Njengoko ukukhanya kusiba namandla kwaye nobushushu bunyuka, iqondo lobushushu kwishedi liphezulu kakhulu nokukhanya kunamandla, nto leyo eye yaba ngowona mba uphambili uchaphazela ukukhula kwezityalo.Ukunciphisa ubushushu kunye nokukhanya okukhanyayo kwishedi,iminatha yomthunzilukhetho lokuqala.Nangona kunjalo, amafama amaninzi kutshanje anike ingxelo yokuba nangona amaqondo obushushu ehlile emva kokusebenzisa i-sunshade net, izityalo zineengxaki zokukhula okubuthathaka kunye nesivuno esiphantsi.Emva kokuqonda okucacileyo, umhleli ukholelwa ukuba oku kubangelwa izinga eliphezulu le-shading ye-sunshade net esetyenzisiweyo.Kukho izizathu ezibini eziphambili zezinga eliphezulu le-shading: enye yingxaki yendlela yokusetyenziswa;enye ingxaki ye-sunshade net ngokwayo.Ukusetyenziswa kweminatha ye-sunshade, le miba ilandelayo kufuneka ithathelwe ingqalelo:
Okokuqala, kufuneka sikhethe umnatha ochanekileyo we-sunshade.
Imibala yeminatha yomthunzi kwimarike ubukhulu becala imnyama kunye nesilivere-ngwevu.Umnyama unezinga eliphezulu le-shading kunye nesiphumo esihle sokupholisa, kodwa sinempembelelo enkulu kwi-photosynthesis.Ilungele ukusetyenziswa kwizityalo ezithanda umthunzi.Ukuba isetyenziswe kwezinye izityalo ezithanda ukukhanya Ixesha lokhuselo kufuneka lincitshiswe.Nangona umnatha womthunzi osilver-grey ungasebenzi kakuhle ekupholiseni njengomnyama, unempembelelo encinci kwi-photosynthesis yezityalo kwaye unokusetyenziswa kwizityalo ezithanda ukukhanya.
Okwesibini, sebenzisa umnatha we-sunshade ngokuchanekileyo.
Kukho iintlobo ezimbini zeendlela zokugubungela umnatha: ukugubungela ngokupheleleyo kunye nohlobo lwe-pavilion.Kwizinto ezisebenzayo, uhlobo lwe-pavilion lusetyenziswa kakhulu ngenxa yesiphumo esingcono sokupholisa ngenxa yokujikeleza komoya.Indlela ekhethekileyo yile: sebenzisa i-skeleton ye-arch shed ukugubungela umnatha we-sunshade phezulu, kwaye ushiye ibhanti yokungena umoya we-60-80 cm kuyo.Ukuba ugqunywe ngefilimu, umnatha we-sunshade awukwazi ukugqunywa ngokuthe ngqo kwifilimu, kwaye umsantsa ongaphezulu kwe-20 cm kufuneka ushiywe ukusebenzisa umoya ukupholisa.Nangona ukugquma umnatha we-sunshade kunokunciphisa ubushushu, kukwanciphisa ukukhanya, nto leyo enefuthe elibi kwiphotosynthesis yezityalo.Inkonzo yobuchwephesha bezolimo ye-Tianbao (ID: tianbaotsnjfw) Ngoko ke, ixesha lokugquma libaluleke kakhulu, kwaye kufuneka liphetshwe imini yonke.Ukugqunywa kwenziwa ngokweqondo lobushushu phakathi kwentsimbi ye-10:00 kusasa kunye neye-4:00 emva kwemini.Xa amaqondo obushushu ehla ukuya kuma-30 °C, umnatha womthunzi unokususwa, kwaye awugqunywanga ngeentsuku ezinamafu ukunciphisa ifuthe elibi kwizityalo.
Uphando luphinde lwafumanisa ukuba ingxaki ye-shading net ngokwayo yinto engenakuhoywa ebangela ukuba izinga lomthunzi libe phezulu kakhulu.Okwangoku, kukho iintlobo ezimbini eziphambili zeenetha ze-sunshade kwiimarike: enye ithengiswa ngobunzima, kwaye enye ithengiswa ngommandla.Iinetha ezithengiswayo ngobunzima zixhaphakile zinetha zezixhobo ezisetyenzisiweyo, ezizinetha ezikumgangatho ophantsi kwaye zinenkonzo yobomi beenyanga ezi-2 ukuya kunyaka omnye.Lo mnatha ubonakaliswe ngocingo olushinyeneyo, umnatha oqinileyo, uburhabaxa, umnatha oshinyeneyo, ubunzima obunzima, kunye nesantya esiphezulu somthunzi ngokubanzi.Ngaphezulu kwe-70%, akukho phakheji ecacileyo.Iinethi ezithengiswa ngokwendawo zidla ngokuba yiminatha yemathiriyeli emitsha, kunye nobomi benkonzo obuyiminyaka emi-3 ukuya kwemi-5.Lo mnatha ubonakaliswe ngobunzima obulula, ukuguquguquka okuphakathi, indawo egudileyo kunye ne-shiny net, kunye noluhlu olubanzi lohlengahlengiso lwe-shading rate, olunokuthi lwenziwe ukusuka kwi-30% ukuya kwi-95%.fika.
Xa kuthengwa umnatha we-shading, kufuneka siqale sinqume ukuba izinga le-shading liphezulu kangakanani kwi-shed yethu.Ngaphantsi kokukhanya kwelanga ehlotyeni, ukukhanya kokukhanya kunokufikelela kwi-60,000-100,000 lux, ngelixa izityalo, indawo yokukhanya yokukhanya kwimifuno emininzi yi-30,000-60,000 lux, njengendawo yokukhanya kwepepper yi-30,000 lux, i-eggplant yi-40,000 lux cucumber. yi 55,000 lux.
Ukukhanya okugqithisileyo kuya kuba nempembelelo enkulu kwi-photosynthesis yezityalo, okukhokelela ekufunxeni kwekharbon diokside kunye nokuphefumla okugqithisileyo.Le yinto ye-photosynthetic "yekhefu lasemini" eyenzeka phantsi kweemeko zendalo.Ngoko ke, ukusetyenziswa kwe-shading net covering kunye nesantya esifanelekileyo se-shading asikwazi ukunciphisa kuphela iqondo lokushisa kwi-shed ngaphambi nangemva kwemini, kodwa nokuphucula ukusebenza kwe-photosynthetic yezityalo, ukubulala iintaka ezimbini ngelitye elinye.
Ukuqwalasela iimfuno zokukhanyisa ezahlukeneyo zezityalo kunye nesidingo sokulawula ukushisa kwe-shed, kufuneka sikhethe umnatha womthunzi kunye nesantya esifanelekileyo somthunzi.Kulabo abanokukhanya okuphantsi kokukhanya okufana nepepper, unokukhetha umnatha we-shading kunye nesantya esiphezulu se-shading, njengesilinganiselo se-shading ye-50% -70%, ukuqinisekisa ukuba ukukhanya kokukhanya kwi-shed malunga ne-30,000 lux;ukhukhamba kunye nezinye iindawo eziphezulu zokugcwala ukukhanya Kwiintlobo zezityalo, kufuneka ukhethe umnatha we-shading kunye nesantya esincinci se-shading, njengezinga le-shading ye-35-50%, ukuqinisekisa ukuba ukukhanya kokukhanya kwi-shed yi-50,000 lux.
