I-Q1: Ngaba inani lokuthunga umgangatho wokuthengaumnatha womthunzi?

Impendulo 1: Xa uthenga, kufuneka uqale uqinisekise ukuba ingaba sisikhuseli elangeni ngocingo olungqukuva okanye isikhuseli elangeni ngocingo olusicaba.Ucingo locingo olujikelezileyo lwe-sunscreen lufana nomgca wentlanzi, kwaye ucingo olusicaba lukwimilo yeshiti.

Ucingo oluqhelekileyo olucabasunshade netinokuthengwa ngokwenani le-stitches kunye nereyithi ye-shading.Ngokomzekelo, kwi-sunshade yeenaliti ezintathu ezifanayo, ubuninzi be-50% ye-sunshade kunye ne-70% ye-sunshade iyahluka.Ngokuphathelele i-sunshade net ene-70% yezinga le-sunshade, ukuba iinaliti ezi-3 zithelekiswa neenaliti ezi-6, iinaliti ezi-6 ziya kubonakala zixinene.Ngoko ke, inani lokuthunga kunye nesantya se-shading kufuneka zidibaniswe xa kuthengwa.

Ngokuqhelekileyo, i-mesh ye-sunshade yocingo ejikelezileyo ininzi yezikhonkwane ezi-6, ezifuna ukukhethwa kuphela ngokwezinga le-shading.Ezinye i-aluminium foil sunshades, i-black-and-white sunshades, njl. ngokuqhelekileyo ziyi-6-pin, kwaye abalimi bemifuno banokukhetha ngokwezinga le-shading.

I-Q2: I-sunshade ethengwe kwiqonga le-Intanethi iphawulwe njenge-3-pin.Emva kokufumana iimpahla, kuncinci kakhulu kunemifanekiso, kwaye ayikwazi ukufezekisa umphumo oyifunayo we-sunshade.Indlela yokuphepha le ngxaki?

A2: Ngokuqhelekileyo, ixabiso le-sunshade liqulunqwe ngezinto kunye neenkqubo.Ukuba ixabiso le-sunshade ye-pin emithathu lingaphantsi kwe-1 yuan / imitha yesikwere, kufuneka ikhethwe ngokucophelela.Xa uthenga kwi-intanethi, zama ukukhetha uphawu oluthembekileyo, okanye ukhethe itshaneli yokuthengisa enegunya lokuthengisa, ukwenzela ukuba uqinisekise umgangatho.

I-Q3: Uthini umahluko phakathi kwe-sunscreen emnyama kunye nesilivere yesiliva, kunye nendlela yokuyisebenzisa?

I-A3: I-sunshade emnyama inomlinganiselo ophezulu we-sunshade kunye nokupholisa ngokukhawuleza, kodwa into engalunganga kukuba kufuneka itsalwe kwaye ibekwe yonke imihla.Akunakugqunywa yonke imini ukuphepha ukubunjwa kwendawo yokukhanya ebuthathaka kwi-shed, echitha ixesha kwaye inzima.I-black sunshade net kufuneka isetyenziselwe ukugquma okwexeshana kwizityalo zegreenhouse ezifuna ukulawulwa ngononophelo ehlotyeni.

Isilivere engwevu i-shading inezinga eliphantsi lomthunzi, kodwa ilungile kwaye inokugqunywa imini yonke.Kufanelekile ngakumbi kwimifuno enothando olukhanyayo kwiindawo zokugcina izityalo kunye neendawo zokugcina izityalo ezifuna ukugcinwa kwexesha elide.

Nangona kunjalo, kungakhathaliseki ukuba luhlobo luni lwe-sunscreen olusetyenziswayo, la manqaku mabini alandelayo kufuneka athathelwe ingqalelo: 1. Ixesha lokugubungela kunye nobude.2. Ukungabikho kokukhanya okunamandla kunye nokushisa okuphantsi, i-sunshade ayikwazi "ukulala" kwi-greenhouse yonke ixesha.Amandla okukhanya kunye namaqondo obushushu afunwayo ziimeko zemozulu, iintlobo zezityalo kunye namaxesha ahlukeneyo okukhula kwezityalo aya kulawulwa ngokuguquguqukayo xa i-sunshade net ingagqunywanga.

Xa ubeka umnatha we-sunshade, umnatha we-sunshade unokuxhaswa ukwenza ibhande lokungenisa umoya, kunye ne-sunshade kunye nefuthe lokupholisa kuya kuba ngcono.Kwi-sunscreen yangaphandle esetyenziselwa inkxaso, kuyafuneka kwakhona ukuqwalasela ukuba i-shrinkage ye-thermal ye-sunscreen izinzile.Ukuba i-thermal shrinkage ayizinzanga, inokubangela umonakalo kwi-bracket kunye ne-slot, okanye ikrazule i-sunscreen.Ukuba awuqinisekanga ukuba ukushwabana kobushushu kuzinzile, ungazama kwindawo encinci kuqala

Ukongezelela, ukuba i-shrinkage ye-thermal inkulu kakhulu, izinga le-shading yelanga liya kwanda emva kwexesha lokusetyenziswa.Izinga le-shading ye-shading net ayilona likhulu ngakumbi.Ukuba izinga lomthunzi liphezulu kakhulu, i-photosynthesis yezityalo iya kuncitshiswa kwaye iziqu ziya kuba zincinci.

I-Q4: Ungathenga njani kwaye usebenzise i-sunscreen emnyama namhlophe?

Impendulo yesi-4: I-sunshade emnyama namhlophe yenziwe ngamacala amnyama namhlophe.Xa ugubungela, icala elimhlophe lijonge phezulu.Xa kuthelekiswa nomnyama, umphezulu omhlophe omhlophe unokubonakalisa ukukhanya kwelanga (kunokuba uyithintele), ongcono kunomnyama kwisiphumo sokupholisa.Umphezulu ophantsi omnyama unomphumo we-shading kunye nokupholisa, okwandisa izinga le-shading ngaphezu kwayo yonke i-white shading net.Iipores phakathi komnatha ziqinisekisa izinga eliphezulu lokungena komoya kunye nehlabathi langaphandle, kunye nokuphucula ukunikezelwa kwe-oksijini yezityalo kwindawo yokutyala.Umthunzi welanga owenziwe nge-high-high-high-high-high umsonto wefilament fiber unomgangatho ophezulu kunye nobomi benkonzo ende.Lukhetho olufanelekileyo kwi-greenhouse ye-fungus edliwayo, i-chrysanthemum kunye nezinye izityalo ezithintekayo ekukhanyeni.

I all white shading net, esetyenziswa kakhulu kwizithole ze strawberry nasekutyaleni, inokuthintela ukukhula kwezityalo.Isenokusasazwa ngaphezulu kwefilimu ye-mulch ukwahlula iziqhamo zequnube kwifilimu ye-mulch, ukunciphisa ukwenzeka kweziqhamo ezibhakiweyo, iziqhamo ezibolileyo kunye nokungunda okungwevu, kunye nokuphucula izinga lempahla yorhwebo.

I-Q5: Kutheni kukho umgama othile phakathi komnatha we-shading yangaphandle kunye nezixhobo zokugubungela ezifana nefilimu ye-greenhouse, ukwenzela ukuba umphumo wokupholisa ube ngcono?Ngowuphi umgama ofanelekileyo?

A5: Kuyacetyiswa ukuba kugcinwe umgama oyi-0.5 ~ 1m phakathi komnatha we-sunshade kunye nomgangatho weshedi.Umoya ophakathi komnatha we-sunshade kunye neshedi ungahamba, nto leyo enokukhawulezisa ilahleko yobushushu kwishedi.Isiphumo sokupholisa i-sunshade singcono.

Ukuba umnatha we-shading usondele kwifilimu ye-greenhouse, ubushushu obubanjwe ngumnatha we-shading bunokudluliselwa lula kwifilimu ye-greenhouse kwaye emva koko kwi-greenhouse, kwaye umphumo wokupholisa ubi.Ngokusondeleyo kwifilimu ye-greenhouse yenza ukushisa akukwazi ukuchithwa, ukwandisa ukushisa kwayo, ngoko kuya kukhawulezisa ukuguga.Ngoko ke, xa usebenzisa i-sunscreen, qiniseka ukuba ugcine umgama ofanelekileyo kwifilimu ye-greenhouse.Ungasebenzisa ucingo lwentsimbi ukuxhasa umnatha we-sunshade okanye ilaphu le-sunshade ngokuthe ngqo ngaphezulu kwe-greenhouse.Abalimi bemifuno ngaphandle kweemeko banokubeka iingxowa zomhlaba kwisakhelo esiphambili se-greenhouse, kwaye bafake amakhethini engca phambi kwe-greenhouse ngexesha le-3 ~ 5 yeemitha, ukwenzela ukuba umnatha we-shading ungasondeli kwifilimu ye-greenhouse.
