Humic Acid Muaj nuj nqi thiab Ua Haujlwm

Xi'an Naturetech Co., Ltd | Updated: Oct 26, 2017

Humic acid yog sib tov ntawm cov organic organic macromolecular tebchaw. Nruab nrab ntawm cov av qeeg hauv cov av yog qhov loj tshaj plaws, av humic acid yog physicochemical heterogeneous txoj sib tov ntawm molecular luj yog polydisperse, sib tov yog ntuj, siab molecular phaus, daj rau dub, Amorphous, colloidal, rog thiab aromatic organic polyelectrolyte muaj pes tsawg leeg, tsis tuaj yeem siv ib cov qauv siv tshuaj.

Qhov twg tsis humic acid tuaj?

1, av humic acid yug, feem ntau yog cov nroj tsuag nyob rau hauv qhov kev txiav txim ntawm microorganisms nyob rau hauv tsim ntawm ib chav kawm ntawm tshwj xeeb macromolecule organic compounds sib tov.

2, thee humic acid yog lub microbial decomposition thiab transformation ntawm cov nroj tsuag, tab sis kuj tom qab mus sij hawm ntev geological thiab tshuaj, thiab tsim muaj ib chav kawm ntawm cov sib xyaw organic sib xyaw organic sib xyaw.

Humic Acid Structure Ua Haujlwm thiab Kev Ua Haujlwm

1, qauv

Humic acid yog ib chav kawm ntawm cov organic organic qaug cov kua qoob loo, muaj li ntawm fulvic acid, dub fulvic acid thiab xim av peb lub cev.

2, qhov muaj pes tsawg leeg ntawm cov ntsiab lus

Coal humic acid thiab av organic teeb meem nyob rau hauv humic acid muaj ib tug zoo sib xws thiab qhov ntawm ntsiab ntsiab lus ntawm humic acid carbon, hydrogen, oxygen, muaj ib tug me me ntawm nitrogen thiab sulfur, ntxiv rau ntau yam kev ua haujlwm pawg.

3, lub luag hauj lwm ntawm humic acid

Cov av organic yog feem ntau saum av qeeg, cov qia kua qaub nyob hauv corrosive acid yog lub cev lub cev thiab nws txoj kev sib xyaw nrog cov xaim hlau, humic acid yog tus tshaj plaws thiab zoo tshaj plaws ntawm cov organic teeb meem.

(1) qhov ncaj cov nyhuv ntawm humic acid

Txhawb cog kev loj hlob thiab nce qoob loo.

(2) indirect effect

Lub luag haujlwm ntawm lub cev

A. Txhim kho av av. B. Kev tiv thaiv ntawm av tawg thiab yaig. C. nce cov dej av uas muaj peev xwm tuav, ua kom txias txias. D. ua cov xim av ib tsos tsaus tsawv, yog qhov ua kom lub zog hnub ci zog.

② tshuaj lom neeg. A. Kho cov av pH. B. Txhim kho thiab optimize cog kev haum ntawm cov as-ham thiab dej. C. nce cov av tsis tuaj yeem ua haujlwm. D. Nyob rau hauv alkaline cov neeg mob, yog ib tug neeg sawv cev ntuj tsim (chelated nrog hlau ions, txhawb lub nqus ntawm cov nroj tsuag). E. Muaj nplua nuj nyob rau hauv cov organic teeb meem thiab cov zaub mov tsim nyog rau kev loj hlob ntawm cov nroj tsuag. F. Txhim kho qhov teeb meem ntawm cov organic chiv thiab txo qhov poob ntawm fertilizer. G. Lub cev nutrient hloov dua siab tshiab rau hauv lub xeev yooj yim absorbed los ntawm cov nroj tsuag. H. tuaj yeem ua kom lub cev muaj nitrogen tsawg, txo cov phosphorus immobilization, muaj peev xwm nkag mus rau cov av hauv nitrogen, phosphorus thiab potassium thiab lwm yam, tiv thaiv lub thawv khaws cia hauv av, thiab tuaj yeem ua tus txheej txheem ntawm cov cev, daim ntawv thov ntawm inorganic fertilizer Yog li, humic acid yog "cia" rau cov nroj tsuag as-ham thiab cov khoom muaj sia muaj sia.

③ muaj teeb meem lom

A. tsa txoj kev loj hlob thiab kev luam tawm ntawm kev microbes nyob rau hauv cov av. B. txhawm rau txhim kho cov kab mob nroj tsuag uas tsis muaj zog, kab tsis ua hauj lwm.

Qeb plaub, feem ntau yog siv cov tshuaj humic acid thiab yam ntxwv

Nyob rau ntawm tam sim no, humic acid feem ntau siv raws li fertilizer faib rau lignite humic acid, weathered thee humic acid, peat (grassland humic acid).

1, lignite humic acid yog theem thib ob ntawm cov txheej txheem ntawm cov roj (diagenetic) cov khoom, rau qhov iab theem tsis muaj humic acid, lignite humic acid nyob rau hauv cov ntsiab lus ntawm 1-85%, xim av xim av xim av, dub, raws li rau qhov tob tau muab faib ua

(1) av lignite: cov degree ntawm coalification yog ntiav, cov ntsiab lus qes, cov ntsiab lus humic acid siab dua, feem ntau tshaj 40%.

(2) cov xim ci xim av: qhov tob tob ntawm cov xim, cov ntsiab lus ntawm cov pa roj carbon dioxide ntau, cov ntsiab lus humic acid tsawg, feem ntau 1-10%.

(3) ntom ntom lignite: nruab nrab ntawm (1) thiab (2) ntawm cov ntsiab lus humic acid ntawm li ntawm 30%.

2, weathered coal humic acid uas tawm hauv cov av, feem ntau hu ua Johnson. Feem ntau nyob ze los yog raug rau cov nplais ntawm cov lignite, bituminous thee, anthracite, los ntawm huab cua, hnub ci, los nag thiab daus, xuab zeb, khov thiab lwm yam infiltration ntawm weathering, thiab tsim ntawm cov khoom. Humic acid uas ua los ntawm cov txheej txheem no yog weathering coal humic acid, kuj hu ua natural regenerated humic acid, cov ntsiab lus humic acid nyob rau hauv cov hluav taws xob cov hluav taws xob, xws li 5-80%.

3, peat (peat, peat, lwm yam) humic acid

Peat yog thawj theem ntawm cov roj tsim, kuj hu ua peat, Suav peat humic acid cov ntsiab lus nyob rau hauv 20-40%. Peat nyob rau hauv cov organic teeb meem, tsis yog decomposed los ntawm cov nroj tsuag pov tseg thiab humic acid nyob tus yeees, Suav peat humic acid ntsiab lus ntawm 20-40%.
