Cov neeg ua haujlwm hauv lub caij ntuj sov, thiab cov pib tshiab hauv kev lag luam no, tej zaum paub tias nws nyuaj npaum li cas los saib xyuas lub vaj. Cov qoob loo, cov hnub ci thiab cov kab mob tua tau ntau qhov ntawm cov qoob loo yav tom ntej, yog li qhov teeb meem ntawm nws txoj kev txuag yog qhov tseem ceeb. Piv txwv li, koj puas paub dab tsi los npog lub txaj tiv thaiv lawv ntawm qhov tsis zoo ntawm thaj chaw? Tsis yog? Tom qab ntawd cov tshooj no yog rau koj.
Polyethylene zaj duab xis
Cov khoom nto moo tshaj plaws thiab ntev ntev yog cov yas yeeb yaj kiab. Qhov twg tsis yog siv: nyob hauv txhua txhua hnub, kev lag luam thiab txawm tias thaum lub caij ua haujlwm dacha-gardening, vim nws tau ntev lub ntsiab ntaub ntawv tsim kom muaj lub tsev cog khoom (txawv versions ntawm xws li ib tug movie muaj txawv zog).
Piv txwv, nyob rau hauv cov khoom siv ntawm lub teeb ci-stabilized, UV teeb-stabilizer ntxiv rau nws muaj pes tsawg leeg, uas pab tiv thaiv polymer txheej ntawm cov teebmeem ntawm lub hnub. Lub sijhawm theem ntawm cov khoom siv no yog txiav txim los ntawm tus nqi ntawm cov stabilizer ntxiv. Tsis tas li ntawd, lub dye yog feem ntau ntxiv rau zaj duab xis, uas muaj peev xwm hloov lub spectrum ntawm tshav ntuj.
Nws tseem ceeb heev! Lub tshuab zaj duab xis polyethylene tau khaws kub kom zoo thiab khaws ya raws tsis muaj kev cuam tshuam cov qauv thiab lub zog ntawm cov av. Tsis tas li ntawd, ua tsaug rau nws, nws tswj kom tiv thaiv cov av los ntawm kev ntxuav tawm chiv, uas txhais tau hais tias tus sau yuav ntxov.
Ib qho tseem ceeb heev ntawm qhov sib txawv ntawm daim npog no dub thiab dawb zaj duab xis, nyob rau hauv uas ib sab yog dub thiab lwm yam yog dawb. Nws yog qhov zoo rau siv nyob rau hauv greenhouses, qhov twg nws yog them nrog lub ntiaj teb nrog dawb sab li, uas muaj txhawb rau lub xav txog ntawm tshav ntuj tshaj. Nyob rau tib lub sij hawm, sab sab black tsis pub cov nroj tsuag mus rau germinate nruab nrab ntawm noj qab haus huv cov qoob loo.
Lub uniqueness ntawm yas zaj duab xis nyob rau hauv kev tsim kho ntawm greenhouses yog manifested nyob rau hauv ib theem siab ntawm lub zog thiab tsis kam mus rau mechanical kev nyuaj siab. Nws yog ib qho ua tau kom ua tau zoo li no siab npaum li cas ntawm kev siv vim tshwj xeeb kev tsim khoom siv rau kev siv ntawm cov khoom, thaum siv cov khoom siv moj khaum tso rau hauv ib zaj duab xis peb txheej nruab nrab ntawm cov khaubncaws sab nraud povtseg.
Cov qauv ntawm cov yeeb yam yees duab kuj tseem muaj xws li UV stabilizers, uas cia kom tsis txhob sib npaug sib npaug ntawm lub hnub, tab sis kuj mus cuag lub neej ntawm tus yeeb yam nws tus kheej. Vim yog qhov tseeb, nws yog qhov nrov nrov nce.
Koj puas paub? Polyethylene yog ib qho kev tshawb nrhiav pom tias German engineer Hans von Pechmann ntsib 1899.
Ntawm lwm qhov zoo ntawm polyethylene zaj duab xis, nws yog tsis yooj yim sua kom tsis paub qhov sib txawv ntawm lub teeb pom kev zoo muaj peev xwm, kev muaj peev xwm khaws hluav taws kub thiab tiv thaiv los ntawm cov nroj tsuag Frost thiab nag lossis daus.
Nyob rau tib lub sijhawm rau tsis zoo ntawm daim ntawv thov yuav tsum muaj cov kev lag luam tsuas yog ua nrog cov ncej thaij, tsis muaj peev xwm ua rau cov dej thiab cua txias (koj yuav tsum muaj dej thiab cua txias, uas nce nqi zog) thiab yuav ua rau cov kab mob nroj tsuag, uas yog vim muaj kev txav ntawm cov txheej txheem ntawm cov yeeb yaj kiab.
Tsis tas li ntawd, tom qab los nag, yog tias cov dej txaws rau ntawm nws, zaj duab xis yuav zoo. Feem ntau qhov nruab nrab polyethylene khoom yog txaus rau ib lub caij, tab sis koj tuaj yeem sim ua ntev nws txoj hauj lwm lub neej los ntawm kev tshem tawm, ntxuav thiab ua kom zoo zoo kom qhuav ua ntej lub caij nplooj dacha tom ntej.
Non-Woven Polypropylene Fibre
Nonwoven npog cov khoom rau txaj (xws li rau lub caij ntuj no) - Qhov no yog ib qho khoom noj khoom haus zoo tshaj, cov khoom uas muaj cov iav polypropylene uas yog glued hauv qaug siab. Externally, cov khoom uas tsis yog-cov ntaub ntawv zoo ib yam li cov yeeb yaj kiab uas yog polyethylene, tab sis lawv cov yam ntxwv zoo tseem txawv.
Ua ntej Cov khoom no yog ntau sib zog thiab softer tshaj polyethylene, thiab lawv tuaj yeem npog cov nroj tsuag uas tsis muaj kev them nyiaj yug, tsuas yog ntuav cov nplooj ntoo saum toj kawg nkaus. Tsis tas li ntawd, qhov sib piv zoo dua yog qhov kev muaj peev xwm los hla dej thiab cua, ua tsaug uas nws yog ua tau rau dej nroj tsuag yam tsis tau tshem lawv lub cover.
Nyob ntawm theem ntawm kev ceev, non-woven polypropylene fiber tau muab faib ua ob peb hom:
- 17-30 g / m2 - cov khoom siv uas tuaj yeem tiv thaiv tau cov ntoo ntawm lub qhov qhib ntawm lub hnub ci thiab lub caij nplooj ntoos hlav hmo ntuj, thiab cov dej zoo, cov huab cua thiab lub teeb, ua ke nrog cov thermal conductivity, pab nroj tsuag kom tsim tau cov kev zoo tshaj plaws rau lawv txoj kev loj hlob thiab kev loj hlob.
Lwm qhov tsis zoo ntawm kev siv cov khoom siv no ua ib lub tsev rau ib lub tsev cog qoob loo yog qhov zoo ntawm kev tiv thaiv cov noog thiab kab. Ua tsaug rau cov khoom siv no nrog ib ntu ntawm 17-30 g / sq.m, lawv kuj them zaub, bushes, berries, txiv hmab txiv ntoo thiab nroj tsuag ornamental, uas nyob rau hauv feem ntau loj hlob on qhib av.
- 42-60 g / sq.m - Nws yog qhov zoo tshaj plaws nyob rau hauv rooj plaub uas qhov kev tsim kho ntawm ib lub tsev cog qoob loo uas tau npaj, thiab nws yog ib qhov tsim nyog muab lub caij ntuj no rau cov nroj tsuag.
- 60 g / m2 - ntom non-woven khoom "rau tub nkeeg", cov kev pab ntawm kev siv uas tag nrho them rau nws tus nqi lag luam.
Nyob rau theem ntawm cov tsis muaj fiber ntau polypropylene fiber, qee cov tuam txhab tau ntxiv rau hauv nws cov qoob loo ntawm UV stabilizer tsim los txhawb lub neej ntawm cov khoom.Qhov ntxiv ntawm carbon dub muab cov nonwovens ib xim dub uas pab kom nqus hnub ci, yog li ntawd cov nroj tsuag hauv vaj tse tau txais ntau tshaj cua sov, thiab cov nroj tsuag muab zais los ntawm lub hnub tuag sai sai.
Feem ntau, cov khoom siv dub yog feem ntau yog siv cov mulch, thiab dawb ncav mus rau ntawm cov ntoo kom tiv thaiv lub vaj. Cov qauv ntawm cov khoom tso cai rau nws mus zoo kawg dhau dhau noo noo, yog li dej thiab daim ntawv thov ntawm cov kua chiv tsis yog nyuaj.
Nyob rau theem ntawm cov tsis muaj fiber ntau polypropylene fiber, qee cov tuam txhab tau ntxiv rau hauv nws cov qoob loo ntawm UV stabilizer tsim los txhawb lub neej ntawm cov khoom.Ntawm ntau yam ntawm nonwoven npog cov ntaub ntawv qhia hnub no nws yog qhov nyuaj heev los xaiv ib qho kev xaiv. Txawm li cas los, tsis txhob hnov qab qhov ntawd lub essence ntawm tag nrho cov ntawm lawv yog yuav luag tib yam, thiab cov kev sib txawv dag tsuas yog nyob rau hauv proprietary production technologies thiab, ntawm chav kawm, nyob rau hauv nqe.
Qhov kev xaiv nrov tshaj plaws hauv kev lag luam hauv domestic yog spunbond (non-woven khoom ua los ntawm polymer yaj spunbond), uas nws lub npe tau los ua ib lub tsev neeg rau npe npog khoom.
Yog li, nws yog qhov nyuaj rau cov tswv ntawm lub dacha thaj av ua ib qho kev txiav txim siab: spunbond los yog agrospan (nonwoven npog cov khoom nrog ib lub neej txuas ntxiv).
Npog khoom mulch
Mulch npog khoom (los sis tsuas yog "mulch") - Qhov no yog cov khoom organic los yog cov khoom tsim, uas yog feem ntau siv los ua teb rau.
Organic xaiv nws yog qhov sib txawv los ntawm kev sib xyaw rotting, raws li qhov tshwm sim ntawm cov av tau muab nrog cov tshuaj muaj txiaj ntsim (nws cov yam ntxwv zoo tuaj thiab hloov acidity). Xav txog kev hloov hauv cov tshuaj tiv thaiv hauv cov av, cov av hu ua organic yuav tsum siv nrog kev saib xyuas huab.
Nyob rau tib lub sijhawm inorganic mulching khoom uas tuaj yeem hais nyob rau hauv daim ntawv ntawm pob zeb, slate, gravel, crushed pob zeb, granite thiab marble chips, nyob rau hauv tas li ntawd mus rau lub ntsiab tseem ceeb, kuj ua tau zoo nkauj ua haujlwm.
Raws li mulch nyob rau hauv lub vaj teb feem ntau siv dub thiab xim zaj duab xis, uas muaj peev xwm yuav ua ke nrog zoo nkauj plantings.
Ntawm chav kawm, tsuas yog thaum muaj kev sib xyaw ua ke nrog cov khoom siv organic thiab inorganic mulch (piv txwv, kev sib tov zoo ua rau cov khoom siv hauv qab thiab daim tawv ntoo saum toj no) koj tuaj yeem tau txais txiaj ntsig zoo tshaj.
Feem ntau, mulching agrofibre hais txog cov ntaub ntawv uas tsis yog-woven polypropylene, uas, txawm tias tsis tsim kev puas tsuaj rau cov neeg, tsiaj txhu thiab nroj tsuag lawv tus kheej, tsis txhob cia txhua sij hawm rau cov nroj tsuag tuag los ntawm ib tug tsis muaj lub teeb. Qhov ceev ntawm no hom "ntaub" (rau lub tsev xog paj yog siv heev tsis) yog 50-60 g / sq.m.
Tus qauv ntawm daim ntawv thov mulch npog cov ntaub ntawv yog raws li nram no: tau tos kom txog rau thaum cov av dries tawm tom qab lub caij ntuj no, nws yuav tsum tau npaj rau cog. Tom qab ntawd, dub agrofibre yog kis thoob plaws hauv txaj, uas yuav tsum tiv thaiv kom txhob germination ntawm weeds.
Cov tub ntxhais hluas seedlings ntawm tseem ceeb cov qoob loo yog cog nyob rau hauv cruciform slits, yav tas los tsim nyob rau hauv ib daim ntawv npog siv tej yam khoom tawm. Yog li, ob qho tib si pib xyaum ua gardeners thiab cov neeg ua liaj ua teb uas koom rau hauv cov txiv hmab txiv ntoo thiab zaub zaub txuag lawv tus kheej los ntawm kev siv cov tshuaj herbicides hauv kev tswj cov nroj tsuag.
Nyob rau hauv tas li ntawd, koj tsis xav kom ploj mus ntev heev nyob rau hauv lub dacha thaj av, siv ntau ntawm kev rau siab on weeding lub zaub teb. Yuav tsis muaj cov nroj tsuag ntawm nws, thiab kev noj qab haus huv cov qoob loo loj hlob nyob rau hauv txawm kab yuav muaj peev xwm zoo siab nrog koj sai maturation.
Strawberries feem ntau yog cog rau ntawm mulch npog cov khoom. Nws yog yooj yim dua kom loj hlob nws li no, vim hais tias peb lub xyoos koj tsis tau xav txog cog hloov, thiab lub weeds yog tsawg dua.
Nws tseem ceeb heev! Raws li kev xyaum qhia, lub ntiaj teb nyob rau hauv zaj duab xis tseem tshuav ntau friable tshaj nyob rau hauv cov khoom uas tsis yog-woven.Nws yog ib qho yooj yim los piav qhia txog qhov tshwm sim no: thaum lub sij hawm lub caij ntuj nag, txawm tias ib tug txiv hmab txiv ntoo loj hlob rau tej yam khoom tsis yog khoom noj absorbs ntau dua li ntawm av. Nws hloov tawm tias nws loj hlob zuj zus sai tshaj li qhov qub. Ntxiv mus, tag nrho loj qoob loo tseem tshua huv.
Polycarbonate
Polycarbonate txheej - qhov zoo tshaj plaws lwm txoj rau ib zaj duab xis rau vaj tse ntawm greenhouses. Cov khoom no yuav tiv thaiv tau txhua yam nroj tsuag ntawm nag, cua thiab cov kab mob, tsim kev zoo rau kev loj hlob thiab kev loj hlob ntawm cov khoom noj qab haus huv. Yeej tseem zoo Polycarbonate yog ib daim ntawv yas, muaj sab hauv kab noj hniav, ib yam dab tsi zoo xws li qag "honeycomb". Nws yog ib qho sib zog dua li cov khoom tsim thiab tsis muaj qhov ntxhiab tsw ntxhiab, thiab cov ntawv txheeb cais los ntawm kev siab zog.
Koj puas paub?Piv nrog rau iav, ib daim ntawv ntawm cellular polycarbonate nyhav 16 npaug dua, thiab yog tias muab piv nrog acrylic, nws qhov hnyav yuav peb zaug tsawg dua.Nws tseem yog qhov yuav tsum tau nco ntsoov qhov tsis kam ua kom hlawv thiab qhov zoo heev ntawm cov khoom siv no, thiab cov pob tshab polycarbonate kuj tuaj yeem xa tawm mus txog 92% ntawm tshav ntuj txoj kab. Feem ntau, thaum tsim cov ntawv txheeb polycarbonate, UV stabilizers raug ntxiv rau qhov sib xyaw kom haum, uas tsuas ua rau lub neej ua hauj lwm ntawm cov khoom tau piav qhia.
Kev tsim qauv ntawm cov xaum ntawv uas muaj niaj hnub no muaj cov ntsiab lus hauv qab no: 2.1 x 2 m, 2.1 x 6 m thiab 2.1 x 12 m, thiab lawv cov thickness yuav txawv ntawm 3.2 hli mus rau 3.2 cm.
Yog tias koj xav tau polycarbonate kaj lug, los yog koj xav tau ntau dua lub suab qis, nyob rau hauv txhua rooj plaub, koj yuav tsis muaj teeb meem nrog kev xaiv, vim cov tuam txhab niaj hnub no muaj kev ncaj ntau palette ntawm ntxoov.
