Momwe mungathanirane ndi kusowa kwa potaziyamu m'munda

Poyamba kusowa kwa potaziyamu,chomera cha udzuMasamba amakula pang'onopang'ono komanso masamba obiriwira akuda. Zizindikiro zazikulu za kusowa kwa potaziyamu: nthawi zambiri masamba akale ndi m'mphepete mwa masamba zimasanduka zachikasu poyamba, kenako zofiirira, zopsereza ndi kupsa, ndipo madontho ndi madontho a bulauni amaonekera pamasamba, koma pakati, mitsempha ndi madera omwe ali pafupi ndi mitsempha amakhalabe obiriwira. Pamene kusowa kwa potaziyamu kukuwonjezeka, tsamba lonse limakhala lofiirira kapena louma, limatupa ndikugwa; masamba ena a zomera ndi amkuwa, opindika pansi, okhala ndi minofu ya mesophyll pamwamba pa tsamba ndi mitsempha yolowa. Zomera zikasowa potaziyamu, mizu imawonongekanso kwambiri, yokhala ndi mizu yochepa komanso yochepa, yomwe imatha kukalamba msanga, kuola nthawi zovuta, komanso kukhala pamalo a mizu. Zomera za udzu zikasowa potaziyamu, madontho a bulauni amaonekera pamasamba otsika, ndipo nthawi zovuta, zizindikiro zomwezo zimawonekera pamasamba atsopano. Masamba ndi ofewa komanso ofooka, tsinde ndi lopyapyala komanso lofooka, ndipo ma internodes ndi afupiafupi; pamene zomera za nyemba sizikusowa potaziyamu, zobiriwira zapakati pa mitsempha zimawonekera koyamba, kenako zimakhala zachikasu, ndikupanga masamba okhala ndi madontho. Pa milandu yoopsa, m'mphepete mwa masamba mumayamba kupsa ndi kupindika pansi, ndipo madontho a bulauni amamera mkati mwa mtsempha. Khungu la tsamba limataya madzi ndi kufooka, pamwamba pa tsamba limapindika kapena kupindika, ndipo pang'onopang'ono limapsa ndi kugwa, ndipo chomera chimakalamba msanga.

Kodi ndiyenera kuchita chiyani ngati udzu ulibe potaziyamu? Potaziyamu si michere yofunika kwambiri pa moyo wa zomera, komanso ndi chimodzi mwa zinthu zitatu zomwe zili mu feteleza. Kuchuluka kwa potaziyamu m'zomera ndi kwachiwiri kuposa nayitrogeni. Kugwiritsa ntchito bwino feteleza wa potaziyamu kungathandize kuti zomera za udzu zizitha kupanga photosynthesis komanso kuti zisadwale matenda ndi tizilombo toononga. Ngati zizindikiro za kusowa kwa potaziyamu zikupezeka posamalira udzu, feteleza wa potaziyamu (monga potaziyamu chloride, potaziyamu sulfate, potaziyamu phosphate, ndi zina zotero) ziyenera kugwiritsidwa ntchito popewa ndi kulamulira. Potaziyamu chloride ndi potaziyamu sulfate zonse ndi feteleza zomwe zimagwira ntchito mwachangu zomwe zingagwiritsidwe ntchito ngati feteleza woyambira komansokupaka pamwambaNdi bwino kugwiritsa ntchito potaziyamu sulfate pa nthaka yokhala ndi asidi ndi potaziyamu nitrate pa nthaka yokhala ndi alkaline.

Ngati udzu uli ndi zizindikiro zomwe zili pamwambapa, njira zotsatirazi zingagwiritsidwe ntchito pothana nawo:

1. Ikani feteleza wochepa wa nayitrogeni ndipo thirirani madzi nthawi yomweyo mukangoyika feteleza wa nayitrogeni.

2. Gwiritsani ntchito zinthu zozula mizu zokhala ndi ma amino acid ndi zinthu zochepetsera zomera popopera, makamaka pobwezeretsa mizu ndi kuwonjezera zinthu zochepetsera zomera.

3. Pakani potassium sulfate 2kg/nthawi.
