Mineral chiv yog lub hauv paus ntawm kev ua liaj ua teb niaj hnub no. Lawv tso cai rau koj kom muaj txiaj ntsig zoo ntawm cov av tsis zoo, uas ua rau nws muaj peev xwm loj hlob cov qoob loo nplua nuj nyob hauv yuav luag txhua cheeb tsam ntawm lub tebchaws. Xav txog tias cov yam ntxwv ntawm cov av hauv feem ntau ntawm peb cheeb tsam nyob deb ntawm qhov zoo tshaj plaws, qhov no yog ib qho khoom muaj nqis heev.

Tau kawg, lawv cov kev xaiv yuav tsum tau ua kom tiav nrog txhua lub luag haujlwm, txij li kev siv cov chiv ntau dhau ntawm cov ntxhia hauv av tuaj yeem ua rau tsis yog tsuas yog kev tuag ntawm cov nroj tsuag, tab sis kuj ua rau lom neeg nrog nitrates thiab nitrites. Ib qho txiaj ntsig zoo tshaj plaws ntawm hom no yog ob npaug superphosphate.

Thaum twg yuav tsum tau siv?

xav tias koj muaj lub vaj zoo nkauj zoo nkauj. Muaj ib hnub koj yuav pom tias qhov xwm txheej ntawm nplooj ntawm cov nroj tsuag tawm ntau yam uas xav tau: qhov qis ntawm nplooj nplooj tig ib qho tsis zoo li ntsuab-ntsuab ntxoov ntxoo, thiab cov qoob loo poob qis heev … Cov cim qhia tias koj xav tau ceev. Muab ob npaug rau superphosphate.

Tsis tas li ntawd, ib qho kev ntseeg ncaj ncees kuj yogpoob zes qe menyuam, uas yog rhiab heev rau qhov tsis muaj ntau yam kab.

phosphorus yog dab tsi?

Nco ntsoov tias txhua yam nroj tsuag ntawm peb lub ntiaj teb xav tau cov tshuaj no. Qhov teeb meem yog tias nyob rau hauv cov av, cov ntsiab lus ntawm cov phosphorus compounds tsis tshua muaj ntau tshaj 1%, thiab nyob rau hauv feem ntau cov cheeb tsam no tus nqi yog tsawg dua.

Tshwj xeeb tshaj yog cov tub ntxhais hluas, kev loj hlob zuj zus xav tau phosphorus, vim tias cov khoom no ua kom lub zog ntawm cov txheej txheem hauv cov hlwb thiab cov ntaub so ntswg. Thiab cov nroj tsuag tsis tuaj yeem tau txais los ntawm qhov chaw uas tsis yog los ntawm hauv av. Hmoov zoo, niaj hnub no muaj ntau ntau hom chiv nyob rau hauv khw muag khoom, ib qho ntawm uas tsuas yog tib ob npaug superphosphate.

Nws muaj dab tsi?

Yog li koj tuaj tom khw. Nco ntsoov tias muaj ntau hom superphosphate, tab sis ob chav superphosphate yog qhov koj xav tau. Nws cov formula yog Ca(H2PO4)2H2 O.

Nws muaj tsawg kawg yog 50% (+-5%) phosphorus. Ntxiv mus, nws yog nyob rau hauv ib qho yooj yim digestible daim ntawv rau tag nrho cov nroj tsuag. Tsis tas li ntawd, nws muaj 15% (+-2%) nitrogenous compounds, uas tseem tuaj yeem nqus tau los ntawm cov nroj tsuag. Peb yuav tsum tsis txhob hnov qab txog sulfur (6%). Tsis zoo li superphosphate yooj yim, nws tsis muaj gypsum. Qhov no txhais tau tias nws yuav siv tsis tau rau cov av deoxidation.

Cov chiv no muaj nyob rau hauv daim ntawv ntawm granules, zoo kawg nkaus soluble hauv dej. Nws yog ib qho tseem ceeb heev kom coj nws mus rau hauv av thaum ntxov caij nplooj ntoos hlav los yog lub caij nplooj zeeg (tom qab sau qoobsau qoob). Txwv tsis pub, phosphorus tsuas yog yuav tsis muaj sijhawm los faib rau hauv av. Tsis tas li ntawd, peb xav kom dej nrog kev daws ntawm superphosphate tag nrho cov nroj tsuag (tsawg kawg ob zaug hauv ib lub caij) uas tsis muaj phosphorus. Zoo li ntau lwm cov ntxhia chiv, nws tuaj yeem siv rau txhua qhov av.

Yuav ua li cas txhaj tshuaj?

Tsis zoo li ntau yam khoom, Ob chav superphosphote fertilizer tsis tas yuav tsum tau siv nruj me ntsis rau kev khawb cov av granules hla nws cov npoo hauv lub Hoobkas ntim. Txawm li cas los xij, nws qhov ntau npaum li cas nyob ntawm qhov tsis tsuas yog nyob ntawm hom cog qoob loo, tab sis kuj nyob ntawm cov yam ntxwv ntawm cov av nws tus kheej.

Yog li, agronomists pom zoo kom siv 30 mus rau 40 g ib square meter ntawm av yog tias koj npaj yuav cog zaub lossis tshuaj ntsuab ntawm qhov chaw no. Nyob rau hauv rooj plaub thaum koj lub vaj nyob rau ntawm qhov chaw nrog cov av tsis zoo, tus nqi ntawm cov chiv yuav tsum tau nce los ntawm kwv yees li 20-30%. Yog tias koj xav txhim kho qhov saj ntawm cov txiv hmab txiv ntoo, ces txog 500-600 g yuav tsum tau nchuav rau hauv ib tsob ntoo txiv hmab txiv ntoo hauv lub caij nplooj zeeg. Nws yog qhov yooj yim tshaj los ua qhov no thaum khawb lub cev lub voj voog. Txog 90-100 g yog nchuav rau hauv tsev cog khoom thiab tsev cog khoom, thiab thaum cog qos yaj ywm thiab lwm cov qoob loo nightshade, lawv muab 3-4 g rau ib qhov.

Nco ntsoov! Nyob rau hauv tsis muaj cov ntaub ntawv tsis pub tshaj qhov pom zoo koob tshuaj, raws li nyob rau hauv cov ntaub ntawv no, kub hnyiab ntawm cov nroj tsuag keeb kwm yog ua tau. Mineral chiv yog tshuaj lom neeg heev, yog li koj yuav tsum tsis txhob hnov qab txog nws.

Lwm yamCov lus pom zoo rau kev siv

Raws li peb tau hais, ob chav superphosphate yog qhov zoo rau kev siv rau txhua hom av thiab rau txhua yam nroj tsuag ua liaj ua teb. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov av pH txo qis heev tuaj yeem tiv thaiv nws cov kev sib cais, thiab yog li ntawd cov acidity yuav tsum tau txo ua ntej thov. Ua li no, thaum khawb, 200 g ntawm tshauv yuav tsum tau ntxiv. Xwb, koj tuaj yeem siv 500 grams ntawm txiv qaub ib square meter ntawm cheeb tsam.

Nco ntsoov! Muab ob npaug rau granular superphosphate yuav tsum tau siv tsuas yog ib hlis tom qab deoxidation, txwv tsis pub nws yuav luag tag nrho nws cov khoom muaj txiaj ntsig. Raws li peb tau hais lawm, nws tuaj yeem siv tsis tau tsuas yog thaum khawb, tab sis kuj tawg rau hauv ib txheej nyias ntawm cov av, lossis ntxiv rau txhua qhov.

Koj yuav tsum tau saib qhov kev faib ua feem ntawm lub pob, vim nws tuaj yeem sib txawv rau ntau hom nroj tsuag. Nws yuav tsum tsis txhob tov nrog txiv qaub, urea los yog chalk nyob rau hauv txhua rooj plaub, vim hais tias ntawm cov tshuaj tiv thaiv tsis tu ncua, cov chiv yuav luag tag nrho.

Tsis tas li, qhov no yuav ua rau cov khoom sib txuas uas yuav tsis muaj txiaj ntsig zoo rau koj cov nroj tsuag, yog li nws yog qhov zoo tshaj plaws tsis txhob sim.

Nws yog dab tsi?

Zoo li lwm hom pob zeb hauv av chiv, ob chav granular superphosphate (uas peb tau txiav txim siab) yog tau los ntawm cov pob txha ntawm cov tsiaj hauv tsev, nrog rau qee hom kev pab.pob txha. Hauv lwm cov txheej txheem ntuj tsim, tsuas yog tsis muaj qhov txaus ntawm phosphorus yooj yim digestible. Yog li, cov lus ntawm Academician Fersman hais txog phosphorus ua "biogenic mechanism ntawm lub neej thiab kev xav" tau lees paub tag nrho.
