Qhov sib txawv tseem ceeb ntawm phosphate solubilizing thiab phosphate mobilizing yog tias phosphate solubilizing microorganisms hydrolyze organic thiab inorganic insoluble phosphorus tebchaw rau soluble phosphorus thaum phosphate mobilizing microorganisms mobilize insoluble thiab tsau cov ntxhia hauv cov ntaub ntawv ntawm phosphorus.
Phosphorus yog ib qho tseem ceeb ntawm cov nroj tsuag cov as-ham. Nws yog qhov thib ob tsuas yog nitrogen thiab suav tias yog ib qho ntawm cov kev loj hlob tshaj plaws-txhim kho macronutrients ntawm cov nroj tsuag. Av yog nplua nuj nyob rau hauv insoluble phosphates. Tab sis nws yog deficiency nyob rau hauv soluble phosphates, uas yuav absorbed los ntawm cov nroj tsuag. Cov nroj tsuag nqus phosphorus nyob rau hauv daim ntawv ntawm orthophosphate. Phosphorus deficiency ua rau cov nroj tsuag loj hlob, kev loj hlob, thiab tawm los. Txhawm rau kov yeej P scarcity hauv cov av ua liaj ua teb, phosphorus chiv ntxiv. Qhov tseeb, phosphorus yog qhov thib ob feem ntau siv cov khoom noj hauv kev ua liaj ua teb. Av microorganisms ua lub luag haujlwm tseem ceeb hauv P cycling thiab phosphorus khoom noj khoom haus ntawm cov nroj tsuag. Qee cov kab mob koom nrog hauv cov ntxhia phosphate solubilization thiab pab txhawb phosphate mobilization hauv av.
Y Phosphate Solubilizing yog dab tsi?
Phosphate solubilizing microorganisms yog cov microbes uas muaj mineralization thiab solubilization muaj peev xwm rau cov organic thiab inorganic phosphorus, feem. Phosphorus solubilizing kev ua si yog txiav txim siab los ntawm lub peev xwm ntawm microbes tso tawm metabolites xws li cov organic acids, los ntawm lawv cov hydroxyl thiab carboxyl pawg chelate cov cation khi rau phosphate, tom kawg tau hloov mus rau cov ntawv soluble.
Phosphate solubilization tshwm sim los ntawm ntau yam microbial txheej txheem / txheej txheem, suav nrog cov organic acid ntau lawm thiab proton extrusion. Ntau yam ntawm microbial P solubilization mechanisms muaj nyob rau hauv qhov xwm txheej, thiab ntau lub ntiaj teb kev voj voog ntawm insoluble organic thiab inorganic av phosphates yog ntaus nqi rau cov kab mob thiab cov fungi. Phosphorus solubilization yog nqa tawm los ntawm ntau cov kab mob saprophytic thiab fungi ua rau cov av soluble phosphates sparingly. Ntawm cov kab mob sib txawv, kab mob los ntawm genera Bacillus, Pseudomonas, thiab Rhizobium, fungal hom los ntawm genera Penicillium thiab Aspergillus, actinomycetes, thiab arbuscular mycorrhizae yog nrov phosphate solubilizing microbes inhabiting av.
Daim duab 01: Clear Halo Production by PSM
Phosphate solubilizing microorganisms raug cais tawm thiab cim ntawm qhov nruab nrab hu ua Pikovaskaya's (PVK) nruab nrab. Qhov nruab nrab no muaj insoluble tricalcium phosphate (TCP) / hydroxyapatite ua ib qho P. Phosphate solubilising microorganisms ua kom pom tseeb halo nyob ib ncig ntawm lawv cov cheeb tsam. Lub peev xwm ntawm phosphate solubilising microbes solubilize insoluble phosphates nyob rau hauv cov av yog ib tug zoo attribute nyob rau hauv kev loj hlob ntawm biofertilizers rau kev ua liaj ua teb li. Yog li, lawv tau siv dav hauv biofertilizers hauv kev coj ua agronomic txij li thaum lawv ua lub luag haujlwm tseem ceeb los tshem tawm cov phosphorous deficiency ntawm cov av nyob rau hauv ib puag ncig tus phooj ywg, nqi-zoo thiab ruaj khov dua li tshuaj chiv.
Phosphate Mobilizing yog dab tsi?
Phosphate mobilizing microorganisms yog cov microbes uas koom nrog kev tsim cov phosphorus hauv av. Feem ntau ntawm phosphate mobilizing microbes yog phosphate solubilizing microorganisms. Lawv tso phosphorus los ntawm cov insoluble thiab tsau cov ntaub ntawv ntawm phosphorus nyob rau hauv cov av. Raws li qhov tshwm sim, av P muaj qhov nce ntxiv thiab cov nroj tsuag muaj peev xwm nqus tau phosphorus kom ruaj khov.
Daim duab 02: Phosphorus Cycle
Phosphate mobilizing microbes mob phosphorus los ntawm kev hloov pH thiab tseem los ntawm kev tsim cov tshuaj chelating. Cov ntsiab lus phosphate solubilizing thiab phosphate mobilizing yog interchangeably siv los xa mus rau phosphate solubilizing microorganisms. Phosphate mobilizing microbes koom nrog hauv kev hloov pauv ntawm cov av P.
Dab tsi zoo sib xws ntawm Phosphate Solubilizing thiab Phosphate Mobilizing?
- Kev siv phosphate solubilizing thiab phosphate mobilizing microorganisms yog ib qho kev cog lus rau kev txhim kho P fertilization efficiency hauv kev ua liaj ua teb.
- Feem ntau ntawm phosphate mobilizing microbes yog phosphate solubilizing microbes.
- Ob hom kab mob ua haujlwm hauv av thiab ua kom muaj P muaj nyob hauv av.
Qhov txawv ntawm Phosphate Solubilizing thiab Phosphate Mobilizing yog dab tsi?
Qhov sib txawv tseem ceeb ntawm phosphate solubilizing thiab phosphate mobilizing yog tias phosphate solubilizing microorganisms hydrolyze organic thiab inorganic insoluble phosphorus tebchaw rau soluble phosphorus thaum phosphate mobilizing microorganisms mobilize insoluble thiab tsau cov ntxhia hauv cov ntaub ntawv ntawm phosphorus.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm phosphate solubilizing thiab phosphate mobilizing.
Summary – Phosphate Solubilizing vs Phosphate Mobilizing
Qhov sib txawv tseem ceeb ntawm phosphate solubilizing thiab phosphate mobilizing yog tias phosphate solubilizing microorganisms hydrolyze organic thiab inorganic insoluble phosphorus tebchaw rau soluble phosphorus thaum phosphate mobilizing microorganisms mobilize insoluble thiab tsau cov ntaub ntawv ntawm phosphorus hauv av.
