Njengoba ukukhanya kuba namandla futhi izinga lokushisa likhuphuka, izinga lokushisa eshede liphakeme kakhulu futhi ukukhanya kunamandla kakhulu, osekuyisici esiyinhloko esithinta ukukhula kwezilimo.Ukunciphisa izinga lokushisa kanye namandla okukhanya eshedeni,ama-shading amanethakukhona ukukhetha kokuqala.Nokho, abalimi abaningi basanda kubika ukuthi nakuba izinga lokushisa liye lehla ngemva kokusebenzisa inetha le-sunshade, izitshalo zinezinkinga zokukhula okubuthakathaka kanye nesivuno esincane.Ngemva kokuqonda okuningiliziwe, umhleli ukholelwa ukuthi lokhu kubangelwa izinga eliphezulu le-shading enetha le-sunshade elisetshenzisiwe.Kunezizathu ezimbili eziyinhloko zezinga eliphezulu le-shading: enye inkinga yendlela yokusebenzisa;enye inkinga ye-sunshade net uqobo.Ngokusebenzisa amanetha e-sunshade, izici ezilandelayo kufanele zinakwe:
Okokuqala, kufanele sikhethe inetha elifanele le-sunshade.
Imibala yamanethi anomthunzi emakethe ikakhulukazi emnyama kanye nesiliva-grey.Okumnyama kunezinga eliphezulu lokufiphaza kanye nomthelela omuhle wokupholisa, kodwa kunomthelela omkhulu ku-photosynthesis.Ilungele ukusetshenziswa ezitshalweni ezithanda umthunzi.Uma isetshenziswa ezitshalweni ezithanda ukukhanya Isikhathi sokuhlanganisa kufanele sincishiswe.Nakuba inetha elinomthunzi ompunga esiliva lingasebenzi kahle ekupholiseni njengaleli elimnyama, linomthelela omncane ku-photosynthesis yezitshalo futhi lingasetshenziswa ezitshalweni ezithanda ukukhanya.
Okwesibili, sebenzisa inetha le-sunshade ngendlela efanele.
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.Nakuba ukumboza inetha le-sunshade kunganciphisa izinga lokushisa, futhi kunciphisa amandla okukhanya, okunomthelela omubi ku-photosynthesis yezitshalo.Isevisi yezobuchwepheshe bezolimo ye-Tianbao (ID: tianbaotsnjfw) Ngakho-ke, isikhathi sokumboza sibaluleke kakhulu, futhi kufanele sigwenywe usuku lonke.Ukumboza kwenziwa ngokwezinga lokushisa eliphakathi kuka-10:00 am no-4:00 ntambama.Lapho izinga lokushisa lehla laya ku-30 ​​°C, inethi yomthunzi ingasuswa, futhi ayimbozwa ngezinsuku eziguqubele ukuze kuncishiswe umthelela omubi ezitshalweni.
Ucwaningo luphinde lwathola ukuthi inkinga yenetha le-shading ngokwayo nayo iyisici esingenakunakwa esibangela ukuthi izinga le-shading libe phezulu kakhulu.Njengamanje, kunezinhlobo ezimbili eziyinhloko zamanetha e-sunshade emakethe: eyodwa ithengiswa ngesisindo, kanti enye ithengiswa ngendawo.Amanethi athengiswa ngesisindo ngokuvamile amanethi asetshenziswa kabusha, angamanethi ekhwalithi ephansi futhi anempilo yesevisi yezinyanga ezi-2 ukuya onyakeni ongu-1.Leli netha libonakala ngocingo oluwugqinsi, inethi eqinile, ukuhwalala, anezikhala eziminyene, isisindo esisindayo, kanye nezinga lokufiphaza eliphakeme ngokuvamile.Ngaphezulu kuka-70%, awekho amaphakheji acacile.Amanethi athengiswa ngendawo ngokuvamile awamanethi abalulekile amasha, anempilo yesevisi yeminyaka emi-3 kuya kwemi-5.Leli netha libonakala ngesisindo esilula, ukuguquguquka okumaphakathi, indawo enetha ebushelelezi futhi ecwebezelayo, kanye nohlu olubanzi lokulungiswa kwezinga le-shading, okungenziwa kusuka ku-30% kuya ku-95%.fika.
Lapho uthenga inetha le-shading, kufanele siqale sinqume ukuthi izinga le-shading liphakeme kangakanani eshedini lethu.Ngaphansi kokukhanya kwelanga ehlobo, amandla okukhanya angafinyelela ku-60,000-100,000 lux, kuyilapho izitshalo, indawo yokukhanya ekhanyayo yemifino eminingi i-30,000-60,000 lux, njengephuzu le-pepper light saturation liyi-30,000 lux, isitshalo seqanda singama-40,000 we-lux cucumber. ingu-55,000 lux.
Ukukhanya okudlulele kuzoba nomthelela omkhulu ku-photosynthesis yezitshalo, okuholela ekumunceni kwe-carbon dioxide evinjiwe kanye nokuphefumula okukhulu kakhulu.Lesi yisenzo se-photosynthetic "ikhefu lasemini" esenzeka ngaphansi kwezimo zemvelo.Ngakho-ke, ukusetshenziswa kwesembozo senetha le-shading ngesilinganiso esifanele se-shading akukwazi nje ukunciphisa izinga lokushisa ngaphambi nangemva kwasemini, kodwa futhi kuthuthukise ukusebenza kahle kwe-photosynthetic yezitshalo, ukubulala izinyoni ezimbili ngetshe elilodwa.
Ngokucabangela izidingo zokukhanyisa ezihlukene zezitshalo kanye nesidingo sokulawula izinga lokushisa leshede, kufanele sikhethe inetha le-shading elinezinga elifanele le-shading.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 okugcwala ukukhanya Ezinhlotsheni zezitshalo, kufanele ukhethe inetha le-shading enezinga eliphansi le-shading, njengezinga le-shading lika-35-50%, ukuqinisekisa ukuthi ukukhanya okukhanyayo ku-50,000 lux.
