Lub teeb ua rau cov pob dub, hnyav ua rau tuag, thiab muaj qee cov organic impurities uas ua rau muaj kev phom sij rau tib neeg lub cev thiab ib puag ncig. Txhua yam nroj tsuag kev loj hlob regulator thiab tshuaj tua kab, nws purity muaj feem xyuam rau nws cov nyhuv, xws li high-purity sodium α-naphthalene acetate 5ppm (5μg / g) uas muaj cov nyhuv zoo, thaum zoo tib yam sodium α-naphthalene acetate yuav tsum tau mus txog 20ppm. (20μg / g) kom muaj txiaj ntsig.
(3) Zoo miscibility: siab purity α-naphthalene acetate sodium siv tau ua ke nrog ntau cov nroj tsuag kev loj hlob regulators, xws li: auxin, sodium nitrophenolate, rooting tshuaj, fungicides, chiv, thiab lwm yam .; Ordinary sodium alpha-naphthalene acetate feem ntau tsis siv ua ke.
Cov yam ntxwv ua haujlwm
High purity α-naphthalene acetate sodium yog ib qho kev loj hlob hormonecog kev loj hlob regulatornrog peb qhov teebmeem loj. Thawj yog los txhawb kev tsim cov hauv paus hniav thiab kev tsim cov hauv paus hniav, yog li nws tuaj yeem siv los txhawb cov noob cov hauv paus hniav thiab cov hauv paus hniav, tab sis ntau dhau ntawm cov ntsiab lus tseem tuaj yeem inhibit rooting. Qhov thib ob yog los txhawb kev nthuav dav ntawm cov txiv hmab txiv ntoo thiab cov hauv paus tuber, yog li nws tuaj yeem siv los ua qhov nthuav dav, thiab cov kev sim hauv teb tau ua pov thawj tias nws tuaj yeem ua rau muaj txiaj ntsig zoo thiab txhim kho qhov zoo ntawm liab peaches, txiv hmab txiv ntoo, txiv tsawb, dib, txiv lws suav. , peppers, eggplant, pears, txiv apples. Nyob rau tib lub sijhawm, nws txhawb kev nthuav dav sai ntawm cov hlwb, thiab kev loj hlob ntawm kev kho solanum ua rau muaj kev hloov pauv tsis zoo. Cov nyhuv nceb tshwj xeeb yog qhov tseem ceeb thiab tsis txo qhov zoo ntawm cov txiv hmab txiv ntoo. Qhov thib peb yog tiv thaiv kom tsis txhob poob paj thiab txiv hmab txiv ntoo, nrog rau kev tiv thaiv lub caij nplooj zeeg. Tsis tas li ntawd, nws kuj muaj lub luag haujlwm ntawm auxin dav dav, xws li txhawb kev loj hlob, txhawb chlorophyll synthesis, thiab txhawb nqa paj thiab paj paj sib txawv. Yog li ntawd, nws muaj cov txiaj ntsig ntawm kev txhawb nqa paj thiab txiv hmab txiv ntoo, txhawb nqa luxuriant ceg thiab nplooj, nce yield thiab txhim kho zoo, thiab txhim kho cov qoob loo tiv thaiv rau drought, txias thiab chaw nyob.
Txoj kev siv
Txoj kev siv high purity α-naphthalene acetate sodium
(1) Siv ib leeg
High purity sodium α-naphthalene acetate tuaj yeem npaj cais rau hauv dej, qab zib, hmoov thiab lwm yam tshuaj rau kev txhawb nqa kev loj hlob, kev cog qoob loo, kev txuag paj, khaws cov txiv hmab txiv ntoo thiab lwm yam. Kev siv ib zaug: 2 grams mus rau 30 kg dej. Kev ceeb toom tshwj xeeb: ntau ntau yog ua rau cov tshuaj puas tsuaj.
(2) Siv ua ke nrog sodium nitrophenolate
High purity α-naphthalene acetate sodium tuaj yeem ua ke nrog sodium nitrophenolate, kev loj hlob hormone, fungicide, chiv, thiab lwm yam. High purity sodium α-naphthalene acetate tuaj yeem ua ke nrog sodium nitrophenolate hauv Nyiv, Taiwan muaj ntau tshaj 20 xyoo keeb kwm, ob qho no Cheebtsam tuaj yeem sib koom ua ke, nthuav dav cov tshuaj spectrum efficiency, siv cov concentration txo, ob leeg muaj cov nyhuv ntawm sodium. nitrophenolate, tab sis kuj muaj cov nyhuv ntawm sodium α-naphthalene acetate, kom ua tiav ob zaug qhov tshwm sim nrog ib nrab ntawm kev siv zog.
Daim ntawv thov
Action mechanism
High purity sodium naphthalene acetate yog ib qho auxin cog regulator, uas nkag mus rau hauv cov nroj tsuag lub cev los ntawm nplooj, cov tawv nqaij thiab cov noob ntawm cov nroj tsuag, thiab yog thauj mus rau qhov chaw ntawm kev loj hlob (cov ntsiab lus loj hlob, cov tub ntxhais hluas lub cev, paj los yog txiv hmab txiv ntoo) nrog as-ham. ntws. Sodium naphthalene acetate obviously txhawb txoj kev loj hlob ntawm cov hauv paus hniav (hauv paus hmoov). Nws muaj peev xwm induce flowering, tiv thaiv poob txiv hmab txiv ntoo, tsim seedless txiv hmab txiv ntoo, txhawb thaum ntxov ripening thiab nce yield. Lub caij no, sodium naphthalene acetate kuj tuaj yeem txhim kho lub peev xwm ntawm drought-resistant, txias-resistant, kab mob-resistant, saline-alkali tsis kam thiab qhuav cua kub tsis kam ntawm cov nroj tsuag. High purity sodium naphthalene acetate tau sim hauv Nyiv, Taiwan thiab lwm qhov chaw, thiab nws cov txiaj ntsig siv tau zoo dua li cov sodium naphthalene acetate zoo tib yam.
