Cov nyom zoo nkauj nrog lub hau kaw thiab cov xim ntsuab ntsuab yog qhov ntau tus tswv vaj xav tau. Kev saib xyuas ua lub luag haujlwm tseem ceeb hauv qhov no. Cov lus nug ntawm qhov ceev ntawm kev loj hlob yog ncaj ncees, vim hais tias kev loj hlob ntawm cov nyom txiav txim siab lub voj voog mowing. Txawm li cas los xij, kev loj hlob sai npaum li cas nyob ntawm ntau yam. Kev loj hlob tuaj yeem txhawb nqa los ntawm kev ntsuas tshwj xeeb.
Influencing factors
Txhua cov nyom siv sijhawm sib txawv kom loj hlob. Nws tuaj yeem siv li ntawm xya mus rau 20 hnub rau thawj stalks kom tawg. Txoj kev taug kev los ntawm cov noob mus rau cov nyom nyom yog txheej txheem nyuaj, lub sijhawm uas nyob ntawm ntau yam:
- Type of nyom: Fescue, meadow panicle, ryegrass, bentgrass
- Lawn type: Ornamental lawn, sports lawn, ntxoov lawn
- Environmental factors: Kub, teeb, nag lossis daus
Cov nyom thiab hom nyom
Cov nyom nyom muaj cov kab zoo-leaved uas qhia tias kev loj hlob qeeb. Kev saib xyuas yuav tsum yog qhov sib piv qis vim tias nplooj nplooj tsis nce sai thiab cov nyom yuav tsum tau mowed tsawg zaus. Kev ua si thiab kev ua si turf yog tus cwj pwm los ntawm lawv cov kav ntev. Lawv muaj xws li tshwj xeeb tshaj yog loj hlob sai thiab robust hom nyom uas kaw txawm liab qab me ntsis nyob rau hauv ib lub sij hawm luv luv. Vim txoj kev loj hlob sai, cov nyom no yuav tsum tau mowed ntau zaus. Ntxoov ntxoo cov nyom muaj ntau hom nyom uas tuaj yeem tiv nrog lub teeb qis. Nyob rau hauv shady tej yam kev mob, txoj kev loj hlob yog me ntsis qeeb, yog li no hom nyom yuav tsum tau saib xyuas tsawg. Ntau hom nyom kuj muaj nyob rau hauv lwm qhov sib xyaw. Ntxoov ntxoo cov nyom muaj qhov sib npaug ntawm cov nyom ripseed lossis meadow panicle.
- Ornamental lawn:Nkauj nyom, fescues
- Sports turf: Rye grasses, meadow panicle
- ntxoov ntxoo lawn: Fescue, ryegrass, bluegrass
Lub sij hawm germination
Cov hom nyom siv sij hawm sib txawv kom germinate. Lub sij hawm germination yuav tsum yog li ntawd yuav tsum tau coj mus rau hauv tus account rau cov nyom tshiab nteg nyob rau hauv thiaj li yuav tau txais cov ntaub ntawv hais txog kev loj hlob tus nqi. Zoo li kev loj hlob ntawm cov nyom, nws nyob ntawm qhov chaw ib puag ncig. Qhov nruab nrab, cov nyom no muaj lub sijhawm germination hauv qab no:
- Redgegrasses: txog xya mus rau 15 hnub
- Fescue: ntawm kaum mus rau 20 hnub
- Bentgrasses: kaum ob mus rau 20 hnub
- Panel grasses: approx. 14 mus rau 24 hnub
Note:
Txawm hais tias thawj cov lus qhia nyom tshwm tom qab ib lub lim tiam, koj yuav tsum cia qee lub sijhawm dhau mus ua ntej thawj mowing. Thaum tag nrho cov nyom tau nce mus txog qhov siab ntawm yim centimeters, koj tuaj yeem txiav thawj zaug.
Environmental factors
Kev loj hlob yog txhawb los ntawm qhov kub thiab txias. Qhov tseem ceeb tshaj plaws yog av kub ntawm qhov tob ntawm ib ncig ntawm tsib centimeters. Rau kev noj qab haus huv hauv paus thiab tua kev loj hlob, qhov kub yuav tsum nyob nruab nrab ntawm 15 txog 18 degrees Celsius. Thaum cov noob tau tsim cotyledons, hnub ci ua lub luag haujlwm tseem ceeb hauv kev loj hlob tom ntej. Nyom siv lub hnub lub zog los tsim cov as-ham. Sun-drenched lawns yog li ntawd loj hlob sai tshaj cov nyom nyob rau hauv ntxoov ntxoo. Txawm li cas los xij, qhov no tsuas yog ua haujlwm yog tias qhov sib npaug dej raug raug. Hnub ci ntau dhau ua rau cov nyom poob dej ntau dhau los ntawm evaporation. Nyob rau lub caij ntuj sov, qhov xav tau dej ib square meter yog nyob ib ncig ntawm tsib litres. Yog lub ntuj tsaus, qhov xav tau ntawm cov kua yuav txo.
Note:
Lub caij nplooj zeeg, qhov kev loj hlob tsis tu ncua txo qis vim qhov kub thiab txias txo. Cov stalks nres loj hlob ntawm ib ncig ntawm tsib degrees Celsius huab cua kub, thaum lub hauv paus kev loj hlob nres ntawm -0.5 degrees Celsius.
Accelerating kev loj hlob
Loos cov av kom huv si ua ntej tseb. Qhov no ua rau cov noob poob rau hauv kev tiv thaiv kab nrib pleb hauv lub ntiaj teb uas cov xwm txheej tsis sib xws. Npog cov noob tsuas yog thinly nrog substrate kom cov sprouts tuaj yeem loj hlob sai dua los ntawm cov av. Cov tsiaj tsis xav tau yuav tsum tau muab tshem tawm sai sai. Txawm hais tias feem ntau hom nyom yog qhov sib tw thiab tuaj yeem tuav lawv tus kheej tawm tsam lwm cov nroj tsuag, thiaj li hu ua cov nroj tsuag rob cov nyom ntawm cov as-ham. Muab cov noob nrog ib qho pib chiv. Lawv muab cov nyom me me nrog cov khoom noj tseem ceeb rau kev loj hlob sai thiab noj qab haus huv, yog li phosphorus yuav tsum ua kom muaj feem ntau ntawm cov chiv chiv.
- Nitrogen: Nplooj hlob
- Potassium: nce kev tiv thaiv
- phosphorus: Rooting
Tip:
Cov nyom me me yuav tsum tau siv cov as-ham sai li sai tau. Yog li ntawd, thov pib chiv ib mus rau ob lub lis piam ua ntej sowing.
