IHormone yePaclobutrazol yeZityalo zezoLimo zoLimo

"Paclobutrazol"(PBZ) yiUMlawuli wokuKhula kweZityalokunye ne-triazoleI-fungicide.Ngumchasi owaziwayo we-hormone yesityalo i-gibberellin.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%paclobutrazolngama-500 amaxesha olwelo (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 i600-1200g ye 15% paclobutrazol umgubo omanzi ngehektare nganye, kwaye ugalele i900kg yamanzi (100-200Chemicalbookppm) ukutshiza iziqu kunye namagqabi eedlelo chloroll, ukukhuthaza izithole. i-synthesis, ukuphucula izinga le-photosynthetic, ukunciphisa isifo se-sclerotinia, ukomeleza ukuxhathisa, 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 fafaza isiqu kunye negqabi lezithole zeembotyi zesoya. ukulawula ubude, ukwandisa imidumba kunye nesivuno.

4. Ulawulo lokukhula kwengqolowa kunye nokuthungwa kwembewu ngobunzulu obufanelekileyo"Paclobutrazol"ibenezithole ezomeleleyo, i-tillering eyongeziweyo, ubude obuncitshisiweyo, kunye nesiphumo sokwanda kwesivuno 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.
