Feteleza Wokonza Wachikasu

(1)Matenda achikasu amatanthauza kupendekeka kwa gawo kapena masamba onse a mmera, zomwe zimapangitsa kukhala chikasu kapena kubiriwira kwachikasu. Yellowing matenda akhoza kugawidwa m'magulu awiri: zokhudza thupi ndi pathological. Physiological yellowness nthawi zambiri imayamba chifukwa cha kusayenda bwino kwa chilengedwe (chilala, kutsika kwamadzi kapena nthaka yopanda pake) kapena kusowa kwa michere ya zomera.

(3) Chogulitsachi ndi feteleza wopatsa thanzi omwe amapangidwira matenda amtundu wa yellowing. Kupukuta kapena kupopera mbewu mankhwalawa kumatha kusintha chilengedwe cha mizu kapena masamba. Malo a acidic pang'ono amathandizira kuyamwa ndi kugwiritsa ntchito zinthu zapakatikati ndi zowunikira. Shuga alcohols kwathunthu chelate kufufuza zinthu.
(4) Chakudyacho chimatha kutengedwa mwachangu mkati mwa phloem ya mbewu ndikuyamwa mwachindunji ndikugwiritsidwa ntchito ndi magawo ofunikira. Izi sizingafanane ndi feteleza wamba wa trace element.
(5) Izi ndizokwanira pazowonjezera zake zopatsa thanzi ndipo zimatha kuwonjezera michere yosiyanasiyana yomwe ilibe matenda achikasu achilengedwe ndi kutsitsi kumodzi. Ili ndi ubwino wopulumutsa nthawi, zovuta, zolondola komanso zogwira mtima.
