Kiimikada Beeraha Auxin Hormoonnada Sodium Naphthoacetate Acid Naa-Na 98% Tc

sifooyinka jirka iyo kiimikaad

Alaabtani waa granule cad, budada ama budada crystalline;Aan ur lahayn ama waxyar ur, waxoogaa macaan oo milix leh.Alaabtani si fudud bay ugu milmi kartaa biyaha oo wax yar bay ku milmi kartaa ethanol.

Hawo deggan.Xalku wuxuu ku degan yahay pH 7-10.Aad ugu milmay biyaha (53.0g/100ml,25℃).Ku milmay ethanol (1.4g/100ml).Qiimaha pH ee xalka aqueous waa 8. Awoodda ka hortagga halsano iyo awoodda bakteeriyada ayaa ka daciifsan benzoic acid.Marka pH 3.5, 0.05% xal si buuxda uga hortagtaa koritaanka khamiirka, iyo pH 6.5, diiradda in ka badan 2.5% xal ayaa loo baahan yahay.

Faa'iidada iyo khasaaraha

(1) Solubility heer sare ah: nadiif sare α-naphthalene acetate sodium waxay leedahay biyo iyo saliid laba-milmi, sidaas darteed si madax-bannaan ayaa loo samayn karaa biyo, budada, kareemka, granule iyo foomamka qiyaasta kale, taas oo aad u habboon in la isticmaalo oo leh mid aad u fiican. saamayn wanaagsan.Sababtoo ah waa hal molecule ee xalka, oo si siman u kala firdhiyey, si sahlan loo nuugo dhirta, iyo nuxurka caadiga ah ee 80% α-naphthalene acetate sodium wuxuu u baahan yahay in lagu milmo ethanol, isticmaalka waa mid aad u dhib badan.Waxay ku jirtaa xaaladda kooxaha molecular ee budada kareemka, kala firidhsanaanta ayaa liidata, saameyntuna si dabiici ah uma fiicna.

(2) Nadiif sare, wax wasakh ah oo aan lahayn, waxyeellooyin aan sun ahayn: saafiga sare ee α-naphthalene acetate sodium nadiif ah oo ka badan 98%, waxaa ku jira qadar yar oo biyo ah, kuma jiraan wasakh kale oo dabiici ah, sidaas darteed isticmaalka waxtarka leh ee feejignaanta kala duwan guud ahaan ma keeni doono waxyeelo daroogada ee dalagyada, iyo caadiga ah α-naphthalene acetate sodium ay sabab u tahay ka kooban 20% wasakh organic, In kala duwan ee isticmaalka waxtarka leh fiirsashada, waxay keeni doontaa waxyeelo daroogada caleemaha yar yar, burooyinkeeda iyo geedo dhirta.Iftiinku wuxuu keenaa dhibco madow, culculus wuxuu keenaa dhimasho, waxaana jira waxyaabo wasakh ah oo dabiici ah oo waxyeelo u geysta jidhka bini'aadamka iyo deegaanka.Nooc kasta oo ka mid ah xakamaynta koritaanka dhirta iyo sunta cayayaanka, nadiifnimadeeda waxay la xiriirtaa saameynteeda, sida saafiga sare ee sodium α-naphthalene acetate 5ppm (5μg / g) taas oo leh saameyn wanaagsan, halka sodium α-naphthalene acetate ee caadiga ah ay u baahan tahay inay gaarto 20ppm (20μg/g) si ay saameyn ugu yeelato.

(3) Maqnaanshaha wanaagsan: nadiifnimada sare ee α-naphthalene acetate sodium waxaa loo isticmaali karaa iyadoo lagu darayo nidaamiyayaal badan oo koritaanka dhirta, sida: auxin, sodium nitrophenolate, walxaha xididka, fungicides, Bacriminta, iwm.;Alfa-naphthalene acetate sodium-ka caadiga ah guud ahaan looma isticmaalo isku darka.

Sifooyin shaqo

Nadiifinta sare α-naphthalene acetate sodium waa hormoonka koritaankanidaamiyaha koritaanka dhirtaoo leh saddex saameyn oo waaweyn.Midda koowaad waa in kor loo qaado samaynta xididdada advental iyo samaynta xididka, sidaa darteed waxaa loo isticmaali karaa in kor loogu qaado xididdada abuurka iyo xididdada, laakiin feejignaan badan ayaa sidoo kale joojin karta xididada.Midda labaad waa in kor loo qaado balaadhinta khudradda iyo tuberka xididka, sidaas awgeed waxaa loo isticmaali karaa in ay noqoto arrin balaadhin ah, waxaana tijaabooyin lagu sameeyay goobta lagu caddeeyey in ay si weyn u kordhin karaan wax-soo-saarka iyo wanaajinta tayada fersken daayeer, canabka, qaraha, qajaarka, yaanyada. , basbaaska, eggplant, isteroberi, tufaax.Isla mar ahaantaana, waxay kor u qaadaysaa balaadhinta degdega ah ee unugyada, iyo heerka korriinka solanum ee la daweeyay waxay soo saartaa isbeddello mucjiso ah.Saamaynta likaha ayaa si gaar ah muhiim u ah mana yarayso tayada midhaha.Midda saddexaad waa in laga hortago ubaxyada iyo miraha soo dhacaya, oo leh shaqeyn ka hortagga dayrta.Intaa waxaa dheer, waxay sidoo kale leedahay hawlaha auxin guud, sida kor u qaadida korriinka, kor u qaadida isku-dhafka chlorophyll, iyo kor u qaadida kala duwanaanshaha bud iyo ubaxa.Sidaa darteed, waxay leedahay saamaynta kor u qaadida ubaxa iyo miraha, kor u qaadida laamaha iyo caleemaha raaxada, kordhinta wax soo saarka iyo hagaajinta tayada, iyo hagaajinta iska caabinta dalagyada abaarta, qabowga iyo hoyga.

Habka isticmaalka

Habka loo isticmaalo nadiifnimada sare ee α-naphthalene acetate sodium

(1) Isticmaal kaligaa

Nadiifinta sare ee sodium α-naphthalene acetate waxaa si gooni ah loogu diyaarin karaa biyo, kareem, budada iyo qaababka kale ee qiyaasta si kor loogu qaado koritaanka, xididdada, ilaalinta ubaxa, ilaalinta miraha iyo wixii la mid ah.Qiyaasta hal isticmaalka: 2 garaam ilaa 30 kiiloogaraam oo biyo ah.Xusuusin gaar ah: tiro badan ayaa u nugul waxyeellada daroogada.

(2) Waxaa loo adeegsaday iyadoo lagu daray nitrophenolate sodium

Nadiifinta sare ee α-naphthalene acetate sodium waxaa lagu dari karaa sodium nitrophenolate, hormoonka koritaanka, fungicides, bacriminta, iwm. Qaybaha ayaa si wadajir ah u wada shaqeyn kara, ballaarinta waxtarka daawada daroogada, isticmaalka hoos u dhigista xoojinta, labaduba waxay leeyihiin saameynta sodium nitrophenolate, laakiin sidoo kale waxay leeyihiin saameynta sodium α-naphthalene acetate, si loo gaaro natiijada laba jeer kala badh dadaalka.

Codsiga

Farsamaynta waxqabadka

Naaftada sodium naphthalene acetate oo nadiif ah oo nadiif ah waa nidaamiye warshad auxin, kaas oo ka soo gala jidhka geedka caleemaha, maqaarka jilicsan iyo miraha dhirta, waxaana loo qaadaa qaybaha koritaanka xooggan (dhibcaha koritaanka, xubnaha dhalinyarada, ubaxa ama miraha) oo leh nafaqo. socodka.Sodium naphthalene acetate ayaa si cad u kor u qaaday horumarinta cirifka xididka (budada xididka).Waxay dhalin kartaa ubax, waxay ka hortagtaa midho dhaca, samayn kartaa midho aan abuur lahayn, waxay kor u qaadaa bislaanshaha hore waxayna kordhisaa dhalidda.Dhanka kale, sodium naphthalene acetate waxay sidoo kale kor u qaadi kartaa awoodda caabbinta abaarta, caabbinta qabow, caabbinta cudurada, caabbinta milixda-alkali iyo iska caabbinta hawada kulul ee qalalan ee dhirta.Naphthalene acetate oo nadiif ah oo sarreeya ayaa lagu tijaabiyay Japan, Taiwan iyo meelo kale, saameynteeduna aad ayey uga wanaagsan tahay tan caadiga ah ee sodium naphthalene acetate.
