Mankhwala a Zaulimi Auxin Mahomoni Sodium Naphthoacetate Acid Naa-Na 98% Tc

Kapangidwe ka thupi ndi mankhwala

Chogulitsachi ndi granule yoyera, ufa kapena ufa wa kristalo; Chopanda fungo kapena fungo pang'ono, chotsekemera pang'ono komanso chamchere. Chogulitsachi chimasungunuka mosavuta m'madzi ndipo chimasungunuka pang'ono mu ethanol.

Yokhazikika mumlengalenga. Yankho lake ndi lokhazikika pa pH ya 7-10. Yosungunuka kwambiri m'madzi (53.0g/100ml, 25℃). Yosungunuka mu ethanol (1.4g/100ml). pH ya yankho lamadzi ndi 8. Mphamvu yoletsa kuwira ndi mphamvu yopha mabakiteriya ndi yofooka kuposa benzoic acid. Pa pH 3.5, yankho la 0.05% limaletsa kukula kwa yisiti, ndipo pa pH 6.5, kuchuluka kwa yankho loposa 2.5% kumafunika.

Ubwino ndi kuipa kwake

(1) Kusungunuka kwabwino kwambiri: α-naphthalene acetate sodium ndi yoyera kwambiri ndipo imakhala ndi madzi ndi mafuta, ndipo imatha kusungunuka kawiri, kotero imatha kupangidwa yokha kukhala madzi, ufa, kirimu, granule ndi mitundu ina ya mlingo, zomwe zimakhala zosavuta kugwiritsa ntchito ndipo zimakhala ndi zotsatira zabwino kwambiri. Chifukwa ndi molekyulu imodzi mu yankho, yomwazika mofanana, yosavuta kuyamwa ndi zomera, ndipo kuchuluka kwa 80% ya α-naphthalene acetate sodium kuyenera kusungunuka ndi ethanol, kugwiritsa ntchito ndikovuta kwambiri. Imapezeka m'magulu a mamolekyu mu ufa wa kirimu, kufalikira kwake ndi koipa, ndipo zotsatira zake sizabwino mwachibadwa.

(2) Kuyera kwambiri, kopanda zodetsa, zotsatira zoyipa zopanda poizoni: kuyera kwambiri α-naphthalene acetate sodium chiyero choposa 98%, chili ndi madzi ochepa, sichikhala ndi zodetsa zina zachilengedwe, kotero mukugwiritsa ntchito bwino kuchuluka kwa zinthu nthawi zambiri sikungayambitse kuwonongeka kwa mankhwala ku mbewu, ndipo α-naphthalene acetate sodium wamba chifukwa chokhala ndi 20% zodetsa zachilengedwe, Mu kuchuluka kogwiritsidwa ntchito bwino, kungayambitse kuwonongeka kwa mankhwala ku masamba ang'onoang'ono, mphukira ndi mbande za zomera. Kuwala kumayambitsa mawanga akuda, kumayambitsa imfa, ndipo pali zodetsa zachilengedwe zina zomwe zimayambitsa kuvulaza thupi la munthu ndi chilengedwe. Mtundu uliwonse wa chowongolera kukula kwa zomera ndi mankhwala ophera tizilombo, kuyera kwake kumakhudzana ndi zotsatira zake, monga sodium α-naphthalene acetate 5ppm(5μg/g) yomwe ili ndi zotsatira zabwino, pomwe sodium α-naphthalene acetate wamba iyenera kufika 20ppm(20μg/g) kuti ikhale ndi zotsatira.

(3) Kusakaniza bwino: sodium ya α-naphthalene acetate yoyera kwambiri ingagwiritsidwe ntchito limodzi ndi owongolera kukula kwa zomera ambiri, monga: auxin, sodium nitrophenolate, zinthu zoyambira mizu, fungicides, feteleza, ndi zina zotero; sodium alpha-naphthalene acetate wamba nthawi zambiri sigwiritsidwa ntchito limodzi.

Makhalidwe ogwira ntchito

α-naphthalene acetate sodium yoyera kwambiri ndi hormone yokulitsachowongolera kukula kwa zomerandi zotsatira zitatu zazikulu. Choyamba ndikulimbikitsa kupangika kwa mizu yoyambira ndi kupangika kwa mizu, kotero ingagwiritsidwe ntchito kukulitsa mizu ya mbewu ndi mizu, koma kuyika kwambiri kungalepheretsenso mizu. Chachiwiri ndikulimbikitsa kukulira kwa zipatso ndi mizu ya tuber, kotero ingagwiritsidwe ntchito ngati chinthu chokulitsa, ndipo mayeso akumunda atsimikizira kuti imatha kukulitsa kwambiri zokolola ndikukweza mtundu wa mapichesi a monkey, mphesa, chivwende, nkhaka, tomato, tsabola, biringanya, mapeyala, maapulo. Nthawi yomweyo, imalimbikitsa kukula mwachangu kwa maselo, ndipo kuchuluka kwa kukula kwa solanum yochiritsidwa kumabweretsa kusintha kodabwitsa. Zotsatira za bowa ndizofunikira kwambiri ndipo sizichepetsa mtundu wa zipatso. Chachitatu ndikuletsa maluwa ndi zipatso kugwa, ndi ntchito yoletsa kugwa. Kuphatikiza apo, ilinso ndi ntchito ya auxin wamba, monga kulimbikitsa kukula, kulimbikitsa kupanga chlorophyll, ndikulimbikitsa kusiyana kwa mphukira ndi maluwa. Chifukwa chake, ili ndi mphamvu yolimbikitsa maluwa ndi zipatso, kulimbikitsa nthambi ndi masamba obiriwira, kukulitsa zokolola ndikuwongolera mtundu, ndikukweza kukana kwa mbewu ku chilala, kuzizira ndi malo ogona.

Njira yogwiritsira ntchito

Njira yogwiritsira ntchito α-naphthalene acetate sodium yoyera kwambiri

(1) Gwiritsani ntchito yokha

Sodium α-naphthalene acetate yoyera kwambiri ikhoza kukonzedwa padera m'madzi, kirimu, ufa ndi mitundu ina ya mlingo kuti ikule bwino, mizu, kusunga maluwa, kusunga zipatso ndi zina zotero. Mlingo wogwiritsidwa ntchito kamodzi: 2 magalamu mpaka 30 makilogalamu a madzi. Chikumbutso chapadera: kuchuluka kwambiri kumatha kuwonongeka ndi mankhwala.

(2) Amagwiritsidwa ntchito limodzi ndi sodium nitrophenolate

α-naphthalene acetate sodium yoyera kwambiri imatha kuphatikizidwa ndi sodium nitrophenolate, kukula kwa mahomoni, fungicide, feteleza, ndi zina zotero. α-naphthalene acetate yoyera kwambiri imatha kuphatikizidwa ndi sodium nitrophenolate ku Japan, Taiwan ili ndi mbiri ya zaka zoposa 20, zigawo ziwirizi zimatha kugwirizana, kukulitsa mphamvu ya mankhwala, kugwiritsa ntchito kuchepetsa kuchuluka, zonse zimakhala ndi mphamvu ya sodium nitrophenolate, komanso zimakhala ndi mphamvu ya sodium α-naphthalene acetate, kuti zikwaniritse zotsatira kawiri ndi theka la khama.

Kugwiritsa ntchito

Njira yochitira zinthu

Sodium naphthalene acetate yoyera bwino ndi mankhwala oletsa zomera, omwe amalowa m'thupi la chomera kudzera m'masamba, khungu lofewa ndi mbewu za zomera, ndipo amatengedwa kupita kumadera omwe kukula kwake kuli kolimba (malo okulira, ziwalo zazing'ono, maluwa kapena zipatso) ndi michere. Sodium naphthalene acetate mwachionekere inalimbikitsa kukula kwa nsonga ya muzu (ufa wa muzu). Ikhoza kuyambitsa maluwa, kuletsa kugwa kwa zipatso, kupanga zipatso zopanda mbewu, kulimbikitsa kucha msanga ndikuwonjezera zokolola. Pakadali pano, sodium naphthalene acetate ingathandizenso kupirira chilala, kukana kuzizira, kukana matenda, kukana saline-alkali komanso kukana mpweya wouma wotentha wa zomera. Sodium naphthalene acetate yoyera kwambiri inayesedwa ku Japan, Taiwan ndi malo ena, ndipo kugwiritsa ntchito kwake kunali bwino kwambiri kuposa sodium naphthalene acetate wamba.

Njira yodziwira

(1) Pambuyo potenga pafupifupi 0.5g ya mankhwalawa ndikuwonjezera 10ml ya madzi kuti asungunuke, yankholo linawonetsa kusiyana pakati pa mchere wa sodium ndi benzoate.

(2) Mtundu wa infrared light absorption wa chinthuchi uyenera kugwirizana ndi mtundu wa control spectrum.

Kuyang'ana chizindikiro

Ph tengani 1.0g ya mankhwalawa, onjezerani 20ml ya madzi kuti asungunuke, onjezerani madontho awiri a yankho la phenolphthalein indicator; Ngati likuwonetsa kufiira kopepuka, onjezerani yankho la sulfuric acid titration (0.05mol/L)0.25ml, kufiira kopepuka kuyenera kuzimiririka; Ngati palibe mtundu, onjezerani sodium hydroxide titrant (0.1mol/L)0.25ml, liyenera kuwonetsa kufiira kopepuka.
