IHormone yeZityalo eSebenza ngokukhawuleza edumileyo iThidiazuron 50% Sc CAS No. 51707-55-2

a. Lawula ukukhula kwaye wandise isivuno
Kwinqanaba lokuhluma kunye nenqanaba lokudubula kwerayisi, i-3 mg/L ye-thiazenon spray kanye kumphezulu ngamnye wegqabi inokuphucula umgangatho weempawu zerayisi zezolimo, yonyuse inani leenkozo nge-spike nganye kunye nesantya sokumiselwa kwembewu, yehlise inani leenkozo nge-spike nganye, kwaye yonyuse isivuno esiphezulu nge-15.9%.
Iidiliya zitshizwe nge-4~6 mg ye-L thiabenolon malunga neentsuku ezi-5 emva kokuba iintyatyambo ziwile, kwaye okwesibini kwisithuba seentsuku ezili-10 kunokukhuthaza ukuvela kweziqhamo nokudumba kwaye kwandise isivuno.
Ii-apile ezisembindini womthi we-apile zidubula i-10% ukuya kwi-20% kwaye ixesha lokudubula liphelele, kunye ne-2 ukuya kwi-4 mg/L yeyeza le-thiabenolon elisetyenziswa kanye, linokukhuthaza ukuvela kweziqhamo.
Usuku olu-1 okanye ngosuku olungaphambi kokuba kuvele iintyatyambo, i-4 ~ 6 mg/L yethiabenolon yasetyenziswa ukumanzisa i-embryo ye-melon kube kanye, nto leyo eyayinokukhuthaza ukwanda kwesivuno kwaye inyuse izinga le-sitting melon.

Isitshizi setamatato esingu-1 mg/L kanye ngaphambi kokuba sidubule kwaye xa sisesitsha, sinokukhuthaza ukukhula kwesiqhamo kwaye sonyuse isivuno kunye nengeniso.
Ukumanzisa i-cucumber embryo ene-4~ 5 mg/L ye-thiabenolon kanye ngaphambi kokuba idubule okanye ngaloo mini inye kunokukhuthaza ukubekwa kwesiqhamo kwaye konyuse ubunzima besiqhamo esinye.
Emva kokuvuna iseleri, ukutshiza isityalo sonke nge-1-10 mg/L kunokulibazisa ukonakala kwe-chlorophyll kwaye kukhuthaze ukugcinwa kohlaza.
Ubunzima besiqhamo esinye kunye nemveliso yejujube yanda xa i-0.15 mg/L yethiaphenone kunye ne-10 mg/L yegibberellic acid zisetyenziswa ekudubuleni kwangethuba, ekuwisweni kweziqhamo zemvelo kunye nokukhula kweziqhamo eziselula.
b. Ii-Defoliants
Xa ipesika yomqhaphu iqhekeka ngaphezu kwama-60%, i-10 ~ 20 g/mu ye-tiphenuron itshizwa ngokulinganayo kumagqabi emva kokuba amanzi ewafakile, nto leyo enokubangela ukuba amagqabi aqhekeke.

Ukuthelekiswa kweenzuzo kunye nokungalungi kwe-thiaphenone kunyei-ethephonndedwa:

I-Ethephon: Isiphumo sokuvuthwa kwe-ethephon singcono, kodwa isiphumo sokususwa kwamaqabunga asisihle! Xa isetyenziswa kumqhaphu, ingaqhekeza ngokukhawuleza ipesika yomqhaphu ize yomise amagqabi, kodwa kukwakho neengenelo ezininzi kunye nokungalungi kwe-ethylene:

1, isiphumo sokuvuthwa kwe-ethephon silungile, kodwa isiphumo sokukhuhla amahlamvu asisihle, senza amagqabi akheke “omile ngaphandle kokuwa”, ingakumbi xa ukusetyenziswa kokuvuna ngoomatshini ungcoliseko lomqhaphu kuyingozi kakhulu.

2, ngexesha elinye lokuvuthwa, isityalo sekotoni naso salahlekelwa ngamanzi ngokukhawuleza saza safa, kwaye amaxolo amancinci angaphezulu komqhaphu nawo afa, kwaye imveliso yomqhaphu yayinzima ngakumbi.

3, ukubethela umqhaphu akulunganga, ukuqhekeka kwepesika yomqhaphu kulula ukwenza iqokobhe, kunciphisa ukusebenza kakuhle kokuvuna, ingakumbi xa kuvunwa ngoomatshini, kulula ukuvuna kungacocekanga, ukwakheka kokuvuna okwesibini, kunyusa iindleko zokuvuna.

4, i-ethephon iya kuchaphazela nobude befayibha yomqhaphu, inciphise iintlobo zekhotoni, kube lula ukwenza umqhaphu ofileyo.

I-Thiabenolon: isiphumo sokususwa kwegqabi le-thiabenolon sibalasele kakhulu, isiphumo sokuvuthwa asilunganga njenge-ethephon, kuxhomekeke kwiimeko zemozulu (kukho abavelisi ngabanye abaneteknoloji yemveliso engcono, ukuveliswa kwezongezo ezisebenzayo ze-thiabenolon, kunokunciphisa kakhulu imida yemozulu ye-thiabenolon), kodwa ukusetyenziswa ngokufanelekileyo kuya kudlala indima entle:

1, emva kokusetyenziswa kwe-thiaphenone, ingenza isityalo sekotoni ngokwaso sivelise i-abscisic acid kunye ne-ethylene, nto leyo ebangela ukwakheka komaleko owahlukileyo phakathi kwe-petiole kunye nesityalo sekotoni, ukuze amagqabi ekotoni awe ngokwawo.

2. I-Thiaphenone inokudlulisa izondlo ngokukhawuleza kwiibholiti zekotoni eziselula ezikwinxalenye ephezulu yesityalo ngelixa amagqabi eseluhlaza, kwaye isityalo sekotoni asiyi kufa, sifikelele ekuvuthweni, ekususweni kwamagqabi, ekunyukeni kwesivuno, ekuphuculeni umgangatho kunye nokudibanisa iziphumo ezininzi.

3, i-thiabenolon ingenza umqhaphu kwangethuba, i-cotton boll ibetha kwangethuba, ixinene, inyuse umlinganiselo womqhaphu ngaphambi kokuba iqabaka. Umqhaphu awunqumli iqokobhe, awuwisi uboya, awuwisi intyatyambo, unyusa ubude befayibha, uphucula iqhezu lengubo, ulungele ukuvunwa ngoomatshini nangokwenziwa.

4. Ukusebenza kakuhle kwe-thiazenon kugcinwa ixesha elide, kwaye amagqabi aya kuwa xa eluhlaza, esombulula ngokupheleleyo ingxaki "yokomisa kodwa engawi", kunciphisa ungcoliseko lwamagqabi xa evunwa umqhaphu ngomatshini, kwaye kuphuculwe umgangatho kunye nokusebenza kakuhle komsebenzi wokuvuna umqhaphu ngoomatshini.

5, i-thiaphenone inokunciphisa nomonakalo wezinambuzane kwixesha elizayo.

Isicelo

Imiba efuna ingqwalasela

1. Ixesha lokufaka isicelo akufuneki libe sekuqaleni kakhulu, kungenjalo liya kuchaphazela isivuno.

2. Imvula zingadlulanga iintsuku ezimbini emva kokufaka iya kuchaphazela ukusebenza kwayo. Nika ingqalelo ekuthinteleni imozulu ngaphambi kokufaka.

3. Musa ukungcolisa ezinye izityalo ukuze ungalimazi iziyobisi.
