Ukukhethwa kweemanetha ze-shading zomthunzi kunye nezityalo ezithanda ukukhanya zihluka kakhulu

Kwimarike, kukho imibala emibini ye-sunshade: emnyama kunye nesiliva engwevu.Umnyama unezinga eliphezulu lomthunzi welanga kunye nesiphumo esihle sokupholisa, kodwa kunempembelelo enkulu kwi-photosynthesis.Ifaneleka ngakumbi kwizityalo ezithanda umthunzi.Ukuba isetyenziswa kwizityalo ezithanda ukukhanya, ixesha lokhuselo kufuneka lincitshiswe.Nangona impembelelo yokupholisa yesilivere engwevu ye-shading net ayilunganga njengaleyo ye-black shading net, inempembelelo encinci kwi-photosynthesis yezityalo kwaye inokusetyenziswa kwizityalo ezithanda ukukhanya.

Sebenzisa ngokuchanekileyo i-sunscreen ukunciphisa ubushushu kunye nokunyusa ukukhanya

Kukho iindlela ezimbini zokugubungela i-sunshade: ukugubungela ngokupheleleyo kunye nohlobo lwe-pavilion.Kwisicelo esisebenzayo, uhlobo lwe-pavilion lunesiphumo esingcono sokupholisa ngenxa yokujikeleza komoya ococekileyo, ngoko ke isetyenziswa rhoqo.

Iindlela ezikhethekileyo zezi:

Sebenzisa amathambo eshedi ukogquma umnatha we-sunshade phezulu, ushiye ibhanti lokungenisa umoya elingama-60-80cm ngaphezulu.

Ukuba ifilimu ihlanganiswe, i-sunscreen ayinakugubungela ngokuthe ngqo kwifilimu, kwaye isithuba esingaphezu kwama-20 cm kufuneka sishiywe ukuze sipholile ngomoya.

Nangona ukugubungela ishading inethainokunciphisa ubushushu, ikwanciphisa ukukhanya, okunefuthe elibi kwiphotosynthesis yezityalo.Ke ngoko, ixesha lokugquma libaluleke kakhulu.Kufuneka kuphephe ukugubungela imini yonke.Inokugqunywa phakathi kwe-10 am kunye ne-4pm ngokweqondo lobushushu.Xa amaqondo obushushu ehla ukuya kuma 30 ℃, umnatha womthunzi unokususwa, kwaye akufuneki ugqunywe ngeentsuku ezinamafu ukunciphisa ifuthe elibi kwizityalo.

Xa sithengaiminatha ye-sunshade,kufuneka siqale sicacise ukuba uphezulu kangakanani izinga lomthunzi welanga kwishedi yethu.

Ngaphantsi kwelanga elithe ngqo ehlotyeni, ukukhanya kokukhanya kunokufikelela kwi-60000 ukuya kwi-100000 lux.Kwizityalo, indawo yokuzalisa ukukhanya kwimifuno emininzi yi-30000 ukuya kwi-60000 lux.Umzekelo, indawo yokugcwala kwepepile yi-30000 lux, eye-eggplant yi-40000 lux, kwaye leyo yecucumber yi-55000 lux.

Ukukhanya okugqithisileyo kuya kuba nefuthe elikhulu kwi-photosynthesis yezityalo, okukhokelela ekufunxeni okuvaliweyo kwekharbon diokside, ukuphefumla okugqithisileyo, njl.

Ngoko ke, ukusebenzisa iminatha yomthunzi ngesantya esifanelekileyo somthunzi akunakunciphisa kuphela iqondo lobushushu kwishedi malunga nasemini, kodwa nokuphucula ukusebenza kakuhle kwe-photosynthetic yezityalo, ukubulala iintaka ezimbini ngelitye elinye.

Ukuqwalasela iimfuno zokukhanyisa ezahlukeneyo zezityalo kunye nesidingo sokulawula ukushisa kwe-shed, kufuneka sikhethe umnatha we-shading kunye nesantya esifanelekileyo somthunzi.Akufunekanga sibawele ixabiso eliphantsi kwaye sikhethe ngokwentando yethu.

Kwi-pepper ene-low saturation point, i-shading net enezinga eliphezulu le-shading ingakhethwa, umzekelo, izinga le-shading ngu-50% ~ 70%, ukwenzela ukuba kuqinisekiswe ukuba ukukhanya kokukhanya kwi-shed malunga ne-30000 lux;Kwizityalo ezinendawo ephezulu ye-isochromatic saturation yekhukhamba, umnatha we-shading enezinga eliphantsi lomthunzi kufuneka ukhethwe, umzekelo, izinga lomthunzi kufuneka libe yi-35 ~ 50% ukuqinisekisa ukuba ukukhanya kokukhanya kwi-shedi yi-50000 lux.
