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

Ububanzi besicelo

I-P-chlorophenoxyacetic acid isilawuli sokukhula sezitshalo ze-phenoxyl ezinomsebenzi we-auxin.Isetshenziselwa ikakhulukazi ukuvimbela izimbali nezithelo eziwayo, ukuvimbela imidumba ekukhuleni kwezimpande, ikhuthaze ukumiswa kwezithelo, ikhuthaze izithelo ezingena-drupe, futhi ikhuthaze ukukhula kokuvuthwa.

Indlela yokusebenzisa

Kala ngokunembile igremu elingu-1 le-sodium chloropenoxate, uyibeke ebhekileni (noma ingilazi encane), engeza amanzi ashisayo amancane noma u-95% wotshwala, uwugqugquzele ngokuqhubekayo ngenduku yengilazi uze uhlakazeke ngokuphelele, bese wengeza amanzi ku-500. ml, okungukuthi, ukuba ngu-2000 ml/kg wesisombululo sesitoko esilwa nokuwa.Uma kusetshenziswe, kuhle ukuhlambulula inani elithile lesisombululo sesitoko ngamanzi ekugxiliseni okudingekayo kokufafaza, ukucwiliswa, njll.
(1) Vimbela ukuwa kwezimbali nezithelo:
① Ngaphambi nangemuva kuka-9 am, cwilisa izimbali zesifazane ezivulekile ze-zucchini ngomuthi owuketshezi ongu-30 kuya ku-40 mg/kg.
②Faka u-30 kuya ku-50 mg/kg womuthi owuketshezi endishini encane, bese ucwilisa izimbali ekuseni ngosuku lokuqhakaza kwesitshalo seqanda (cwilisa izimbali emuthini owuketshezi, bese uthinta amacembe asohlangothini lwesitsha ukuze uvumele amaconsi engeziwe ageleza endishini).
③ Ngo-1 kuya ku-5 mg/kg womuthi owuketshezi, fafaza i-inflorescence eqhakazayo kabhontshisi, fafaza kanye njalo ezinsukwini eziyi-10, fafaza kabili.
④ Esikhathini sokuqhakaza kwe-cowpea ekwindla, ngo-4 kuya ku-5 mg/kg womuthi owuketshezi, fafaza izimbali, fafaza kanye njalo ezinsukwini ezi-4 kuya kwezi-5.
⑤Uma u-2/3 wezimbali evulekile ku-inflorescence ngayinye katamatisi, fafaza izimbali ngo-20 kuya ku-30 ​​mg/kg womuthi owuketshezi.

⑥ Ngesikhathi sokuqhakaza kwamagilebhisi, fafaza ngomuthi owuketshezi ongu-25 kuya ku-30 ​​mg/kg.
⑦Uma izimbali ze-cucumber female zivuleka, fafaza izimbali ngo-25 ~ 40 mg/kg womuthi owuketshezi.
⑧ Ezinsukwini ezi-3 ngemuva kokuqhakaza kukapelepele omnandi (oshisayo), fafaza izimbali ngo-30 kuya ku-50 mg/kg womuthi owuketshezi.
⑨ Ngesikhathi sokuqhakaza kokhava olumhlophe wesifazane, fafaza izimbali ngomuthi owuketshezi ongu-60 ~ 80 mg/kg.
(2) Khulisa ukuqina: ezinsukwini ezi-3 kuya kweziyi-10 ngaphambi kokuvunwa kweklabishi laseShayina, khetha intambama enelanga, no-40 kuya ku-100 mg/kg womuthi owuketshezi, fafaza usuka phansi uye phezulu usuka phansi kweklabishi laseShayina, amaqabunga abemanzi futhi. umuthi owuketshezi awuconsi, unganciphisa isikhathi sokugcinwa kweqabunga leklabishi laseShayina.

Izindaba ezidinga ukunakwa

(1) Yeka ukusebenzisa imifino ezinsukwini ezi-3 ngaphambi kokuvuna.Kuphephile ukusebenzisa kunamaconsi angu-2, 4.Sebenzisa isifutho esincane (njengesifutho somphimbo sezokwelapha) ukufafaza izimbali futhi ugweme ukufafaza amahlumela namahlumela.Lawula ngokuqinile umthamo, ukugxila kanye nobude besikhathi somuthi ukuze uvimbele ukulimala kwezidakamizwa.
(2) Gwema ukusebenzisa umuthi ezinsukwini ezishisayo, ezishisayo nezina ukuze uvimbele ukulimala kwezidakamizwa.Ungayisebenzisi le ejenti emifino egodliwe.

Isimo sesitoreji

Izimo zokugcina 0-6°C;Vala futhi somile isitolo.Ukungena komoya endaweni yokugcina impahla kanye nokomisa izinga lokushisa eliphansi;Gcina futhi uthuthe ngokuhlukene nezinto ezingavuthiwe zokudla.

Indlela yokulungiselela

Itholakala ngokufingqa kwe-phenol ne-chloroacetic acid kanye ne-chlorination.1. Ukujiya i-phenol encibilikisiwe ixutshwa nesisombululo se-sodium hydroxide esingu-15%, bese isixazululo esinamanzi se-chloroacetic sincishiswa nge-sodium carbonate.Okubili kuxutshwe ebhodweni lokusabela futhi kushiselwe i-reflux amahora angu-4.Ngemuva kokusabela, engeza i-hydrochloric acid ku-pH ye-2-3, inyakaze futhi ipholile, icwebeze, isihlungi, ugeze emanzini eqhwa, owomile, i-phenoxyacetic acid itholakala.2. I-Chlorination Mix i-phenoxyacetic acid ne-glacial acetic acid ukuze incibilike, wengeze amaphilisi e-iodine, futhi ususe i-chlorine ku-26-34℃.Ngemuva kokuphela kwe-chlorine, faka ubusuku bonke, ngakusasa emanzini abandayo i-crystallization, isihlungi, ugeze ngamanzi kuze kube yilapho ungathathi hlangothi, imikhiqizo ephelile eyomile.
