Cov tsiaj ntawv "NPK" ntawm daim ntawv qhia chiv sawv rau nitrogen, phosphorus, thiab poov tshuaj, peb lub ntsiab as-ham cov nroj tsuag yuav tsum loj hlob. Cov lej ntawm daim ntawv qhia txog qhov sib piv (los ntawm feem pua) ntawm nitrogen, phosphorus, thiab poov tshuaj nyob rau hauv cov chiv.
Txawm hais tias koj tsis pom cov ntawv NPK, tab sis koj pom ib pawg ntawm peb tus lej, piv txwv li, 5-10-5, koj tuaj yeem xav tias nws yog 5 feem pua nitrogen, 10 feem pua phosphorus, thiab 5 feem pua poov tshuaj, ib txwm nyob hauv. tias xaj. Cov chiv no muaj 20 feem pua cov as-ham; qhov seem 80 feem pua yog cov khoom noj me me lossis cov fillers. Cov nroj tsuag xav tau txog 16 cov as-ham; Qee qhov lawv tau txais los ntawm huab cua thiab dej, thiab lwm tus yog cov khoom noj xws li hlau, calcium, thiab chlorine los ntawm av.
Kev Ua Haujlwm Li Cas vs. Fertilizer Quantities
Ib qho me me ntawm cov chiv nrog qhov sib piv ntau dua tuaj yeem yog tib yam li qhov ntau dua nrog cov lej qis dua. Piv txwv li, ib lub hnab 5- phaus ntawm 10-20-10 chiv muaj cov khoom noj muaj txiaj ntsig zoo ib yam li 10 phaus ntawm 5-10-5 chiv.
Cov khoom xyaw hauv NPK ua dab tsi?
Tag nrho peb cov khoom xyaw yog qhov tseem ceeb rau kev cog qoob loo. Ntawm no yog saib luv luv ntawm txhua yam khoom noj muaj txiaj ntsig dab tsi.
Nitrogen
Nitrogen, thawj tus lej hais txog hauv NPK ib ntus, ua lub luag haujlwm tseem ceeb hauv cov nroj tsuag xim thiab chlorophyll ntau lawm, ua rau nws yog ib qho tseem ceeb hauv kev loj hlob nplooj. Fertilizers siab nyob rau hauv nitrogen feem ntau yog siv rau cov nyom los yog lwm yam nroj tsuag uas ntsuab foliage loj hlob yog tseem ceeb tshaj flowering. Ntawm qhov kawg ntawm qhov spectrum, cov neeg ua teb qee zaum ntsib teeb meem ntawm nitrogen depletion-qhov yellowing ntawm cov nroj tsuag ntsuab feem ntau qhia tias tsis muaj nitrogen.
Phosphorus
Tus lej nruab nrab hauv NPK series hais txog qhov feem pua ntawm phosphorous hauv cov khoom siv chiv. Phosphorus plays lub luag haujlwm tseem ceeb hauv kev loj hlob ntawm cov hauv paus hniav, tawg, thiab txiv hmab txiv ntoo, uas yog vim li cas nws yog ib qho tseem ceeb rau koj cov nroj tsuag thaum caij nplooj ntoos hlav. Phosphorus pab txhawb rau ntau yam hauv paus txheej txheem, xws li rooting thiab noob tsim.
Potassium
Tus lej kawg hauv cov khoom xyaw tseem ceeb muab cov feem pua ntawm cov poov tshuaj hauv cov khoom. Potassium pab txhawb kev noj qab haus huv tag nrho thiab muaj zog ntawm cov nroj tsuag. Nws paub tias yuav pab ntxiv dag zog rau cov nroj tsuag muaj peev xwm tiv thaiv kab mob, pab txhawb kev txav ntawm cov dej thiab cov as-ham hauv cov nroj tsuag, thiab tuaj yeem yog qhov tseem ceeb tshwj xeeb hauv thaj chaw uas muaj huab cua txias lossis qhuav.2
Lwm cov khoom xyaw
Ntxiv rau cov khoom noj tseem ceeb uas feem ntau tau sau tseg rau ntawm daim ntawv lo rau pem hauv ntej, feem ntau cov chiv tseem muaj cov khoom xyaw ntxiv uas tau teev tseg rau ntawm ib sab lossis sab nraub qaum. Qhov no yuav suav nrog lwm cov as-ham xws li calcium, magnesium, hlau, micronutrients, thiab txawm tias feem pua ntawm cov organic teeb meem thiab cov fillers. Txawm hais tias cov zaub mov thiab micronutrients yog qhov tseem ceeb tsawg dua li cov as-ham loj, cov khoom siv chiv zoo yuav suav nrog me me ntawm lwm cov khoom xyaw thiab.
Hom NPK Fertilizers
Sib npaug Fertilizers
Ib qho chiv uas tau teev tseg raws li "10-10-10" yog suav tias yog qhov sib npaug lossis "ua tiav" vim tias nws cov nitrogen, phosphorus, thiab potassium proportions sib npaug. Lub caij no, cov chiv sau npe "10-0-10" yog "cov chiv tsis tiav."
Fertilizer tsis tiav
Ib qho chiv tsis tiav tsis tas yuav qis dua rau cov chiv ua tiav. Kev txheeb xyuas cov chiv zoo rau koj cov kev xav tau yog nyob ntawm ntau yam xwm txheej. Yog tias koj cov av twb muaj ntau tshaj ntawm ib qho ntawm peb cov as-ham hauv NPK, koj tuaj yeem ua mob rau qee yam ntawm koj cov nroj tsuag los ntawm kev ntxiv rau hauv av - qhov no, cov chiv tsis tiav lossis tsis sib npaug yuav yog qhov kev xaiv zoo.
Vim li no, nws yog ib qho tseem ceeb uas yuav tau sim koj cov av ua ntej thov chiv. Txwv tsis pub, thaum twg koj ntxiv ib yam dab tsi rau koj cov av, cov nyhuv (txawm tias qhov zoo lossis qhov tsis zoo) raug tso tseg.
Organic Fertilizers
Organic fertilizer cov khoom xyaw yog cov as-ham hauv av los ntawm cov nroj tsuag, tsiaj txhu, los yog pob zeb hauv av. Cov khoom uas sau tias "organic chiv" yuav tsum qhia meej tias cov as-ham yog cov organic thiab yuav tsum raug txheeb xyuas tias yog hluavtaws lossis ntuj los ntawm feem pua. Piv txwv li, daim ntawv lo yuav nyeem, "20 feem pua ntawm nitrogen (6 feem pua synthetic, 14 feem pua cov organic).
Organic chiv tej zaum yuav muaj xws li quav quav, alfalfa pluas mov, kelp, ntshav thiab pob txha noj mov, ntses emulsion, paj rwb noob, dej phwj sludge, mos pob zeb phosphate, thiab ntsuab xuab zeb.
Qhov "Organic" txhais li cas hauv Fertilizer
Kev hais lus, cov khoom siv "organic" yog txhua yam uas muaj carbon atoms. Lub ntsiab lus niaj hnub ntawm "organic" txhais tau tias nws tsis muaj dab tsi hluavtaws; Txawm li cas los xij, "organic chiv" tej zaum yuav muaj cov khoom siv ntuj tsim los yog hluavtaws, tab sis cov feem pua ntawm txhua tus yuav tsum tau cim. Yog li, yog tias koj xav tau dab tsi yog "cov chiv uas tsis yog hluavtaws," nyeem daim ntawv lo kom zoo rau txhua yam khoom xyaw ua ntej yuav khoom vim lo lus "organic" tsis npog nws.
Tsim nyog yuav tsum tau nco ntsoov, organic chiv ua tag nrho los ntawm cov khoom xyaw ntuj feem ntau muaj qis dua ntawm peb cov as-ham loj, yog li koj yuav tau siv ntau dua. Lub upside yog lawv feem ntau muaj ntau cov as-ham ntxiv uas pub cov nroj tsuag thiab av. Nws raug pom zoo tias yog tias koj tsuas yog siv cov khoom siv hluav taws xob ua lag luam, ntxiv rau qee yam ntawm cov organic teeb meem, xws li compost los yog manure, rau ntau holistic av noj qab haus huv.
Yuav Ua Li Cas Xaiv Cov Fertilizer Zoo
Txhawm rau muab koj cov nroj tsuag cov as-ham uas lawv xav tau, ntsuas qhov lawv muaj tam sim no (lossis yuav muaj yog tias cog tshiab). Tsis yog txhua hom nroj tsuag muaj tib yam khoom noj uas yuav tsum tau ua, thiab qhov kev xav tsis zoo yuav tshwm sim yog tias kev hloov kho tau siv haphazardly.
Kev hloov kho yog cov tshuaj ntxiv, xws li chiv, uas koj ntxiv rau hauv av kom txhim kho nws cov mob; lawv tuaj yeem kho ntau yam, suav nrog kev noj zaub mov, dej permeability, lossis qib pH. Agricultural txiv qaub yog ib hom kev hloov kho uas koj siv los txo cov acidity hauv cov av, ib yam li cov xuab zeb lossis grit yog ib qho kev hloov kho uas siv los ua kom cov porosity ntawm cov av los pab hauv cov kua dej.
Yog tias koj tsis xaiv cov chiv zoo, thiab yog tias koj cov av pH twb siab dhau lossis qis dhau lawm, koj cov nroj tsuag tsis tuaj yeem nkag mus rau qee cov as-ham txawm tias koj muab cov chiv rau lawv. Paub txog dab tsi twb muaj nyob rau hauv koj cov av yog ib qho tseem ceeb heev vim hais tias koj muaj peev xwm ua phem ntau tshaj qhov zoo thaum thov ib tug fertilizer siab nyob rau hauv nitrogen rau ib tug twb muaj nitrogen-nplua nuj av. Piv txwv li, nitrogen pub foliage ntawm tus nqi ntawm paj, uas tuaj yeem cuam tshuam rau paj paj.
Nov yog cov kauj ruam rau kev xaiv cov chiv zoo:
Ntsuam xyuas koj cov av.Muaj kev sim av ua ntej koj pib ntxiv cov kev hloov kho yuav qhia koj tias koj xav tau dab tsi. Koj tuaj yeem ua ib qho kev sim hauv tsev, xa cov qauv av rau kev sim, lossis hu rau koj lub koom haum txuas ntxiv hauv zos rau kev taw qhia.
Txiav txim siab seb koj cog dab tsi.Qee cov nroj tsuag yuav xav tau ntau dua lossis tsawg dua ntawm qee yam khoom noj. Piv txwv li, nplooj nplooj ntsuab xav tau nitrogen ntau dua, thaum muaj phosphorus ntau ntxiv rau cov txiv hmab txiv ntoo thiab paj. Ua ntej koj pib ua vaj lossis cog qhov project; muaj kev nkag siab ruaj khov ntawm cov nroj tsuag koj loj hlob thiab nws cov chiv xav tau.
Tshawb xyuas cov chiv tshwj xeeb uas tsim rau cov nroj tsuag koj loj hlob.Koj tuaj yeem nrhiav tau cov chiv ua ntej rau cov nyom, ntoo, qhov muag teev, cacti, houseplants, paj, txiv hmab txiv ntoo thiab zaub, acid-hlub nroj tsuag, thiab ntau ntxiv. Feem ntau yuav phim los yog tuaj ze rau cov khoom noj uas koj xav tau, xav txog koj cov av nruab nrab, yog li kho kom haum raws li koj cov av tsom xam.
Nyeem daim ntawv txheeb xyuas chiv ua ntej yuav chiv.Yog tias koj tsis tuaj yeem pom cov chiv nrog qhov tseeb NPK piv koj xav tau raws li koj qhov kev sim av, tuaj ze li sai tau. Ntawm peb cov as-ham, nws tseem ceeb dua kom tau txais cov nitrogen kom raug thiab tsis txhob overdo cov phosphorus vim nws tuaj yeem cuam tshuam cov dej kom tsawg.3
Txiav txim siab daim ntawv ntawm cov chiv koj xav tau.Yog tias koj tab tom tsim cov nyom tshiab, koj tuaj yeem xav txog kev siv cov chiv tawm sai uas yog txau rau hauv cov kua dej. Los yog, koj tuaj yeem sim cov chiv granulated rau ib daim ntawv tso tawm qeeb ntawm cov zaub mov rau cov nroj tsuag thiab nws cov hauv paus hniav thaum lub sij hawm. Feem ntau cov lus qhia txog kev loj hlob thiab kev saib xyuas cov nroj tsuag yuav sau cov khoom noj sib piv, kua vs. cov ntaub ntawv qhuav, thiab cov lus pom zoo rau kev tso tawm qeeb.
Yog tias tsis paub meej, siv compost.Yog tias koj tsis tau kuaj xyuas koj cov av thiab tsis nkag siab tias nws ua tau raws li cov nroj tsuag xav tau kev noj haus zoo npaum li cas tab sis tseem xav tias yuav tsum tau pub nws, siv compost es tsis txhob siv cov chiv ua lag luam lossis xav txog kev siv cov chiv qeeb. Kev tso tawm qeeb tsis tshua muaj kev phom sij rau cov nroj tsuag mus rau ib qho kev kawm zoo.
Yuav Siv Fertilizer li cas
Txij li txhua cov nroj tsuag muaj cov chiv sib txawv, peb paub tias ib tsob ntoo yuav xav tau chiv ntau dua thaum lwm tus yuav xav tau tsawg dua lossis tsis muaj dab tsi. Feem ntau, cov sij hawm ua chiv tsis tu ncua yuav ua rau koj cov nroj tsuag muaj zog. Txawm li cas los xij, cov chiv ntau dhau tuaj yeem tua koj cov nroj tsuag, feem ntau hlawv cov nplooj thiab cov hauv paus hniav yog tias muab ntau dhau sai lossis siv ncaj qha rau ntawm nplooj.
Txhawm rau paub txog kev siv thiab siv chiv ntau npaum li cas, ua raws li cov lus qhia ntawm daim ntawv lo nrog cov nroj tsuag cov lus qhia tshwj xeeb. Tsis tas li, tshawb xyuas koj lub chaw haujlwm txuas ntxiv hauv zos rau cov lus pom zoo rau kev xav tau chiv hauv koj cheeb tsam; qee thaj tsam muaj cov av acidic ntau dua li lwm tus.4
Piv txwv li, peb paub nyob rau lub caij nplooj ntoos hlav ib nyom nyom yuav tsum muaj nitrogen-nplua nuj chiv.4 Ib phaus ntawm nitrogen tej zaum yuav raug pom zoo rau 1, 000 square feet ntawm nyom. Yog tias koj cov nyom yog 1, 000 square feet thiab koj cov chiv muaj 20 feem pua nitrogen, koj yuav tsum sib npaug 10 phaus ntawm cov chiv rau tag nrho koj cov nyom.5 Feem ntau, cov nyom tau txais txiaj ntsig los ntawm cov chiv ib hlis ib zaug. Plaub Hlis Ntuj txog Kaum Ib Hlis, nrog kev ncua thaum lub caij kub tshaj plaws ntawm Lub Xya Hli thiab Lub Yim Hli; Txawm li cas los xij, qhov no yog qhov sib txawv raws li qhov nplua nuj ntawm cov av uas twb muaj lawm. Yog li ntawd, kev txheeb xyuas av tseem ceeb heev. Koj yeej tsis xav kom dhau-fertilize, yog tias koj tuaj yeem zam tau.
Cov kev hloov pauv uas cuam tshuam ntau npaum li cas thiab ntau npaum li cas koj yuav tsum tau fertilize:
Hom nroj tsuag
Slow-tso vs. ceev-tso chiv
Mowing xyaum (lawns)
Dej
Huab cua thiab kub
Av kev ntxhib los mos
Av pH
Ceeb toom
Tsis txhob overfertilizing koj cov nroj tsuag, tshwj xeeb tshaj yog cov nyom. Cov zaub mov uas tsis tau coj los ntawm cov nroj tsuag tuaj yeem nkag mus rau hauv cov kav dej thiab cov dej ntws, ua rau muaj teeb meem loj.6
Yuav Siv Fertilizer li cas
Nws yog feem ntau pom zoo kom siv chiv thaum lub hnub tsis raug ntaus rau ntawm cov nroj tsuag. Txawm li cas los xij, kev thov nws ua ntej los yog tom qab los nag los yog cov nroj tsuag watering nyob ntawm daim ntawv ntawm chiv koj siv. Fertilizer tuaj nyob rau hauv granules, kua, hmoov, los yog spikes.
Granular fertilizer:Cov chiv qhuav no tuaj rau hauv cov duab pellets, feem ntau yog siv rau cov nyom. Feem ntau granular chiv yog qeeb-tso chiv, muab cov as-ham rau cov nyom nyob rau lub sij hawm ntev. Hom chiv no siv cov chiv tshwj xeeb tshaj tawm raws li cov cuab yeej-tshaj tawm, poob, lossis cov khoom siv tes tuav. Nws yog qhov zoo tshaj plaws los siv cov chiv no ua ntej los nag vim tias qhov kev tso tawm qeeb qeeb siv cov dej nag los ua nws txoj kev faib tawm. Ntawm cov nyom ntub, cov granules yuav lo rau nplooj, ua rau muaj kev pheej hmoo ntawm hlawv.
Kua, hmoov, los yog siv lead ua chiv:Daim ntawv no feem ntau yog muag raws li cov kua concentrated, qhuav hmoov, los yog muaju uas yuav tsum tau ntxiv dilution nrog dej. Feem ntau cov kua chiv yog cov kev daws teeb meem sai, uas txhais tau hais tias cov as-ham tam sim ntawd dhau mus rau cov nroj tsuag Txau thiab hose txuas ua kom kis tau cov chiv no yooj yim. Txau cov chiv no rau ntawm cov nyom uas twb ntub lawm kom txwv "hlawv" los ntawm cov tshuaj.
Spikes:Xav txog spikes rau kev teeb tsa-thiab-tsis nco qab-nws mus kom ze rau fertilizing. Spikes feem ntau yog hom chiv kim tshaj plaws tab sis yooj yim siv. Spikes yog qeeb-tso tawm, lim cov as-ham los ntawm qhov dav mus rau cov av dhau sijhawm. Spikes yog tsim rau ntoo, shrubs, sab nraum zoov nroj tsuag, thiab houseplants. Feem ntau, cog cov pob txha hauv cov av mos, ntub dej ntawm txoj kab drip (qhov taw tes uas dej poob los ntawm tsob ntoo lossis cog rau hauv cov hauv paus hniav).
