1. Siv cov tshuaj kom tsim nyog; tsis txhob arbitrarily nce qhov ntau npaum. Cov nroj tsuag kev loj hlob regulators yog cov khoom uas zoo sib xws physiological thiab biological teebmeem rau cog cov tshuaj hormones thiab yuav tsum tsis txhob siv ntau dhau. Feem ntau, tsuas yog ob peb grams lossis milliliters ib evkawj tsuas yog xav tau. Qee tus neeg ua liaj ua teb ntshai tias qhov ntau npaum li cas me me yuav tsis ua haujlwm thiab ua rau qhov ntau npaum li cas lossis qhov concentration. Ua li no yuav tsis tsuas yog ua tsis tau zoo los txhawb kev loj hlob ntawm cov nroj tsuag, tab sis kuj yuav inhibit nws, thiab nyob rau hauv cov xwm txheej hnyav, tej zaum yuav ua rau cov nplooj deformities, ziab thiab shedding, thiab tag nrho cov nroj tsuag tuag.
2. Tsis txhob sib xyaw ua ke. Ntau tus neeg ua liaj ua teb, txhawm rau txuag lub sijhawm, feem ntau sib xyaw cog kev loj hlob regulators indiscriminately nrog chiv, tshuaj tua kab, fungicides, thiab lwm yam. Txawm hais tias cov nroj tsuag loj hlob regulators yuav tsum tau tov nrog chiv, tshuaj tua kab, thiab lwm yam, yuav tsum tau txiav txim siab tom qab ua tib zoo nyeem cov lus qhia rau kev siv thiab ua thwmsim. Txwv tsis pub, tsis tsuas yog lawv yuav tsis ua tiav cov txiaj ntsig ntawm kev txhawb nqa kev loj hlob, tiv thaiv paj thiab txiv hmab txiv ntoo, lossis ntxiv cov chiv, tab sis kev sib xyaw tsis raug kuj tuaj yeem ua rau phytotoxicity. Piv txwv li: Ethephon tov feem ntau yog acidic thiab tsis tuaj yeem tov nrog cov tshuaj alkaline; amino acid esters decompose yooj yim hauv alkali thiab tsis tuaj yeem tov nrog alkaline tshuaj tua kab lossis chiv.
3. Kev thov kom raug yog qhov tseem ceeb. Qee cov neeg ua liaj ua teb feem ntau tsis ua tib zoo nyeem cov lus qhia ua ntej siv cov tswj kev loj hlob ntawm cov nroj tsuag thiab ncaj qha dilute lawv nrog dej. Nws yog ib qho tseem ceeb kom ua tib zoo xyuas seb puas muaj qhov ncaj qha dilution puas tau, vim qee cov nroj tsuag kev loj hlob tsis tuaj yeem yaj ncaj qha rau hauv dej. Yog tias cov tshuaj tsis tau npaj ua ntej kom ua tiav qhov xav tau concentration, tus neeg sawv cev yuav nyuaj rau sib tov sib npaug, cuam tshuam rau nws cov txiaj ntsig. Yog li ntawd, nws yog ib qho tseem ceeb kom ua raws li cov lus qhia dilution nruj me ntsis.
4. Cov tswj kev loj hlob tsis tuaj yeem hloov cov chiv. Kev loj hlob regulators tsis cog cov as-ham; lawv tsuas tswj kev loj hlob thiab hloov tsis tau chiv. Kev siv ntau ntau ntawm cov nroj tsuag kev loj hlob regulators thaum dej thiab chiv tsis txaus yuav ua rau muaj teeb meem. Yog li ntawd, thaum pom kev loj hlob tsis zoo, fertilization thiab watering yuav tsum tau ntxiv dag zog ua ntej. Tsuas yog ntawm lub hauv paus no tuaj yeem siv cov regulators loj hlob zoo.
5. Cov kws tswj kev loj hlob ntawm cov nroj tsuag tau muab cais ua cov tshuaj tua kab. Cov khoom ntim yuav tsum tso saib "peb daim ntawv pov thawj rau cov tshuaj tua kab," uas qhia los ntawm daim ntawv daj.
6. Ua raws nraim li cov lus qhia rau kev siv, thiab siv cov kev tiv thaiv tsim nyog kom tsis txhob muaj kev phom sij rau tib neeg, tsiaj txhu, lossis dej haus.
