Kumayambiriro kwa potaziyamu kuchepa,chomera cha udzuShow S onetsani kukula pang'ono ndi masamba obiriwira amdima. Makhalidwe Akuluakulu a kuchepa kwa potaziyamu: nthawi zambiri pamasamba akale ndi masamba a masamba amatembenukira chikasu poyamba, kenako ndikuwotcha, ndikuwotcha, mitsempha ndi madera okhala pafupi ndi mitsempha. Monga kuchuluka kwa kuchepa kwa potaziyamu kumawonjezeka, tsamba lonse limatembenuka bulauni kapena lowuma, necrotizs ndikugwa; Masamba ena azomera ndi amkuwa, amapindika pansi, ndikugunda minyewa ya mesophyll pamtunda wa tsamba komanso mitsempha. Zomera zikakhala po potaziyamu, mizu imawonongekanso kwambiri, ndi mizu yochepa komanso yovuta, imazungulira milandu, ndikugona pamizu yambiri. Zomera za udzu zikakhala po potaziyamu, mawanga bulauni amawoneka pa masamba otsika, komanso oopsa, zizindikiro zomwezo zimawonekera masamba atsopano. Masamba ndi ofewa komanso akugwedezeka, zimayambira ndi zopyapyala komanso zofooka, ndipo mafayilo ndi ochepa; Pamene mbewu zotsika ndizosakwanira mu potaziyamu, zobiriwira zobiriwira zimayamba kuonekera, kenako kutembenukira chikasu, ndikupanga masamba owoneka bwino. Zovuta kwambiri, m'mphepete mwa masamba imayamba kugwedezeka, ndipo mawanga a bulauni amayamba kulowa mkati. Chigawo cha masamba chimataya madzi ndikuchepa, tsamba limakhazikika kapena kukhazikika, ndipo pang'onopang'ono amagwedeza ndipo zimagwera, ndipo mbewu zamera zisanachitike.
Kodi ndiyenera kuchita chiyani ngati udzu wagona potaziyamu? Potaziyamu sikuti ndi michere yofunikira yokha chifukwa cha moyo wa chomera, komanso chimodzi mwazinthu zitatumbiri za feteleza. Zomwe zili mu potaziyamu muzomera ndi chachiwiri kokha kwa nayitrogeni. Kugwiritsa ntchito moyenera feteleza wa potaziyamu kumatha kukulitsa photosynthesis zomera za udzu komanso kukana kwawo matenda ndi tizirombo. Ngati zizindikiro za kuchepa kwa potaziyamu kumapezeka mu feteleza wa potaziyamu (monga potaziyamu chloride, potaziyamu sulfate, potaziyamu phosphate, etc.) ayenera kugwiritsidwa ntchito popewa ndi kuwongolera. Potaziyamu chloride ndi potaziyamu sulfate ndi feteleza wogwira ntchito mwachangu zomwe zingagwiritsidwe ntchito ngati feteleza wapansi ndikukopa. Ndikofunika kugwiritsa ntchito potaziyamu sulfate wa acidic nthaka ndi potaziyamu nitrate dothi lamthupi la alkaline.
Ngati udzu uli pamwambapa, njira zotsatirazi zingagwiritsidwe ntchito kuthana nazo:
1. Gwiritsani ntchito feteleza wochepera nayitrogeni mutatha kugwiritsa ntchito feteleza wa nayitrogeni.
2. Gwiritsani ntchito mizu yokhala ndi ma amino acid ndi kufufuza zinthu zopopera, makamaka kuti mubwezeretse ndikutsata zowonjezera.
3. Ikani potaziyamu sulfate 2kg / nthawi.
