Phosphorite hmoov yog dav cog rau hauv av ua ntej cog. Kev ua tau zoo ntawm nws qhov kev ua tau raug sau tseg ntawm cov av acidic, vim tias cov av muaj pes tsawg leeg cuam tshuam rau qhov decomposition ntawm phosphorus mus rau lub xeev uas cov nroj tsuag sai sai assimilate. Nov yog txoj hauv kev rau cov noob qoob loo yam tsis muaj kev zam.
Phosphorite hmoov tuaj rau cov neeg siv khoom hauv daim ntawv xim av lossis greyish hmoov, nws tsis muaj ntxhiab tsw, nws yog xyaum insoluble hauv dej. Qhov zoo ntawm cov cuab yeej no yog tias nws muaj lub sijhawm ntev ntawm kev ua haujlwm zoo. Nws yog siv los ua cov chiv tseem ceeb rau plowing thiab rau kev npaj ntawm composts raws li peat thiab manure. Txij li thaum phosphates yog me ntsis soluble hauv dej, cov chiv yog absorbed los ntawm cov nroj tsuag tsuas yog nyob rau hauv acidic av. Hauv cov av zoo li no, phosphate pob zeb (formula Ca3(PO4)2) hloov mus ua dihydrogen. phosphate.
Production
Phosphorites, uas yog lub hauv paus ntawm chiv, pw hauv txheej hauv av. Lawv tau mined ua ke nrog av nplaum, xuab zeb thiab lwm yam roob pob zeb.caj ces. Feem ntau, ntxiv rau phosphorites, calcites, apatites thiab silica pom. Nyob rau hauv cov ntaub ntawv no, lawv tau mined nyob rau hauv parallel, thiab ua cov nroj tsuag nyob ze ntawm qhov chaw mining.
Fertilizer yog tau los ntawm kev ntxuav phosphorites los ntawm cov xuab zeb thiab av nplaum, tom qab ntawd crushing rau hauv pieces thiab sib tsoo. Qhov no yog li cas phosphate pob zeb yog tsim. Cov muaj pes tsawg leeg ntawm cov chiv muaj xws li quartz, calcium, gypsum thiab siderite.
Fertilizer yog kho zoo los ntawm lub ntiaj teb thiab tseem nyob qhov twg nws ntxiv. Thiab qhov no txhais tau hais tias thaum lub sij hawm dej, cov khoom tsis nkag mus tob rau hauv thiab tsis ntxuav tawm ntawm cov av. Ua ntej sowing, phosphorite hmoov yog siv tob rau hauv av noo, mus rau hauv paus system ntawm cov nroj tsuag. Qhov no yog vim qhov qis qis ntawm phosphorus: qhov ze nws mus rau hauv cov hauv paus hniav, nws qhov kev ua tau zoo dua.
Thaum lub sijhawm siv cov chiv ntiav ntiav, ib feem ntawm nws tseem nyob ntawm qhov chaw, dries sai, uas ua rau cov hauv paus hniav tuag. Yog li ntawd, qhov chaw pub mis tsis muaj kev sib sib zog nqus sib sib zog nqus yog tsis muaj txiaj ntsig. Qhov siab dua qhov sib tsoo ntawm hmoov, qhov zoo dua qhov decomposition ntawm phosphorus nyob rau hauv lub zog ntawm av acid thiab yooj yim dua nws absorbed los ntawm cov nroj tsuag.
Phosphorus yog ib qho ntawm cov kab tseem ceeb tsim nyog rau kev tsim cov hauv paus hniav, kev loj hlob ntawm cov nroj tsuag thiab cov noob maturation. Nws tswj cov txheej txheem metabolic thiab muab lub zog tsim nyog, ua qhov tseem ceeb ntawm cov khoom noj khoom haus. Qee cov nroj tsuag xav tau ntau npaum li cas ntawm phosphorus, lwm tus tsawg dua. Tab sis ib yam yog qhov tseeb: tsis muaj cov khoom no, tsob ntoo lub neej nres.
Ib qho tseem ceeb: siv rau hauv av ntau dhau, phosphate pob zeb yuav tsis ua rau muaj kev phom sij,fertilizer yog absorbed nyob rau hauv qhov yuav tsum tau ntim thiab pab txo qhov teeb meem los ntawm acidic av. Cov chiv tau pom nws cov txiaj ntsig zoo vim nws siv rau ntawm cov av soddy-podzolic, swampy thiab alkaline chernozems.
Tsis muaj phosphorus cuam tshuam cov nroj tsuag tsis zoo tshaj plaws. Lawv txoj kev loj hlob qeeb zuj zus, cov hauv paus hniav tsis zoo.
Cov cim qhia ntawm phosphorus deficiency
Yog tias koj paub cov tsos mob ntawm qhov tsis txaus ntawm cov as-ham, lawv tuaj yeem ntxiv sai sai. Phosphorus deficiency nyob rau hauv lub ntiaj teb yog manifested nyob rau hauv cov nram no:
- Nroj tsuag hloov xim rau ntsuab tsaus lossis ntshav.
- Hloov cov nplooj, lawv poob ua ntej.
- Cov nplooj hauv qab yog npog nrog cov pob tsaus.
- tsob ntoo tsis loj hlob thiab pib tawg.
- Npau suav tsis zoo ua rau tsob ntoo poob hauv av.
Ua rau phosphorus tshaib plab hauv cov nroj tsuag
Cov cim qhia no yooj yim tshem tawm yog tias phosphorus hmoov ntxiv rau lub sijhawm. Ua rau ntawm phosphorus tsis muaj xws li:
- Kev hloov pauv ntawm phosphorus rau hauv cov ntawv tsis txaus.
- Txhob muab chiv tsis raug.
- Av depletion los ntawm kev siv av.
- Tshem tawm cov phosphorus nrog cov qoob loo yam tsis muaj nws ntxiv tom ntej.
- Cov av yog cog nrog inorganics.
Zoo zoo
- Kev sib ntxiv ntawm phosphorus pab nce yields.
- Tshuaj tiv thaiv kab mob.
- Tshwj xeeb nce % qab zib cov ntsiab lus ntawm cov hauv paus qoob loo.
- Saturates cov nroj tsuag nrog cov ntsiab lus tseem ceeb.
- Slows down time harvest.
- Txhawb kev tiv thaiv Frost, drought lossis noo noo.
- Txo cov leaching ntawm cov khoom muaj txiaj ntsig los ntawm cov av.
Phosphorite hmoov, cov khoom uas tau tham saum toj no, tsis nqus dej noo. Thaum lub sijhawm khaws cia ntev, nws tsis plam nws cov yam ntxwv: nws tsis yaj hauv dej, tsis tawm toxins, tsis tawg, tab sis plua plav heev.
Qeb ntawm phosphorite chiv
Phosphorite chiv coj txawv nrog dej, yog li lawv muab faib ua:
- Fertilizers soluble heev. Lawv suav nrog kev hnav khaub ncaws thoob ntiaj teb, thiab lawv raug pom zoo kom siv rau cov av acidic thiab alkaline.
- Fertilizers sparingly soluble. Cov no suav nrog phosphorus thiab pob txha noj mov, siv rau hauv cov av acidic thiab grey-tsob hav zoov. Cov nroj tsuag yuav muaj peev xwm tau phosphorus tom qab raug rau cov acidity ntawm cov av los yog cov kua qaub secreted los ntawm cov hauv paus hniav.
Phosphorite hmoov yog sib npaug ntawm cov av thiab tom qab ntawd khawb, raws li kev suav ntawm 30 kg ib puas square metres ntawm thaj av. Qhov no yog qhov zoo tshaj plaws ua rau lub caij nplooj ntoos hlav, ua ntej cog. Ntxiv hmoov nplej thiab slaked txiv qaub tib lub sij hawm tsis pom zoo.
Crushed phosmuka, poob rau hauv av, yog yooj yim absorbed los ntawm cov nroj tsuag. Qhov zoo dua nws yog tov nrog cov av, qhov zoo dua ntawm kev siv.
Ib puag ncig tus phooj ywg phosphate pob zeb. Nws siv tsis ua rauav thiab dej nrog toxins. Nws tsis ua txhaum kev sib npaug ntawm ecological, thiab qhov no yog nws qhov tseem ceeb ntawm cov dej-soluble chiv.
pob txha noj
Thaum rho tawm phosphorus los ntawm cov organic tebchaw ntawm lub hauv paus chiv keeb, cov pob txha noj mov tau txais. Ua los ntawm cov pob txha nyuj rov ua dua tshiab, cov chiv no nquag siv rau txhua yam kev cog qoob loo. Ntxiv nrog rau phosphorus, pob txha noj mov kuj yog ib qho chaw ntawm nitrogen thiab calcium thiab yog qhov zoo tagnrho rau kev pub cov qoob loo xws li qos yaj ywm, txiv lws suav thiab dib.
Txhim kho thiab loj hlob hauv tsev paj, cov pob txha noj mov feem ntau siv ntau dua li cov khoom siv phosphorus kim. Nws cov txiaj ntsig zoo rau cov nroj tsuag loj hlob hauv ib lub tub yog tshwj xeeb tshaj yog pom. Nws yuav tsum tau nco ntsoov hais tias compost, peat los yog quav nyab yog siv nyob rau hauv kilograms, pob txha noj mov yuav tsum tau xam nyob rau hauv grams los yog diav.
Grass Fertilizer
Xwm nws tus kheej ua rau cov neeg ua teb npaj phosphorite chiv los ntawm cov nroj tsuag. Raws li lub hauv paus, cov tshuaj ntsuab tau noj uas muaj nitrogen ntau. Ntxiv cov nroj tsuag no tsuas yog txhim kho thiab ntxiv dag zog rau cov nplooj lwg. Ntuj phosphate chiv muaj xws li cov nroj tsuag hauv qab no: rowan txiv hmab txiv ntoo, hawthorn, wormwood, thyme thiab feather nyom. Los ntawm kev siv cov tshuaj ntsuab no, koj tuaj yeem tau txais cov khoom noj muaj txiaj ntsig zoo yam tsis tau ntxiv tshuaj chiv.
ntsuas kev nyab xeeb
Phosphorite hmoov tsis muaj tshuaj lom, muaj kev phom sij 4. Tab sis thaum ua haujlwm nrog nws, koj xav tauhnav ib lub tshuab ua pa thiab ib lub tsho tiv thaiv kom tsis txhob muaj hmoov nplej nkag mus rau hauv txoj kev ua pa. Yog tias nws nkag mus rau hauv qhov ntswg thiab qhov muag, lawv yuav tsum tau muab yaug nrog dej thiab tawm hauv qhov chaw kho mob.
Phosphorus-enriched av yog qhov tshwj tsis yog qhov tseeb. Tab sis ua tsaug rau lub systematic ntxiv ntawm chiv, tus nqi ntawm phosphorus yuav tsum tau rau ib txwm loj hlob thiab maturation ntawm cov nroj tsuag accumulates. Yog li ntawd, nws tsis tas yuav ua rau nws ib xyoos ib zaug, ib zaug txhua peb mus rau plaub xyoos yog txaus. Kev hnav khaub ncaws sab saum toj raws sijhawm yuav pab sau qoob loo tsim nyog ntawm koj tus kheej ua haujlwm.
