Tillering yog tsim los ntawm sab tua. Nws tso cai rau zus tau tej cov stems, pib los ntawm ib tug thawj yub. Qhov no ua rau kom nruj tufts thiab ntau lub taub hau.

Tillering yog ib qho khoom sib koom los ntawm ntau cov qoob loo.

Txoj kev xav

Txhua cov cereals muaj ntau tus cultivators (sab ceg). Tillering yog ib qho tseem ceeb agronomic yam ntxwv uas ua qauv rau yav tom ntej tua. Thaum loj hlob nyob rau hauv kev sib cais, cov txheej txheem no yog heev dynamic thiab tsim tau. Thaum loj hlob nyob rau hauv tej yam kev mob ntawm high ntom, tillering ntawm cereals slows down. Nyob rau tib lub sijhawm, ib tsob nroj tuaj yeem tsim tau ib tus neeg cog qoob loo xwb.

Meaning

Tillering yog lub sijhawm kom tau txais txiaj ntsig siab tshaj plaws. Tus naj npawb tsis txaus ntawm cov cultivators yuav txwv qhov kev loj hlob tag nrho ntawm cereals. Kev tua ntau dhau yuav siv cov peev txheej cog thiab av noo. Qhov no kuj yuav ua rau kom qis yields. Cov nplej me me yuav nce ntxiv.

Yog li, tillering pab cov nyom nyom hloov mus rau qhov sib txawv ib puag ncig. Nws kuj tso cai rau koj ua qauvcog architecture nyob rau hauv ntau yam kev zov me nyuam.

Type of tillering

Nws muaj peb txoj hauv kev los tsim cov paj thiab tua tshiab:

  1. Rhizomatous. Qhov no yog txoj kev loj hlob ntawm ob peb tua los ntawm ib lub ntawm. Lawv loj hlob perpendicular mus rau lub ntsiab qia. Lawv nyob hauv av. Qhov tob - txog li 5 cm. Ntxiv rau qhov tua, txhua qhov ntawm cov rhizome tsim cov hauv paus tshiab. Nyiam lub teeb, xoob, xuab zeb av.
  2. Nplua nuj. Kev tua yog nyob hauv av. Loj hlob ntawm lub kaum sab xis mus rau lub ntsiab qia. Ib tug tua tshwm los ntawm ib tug internode. Xws li tillering contributes rau tsim ib tug xoob Bush. Haum rau txhua yam av.
  3. Txoj hav txwv yeem. Cov nodes yog nyob rau saum npoo av. Qhov no ua kom zoo aeration thiab qib siab ntawm cov av noo nyob rau hauv thaj tsam ntawm lub hav txwv yeem. Txhua qhov node tsim tua, uas muaj lawv tus kheej node. Cov sprouts yog qhia upwards. Lub hav txwv yeem yog tsim tuab thiab muaj zog. Cov nroj tsuag loj hlob nyob rau hauv waterlogged, fine-grained av.

txheej txheem kev cog qoob loo

Ntawm txhua yam paub txog tillering cereals, qhov no yog qhov zoo tshaj plaws.

  1. Nqa 5-10 cov nroj tsuag ib puag ncig. Qhov zoo tshaj plaws, khawb lawv es tsis txhob rub lawv kom tsis txhob ua rau cov hauv paus hniav thiab nplooj.
  2. Rau qhov kev kwv yees nrawm tab sis ntxhib ntawm qhov tseeb tillering, khoov cov nplooj nyob rau hauv qhov sib txawv ntawm lawv qhov kev loj hlob ib txwm.
  3. Tam sim no koj yuav tsum ntsuas qhov kev ncua deb ntawm cov nodes los ntawm cov nplooj loj hlob. Los ntawm thawj mus rau thib obQhov deb ntawm node yuav tsum yog 1 cm. Los ntawm qhov thib ob mus rau qhov thib peb - tsis ntau tshaj 2 cm. Cov node tej zaum yuav qis dua cov av theem. Tab sis yog tias qhov tob tsis tshaj 1 cm, tillering yog suav tias yog ib txwm.

Tom qab qhov kev ntsuam xyuas ntawm tag nrho cov yub, kev ntsuas yuav tsum tau coj los ua kom tus qauv ntawm cov cereals yav tom ntej

Yuav ua li cas

Thaum cov qoob loo cog qoob loo ib leeg, tus nqi ntawm nplooj nplooj photosynthesis txo. Qhov no cuam tshuam rau txhua theem ntawm kev loj hlob ntawm cov nroj tsuag, uas yog tillering. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau soj ntsuam qhov kev ncua deb ntawm cov nplej thaum cog. Muaj kev cai rau ntau hom av. Yog hais tias qhov kev ncua deb ntawm cov nroj tsuag yog tsawg tshaj li 1 cm, nws yog tsim nyog los txiav tawm cov nroj tsuag. Yog hais tias qhov deb tshaj 2 cm, ces sow ntau densely.

Tseem muaj txoj hauv kev cuam tshuam rau tillering ntawm twb sown teb.

Nitrogen Nyob

Kev siv ntxiv ntawm cov chiv no yuav pab tau thaum muaj pes tsawg cov nroj tsuag thiab tua tsawg. Tsis tas li ntawd, nitrogen tuaj yeem cuam tshuam kev loj hlob ntawm cov ceg ntoo thiab cuam tshuam rau kev tsim cov cytokinins. Cov ntaub ntawv tshawb fawb tam sim no qhia tau tias tus qauv siv tus nqi ntawm nitrogen yog nruab nrab ntawm 120 thiab 150 kg ib hectare ntawm av.

phosphorus

txwv cov av phosphorus ua rau txo qis ceg. Ua los ntawm kev hloov tshuaj hormones, nws txhawb kev tsim khoom thiab thauj ntawm strigolactone hauv cov nroj tsuag.

Sulfur thiab manganese

Cov tshuaj no muaj txiaj ntsig zoo nyob rau theem pib ntawm kev loj hlob ntawm cov nroj tsuag. Manganese thauj lub zog rau photosynthesis. Sulfurcatalyzes tag nrho cov enzymatic systems ntawm cereal qoob loo.

tswj hwm hormonal

Ib txoj kab ke ntawm kev sib cuam tshuam hormonal tswj kev tsim cov ceg feem ntau. Rau qhov loj, tillering yog tswj los ntawm kev taw qhia los ntawm cov tshuaj hormones: auxin, strigolactone, thiab cytokinin. Rau kev tswj hwm hormonal, nws yog qhov tsim nyog los siv cov txheej txheem xws li biosynthesis, thauj thiab rhuav tshem cov tshuaj hormones.
