Prohexadione calcium inodzora kukura kwechirimwa inonyatso kusimudzira kukura kwemachubhu muzvirimwa zvakaita sembatatisi uye mbatatisi, kuvandudza goho uye kunaka.
Mechanism of Action: Nekudzivisa gibberellin synthesis, Prohexadione calcium inoputsa hutongi hweapical, zvichikonzera madzinde akakora uye mapfupi internodes, nokudaro kuderedza kukura kwezvinomera uye kunangidzira zvigadzirwa zvephotosynthetic kumachubhu. Panguva imwe cheteyo, inowedzera chlorophyll yemukati, inosimudzira photosynthetic kunyatsoita, uye inosimudzira kutamiswa kweasitimilate kune machubhu, ichiwedzera kuunganidzwa kwezvinhu zvakaoma.
Mhedzisiro yeProhexadione calcium application:
Inosimudzira kuwedzera tuber: Mushure mekushandisa, tuber kukwidziridzwa kunokurumidza, zvichikonzera kukura kwakafanana uye kuwedzera zvakanyanya goho.
Inovandudza mhando: Yakawedzera yakaoma nyaya yemukati uye yakagadziridzwa kuchengetedza hupenyu hwemachubhu inobatsira kune yakakwira kukosha kwemusika.
Inokwidziridza kusagadzikana kwekusagadzikana: Prohexadione calcium inosimudzirawo kukura kwemidzi, inodzivirira kumera nguva isati yakwana, uye ine imwe kudzora mhedzisiro pane zvimwe zvirwere (senge mbatata inononoka blight).
Maitiro ekushandisa Prohexadione calcium:
Kugadzira uye kuyerwa: Prohexadione calcium inowanzowanikwa se5% effervescent granule kana wettable powder. Kune mbatatisi uye mbatatisi, zvinokurudzirwa kushandisa 20-40 magiramu e5% Prohexadione calcium per mu (inenge 0.067 hectares), inoshandiswa 1-2 nguva zvichienderana nemamiriro ekukura.
Nguva yekushandiswa yakakosha: Kunyorera kunofanirwa kutanga kubva padanho rekutanga rekugadzira tuber kusvika pakutanga kwedanho rekuwedzera tuber, apo chirimwa chiri kuratidza kukura kwakasimba, kuitira mhedzisiro yakakwana.
Chengetedzo: Dzivisa kushandiswa pasi pemamiriro ane acidic yakasimba. Inogona kusanganiswa nemamwe mafetireza kana zvigadziriso (senge DA-6) kuti iwedzere mhedzisiro, asi kutarisisa kunofanirwa kubhadharwa kune iyo yekumisikidza kudzivirira zvakanyanya kukura inhibition.
