GA3, Gibberellin 90% TC gibberellic acid, cog kev loj hlob regulator, agrochemical 10% SP 20% SP
Taw qhia
Gibberellin GA3 yog cov khoom siv cog kev loj hlob tshaj plaws hauv kev ua liaj ua teb, hav zoov thiab horticulture hauv Suav teb.
Lub physiological functions ntawm gibberellin GA3 feem ntau muaj xws li: hloov qhov feem ntawm cov poj niam thiab txiv neej paj nyob rau hauv ib co qoob loo, inducing parthenocarpy, accelerating txiv hmab txiv ntoo loj hlob thiab txhawb cov txiv hmab txiv ntoo;rhuav tshem cov noob dormancy, thaum ntxov noob germination, accelerating qia elongation thiab mossing ntawm tej qoob loo;Kev loj hlob ntawm nplooj nplooj thiab accelerating txoj kev loj hlob ntawm cov tub ntxhais hluas ceg yog tsim nyog rau tsub zuj zuj ntawm metabolites nyob rau hauv phloem thiab qhib cambium;Inhibit maturation thiab senescence, tswj lateral bud dormancy thiab tuber tsim.

Daim ntawv thov
2.1 Yuav kom tau txais txiaj ntsig zoo li cas?
Lub luag haujlwm tseem ceeb tshaj plaws ntawm gibberellin yog txhawm rau ua kom cov cell elongation (gibberellin tuaj yeem ua kom cov ntsiab lus ntawm auxin hauv cov nroj tsuag, thiab auxin ncaj qha tswj cov cell elongation).Nws kuj txhawb kev faib cell.Nws tuaj yeem txhawb nqa cell expansion (tab sis tsis ua rau acidification ntawm cell phab ntsa).Tsis tas li ntawd, gibberellin tuaj yeem cuam tshuam kev loj hlob, lateral bud dormancy thiab aging, Physiological muaj nuj nqi ntawm tuber tsim.
2.2 Yuav siv li cas rau cov qoob loo?
Gibberellin yog tsim rau cov qoob loo hauv qab no: paj rwb, txiv lws suav, qos yaj ywm, txiv hmab txiv ntoo ntoo, nplej, nplej, taum pauv thiab haus luam yeeb los txhawb lawv txoj kev loj hlob, germination, flowering thiab fruiting;Nws tuaj yeem txhawb kev loj hlob ntawm cov txiv hmab txiv ntoo, txhim kho cov noob qoob loo, thiab muaj cov txiaj ntsig tseem ceeb ntawm paj rwb, zaub, melons thiab txiv hmab txiv ntoo, nplej, zaub ntsuab, thiab lwm yam.
2.3 Dosage thiab siv
| Cov qauv tsim | Cov npe qoob loo | Tswj khoom | Noj | Txoj kev siv |
| 10% TB | mov | Tswj kev loj hlob | 150-225 g / h | Nplooj tsuag |
| zaub celery | Tswj kev loj hlob | 1500-2000 zaug ua kua | tshuaj tsuag | |
| 10% SP | zaub celery | Tswj kev loj hlob | 900-1000 zaug ua kua | tshuaj tsuag |
| Citrus tsob ntoo | Tswj kev loj hlob | 5000-7500 zaug ua kua | tshuaj tsuag | |
| 20% SP | mov | Tswj kev loj hlob | 300-450 g / h | Chav thiab nplooj txau |

1. gibberellic acid yog me me nyob rau hauv dej solubility, yaj nrog ib tug me me npaum li cas ntawm cawv los yog Baijiu ua ntej siv thiab dilute nws mus rau qhov xav tau concentration.
2. Cov noob tsis muaj menyuam ntawm cov qoob loo kho nrog gibberellic acid nce, yog li nws tsis tsim nyog siv tshuaj hauv thaj chaw tshwj tseg.
