Umsebenzi wei-aluminiyam ye-sunshade net:
(1) Ukugcinwa komthunzi, ukupholisa kunye nokugcinwa kobushushu.Okwangoku, izinga lomthunzi weminatha yomthunzi oveliswe kwilizwe lam yi-25% ukuya kwi-75%.Iminatha yomthunzi wemibala eyahlukeneyo ineendlela ezahlukeneyo zokuhambisa ukukhanya.Umzekelo, ukuhanjiswa kokukhanya kweinetha ezimnyama ze-shading ziphantsi kakhulu kunesilivere-grey shading networks.Ngenxa yokuba umnatha we-shading unciphisa ukukhanya kokukhanya kunye nobushushu obukhanyayo bokukhanya, kunesiphumo esicacileyo sokupholisa, kwaye ukuphakama kwamaqondo obushushu angaphandle, kucacile ngakumbi umphumo wokupholisa.Xa ubushushu bomoya wangaphandle bufikelela kuma-35-38°C, izinga lokupholisa ngokubanzi lingancitshiswa ukuya kuthi ga kwi-19.9°C.Ukugquma inethi yomthunzi welanga ehlotyeni kushushu kunokunciphisa ubushushu bomphezulu nge-4 ukuya kwi-6 °C, kwaye ubuninzi bunokufikelela kwi-19.9 °C.Emva kokuba umnatha we-sunshade ugqunyiwe, imitha yelanga iyancipha, ubushushu bomhlaba buyehla, isantya somoya siba buthathaka, kunye nokunyuka komphunga wokufuma komhlaba kuyancipha, okunokumelana okucacileyo nembalela.Umsebenzi wokukhusela ukufuma.
(2) Ukumelana nomoya, ukuthintela imvula, ukukhuseleka kwezifo kunye nezinambuzane Umnatha we-shading unamandla amakhulu omatshini, onokucothisa ilahleko yemifuno ebangelwa yinkanyamba, imvula, isichotho kunye nezinye imozulu embi.I-greenhouse igqunywe ngumnatha womthunzi.Ngexesha lesaqhwithi, isantya somoya ngaphakathi kwishedi simalunga ne-40% kuphela yesantya somoya ngaphandle kweshedi, kwaye umphumo wokuthintela umoya uyabonakala.I-plastichouse greenhouse egqunywe ngomnatha we-shading inokunciphisa impembelelo yemvula emhlabeni ukuya kwi-1/50, kwaye imvula kwishedi ingancitshiswa nge-13.29% ukuya kwi-22.83%.Umnatha osilver-grey sunshade unesiphumo esicacileyo sokunqanda iintwala kwaye unokunciphisa ngempumelelo ukusasazeka kunye nokusasazeka kweentsholongwane.Ukugubungela igumbi lomnatha ngomnatha womthunzi kunokuthintela umonakalo wezinambuzane zangaphandle kunye nezifo.Ngokovavanyo lwe-tomato yasekwindla, kunye nesigqubuthelo somthunzi wesiliva-grey, iziganeko zesifo sentsholongwane yezityalo yi-3%, kwaye i-60% ayigqunywanga.
(3) I-antifreeze kunye nokugcinwa kobushushu Ukuze kuphuculwe izinga lokusetyenziswa kwenethi yomthunzi kunye nokunciphisa iindleko zokugquma, inokusetyenziselwa ukuthintela iqabaka ekuqaleni kokwindla, ukuthintela iqabaka emva kwexesha entlakohlaza kunye nokuthintela ukonakala kweqabaka ebusika. .Kufunyaniswe ukuba umnatha womthunzi wesilivere-ngwevu unokunyusa ubushushu bomphezulu nge-1.3 ukuya kwi-3.1 °C ebusuku.
