(2) Kev huv siab, tsis muaj impurities, tsis muaj tshuaj lom rau sab: kev huv siab α-naphthalene acetate sodium purity ntau dua 98%, muaj dej me me, tsis muaj lwm yam organic impurities, yog li thaum siv cov concentration zoo feem ntau yuav tsis ua rau cov tshuaj puas tsuaj rau cov qoob loo, thiab α-naphthalene acetate sodium ib txwm vim muaj 20% organic impurities, Hauv cov concentration siv zoo, nws yuav ua rau cov tshuaj puas tsuaj rau cov nplooj hluas, cov paj thiab cov noob ntawm cov nroj tsuag. Lub teeb ua rau cov pob dub, hnyav ua rau tuag, thiab muaj qee cov organic impurities uas ua rau tib neeg lub cev thiab ib puag ncig puas tsuaj. Txhua yam tshuaj tswj kev loj hlob ntawm cov nroj tsuag thiab tshuaj tua kab, nws qhov kev huv yog cuam tshuam nrog nws cov nyhuv, xws li sodium α-naphthalene acetate 5ppm (5μg / g) uas muaj cov nyhuv zoo, thaum sodium α-naphthalene acetate ib txwm yuav tsum ncav cuag 20ppm (20μg / g) kom muaj cov nyhuv.
(3) Kev sib xyaw zoo: cov khoom siv α-naphthalene acetate sodium siab tuaj yeem siv ua ke nrog ntau cov tshuaj tswj kev loj hlob ntawm cov nroj tsuag, xws li: auxin, sodium nitrophenolate, cov tshuaj cag, fungicides, chiv, thiab lwm yam; sodium alpha-naphthalene acetate feem ntau tsis siv ua ke.
Cov yam ntxwv ua haujlwm
High purity α-naphthalene acetate sodium yog ib qho hormone loj hlobkev tswj kev loj hlob ntawm cov nroj tsuagnrog peb qhov cuam tshuam loj. Thawj qhov yog txhawb kev tsim cov hauv paus advental thiab cov hauv paus tsim, yog li nws tuaj yeem siv los txhawb cov hauv paus noob thiab rooting, tab sis kev concentration ntau dhau kuj tuaj yeem tiv thaiv rooting. Qhov thib ob yog txhawb kev nthuav dav ntawm cov txiv hmab txiv ntoo thiab cov hauv paus tuber, yog li nws tuaj yeem siv ua qhov nthuav dav, thiab kev sim hauv teb tau ua pov thawj tias nws tuaj yeem ua rau cov qoob loo ntau ntxiv thiab txhim kho qhov zoo ntawm cov txiv duaj liab, txiv hmab, txiv tsawb, dib, txiv lws suav, kua txob, eggplant, pears, txiv apples. Tib lub sijhawm, nws txhawb kev nthuav dav sai ntawm cov hlwb, thiab qhov kev loj hlob ntawm cov tshuaj solanum kho tsim cov kev hloov pauv zoo kawg nkaus. Cov nyhuv nceb yog qhov tseem ceeb tshwj xeeb thiab tsis txo qhov zoo ntawm cov txiv hmab txiv ntoo. Qhov thib peb yog los tiv thaiv cov paj poob thiab txiv hmab txiv ntoo, nrog rau kev ua haujlwm tiv thaiv kev poob. Tsis tas li ntawd, nws kuj muaj cov haujlwm ntawm cov auxin dav dav, xws li txhawb kev loj hlob, txhawb kev tsim chlorophyll, thiab txhawb kev sib txawv ntawm cov paj thiab paj. Yog li ntawd, nws muaj cov nyhuv ntawm kev txhawb nqa paj thiab txiv hmab txiv ntoo, txhawb nqa cov ceg thiab nplooj zoo nkauj, nce cov qoob loo thiab txhim kho qhov zoo, thiab txhim kho kev tiv thaiv ntawm cov qoob loo rau kev qhuav, txias thiab chaw nyob.
