Umlawuli wokukhula kwezityalo waseTshayina uPgr 4 Chlorophenoxyacetic Acid Sodium 4CPA 98% Tc

Ububanzi besicelo

I-P-chlorophenoxyacetic acid yi-administrator yokukhula kwezityalo ze-phenoxyl enomsebenzi we-auxin. Isetyenziswa kakhulu ukuthintela ukuwa kweentyatyambo neziqhamo, ukuthintela iimbotyi ukuba zingamili iingcambu, ukukhuthaza ukubekwa kweziqhamo, ukukhuthaza iziqhamo ezingenayo i-drupe, kunye nokukhuthaza ukukhula kokuvuthwa.

Indlela yokusebenzisa

Linganisa ngokuchanekileyo i-1 gram ye-sodium chloropenoxate, uyibeke kwi-beaker (okanye kwiglasi encinci), yongeza amanzi ashushu amancinci okanye i-95% ye-alcohol, uyixube rhoqo nge-glass rod ide inyibilike ngokupheleleyo, uze wongeze amanzi kwi-500 ml, oko kukuthi, ukuze ibe yi-2000 ml/kg yesisombululo se-anti-fall stock. Xa isetyenziswa, kuyacetyiswa ukuba unciphise inani elithile lesisombululo se-stock ngamanzi ukuya kumlinganiselo ofunekayo wokutshiza, ukuntywila, njl.njl.
(1) Nqanda ukuwa kweentyatyambo neziqhamo:
① Ngaphambi nasemva kwentsimbi ye-9 kusasa, cwilisa iintyatyambo ze-zucchini ezivulekileyo kunye ne-30 ukuya kwi-40 mg/kg yeyeza elilulwelo.
②Faka i-30 ukuya kwi-50 mg/kg yeyeza lolwelo kwisitya esincinci, uze untywilisele iintyatyambo kusasa ngemini yokudubula kwe-eggplant (ntywilisela iintyatyambo kwiyeza lolwelo, uze uchukumise iipetali ecaleni kwesitya ukuze amathontsi angaphezulu angene kwisitya).
③ Nge-1 ukuya kwi-5 mg/kg yeyeza elilulwelo, fafaza i-inflorescence etyatyambileyo yeembotyi, fafaza kanye emva kweentsuku ezili-10, fafaza kabini.
④ Ngexesha lokudubula kweenkowane zasekwindla, faka i-4 ukuya kwi-5 mg/kg yeyeza elilulwelo, fafaza iintyatyambo, fafaza kube kanye emva kweentsuku ezi-4 ukuya kwezi-5.
⑤Xa i-2/3 yeentyatyambo ivuliwe kwi-inflorescence nganye yetumato, fafaza iintyatyambo nge-20 ukuya kwi-30 mg/kg yeyeza lolwelo.

⑥ Ngexesha lokudubula kweediliya, fafaza nge-25 ukuya kwi-30 mg/kg yeyeza elilulwelo.
⑦Xa iintyatyambo zekomkomere ezibhinqileyo zivulwa, fafaza iintyatyambo nge-25 ~ 40 mg/kg yeyeza elilulwelo.
⑧ Emva kweentsuku ezi-3 emva kokuba kuvele ipepile emnandi (eshushu), fafaza iintyatyambo nge-30 ukuya kwi-50 mg/kg yeyeza elilulwelo.
⑨ Ngexesha lokudubula kwegourd emhlophe yemazi, fafaza iintyatyambo nge-60 ~ 80 mg/kg yeyeza lolwelo.
(2) Ukuphucula ukugcinwa: kwiintsuku ezi-3 ukuya kwezili-10 ngaphambi kokuvunwa kwekhaphetshu yaseTshayina, khetha imva kwemini enelanga, kunye ne-40 ukuya kwi-100 mg/kg yeyeza lolwelo, fafaza ukusuka ezantsi ukuya phezulu ukusuka kwisiseko sekhaphetshu yaseTshayina, amagqabi emanzi kwaye iyeza lolwelo lingathontsi, kunokunciphisa ixesha lokugcina igqabi lekhaphetshu yaseTshayina.

Imiba efuna ingqwalasela

(1) Yeka ukusebenzisa imifuno kwiintsuku ezi-3 ngaphambi kokuvuna. Kukhuselekile ukuyisebenzisa kune-2, 4-drops. Sebenzisa i-sprayer encinci (njenge-medical throat sprayer) ukutshiza iintyatyambo kwaye uphephe ukutshiza kumahlumela nakwimihlumela. Lawula ngokungqongqo umthamo, uxinaniso kunye nobude beyeza ukuthintela umonakalo kwiyeza.
(2) Kuphephe ukusebenzisa amayeza ngeentsuku ezishushu, ezishushu nezinemvula ukuthintela umonakalo kwiziyobisi. Musa ukuyisebenzisa le arhente kwimifuno egciniweyo.

Imeko yokugcina

Iimeko zokugcina 0-6°C; Vala kwaye womise ivenkile. Umoya ongenisa umoya kwindawo yokugcina impahla kunye nokomisa kubushushu obuphantsi; Gcina kwaye uthuthe ngokwahlukileyo kwizinto zokutya ezikrwada.

Indlela yokulungiselela

Ifunyanwa ngokudityaniswa kwe-phenol kunye ne-chloroacetic acid kunye ne-chlorination. 1. Ukuxinana kwe-phenol enyibilikisiweyo kuxutywe nesisombululo se-sodium hydroxide se-15%, kwaye isisombululo samanzi se-chloroacetic acid sincitshiswa nge-sodium carbonate. Ezi zimbini zixutywa kwimbiza yokusabela kwaye zifudunyezwe ukuze ziphinde zibuyele esiqhelweni kangangeeyure ezi-4. Emva kokusabela, yongeza i-hydrochloric acid kwi-pH ye-2-3, uvuselele kwaye upholise, uqinise, uhluze, uhlambe emanzini abandayo, yomise, i-phenoxyacetic acid ifunyenwe. 2. I-Chlorination Xuba i-phenoxyacetic acid kunye ne-glacial acetic acid ukuze inyibilike, yongeza iipilisi ze-iodine, kwaye ususe i-chlorine kwi-26-34℃. Emva kokuphela kwe-chlorine, faka ubusuku bonke, ngosuku olulandelayo kwi-crystallization yamanzi abandayo, uhluze, uhlambe ngamanzi de iimveliso ezigqityiweyo zome kwaye zingathathi cala.
