I-CAS 76738-62-0 Abalawuli boKhula kweZityalo iPaclobutrazol

I-Paclobutrazol ikwi-azoleisityaloAbalawuli bokukhula.Luhlobo lwe-biosynthetic inhibitors ye-endogenous gibberellin. Lunefuthe ekuthinteleniukukhula kwezityalokunye nokunciphisa iphimbo. Isetyenziswa kwirayisi ukuphucula umsebenzi we-indoleI-Acetic Acidi-oxidase, enciphisa inqanaba le-IAA yendalo kwizithole zerayisi, ilawula kakhulu izinga lokukhula kwephezulu kwezithole zerayisi, ikhuthaza amagqabi, yenza amagqabi abe luhlaza okwesibhakabhaka, inkqubo yeengcambu iphuhliswe, inciphisa indawo yokuhlala kwaye yonyusa ubungakanani bemveliso.

Ukusetyenziswa

1. Ukuhlwayela izithole ezomeleleyo kwirayisi: Ixesha elifanelekileyo lonyango kwirayisi ligqabi elinye, ixesha lentliziyo enye, elithatha iintsuku ezi-5-7 emva kokuhlwayela. Umlinganiselo ofanelekileyo wokusetyenziswa yi-15% ye-paclobutrazol powder emanzi, kunye neekhilogram ezi-3 kwihektare nganye kunye neekhilogram ezili-1500 zamanzi ezongeziweyo.

Ukuthintela ukuxinana kwerayisi: Ngexesha lokudibana kwerayisi (iintsuku ezingama-30 ngaphambi kokusebenzisa i-heading), sebenzisa iikhilogram ezili-1.8 ze-15% ye-paclobutrazol powder emanzi kwihektare nganye kunye neekhilogram ezingama-900 zamanzi.

2. Lima izithole ezomeleleyo zerapeseed ngexesha lesigaba samagqabi amathathu, usebenzisa iigram ezingama-600-1200 ze-15% ye-paclobutrazol powder emanzi kwihektare nganye kunye neekhilogram ezingama-900 zamanzi.

3. Ukuthintela iimbotyi zesoya ukuba zingakhuli kakhulu ngexesha lokuqala lokudubula, sebenzisa iigram ezingama-600-1200 ze-15% ye-paclobutrazol powder emanzi kwihektare nganye uze wongeze iikhilogram ezingama-900 zamanzi.

4. Ulawulo lokukhula kwengqolowa kunye nokufakelwa kwembewu ngobunzulu obufanelekileyo be-paclobutrazol kunezithole ezinamandla, ukwanda kokuhluma, ubude obuphantsi, kunye nefuthe elikhulayo lesivuno kwingqolowa.

Iingqalelo

1. I-Paclobutrazol sisithinteli sokukhula esinamandla esinobomi obuyisiqingatha seminyaka eyi-0.5-1.0 emhlabeni phantsi kweemeko eziqhelekileyo, kunye nexesha elide lomphumo oshiyekileyo. Emva kokutshiza emasimini okanye kwinqanaba lokuhluma kwezityalo zemifuno, kudla ngokuchaphazela ukukhula kwezityalo ezilandelayo.

2. Lawula ngokungqongqo umthamo weyeza. Nangona ubuninzi beyeza buphezulu, kokukhona isiphumo solawulo lobude siqina, kodwa ukukhula kuyancipha. Ukuba ukukhula kuhamba kancinci emva kolawulo olugqithisileyo, kwaye isiphumo solawulo lobude asinakufezekiswa ngedosi ephantsi, kufuneka kusetyenziswe isixa esifanelekileyo sesitshizi ngokulinganayo.

3. Ulawulo lobude kunye nokuhluma kwembewu kunciphisa xa kusanda inani lokuhlwayela, kwaye inani lokuhlwayela irayisi exutyiweyo emva kwexesha alidluli kwi-450 kg/hectare. Ukusebenzisa izihluma endaweni yezityalo kusekelwe ekuhlwayeleni okuncinci. Kuphephe ukugcwala kunye nokufaka isichumiso se-nitrogen kakhulu emva kokufaka.

4. Isiphumo sokukhuthaza ukukhula se-paclobutrazol, i-gibberellin, kunye ne-indoleacetic acid sinesiphumo sokuthintela ukuchasana. Ukuba idosi iphezulu kakhulu kwaye izithole zithintelwe kakhulu, isichumisi se-nitrogen okanye i-gibberellin singongezwa ukuzisindisa.

5. Isiphumo se-paclobutrazol esincinci kwiintlobo ezahlukeneyo zerayisi nengqolowa siyahluka. Xa uyisebenzisa, kuyimfuneko ukwandisa okanye ukunciphisa umthamo ngendlela eguquguqukayo, kwaye indlela yonyango lomhlaba akufuneki isetyenziswe.
