Ntawm qhov ntau niaj hnub chiv, perlite thiab vermiculite tsis nyob rau hauv qhov chaw kawg hauv tsev hauv paj ntoo. Tsis ntev dhau los, tsawg tus neeg paub txog qhov siv cov ntaub ntawv no rau cov laj thawj no, tab sis hnub no koj tuaj yeem yuav cov khoom tau ntawm txhua lub paj.
Txawm tias muaj tseeb hais tias perlite thiab vermiculite rau cov nroj tsuag muaj heev zoo sib xws, qhov txawv yog tseem muaj, thiab tam sim no peb yuav nrhiav tau tawm ib qho twg.
Perlite yog dab tsi
Ua ntej txoj kev sib piv ntawm perlite thiab vermiculite, xav txog txhua yam ntawm cov ntaub ntawv nyias.
Perlite yog lub pob zeb ntawm volcanic keeb kwm thiab yog suav hais tias yog ib qho tseem ceeb heev pob zeb hauv av.
Thaum lub sij hawm hu rau lava nrog lub ntiaj teb, los yog ntau tshaj qhov tseeb, tam sim ntawd tom qab nws txias, lub pob zeb hu ua obsidian yog tsim, uas yog tom qab hydrated los ntawm av. Lub obsidian hydroxide resulting yog perlite.
Feem ntau cov ntaub ntawv no muaj nyob rau hauv kev tsim kho kev lag luam, uas yog siv rau cov hluav taws xob thiab cov hluav taws kub, thiab kev txo cov hluav taws. Feem ntau ua ntej daim ntawv thov kev nkag siab ntawm perlite dhau los kho cov cua sov hauv cov ncu tshwj xeeb, qhov chaw uas muaj kev kub ntxhov, nws swells (xws li paj kws).
Yog li ntawd, peb tau txais agroperlite, uas yog nyob rau hauv daim ntawv ntawm homogeneous tej khoom. Nyob hauv kev ua liaj ua teb, nws yog feem ntau siv nyob rau hauv av mulching, tab sis nyob rau hauv chav tsev teb nws muab ua ib qho zoo heev rau kev siv cov xuab zeb.
Pearlite zoo li cas rau paj? Nyob rau hauv qhov tseeb, nws yog ib qho yooj yim los mus piav qhia, vim hais tias nthuav txhab perlite, zoo li lub vermiculite piav tom qab, yog tiag tiag heev zoo li qub xuab zeb. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm perlite yuav luag zoo tib yam rau xuab zeb, vim nws yog raws li silicon oxide (IV).
Nws tsis pub leejtwg paub tias kev npaj ntawm ntau cov av sib xyaw av tsis tuaj yeem tsis muaj kev koom tes ntawm cov xuab zeb, vim tias nws muaj nyob rau hauv cov av muab cov pa tau zoo. Qhov no txhais tau hais tias thaum cog cov nroj tsuag nrog lub hauv paus tsis muaj zog, uas muaj xws li sab hauv paj, koj yuav muaj teeb meem tsawg dua.
Nws tseem ceeb heev! Kev siv cov kua dej thiab loosening Cheebtsam hauv cov av ua kom lub cev loj hlob ntawm cov nroj tsuag.Txawm li cas los, txawm tag nrho cov positives, lub tsev xuab zeb yuav tsis yuav heev rau cov nroj tsuag. Yog li no, cov kws txawj qhia kom siv cov khoom siv sib npaug nkaus xwb nyob hauv floriculture, tab sis nws tsis yooj yim nrhiav nws rau cov neeg nyob hauv nroog megalopolises.
Ib qhov ntuj tso rau hauv cov xuab zeb no yog perlite, vim nws yog tshuaj sib raug zoo thiab tsis muaj cov khoom siv, uas txhais tau hais tias nws lub ntsiab tseem ceeb yog kom plam cov av, tab sis tsis muaj ntxiv. Nrog rau kev siv ntawm cov khoom no, koj yuav ploj qhov teeb meem ntawm tsim ntawm ib crust nyob rau hauv lub Upper ib feem ntawm cov av, uas feem ntau tshwm raws li ib tug ntawm hauv av taug qabcia li sprinkle nrog perlite hauv av saum npoo). 
Ntawm qhov kev tsis zoo ntawm cov xuab zeb qhov hloov no yog qhov tsis zoo, vim tias cov khoom siv tsis muaj peev xwm ntawm kev ruaj ntseg thiab txum txav ntawm cov tshuaj hauv av, tab sis feem ntau qhov no tsis yog yuav tsum tau muaj.
Koj puas paub? Siv cov tshuaj agroperlite tshem tawm cov nroj tsuag. Qhov no feature piav qhia los ntawm kev kub (1100-1150 ° C) nrog nws cov khoom siv hauv qhov cub tawg. Uas yog, nrog xws li ib tug kub nyhuv loj, lub muaj pes tsawg leeg ntawm cov ntaub ntawv tiav tsuas yog tsis nyob twj ywm twg maj noob los yog larvae ntawm teeb meem kab.Lwm tus cwj pwm feature ntawm perlite yog nws cov tshuaj tsis haum alkaline, uas yuav tsum tau coj mus rau hauv tus account thaum cog nroj tsuag uas yuav tsum tau high acidity ntawm cov substrate (piv txwv li, cov chav nyob hauv inhabitants - gardenias thiab azaleas). Txwv tsis pub, lub ntim ntawm perlite siv yuav tsum sib haum mus rau tus nqi ntawm xuab zeb, uas yog, nroj tsuag nrog qaug zog keeb kwm, uas yuav tsum tau ib tug ntau xoob av, tseem yuav xav tau ntau perlite.
Nws tsis tau hais tias cov nroj tsuag nrog lub hauv paus loj muaj zog nyob zoo hauv ntom thiab clogged lub ntiaj teb, tab sis tus nqi ntawm cov khoom tau piav nyob rau hauv lub substrate yuav ua tau kev nyab xeeb txo.
Perlite yog zoo heev rau rooting cuttings, thiab germination yog ua tau txawm nyob rau hauv nws daim ntawv dawb huv.
Txawm li cas los xij, feem ntau, cov neeg cog khoom siv ib qho kev sib tov ntawm perlite nrog peat los yog sphagnum.
Tsis tas li ntawd, nws yog feem ntau siv rau germinating noob, vim hais tias thaum tov, nws muaj txhawb rau lawv ntau cov tsoog teeb meem tshaj cov av. Tau ntxiv ntxiv hmoov ntawm cov noob nrog rau cov khoom no.
Thaum twg cov dej cwj pwm cuttings perlite pab tiv thaiv lawv rotting, thiab thaum twg zus nyob rau hauv pearlite seedlings ntawm paj thiab zaub cov qoob loo, fungal kab mob (piv txwv li, blackleg) yog ntau tsawg dua.
Nws tseem ceeb heev! Thaum pouring qhuav khoom nws tsim ib tug ntau ntawm hmoov av, yog li nws yog ib qho tseem ceeb heev rau pre-moisten nws nrog dej.Vim muaj theem siab ntawm kev ua siab, cov khoom siv no feem ntau siv hauv hydroponics, qhov twg nws tseem siv ob qho tib si hauv daim ntawv dawb thiab nrog vermiculite.
Yuav ua li cas yog vermiculite
Vermiculite yog ib qho ntxhia uas muaj rau pawg hydromicas. Qhov no yog ib thaj chaw zoo nkauj (yuav luag sterile) uas tsis muaj hnyav lossis tshuaj lom. Nws tseem yuav tsum tau muab sau tseg tias nws tsis raug rau kev lwj lossis qhov rotting (uas yog feem ntau tshwm sim los ntawm kab mob) thiab tsis yog thaj chaw zoo rau cov nas tsuag thiab kab.
Nyob rau sab sab, vermiculite yog ib qho khoom siv ntawm cov khoom muag vermiculite tau raws li qhov tshwm sim, sawv cev los ntawm ore ntawm ib lub teeb gray xim thiab interspersed nrog loj zauv ntawm ntshiab mica. Nws cov loj, nruab nrab thiab me me feem ntau yog cov ntaub ntawv uas muaj ntau yam khoom uas tsim nyog rau ntau yam sib tov.
Cov feem me me ntawm cov hlau muaj xws li hmoov av lossis xuab zeb, tab sis feem ntau nws yog hu ua lub tsev khaws khoom ntawm cov tshuaj chemical, uas yog lub sij hawm nrog (muaj qhov tshwj xeeb ntawm cov cheeb tsam ntawm cov cheeb tsam) cov yas ci ntsa iab ntawm mica.
Lub ore yog kev ua tiav ntawm cov nroj tsuag uas cov neeg dawb huv tau sau los ua ke, thiab mam li txheeb thiab xa mus rau hauv kev lag luam hluav taws xob. Cov khoom ntxiv yog xa rau kev kho hydrothermal ntxiv nyob rau hauv qhov chaw sib xyaw roj hmab (diav rau 1400 degrees Fahrenheit).
Vim li ntawd, cov zauv feem ntawm ore txaus thiab ua kom zoo dua, tig mus rau ntau cov duab uas zoo ib yam li vermicelli. Nyob rau hauv lub neej yav tom ntej, tag nrho cov huab hwm coj resulting yog crushed thiab ua ntau zoo li flakes ntawm ntau ntau thiab tsawg: los ntawm hmoov av mus rau qhov loj ntawm npib.
Tau los ntawm roasting vermiculite, uas muaj lub npe agrovermiculite, - porous, lub teeb thiab tej khoom siv, nrog cov lus yaug cov hniav. Nws muaj ntau txoj kab tej khoom siv pab tau rau cov nroj tsuag, cov uas yog magnesium, calcium, txhuas, potassium, hlau thiab silicon. 
Nws yuav tsum raug sau tseg tias qhov txawv ntawm perlite thiab vermiculite yog precisely muaj cov kab kawm nyob rau hauv lub yav tas. Txawm li cas los xij, feem ntau ntawm cov khoom no yog nyob rau hauv cov ntaub ntawv tsis muaj siv, vim hais tias ntawm cov khoom lag luam tsis tuaj yeem pom tias cov khoom tseem ceeb ntawm cov khoom tsim nyog rau cov nroj tsuag.
Qhov siab hloov ion-txauv peev ntawm vermiculite tso cai rau nws khaws zoo zoo ions ntawm magnesium, poov tshuaj, thiab lwm cov fertilizer hais nkag mus rau hauv cov av, thiab maj muab lawv mus rau nroj tsuag.
Cov ntaub ntawv uas tau piav qhia yog txawv thiab txaus cov dej noo ntau, txij li thaum nws ntub nws nyob hauv nws tus kheej ib phaus tsib zaug ntau dua li nws tus kheej.
Nws tseem ceeb heev! Txawm hais tias mus rau hauv tus account no feature, kev siv vermiculite tsis ua cov av hnyav thiab tso cai rau nws kom yooj yim yuav aerated thaum muab ib tug zoo mov ntawm noo noo.Ib qho kev ua ntawm perlite thiab vermiculite rau paj yog qhov peev xwm siv nyob rau hauv ntau txoj kev: nyob rau hauv daim ntawv ntshiab (piv txwv li, rau rooting cuttings los yog noob germination) thiab raws li ib feem ntawm lwm yam mixtures.
Vermiculite zoo tiv thaiv hauv paus system ntawm nroj tsuag los ntawm kub hloov, uas yog tseem ceeb heev thaum loj hlob seedlings, thiab txij li thaum nws yog sterile, nws tsis muaj microorganisms thiab fungi, nws kuj yog ntxwv ntawm lub peev xwm los tiv thaiv qhov tsos ntawm rot thiab fungal kab mob. Lub cuttings muab tso rau hauv lub agro vermiculite paus zoo thiab cia offspring.Qhov no feature tau ua ib qho khoom nruab nrab ntawm lub ntiaj teb cov khoom sib xyaw hauv ntau yam khoom (txog li 50% ntawm lub teb chaws substrate), thiab cov friability, porosity thiab av noo noo yeej rov qab mus li qub.
Vim lub nruab nrab acidity (pH), vermiculite significantly txo lub acidity ntawm av substrate thiab slows down tus txheej txheem ntawm nws salinization.
Cov khoom zoo ntawm cov khoom muag pom lawv tus kheej thaum lub caij ntuj no cia ntawm cov nroj tsuag hlav, vim tias cov thermal conductivity ntawm cov khoom tso cai rau nws kom muaj cua kub tshuav nyob ib ncig ntawm lub qhov muag teev, thaum tuav txoj kev sib hloov roj. Lub qhov muag teev nyob rau hauv cov ntaub ntawv yuav tsis rot, thiab lawv yuav tsis tsum cuam tshuam los ntawm ib tug fungal tau tus kab mob.
Qhov txawv ntawm perlite thiab vermiculite yog dab tsi
Thaum kuaj cov av thiab cov txiv hmab txiv ntoo thiab cov khoom sib xyaw es thiaj li pom tau tias lawv cov khoom thiab cov khoom sib xyaw, muaj qee cov ntsiab lus tseem ceeb (piv txwv, thaum siv ob yam khoom sib xyaw hauv cov av sib xyaw), tab sis qhov no tsis txhais hais tias lawv yog cov qub. .
Kev kawm txog cov yam ntxwv ntawm perlite thiab vermiculite thiab txiav txim siab seb qhov twg yog qhov zoo tshaj plaws rau koj cov xim, ua ntej tshaj, koj yuav tsum them nyiaj rau lub ntsiab sib txawv: ib tsos tsaus tsawv xim ntawm vermiculite thiab nws muaj peev xwm mus zais thiab maj mam tso tawm cov zaub mov thiab dej. Tias yog vim li cas, muab qhov preference rau cov khoom no, watering nroj tsuag yuav tsum tau txo.
Nyob rau tib lub sij hawm, perlite yog sai npaum li cas nrog rau cov kua, uas txhais tau hais tias qhov zaus ntawm nws cov kev taw qhia rau hauv av, nyob rau hauv tsis tooj, nce.
Ob leeg cov ntaub ntawv yog volcanic keeb kwm, tsuas perlite - nws tsuas yog melted thiab foamed xuab zeb (iav yuav hais tau)thiab vermiculite tseem muaj cov tshuaj pob zeb me me.
Yog hais tias koj xav tau mus rau paus lub cuttings, nws yog ib qho zoo tshaj plaws muab preference rau vermiculite. Nws muab tsawg zuj zus thaum lub sib tsoo (tsis tshuav tsawg dua), tsis muaj voids thaum rov qab thiab muaj qes zog tsis muaj zog (tsis muaj kev cuam tshuam ntawm cov cag).
Tsis tas li ntawd nyob rau hauv kev sib piv nrog perlite, vermiculite yog tsawg hygroscopic thiab tsawg ionic. Txawm li cas los xij, qhov zoo ntawm perlite kuj tsis tuaj yeem tsis quav ntsej txog, vim nws muab cov qoob loo ntawm cov dej noo, muab cov kua yooj yim dua thiab dries sai ntawm cov irrigations.
Ob lub perlite thiab vermiculite muaj cov qauv zoo heev, uas ua rau lawv yog ib tug zoo substrate rau sab hauv paj, tab sis tsuas yog los ntawm kev nkag siab txog qhov txawv ntawm lawv yog, koj tuaj yeem ua qhov xaiv zoo rau txhua tus neeg.
