imikhiqizo

Indima yenethi ye-sunshade:
(1) Ukufiphaza, ukupholisa nokuthambisa Njengamanje, izinga lokuthungatha amanetha omthunzi akhiqizwa ezweni lami lingama-25% kuya ku-75%.Amanetha omthunzi emibala ehlukene anokudlulisa ukukhanya okuhlukile.Isibonelo, ukudluliswa kokukhanya kwamanetha amnyama e-shading kuphansi kakhulu kunamanetha e-silver-gray shading.
Ngenxa yokuthi inetha le-shading linciphisa ukukhanya kokukhanya kanye nokushisa okukhazimulayo kokukhanya, linomphumela wokupholisa osobala, futhi uma izinga lokushisa liphezulu langaphandle, umphumela wokupholisa usobala kakhulu.Lapho izinga lokushisa lomoya wangaphandle lifinyelela ku-35-38°C, izinga lokupholisa elivamile lingafinyelela ku-9-13°C, futhi ukwehla okukhulu kungaba ngu-19.9°C.Umphumela wokupholisa osobala kakhulu ungaphezulu, kulandelwa ububanzi obungama-20 cm ngaphezulu nangaphansi komhlaba, kanye nobubanzi obungama-5 cm ngaphezulu nangaphansi kwamaqabunga esitshalo.Ukumboza inetha le-sunshade ehlobo elishisayo, izinga lokushisa elingaphezulu lingehliswa ngo-4-6°C, eliphakeme lingafinyelela ku-19.9°C, izinga lokushisa libe ngu-30 cm ngaphezu komhlaba lingehliswa ngo-1°C, futhi izinga lokushisa libe ngu-5. cm ngaphansi komhlaba kungehliswa ngo-3-5 ° C;uma ingaphezulu limboziwe, izinga lokushisa elingu-5 cm ngaphansi komhlaba lingehliswa Nciphisa ngo-6 kuya ku-10°C.
Ngemva kokuba inetha le-shading limboziwe, imisebe yelanga iyancipha, izinga lokushisa lomhlabathi liyehla, isivinini somoya siba buthaka, futhi ukuhwamuka komswakama wenhlabathi kuncipha.Ngokuvamile, ukuhwamuka kungama-30% kuya ku-40% kuphela wendawo evulekile, enemisebenzi esobala yokuvimbela isomiso kanye nokuthambisa.
(2) Ivikela umoya, ingangenwa yimvula, ingangeni ezifweni kanye nezinambuzane Inetha lokuthungatha linamandla amakhulu emishini, elingabambezela ukulahleka kwemifino okubangelwa isiphepho, isiphepho, isichotho kanye nezinye izimo zezulu ezimbi.
I-greenhouse imbozwe inetha le-shading.Ngesikhathi kunesishingishane, isivinini somoya ngaphakathi kweshede singama-40% kuphela wesivinini somoya ngaphandle kweshede, futhi umphumela wokuvimbela umoya uyabonakala.

3. Ukukhethwa kwe-sunshade net material
1. Izinga lomthunzi: Ukukhethwa kwezinga lokuthungatha kwenethi yomthunzi kufanele kubhekisise ngokugcwele izici ezilandelayo: uhlobo lwe-greenhouse, izinto ezimboza i-greenhouse, izimo zezulu zendawo, kanye nezinhlobo zezitshalo ezibamba ukushisa.Ikakhulukazi izidingo zokukhanya zezinhlobo zezitshalo, indawo yesinxephezelo sokukhanya nendawo yokugcwala ukukhanya kwe-photosynthesis yezitshalo ezahlukene kuhlukile esigabeni sokukhula ngasinye.Ngemva kokucabangela izici eziningi ngokugcwele, ubukhulu bokukhanya obufaneleka kakhulu besitshalo kufanele buqhathaniswe ngokuphelele futhi kukhethwe owonga kakhulu., Inetha lomthunzi elinengqondo.
Izinhlobo nemisebenzi yamanetha e-shading ezindaweni zokugcina izithombo zilungele ukukhetha kwakho ukutshala kwezolimo ehlobo

Umthelela wokupholisa: Ngaphansi kwezimo zokuqinisekisa izidingo zokukhanya zokukhula kwesitshalo, lapho imisebe yelanga iboniswa inethi ye-sunshade, kuba ngcono umphumela wokupholisa.Phakathi nenqubo yokupholisa ye-shading yangaphakathi, ingxenye yemisebe yelanga ebonisiwe izodonswa yinetha le-shading ngokwayo, okuholela ekwandeni kwezinga lokushisa lenetha le-shading kanye nokushintshaniswa kokushisa nomoya wangaphakathi, ngaleyo ndlela kwandise izinga lokushisa le-greenhouse. .Ngakho-ke, ukuze uthole umphumela omuhle kakhulu wokupholisa wokupholisa kwangaphakathi, inetha elikhethiwe le-shading kufanele libe nokubonakala okuphezulu emisebeni yelanga.Ngokuvamile, ucwecwe lwe-aluminium ku-mesh ye-aluminium foil inokubonakala okuphezulu emisebeni yelanga, futhi umphumela wokupholisa uphakeme kakhulu kunalowo wezinye izinhlobo ze-meshes.Umthelela wokupholisa we-sunshade wangaphandle ungaziba ingxenye yamandla emuncwe inethi ye-sunshade ngokwayo, ngakho umphumela wokupholisa we-sunshade wangaphandle ngokuvamile unqunywa izinga lomthunzi.
