Kusarudza fetireza yeNPK yebindu rako rinogona kunge riri basa rakaoma kana usingazive zvinodiwa nezvirimwa zvako. Mafetereza eNPK ane nitrogen (N), phosphorus (P) uye potasium (K), zvinhu zvitatu zvakakosha zvekudyara kuti zvikure zvine hutano. Zvichienderana nerudzi rwechirimwa uye danho rekukura, chikamu chezvinhu izvi chinosiyana, saka zvakakosha kuziva kuti chii chakanyanya kusanganiswa.
Isu tichakuudza iwe Misiyano pakati peNPK fetireza, maitiro ekududzira chiyero chavo uye kuti ndeipi inonyanya kukodzera zvichienderana nerudzi rwechirimwa. Tichaona zvakare kuti zviri nani kusarudza mafetireza emvura kana kuti akasimba uye kuti tingaaisa sei nemazvo kuti tiwane mibairo yakanaka.
Fetereza yeNPK chii uye inoshandiswa nei?
Fetereza yeNPK inoumbwa nemacronutrients matatu akakosha anodiwa nezvirimwa pakukura kwawo:
- Nitrogen (N): Yakakosha pakukura kwemashizha nemadzinde, kukurudzira kukura kwakasimba uye yakanyanya kusvibira ruvara.
- Phosphorus (P): Yakakosha pakukura kwemidzi, maruva uye fruiting.
- Potassium (K): Inobatsira kumira kwechirimwa pazvirwere, inovandudza kunaka kwezvibereko uye inogadzirisa kutakurwa kwemvura mumiti yemiti.
Huwandu hwezvinhu izvi mumafetireza zvinosiyana zvichienderana nerudzi rwechirimwa uye danho rekukura kwayo. Semuenzaniso, 20-20-20 fetireza ine yakaenzana huwandu hweN, P uye K, nepo 10-10-30 ine yakakwirira potassium content, yakanakira zvirimwa mudanho remaruva.
Maitiro ekududzira zviyero zveNPK fetireza
Mapepa efertilizer anoratidza nhamba nhatu dzakapatsanurwa nemadhishi, senge 10-10-10 kana 12-24-12. Izvi zvinoratidza huwandu hwemacronutrient yega yega mumusanganiswa:
- Nhamba yekutanga inomiririra senitrogen (Kwete).
- Nhamba yechipiri inoratidza mutambo (P).
- Nhamba yechitatu inoenderana ne potasiamu (K).
Zvichienderana nerudzi rwechirimwa uye nguva yekukura kwayo, imwe formula inogona kunge yakakodzera kupfuura imwe. Semuyenzaniso:
- Zvezvirimwa zvidiki kana huswa huchangodyarwa: Yakakwirira phosphorus fertilizer, yakadai se 12-24-12, inokurudzirwa kukurudzira midzi yakasimba kukura.
- Zvezvinomera mashizha akasvibira: Fetereza ine nitrogen yakawanda, yakadai se20-5-5, inokurudzira kugadzirwa kwemashizha.
- Zvekutumbuka uye fruiting: A 10-20-20 inobatsira kukurudzira maruva uye kugadzirwa kwemichero ine utano.
Liquid vs. Organic Fertilizer solids: Ndeipi iri nani?
Mafetereza eNPK anowanikwa mune ese ari maviri emvura uye akasimba mafomu, imwe neimwe iine mabhenefiti ayo:
- Mafetireza akasimba: Kazhinji inowanikwa muchimiro chegranules kana poda. Izvo zvakakodzerwa nekushandiswa kwevhu uye zvine kunonoka kusunungurwa, kupa chikafu nekufamba kwenguva.
- Mafetireza emvura: Iwo anonyudzwa nekukurumidza, saka anobatsira mukuita fertigation kana foliar application. Vanobvumira kudya kwekukurumidza, asi kunoda kushandiswa kakawanda.
Sarudzo pakati pezvakaoma kana mvura zvinoenderana nerudzi rwechirimwa uye nzira yekushandisa yaunoda.
Mashandisirwo efotereza yeNPK nemazvo
Kuti fetereza ishande pasina kukuvadza zvirimwa, zvinokurudzirwa kushandisa zvinoenderana nemaitiro aya:
- Usapfuure muyero wakakurudzirwa: Fetereza yakawandisa inogona kupisa midzi yechirimwa.
- Iva nechokwadi chekugovera yunifomu: Tambanudza fetereza zvakanaka kutenderedza zvirimwa kuti udzivise kuwandisa munzvimbo imwechete.
- Mvura mushure mekushandisa: Izvi zvinobatsira kudya kunopinda muvhu uye kutorwa nemidzi.
Kana ukashandisa mafetireza emvura, wedzera kumvura yekudiridza maererano nemirairo yemugadziri. Kana iwe uchida kuziva zvakawanda nezve maitiro ekugadzira mafetiraiza emumba anobatsira zvidyarwa zvako, tarisa gwara redu pa mafetireza ekumba anobudirira.
Ndeipi fetireza yekusarudza zvinoenderana nerudzi rwechirimwa?
Kuita kuti zvive nyore kusarudza yakanakisa fetereza, tinokusiira mamwe mazano zvichienderana nerudzi rwechirimwa:
- Gwenzi: A high nitrogen fertilizer, yakadai se15-5-10, kukurudzira denser green canopy.
- Muriwo: Fetereza yakaenzana 10-10-10 kana ine phosphorus yakakwira kana vari padanho remaruva.
- Miti yemichero: Kunyanya nehuwandu hwe potassium, yakadai se10-5-20, kuwedzera kuumbwa uye kunaka kwezvibereko.
Zvakakosha kuziva zvinodiwa chaizvo zvezvirimwa zvako paunosarudza fetereza yakakodzera.
Kushandisa fetereza yakakodzera uye kuishandisa zvakanaka kunoita kuti bindu rako riwedzere kunaka. hutano uye nekukura kwakakwana.
