Recommended Plant Growth Regulators for Rapeseed Cultivation

Cov nroj tsuag kev loj hlob regulators pom zoo siv thaum lub sij hawm kev loj hlob voj voog ntawm rapeseed (canola) feem ntau muaj xws li Paclobutrazol (Paclo), Uniconazole, Brassinolide, thiab DCPTA. Lawv lub luag haujlwm tseem ceeb yog tswj hwm kev loj hlob ntau dhau, tiv thaiv chaw nyob, txhawb nqa ceg, txhim kho kev ntxhov siab, thiab ua kom muaj txiaj ntsig zoo.

Los ntawm kev tshawb fawb xaiv regulators raws li lub cev xav tau ntawm rapeseed ntawm ntau theem kev loj hlob, cov neeg cog qoob loo tuaj yeem ua tiav cov txiaj ntsig siab ntawm kev tsim "cov noob muaj zog, muaj zog stems, ntau paj, thiab cov pods puv." Cov hauv qab no qhia txog cov phiaj xwm qhia txog theem tshwj xeeb:

I. Kauj Ruam 3–6 Nplooj: Cultivating yub zoo; Tswj kev loj hlob ntau dhau thiab txhawb kev loj hlob hauv paus

Lub hom phiaj tseem ceeb nyob rau theem no yog los tiv thaiv "leggy" seedlings (ntau qia elongation) thiab txhim khu kev mob khaub thuas thiab drought, yog li tso lub hauv paus ruaj khov rau kev nyab xeeb overwintering.

Paclobutrazol (Paclo)
Inhibits ntau elongation ntawm stems thiab nplooj, thaum txhawb thickening ntawm qia hauv paus thiab robust hauv paus system kev loj hlob.
** Lub Sijhawm Daim Ntawv Thov:** Thaum lub sijhawm 3-5 nplooj ntawv, lossis 7 hnub ua ntej hloov pauv.
** Pom zoo noj: ** 40-60 grams ib * mu * ntawm 15% Paclobutrazol Wettable Powder, diluted nyob rau hauv 30-40 kilograms dej rau foliar txau.
** Yield Enhancement: ** tuaj yeem nce yield los ntawm 8% -12%, thaum txhim kho qhov chaw nyob.

Uniconazole
Muaj kev ua haujlwm lom neeg ntau dua thiab yuav tsum tau siv qis dua; haum rau dryland rapeseed cultivation los yog teb uas txo cov tshuaj residues yog qhov tseem ceeb.
** Pom zoo noj: ** 30-45 grams ib * mu * ntawm 5% Uniconazole formulation, diluted nyob rau hauv dej rau uniform foliar spraying.

Brassinolide / Diethyl aminoethyl Hexanoate (DA-6)
Haum rau cov teb uas tsis muaj zog seedlings; txhawb txoj kev loj hlob thiab accelerates txoj kev hloov mus rau ib tug robust yub theem.
** Muab tswv yim sib xyaw:** Sib tov tshuaj tsuag nrog Monopotassium Phosphate los txhim kho kev ntxhov siab.


II. Budding thiab Bolting Stage (Stem qhov siab: 5-15 cm): Tswj kev loj hlob thiab tiv thaiv chaw nyob; Txhawb nqa ceg
Cov theem no qhia txog kev hloov pauv tseem ceeb ntawm kev loj hlob vegetative mus rau kev loj hlob ntawm kev loj hlob. Tswj kev loj hlob ntau dhau ntawm cov nroj tsuag tiv thaiv ntxov ntxov bolting thiab flowering, thaum txhawb cov ceg sib txawv.

Paclobutrazol (Paclo)
** Lub Sijhawm Zoo Tshaj Plaws: ** Thaum ntxov bolting theem (kab qhov siab: 5-10 cm).
**Function:** Inhibits the etiolation (leggy loj hlob) ntawm lub ntsiab qia, nce tus naj npawb ntawm cov ceg zoo los ntawm 2-3, thiab boosts pod ntom los ntawm 20%.
** Cov qauv pom zoo: ** 50-60 g ntawm 15% Paclobutrazol + 100 g ntawm 99% Monopotassium Phosphate ib 15-20 catties (30-40 * jin *) ntawm dej. Siv cov tshuaj tsuag foliar 2-3 zaug, nrog lub sijhawm ntawm 10-15 hnub ntawm daim ntawv thov.

Brassinolide
Nws tuaj yeem siv ua ke nrog Paclobutrazol txhawm rau txo qhov kev loj hlob inhibition tshwm sim los ntawm kev loj hlob-tswj kev kho mob thiab txhim kho photosynthetic efficiency.

III. Flowering mus rau Pod-Setting Stage (Early Flowering - Peak Flowering): Khaws paj thiab Pods; Tiv thaiv Premature Senescence
Lub hom phiaj thaum lub sij hawm no yog los txhim kho pollination zoo, tiv thaiv "dig muag paj" (paj uas tsis teem pods), thiab tiv thaiv ntxov ntxov ripening induced los ntawm high kub.

Brassinolide + Monopotassium Phosphate + Boron Fertilizer
Ua raws li "Ib qho Kev Txhawb Nqa, Plaub Kev Tiv Thaiv" lub tswv yim: Txhawb kev loj hlob; tiv thaiv kab tsuag thiab kab mob; tiv thaiv ntxov ntxov senescence; tiv thaiv qhov muag tsis pom paj; thiab tiv thaiv ntxov ntxov ripening tshwm sim los ntawm kub kub.
** Lub Sijhawm Pom Zoo: ** Thov ib zaug thaum lub sijhawm paj tawg thaum ntxov (thaum 20% ntawm paj tau qhib) thiab ib zaug thaum lub sijhawm paj tawg paj (thaum 50% paj tau qhib).
**Fungicide Combination:** tuaj yeem sib xyaw nrog cov tshuaj fungicides xws li Prochloraz lossis Procymidone los tiv thaiv Sclerotinia qia rot.

DCPTA
Muaj feem xyuam los ntawm lub paj-stalk theem mus txog rau thaum ntxov flowering theem, nws ua ncaj qha rau ntawm lub cell nucleus los txhim kho photosynthetic efficiency, yielding ib tug ntsuas nce nyob rau hauv qoob loo zus tau tej cov 15% -25%.

IV. Ua ntej pib ntawm Frost puas los yog ib puag ncig kev nyuaj siab: Txhim kho kev nyuaj siab
10-15 hnub ua ntej tuaj txog ntawm qhov kub thiab txias, siv cov tshuaj tua kab mob ntawm Brassinolide, dej-soluble amino acid chiv los txhawb Frost tsis kam.
Nyob rau hauv qhov tshwm sim ntawm Frost puas tsuaj: Tam sim ntawd siv cov tshuaj tsuag fungicide los kaw cov qhov txhab, thiab siv nrog rau cov nroj tsuag kev loj hlob regulator los pab kom rov zoo.
