Prohexadione calcium yog cov nroj tsuag kev loj hlob regulator uas zoo tswj cov vegetative kev loj hlob ntawm cov qoob loo xws li rapeseed los ntawm inhibiting lub synthesis ntawm gibberellins nyob rau hauv cov nroj tsuag, li no pab txhawb qhov chaw nyob tsis kam thiab txhawb nce yield.
Cov teebmeem tseem ceeb ntawm Prohexadione calcium:
1. Tswj kev loj hlob ntau dhau thiab txhim kho qhov chaw nyob tsis kam: Prohexadione calcium tuaj yeem ua kom luv luv ntawm internode ntev ntawm rapeseed stems, ua rau cov stems thicker thiab muaj zog, txo cov nroj tsuag qhov siab, thiab txo qhov kev pheej hmoo ntawm chaw nyob los ntawm cua thiab los nag.
2. Txhawb nqa kev loj hlob thiab nce yield: Thaum inhibiting ntau qia thiab nplooj loj hlob, Prohexadione calcium tuaj yeem txhawb kev sib txawv ntawm paj paj, nce cov txiv hmab txiv ntoo, thiab txhawb nqa pod txoj kev loj hlob thiab cov noob sau, yog li nce yield rau ib cheeb tsam.
3. Txhim kho cov nroj tsuag kev noj qab haus huv: Tus neeg sawv cev no tuaj yeem ua kom cov ntsiab lus chlorophyll, ua rau cov nplooj ntsuab thiab thicker, thiab txhim kho photosynthetic efficiency; Nyob rau tib lub sijhawm, nws txhawb txoj kev loj hlob hauv paus thiab txhim kho kev nqus cov as-ham, pab txhawb kev loj hlob ntawm cov nroj tsuag noj qab haus huv.
4. Txhim kho kev ntxhov siab: Prohexadione calcium tuaj yeem txhim kho qhov kam rau ntawm rapeseed rau abiotic stresses xws li drought thiab kub tsis tshua muaj, thiab rau qee qhov txo qhov cuam tshuam ntawm cov kab mob.
