Kashiamu ya Prohexadione ndiyomwe imathandizira kukula kwa mbewu zomwe zimalimbikitsa kukula kwa ma tubers mu mbewu monga mbatata ndi mbatata, kukulitsa zokolola ndi zabwino.
Kachitidwe kake: Poletsa kaphatikizidwe ka gibberellin, kashiamu ya Prohexadione imaphwanya mphamvu ya apical, zomwe zimapangitsa kuti zimayambira zokhuthala komanso ma internodes azifupi, motero amachepetsa kukula kwa zomera ndikulondolera zinthu za photosynthetic ku ma tubers. Panthawi imodzimodziyo, imawonjezera chlorophyll, imapangitsa kuti photosynthetic igwire bwino, ndipo imalimbikitsa kusuntha kwa assimilates ku tubers, ndikuwonjezera kuuma kwa zinthu.
Zotsatira za Prohexadione calcium application:
Imalimbikitsa kukula kwa tuber: Pambuyo pa ntchito, kukulitsa kwa tuber kumafulumizitsa, zomwe zimapangitsa kuti kukula kwake kukhale kofanana komanso kuchulukitsa kwambiri zokolola.
Kupititsa patsogolo ubwino: Kuchulukitsa kwa zinthu zowuma komanso moyo wosungika bwino wa ma tubers kumathandizira kuti pakhale mtengo wamsika.
Imakulitsa kukana kupsinjika: Prohexadione calcium imalimbikitsanso kukula kwa mizu, imateteza kubadwa msanga, ndipo imakhala ndi mphamvu yowononga matenda ena (monga kuchedwa kwa mbatata).
Momwe mungagwiritsire ntchito Prohexadione calcium:
Kupanga ndi mlingo: Prohexadione calcium imapezeka kawirikawiri ngati 5% effervescent granule kapena ufa wonyowa. Kwa mbatata ndi mbatata, tikulimbikitsidwa kugwiritsa ntchito 20-40 magalamu a 5% Prohexadione calcium pa mu (pafupifupi mahekitala 0.067), ogwiritsidwa ntchito 1-2 kutengera kukula.
Nthawi yofunika kwambiri yobzala tuber: Kubzala kuyenera kuyambika kuyambira pomwe tuber imapangidwira mpaka pomwe tuber ikukula, pomwe mbewuyo ikuwonetsa kukula mwamphamvu, kuti zotsatira zake zikhale zabwino.
Chenjerani: Pewani kugwiritsa ntchito zinthu za acidic kwambiri. Itha kusakanikirana ndi feteleza ena kapena zowongolera (monga DA-6) kuti ziwonjezeke, koma chidwi chiyenera kuperekedwa ku ndende kuti tipewe kuletsa kukula kwakukulu.
