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

Kukula kwa ntchito

P-chlorophenoxyacetic acid ndi mankhwala owongolera kukula kwa zomera za phenoxyl zomwe zimakhala ndi mphamvu ya auxin. Amagwiritsidwa ntchito makamaka poletsa kugwa kwa maluwa ndi zipatso, kuletsa nyemba kuti zisamere mizu, kulimbikitsa kukhazikika kwa zipatso, kuyambitsa zipatso zopanda ma drupe, komanso kulimbikitsa kukula kwa zipatso.

Njira yogwiritsira ntchito

Yesani bwino 1 g ya sodium chloropenoxate, ikani mu beaker (kapena galasi laling'ono), onjezerani madzi otentha pang'ono kapena 95% alcohol, sakanizani mosalekeza ndi ndodo yagalasi mpaka itasungunuka kwathunthu, kenako onjezerani madzi ku 500 ml, kutanthauza kuti, ikhale 2000 ml/kg ya yankho la anti-fall stock. Mukagwiritsa ntchito, ndibwino kusakaniza kuchuluka kwa yankho la sodium chloropenoxate ndi madzi mpaka kuchuluka kofunikira popopera, kuviika, ndi zina zotero.
(1) Pewani kugwa kwa maluwa ndi zipatso:
① Musanayambe komanso mutatha 9 koloko m'mawa, ikani maluwa achikazi a zukini ndi 30 mpaka 40 mg/kg ya mankhwala amadzimadzi.
②Ikani 30 mpaka 50 mg/kg ya mankhwala amadzimadzi mu mbale yaying'ono, ndipo ziviikani maluwa m'mawa wa tsiku lomwe biringanya limatuluka (viikani maluwawo mu mankhwala amadzimadzi, kenako gwirani maluwa omwe ali m'mbali mwa mbale kuti madontho ochulukirapo alowe m'mbale).
③ Ndi 1 mpaka 5 mg/kg ya mankhwala amadzimadzi, thirani nyemba zomwe zayamba kutulutsa maluwa, thirani kamodzi pa masiku 10 aliwonse, thirani kawiri.
④ Mu nthawi yophukira ya maluwa a nyemba za ng'ombe, perekani mankhwala amadzimadzi a 4 mpaka 5 mg/kg, thirani maluwa, thirani kamodzi pa masiku 4 mpaka 5 aliwonse.
⑤Pamene 2/3 ya maluwa yatsegulidwa pa inflorescence iliyonse ya phwetekere, thirani maluwawo ndi 20 mpaka 30 mg/kg ya mankhwala amadzimadzi.

⑥ Mu nthawi ya maluwa a mphesa, thirani 25 mpaka 30 mg/kg ya mankhwala amadzimadzi.
⑦ Maluwa achikazi a nkhaka akatsegulidwa, thirani maluwa ndi 25 ~ 40 mg/kg ya mankhwala amadzimadzi.
⑧ Patatha masiku atatu kuchokera pamene maluwa a tsabola wotsekemera (wotentha), thirani maluwawo ndi 30 mpaka 50 mg/kg ya mankhwala amadzimadzi.
⑨ Mu nthawi ya maluwa a chigwa chachikazi choyera, thirani maluwawo ndi 60 ~ 80 mg/kg ya mankhwala amadzimadzi.
(2) Kusunga bwino: Masiku atatu mpaka 10 kabichi waku China asanakololedwe, sankhani masana a dzuwa, ndi 40 mpaka 100 mg/kg ya mankhwala amadzimadzi, thirani kuchokera pansi kupita mmwamba kuchokera pansi pa kabichi waku China, ndi masamba onyowa ndipo mankhwala amadzimadziwo sakudontha, kungachepetse nthawi yosungira tsamba la kabichi waku China.

Nkhani zofunika kuziganizira

(1) Siyani kugwiritsa ntchito ndiwo zamasamba masiku atatu musanayambe kukolola. Ndikotetezeka kugwiritsa ntchito kuposa madontho awiri, anayi. Gwiritsani ntchito chopopera chaching'ono (monga chopopera pakhosi) kuti mupopere maluwa ndikupewa kupopera pa mphukira ndi mphukira. Yang'anirani mosamala mlingo, kuchuluka kwa mankhwalawa, ndi nthawi yomwe mankhwalawo akugwiritsidwa ntchito kuti mupewe kuwonongeka kwa mankhwala.
(2) Pewani kugwiritsa ntchito mankhwala masiku otentha, otentha komanso amvula kuti mupewe kuwonongeka kwa mankhwala. Musagwiritse ntchito mankhwalawa pa ndiwo zamasamba zosungidwa.

Mkhalidwe wosungira

Malo osungiramo zinthu 0-6°C; Tsekani ndi kuumitsa sitolo. Mpweya wolowera m'nyumba yosungiramo zinthu komanso kuumitsa kutentha kochepa; Sungani ndikunyamula padera kuzinthu zopangira chakudya.

Njira yokonzekera

Zimapezedwa mwa kusakaniza phenol ndi chloroacetic acid ndi chlorination. 1. Kusakaniza phenol yosungunuka imasakanizidwa ndi 15% sodium hydroxide solution, ndipo chloroacetic acid aqueous solution imachepetsedwa ndi sodium carbonate. Ziwirizi zimasakanizidwa mu mphika wa reaction ndikutenthedwa kuti ziume kwa maola 4. Pambuyo pa reaction, onjezerani hydrochloric acid ku pH ya 2-3, sakanizani ndikuziziritsa, crystallize, filter, sambani m'madzi oundana, owuma, phenoxyacetic acid imapezedwa. 2. Chlorination Sakanizani phenoxyacetic acid ndi glacial acetic acid kuti isungunuke, onjezerani mapiritsi a ayodini, ndikuchotsa chlorine pa 26-34℃. Pambuyo pa chlorine, ikani usiku wonse, tsiku lotsatira mu crystallization ya madzi ozizira, filter, sambani ndi madzi mpaka zinthu zouma, zouma.
