Peat - dab tsi yog qhov no? Extraction, lub zog thiab kev siv ntawm peat

Raws li ceev faj kev kwv yees ntawm zaum, raws li ntawm hnub no, lub peat reserves rau peb ntiaj chaw nyob rau hauv qhov kev txiav txim ntawm tsib puas billion tons. Ib tug tseem ceeb kev faib ua feem yog feeb meej nyob rau hauv sab qaum teb Hemisphere. Yog vim li cas rau qhov no yog heev yooj yooj yim thiab lwm yam kev mus climatic tej yam kev mob, namely - ntsuas ntawm nruab nrab txhua xyoo dej nag thiab humidity. Nyob rau hauv no tsab xov xwm peb yuav kub siab rau dab tsi yog peat, raws li zoo raws li nws cov ntaub ntawv, yam ntxwv thiab daim ntaub ntawv.

dav tswvyim

Ua ntej ntawm tag nrho cov, nws yuav tsum tau muab sau tseg hais tias nws yog ib tug ntawm cov hom ntawm cov khoom minerals, uas yog feem ntau siv rau roj ntau lawm. Nws yog tsim nyob rau hauv ib tug swampy cheeb tsam, thiab yog cov kev tshwm sim ntawm ib tug loj congestion ntawm ntau yam organic hais tias yog tsis decomposed. Raws li ib tug txoj cai, lub thickness ntawm lub tso ntawm nws cov khaubncaws sab nraud povtseg yog tsis tsawg tshaj li peb caug centimeters. Nws yog tsis yooj yim sua tsis kom nco ntsoov qhov tseeb hais tias peat - yog minerals, uas ntau tshaj ib nrab muaj carbon. Sib nrug los ntawm nws, tus qauv muaj xws li calcium, poov tshuaj, phosphorus, hlau, nitrogen thiab humic acid, thiab zaub fibers. Niaj hnub nimno science qhia ob yam loj ntawm nws zoo - thiab lowland peat ntxhuab.

Cov cheeb tsam ntawm siv

Txha pom haum thoob plaws siv. Nyob rau hauv kev, nyob rau hauv ua liaj ua teb siv ntawm peat txuas rau tsim fertile chiv, nroog txoj kev greening txheej txheem, Vov cov av, thiab hais txog. Nyob rau hauv lub tsiaj nyeg kev lag luam , nws feem ntau ua raws li ntaub pua chaw pw rau tej tsiaj txhu. Nyob rau hauv tas li ntawd, nws yog siv raws li ib tug roj thiab rau zus tau tej cov pharmaceuticals.

Ntsiab nta

Raws li twb tau sau tseg, muaj ntau pab tau thaj chaw ntawm peat cia nws siv nyob rau hauv ib tug ntau yam ntawm tib neeg kev ua si. Nyob rau hauv kev, lub pob txha muab ib tug tseem ceeb kev txhim kho nyob rau hauv cov huab cua-dej mob ntawm av, li no kom lawv tsim tau thiab fertility. Nyob rau tib lub sij hawm peb yuav tsum tsis txhob hnov qab txog lub nuance hais tias ua ntej siv nyob rau hauv floriculture los yog horticulture nws yuav tsum yaig, yog li xa teeb meem rau ntau yam nroj tsuag acid. Nws yuav siv sij hawm ib tug nruab nrab ntawm txog peb lub xyoos. Ntxiv mus, cov ntaub ntawv uas muab ib tug high school cov av noo noo muaj peev xwm sib txawv ntawm cov mixtures ua rau lub hauv paus ntawd.

Txha plays ib tug tseem ceeb heev luag hauj lwm nyob rau hauv cov xwm. Lub fact tias muaj yog tsim khoom ntawm photosynthesis, atmospheric carbon. Ntawm lwm yam, lub substance ua raws li ib yam ntawm tej yam ntuj tso dej lim, vim hais tias cov khoom ntawm peat pub rau deduce los ntawm nws cov tswv cuab ib tug ntau yam ntawm impurities, uas muaj xws li txawm hnyav hlau. Qhov no yog nws ecological muaj nuj nqi.

lowland peat

Tus thawj ntawm lub aforementioned cov pob txha muaj ib tug uas tsis muaj theem ntawm acidity. Nws muaj xws li ib tug ntau yam ntawm cov as-ham, ua rau nws ib qho zoo heev chiv. Qhuav ntawm no hom yuav feem ntau manufactured nyob rau hauv peat bogs, hav dej tsim nyob rau hauv los yog nyob ze ntawm lub ko taw ntawm tus nqes hav. Nws pab zog txuam nrog rau qhov kev tsuas xyaus ntawm cov dej vim lub surrounding lub cev ntawm cov dej thiab nag lossis daus. Cov pob txha yog tsis zoo decomposed, srednerazlozhivshimsya los sis mob loj decayed. Hais tias kev xaiv kawg nkaus yog xav tau qhov zoo tshaj plaws tshuaj mus rau fertilize lub av.

nees saib

Peat - ib tug zoo uas yog tsim los ntawm decomposition ntawm paj rwb nyom, ntoo thuv los yog sphagnum los ntawm qhov kev txiav txim ntawm dej nag. Nyob rau hauv feem ntau, nws ua raws li ib tug roj los yog constituent qhov chaw ntawm ntau yam ntaub ntawv siv rau thermal rwb thaiv tsev ntawm cov vaj tse. Nyob rau hauv tas li ntawd, siv ntau ua mulch. Ib tug yam ntxwv feature ntawm lub hom yog tus tsis muaj nyob rau hauv nws muaj pes tsawg leeg ntawm kab, pathogens thiab maj noob. Nyob rau hauv kev twb kev txuas nrog rau qhov no pob txha yog feem ntau pom nyob rau hauv greenhouses thiab greenhouses. Txawm nws yog, nws yuav tsum tau muab sau tseg tias nws yog neeg pluag nyob rau hauv cov as-ham thiab txaus qaub. Qhov no pub rau nws siv raws li ib tug fertilizer rau xwb ib ob peb hom ntawm cov nroj tsuag.

tsim

Sib nrug los ntawm lub fact tias qhov no peat, nws yog tsis yooj yim sua tsis kom nco ntsoov qhov kev txiav txim ntawm tsim ntawm lub pob txha. Nws tshwm sim raws li ib tug tshwm sim ntawm cov cem tseg nyob rau hauv marshland nroj tsuag, uas ces rot nyob rau hauv tus ntawm lub Excellency ntawm tus nqi ntawm cov dej nyob rau hauv lub tej yam kev mob ntawm tsis muaj oxygen. Cov tshuaj yeeb dej caw muaj ib tug xim av los yog xim dub thiab yog fibrous nyob rau hauv cov qauv. Nyob rau hauv tej yam ntuj tso tej yam kev mob, nws yog tam sim no nyob rau hauv ib tug loj kev faib ua feem ntawm cov dej.

Ntsiab tsis

Peat deposit yog lub concentration ntawm cov xwm sib txawv thiab hom ntawm cov khoom khaubncaws sab nraud povtseg, uas yog nyob rau ntawm ib tug cheeb tsam. Nyob rau hauv cov kev tshwm sim hais tias nws tob nyob rau hauv lub undrained mob nce mus txog xya caum centimeters, nws yog suav tias yog ib tug geological cia. Nws yuav tsum tau muab sau tseg tias peat - ib tug raw khoom, uas thaum lub sij hawm nws tsim acquires cim cov ntsiab lus ntawm phosphorus, nitrogen, poov tshuaj thiab lwm yam minerals. Nyob rau hauv tas li ntawd, qhov sib txawv deposits txawv nyob rau hauv indicators xws li humification, tshauv thiab dej feem pua.

Lub tswvyim ntawm humification txhais tau tias qhov feem pua ntawm cov pa roj carbon muaj nyob rau hauv nyob tus yeees ntawm peat thiab fertile thiab as-ham rau nws yuag tag nrho. Yog hais tias qhov no daim duab yog tsawg tshaj li 20 feem pua, ib tug tsawg kawg nkaus deposit nyiaj ntawm degradation thaum muab cia rau hauv lub chav los ntawm 20 mus rau 35 feem pua - nruab nrab, tab sis nyob rau hauv lwm tus neeg mob - siab.

Nyob rau hauv lub txheeb ze humidity ntawm peat yog ib tug muaj nuj nqis ntawm cov dej nyob rau hauv tag nrho cov loj feem pua, thiab nyob rau hauv lub meej - tib yam nqi qhia nyob rau hauv grams.

Cov tshauv cov ntsiab lus yog tseem ceeb heev parameter uas characterizes lub peat. Qhov no tus nqi qhia qhov feem pua piv ntawm cov ntsiab lus ntawm cov mineral Cheebtsam thiab tus nqi ntawm qhuav teeb meem.

Txaus ntshai thiab tsis muaj txuam nrog peat

Cov kev loj hlob ntawm peat bogs pw tej kev txaus ntshai. Lawv feem ntau muaj feem xyuam rau lub fact tias nyob rau hauv tus txheej txheem ntawm ziab yuav ceev xaiv yav tas los absorbed carbon dioxide. Nyob rau hauv tas li ntawd, muaj ntau yam ntawm peb tau hnov txog cov hluav taws kub. Kev tshawb fawb qhia tau hais tias los ntawm lawv tus kheej lawv yeej yuav tsis tshwm sim, vim hais tias yog lub txiaj ntsim ntawm tib neeg kev ua si, aimed ntawm txhuav ntawm peatlands thiab mineralization.
