Muaj ntau hom khoom haum rau lub tsev cog khoom siv hluav taws xob nce qhov teeb meem ntawm kev xaiv.
Yuav kom tsis txhob yuam kev thiab tsis tau them nyiaj ntxiv, nws yog ib qho tseem ceeb uas yuav tsum to taub qhov nta ntawm cov lus xaiv.
Hom ntaub ntawv npog
Qhov feem ntau yog cov nram qab no hom ntaub npog rau greenhouses thiab greenhouses: polyethylene thiab reinforced film, iav thiab nonwovens. Tsis tas li ntawd, ntawm kev muag khoom tuaj yeem nrhiav tau npog muaj ntau lawm.
Luam yeeb yaj kiab
Lub ntsiab kom zoo dua ntawm kev siv fais fab - siab zog ntawm tus nqi siv tau thaum kaw lub ru tsev ntawm lub tsev cog khoom. Ua raws li, cov yeeb yam muaj zog muaj peb txheej: ob txheej txheej ntawm polyethylene los yog polypropylene, thiab ib qho ntxiv rau hauv nruab nrab.
Rau qhov kev txhawb zog ntawm zaj duab xis yog siv fiberglass. Nrog ib tug thickness ntawm txog 0.2-0.3 mm, fiberglass mesh ntse withstands feem ntau ntawm cov yam ntxwv ntawm kev siv ntawm kev siv nyob rau hauv kev struts. Yog li, cov yeeb yaj kawv muaj peev xwm ua haujlwm tau los ntawm qhov ntsuas kub ntawm -50 txog +60 degrees, tsis muaj cua hlob txog li 30 meters ntawm ib nrab. lub teeb kis thaum tau txais kev cawmdim ntawm 75%.
Xaiv ib zaj yeeb yaj kiab rau ib lub tsev cog qoob loo, koj yuav tsum faj txog cov ntsiab lus hauv qab no:
- xim Cov kab xiav daj lossis xiav yog zoo dua tsis siv hauv vaj npas. Xws li cov qauv no tsis yog qhov zoo tshaj plaws, los yog npaj rau kev tsim ua. Cov tsos kob zoo yog dawb los sis xiav;
- ceev. Rau teb cov kev xaiv zoo tshaj plaws yog los ntawm 120 mus rau 200 g / m2.
Qhov yeeb yaj kiab tshiab yog muag ntawm 15-20 m. Dav - txog 2 mus rau 6 m.
Polyethylene
Polyethylene zaj duab xis rau lub tsev cog qoob los sis lub tsev cog qoob loo thaum lub sijhawm ntawd cov ntaub ntawv uas pheej yig tshaj plaws kev ua lag luam. Qhov no yog tiav los ntawm yooj yim ntawm chaw ua khoom siv. Polyethylene muaj ib theem siab lub teeb kis (80-90%)Txawm li cas los, nws muaj me ntsis mechanical zog.
TSEEM CEEB! Qhov loj tshaj plaws kev puas ntsoog ntawm polyethylene tshwm sim nyob rau ntawm lub crease ntawm creases. Tus kws sau paj lug yuav tsum tsis txhob siv li 180 degrees.
Nyob rau hauv horticulture, feem ntau siv yas zaj duab xis nrog ib tug tuab ntawm 0.08-0.1 mm, uas, nrog rau kev siv, ntse ua haujlwm tawm ib lossis ob lub caij. Muaj kev xaiv denser, tab sis lawv yog cov kim dua.
Nonwovens
Nonwoven npog khoom rau greenhouses - agrotextiles xa mus rau cov ntaub ntawv vim lub peculiarities ntawm kev tsim technology. Nws essence tuaj mus rau melting polypropylene, tshuab tshuab polypropylene nyias nyias thiab tsevneeg ua ke. Txoj kev sib txuas rau ntau lub tuam txhab yuav txawv dua, tab sis ntawm cov zis lawv tau txais tib yam nkaus li: ib daim ntaub ua los ntawm cov hluav taws xob cog ruaj ruaj.
Lub ntsiab zoo nonwovens:
- qhov loj mechanical zog thiab ua haujlwm ntev;
- muaj peev xwm tsis nco tsis yog hnub ci tawg, tab sis kuj ya raws;
- dav dav. Agrotextiles muaj nyob rau hauv ntom ntawm 17, 30, 40 thiab 60 g / m2.
Tsis tas li, nonwovens tej zaum yuav txawv xim:
- - dawb, coj tus nqi qis tshaj thiab ceev. Lawv siv los tiv thaiv tawm tsam lig Frost, shading nroj tsuag nyob rau hauv lub tshav kub, zoo li cov khoom siv rau ib ntus greenhouses;
- - tsaus (tsaus ntsuab, xim av lossis xim dub). Feem ntau feem ntau muaj qhov ceev ntawm 40-60 g / sq.m. Vim yog lub peev xwm ntawm qhov chaw tsaus nti kom sov li ntawm lub hnub ci tsis muaj zog, greenhouses los ntawm cov khoom no yog indispensable rau loj hlob thaum ntxov seedlings. Tsis tas li ntawd, tsaus agrofabric yuav kaw lub txaj thiab pristvolny voj voog ntawm cov ntoo nyob rau hauv thiaj li tiv thaiv tawm tsam weeds.
Iav
Lub keeb kwm ntawm kev siv cov iav rau cov hnub nyoog hauv greenhouses rov qab mus rau cov kev sim ntawm agrotechnical ntawm Peter I. Cov iav iav muaj qhov zoo li hauv qab no:
- - yuav luag tsis txhob ncua cov ultraviolet uas yuav tsum tau siv rau cov nroj tsuag;
- - muaj kev ntseeg zoo rau kev rhuav tshem;
- - tsis txhob hloov lawv lub cev thiab cov duab geometric qhov kub thiab txias.
Txawm li ntawd los, nyob rau hauv tam sim no tsev xog paj ntawm iav nyob rau hauv teb yog tsis tshua siv. Qhov no yog vim tus nqi siab ntawm cov ntaub ntawv nws tus kheej thiab qhov yuav tsum tau tsim kom muaj zog thav plaub nyob rau hauv nws. Txwv kev siv thiab kev raug mob ntawm cov iav tawg.
Npog
Kev siv npog npog rau greenhouses tsim ntau cov amenities rau gardener:
- - khov kho stitched npog rau lub tsev cog khoom yuav kav ntev mus ntau xyoo;
- - Muaj ntau lub qhov rais tswj cov nroj tsuag ntawm cov nroj tsuag thiab nyob rau hauv qee zaus tshem tawm qhov yuav tsum tau tshem tawm cov tsev cog khoom thaum nruab hnub;
- - yooj yim fixture cia koj mus securely txhim kho cov khoom nyob rau hauv lub thav duab.
Qhov tsis zoo muaj npog - lawv tus nqi siab. Tsis tas li ntawd, cov npog li feem ntau muaj qee qhov ntau thiab tsawg, ua rau nws nyuaj rau lawv siv rau ntawm cov qauv uas tsis yog tus qauv.
Lwm cov ntaub ntawv
Raws li cov ntaub npog, cov yeeb yaj kiab thiab cov khoom siv yuav siv tau los ntawm ntau lub hnub ci hluav taws xob. Yog li ntawd, gardeners feem ntau muaj greenhouses nrog coatings xws li:
- - polycarbonate (ntawm cev thiab cov monolithic). Nws muaj ib lub qis xwb, khaws cov cua kub zoo, thiab nyob ze rau qhov iav uas zoo tib yam rau lub teeb ci. Txawm li cas los xij, xws li panels yuav hloov cov geometry thaum rhuab. Vim li no, lawv xav tau kev xav mus kom txog thaum nruab ntiag tug;
- - acrylic, zoo dua lub npe hu ua plexiglass lossis plexiglass. Tuab yeem muaj peev xwm khoov tau tom qab cua sov thiab tom qab tswj xyuas qhov zoo lawm, cia koj los tsim cov greenhouses ntawm cov thawj cov teeb meem. Qhov tsis zoo yog tias nws yog yooj yim scratched, uas impairs lub teeb kis;
- - fiberglass. Muaj fiberglass puag thiab hluavtaws. Muaj peev xwm ntawm nws tus kheej tsim fiberglass panels. Cov khoom yog muaj zog heev thiab ruaj, tab sis sai sai.
Koj tuaj yeem saib xyuas ntau hom ntaub ntaiv thiab lawv cov khoom siv hauv kev yees duab:
Npog li cas?
Yuav kom sai sai thiab tau txais txiaj ntsim zoo ntawm lub tsev cog khoom, koj yuav tsum ua tib zoo nyeem cov qauv ntawm cov khoom npog xaiv thiab coj lawv mus rau hauv tus account thaum lub sij hawm ua haujlwm. Qhov no tso cai rau qhia tag nrho cov kev xav ntawm lub txheej thiab tsis tsim kev puas tsuaj rau thaum lub caij teeb tsa.
Kom ua kom yooj yim thiab ua kom yooj yim rau cov txheej txheem, koj yuav tsum ua tib zoo saib xyuas cov ntsiab lus hauv qab no:
- - ua ntej pib siv npaj ib qho kev npaj qhia ntxiv;
- - Koj yuav tsum muab ua ntej khoom txaus nrog qee qhov paj tau paj;
- - lub thav duab ntawm lub tsev xog paj yuav tsum nrog Tshuag tswj qhov hnyav npog cov ntaub ntawv.
Txij li feem ntau cov tsev cog qoob loo tsis txawv hauv kev siv zog, nws yuav tsum ua hauj lwm nrog lawv zoo heev.
Kev siv lub tsev cog qoob rau ntawm koj tus kheej lub cev nrog koj tus kheej tes yog ib qho kev tshwm sim muaj rau txhua tus liaj ua teb nrog cov kev txawj hauv kev tsim kho. Yuav kom ua tiav, nws yog ib qho zoo tsim nyog rau kev kawm ua ntej cov lus qhia ntau tshaj plaws txog kev ua teb ua teb.
