Hauv cov ntawv dhau los, peb tau hais txog qhov tseem ceeb ntawm "carbon to nitrogen ratio" hauv kev tsim cov chiv ntau zaus, tab sis tseem muaj ntau tus neeg nyeem uas tseem muaj kev tsis ntseeg txog lub tswv yim ntawm "carbon to nitrogen ratio" thiab yuav ua li cas khiav lag luam.Tam sim no peb yuav los.Tham txog qhov teeb meem no nrog koj.
Ua ntej, "carbon to nitrogen ratio" yog qhov piv ntawm carbon rau nitrogen.Muaj ntau yam khoom siv hauv cov khoom siv compost, thiab carbon thiab nitrogen yog ob qho tseem ceeb tshaj plaws:
Cov pa roj carbon monoxide yog ib yam khoom uas tuaj yeem muab lub zog rau cov kab mob, feem ntau, carbohydrates, xws li qab zib xim av, molasses, starch (pob kws hmoov), thiab lwm yam, yog tag nrho cov "carbon sources", thiab straw, nplej straw, thiab lwm yam straws tuaj yeem ua tau. nkag siab tias "cov khoom siv carbon".
Nitrogen tuaj yeem nce nitrogen rau kev loj hlob ntawm cov kab mob.Dab tsi yog nplua nuj nyob rau hauv nitrogen?Urea, amino acids, qaib quav (khoom noj khoom haus yog high-protein pub), thiab lwm yam. Feem ntau hais lus, cov ntaub ntawv uas peb ferment yog feem ntau nitrogen qhov chaw, thiab ces peb tsim nyog ntxiv "carbon qhov chaw" raws li xav tau los kho cov carbon rau nitrogen piv.
Qhov nyuaj ntawm composting nyob rau hauv yuav ua li cas tswj cov carbon-nitrogen piv nyob rau hauv ib tug tsim nyog ntau yam.Yog li ntawd, thaum ntxiv cov ntaub ntawv compost, txawm siv qhov hnyav los yog lwm yam kev ntsuas, ntau yam ntaub ntawv compost yuav tsum tau hloov mus rau qhov sib npaug ntawm qhov ntsuas.
Nyob rau hauv cov txheej txheem composting, cov dej noo ntawm kwv yees li 60% yog qhov zoo tshaj plaws rau microbial decomposition, txawm hais tias cov pa roj carbon-nitrogen piv ntawm cov khoom noj khib nyiab yog ze rau 20: 1, tab sis lawv cov ntsiab lus dej yuav nyob nruab nrab ntawm 85-95%.yog li ntawd.Nws yog feem ntau yuav tsum tau ntxiv cov ntaub ntawv xim av rau hauv chav ua noj khib nyiab, cov khoom siv xim av tuaj yeem nqus tau cov dej noo ntau dhau.Cov nplooj lwg nplooj lwg yuav tsum tig los ntawm cov khoom siv.compost turnerrau ib lub sij hawm los txhawb airflow, txwv tsis pub, lub compost yuav stink.Yog hais tias cov ntaub ntawv compost yog ntub heev, txav mus rau carbon rau nitrogen piv ntawm 40: 1.Yog hais tias cov ntaub ntawv compost twb ze rau 60% noo noo, nws yuav sai sai no muaj peev xwm cia siab rau lub zoo meej piv ntawm 30: 1.
Tam sim no, peb yuav qhia koj txog qhov ua tau zoo tshaj plaws ntawm carbon-nitrogen piv ntawm cov ntaub ntawv composting.Koj tuaj yeem kho tus naj npawb ntawm cov ntaub ntawv nto moo raws li cov ntaub ntawv composting koj tuaj yeem siv thiab muab cov kev ntsuas saum toj no los ua kom cov pa roj carbon-nitrogen piv rau qhov zoo meej.
Cov piv txwv no yog nyob ntawm qhov nruab nrab thiab qhov tseeb C: N, tej zaum yuav muaj qee qhov kev hloov pauv hauv cov txheej txheem tiag tiag, txawm li cas los xij, cov no tseem yog ib txoj hauv kev zoo heev los tswj cov pa roj carbon thiab nitrogen hauv koj cov compost thaum koj ua composting.

Ntshav hmoov yog hmoov tsim los ntawm kev ziab ntawm cov ntshav tsiaj.Ntshav hmoov yog siv los ua kom cov ntsiab lus ntawm nitrogen cables hauv av, ua rau cov nroj tsuag loj hlob denser thiab zaub ntsuab ntau "ntsuab".Contrary to pob txha hmoov, ntshav hmoov tuaj yeem txo cov pH ntawm cov av thiab ua rau cov av acidic.Cov av zoo heev rau cov nroj tsuag.
Lub luag hauj lwm ntawm cov ntshav hmoov thiab pob txha hmoov Lawv muaj txiaj ntsig zoo rau kev txhim kho av, thiab kev fertilization tsis ncaj ncees lawm yuav tsis hlawv koj cov nroj tsuag.Yog hais tias cov av yog acidic, siv cov pob txha noj mov kom nce cov ntsiab lus ntawm phosphorus thiab calcium, ua rau cov av alkaline, Nws yog haum rau flowering thiab txiv hmab txiv ntoo nroj tsuag.Yog hais tias cov av yog alkaline, siv cov ntshav hmoov los ua kom cov nitrogen cov ntsiab lus thiab ua rau cov av acidic.Nws yog haum rau cov nplooj ntoo.Nyob rau hauv luv luv, ntxiv ob saum toj no rau lub compost yog zoo rau composting.
Yuav xam li cas
Raws li cov pa roj carbon-nitrogen piv ntawm ntau yam ntaub ntawv uas tau muab rau hauv cov npe saum toj no, suav nrog cov khoom siv hauv kev sib xyaw ua ke, suav tag nrho cov khoom sib xyaw ua ke, suav cov ntsiab lus carbon tag nrho, thiab muab faib los ntawm tag nrho cov khoom siv los ua Tus lej no yuav tsum nyob nruab nrab ntawm 20 thiab 40.
Ib qho piv txwv los piav qhia yuav ua li cas cov carbon rau nitrogen piv yog xam:
Piv txwv tias muaj 8 tons ntawm nyuj dung thiab nplej straw ua cov khoom pab, peb yuav tsum tau ntxiv cov nplej straw ntau npaum li cas los ua kom cov pa roj carbon-nitrogen piv ntawm tag nrho cov khoom mus txog 30: 1?
Peb ntsia lub rooj thiab pom tias carbon-nitrogen piv ntawm nyuj dung yog 15: 1, carbon-nitrogen piv ntawm nplej straw yog 60: 1, thiab carbon-nitrogen piv ntawm ob yog 4: 1, yog li peb. tsuas yog yuav tsum tau muab cov nplej straw rau hauv 1/4 ntawm tus nyuj dung npaum li cas.Yog, uas yog, 2 tons ntawm nplej straw.
