Polima zomera zokhala ndi miphika, malo ochepa mumphika amachititsa kuti zikhale zovuta kuti zomera zitenge chakudya chokwanira kuchokera m'nthaka. Chifukwa chake, kuti zitsimikizike kuti zikule bwino komanso maluwa ambiri, feteleza wa masamba nthawi zambiri amafunika. Nthawi zambiri, sikoyenera kuthira manyowa mbewu zikayamba kuphuka. Ndiye, kodi mbewu zophikidwa mumiphika zitha kupopera mbewu mankhwalawa ndi feteleza wa foliar panthawi yakuphuka? Tiyeni tione bwinobwino!

1. Ayi

Zomera zokhala m'miphika siziyenera kuthiriridwa feteleza pamene zikupanga maluwa-osati kudzera mu umuna kapena kupopera mbewu mankhwalawa. Feteleza panthawi yamaluwa zimatha kuyambitsa kuphukira ndi kugwa kwa maluwa. Izi zimachitika chifukwa, pambuyo pa umuna, mbewuyo imatsogolera michere ku mphukira zam'mbali zomwe zimamera, zomwe zimapangitsa kuti masambawo asowe chakudya ndikugwa. Kuonjezera apo, maluwa ongophuka kumene amatha kufota msanga pambuyo pa ubwamuna.

2. Manyowa Musanapange maluwa

Pofuna kulimbikitsa maluwa ochulukirapo muzomera zomiphika, kuthirira kumachitika bwino musanayambe maluwa. Kugwiritsa ntchito feteleza woyenerera wa phosphorous-potaziyamu panthawiyi kumathandiza kulimbikitsa mapangidwe a masamba, kumawonjezera nthawi ya maluwa, ndikuwonjezera kukongola. Dziwani kuti feteleza wa nayitrogeni weniweni ayenera kupewedwa asanatulutse maluwa, chifukwa angayambitse kukula kwa zomera ndi masamba ambiri koma maluwa ochepa.

3. Feteleza Wamba wa Foliar

Feteleza wamba wa zomera zophika ndi potassium dihydrogen phosphate, urea, ndi ferrous sulfate. Kuonjezera apo, ammonium nitrate, ferrous sulfate, ndi sodium dihydrogen phosphate angagwiritsidwenso ntchito pamasamba. Manyowawa amalimbikitsa kukula kwa mbewu, kusunga masamba obiriwira komanso onyezimira, motero amawongolera kukongola kwawo.

4. Njira ya feteleza

Kuchuluka kwa feteleza kuyenera kuyendetsedwa mosamala, chifukwa madzi ochulukirapo amatha kutentha masamba. Nthawi zambiri, feteleza wa masamba ayenera kukhala pakati pa 0.1% ndi 0.3%, kutsatira mfundo ya "pang'ono komanso pafupipafupi." Konzani feteleza wosungunuka ndikuthira mu botolo lopopera, kenaka mulowetsenso nkhungu pamasamba a mmera, kuwonetsetsa kuti pansi ndi yokutidwa mokwanira.
