Ntchito mbewu ndi zotsatira za paclobutrazol
1. Mbewu zogwiritsidwa ntchito za paclobutrazol:
Mbewu za m’munda ndi monga tirigu, chimanga, mpunga, ndi zina zotero;
Mbewu za ndalama ndi monga soya, rapeseed, mtedza, thonje, mbatata, radishes, fodya, etc.;
Zipatso zikuphatikizapo maapulo, mapeyala, mapichesi, hawthorns, yamatcheri, pomelo ya uchi, litchi, etc.;
Maluwa ndi oyeneranso paclobutrazol.
2. Mfundo yothandiza ya paclobutrazol:
Paclobutrazol ndi ntchito yaulimi yomwe imatha kufooketsa mwayi wakukula kwa zomera. Imatha kuyamwa ndi mizu ya mbewu ndi masamba, kuwongolera kagawidwe ka michere ya mbewu, kuchepetsa kakulidwe kake, kulepheretsa kukula kwa nsonga ndi kutalika kwa tsinde, ndikufupikitsa mtunda wa internode. Panthawi imodzimodziyo, imalimbikitsa kusiyanitsa kwa maluwa, kumawonjezera kuchuluka kwa maluwa, kumawonjezera kuchuluka kwa zipatso, kumathandizira kugawanika kwa maselo, kumawonjezera chlorophyll, kumalimbikitsa kubzala, kumalimbitsa mizu, komanso kumawonjezera kukana kwa zomera. Kuchepa kwa paclobutrazol kungapangitse photosynthesis ya masamba ndikulimbikitsa kukula, pamene kukwera kwakukulu kungathe kulepheretsa photosynthesis, kulimbitsa kupuma kwa mizu, ndi kuchepetsa kukula kwa tsinde ndi masamba. Kuphatikiza apo, paclobutrazol imathanso kukulitsa zokolola za zipatso ndi zabwino, ndipo imatha kupha mabakiteriya ndikuletsa kukula kwa udzu.
3. Njira zopewera kugwiritsa ntchito paclobutrazol:
1. Mitundu yosiyanasiyana ya nyengo ndi mitundu ya mbewu imakhala ndi zofunikira zosiyanasiyana za ndende ndi mlingo, chifukwa chake muyenera kukhala osinthika mukamagwiritsa ntchito.
2. Tsatirani mosamalitsa malangizo ogwiritsira ntchito kuti mupewe kugwiritsa ntchito kwambiri komanso kuwononga mankhwala.
3. Ngati kugwiritsa ntchito mopitirira muyeso kumapangitsa kuti mbeu isakule bwino, iyenera kukonzedwanso munthawi yake powonjezera feteleza wa nayitrogeni kapena kupopera mbewu mankhwalawa gibberellin.
