Precipitate (calcium hydrogen phosphate) yog cov tshuaj phosphate concentrated siv rau kev ua kom cov av ua ntej ua ntej cog lossis tseb cov qoob loo, ua cov ntxhia ntxiv rau cov tsiaj noj. Cov chiv no zoo li cas, cov mis precipitate zoo li cas, thiab yuav siv cov phosphate fertilizer precipitate, nyeem rau.
Yuav ua li cas thiaj paub nag lossis daus hauv khw
Sab nraud, calcium hydrogen phosphate yog xim dawb-dub, hmoov nrog suav nrog cov hmoov av zoo. Tsis ncuav mog qab zib thiab tsis yaj hauv dej. Yog li ntawd, solubility ntawm precipitate nyob rau hauv dej yog ib lo lus nug uas feem ntau nyiam gardeners thiab gardeners.
Nws zoo li cov hmoov nplej. Raws li txoj cai, tsis muaj teeb meem thaum siv cov chiv, tab sis nws raug nquahu kom them sai sai rau qee qhov nta:
- tshuaj tsis yaj hauv dej;
- ua ke nrog lwm cov tshuaj ntxhia, cov chiv ua haujlwmnquag nquag.
Hnub no, kev ua lag luam tau dhau los nrog ntau yam tshuaj fluorine-muaj cov chiv: superphosphates, phosphate pob zeb, tomasslag. Tab sis cov nag lossis daus yog qhov zoo tshaj plaws thiab ib qho ntawm thawj cov chiv uas muaj phosphorus.
Formula thiab muaj pes tsawg leeg ntawm cov khoom
Cov mis ntawm cov hmoov av yog raws li nram no: CaHPO 4·2H2O - dikaliyium phosphate dihydrate. Cov ntxhia-raws li tshuaj lom neeg muaj pes tsawg leeg yog tau los ntawm kev sib xyaw ntawm phosphoric acid thiab limestone lossis chalk, uas cuam tshuam nrog ib leeg. Cov kua qaub yog neutralized los ntawm kev tswj qhov kub thiab txias thaum lub sij hawm cov tshuaj tiv thaiv ntawm 50 o. Cov ntsiab lus fluorine hauv qhov muaj pes tsawg leeg yog 50%.
Cov txheej txheem ntawm cov chiv tsim nyog siv rau ntawm cov av podzolic. Active cuam tshuam cov acidity ntawm cov av, pab txo nws.
Vim li cas thiaj pom zoo siv cov ntxhia phosphate chiv hauv kev ua liaj ua teb
Yuav kom cog qoob loo zoo, koj yuav tsum ua haujlwm hnyav. Rau lub hom phiaj no, ntxiv rau txhawb kev loj hlob thiab flowering ntawm cov nroj tsuag, agronomists pom zoo kom siv chiv, piv txwv li, phosphorus, thaum lub sij hawm loj hlob txheej txheem. Precipitate yog tus sawv cev ci ntsa iab ntawm pawg hnav khaub ncaws no. Nws yog nquag siv ob qho tib si raws li kev ywj pheej chiv thiab ua ib feem ntawm lwm yam complexes.
Fertilizer, txawm nws yuav yog, yog lub luag haujlwm rau kev noj qab haus huv ntawm cov nroj tsuag, tau txais cov qoob loo zoo tshaj plaws. Tsis ntev los no, tsis yog xwborganic tebchaw, tab sis kuj mineral complexes uas yog enriched nrog tshuaj ntsiab. Lub ntsiab tseem ceeb nyob rau hauv muaj pes tsawg leeg ntawm precipitate yog phosphorus, uas yog lub luag hauj lwm rau fertility.
Yuav ua li cas phosphate chiv cuam tshuam rau cov nroj tsuag
Yog li, siv cov nag lossis daus ua ib qho hnav khaub ncaws saum toj kawg nkaus rau koj cov qoob loo, koj tuaj yeem suav daws cov teeb meem hauv qab no:
- nce qib yield;
- cog tiv taus ntau yam kab mob tiv thaiv kab mob;
- txhim kho cov yam ntxwv zoo ntawm cov txiv hmab txiv ntoo, suav nrog kev ua kom zoo;
- muag qhia txog kev txhim kho kev hnov lus zoo.
Precipitate yog cov chiv uas tuaj yeem siv tau rau txhua qhov av. Txawm hais tias cov tshuaj tiv thaiv tshwm sim zoo tshaj plaws ntawm cov av podzolic, vim tias lawv muaj oxidation ntau dua li lwm tus.
Ib qho tshwj xeeb ntawm cov hmoov uas tsis yaj hauv dej yog qhov tawg sai sai rau hauv ib tus neeg cov khoom hauv ib puag ncig acidic, uas tso cai rau cov av saturating nrog phosphorus sai dua. Qhov no cov nyhuv yog ntau pronounced thaum fertilizing hluas cultivated nroj tsuag, lub hauv paus system ntawm uas tseem tsis tau tag nrho tsim. Nws yog phosphorus uas ua rau nws muaj zog thiab muaj zog. Thiab nws kuj yog lub luag haujlwm rau kev nce qib suab thaj hauv cov txiv hmab txiv ntoo, uas cuam tshuam ncaj qha rau kev saj ntawm cov qoob loo yav tom ntej.
Ib yam ntawm precipitate raws li ib tug fertilizer yog txhawb nqa uptake los ntawm cov nroj tsuag ntawm tsis zoo soluble ntsev uas muaj nyob rau hauv cov pob zeb nyuaj av.
Lub hauv paus ntsiab lus ntawm phosphate fertilizer yog dab tsi
Txoj hauv paus ntsiab lusprecipitate - phosphate chiv thiab ntxhia chiv rau zaub thiab horticultural qoob loo, nrog rau pub rau cov tsiaj loj, nyob rau hauv nws cov tswv yim zoo li lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm lwm yam muaj pes tsawg leeg raws li phosphorus. Qhov sib txawv tsuas yog lub sijhawm ntawm cov txheej txheem, uas ntev dua rau calcium hydrogen phosphate (precipitate). Dab tsi tsis tuaj yeem hais txog superphosphate, uas decomposes ntau zaus sai dua hauv qhov chaw acidic. Raws li qhov no, nws tsis yog qhov nyuaj rau xav txog yuav ua li cas sai sai cov nroj tsuag tsis muaj zog yuav saturated nrog tag nrho cov as-ham tsim nyog rau kev noj qab haus huv thiab kev loj hlob.
Ntawm cov yam ntxwv ntawm calcium hydrogen phosphate yog lwm qhov zoo tshaj plaws - precipitate yog cov muaj pes tsawg leeg uas tsis muaj teeb meem rau cov av thiab cov nroj tsuag piv rau lwm cov khaub ncaws saum toj kawg nkaus uas muaj phosphorus. Qhov no tau piav qhia banally - qhov tsawg kawg nkaus cov ntsiab lus ntawm chemistry.
Yuav ua li cas nkag siab tias tsob ntoo yuav tsum tau noj
Ntawm cov cim tseem ceeb uas cov nroj tsuag xav tau fertilized nrog precipitate yog cov hauv qab no:
- hauv qab nplooj ntawm cov nroj tsuag tau hloov ntshav nrog cov ntshav tint, es tsis txhob noj qab nyob zoo tsaus ntsuab;
- hloov nplooj ntoo;
- cog kev loj hlob qeeb lossis nres tag nrho;
- kev noj zaub mov tsis txaus ntawm huab cua ntawm cov nroj tsuag vim tsis muaj zog ntawm cov hauv paus hniav.
Raws li koj twb tau nkag siab lawm, cov nag lossis daus yog ib qho khoom siv tseem ceeb hauv kev ua liaj ua teb, suav nrognoj qab nyob zoo kev sib tw rau lwm yam formulations vim nws txoj kev nyab xeeb thiab kev ua tau zoo. Nws yuav yog ib qho kev pab zoo rau tus neeg ua teb. Peb cia siab tias cov ntaub ntawv muab los yuav pab tau ob tus neeg pib thiab cov neeg ua haujlwm paub txog kev xaiv chiv rau lawv lub vaj lossis zaub vaj.
