Thaum xub thawj siab ib muag tej zaum koj yuav xav tias kev cog qoob loo yog qhov yooj yim. Tab sis nyob rau hauv ntau zaus, av, noo noo thiab sov so nyob deb ntawm txaus. Hloov chaw, cov noob xav tau kev txhawb nqa sab nraud kom germinate thawj qhov chaw. Koj tuaj yeem paub yuav ua li cas thiaj li tsim tau qhov stratification no hauv cov lus qhia hauv qab no:
Vim li cas stratify txhua?
Nyob rau hauv qhov xwm txheej nws yog feem ntau npaj kom cov nroj tsuag kis lawv cov noob nyob rau hauv ntau txoj kev tom qab txiv hmab txiv ntoo ripening. Txawm li cas los xij, lawv yuav tsum tsis txhob germinate thiab loj hlob mus rau hauv cov nroj tsuag kom txog thaum lub caij nplooj ntoos hlav tom ntej. Qhov no muab sijhawm rau cov yub kom ntau li ntau tau los npaj rau lub caij ntuj no tom ntej nrog tag nrho nws cov kev cov nyom los ntawm kev loj hlob thiab ntxiv dag zog.
Yog li ntawd qhov ncua sij hawm ntawm germination tshwm sim, xwm tau tsim nyob rau hauv txawv mechanisms inhibit germination:
- Inhibition los ntawm organic acids nyob rau hauv lub pulp - nyob rau hauv lub cev nqaij daim tawv pob zeb txiv hmab txiv ntoo (peach, cherry, noog cherry, qus sawv, thiab lwm yam)
- Inhibition los ntawm cov tshuaj hormone- thiab enzyme-zoo li tshuaj nyob rau hauv lub yub los yog noob lub tsho tiv no (xws li witch hazel, viburnum, yew, thiab lwm yam)
- Mechanical germination inhibition, feem ntau ua ke nrog enzymatic inhibitors (tshwj xeeb yog cov ntoo ntoo nrog cov noob tawv tawv (beech, ntoo qhib, txiv ntseej, thiab lwm yam)
Yuav ua li cas stratify - lus qhia
Vim tias muaj cov txheej txheem sib txawv ntawm cov kab mob inhibition, ntau txoj hauv kev yuav tsum tau kov yeej. Txij li cov inhibitors sib txawv feem ntau tshwm sim ua ke hauv qhov xwm txheej, nws yuav tsim nyog los ua ke ntau yam kev ntsuas rau stratification:
Stratification ntawm cov organic acids li germination inhibitors
Koj tuaj yeem sib cav txog seb qhov no puas yog kev sib tw tiag tiag, raws li tau piav qhia ntau zaus hauv cov ntawv nyeem. Qhov tseeb yog qhov tseem ceeb uas inhibit germination raug tshem tawm tshwj xeeb ntawm no txhawm rau kom ntseeg tau tias cov noob tuaj yeem germinate.
Application
rau cev nqaij daim tawv
Inhibition txheej txheem
- Kev loj hlob ntawm cov organic acids nyob rau hauv lub pulp los ntawm txiv hmab txiv ntoo ripening
- Ntseeg ntawm cov kua qaub rau txiv hmab txiv ntoo
- Qhov tshwm sim ntawm cov nyhuv inhibitory
txheej txheem tshem tawm qhov inhibition
- Tau txiv hmab txiv ntoo tawm hauv qhov qhib cua thiab tshav ntuj
- Tau kom lub pulp pib rotting
- Tshem tawm cov nqaij seem ntawm cov noob, piv txwv li los ntawm kev txhuam lossis txhuam nrog koj txhais tes lossis nruab nrab ntawm ob lub pob zeb lossis cov phaj ntoo
- ntxuav cov noob hauv dej kom tsis txhob rot ntxiv
- Kub cov kernels kom tiv thaiv tau germination tam sim ntawd
- Kho kom qhuav thiab airtight kom txog thaum sowing
ALTERNATIVE
Ib txoj kev thib ob, ntxiv rau kev tshem tawm cov pulp thiab txiv hmab txiv ntoo acids, yog kom sau cov txiv hmab txiv ntoo ua ntej nws puv puv. Ua li no, kev loj hlob raug nres ua ntej cov kua qaub tsim tawm thiab cov noob tuaj yeem tau txais los nthuav tawm cov nroj tsuag raws li tau piav qhia saum toj no.
Tip:
Daim ntawv no ntawm kev cog qoob loo yog qhov yooj yim tshaj plaws thiab yooj yim sib txawv los siv. Txawm li cas los xij, koj yuav tsum ua tib zoo ua tib zoo. Cov dej noo tshwj xeeb tuaj yeem dhau los ua teeb meem vim qhov tsis xav tau rau kev cog qoob loo lossis cov xwm txheej zoo rau kev loj hlob ntawm cov kab mob putrefactive.
Stratification rau cov tshuaj hormone lossis enzyme-zoo li tshuaj
Cov feem ntau hom stratification yog siv thaum cov tshuaj hormones los yog enzymes tshwm sim raws li kev loj hlob inhibitors. Qhov no hu ua txias stratification.
Application for
Cold germination, uas nws cov noob xav tau lub caij txias kom germinate
Inhibition txheej txheem
- Txoj kev loj hlob ntawm inhibitory messenger tshuaj nyob rau hauv yub los yog noob lub tsho tiv no
- Decomposition of messenger substances vim lub caij txias
txheej txheem rau stratification
- Sau lub thawv nrog xuab zeb, lossis hloov xuab zeb thiab peat
- Muab cov noob huv si tso rau hauv lub substrate thiab quav hauv
- Moisten lub substrate, xws li ua tib zoo watering nws
- Khaws lub thawv rau hauv qhov chaw txias, xws li hauv qab daus, chaw nres tsheb lossis tub yees
- Qhov kub zoo tshaj plaws: 2 txog 8 degrees Celsius
- Tig lub substrate nrog rau cov noob tsis tu ncua, piv txwv li txhua lub limtiam, kom tsim tau txawm tias ya raws thiab roughen lub tsho tiv no nrog nplej xuab zeb (zoo dua o)
Yav tag los, cov noob ib leeg tsuas yog muab tso rau hauv cov txheej hauv substrate thiab feem ntau muab tso rau sab nraum zoov. Txawm li cas los xij, stratification yuav ua tau zoo dua yog tias qhov kub thiab txias tsis tu ncua. Sab nraum zoov, piv txwv li, ib hnub tshwj xeeb tshav ntuj los yog lub caij sov thaum lub caij nplooj zeeg lossis caij nplooj ntoos hlav tuaj yeem ua rau lub sijhawm ntev.
Tip:
Kev siv cov substrate rau cia ua haujlwm, ntawm ib sab, khaws cov dej noo. Tsis tas li ntawd, nws kuj muab qee theem ntawm kev tiv thaiv kab mob thiab lwm yam kab mob phem. Yog li ntawd, tsis txhob siv humus los yog vaj av, vim hais tias ob qho tib si tshuaj muaj cov qib siab ntawm cov tshuaj uas yuav tsum tau zam.
Special case: Frost germinator
Frost germinators sawv cev rau ib daim ntawv tshwj xeeb ntawm kev txias txias. Tsis tsuas yog koj xav tau txias txias, koj xav tau tiag tiag Frost. Cov txheej txheem sib raug rau qhov txias stratification. Txawm li cas los xij, qhov ntsuas kub zoo tshaj plaws ntawm no tsuas yog qis dua 0 degrees mus rau ib puag ncig rho tawm 5 degrees Celsius.
Stratification nrog mechanical germination inhibition
Thaum kawg, dab tsi tseem tshuav yog ib hom kev sib xyaw ntawm cov khaub thuas stratification twb tau tham thiab ib daim ntawv ntxiv kom kov yeej cov germination inhibitions. Cov neeg kho tshuab inhibition uas tam sim no qhov kev tsom xam feem ntau yog nrog cov neeg xa xov chemical uas tuaj yeem tawg los ntawm lub caij txias. Qhov no yog vim li cas peb hais txog qhov hu ua sov-txias stratification, txij li lub npe hu ua txias stratification yog ua ntej los ntawm lub caij sov.
Application for
Seed duab nrog lub plhaub tawv
Inhibition txheej txheem
- Mechanical barrier ntawm cov noob lub tsho tiv thaiv germination-stimulating influences, xws li tshav kub thiab noo noo
- Nyob rau hauv noo noo nkag mus rau hauv lub tub ntxhais vim lub siab tsis kam ntawm lub plhaub
- Lub ntsiab lus ntawm kev ncua los ntawm lub sijhawm ntawm o ntawm lub tsho tiv no, germination tsuas yog ua tau tom qab o thiab tawg
txheej txheem tshem tawm qhov inhibition
- Kev npaj ntawm tus kheej cov noob raws li rau txias stratification nrog rau embedding nyob rau hauv substrate
- Thawj qhov chaw nrog qhov kub thiab txias ntawm 20 degrees Celsius lossis siab dua me ntsis
- Lub sij hawm nyob ib ncig ntawm 2 mus rau 4 lub lis piam
- Effect: sai dua o thiab tawg ntawm cov noob txheej
- txo qhov kub los yog hloov qhov chaw xws li txias stratification
