NPK imaimira "nayitrogeni, phosphorus, ndi potaziyamu," zakudya zitatu zomwe zimapanga feteleza kwathunthu. Mudzakumana ndi makalata, NPK powerenga zomwe zili m'masamba a feteleza. Kufotokozera za feteleza sikunganene kuti "NPK", koma mudzawona nambala ya nambala zitatu, zomwe zimagwirizana, motsatizana, ndi zokhudzana ndi nitrogen, phosphorous, ndi potassium za feteleza.
Kumatanthauzanso ndi chizindikiro cha chiwerengero pambuyo pa nambala iliyonse chifukwa chiwerengero cha nambala zitatu chimaimira chiwerengero cha zakudya zomwe zimapezeka mu feteleza.
Nchifukwa chiyani nkofunika kudziwa zomwe NPK imatanthauza?
Si mitundu yonse ya zomera zomwe zimakhala ndi zofunikira zofanana, ndipo nthawi zina zimakhala zovulaza kuposa zabwino mukamagwiritsira ntchito mankhwala mosavuta. Kugwiritsa ntchito feteleza wokhala ndi nayitrogeni kumapangitsa mbewu zina kuika mphamvu zawo zonse kubala masamba osadya maluwa.
Ngati simukudziwa bwino momwe nthaka yanu ikuyendera zosowa za mbewu koma komabe mukuwona kuti mukufunikira kudyetsa izi panthawi inayake, phindu lanu ndilo:
- Gwiritsani ntchito kompositi mmalo mwa fetereza za mankhwala.
- Lembani nthaka yanu kuyesedwa.
- Gwiritsani ntchito feteleza yotulutsika pang'onopang'ono, yomwe siingathe kuvulaza zomera pamlingo uliwonse.
Zomwe Zomera Zomwe Zimapanga Zoonadi Zimatero
Kupititsa patsogolo zokambiranazi kuchokera ku maphunziro kupita kuntchito, tiyeni tiwone mwachidule ntchito zomwe mbali za NPK zimachita pakukula kwa mbeu:
- Mavitrogeni
- Phosphorus
- Potaziyamu
Nayitrogeni imalimbikitsa kukula kwa tsamba. Monga Kelly Burke akulemba, " Nayitrogeni ndi gawo lalikulu la chlorophyll ndi mtundu wobiriwira wa zomera." Monga tanenera kale, pangakhale chinthu monga "nayitrogeni wambiri". Kumapeto kosiyana siyana, amaluwa nthawi zina amakumana ndi vuto la kutayika kwa nayitrogeni .
Phosphorus imathandiza kwambiri pakukula kwa mizu, kufalikira, ndi fruiting, chifukwa chake ndi chofunikira kwambiri kwa mbeu yanu mumasika. Potaziyamu imathandizanso pa kukula kwa mizu komanso kukula.
Pogwiritsa ntchito chithunzichi, chogwiritsidwa ntchito pa chithunzi choperekedwa ndi chithunzi cha Scotts Turf Builder chomwe chinakonzedwa kuti chikuthandizeni udzu m'chilimwe. NPK mtengo uli ndi 28-0-8, kutanthauza kuti muli 28% ya nitrogen, phosphorous, ndi potassium 8% (potashi).
N'chifukwa chiyani kampaniyo imasiya phosphorous kunja kuno? Chomerachi chinali ndi phosphorous, koma Scotts akufotokoza kuti achotsa chifukwa cha chilengedwe. Phosphorous inasungidwa mu feteleza "Yoyambira" yomwe imapangidwa kuti igwiritsidwe ntchito kasupe, komabe chifukwa "phosphorous ndi yofunikira kuti mizu ya udzu ikhale yoyamba."
Kodi feteleza "oyenera" / "amphumphu" ndi ati?
Manyowa okwanira, kapena "feteleza oyenera", amatchedwa chifukwa ali ndi nayitrogeni, phosphorous, ndi potaziyamu - yaikulu 3 mu feteleza zosakaniza. Manyowa otchulidwa kuti "10-10-10," mwachitsanzo, angakhale amphumphu. Mmodzi wotchulidwa kuti "10-0-10" sungaganizidwe kukhala wangwiro, wotchedwa "feteleza chosakwanira."
Manyowa osakwanira sali otsika kwa feteleza wathunthu.
Chimene chiri chabwino chimadalira kwenikweni pa zochitika. Ngati nthaka yanu idakhala ndi mchere wambiri mu NPK, mungathe kuwononga zina mwa mbeu yanu powonjezera zambiri kunthaka - zomwe mukuchita (mosazindikira) pogwiritsa ntchito zonse feteleza. Ichi ndi chifukwa chake ndikofunika kuti nthaka yanu iyesedwe: mwinamwake, pamene muwonjezerapo kanthu pa nthaka yanu, zotsatira (kaya zabwino kapena zoipa) zatsala mwangozi.
