Ngokuphuculwa kwengeniso yokutyala kwezibonelelo ezinkulu ze-cherry kwiindawo zokugcina izityalo, indawo yokutyala kwiindawo ezahlukeneyo iyaqhubeka nokukhula;nangona kunjalo, kwiminyaka yakutshanje, imbalela kunye nemvula encinane kukhokelele kumaqondo obushushu aphezulu ehlotyeni, kunye neeyure zokukhanya ezinde zibangele ukwanda kweziqhamo ezinkulu ze-cherry ezikhubazekileyo (amawele okanye i-multiples), echaphazela isivuno semithi yeziqhamo;ngexesha elifanayo Ngenxa yokuba iziqhamo kunye nemifuno zandisa iindleko zabasebenzi.Iimvavanyo zifumene ukuba xa ukukhanya kokukhanya kufikelela kwi-100,000 LUX okanye ngaphezulu, kwaye ubushushu be-ambient bufikelela kuma-degrees angama-35 kwiiyure ze-5 iintsuku eziliqela ezilandelelanayo, iziganeko zeziqhamo ezikhubazekileyo zanda kakhulu;ifomu.Ke ngoko, kwixesha elingevayo ngamaqondo obushushu bokwahlulo lwentyatyambo, ukuba ubushushu obuphezulu kakhulu bufunyenwe, imilinganiselo enjengokugquma umphezulu womthi ukwenzela ukufihlwa kwexesha elifutshane ukunciphisa ubushushu kunye nobushushu bemitha yelanga kunokunciphisa ngempumelelo ukwenzeka kwepistil ephindwe kabini. iintyatyambo, ngaloo ndlela kuncitshiswa ukukhubazeka kunyaka olandelayo.ukwenzeka kweziqhamo.Ukusetyenziswa kweminatha yomthunzi ukuthoba kunye nokupholisa amatsheri amakhulu kwindawo yokusebenzela ibe yinto ekufuneka yenziwe rhoqo ehlotyeni.Ehlotyeni, ukuze kuthintelwe imiqobo yobushushu obuphezulu, amafama eziqhamo kunye nemifuno asoloko esebenzisa indlela yomthunzi ukunciphisa ubushushu kwishedi.Kwimveliso yangempela, iindlela ezahlukeneyo zokuthungatha zisetyenziswa, ezinye zigqunywe ngamanetha omthunzi omnyama kunye nesilivere-grey ukupholisa, kwaye ezinye zigalelwa ngodaka kunye ne-inki kwifilimu yokuchitha ukuze kuphole.Ezi ndlela zahlukeneyo zokuthunga ngokuqinisekileyo zineempembelelo ezahlukeneyo ze-shading.
Ukhetho lwenzululwazi kunye nolunengqiqo lweminatha ye-sunshade
Umsebenzi ophambili weshading inethakukuthintela ukukhanya okuqinileyo kunye nokunciphisa ubushushu be-greenhouse.Nangona kunjalo, ukuba ukhetha umnatha ongafanelekanga womthunzi, awuyi kubangela ukuba izityalo zikhule ngomlenze, kodwa zibuye zingathandeki kwientyantyambo kunye neziqhamo.Ke ngoko, isikrini kufuneka sikhethwe ngokwesayensi nangengqiqo.
1. Musa ukugweba i-pros and cons of shade shade by color: iminatha yomthunzi okwangoku kwimarike ngokuyinhloko imnyama kunye nesiliva-grey.Umnatha womthunzi omnyama unomlinganiselo ophezulu we-shading kunye nokupholisa ngokukhawuleza, kwaye ufanelekile ukugubungela ixesha elifutshane kwiinkalo ezifuna ukulawulwa ngokucophelela ehlobo elishushu;umnatha wesiliva-grey umthunzi unomlinganiselo ophantsi we-shading kwaye ufanelekile kwimifuno ethanda ukukhanya kunye nokugubungela ixesha elide.
2. Umgangatho womnatha we-sunshade awunqunywanga ngumbala, umbala we-sunshade net wongezwa kwinkqubo yokwenziwa kwezinto eziluhlaza.Ngoko ke, imifuno eyahlukileyo kufuneka ikhethe iinethi ze-shading ngemibala eyahlukeneyo kunye namazinga ahlukeneyo omthunzi.Ngokomzekelo, itumato sisityalo esithanda ukukhanya.Ngethuba nje idibana nexesha lokukhanya kwelanga kwiiyure ezili-11 ukuya kwi-13, izityalo ziya kukhula ngamandla kwaye ziqhakaze ngaphambili.Nangona umphumo wexesha lokukhanya kwiitamatato ungabalulekanga kangako, ukukhanya okukhanyayo kuhambelana ngqo nesivuno kunye nomgangatho.Ukukhanya okungonelanga ngokulula kunokukhokelela ekungondleki, ukukhula okunemilenze, kunye nokuncipha kweentyatyambo.Indawo yokugcwalisa i-tomato yi-70,000 lux, kwaye indawo yembuyekezo yokukhanya yi-30,000-35,000 lux.Ngokubanzi, ukukhanya kokukhanya emini ehlotyeni yi-90,000-100,000 lux.
3. Umnatha omnyama we-shading inezinga eliphezulu lomthunzi ukuya kuma-70%.Ukuba i-black shading net isetyenzisiwe, ukukhanya okukhanyayo akukwazi ukuhlangabezana neemfuno eziqhelekileyo zokukhula kwetamatato, ekulula ukubangela i-tomato enemilenze kunye nokuqokelela okwaneleyo kweemveliso ze-photosynthetic.Uninzi lweminatha yesiliva-grey shade inezinga le-shading ye-40% ukuya kwi-45%, kunye nokuhanjiswa kokukhanya kwe-40,000 ukuya kwi-50,000 lux, enokuthi ihlangabezane neemfuno eziqhelekileyo zokukhula kwetamatato.Ngoko iitumato zigqunywe kakuhle ngeminatha yomthunzi wesilivere-grey.
4. Ukuze kuphunyezwe amazinga ahlukeneyo e-shading, umnatha ngamnye womthunzi unobunzima obuhlukeneyo bokuluka.Kukho iindidi ezintathu ngokubanzi;izinga lomthunzi weenaliti ezimbini ngu-45%;iinaliti ezintathu ziyi-70%;kunye neenaliti ezine ngama-90%.Ngoko ke, xa ukhetha umnatha womthunzi, umnatha womthunzi welo xinzelelo kufuneka ukhethwe ngokwezityalo ezityaliweyo.
Ngokweempawu zokukhula kwe-cherry enkulu, ukukhanya kwayo kufana nokukhula kwejinja, ngoko kuyacetyiswa ukuba kusetyenziswe i-2-inaliti yomthunzi.
Ziphephe iimpazamo ezilandelayo xa ukhetha:
1. Abalimi beziqhamo abasebenzisa iinethi ze-shading zilula kakhulu ukuthenga iinethi ezinamazinga aphezulu omthunzi xa kuthengwa iminatha ye-shading.Baya kucinga ukuba amazinga aphezulu e-shading apholile.Nangona kunjalo, ukuba izinga le-shading liphezulu kakhulu, ukukhanya kwi-shed ibuthathaka, i-photosynthesis yezityalo iyancitshiswa, kwaye iziqu zincinci kwaye zincinci, ezinciphisa isivuno sezityalo.Ngoko ke, umnatha we-sunshade kufuneka ukhethwe ngokokukhanya kwezityalo ezityalwayo.
2. Iimpawu zokunciphisa ukushisa komnatha we-sunshade zihoywa lula ngumntu wonke.Ngomnyaka wokuqala, i-shrinkage iyona nto ininzi, malunga ne-5%, kwaye ngokuthe ngcembe iba yincinci.Njengoko iyancipha, izinga le-shading liyanda.Ngoko ke, iimpawu zokunciphisa i-thermal kufuneka ziqwalaselwe xa kulungiswa nge-slot yekhadi.
