Nyob rau hauv txoj kev loj hlob ntawm kev ua liaj ua teb niaj hnub no, cov nroj tsuag kev loj hlob regulators tau dhau los ua cov tshuaj tseem ceeb rau cov neeg cog qoob loo, ua lub luag haujlwm hauv inhibiting lossis txhawb kev loj hlob thiab kev loj hlob ntawm cov nroj tsuag zoo ib yam lossis sib txawv. Niaj hnub no, peb tsom mus rau sodium naphthalenacetate (NAA). Ntau tus neeg cog qoob loo xav nkag siab NAA thiab xav paub yog tias nws yog qhov dav -spectrum regulator. Kab lus no yuav piav qhia seb nws yog dab tsi, seb nws puas ua haujlwm ntawm koj cov nroj tsuag, thiab cov tswv yim siv.
Dab tsi yog sodium naphthalenacetate?
Sodium naphthalenacetate (NAA) zoo nkaus li dawb granules, hmoov, los yog crystalline hmoov; nws tsis muaj ntxhiab los yog muaj ntxhiab tsw me ntsis, nrog me ntsis qab zib thiab qab ntsev. Nws ruaj khov nyob rau hauv chav tsev kub thiab nyob rau hauv kev daws ntawm pH 7-10, thiab yog heev soluble nyob rau hauv dej. Nws cov pH soluble hauv ethanol yog 8. Sodium NAA yog sodium ntsev ntawm lub hauv paus muaj zog thiab tsis muaj zog acid naphthalenacetic acid (NAA). Thaum hydrolysis, nws tsim NAA. Cov nroj tsuag siv ions, yog li qhov muaj NAA ions txaus rau nws txoj haujlwm.
Puas yog sodium naphthalenacetate yog dav -spectrum cog kev loj hlob regulator?
Ua ntej, cia peb qhia seb qhov dav -spectrum cog kev loj hlob regulator yog. Nws yog hais txog kev loj hlob ntawm cov nroj tsuag uas muaj feem xyuam rau ntau yam qoob loo thiab siv nyob rau hauv ntau theem kev loj hlob, tsis yog tsom rau ib qho qoob loo lossis ib qho txheej txheem physiological nkaus xwb.
Sodium naphthaleneacetate (NAA) yog hom no: siab -purity NAA nkag mus rau cov nroj tsuag los ntawm nplooj, cov tawv nqaij tawv nqaij, thiab cov noob, thiab thauj nrog cov khoom noj khoom haus txaus mus rau qhov chaw loj hlob (cov ntsiab lus loj hlob, cov kab mob me, paj, lossis txiv hmab txiv ntoo), txhawb nqa cell faib thiab nthuav dav 1}cov txiv hmab txiv ntoo, cov neeg sawv cev ntawm cov txiv hmab txiv ntoo thiab cov txiv hmab txiv ntoo nthuav dav. thiab txhawb kev loj hlob hauv paus ntsiab lus, inducing tsim ntawm adventitious keeb kwm (rooting hmoov). Nws muaj lub luag haujlwm ntawm kev tswj kev loj hlob, txhawb cov cag thiab sprouting, inducing flowering, tiv thaiv paj thiab txiv hmab txiv ntoo poob, tsim seedless txiv hmab txiv ntoo, txhawb kev loj hlob thaum ntxov, thiab nce yield. Ib txhij, NAA tseem tuaj yeem txhim kho cov nroj tsuag tiv taus dej qhuav, txias, kab mob, salinity, thiab kub, cua qhuav.
Nws yog ib qho dav -spectrum, muaj txiaj ntsig zoo, thiab qis- tshuaj lom cog kev loj hlob regulator.
Daim ntawv teev cov qoob loo
Raws li ib tug dav -spectrum cog kev loj hlob regulator, sodium naphthaleneacetate muaj ntau hom siv tau, npog cov txiv hmab txiv ntoo, melons, solanaceous zaub, thiab edible fungi: txiv lws suav, kiwis, txiv quav ntswv nyoos, watermelons, dib, peppers, eggplants, pears, apples, thiab cov nceb nyob rau hauv tag nrho cov.
Hauv Ecuador, sodium naphthalenacetate (NAA) tau siv dav hauv kev cog qoob loo kiwifruit. Ntau lub kiwifruit orchards muaj siv NAA los tiv thaiv paj thiab txiv hmab txiv ntoo, txo cov txiv hmab txiv ntoo poob, thiab nce kiwifruit tawm los thiab cov txiv hmab txiv ntoo lag luam. Nws yog ib qho ntawm feem ntau siv cog kev loj hlob regulators nyob rau hauv Ecuadorian kiwifruit ua liaj ua teb. Tsis tas li ntawd, cov neeg cog txiv lws suav thiab kua txob hauv ntau lub tebchaws Esxias sab hnub tuaj tau siv NAA ntev los daws qhov teeb meem ntawm cov paj poob hauv cov zaub.
Cov lus qhia rau kev siv sodium naphthalenacetate
Txhawm rau kom ntseeg tau tias sodium naphthaleneacetate (NAA) ua tiav cov txiaj ntsig ruaj khov, qhov tseem ceeb tsis yog nyob rau hauv qhov muag tsis pom kev siv cov tshuaj, tab sis hauv kev tswj lub sijhawm, concentration, ib puag ncig, thiab kev tsim ntawm daim ntawv thov. Hauv qab no yog cov txheej txheem tseem ceeb siv los ntawm cov neeg cog qoob loo hauv kev xyaum:
• Tswj cov ntawv thov concentration; yuam kev nyob rau sab ntawm dilution ntau dua li concentration.
High concentrations tau yooj yim ua rau phytotoxicity, ua rau yellowing nplooj thiab deformed cov txiv hmab txiv ntoo hluas. Thaum siv, nws yog ib qho tsim nyog yuav tau dilute nrog dej raws li kev pom zoo noj raws li cov qoob loo ntau yam thiab theem kev loj hlob.
• Txhim kho lub sijhawm tsim nyog rau kev siv tshuaj tua kab
Siv tshuaj tua kab thaum sawv ntxov lossis yav tav su lig thaum qhov kub ntawm 20 txog 28℃thiab tsis muaj cua. Tsis txhob siv tshuaj tua kab thaum nruab hnub tshav kub thiab lub hnub ci muaj zog, vim tias cov evaporation ceev yuav tsis tsuas yog txo qhov nqus tau zoo tab sis kuj yooj yim ua rau phytotoxicity. Yog hais tias nws los nag hauv 4 teev tom qab txau, rov- tsuag tom qab los nag.
·Khaws kom raug
Feem ntau, nws tuaj yeem raug kaw thiab khaws cia rau hauv qhov chaw txias, qhuav, thiab tsaus ntuj, tsis txhob ya raws, kub thiab tshav ntuj; cov tshuaj npaj yuav tsum tsis txhob khaws cia ntev, thiab yuav tsum tau npaj thiab siv tam sim ntawd.
