Nkhani

1. Feteleza wa nayitrojeni: Akhoza kulimbikitsa kukula kwa nthambi za zomera ndi masamba, kumapangitsanso photosynthesis ya zomera, kuonjezera kuchuluka kwa chlorophyll, ndi kukulitsa chonde m’nthaka.
2. Feteleza wa Phosphate: Limbikitsani kupanga ndi kuphuka kwa maluwa, pangani tsinde ndi nthambi zake kukhala zolimba, zipatso zokhwima msanga, ndikuthandizira kuzizira kwa mbewu ndi chilala.
3. Feteleza wa potaziyamu: Imalimbitsa tsinde la zomera, imathandiza kuti zomera zisawonongeke ndi matenda, kuti zisawonongeke ndi tizilombo, zimalimbana ndi chilala, komanso zimathandiza kuti zipatsozo zikhale zabwino.

1. Udindo waFeteleza wa NPK
N. P ndi K amatchula feteleza wa nayitrogeni, feteleza wa phosphorous, ndi feteleza wa potaziyamu, ndipo ntchito zake ndi izi.
1. Feteleza wa nayitrojeni
(1) Limbikitsani photosynthesis ya zomera, kulimbikitsa nthambi za zomera ndi kukula kwa masamba, kuwonjezera ma chlorophyll, ndi kukulitsa chonde m'nthaka.
(2) Ngati feteleza wa nayitrogeni alibe kusowa, zomera zimafupikitsa, masamba ake amasanduka achikasu ndi obiriwira, kukula kwawo kumachedwa, ndipo sangathe kuphuka.
(3) Ngati feteleza wa nayitrogeni ali wochuluka, minofu ya zomera imakhala yofewa, tsinde ndi masamba zimakhala zazitali kwambiri, kuzizira kumachepa, ndipo n’zosavuta kutenga matenda ndi tizirombo.
2. Feteleza wa Phosphate
(1) Ntchito yake ndi kupanga tsinde ndi nthambi za zomera kukhala zolimba, kulimbikitsa mapangidwe ndi maluwa a maluwa, kupangitsa kuti zipatso zikhwime msanga, ndikuwongolera chilala ndi kuzizira kwa zomera.
(2) Zomera zikapanda phosphatefetereza, zimakula pang’onopang’ono, masamba, maluwa ndi zipatso zake zimakhala zazing’ono, ndipo zipatso zake zimakhwima mochedwa.
3. Feteleza wa potaziyamu
(1) Ntchito yake ndi kupanga tsinde la mbewu kukhala lolimba, kulimbikitsa kukula kwa mizu, kupititsa patsogolo kukana matenda a zomera, kukana tizilombo, kukana chilala, kukana malo ogona, ndi kusintha khalidwe la zipatso.
(2) Ngati pali kusowa kwa potaziyamu feteleza, mawanga a necrotic adzawoneka pamphepete mwa masamba a zomera, kenako ndikufota ndi necrosis.
(3) Kuchuluka kwa potaziyamu feteleza kumabweretsa kufupikitsa mbewu za internodes, kufupikitsa matupi a zomera, masamba achikasu, ndipo zowopsa, imfa.
2, Ndi feteleza wamtundu wanjiNPK fetelezaza?
1. Feteleza wa nayitrojeni
(1) Nayitrogeni ndiye chigawo chachikulu cha michere ya feteleza, makamaka kuphatikiza urea, Ammonium bicarbonate, ammonia, ammonium chloride, ammonium nitrate, ammonium sulfate, etc. Urea ndiye feteleza wolimba wokhala ndi nayitrogeni wambiri.
(2) Pali mitundu yosiyanasiyana ya feteleza wa nayitrogeni, amene angagaŵidwe kukhala feteleza wa nayitrogeni wa nitrate, feteleza wa nayitrogeni wa ammonium nitrate, feteleza wa nayitrogeni wa cyanamide, feteleza wa ammonia nayitrojeni, feteleza wa ammonium nitrogen, ndi feteleza wa nayitrogeni wa amide.
2. Feteleza wa Phosphate
Chomera chachikulu cha feteleza ndi phosphorous, makamaka kuphatikiza superphosphate, calcium magnesium phosphate, phosphate rock powder, fupa la mafupa (nyama ya mafupa, chakudya cha mafupa a nsomba), chinangwa cha mpunga, sikelo ya nsomba, Guano, etc.
3. Feteleza wa potaziyamu
Potaziyamu sulphate, potaziyamu nitrate, potaziyamu kloride, phulusa la nkhuni, ndi zina zotero. Potaziyamu sulphate, potaziyamu nitrate, potaziyamu kloride, phulusa la nkhuni, etc.
