Ukusetshenziswa okuyinhloko kwe-4-Chlorophenoxyacetic acid (4-CPA)
I-4-Chlorophenoxyacetic acid (4-CPA) iyisilawuli sokukhula kwesitshalo se-phenolic. I-4-Chlorophenoxyacetic acid (4-CPA) ingamuncwa izimpande, iziqu, amaqabunga, izimbali, nezithelo zezitshalo. Umsebenzi wayo webhayoloji uhlala isikhathi eside. Imiphumela yayo yomzimba ifana namahomoni angapheli, akhuthaza ukuhlukana kwamaseli kanye nokuhlukaniswa kwezicubu, okukhuthaza ukwanda kwe-ovary, ukugqugquzela i-parthenocarpy, ukwakha izithelo ezingenambewu, nokukhuthaza ukumiswa kwezithelo nokwanda kwezithelo.
[Sebenzisa 1]Isetshenziswa njengesilawuli sokukhula kwezitshalo, i-fruit drop preventer, i-herbicide, ingasetshenziselwa ukunciphisa izimbali zikatamatisi kanye nokunciphisa izithelo zepentshisi.
[Sebenzisa 2]I-hormone yokukhula yezitshalo, esetshenziswa njengesilawuli sokukhula, isivimbeli sokudonsa izithelo, i-herbicide, ingasetshenziselwa utamatisi, imifino, izihlahla zamapentshisi, njll. I-4-Chlorophenoxyacetic acid (4-CPA) isicelo esiyinhloko i-4-Chlorophenoxyacetic acid (4-CPA) isetshenziswa kakhulu ukuvimbela ukuwohloka kwembali nezithelo, ukuvimbela ukumila kwezimpande zikabhontshisi, ukukhuthaza ukumiswa kwezithelo, ukukhiqiza izithelo ezingenambewu, futhi kunomphumela wokuvuthwa nokukhula. . I-4-Chlorophenoxyacetic acid (i-4-CPA ingamuncwa izimpande, iziqu, izimbali nezithelo, futhi umsebenzi wayo webhayoloji uhlala isikhathi eside. Ukugxila kokusetshenziswa kungu-5-25ppm, futhi i-trace elements noma i-0.1% ye-potassium dihydrogen phosphate ingangezwa ngokufanelekile Kunomphumela omuhle wokuvimbela isikhunta esimpunga, futhi ukugxila kokusetshenziswa okujwayelekile kungu-50-80ppm.
1. Ukukhuphuka kwesivuno kusenesikhathi kanye nokuvuthwa kwangaphambi kwesikhathi.
Isebenza ezitshalweni ezinama-ovules amaningi, njengotamatisi, ama-eggplant, amakhiwane, amakhabe, i-zucchini, njll. Futha ama-eggplant ngo-25-30 mg/L 4-Chlorophenoxyacetic acid (isixazululo se-4-CPA ngesikhathi sokuqhakaza, kabili ngokulandelana, ngesikhawu seviki eli-1 isikhathi ngasinye Uma utamatisi usuphakathi nokuqhakaza, fafaza ngo-25-30 mg/L 4-Chlorophenoxyacetic acid (isixazululo esingu-4-CPA kanye. Upelepele ufafazwa ngo-15-25 mg/L 4-Chlorophenoxyacetic acid (4-CPA isixazululo kanye ngesikhathi sokuqhakaza.
2. I-4-Chlorophenoxyacetic acid (i-4-CPA isetshenziswa kugwayi ukunciphisa okuqukethwe kwe-nicotine.
3. I-4-Chlorophenoxyacetic acid (i-4-CPA isetshenziselwa izimbali zokuhlobisa ukwenza izimbali zikhule ngamandla, zandise izimbali ezintsha nezithelo, futhi zandise isikhathi sokuqhakaza.
4. 4-Chlorophenoxyacetic acid Acid (4-CPA isetshenziselwa ukolweni, ummbila, ilayisi, ubhontshisi nezinye izitshalo zokusanhlamvu. Ingavimbela amagobolondo angenalutho. Ingakwazi ukuzuza okusanhlamvu okugcwele, ukukhuphuka kwezinga lokubeka izithelo, isivuno esikhulayo, isivuno esikhulu kanye nokuqala. ukuvuthwa.
5. Khulisa isivuno semifino nezithelo ezahlukene. Isibonelo, izinga lokumisa izithelo likatamatisi liyathuthukiswa. Isivuno sokuqala siyakhula futhi isikhathi sokuvuna sisekuqaleni. Ikhabe liyafuthwa, isivuno siyakhula, umbala muhle, isithelo sikhulu, okuqukethwe ushukela kanye ne-vitamin C kuphezulu, futhi imbewu incane. Ngesikhathi sokuqhakaza kwekhabe, i-20 mg/L yesisombululo se-anti-drop ifafazwa izikhathi ezi-1 kuya kwezi-2, futhi izikhathi ezi-2 zidinga ukuhlukaniswa. Eklabishini laseShayina, u-25-35 mg/L we-4-Chlorophenoxyacetic acid (isixazululo se-4-CPA ufafazwa ntambama ngosuku olushisayo ezinsukwini ezi-3-15 ngaphambi kokuvuna, okungavimbela iklabishi ukuthi liwe ngesikhathi sokugcinwa futhi ine umphumela wokugcina omusha.
6. I-4-Chlorophenoxyacetic acid (i-4-CPA isetshenziselwa ukutshala amahlumela kabhontshisi angenazimpande.
Izinyathelo zokuphepha zokusebenzisa i-4-CPA
(1) Yeka ukuyisebenzisa ezinsukwini ezi-3 ngaphambi kokuvuna imifino.
Le ejenti iphephile kuno-2,4-D. Kutuswa ukuthi usebenzise isifutho esincane ufafaze izimbali (njengesifafazi somphimbo wezokwelapha) futhi ugweme ukufafaza emagatsheni amathenda kanye nemiqumbe emisha. Lawula ngokuqinile umthamo, ukugxilisa ingqondo nesikhathi sokufaka isicelo ukuze uvimbele ukulimala kwezidakamizwa.
(2) Gwema ukufaka isicelo ngezinsuku ezishisayo nezishisayo noma izimvula ukuze uvimbele ukulimala kwezidakamizwa.
Lesi senzo asikwazi ukusetshenziswa ezitshalweni ukwenza imbewu.
