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

Ubungakanani besicelo

I-P-chlorophenoxyacetic acid ngumlawuli wokukhula kwezityalo ze-phenoxyl kunye nomsebenzi we-auxin.Isetyenziswa kakhulu ukunqanda ukuwa kwentyatyambo kunye neziqhamo, inqanda iimbotyi ekukhuleni kweengcambu, ikhuthaza ukumila kweziqhamo, ikhuthaze iziqhamo ezingenayo idrupe, kwaye ikhuthaze ukukhula.

Indlela yokusetyenziswa

Ukulinganisa ngokuchanekileyo igram ye-sodium chloropenoxate, uyibeke kwi-beaker (okanye iglasi encinci), yongeza inani elincinci lamanzi ashushu okanye i-95% yotywala, uyigxobhoze ngokuqhubekayo ngentonga yeglasi de inyibilike ngokupheleleyo, uze udibanise amanzi kwi-500. ml, oko kukuthi, ukuba yi-2000 ml / kg yesisombululo se-anti-fall stock.Xa kusetyenziswe, kuyacetyiswa ukuba uhlambulule umlinganiselo othile wesisombululo sesitokhwe ngamanzi ukuya kugxininiso olufunekayo lokutshiza, ukuntywila, njl.
(1) Thintela ukuwa kweentyatyambo neziqhamo:
① Phambi nasemva kwentsimbi yesi-9 kusasa, dipha iintyatyambo zasemazi yezucchini ezivulekileyo nge-30 ukuya kwi-40 mg/kg yeyeza elingamanzi.
②Faka i-30 ukuya kwi-50 mg/kg yamayeza angamalwelo kwisitya esincinci, kwaye uyithi nkxu iintyatyambo ngentsasa yosuku lweentyantyambo ze-eggplant (dipha iintyatyambo kwiyeza elingamanzi, kwaye emva koko uchukumise iipetali ezisecaleni kwesitya ukuze uvule amathontsi angaphezulu angena kwisitya).
③ Nge-1 ukuya kwi-5 mg/kg yeyeza elingamanzi, fafaza intyantyambo yeembotyi, tshiza kanye ngeentsuku ezili-10, utshize kabini.
④ Ngexesha leentyantyambo zasekwindla ze-cowpea, kunye ne-4 ukuya kwi-5 mg/kg yeyeza elingamanzi, tshiza iintyatyambo, utshize kanye ngeentsuku ezi-4 ukuya kwezi-5.
⑤Xa i-2/3 yeentyatyambo ivulekile kwi-inflorescence nganye yetumata, fafaza iintyatyambo nge-20 ukuya kwi-30 mg/kg yeyeza elingamanzi.

⑥ Ngexesha lokudumba kweediliya, fafaza nge 25 ukuya kwi 30 mg/kg yamayeza angamalwelo.
⑦Xa ikhukhamba iintyatyambo ezimazi zivulekile, fafaza iintyatyambo nge-25 ~ 40 mg/kg yeyeza elingamanzi.
⑧ Kwiintsuku ezi-3 emva kokutyatyamba kwepepile eswiti (eshushu), fafaza iintyatyambo nge-30 ukuya kwi-50 mg/kg yeyeza elingamanzi.
⑨ Ngexesha lokudubula kwemazi yethanga elimhlophe, fafaza iintyatyambo nge-60 ~ 80 mg/kg yeyeza elingamanzi.
(2) Ukuphucula ukugcina: kwiintsuku ezi-3 ukuya kwezi-10 ngaphambi kokuvunwa kwekhaphetshu yaseTshayina, khetha imvakwemini enelanga, kunye ne-40 ukuya kwi-100 mg/kg yeyeza elimanzi, fafaza ukusuka ezantsi ukuya phezulu ukusuka kwisiseko sekhaphetshu yaseTshayina, ngamagqabi amanzi kwaye. iyeza lolwelo alivuzi, linokunciphisa ixesha lokugcinwa kwegqabi lekhaphetshu laseTshayina.

Imibandela efuna ingqalelo

(1) Yeka ukusebenzisa imifuno kwiintsuku ezi-3 phambi kokuvuna.Kukhuselekile ukusebenzisa kune-2, 4-drops.Sebenzisa isitshizi esincinci (njengesitshizi somqala sonyango) ukutshiza iintyatyambo kwaye uphephe ukutshiza kuhlumelo kunye nehlumela.Lawula ngokungqongqo idosi, ukugxininiswa kunye nobude bechiza ukuthintela umonakalo weziyobisi.
(2) Kuphephe ukusebenzisa iyeza ngeentsuku ezishushu, ezishushu nezinethayo ukuthintela ukonakala kweziyobisi.Musa ukusebenzisa le arhente kwimifuno egciniweyo.

Imeko yokugcina

Iimeko zokugcina 0-6 ° C;Vala kunye nevenkile eyomileyo.Ukungena komoya kwindawo yokugcina impahla kunye nokomisa ubushushu obuphantsi;Gcina kwaye uthuthe ngokwahlukeneyo kwizinto ezidliwayo zokutya.

Indlela yokulungiselela

Ifunyenwe ngokucondelwa kwephenol kunye ne-chloroacetic acid kunye ne-chlorination.1. I-Condensation i-phenol enyibilikisiweyo ixutywe kunye ne-15% yesisombululo se-sodium hydroxide, kunye ne-chloroacetic acid isisombululo se-aqueous singathathi hlangothi kunye ne-sodium carbonate.Ezi zimbini zixutywe kwi-potreaction pot kwaye zifudumeze i-reflux ye-4h.Emva kokuphendula, yongeza i-hydrochloric acid kwi-pH ye-2-3, igxobhoze kwaye ipholile, i-crystallize, ihluzo, uhlambe emanzini e-ice, owomileyo, i-phenoxyacetic acid ifunyenwe.2. I-Chlorination Mix i-phenoxyacetic acid kunye ne-glacial acetic acid ukunyibilika, yongeza iipilisi ze-iodine, kwaye ususe i-chlorine kwi-26-34℃.Emva kokuphela kweklorini, faka ubusuku bonke, ngosuku olulandelayo emanzini abandayo, i-crystallization, ihluzo, uhlambe ngamanzi kuze kube yilapho ingathathi hlangothi, imveliso egqityiweyo eyomileyo.
