyayo akukwazi ukuhlangabezana nezidingo ezijwayelekile zokukhula kukatamatisi, okulula ukubangela ukukhula okunemilenze katamatisi kanye nokuqoqwa okwanele kwemikhiqizo ye-photosynthetic.Iningi lamanethi omthunzi ompunga anenani le-shading lika-40% kuya ku-45%, kanye nokudlulisa ukukhanya kwe-40,000 kuya ku-50,000 lux, okungahlangabezana nezidingo ezijwayelekile zokukhula kukatamatisi.Ngakho-ke utamatisi umbozwa kangcono ngamanetha omthunzi wesiliva-grey.Kulabo abanephuzu eliphansi lokugcwala kokukhanya okufana nopelepele, ungakhetha inetha le-shading enezinga eliphakeme le-shading, njengesilinganiso se-shading sika-50% -70%, ukuze uqinisekise ukuthi ukukhanya kokukhanya eshedini cishe ku-30,000 lux;amakhukhamba kanye namanye amaphuzu aphezulu okukhanya okugcwele Izinhlobo zemifino, kufanele ukhethe inetha le-shading enezinga eliphansi le-shading, njengesilinganiso se-shading sika-35% -50%, ukuze uqinisekise ukuthi ukukhanya okukhanyayo ku-50,000 lux.
3. Bheka indaba
Kunezinhlobo ezimbili zezinto zokukhiqiza zamanethi e-sunshade asemakethe njengamanje.Enye i-polyethylene 5000S ene-high-density polyethylene ekhiqizwa amabhizinisi e-petrochemical kanye nokwengezwa kwe-masterbatch yombala kanye ne-anti-aging masterbatch., Isisindo esilula, ukuguquguquka okulingene, indawo ye-mesh ebushelelezi, ecwebezelayo, uhla olukhulu lokulungiswa kwesilinganiso se-shading, 30% -95% ingafinyelelwa, impilo yesevisi ingafinyelela iminyaka emi-4.
Enye yenziwe ngamanethi amadala ase-sunshade asesebenzile kabusha noma imikhiqizo yepulasitiki.Isiphetho siphansi, isandla siqinile, usilika ugqinsile, inetha liqinile, inetha liminyene, isisindo siyasinda, izinga lokuthungatha ngokuvamile liphakeme, futhi linephunga elimnandi, futhi impilo yesevisi ifushane. , eziningi zazo zingasetshenziswa unyaka owodwa kuphela.Ngokuvamile ngaphezu kuka-70%, akukho ukupakisha okucacile.
4. Qaphela kakhulu lapho uthenga amanetha e-sunshade ngesisindo
Manje kunezindlela ezimbili zokuthengisa amanetha e-sunshade emakethe: enye iyindawo, kanti enye ngesisindo.Amanetha athengiswa ngesisindo ngokuvamile amanetha agaywa kabusha, futhi amanetha athengiswa ngendawo ngokuvamile aba amanetha amasha.
Abalimi bemifino kufanele bagweme amaphutha alandelayo lapho bekhetha:
1. Abalimi bemifino abasebenzisa amanetha e-shading kulula kakhulu ukuthenga amanetha anezinga eliphezulu le-shading lapho bethenga amanetha e-shading.Bazocabanga ukuthi amazinga aphezulu e-shading apholile.Kodwa-ke, uma izinga le-shading liphezulu kakhulu, ukukhanya eshedini kubuthakathaka, i-photosynthesis yezitshalo iyancishiswa, futhi iziqu zincane futhi zinemilenze, okunciphisa isivuno sezitshalo.Ngakho-ke, lapho ukhetha inetha le-shading, zama ukukhetha umthunzi ngenani eliphansi le-shading.
2. Uma uthenga amanetha e-shading, zama ukukhetha imikhiqizo evela kubakhiqizi abakhulu nemikhiqizo enemikhiqizo eqinisekisiwe, futhi uqinisekise ukuthi imikhiqizo enewaranti yeminyaka engaphezu kwengu-5 isetshenziswa ku-greenhouse.
3. Izici zokuncipha kokushisa kwenetha le-sunshade azinakwa kalula yiwo wonke umuntu.Ngonyaka wokuqala, i-shrinkage iyona kakhulu, cishe ngo-5%, bese kancane kancane iba yincane.Njengoba iyancipha, izinga le-shading liyanda.Ngakho-ke, izici zokuncipha ezishisayo kufanele zicatshangelwe lapho kulungiswa nge-slot yekhadi.
Isithombe esingenhla ukudabuka kwenetha le-sunshade okubangelwa ukuncipha kokushisa.Uma umsebenzisi esebenzisa isikhala sekhadi ukuze asilungise, uziba isici sokuncipha kokushisa futhi akasigodli isikhala sokuncipha, okuholela ekutheni inethi ye-sunshade ilungiswe iqine kakhulu.
Kunezinhlobo ezimbili zezindlela zokumboza inetha le-shading: ukumbozwa okugcwele kanye nokufakwa kohlobo lwe-pavilion.Ekusetshenzisweni okungokoqobo, ukumbozwa kohlobo lwe-pavilion kusetshenziswa kakhulu ngenxa yomphumela wayo ongcono wokupholisa ngenxa yokujikeleza komoya okubushelelezi.Indlela eqondile yile: sebenzisa uhlaka lwamathambo eshede le-arch ukumboza inetha lomthunzi welanga phezulu, bese ushiya ibhande lokungenisa umoya elingama-60-80 cm kulo.Uma imbozwe ngefilimu, inetha le-sunshade alikwazi ukumbozwa ngokuqondile efilimu, futhi igebe elingaphezu kuka-20 cm kufanele lishiywe ukuze kusetshenziswe umoya ukupholisa.
Ukumboza inetha lomthunzi kufanele kwenziwe phakathi kuka-10:00 ekuseni no-4:00 ntambama, ngokuya ngezinga lokushisa.Lapho izinga lokushisa lehla laya ku-30 ​​℃, inethi yomthunzi ingasuswa, futhi akufanele imbozwe ngezinsuku eziguqubele ukuze kuncishiswe imiphumela emibi emifino..
