6-Benzylaminopurine (6-BA) yog ib qho khoom siv cytokinin uas txhawb nqa kev faib tawm ntawm tes, ua rau lub paj sib txawv, thiab qeeb senescence, ua rau nws tsim nyog rau kev tswj hwm pob paj hauv paj shaping.
Kev Siv: 6-BA feem ntau yog siv hauv cov hmoov soluble. Nws yuav tsum xub yaj nyob rau hauv ib tug me me ntawm dilute acid (xws li 0.1 mol / L hydrochloric acid), ces diluted nrog dej mus rau qhov xav tau concentration. Rau kev txhawb nqa kev loj hlob hauv paj, qhov pom zoo ntau yam yog 10-50 mg/L, sib txawv nyob ntawm seb hom paj. Piv txwv li, Roses tuaj yeem kho nrog 2% formulation diluted 200 zaug (kwv yees li 50 mg/L) los ntawm soaking noob los yog tshuaj tsuag. Azaleas tuaj yeem txau nrog 40-80 zaug dilution (kwv yees li 25-50 mg/L) thaum lub caij cog qoob loo los txhawb kev loj hlob ntawm nplooj. Thaum txau, buds lossis cov ntsiab lus loj hlob yuav tsum tau muab sib npaug, tsis txhob muaj lub sijhawm kub kub; Nws raug nquahu kom txau thaum sawv ntxov lossis yav tsaus ntuj. Daim ntawv thov cuam tshuam: 6-BA muaj txiaj ntsig zoo tawg paj dormancy, induces paj bud sib txawv, thiab tsub kom tus naj npawb ntawm lateral buds, yog li txhim kho cog compactness thiab flowering ntim. Piv txwv li, nws daim ntawv thov rau cov nroj tsuag xws li txiv apples thiab roses tuaj yeem txhawb cov ceg ntoo sprouting, uas yog qhov zoo rau shaping thiab pruning. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias kev siv ntau dhau yuav ua rau muaj kev loj hlob ntau dhau lossis deformities. Nws raug nquahu kom ua qhov kev sim me me ua ntej siv thawj zaug.
Kev ceev faj: 6-BA muaj kev txav qeeb hauv cov nroj tsuag thiab yuav tsum tau txau ncaj qha rau ntawm qhov chaw thov. Kev sib xyaw nrog lwm cov kev tswj hwm xws li gibberellin (piv txwv li, 100 mg/L 6-BA ntxiv rau 100 mg/L GA3) tuaj yeem txhim kho cov paj-txhim kho cov nyhuv. Khaws rau hauv qhov chaw txias, qhuav, tsis txhob tshav ntuj ncaj qha.
