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

Chikamu chekushandisa

P-chlorophenoxyacetic acid ndeyekukura regulator ye phenoxyl zvirimwa zvine auxin chiitiko.Inonyanya kushandiswa kudzivirira maruva nemichero inodonha, inhibit legumes kubva kumidzi, kukurudzira kugadzirisa michero, kukurudzira michero isina drupe, uye kukurudzira kukura.

Kushandisa nzira

Nyatsoyera 1 gram ye sodium chloropenoxate, isa mubeaker (kana girazi diki), wedzera mvura shoma inopisa kana 95% doro, kurunga uchienderera negirazi tsvimbo kusvika yanyungudika, wobva wawedzera mvura ku500. ml, kureva kuti, kuva 2000 ml/kg ye anti-fall stock solution.Kana yashandiswa, zvinokurudzirwa kudzikisa imwe huwandu hwemhinduro yemasheya nemvura kune inodiwa yekumisikidza yekupfapfaidza, kunyura, nezvimwe.
(1) Dzivirira kudonha kwemaruva nemichero:
① Pamberi uye mushure me9 am, nyura yakavhurika maruva echikadzi ne30 kusvika 40 mg/kg yemushonga wemvura.
②Isa 30 kusvika 50 mg/kg yemushonga wemvura mundiro diki, wonyika maruva mangwanani ezuva rekutumbuka eggplant (nyika maruva mumushonga wemvura, wobva wabata petals padivi pendiro kuti madonhwe akawandisa anoyerera mundiro).
③ Ne 1 kusvika 5 mg/kg yemushonga wemvura, pfapfaidza maruva maruva ebhinzi, pfapfaidza kamwe chete mazuva gumi, pfapfaidza kaviri.
④ Munguva yematsutso cowpea inotumbuka, ine 4 kusvika 5 mg/kg yemushonga wemvura, pfapfaidza maruva, pfapfaidza kamwe chete mazuva mana kusvika mashanu.
⑤Kana 2/3 yemaruva yakavhurika pane imwe neimwe inflorescence yematomatisi, pfapfaidza maruva ne20 kusvika 30 mg/kg yemushonga wemvura.

⑥ Munguva yekutumbuka kwemazambiringa, pfapfaidza 25 kusvika 30 mg/kg yemushonga wemvura.
⑦ Kana magaka maruva echikadzi avhurwa, pfapfaidza maruva ne25 ~ 40 mg/kg yemushonga wemvura.
⑧ Mazuva matatu mushure mekutumbuka (kupisa) mhiripiri, pfapfaidza maruva ne30 kusvika 50 mg/kg yemushonga wemvura.
⑨ Munguva yekutumbuka kwegadzi jena, pfapfaidza maruva ne60 ~ 80 mg/kg yemushonga wemvura.
(2) Kuwedzera kugadzikana: mazuva matatu kusvika gumi pamberi pekukohwa Chinese kabichi, sarudza masikati ezuva, ane 40 kusvika 100 mg/kg yemushonga wemvura, pfapfaidza kubva pasi uchikwira kubva pasi peChinese cabbage, nemashizha akanyorova uye mushonga wemvura hausi kudonha, unogona kuderedza nguva yekuchengetedza yeChinese kabichi shizha.

Nyaya dzinoda kutarisirwa

(1) Rega kushandisa muriwo kwasara mazuva matatu kukohwa.Izvo zvakachengeteka kushandisa pane 2, 4-madonhwe.Shandisa kamupfapfaidzo kadiki (sekupfapfaidza pahuro) kupfapfaidza maruva uye kudzivirira kupfapfaidza panhungirwa nepfungi.Nyatsodzora chipimo chemushonga, kuisa pfungwa uye nguva yenguva yemishonga kudzivirira kukuvara kwezvinodhaka.
(2) Dzivisa kushandisa mushonga mumazuva anopisa, kupisa uye kunaya kudzivirira kukuvara kwezvinodhaka.Usashandise mumiririri uyu pamiriwo yakachengetwa.

Kuchengetedza mamiriro

Kuchengetedza mamiriro 0-6 ° C;Chisimbiso uye chitoro chakaoma.Warehouse ventilation uye yakaderera tembiricha kuomesa;Chengetedza uye kutakura zvakasiyana kubva kune chikafu chekudya.

Kugadzirira nzira

Inowanikwa ne condensation ye phenol uye chloroacetic acid uye chlorination.1. Condensation iyo phenol yakanyungudutswa inosanganiswa ne15% sodium hydroxide solution, uye chloroacetic acid aqueous solution inogadziriswa ne sodium carbonate.Izvo zviviri zvinosanganiswa muhari yekupindura uye inopisa reflux kwe4h.Mushure mekuita, wedzera hydrochloric acid kune pH ye2-3, simbisa uye kutonhora, crystallize, sefa, geza mumvura yechando, yakaoma, phenoxyacetic acid inowanikwa.2. Chlorination Sanganisa phenoxyacetic acid uye glacial acetic acid kuti inyunguduke, wedzera mapiritsi ayodhine, uye bvisa chlorine pa26-34 ℃.Mushure mekupera kweklorini, isa usiku hwose, zuva rinotevera mumvura inotonhora crystallization, sefa, geza nemvura kusvikira yasarerekera, yakaoma yakapera zvigadzirwa.
