Cov nroj tsuag loj hlob twg yuav tsum tau siv rau cov noob hnav los txhawb kev cog qoob loo thiab germination?

Rau cov noob hnav khaub ncaws tsom rau kev txhawb nqa cov cag thiab germination, peb pom zoo kom siv Brassinolide, Gibberellic Acid (GA₃), thiab Sodium Nitrophenolates. Cov nroj tsuag kev loj hlob regulators zoo ua txhaum cov noob dormancy, nce germination tus nqi, thiab txhawb kev loj hlob hauv paus system, uas ua rau ib tug uniform thiab robust loj hlob.

1. Brassinolide
Nws ua haujlwm los txhawb cov noob germination, ceev cov hauv paus hniav, thiab txhawb kev tsim cov hauv paus hniav zoo, thaum tib lub sijhawm txhim kho cov yub 'tiv taus rau txias thiab drought.

Daim Ntawv Thov: Rau txhua lub mu (kwv yees 0.067 hectares) ntawm thaj av, sib tov 5-10 ml ntawm 0.01% Brassinolide soluble kua nrog 200-300 ml dej rau dilution. Ua tib zoo sib tov cov tshuaj no nrog cov noob - xws li cov nplej los yog pob kws - cia lawv rau huab cua qhuav, thiab tom qab ntawd pib nrog kev cog qoob loo.

Cov txiaj ntsig: ** Qhov tseem ceeb txhawb qhov tshwm sim; ua rau lub hauv paus tsim ntau dua thiab sib xws, kev loj hlob zoo thaum lub sij hawm yub.


2. Gibberellik Acid (GA3)
Nws muaj peev xwm rhuav tshem cov noob dormancy, stimulating coleoptile elongation, thiab txhawb germination. Nws yog tshwj xeeb tshaj yog haum rau siv nrog cov laus noob los yog thaum sowing nyob rau hauv qis-kub ib puag ncig.

Daim Ntawv Thov: Rau cov qoob loo xws li nplej thiab barley, tsau cov noob hauv 1 mg/kg GA3 tov rau 6-12 teev; rau qos yaj ywm tubers, soak hauv 0.5-1 mg / / kg tov rau 30 feeb.

Lus Cim: Cov concentration ntau dhau tuaj yeem ua rau etiolation (qhov txawv txav qia elongation); yog li ntawd, cov koob tshuaj yuav tsum tau tswj nruj me ntsis.

3. Sodium Nitrophenolates (Atonik)
Nws lov dormancy, txhawb cov hauv paus kev loj hlob thiab seedling vigor, thiab txhim kho uniformity ntawm seedling tshwm sim. Nws yog qhov tshwj xeeb tshaj yog rau cov noob uas raug kev ntxhov siab tsawg.

Daim Ntawv Thov: Npaj 6000-fold dilution ntawm 1.8% Atonik tov; soak cov noob nyob rau hauv cov tshuaj no rau 12 teev, cia lawv mus rau huab cua qhuav, thiab ces sow.

Qhov zoo: Sodium Nitrophenolates (Atonik) tuaj yeem sib xyaw nrog cov tshuaj fungicides, muab ob qho txiaj ntsig ntawm kev tiv thaiv kab mob thiab kev txhawb nqa kev loj hlob.
