Ukusetshenziswa Okusheshayo Okudumile kwe-Plant Hormone Thidiazuron 50% Sc CAS No. 51707-55-2

a. Lawula ukukhula futhi wandise isivuno
Esigabeni sokuhluma kanye nesigaba sokuqhakaza kwelayisi, i-3 mg/L thiazenon spray kanye ebusweni beqabunga ngalinye ingathuthukisa ikhwalithi yezimpawu zezolimo zelayisi, yandise inani lezinhlamvu nge-spike kanye nesilinganiso sokubeka imbewu, yehlise inani lezinhlamvu nge-spike, futhi yandise isivuno esiphezulu ngo-15.9%.
Amagilebhisi afuthwe nge-4 ~ 6 mg ye-L thiabenolon cishe ezinsukwini ezi-5 ngemva kokuwa kwezimbali, kanti okwesibili ngesikhawu sezinsuku eziyi-10 kungakhuthaza ukuvela kwezithelo nokuvuvukala futhi kwandise isivuno.
Ama-apula aphakathi kwesihlahla sama-apula aqhakaza ngo-10% kuya ku-20% kanye nesikhathi sokuqhakaza esigcwele, lapho kusetshenziswa umuthi we-thiabenolon ongu-2 kuya ku-4 mg/L kanye, angakhuthaza ukuvela kwezithelo.
Usuku olulodwa noma ngosuku olungaphambi kokuqhakaza, i-thiabenolon engu-4~6 mg/L yasetshenziswa ukucwilisa umbungu wekhabe kanye, okwakungakhuthaza ukwanda kwesivuno futhi kwandise izinga lekhabe elihlala phansi.

Isifutho sikatamatisi esingu-1 mg/L umuthi owuketshezi kanye ngaphambi kokuqhakaza futhi esigabeni sezithelo ezincane kungakhuthaza ukukhula kwezithelo futhi kwandise isivuno kanye nemali engenayo.
Ukucwilisa i-embryo yekhukhamba nge-thiabenolon engu-4~ 5 mg/L kanye ngaphambi kokuqhakaza noma ngosuku olufanayo kungakhuthaza ukuvela kwezithelo futhi kwandise isisindo sezithelo ezilodwa.
Ngemva kokuvuna i-celery, ukufafaza isitshalo sonke nge-1-10 mg/L kungabambezela ukuwohloka kwe-chlorophyll futhi kukhuthaze ukulondolozwa okuluhlaza.
Isisindo sesithelo esisodwa kanye nokukhiqizwa kwejujube kwanda lapho kusetshenziswa i-thiaphenone engu-0.15 mg/L kanye ne-gibberellic acid engu-10 mg/L ekuqhakazeni kokuqala, ekuweni kwezithelo zemvelo kanye nasekukhuleni kwezithelo ezincane.
b. Ama-defoliant
Uma ipentshisi likakotini liqhekeka ngaphezu kwama-60%, i-10 ~ 20 g/mu ye-tiphenuron ifuthwa ngokulinganayo emaqabungeni ngemva kwamanzi, okungakhuthaza ukubola kwamaqabunga.

Ukuqhathaniswa kwezinzuzo kanye nokungalungi kwe-thiaphenone kanyei-ethephonwedwa:

I-Ethephon: Umphumela wokuvuthwa kwe-ethephon ungcono, kodwa umphumela wokususwa kwamaqabunga awubi! Uma isetshenziswa kukotini, ingaqhekeka ngokushesha ipentshisi yekotini futhi yomise amaqabunga, kodwa kunezinzuzo eziningi kanye nokungalungi kwe-ethylene:

1, umphumela wokuvuthwa kwe-ethephon muhle, kodwa umphumela wokususwa kwamaqabunga awubi, wenza amaqabunga akheke “omile ngaphandle kokuwa”, ikakhulukazi lapho ukusetshenziswa kokuvuna ngomshini ukungcola kukakotini kuyinto embi kakhulu.

2, ngesikhathi esifanayo sokuvuthwa, isitshalo sikakotini naso salahlekelwa amanzi ngokushesha safa, kanti amahlumela amancane angaphezulu kukakotini nawo afa, futhi ukukhiqizwa kukakotini kwaba kubi kakhulu.

3, ukubhaxabula ikotini akukuhle, ukuqhekeka kwepentshisi likotini kulula ukwenza igobolondo, kunciphisa ukusebenza kahle kokuvuna, ikakhulukazi lapho kuvunwa ngomshini, kulula ukuvuna kungahlanzekile, ukwakheka kokuvuna kwesibili, kwandisa izindleko zokuvuna.

4, i-ethephon izothinta nobude befayibha kakotini, yehlise izinhlobo zikakotini, kube lula ukwakha ukotini ofile.

I-Thiabenolon: umphumela wokususwa kweqabunga le-thiabenolon muhle kakhulu, umphumela wokuvuthwa awumuhle njenge-ethephon, kuncike ezimweni zezulu (kukhona abakhiqizi ngabanye abanobuchwepheshe bokukhiqiza obungcono, ukukhiqizwa kwezithasiselo ezisebenzayo ze-thiabenolon, kunganciphisa kakhulu imikhawulo yesimo sezulu se-thiabenolon), kodwa ukusetshenziswa okufanele kuzodlala umphumela omuhle:

1, ngemva kokusebenzisa i-thiaphenone, ingenza isitshalo sikakotini ngokwaso sikhiqize i-abscisic acid kanye ne-ethylene, okuholela ekwakhekeni kwengqimba ehlukile phakathi kwe-petiole kanye nesitshalo sikakotini, ukuze amaqabunga kakotini awe wodwa.

2. I-Thiaphenone ingadlulisela izakhamzimba ngokushesha eziqongweni zekotini ezisencane engxenyeni engenhla yesitshalo ngenkathi amaqabunga eseluhlaza, futhi isitshalo sikakotini ngeke sife, sifinyelele ekuvuthweni, ekususweni kwamaqabunga, ekukhuleni kwesivuno, ekuthuthukisweni kwekhwalithi kanye nokuhlanganiswa kwemiphumela eminingi.

3, i-thiabenolon ingenza ukotini kusenesikhathi, i-cotton boll ishaya kusenesikhathi, igxilile, yandisa isilinganiso sekotoni ngaphambi kweqhwa. Ukotini awusikeki igobolondo, awuwisi udoti, awuwisi imbali, wandisa ubude befayibha, uthuthukisa ingxenye yengubo, uvumela ukuvunwa kwemishini nokwenziwa.

4. Ukusebenza kahle kwe-thiazenon kugcinwa isikhathi eside, futhi amaqabunga azowa esimweni esiluhlaza, okuxazulula ngokuphelele inkinga "yokomisa kodwa engawi", kunciphisa ukungcola kwamaqabunga ekuqoqweni kokotini komshini, futhi kuthuthukise ikhwalithi kanye nokusebenza kahle komsebenzi wokuqoqa ukotini ngomshini.

5, i-thiaphenone inganciphisa nokulimala kwezinambuzane esikhathini esizayo.

Isicelo

Izindaba ezidinga ukunakwa

1. Isikhathi sokufaka isicelo akufanele sibe sekuseni kakhulu, kungenjalo sizothinta isivuno.

2. Imvula zingakapheli izinsuku ezimbili ngemuva kokufaka izothinta ukusebenza kahle. Naka ukuvimbela isimo sezulu ngaphambi kokufaka.

3. Ungangcolisi ezinye izitshalo ukuze ugweme ukulimala kwezidakamizwa.
