China Supplier Pgr Plant Growth Regulator 4 Chlorophenoxyacetic Acid Sodium 4CPA 98%Tc

Kuchuluka kwa ntchito

P-chlorophenoxyacetic acid ndiwowongolera kukula kwa zomera za phenoxyl zomwe zimakhala ndi auxin. Amagwiritsidwa ntchito makamaka poletsa kugwa kwa maluwa ndi zipatso, kuletsa nyemba kuti zisagwe mizu, kulimbikitsa kukhazikika kwa zipatso, kupangitsa zipatso zopanda drupe, ndikulimbikitsa kukula.

Njira yogwiritsira ntchito

Molondola kulemera 1 gramu ya sodium chloropenoxate, kuika mu beaker (kapena galasi laling'ono), kuwonjezera pang'ono madzi otentha kapena 95% mowa, kusonkhezera mosalekeza ndi galasi ndodo mpaka kusungunuka, ndiyeno kuwonjezera madzi 500 ml, ndiko kuti, kukhala 2000 ml/kg wa mankhwala odana ndi kugwa katundu. Mukagwiritsidwa ntchito, ndikofunikira kuti muchepetse kuchuluka kwa yankho la stock ndi madzi pamlingo wofunikira pakupopera mbewu, kumiza, ndi zina.
(1) Pewani maluwa ndi zipatso kugwa:
① Isanakwane 9 koloko m'mawa, sungani maluwa achikazi a zukini ndi 30 mpaka 40 mg/kg ya mankhwala amadzimadzi.
②Ikani 30 mpaka 50 mg/kg ya mankhwala amadzimadzi m’mbale yaing’ono, ndi kuviika maluwa m’maŵa wa tsiku la biringanya la maluwa (kuviikani maluwawo m’mankhwala amadzimadzi, kenaka gwirani pamakhala mbali ya mbaleyo kuti madontho ochulukirapo alowe mu mbale).
③ Ndi 1 mpaka 5 mg/kg ya mankhwala amadzimadzi, ikani maluwa a nyemba, utsi kamodzi pa masiku khumi, utsi kawiri.
④ M'nyengo yophukira nyerere, ndi 4 mpaka 5 mg/kg ya mankhwala amadzimadzi, maluwa opopera, utsi kamodzi masiku 4 mpaka 5 aliwonse.
⑤Pamene 2/3 mwa maluwa atseguka pa inflorescence iliyonse ya phwetekere, thirirani maluwawo ndi 20 mpaka 30 mg/kg ya mankhwala amadzimadzi.

⑥ M'nyengo ya maluwa a mphesa, thirirani mankhwala amadzimadzi a 25 mpaka 30 mg/kg.
⑦ Pamene maluwa a nkhaka achikazi atseguka, tsitsani maluwa ndi 25 ~ 40 mg/kg ya mankhwala amadzimadzi.
⑧ Patangopita masiku atatu kuchokera ku maluwa okoma (wotentha) tsabola, tsitsani maluwa ndi 30 mpaka 50 mg/kg ya mankhwala amadzimadzi.
⑨ Nthawi yamaluwa ya mphonda yaikazi yoyera, ikani maluwa ndi 60 ~ 80 mg/kg ya mankhwala amadzimadzi.
(2) Kupititsa patsogolo storability: masiku 3 mpaka 10 isanafike kukolola Chinese kabichi, kusankha masana dzuwa, ndi 40 kuti 100 mg/kg ya madzi mankhwala, utsi kuchokera pansi mmwamba kuchokera m'munsi mwa kabichi Chinese, ndi masamba yonyowa ndi madzi mankhwala si kudontha, akhoza kuchepetsa nthawi yosungirako Chinese kabichi tsamba.

Zinthu zofunika kuziganizira

(1) Kusiya kugwiritsa ntchito masamba kutsala masiku atatu kukolola. Ndizotetezeka kugwiritsa ntchito kuposa madontho 2, 4. Gwiritsani ntchito mankhwala opopera mankhwala (monga mankhwala a mmero) kupopera maluwa ndikupewa kupopera mbewu pa mphukira ndi mphukira. Kuwongolera mosamalitsa mlingo, ndende ndi nthawi ya mankhwala kuti muteteze kuwonongeka kwa mankhwala.
(2) Pewani kugwiritsa ntchito mankhwala masiku otentha, otentha ndi mvula kuti musawononge mankhwala. Osagwiritsa ntchito mankhwalawa pamasamba osungidwa.

Mkhalidwe wosungira

Kusungirako 0-6 ° C; Tsekani ndi sitolo youma. Mpweya wabwino wa nyumba yosungiramo katundu ndi kuyanika kwa kutentha kochepa; Sungani ndi kunyamula mosiyana ndi zakudya zopangira.

Njira yokonzekera

Amapezeka ndi condensation wa phenol ndi chloroacetic acid ndi chlorination. 1. Condensation phenol wosungunuka umasakanizidwa ndi 15% sodium hydroxide solution, ndi chloroacetic acid amadzimadzi njira ndi neutralized ndi sodium carbonate. Awiriwo amasakanizidwa mumphika momwe amachitira ndi kutentha kwa reflux kwa 4h. Pambuyo pazimenezi, onjezerani hydrochloric acid ku pH ya 2-3, kuyambitsa ndi kuzizira, crystallize, fyuluta, kusamba m'madzi oundana, owuma, phenoxyacetic acid amapezeka. 2. Chlorination Sakanizani phenoxyacetic acid ndi glacial acetic acid kuti musungunuke, onjezerani mapiritsi a ayodini, ndi kuchotsa klorini pa 26-34 ℃. Pambuyo pa chlorine, kuika usiku, tsiku lotsatira mu madzi ozizira crystallization, fyuluta, kusamba ndi madzi mpaka ndale, youma anamaliza mankhwala.
