I-Red Shade Net yoKhuseleko lweZityalo

Umthunzi Obomvu Umnatha woKhuseleko lweZityalo uMnatha oFakelweyo

inkcazelo emfutshane:

I-Shading net, ekwabizwa ngokuba yi-shading net, luhlobo olutsha lwezixhobo ezikhethekileyo zokugquma ezikhusela ezolimo, ukuloba, ukufuya izilwanyana, ukukhuselwa ngumoya, kunye nokugquma komhlaba okuthe kwakhuthazwa kule minyaka ili-10 idlulileyo.Emva kokugubungela ehlotyeni, idlala indima ekuthinteleni ukukhanya, imvula, i-moisturizing kunye nokupholisa.Emva kokugubungela ebusika nasentwasahlobo, kukho ukugcinwa kobushushu obuthile kunye nomphumo wokufuma.
Ehlotyeni (Juni ukuya ku-Agasti), owona msebenzi uphambili wokugubungela umnatha we-sunshade kukuthintela ukuvela kwelanga elitshisayo, impembelelo yemvula enkulu, ubungozi bobushushu obuphezulu, kunye nokusasazeka kwezinambuzane kunye nezifo, ngakumbi ukuthintela ukuvela kwemvula enkulu. ukufuduka kwezinambuzane.
I-sunshade net yenziwe nge-polyethylene (i-HDPE), i-polyethylene ephezulu, i-PE, i-PB, i-PVC, izinto ezisetyenzisiweyo, izinto ezintsha, i-polyethylene propylene, njl. njengezinto eziluhlaza.Emva kwe-UV stabilizer kunye ne-anti-oxidation unyango, lunamandla okuqina okuqinileyo, ukuxhathisa ukuguga, ukuxhathisa ukubola, ukuxhathisa kwimitha, ukukhanya kunye nezinye iimpawu.Isetyenziswa kakhulu ekulinyweni kokukhusela imifuno, amaqunube anevumba elimnandi, iintyatyambo, umngundo otyiwayo, izithole, izinto zonyango, iginseng, iGanoderma lucidum kunye nezinye izityalo, kunye nakumashishini okuzala amanzi kunye neenkukhu, kwaye ineziphumo ezicacileyo ekuphuculeni imveliso.

Indima ye-sunshade net:
(1) Umthunzi, ukupholisa kunye nokufumisa Okwangoku, izinga lomthunzi weemanetha zomthunzi eziveliswe 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 izinga lokushisa lomoya langaphandle lifikelela kwi-35-38 ° C, uluhlu oluqhelekileyo lokupholisa lunokufikelela kwi-9-13 ° C, kwaye ukuhla okuphezulu kunokuba yi-19.9 ° C.Isiphumo sokupholisa esicacileyo siphezu komhlaba, silandelwa nguluhlu lwama-20 cm ngaphezulu nangaphantsi komhlaba, kunye noluhlu lwe-5 cm ngaphezulu nangaphantsi kwamagqabi esityalo.Ukugubungela umnatha welanga ehlotyeni elishushu, ubushushu bomphezulu bunokuhla nge-4-6°C, ubuninzi bunokufikela ku-19.9°C, ubushushu obuyi-30 cm ngaphezu komhlaba bunokuthotywa nge-1°C, kunye nobushushu be-5. cm ngaphantsi komhlaba kunokuthotywa ngo-3-5 ° C;ukuba umphezulu ugqunyiwe, iqondo lobushushu eliyi-5 cm ngaphantsi komhlaba lingathotywa.
Emva kokuba umnatha we-shading ugutyungelwe, i-radiation yelanga iyancipha, ubushushu bomhlaba buyancipha, isantya somoya siyancipha, kunye nokunyuka komswakama womhlaba kuyancipha.Ngokubanzi, ubushushu bungama-30% ukuya kuma-40% kuphela kwindawo evulekileyo, enemisebenzi ecacileyo yokuthintela imbalela kunye nokufumisa.
(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.

3. Ukukhethwa kwempahla ye-sunshade net
1. Izinga lomthunzi: Ukukhethwa kwereyithi yomthunzi womnatha womthunzi kufuneka kuthathelwe ingqalelo ngokupheleleyo le miba ilandelayo: uhlobo lwegreenhouse, imathiriyeli yokugquma igreenhouse, iimeko zemozulu zasekuhlaleni, kunye neentlobo zezityalo zegreenhouse.Ngokukodwa iimfuno zokukhanya zeentlobo zezityalo, indawo yembuyekezo yokukhanya kunye nendawo yokukhanya ye-photosynthesis yezityalo ezahlukeneyo zahlukile kwinqanaba ngalinye lokukhula.Emva kokuqwalaselwa ngokupheleleyo kwemiba emininzi, obona bukhulu bokukhanya bufanelekele isityalo kufuneka buthelekiswe ngokupheleleyo kwaye oyena unoqoqosho kakhulu kufuneka kukhethwe., Umnatha womthunzi onengqiqo.
Iindidi kunye nemisebenzi ye-shading inetha kwii-greenhouses zilungele ukukhetha kwakho ukutyala kwezolimo ehlotyeni

Isiphumo sokupholisa: Phantsi kweemeko zokuqinisekisa iimfuno zokukhanya zokukhula kwesityalo, okukhona ukusasazeka kwemitha yelanga kubonakaliswa ngumnatha wesunshade, kokukhona isiphumo sokupholisa singcono.Ngexesha lokupholisa kwe-shading yangaphakathi, inxalenye yemitha yelanga ebonakalisiweyo iya kuthatyathwa ngumnatha we-shading ngokwayo, okukhokelela ekunyuseni kweqondo lokushisa lomnatha we-shading kunye nokutshintshana kobushushu kunye nomoya wangaphakathi, ngaloo ndlela kwandisa ubushushu be-greenhouse. .Ngoko ke, ukuze ufumane isiphumo esihle sokupholisa sokupholisa ngaphakathi, umnatha okhethiweyo we-shading kufuneka ube nokubonakala okuphezulu kwimitha yelanga.Ngokubanzi, ifoyile ye-aluminium kwi-mesh ye-aluminium foil ine-reflection ephezulu kwimitha yelanga, kwaye umphumo wokupholisa uphezulu kakhulu kunezinye iintlobo ze-meshes.Umphumo wokupholisa we-sunshade wangaphandle unokungayinaki inxalenye yamandla athathwe ngumnatha we-sunshade ngokwawo, ngoko ke umphumo wokupholisa we-sunshade wangaphandle unqunywe ngokubanzi ngumlinganiselo we-shading.

Ngaphambili: Isiphumo esihle se-shading net kwizityalo zemifuno ukunciphisa ukukhanya kunye nomoya
