Ukusebenza Okusheshayo Okudumile Ukusetshenziswa Kwe-Hormone Yesitshalo Thidiazuron 50% Sc CAS No. 51707-55-2

a. Lawula ukukhula futhi andise isivuno
Esigabeni sokutshala kanye nesigaba sokuqhakaza kwerayisi, isifutho se-thiazenon esingu-3 mg/L kanye endaweni ngayinye yeqabunga singathuthukisa ikhwalithi ye-agronomic yerayisi, kukhuphule inani lokusanhlamvu ngesipikili ngasinye kanye nezinga lokubeka imbewu, kunciphise inani lokusanhlamvu ngesipikili ngasinye, futhi ukwandisa isivuno esiphezulu ngo-15.9%.
Amagilebhisi afuthwe nge-4 ~ 6 mg ye-L thiabenolon cishe ezinsukwini ezi-5 ngemuva kokuwa kwezimbali, futhi okwesibili ngesikhathi sezinsuku ezingu-10 kungakhuthaza ukumiswa kwezithelo nokuvuvukala nokwandisa isivuno.
Ama-apula aphakathi kwesihlahla se-apula aqhakaza u-10% kuya ku-20% futhi isikhathi sokuqhakaza esigcwele, kanye no-2 kuya ku-4 mg/L womuthi we-thiabenolon osetshenziswe kanye, angakhuthaza ukumiswa kwezithelo.
Usuku olungu-1 noma ngosuku olwandulela ukuqhakaza, i-4 ~ 6 mg/L i-thiabenolon yayisetshenziselwa ukucwilisa umbungu we-melon kanye, okungase kukhuthaze ukwanda kwesivuno futhi kwandise izinga lokuhlala kwekhabe.

Fafaza utamatisi ngo-1 mg/L womuthi owuketshezi kanye ngaphambi kokuqhakaza kanye nasesiteji sezithelo ezincane kungakhuthaza ukukhula kwesithelo futhi kwandise isivuno nemali engenayo.
Ukucwilisa umbungu wekhukhamba ngo-4 ~ 5 mg/L we-thiabenolon kanye ngaphambi kokuqhakaza noma ngosuku olufanayo kungakhuthaza ukuhlelwa kwesithelo futhi kwandise isisindo sesithelo esisodwa.
Ngemuva kokuvuna isilimo esidliwayo esinamagatsha anamanzi, ukufafaza isitshalo sonke ngo-1-10 mg/L kungabambezela ukuwohloka kwe-chlorophyll futhi kukhuthaze ukulondolozwa kohlaza.
Isisindo sesithelo esisodwa kanye nesivuno se-jujube sikhuphuke lapho u-0.15 mg/L we-thiaphenone kanye no-10 mg/L we-gibberellic acid esetshenziswa ekuqaleni kwezimbali, ukuwa kwezithelo zemvelo kanye nokwanda kwezithelo ezincane.
b. Ama-Defoliants
Lapho ipentshisi likakotini liqhekeka ngaphezu kuka-60%, i-10 ~ 20 g/mu ye-tiphenuron ifafazwa ngokulinganayo emaqabunga ngemva kwamanzi, okungakhuthaza ukuchithwa kwamaqabunga.

Ukuqhathaniswa kwezinzuzo kanye nokubi kwe-thiaphenone kanyei-ethephonyedwa:

I-Ethephon: Umphumela wokuvuthwa we-ethephon ungcono, kodwa umphumela wokubola mubi! Uma isetshenziswa ukotini, ingaqhekeka ngokushesha ipentshisi likakotini futhi yomise amaqabunga, kodwa futhi kunezinzuzo eziningi kanye nokubi kwe-ethylene:

I-1, umphumela wokuvuthwa we-ethephon muhle, kodwa umphumela we-defoliation mubi, wenza amaqabunga abe "omile ngaphandle kokuwa", ikakhulukazi uma ukusetshenziswa kokuvuna ngomshini kokungcoliswa kukakotini kubi kakhulu.

2, ngesikhathi esifanayo sokuvuthwa, isitshalo sikakotini salahlekelwa amanzi ngokushesha futhi safa, futhi amabhodlela amancane phezulu ukotini nawo afa, futhi ukukhiqizwa kukakotini kwakubi kakhulu.

3, ukotini batting akukuhle, ukotini peach ukuqhekeka kulula ukwakha igobolondo, ukunciphisa ukusebenza kahle kokuvuna, ikakhulukazi lapho ukuvuna mechanical, kulula ukuvuna ezingcolile, ukwakheka kokuvuna yesibili, ukwandisa izindleko zokuvuna.

I-4, i-ethephon izophinde ithinte ubude be-cotton fiber, inciphise izinhlobo zikakotini, kulula ukwenza ukotini ofile.

I-Thiabenolon: umphumela wokususwa kweqabunga le-thiabenolon muhle kakhulu, umphumela wokuvuthwa awulungile njenge-ethephon, ngaphansi kwezimo zezulu (kunabakhiqizi ngabanye abanobuchwepheshe obungcono bokukhiqiza, ukukhiqizwa kwezithasiselo ezisebenzayo ze-thiabenolon, kunganciphisa kakhulu izingqinamba zesimo sezulu se-thiabenolon), kodwa ukusetshenziswa okunengqondo kuzoba nomphumela omuhle:

I-1, ngemva kokusetshenziswa kwe-thiaphenone, ingenza isitshalo sikakotini ngokwaso sikhiqize i-abscisic acid ne-ethylene, okuholela ekwakhekeni kwesendlalelo esihlukile phakathi kwe-petiole nesitshalo sikakotini, ukuze amaqabunga kakotini awele ngokwawo.

2. I-Thiaphenone ingadlulisela ngokushesha umsoco kumabholl kakotini amancane engxenyeni engenhla yesitshalo ngenkathi amaqabunga esaluhlaza, futhi isitshalo sikakotini ngeke sife, sifeze ukuvuthwa, ukubola, ukukhuphuka kwesivuno, ukuthuthukiswa kwekhwalithi kanye nenhlanganisela yemiphumela eminingi.

3, i-thiabenolon ingenza ukotini kusenesikhathi, ibholi yekotini ishaye kusenesikhathi, igxile, ikhulise ingxenye kakotini ngaphambi kwesithwathwa. Ukotini awulinqumi igobolondo, awuliwisi i-wadding, awuwehli imbali, ukhulisa ubude be-fiber, uthuthukisa ingxenyena yengubo, uvumela ukuvunwa ngomshini nangokwenziwa.

4. Ukusebenza kwe-thiazenon kugcinwa isikhathi eside, futhi amaqabunga azowela esimweni esiluhlaza, axazulule ngokuphelele inkinga "yokoma kodwa engawi", ukunciphisa ukungcoliswa kwamaqabunga emshinini wokukha ukotini, nokwenza ngcono. ikhwalithi nokusebenza kahle komsebenzi wokukha ukotini ngemishini.

5, i-thiaphenone nayo inganciphisa ukulimala kwezinambuzane esikhathini esizayo.

Isicelo

Izindaba ezidinga ukunakwa

1. Isikhathi sokufaka isicelo akumele sibe ngaphambi kwesikhathi, ngaphandle kwalokho sizoba nomthelela emvuzweni.

2. Imvula phakathi kwezinsuku ezimbili ngemuva kokufakwa kwesicelo izothinta ukusebenza kahle. Naka ukuvimbela isimo sezulu ngaphambi kokufaka isicelo.

3. Ungangcolisi ezinye izitshalo ukuze ugweme ukulimala kwezidakamizwa.
