Umhlinzeki waseShayina Pgr Umlawuli Wokukhula Kwezitshalo 4 I-Chlorophenoxyacetic Acid Sodium 4CPA 98% Tc

Ububanzi besicelo

I-P-chlorophenoxyacetic acid ilawula ukukhula kwezitshalo ze-phenoxyl ezinomsebenzi we-auxin. Isetshenziswa kakhulu ukuvimbela ukuwa kwezimbali nezithelo, ukuvimbela imidumba ukuthi ingagxili, ukukhuthaza ukwakheka kwezithelo, ukukhuthaza izithelo ezingenayo i-drupe, nokukhuthaza ukukhula kokuvuthwa.

Indlela yokusebenzisa

Kala kahle igremu eli-1 le-sodium chloropenoxate, uyifake ebhodleleni (noma engilazini encane), engeza inani elincane lamanzi ashisayo noma i-95% alcohol, uyivuselele njalo ngenduku yengilazi kuze kube yilapho incibilika ngokuphelele, bese ufaka amanzi ku-500 ml, okungukuthi, ukuze ibe yi-2000 ml/kg yesisombululo sesitokisi esilwa nokuwa. Uma isetshenziswa, kuyalulekwa ukuthi unciphise inani elithile lesisombululo sesitokisi ngamanzi kuze kube yilapho kudingeka khona ukuze kufefwe, kucwiliswe, njll.
(1) Vimbela ukuwa kwezimbali nezithelo:
① Ngaphambi nangemva kuka-9 ekuseni, cwilisa izimbali zesifazane ze-zucchini ezivulekile ngomuthi owuketshezi ongu-30 kuya ku-40 mg/kg.
②Faka u-30 kuya ku-50 mg/kg womuthi owuketshezi esitsheni esincane, bese ucwilisa izimbali ekuseni ngosuku lokuqhakaza kweqanda (cwilisa izimbali emuthini owuketshezi, bese uthinta amacembe ohlangothini lwesitsha ukuze amaconsi angaphezulu ageleze esitsheni).
③ Ngomuthi owuketshezi ongu-1 kuya ku-5 mg/kg, fafaza i-inflorescence eqhakazayo yobhontshisi, fafaza kanye njalo ezinsukwini eziyi-10, fafaza kabili.
④ Ngesikhathi sokuqhakaza kwezimbali ze-cowpea ekwindla, faka umuthi owuketshezi ongu-4 kuya ku-5 mg/kg, ufafaze izimbali, ufafaze kanye njalo ezinsukwini ezi-4 kuya kwezi-5.
⑤Uma izimbali ezingu-2/3 sezivuliwe ku-inflorescence ngayinye katamatisi, fafaza izimbali ngomuthi owuketshezi ongu-20 kuya ku-30 ​​mg/kg.

⑥ Ngesikhathi sokuqhakaza kwamagilebhisi, fafaza ngo-25 kuya ku-30 ​​mg/kg womuthi owuketshezi.
⑦Uma izimbali zesifazane zekhukhamba zivuleka, fafaza izimbali ngomuthi owuketshezi ongu-25 ~ 40 mg/kg.
⑧ Ezinsukwini ezi-3 ngemva kokuqhakaza izimbali ezimnandi (ezishisayo), fafaza izimbali ngomuthi owuketshezi ongu-30 kuya ku-50 mg/kg.
⑨ Ngesikhathi sokuqhakaza kwe-gourd emhlophe yesifazane, fafaza izimbali ngomuthi owuketshezi ongu-60 ~ 80 mg/kg.
(2) Thuthukisa ukugcinwa: Ezinsukwini ezi-3 kuya kweziyi-10 ngaphambi kokuvunwa kweklabishi laseShayina, khetha ntambama enelanga, enomuthi owuketshezi ongu-40 kuya ku-100 mg/kg, fafaza kusukela phansi kuya phezulu kusukela phansi kweklabishi laseShayina, amaqabunga emanzi futhi umuthi owuketshezi ungaconsi, kunganciphisa isikhathi sokugcina iqabunga leklabishi laseShayina.

Izindaba ezidinga ukunakwa

(1) Yeka ukusebenzisa imifino ezinsukwini ezi-3 ngaphambi kokuvuna. Kuphephile ukuyisebenzisa kunezinhlayiya ezimbili, ezine. Sebenzisa isifutho esincane (njengesifutho somphimbo wezokwelapha) ukuze ufafaze izimbali futhi ugweme ukufafaza emahlumela nasemahlumela. Lawula ngokuqinile umthamo, ukuhlushwa kanye nobude bomuthi ukuze uvimbele ukulimala komuthi.
(2) Gwema ukusebenzisa umuthi ezinsukwini ezishisayo, ezishisayo nezinemvula ukuze uvimbele umonakalo wemithi. Ungasebenzisi lesi sidakamizwa emifinweni egciniwe.

Isimo sesitoreji

Izimo zokugcina 0-6°C; Vala futhi womise isitolo. Umoya wokungenisa umoya e-warehouse kanye nokomisa okuphansi kwezinga lokushisa; Gcina futhi uthuthe ngokwehlukana nezinto zokusetshenziswa zokudla.

Indlela yokulungiselela

Itholakala ngokujiya kwe-phenol kanye ne-chloroacetic acid kanye ne-chlorination. 1. Ukujiya i-phenol encibilikisiwe ixutshwa nesisombululo se-sodium hydroxide esingu-15%, bese isisombululo samanzi se-chloroacetic acid sincishiswa nge-sodium carbonate. Lokhu kokubili kuxutshwa ebhodweni lokusabela bese kufudunyezwa ukuze kubuyiselwe emuva amahora ama-4. Ngemva kokusabela, engeza i-hydrochloric acid ku-pH engu-2-3, uvuselele bese upholisa, ucwebe, uhlunge, ugeze emanzini eqhwa, womise, kutholakale i-phenoxyacetic acid. 2. I-Chlorination Hlanganisa i-phenoxyacetic acid kanye ne-glacial acetic acid ukuze kuncibilike, engeza amaphilisi e-iodine, bese ususa i-chlorine ku-26-34℃. Ngemva kokuphela kwe-chlorine, faka ubusuku bonke, ngosuku olulandelayo ku-crystallization yamanzi abandayo, uhlunge, ugeze ngamanzi kuze kube yilapho imikhiqizo eqediwe ingathathi hlangothi, yomile.
