I-CAS 76738-62-0 iziLawuli zokuKhula kweZityalo iPaclobutrazol

I-Paclobutrazol yeye-azoleisityaloIziLawuli zokuKhula.Luhlobo lwe-biosynthetic inhibitors ye-gibberellin engapheliyo.Ineziphumo zokuthintelaukukhula kwesityalokunye nokunciphisa inowuthi.Isetyenziselwa irayisi ekuphuculeni umsebenzi we-indoleIAcetic Acidi-oxidase, ukunciphisa inqanaba le-IAA engapheliyo kwizithole zerayisi, ukulawula ngokuphawulekayo izinga lokukhula komphezulu wezithole zerayisi, ukukhuthaza iqabunga, ukwenza amaqabunga amnyama aluhlaza, inkqubo yeengcambu iphuhliswe, ukunciphisa indawo yokulala kunye nokwandisa inani lemveliso.

Ukusetyenziswa

1. Ukuhlakulela izithole ezinamandla kwirayisi: Elona xesha lamayeza erayisi ligqabi elinye, ixesha lentliziyo enye, eliziintsuku ezi-5-7 emva kokuhlwayela.Umthamo ofanelekileyo wokusetyenziswa ngu-15% we-paclobutrazol powder wettable, kunye neekhilogram ezi-3 ngehektare nganye kunye ne-1500 yeekhilogram zamanzi zongezwa.

Ukuthintela irayisi yokulala: Ngexesha lokudibanisa irayisi (iintsuku ezingama-30 ngaphambi kokuhamba), sebenzisa i-1.8 kilogram ye-15% ye-paclobutrazol powder emanzi ngehektare kunye ne-900 yeekhilogram zamanzi.

2. Hlakula izithole ezomeleleyo zerapeseed ngexesha lamagqabi amathathu, usebenzisa i-600-1200 grams ye-15% ye-paclobutrazol engumgubo omanzi ngehektare kunye ne-900 yeekhilogram zamanzi.

3. Ukuthintela iimbotyi zesoya ekukhuleni ngokugqithiseleyo ngexesha lokuqala kweentyantyambo, sebenzisa i-600-1200 grams ye-15% ye-paclobutrazol powder emanzi ngehektare kwaye ungeze iikhilogram ezingama-900 zamanzi.

4. Ukulawulwa kokukhula kwengqolowa kunye nokufakwa kwembewu ngobunzulu obufanelekileyo be-paclobutrazol ineedling eyomeleleyo, i-tillering eyandisiweyo, ubude obuncitshisiweyo, kunye nokwanda kwefuthe lesivuno kwingqolowa.

Ukuqwalaselwa

1. I-Paclobutrazol yi-inhibitor eqinile yokukhula kunye ne-half-life of 0.5-1.0 iminyaka emhlabeni phantsi kweemeko eziqhelekileyo, kunye nexesha elide lokuhlala.Emva kokutshiza kwintsimi okanye kwinqanaba lezityalo zemifuno, lihlala lichaphazela ukukhula kwezityalo ezilandelayo.

2. Lawula ngokungqongqo idosi yechiza.Nangona okukhona kuphezulu ukuxinana kwechiza, kokukhona ifuthe lokulawula ubude linamandla, kodwa ukukhula kuyancipha.Ukuba ukukhula kucotha emva kokulawula okugqithisileyo, kwaye umphumo wokulawula ubude awunakufezekiswa ngedosi ephantsi, umlinganiselo ofanelekileyo wokutshiza kufuneka usetyenziswe ngokulinganayo.

3. Ukulawulwa kobude kunye nokuhlakula kuncipha ngokunyuka kwexabiso lokuhlwayela, kwaye isixa sokuhlwayelwa kwe-hybrid rice kade ayidluli kwi-450 kilogram/hektare.Ukusebenzisa izixhobo zokuhlakula ukutshintsha izithole kusekelwe ekuhlwayeleni kancinci.Kuphephe ukukhukula kunye nokufakwa ngokugqithisileyo kwesichumiso senitrogen emva kokufakwa.

4. Ukukhula okukhuthaza umphumo we-paclobutrazol, i-gibberellin, kunye ne-indoleacetic acid inokuthintela ukuchasana nomphumo.Ukuba i-dosage iphezulu kakhulu kwaye izithole zithintelwe ngokugqithiseleyo, isichumisi se-nitrogen okanye i-gibberellin singongeza ukubahlangula.

5. Isiphumo esincinci se-paclobutrazol kwiindidi ezahlukeneyo zerayisi kunye nengqolowa ziyahluka.Xa uyisebenzisa, kuyimfuneko ukunyusa ngokuguquguqukayo okanye ukunciphisa umthamo ngokufanelekileyo, kwaye indlela yeyeza lomhlaba akufanele isetyenziswe.
