Mutengesi weChina Pgr Plant Growth Regulator 4 Chlorophenoxyacetic Acid Sodium 4CPA 98% Tc
Mashandisirwo ekushandisa
P-chlorophenoxyacetic acid inodzora kukura kwezvirimwa zvephenoxyl zvine auxin activity. Inonyanya kushandiswa kudzivirira kudonha kwemaruva nemichero, kudzivirira midzi yembeu, kukurudzira kumera kwemichero, kukurudzira michero isina drupe, uye kukurudzira kukura kwemichero.
Nzira yekushandisa
Yera 1 gram ye sodium chloropenoxate nemazvo, isa mubeaker (kana girazi diki), wedzera mvura inopisa shoma kana 95% alcohol, ramba uchikurunga negirazi rod kusvika yanyungudika zvachose, wobva wawedzera mvura ku500 ml, kureva kuti, kuti ive 2000 ml/kg ye anti-fall stock solution. Kana ikashandiswa, zvinokurudzirwa kuti uderedze huwandu hwakati hwe stock solution nemvura kusvika pakuwanda kunodiwa pakupfapfaidza, kunyudza, nezvimwewo.
(1) Kudzivirira kudonha kwemaruva nemichero:
① Musati matanga uye mushure ma9am, nyikai maruva echikadzi ezucchini akavhurika ne30 kusvika 40 mg/kg yemushonga wemvura.
②Isa 30 kusvika 50 mg/kg yemushonga wemvura mundiro diki, wonyika maruva mangwanani ezuva rekutumbuka kwemaeggplant (nyika maruva mumushonga wemvura, wobva wabata petals dziri padivi pendiro kuti madonhwe akawandisa ayerere mundiro).
③ Ne 1 kusvika 5 mg/kg yemushonga wemvura, pfapfaidza maruva ebhinzi, pfapfaidza kamwe chete pamazuva gumi, pfapfaidza kaviri.
④ Munguva yemwaka wekudonha kwembeu dzemumatsutso, pfupfaidzai maruva ne4 kusvika 5 mg/kg yemushonga wemvura, pfapfaidzai maruva, pfapfaidzai kamwe chete pamazuva mana kusvika mashanu ega ega.
⑤Kana 2/3 yemaruva yavhurika pamaruva ese edomasi, pfapfaidza maruva ne20 kusvika 30 mg/kg yemushonga wemvura.
⑥ Munguva yemaruva emazambiringa, pfapfaidza mushonga wemvura 25 kusvika 30 mg/kg.
⑦Kana maruva echikadzi emucucumber avhurwa, pfapfaidza maruva ne 25 ~ 40 mg/kg yemushonga wemvura.
⑧ Mazuva matatu mushure memaruva emushonga unotapira (unopisa), pfapfaidza maruva ne30 kusvika 50 mg/kg yemushonga wemvura.
⑨ Munguva yemaruva egondo jena rechikadzi, pfapfaidza maruva ne60 ~ 80 mg/kg yemushonga wemvura.
(2) Wedzera kugona kuchengetwa: Mazuva matatu kusvika gumi kukohwa kabichi reChinese kusati kwasvika, sarudza masikati ane zuva, ne40 kusvika 100 mg/kg yemushonga wemvura, pfapfaidza kubva pasi uchikwira kubva pasi pekabheji reChinese, mashizha akanyorova uye mushonga wemvura usiri kudonha, zvinogona kuderedza nguva yekuchengetwa kwemashizha ekabheji reChinese.
Nyaya dzinoda kutariswa
(1) Rega kushandisa miriwo mazuva matatu usati wakohwa. Zvakachengeteka kushandisa pane madonhwe maviri, mana. Shandisa sprayer diki (yakadai se medical throat sprayer) kupfapfaidza maruva uye kudzivirira kupfapfaidza padzinde nedzinde. Dzora zvakanyanya mwero, huwandu hwemushonga uye nguva yemushonga kudzivirira kukuvara kwemushonga.
(2) Dzivisa kushandisa mushonga pamazuva anopisa, anopisa uye emvura kudzivirira kukuvara kwemishonga. Usashandise mushonga uyu pamiriwo yakachengetwa.
Mamiriro ekuchengetedza
Mamiriro ekuchengetera 0-6°C; Vhara uye omesa chitoro. Kufefetera kwemudura uye kuomesa tembiricha yakaderera; Chengeta uye kutakura zvakasiyana nezvinhu zvekudya.
Nzira yekugadzirira
Inowanikwa nekusanganiswa kwe phenol ne chloroacetic acid uye chlorination. 1. Kusanganiswa kwe phenol yakanyungudutswa inosanganiswa ne 15% sodium hydroxide solution, uye chloroacetic acid aqueous solution inobviswa ne sodium carbonate. Zvose izvi zvinosanganiswa muhari ye reaction uye zvinodziiswa kuti zviome kwemaawa mana. Mushure me reaction, wedzera hydrochloric acid ku pH ye 2-3, kurunga wotonhodza, simbisa, sefa, sukurudza mumvura yechando, omesa, phenoxyacetic acid inowanikwa. 2. Chlorination Sanganisa phenoxyacetic acid ne glacial acetic acid kuti inyungudike, wedzera mapiritsi e iodine, uye bvisa chlorine pa 26-34℃. Mushure mekupera kwe chlorine, isa husiku, zuva rinotevera mumvura inotonhora crystallization, sefa, sukurudza nemvura kusvika zvigadzirwa zvapera zvisina neutral, zvakaoma.
