Rau dab tsi yog vim li cas seedlings ntawm txiv lws suav ncab tawm thiab yog dab tsi yog qhov no tshwm sim?

Loj hlob zoo zoo lws suav seedlings yog ib txoj kev ua haujlwm ntawm kev tsim kom muaj kev haum siab rau nws, noj nyiaj rau hauv cov huab cua kub, huab cua sov, dej caij thiab ntau lwm yam.

Qee lub sij hawm lws suav seedlings nyob rau hauv lub tsev ua dhau lawm ntev thiab nyias, thiab yog hais tias koj tsis paub dab tsi ua li cas nyob rau hauv xws li mob, koj muaj peev xwm ua puas tag nrho cov seedlings.

Kev cai yooj yim ntawm kev saib xyuas cia koj kom tiv thaiv seedlings los rub lub stems, thiaj li hais tias lawv loj hlob zoo, fluffy thiab ruaj khov.

Dab tsi yog rub cov txiv lws suav txhais li cas thiab nws ua tau dab tsi?

Rub ib tug seedling lws suav yog lub elongation thiab simultaneous thinning ntawm stalks ntawm seedlings, dab tsi tshwm sim nyob rau hauv ib lub sij hawm luv luv yog tias tsis ua raws li cov cai ntawm kev saib xyuas. Nyob rau hauv cov ntaub ntawv no, los ntawm lub sij hawm lub seedlings yog cog, nws tsis compact, muaj zog seedlings uas hlob, tab sis taus, nyias thiab sluggish tua uas muaj ib tug ntev long qev uas loses stability thiab tsis tuav upright.

Rooting ntawm xws li seedlings yog significantly inhibited, thiab rooted nroj tsuag maj mam, lawv tsis Bloom zoo thiab dais txiv hmab txiv ntoo pluag.

Vim li cas

Lws suav seedlings yog rub tawm raws li ib tug ntawm kev ua txhaum ntawm lub qauv ntawm kev saib xyuas. Cov laj thawj yuav yog cov nram qab no:

1. Tsis tshua muaj teeb pom kev zoo. Los ntawm lub sij hawm lub noob uas sown, tus nroj tsuag yuav tsum zoo hnub ci. Rau txiv lws suav, sab qab teb yog nyiam. Lawv tsis pom zoo kom muab tso tawm ntawm qhov kaj qhov rais (qhov rais). Thaum qhaj ntawv tsis pom kev, lub yub yuav raug qeeb thiab tsaus nti, kos tawm sai sai hauv ib lub lim tiam.
2. Tsis ua raws li qhov kub thiab txias. Seedlings ntawm txiv lws suav xav tau ib tug huab cua sov huab cua. Nruab hnub nruab hnub yuav tsum tsis pub dhau 18-25 degrees, hmo ntuj - 14-16 degrees. Thaum lub ntsuas kub siab dhau heev lawm los yog tsis tshua muaj siab, lub caij nplooj ntoos zeeg raug muab coj tawm thiab muab me ntsis foliage.
3. Irrigation ntshawv siab. Lws suav sprouts yog rub tawm nrog ntau heev watering, yog li lub seedlings nce hauv paus system thiab tiv thaiv lawv tus kheej los ntawm rotting.
4. Dhia txav kom haum ua rau ib tug tsis muaj qhov tsis zoo ntawm qhov chaw, tab sis tseem lub teeb thiab kev muab kev pab cuam. Seedlings pib thaiv txhua lwm yam, lawv foliage crushes. Qhov no ua rau ib tug gradual elongation ntawm stems ntawm seedlings, uas ua tsis ncaj thiab nyias, tej zaum yuav poob.
5. Kev muab tshuaj ntau dhau hauv particular, nitrogen thiab phosphorus. Kho tsis zoo ntawm chiv los yog tsis xaiv av, uas yog tsis tsim nyog rau txiv lws suav los ntawm tus xov tooj ntawm kab kawm, ua rau ib tug sai ncab ntawm seedlings thiab ib qho tseem ceeb underdevelopment ntawm hauv paus system. Thaum transplanting mus rau ib qho chaw mus tas li, xws li seedlings feem ntau tsis muaj peev xwm paus.
6. Tsis muaj poov tshuaj nyob rau hauv cov av. Ib tug tsis muaj poov tshuaj yog cai thaum npaj cov av ntawm nws tus kheej los ntawm gardeners, zoo li siv qub, av nplaum los yog av av. Nyob rau hauv rooj plaub no, lub seedlings yog stretched heev ntseeg, thiab cotyledon nplooj yog high school.
7. Ua txhaum ntawm lub sij yawm ntawm cog seedlings. Tshwm sim thaum sowing noob dhau los los yog nyob rau hauv ib qho kev nyab xeeb tsis zoo, thaum seedlings tsis tau cog rau hauv av qhib nyob rau lub sij hawm pom zoo. Nyob rau hauv lub neej yav tom ntej, xws li seedlings tej zaum yuav tsis Bloom thiab tuag.
8. Ntau tob cog noob. Nws ua rau lub fact tias seedlings heev ntev tuaj rau hauv av saum npoo thiab ntxiv mus rau loj hlob elongated nyob rau hauv lub neej yav tom ntej.

Yuav ua li cas loj hlob seedlings nyob rau hauv lub tsev thiaj li hais tias lawv tsis ncav siab li?

Yuav kom seedlings tsis stretched, nws yog pom zoo kom ua raws li ib co kev cai:

1. Sowing noob ncaj qha nyob rau hauv lub sij hawm teev nyob rau hauv cov lus qhia nyob rau hauv lub ntim ntawm noob (nyob rau hauv lig Lub ob hlis ntuj los yog thaum lub peb hlis ntuj). Nyob rau hauv cov nyom climatic puag, nws yog preferable siv thaum ntxov ntau yam uas yuav muaj lub sij hawm mus los ntawm lawv cov loj hlob rau lub caij.
2. Tsis txhob tuaj lig nrog transplanting seedlings mus rau ib qho chaw mus tas li.
3. Siv rau cog cov noob tsis zoo uas tsis tau tso cai.
4. Xav txog lub sij hawm ntawm daylight rau qhov chaw ntawm seedlings.
5. Siv ib qho tsim substrate rau txiv lws suav, uas yuav tsum tau xoob, tsis zoo thiab zoo drained.
6. Thov cov pob zeb hauv av chiv hauv kev yug me nyuam. Yog hais tias lub fertilizer yog npaj los ntawm txhais tes, ces siv peat, compost thiab av nyob rau hauv qhov ratio ntawm 3: 2: 1.
7. Los tuav kev li niaj zaus ywg dej, tab sis kom tsis txhob muaj cov kab hauv cov av. Txiv lws suav nyiam ntau tshaj, tab sis tsis tshua ywg dej nrog tag nrho los sis yuav luag txhua qhov kom qhuav ntawm cov av es tsis txhob muaj dej me me txhua hnub. Dej yuav tsum tau sib cais thiab sov, tsis qis dua 30 degrees. Dej ntawm seedlings yog nqa tawm 1 lub sij hawm nyob rau hauv 3-4 hnub (thaum nplooj pib mus rau lub caij nplooj ntoos zeeg nyob rau ntawm seedlings).
8. Xav txog hom ntau yam (ntxov, nruab nrab-caij nyoog los sis lig).
9. Lawv tsis siv thaj av cog qoob loo, nyob rau hauv uas lub nightshade (eggplants, qos yaj ywm, txiv lws suav) tau loj hlob rau yav dhau los 3 xyoo.
10. Ua ntej sowing, lub noob yog soaked nyob rau hauv ib hnub nrog ib tug qaug zog daws ntawm poov tshuaj permanganate (1: 5000). Nyob rau hauv dilution nrog dej, poov tshuaj permanganate muab tawm poov tshuaj, uas yog tsim nyog rau seedlings rau me ntsis kev loj hlob.
11. Noob yog sown mus rau ib tug tob ntawm tsis ntau tshaj 1.5 centimeters.
12. Tom qab sowing, lub noob uas them nrog ntawv ci. Sov sov contributes rau txoj kev loj hlob zoo ntawm seedlings (kub 22-25 degrees).
13. Nco ntsoov tshem tawm cov movie tom qab rov tshwm sim ntawm tua - ces lawv paus system yuav pib tsim. Yog hais tias qhov no tsis ua tiav, lub seedlings yuav loj hlob elongated, kev sib tw thiab nrog luv luv keeb kwm keeb kwm.
14. Txij li thaum lub seedlings yog kos tawm nyob rau hauv ib qho tsis tshua sov chaw, lawv yuav tsum tsis txhob muab tas li nyob rau sab saum toj, nyob qhov twg cov huab cua kub yog me ntsis siab dua. Thaum lub sij hawm kev loj hlob ntawm lub keeb kwm, nws yog zoo dua mus rau txo lub crates los yog khob rau hauv pem teb.
15. Tom qab tshwm sim ntawm 2-3 tseeb nplooj ntawm ib tug seedling, nws dives, lub ntim uas tau sau nrog ib tug nutrient substrate, lub keeb kwm ntawm cov nroj tsuag yog me ntsis shortened thiab faus los ntawm 1.5-2 cm. Rau peb lub sij hawm, txiv lws suav dive tom qab 3 lub lis piam, sau lawv nrog lub ntiaj teb mus rau thawj qhov tseeb nplooj.

    Rov qab tuaj yeem pab ntxiv rau txoj kev loj hlob ntawm lub hauv paus system thiab tiv thaiv kev ncab.

Yuav ua li cas yog tias saplings ua nyias thiab ntev?

Ntxiv teeb pom kev zoo

Nrog ib tug tsis muaj teeb, seedlings yog nqa tawm on glazed lawj. nyob rau sab qab teb sab (pub sab qab teb-sab hnub tuaj, sab qab teb-sab hnub poob) lossis nruab teeb. Fluorescent teeb tau muab tso rau ntawm ib tug deb ntawm 5-6 cm los ntawm saum nplooj ntawv sau ntawm seedlings.

Kub hloov

Txo qhov ntsuas kub mus rau 15-16 degrees nres qhov kev loj hlob ntawm seedlings thiab yog ib qho zoo kev ntsuas los pab lub seedlings, raws li nws xav tau cua sov nkaus xwb rau thawj zaug. Thaum lawv tuaj tos, lawv cia sov sov, tom qab uas lawv rov txo kom txog 15 degrees.

Deepening

Nyob rau tib lub sij hawm, nroj tsuag dived mus rau hauv nyias ntim, muab qhov stems mus rau hauv av mus rau ib qhov tob ntawm 3-4 cm, los yog los ntawm deepening lub seedling nyob rau hauv ib tug tilted txoj hauj lwm (nws qhov chaw saum npoo yuav tsum nyob twj ywm ntsug). Yog hais tias lub seedlings yog stretched tawm nyob rau hauv tus neeg ntim, ces hauv av yog sau mus rau nws nyob rau hauv xws li ib txoj kev uas cov av txheej tsis ncav lub cotyledon tawm 2-3 cm.

Watering hom

Dej lub seedlings tsis tu ncua: thawj zaug ib lub lim tiam, tom qab ntawd ces txhua txhua 3 hnub. Siv dej sov. Txwv nrog dej txias ua rau rotting ntawm keeb kwm. Yog hais tias cov av yog ntub, thiab nplooj ntawm seedlings yog sluggish thiab drooping, lub seedlings yuav tsum tsis txhob tau watered - nws yuav tsum tau tsiv mus rau ib qho chaw tiv thaiv los ntawm ncaj qha tshav ntuj kom txog thaum cov av yog kom qhuav. Tom qab ntawd, cov dej tau ua txhua zaus.

Pub Noj

Rau stretched lws suav seedlings tsis siv nitrogen chiv, uas pab mus ntxiv ncab ntawm stems. Cov tshuaj yaj yeeb thiab phosphate chiv, tshauv (20 grams ib 200 ml ntawm dej) yog nyiam. Yog hais tias, ua ke nrog lub ncab, lub seedlings ua daj ntseg, ces urea yog ntxiv rau fertilizer ntawm tus nqi ntawm 20 grams ib 10 liv thiab lub seedlings yog muab tshem tawm rau ib lub lim tiam nyob rau hauv ib qhov chaw txias (10 degrees Celsius).

Seedling kev loj hlob yuav qeeb, thiab foliage yuav tig ci ntsuab. Ua ntej yuav poob siab, seedlings yuav tsum tau sprayed nrog ib tug daws ntawm ntshav nrog iodine. (5 tee ntawm iodine, 200 ml ntawm ntshav dej, 1 liter dej).

Kev Kho Mob Hlwb Kev Kho Mob

Kev loj hlob regulators yog siv ob zaug ("Heteroauxin", "Zircon", "Biosil", "Emistim", "Reggae") thaum lub caij pom ntawm ob kab lus tseeb thiab 2 lub lis piam tom qab, ntxiv fertilizer rau hauv paus thiab tsis ntog ntawm nplooj.

Tshem tawm ntawm cotyledon nplooj

Cotyledon nplooj yog thawj nplooj ntawm seedlings uas muaj ib tug elongated oval duab. Lawv nphav tau zoo ua rau cov nroj tsuag loj hlob thiab ua kom muaj zog ntxiv. Nws yog zoo dua kom tshem tawm cov cotyledon nplooj nrog txiab thiaj li tsis txhob puas cov muag heev stems. Koj tuaj yeem rho tawm lawv tig: daim ntawv thib ob ntawm ib lub lim tiam tom qab thawj zaug. Qhov no yog tsim rau tsuas yog thaum ntxov seedlings.

Pinching

Pinching yog txiav saum ntawm lws suav seedlings nrog 5-6 tseeb nplooj ntxiv nyob rau hauv lub qia. Txiav qhov taub yuav muab tso rau hauv dej rau 7-10 hnub rau qhov tsos ntawm keeb kwm, thiab ces cog rau hauv av. Txiav seedlings sai sai muab tshiab tua nyob rau hauv qhov kev txiav cut.

Thaum qhov loj ntawm kev tua tshaj 5 cm, 2 qaum cov theem qauj nyob sab qaum, tshem tag nrho lwm tus. Pruning ntawm stepsons yog nqa tawm ncaj qha 3 lub lis piam ua ntej cog lub seedlings mus rau ib tug mus tas li qhov chaw.

Yog tsis ua raws li cov kev cai ntawm txoj kev saib xyuas ua rau kom sai thinning thiab lengthening ntawm lws suav seedlings. Muaj ntau txoj kev los tiv thaiv txoj hauv kev no, muab cov yam ntxwv ntawm cov nroj tsuag nws tus kheej thiab cultivation agrotechnical txujci. Yog hais tias lub rub tsis tshwm sim, gardeners muaj txhua lub caij nyoog los cawm lub seedlings siv yooj yim thiab pheej yig txoj kev.
