Leej twg xav tau xav txog kaum xyoo tas los lawm tias peb yuav muaj feem xyuam rau txoj kev loj hlob thiab kev sib koom ntawm vaj thiab vaj cog qoob loo nrog kev pab ntawm cov xim gamut ntawm tsev cog khoom npog tsev?
Ntxiv nrog rau kev tu ncua. xaiv cov xim polycarbonate kom yog kom loj hlob muaj zog nroj tsuag thiab tsim txoj cai rau high school yield.
Cia peb sim paub seb qhov xim ntsuab polycarbonate zoo li cas siv rau lub tsev cog khoom.
Kev tshawb nrhiav
Hnub ci yog tsim nyog rau cov nroj tsuag kom loj hlob, dais thiab muaj me tub. Qhov no peb paub los ntawm lub tsev kawm ntawv cov lus qhia ntawm botany. Kev ua tiav lub hnub ci hauv lub tsev cog khoom yog tsis yooj yim sua, vim hais tias tej ntug kev cas absorbs qee yam ntawm nws.
Yog nws ua tau kom npog lub tsev cog khoom nrog xim polycarbonate? Nws yog ib txwm ntseeg hais tias cov ntaub ntawv rau npog greenhouses yuav tsum raws li pob tshab li sai tau.
Tsis ntev los no, tab sis, gardeners tau nce pib siv cov xim polycarbonate rau lub hom phiaj no, thaum xaiv daj, txiv kab ntxwv thiab xim liab. Vim li cas thiaj xaiv polycarbonate rau greenhouses? Qhov xim zoo tshaj plaws yog dab tsi?
Nyhuv ntawm cov xim rau cov nroj tsuag
Yuav ua li cas xim ntawm polycarbonate yog zoo dua rau xaiv rau lub tsev xog paj? Lub teeb spectrum nruab nrab yog electromagnetic tsis muaj ntau qhov ntev. Ib txhia ntawm lawv ua rau cov nroj tsuag puas tsuaj, lwm tus - zoo.
Txhua yam nws yog nyob ntawm seb qhov no los yog lub teeb ntawd yog absorbed los ntawm chlorophyll - ib qho ntawm cov neeg tseem ceeb nyob hauv photosynthesis. Qhov ntsuas ntawm qhov ntsuas electromagnetic wavelength yog ntsuas hauv nanometers (nm).
280 nm wavelength yog tawv ultraviolet, nws yog pom tsis tau rau peb ob lub qhov muag thiab muaj qhov tsis zoo rau tib neeg thiab cov nroj tsuag. Nws nthe nplooj, loj hlob ntsiab lus tuag. Qhov zoo ntawm polycarbonate yog tias nws ua kom absorbbs cov rays.
Ultraviolet ib feem ntawm lub spectrum nrog lub wavelength ntawm 280 mus rau 315 nm contributes rau lub hardening ntawm cov nroj tsuag thiab nce lawv tsis kam mus txias. Electromagnetic tsis nyob hauv thaj tsam ntawm 315-380 nm txhim kho cov metabolism thiab txhawb kev loj hlob. Polycarbonate tsis nco qab cov kab mob ultraviolet.
Ntsuab spectrum yuav luag tsis tau los ntawm cov nroj tsuag, txawm tias qhov tseeb hais tias nws yog nyob rau hauv "ntsuab" (550 nm) tias qhov siab tshaj plaws ntawm lub nrig spectrum ntawm tshav ntuj ntaus nqi los ntawm lub qhov muag. Ua nyob rau hauv tus ntawm no xim, cov nroj tsuag pib wither, qeeb hauv txoj kev loj hlob thiab ncab.
Ntxoov ntawm ntshav-xiav (380 - 490 nm) yog qhov tseem ceeb rau txoj kev loj hlob thiab kev loj hlob. Violet xim muaj feem xyuam rau kev tsim cov proteins thiab kev loj hlob tus nqi ntawm cov nroj tsuag. Nyob rau hauv xws li ib spectrum, nws yog ib qho zoo kom loj hlob cov qoob loo ntawm ib hnub luv luv, lawv tawg sai dua.
Xim xim lig ntxim rau ntawm kev loj hlob ntawm ntsuab loj - lub qia thiab nplooj. Yog tias lub hawj xiav ntawm lub spectrum tsis tau nyob hauv lub tsev cog khoom teeb pom kev zoo, cov nroj tsuag tuaj yeem pib rub kom ntseeg tau nws cov koob ntawm lub teeb.
Rau cultivation ntawm txiv hmab txiv ntoo cov qoob loo pom yog qhov ntau ntawm cov txiv kab ntxwv (620-595 nm) thiab liab (720-600 nm) xim. Lawv feem ntau nquag absorbed los ntawm cov duab xim - chlorophyll thiab ua rau kom muaj kev tsim cov roj carbon monoxide. Qhov hluav taws xob no muab cov nroj tsuag nrog lub zog rau photosynthesis, thiab cuam tshuam qhov nqi ntawm txoj kev loj hlob.
Polycarbonate Transparency
Kev xaiv ntawm polycarbonate hnub no nws tsis tshua muaj dav, thiab raws li qhov muaj peev xwm ntawm nws daim ntawv thov. Ntawm cov yam ntxwv ntawm cov khoom, lub teeb kis tau plays lub luag hauj lwm tseem ceeb, tshwj xeeb tshaj yog thaum siv los ua ib txheej rau greenhouses.
Polycarbonate yog cov khoom yooj yim thaum coated. lub teeb kis ntawm lub qhov muag los ntawm khoov vojvoog thiab qee zaum ntawm 82 mus txog 90%.
Matt colored polycarbonate yuav tsis ua hauj lwm. kom npog greenhouses, nws cia tsawg dua 65% ntawm lub hnub lub rays. Feem ntau nws yog siv rau cov sheds qhov ntxoov ntxoo yog qhov xav tau.
Transparent polycarbonate kuj nyob ntawm qhov tuab ntawm daim ntawvuas yuav ua tau los ntawm 4 mus txog 25 hli. Lub thicker cov khoom, tsawg lub teeb nws conducts. Rau greenhouses, ib tug tuab ntawm 4 mus rau 16 mm yog pom zoo. Qhov kev xaiv nyob ntawm seb hom tsev cog khoom.
Tsev cog khoom, raws li ib tug dai kom zoo ntawm lub dacha
Tsev xog paj ntawm dawb lias polycarbonate nws tus kheej twb yog ib qho kev nthuav qhia. Ib lub ci nqaij ntawm cov dacha zaub ntsuab yeej pleases lub qhov muag.
Yog hais tias koj xav tau ib qho kev tsim kho, koj tuaj yeem cog nroj zais tsaws ncig ntawm nws thiab tso tawm ib txoj hau kev zoo nkauj rau lub tsev cog khoom.
Rau decorating greenhouses los ntawm tsis-coloured pob zeb polycarbonate siv tau daim duabyog hais tias lub tsev cog khoom khov yog qhia rau lub cuab yeej.
Nws yog ua tau rau thov daim duab tsuas yog rau qhov no ntawm lub tsev cog khoom. Lub ru tsev thiab sab phab ntsa yuav tsum tau ceev kom tsis txhob ua kom nws qhov chaw sab hauv.
Diam duab
No nyob hauv cov duab muaj cov piv txwv ntawm cov xim ntsuab thiab cov greenhouses nrog tus qauv.
Polycarbonate yuav luag supplanted khob, raws li ib tug dacha, thiab muaj greenhouses.
