Umlawuli woKhuliso lweZityalo zoMzi-mveliso iPaclobutrazol CAS 76738-62-0 uyathengiswa

Ingcaciso yeMveliso

I-Paclobutrazol (PBZ) yi-antioxidant enamandla.Umlawuli woKhula kweZityalokunye ne-triazole Fungicide. Yinto eyaziwayo ukuba ichasene ne-ihomoni yezityaloIsebenza ngokuthintela i-gibberellin biosynthesis, inciphisa ukukhula kwangaphakathi kwama-nodial ukuze inike iziqu eziqinileyo, inyuse ukukhula kweengcambu, ibangele ukuvela kweziqhamo kwangethuba kwaye inyuse ukuvela kwembewu kwizityalo ezifana netamatato nepepile.

Ukusetyenziswa

1. Ukuhlwayela izithole ezomeleleyo kwirayisi: Ixesha elifanelekileyo lonyango ngerayisi ligqabi elinye, ixesha lentliziyo enye, elithatha iintsuku ezi-5-7 emva kokuhlwayela. Umlinganiselo ofanelekileyo we-15% paclobutrazol powder emanzi yi-3 kg kwihektare nganye kunye ne-1500 kg yamanzi eyongeziweyo (oko kukuthi, i-200 grams ye-paclobutrazol kwihektare nganye kunye ne-100 khilogrem yamanzi eyongeziweyo). Amanzi akwintsimi yezithole ayomile, kwaye izithole zitshizwa ngokulinganayo. Uxinzelelo lwe-15% paclobutrazol luphindwe ka-500 kulwelo (300ppm). Emva konyango, izinga lokwandiswa kwesityalo liyehla, lifezekisa iziphumo zokulawula ukukhula, ukukhuthaza ukuhluma, ukuthintela ukungaphumeleli kwezithole, kunye nokuqinisa izithole.

2. Lima izithole ezomeleleyo kwinqanaba lamagqabi amathathu ezithole ze-rape, sebenzisa i-600-1200g ye-15% ye-paclobutrazol powder emanzi kwihektare nganye, kwaye wongeze i-900kg yamanzi (100-200Chemicalbookppm) ukutshiza iziqu kunye namagqabi ezithole ze-rape, ukukhuthaza ukwenziwa kwe-chlorophyll, ukuphucula izinga le-photosynthesis, ukunciphisa isifo se-sclerotinia, ukonyusa ukumelana, ukwandisa ii-pods kunye nesivuno.

3. Ukuthintela ukuba iimbotyi zesoya zingakhuli ngokukhawuleza kunesigaba sokuqala sokudubula, iigram ezingama-600-1200 ze-15% ye-paclobutrazol powder emanzi kwihektare nganye, i-900 kg yamanzi (100-200 ppm), kunye nolwelo olutshizayo kwisiqu kunye negqabi lezityalo zesoya ukulawula ubude, ukwandisa iipods kunye nesivuno.

4. Ulawulo lokukhula kwengqolowa kunye nokugquma imbewu ngobunzulu obufanelekileyo be-paclobutrazol kunezithombo ezinamandla, ukwanda kokuhluma, ukuphakama okunciphileyo, kunye nefuthe elikhulayo lesivuno kwingqolowa. Xuba iigram ezingama-20 ze-15% ye-paclobutrazol emanzi kunye neekhilogram ezingama-50 zembewu yengqolowa (oko kukuthi i-60ppm), kunye nesantya sokunciphisa ukuphakama kwesityalo esimalunga ne-5% kwiChemicalbook. Ifanelekile kumasimi engqolowa okuhlwayelwa kwangethuba anobunzulu obuziisentimitha ezi-2-3, kwaye kufuneka isetyenziswe xa umgangatho wembewu, ukulungiswa komhlaba, kunye nomxholo wokufuma kulungile. Okwangoku, ukuhlwayelwa komatshini kusetyenziswa kakhulu kwimveliso, kwaye kunokuchaphazela izinga lokuvela xa ubunzulu bokuhlwayela kunzima ukulawula, ngoko ke akufanelekanga ukuyisebenzisa.
