IFactory Supply Plant Regulator Paclobutrazol CAS 76738-62-0 iyathengiswa

Ingcaciso yeMveliso

I-Paclobutrazol (PBZ) iUMlawuli wokuKhula kweZityalokunye ne-triazole Fungicide. Ngumchasi owaziwayo weihomoni yezityalogibberellin. Isebenza ngokunqanda i-gibberellin biosynthesis, inciphisa ukukhula kwe-internodial ukunika iziqu, ukwandisa ukukhula kweengcambu, kubangela i-fruitet yokuqala kunye nokwandisa imbewu kwizityalo ezifana netumata kunye nepepile.

Ukusetyenziswa

1. Ukuhlakulela izithole ezinamandla kwirayisi: Elona xesha lamayeza erayisi ligqabi elinye, ixesha lentliziyo enye, eliziintsuku ezi-5-7 emva kokuhlwayela. Umlinganiselo ofanelekileyo we-15% we-paclobutrazol powder wettable yi-3 kilograms ngehektare nganye kunye ne-1500 yeekhilogram zamanzi ezongeziweyo (oko kukuthi i-200 grams ye-paclobutrazol ngehektare kunye ne-100 kilograms yamanzi eyongeziweyo). Amanzi kwintsimi yezithole omisiwe, kwaye izithole zitshizwa ngokulinganayo. Uxinzelelo lwe-15% paclobutrazol ngamaxesha angama-500 ulwelo (300ppm). Emva kokunyangwa, isantya sokwandisa isityalo siyacotha, ukufezekisa iziphumo zokulawula ukukhula, ukukhuthaza ukulima, ukuthintela ukusilela kwezithole, kunye nokomeleza izithole.

2. Lima izithole ezomeleleyo kwinqanaba lamagqabi amathathu odlwengulo, sebenzisa i-600-1200g ye-15% ye-paclobutrazol engumgubo omanzi ngehektare, kwaye wongeze i-900kg yamanzi (100-200Chemicalbookppm) ukutshiza iziqu kunye namagqabi e-rape seedlings, ukuphucula i-rape seedlings, ukuphucula i-rape seedlings. sclerotinia isifo, ukomeleza ukumelana, ukwandisa imidumba kunye nesivuno.

3. Ukuthintela ukuba imbotyi yesoya ingakhuli ngokukhawuleza kunenqanaba lokuqala lokudumba, i-600-1200 grams ye-15% ye-paclobutrazol engumgubo omanzi ngehektare nganye, i-900 kg yamanzi (100-200 ppm), kunye nolwelo lokutshiza isiqu negqabi lezithole zesoya ukulawula ubude, isivuno sembewu.

4. Ukulawulwa kokukhula kwengqolowa kunye nokufakwa kwembewu ngobunzulu obufanelekileyo be-paclobutrazol ineedling eyomeleleyo, i-tillering eyandisiweyo, ubude obuncitshisiweyo, kunye nokwanda kwefuthe lesivuno kwingqolowa. Xuba i-20 grams ye-15% ye-paclobutrazol yomgubo omanzi kunye neekhilogram ezingama-50 zembewu yengqolowa (okt 60ppm), kunye neqondo lokunciphisa ubude besityalo malunga ne-5% kwi-Chemicalbook. Ilungele ukutyalwa kwangethuba amasimi engqolowa anobunzulu obuyi 2-3 centimeters, kwaye kufuneka isetyenziswe xa umgangatho wembewu, ukulungiswa komhlaba, kunye nesiqulatho sokufuma silungile. Okwangoku, ukuhlwayelwa komatshini kusetyenziswa ngokubanzi kwimveliso, kwaye kunokuchaphazela izinga lokuvela xa ubunzulu bokuhlwayela kunzima ukulawula, ngoko akufanelekanga ukuyisebenzisa.
