Lub npe phosphorus chiv. Fertilizer nrog phosphorus yog cov khoom noj tseem ceeb. Qhov loj thiab ceev ntawm cov nyhuv chiv yog txiav txim siab los ntawm cov ntsiab lus phosphorus pentoxide zoo, cov khoom hauv av, kev siv chiv, thiab hom qoob loo.
1. Kev faib tawm los ntawm qhov chaw
Raws li qhov chaw tuaj yeem muab faib ua:
(1) Ntuj phosphate chiv, xws li guano, tsiaj pob txha noj mov thiab ntses pob txha noj mov.
(2) Cov tshuaj phosphate chiv, xws li calcium superphosphate, ob chav superphosphate, calcium magnesium phosphate fertilizer, phosphate pob zeb hmoov, thiab lwm yam.
2. Muab faib raws li qhov solubility ntawm phosphate muaj
(1) Dej-soluble phosphate chiv, xws li zoo tib yam calcium superphosphate, ob chav superphosphate, thiab lwm yam. Nws cov khoom tseem ceeb yog monocalcium phosphate. Soluble nyob rau hauv dej, ceev fertilizer nyhuv.
(2) Lycium soluble phosphate chiv, xws li precipitated phosphate chiv, steel slag phosphate chiv, calcium magnesium phosphate chiv, defluorinated phosphate chiv, thiab lwm yam. Nws cov khoom tseem ceeb yog dicalcium phosphate. Me ntsis soluble nyob rau hauv dej tab sis soluble nyob rau hauv 2 feem pua citric acid tov, cov chiv nyhuv qeeb.
(3) Insoluble phosphate chiv, xws li pob txha noj mov thiab phosphate pob zeb hmoov. Nws cov khoom tseem ceeb yog tricalcium phosphate. Nws yog me ntsis soluble hauv dej thiab 2 feem pua citric acid daws, thiab tsuas yog tuaj yeem tsim cov nyhuv chiv tom qab maj mam hloov mus rau hauv monocalcium phosphate lossis dicalcium phosphate hauv av.
3. Kev faib tawm los ntawm kev tsim khoom
Raws li txoj kev tsim khoom, nws tuaj yeem muab faib ua phosphate fertilizer thiab thermal phosphate fertilizer.
Kev siv cov phosphorus chiv tsim nyog tuaj yeem txhawb nqa tillering thiab ntxov kom loj hlob ntawm cov qoob loo, txhim kho lawv qhov txias, thiab txhim kho lawv cov txiaj ntsig thiab zoo.
Phosphate fertilizer yog cov tshuaj chiv uas muaj cov qoob loo zoo phosphorus tsim los ntawm phosphate pob zeb.
Phosphorus yog ib feem ntawm cell protoplasm hauv cov nroj tsuag thiab ua lub luag haujlwm tseem ceeb hauv kev loj hlob ntawm tes thiab kev loj hlob; phosphorus tseem koom nrog hauv photosynthesis hauv cov nroj tsuag lub neej, kev siv cov piam thaj thiab cov hmoov txhuv nplej siab, thiab hloov lub zog.
Phosphorus chiv kuj tseem tuaj yeem txhawb kev loj hlob ntawm cov hauv paus system ntawm cov nroj tsuag ntawm cov yub theem thiab ua rau cov nroj tsuag paub tab ntxov. Thaum cov nroj tsuag dais txiv hmab txiv ntoo, ib tug loj npaum li cas ntawm phosphorus yog pauv mus rau lub noob, ua rau cov noob plump.
Qhov ntxov tshaj plaws phosphate chiv yog superphosphate, uas tau maj mam hloov los ntawm high-concentration phosphate chiv xws li ammonium phosphate thiab ob superphosphate.
Qib ntawm cov khoom siv zoo ntawm phosphate fertilizer yog qhia los ntawm qhov loj feem ntawm phosphorus pentoxide.
Kev txheeb xyuas qhov zoo ntawm nitrogen, phosphorus thiab potassium chiv hom Ua ntej, phosphorus chiv tuaj yeem paub qhov txawv ntawm nitrogen thiab potassium chiv nyob rau hauv cov nqe lus ntawm cov tsos thiab solubility. Feem ntau siv nitrogen thiab poov tshuaj chiv feem ntau yog cov muaju dawb (ntsuas poov tshuaj chloride feem ntau reddish, txiv qaub nitrogen dub), thiab soluble hauv dej. Feem ntau siv phosphate chiv yog grey hmoov, insoluble los yog ib nrab soluble hauv dej. Yog tias koj xav paub qhov txawv ntawm nitrogen thiab poov tshuaj chiv ntxiv, koj tuaj yeem zom cov chiv rau hauv cov hmoov, noj me me thiab hlawv rau ntawm daim hlau me me. Yog tias nws tuaj yeem hlawv, nws yuav yaj lossis tawm cov pa luam yeeb dawb li nitrogen chiv; Yog tias nws tsis hlawv, tab sis dhia lossis tawg, nws yog Potassium chiv, kom deb li deb koj tuaj yeem paub qhov txawv ntawm nitrogen chiv, phosphorus chiv, thiab poov tshuaj chiv.
