Cov qoob loo yog ib yam khoom uas muaj txhij txhua, tau vim yog lub sijhawm ntawm ib nrab ntawm cov nroj tsuag seem nyob rau hauv tej yam kev mob ntawm cov av qeeg (swamp). Nyob rau hauv ib peat substratum, tag nrho volume ntawm peat yuav siv sij hawm los ntawm 50 mus rau 100% ntawm tag nrho volume.
Qhov tseem ceeb tshaj plaws peat yog lub peat saum toj kawg nkaus , nws yog ib qho tsis tshua muaj txiaj ntsim thiab noj cov khoom tsis zoo. Nws yog lub substrate raws li peat siv raws li ib tug neeg hloov zov rau av rau ntau yam nroj tsuag tsiaj.
Ib co nroj tsuag yuav tsum xav tau ib peat substrate. Piv txwv, orchids: thaum tsim ib qho substrate rau lawv, koj yuav tsum nco ntsoov tias nws yuav tsum txaus haus noo thiab haus tau. Lub substrate nrog peat, tawv thiab sphagnum rau phalaenopsis (orchids) ua tau raws li cov kev cai no rau lub siab dawb paug.
Nta ntawm peat nutrient substrate
Qhov feem ntau yog tofood yog sphagnum Moss. Thiab sphagnum peat bogs yog feem ntau ntau qhov chaw ntawm peat thiab substrate. Nyob rau hauv no sphagnum nws muaj nws tus yam ntxwv, uas yog cov yam ntxwv ntawm peat tsim los ntawm lawv.
Lub ntsiab feature ntawm sphagnum peat bogs yog ib tug loj capillarity thiab, raws li, noo noo muaj peev xwm. Qhov feem ntau ntawm cov dej-intensive sphagnum muaj peev xwm sawv ntawm absorbing ya raws 50 zaus ntau tshaj li lawv cov huab cua qhuav. Nws yog ib qhov muaj kuab uas peat absorbs noo noo heev zoo.
Tsis tas li ntawd, lub peat substrate maximally raws li kev xav tau ntawm cov nroj tsuag hauv micro- thiab macroelements, vim nws yog siv rau cov nroj tsuag loj hlob nyob rau hauv pots thiab ntim, raws li tau zoo rau kev cog qoob loo ntawm cov qoob loo. Nyob rau hauv nws, qhov kev ntawm germination ntawm noob yog ceev, yog li ntawd xws li ib tug substrate yog feem ntau xaiv rau yuam seedlings.
Disadvantages ntawm peat substrate
Peat raws li ib tug substrate yog tsis universal rau tag nrho cov nroj tsuag tsiaj. Cov kua qaub qhov chaw nyob hauv peat substrates tsis haum txhua tus neeg sawv cev ntawm cov tsiaj muaj.
Yuav kom txo acidity nyob rau hauv substrate los yog peat ntsiav tshuaj, chalk los yog txiv qaub feem ntau ntxiv. Tab sis qhov no, nyeg, ua rau ntau cov ntsiab lus ntawm calcium nyob rau hauv lub substrate, uas adversely cuam tshuam rau kev loj hlob ntawm cov nroj tsuag, vim nws ua rau ib tug tsis muaj phosphorus thiab ib co kab kawm.
Tsis tas li ntawd, nyob rau hauv tus txheej txheem ntawm neutralizing acidity, kev ua si ntawm humic tshuaj ntawm peat tej zaum yuav txo, thiab qhov no txo cov efficiency ntawm peat thiab ua rau nws tsis yooj yim sua kom siv cov khoom tseem ceeb ntawm peat mus rau lub siab.
Thiab ib qho ntau tshaj plaws: vim ntawm xoob thiab ntxeem qauv ntawm peat substrate, nws sai sai poob moisture, vim hais tias cov nroj tsuag yuav tsum tau ntau heev watering. Vim yog lub zog evaporation ntawm noo noo thiab ib tug poob nyob rau hauv kub, hauv paus system tej zaum yuav raug kev txom nyem, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem mob.
