Qhov sib txawv ntawm DAP thiab NPK Fertilizer

Qhov sib txawv tseem ceeb ntawm DAP thiab NPK chiv yog tias DAP chiv tsis muajpoov tshuajhos NPK chiv muaj poov tshuaj thiab.

DAP Fertilizer yog dab tsi?

DAP chiv yog qhov chaw ntawm nitrogen thiab phosphorous uas muaj kev siv dav hauv kev ua liaj ua teb.Qhov tseem ceeb ntawm cov chiv no yog diammonium phosphate uas muaj cov tshuaj formula (NH4) 2HPO4.Ntxiv mus, IUPAC lub npe ntawm cov tshuaj no yog diammonium hydrogen phosphate.Thiab nws yog dej-soluble ammonium phosphate.

Nyob rau hauv cov txheej txheem ntawm cov chiv no, peb hnov ​​​​mob phosphoric acid nrog ammonia, uas ua rau kub slurry uas yog ces txias, granulated thiab sieved kom tau cov chiv uas peb yuav siv tau nyob rau hauv lub teb.Ntxiv mus, peb yuav tsum tau ua nrog cov tshuaj tiv thaiv nyob rau hauv kev tswj xyuas, vim hais tias cov tshuaj tiv thaiv siv sulfuric acid, uas yog txaus ntshai los daws.Yog li ntawd, tus txheej txheem nutrient qib ntawm cov chiv no yog 18-46-0.Qhov no txhais tau tias, nws muaj nitrogen thiab phosphorous nyob rau hauv qhov ratio ntawm 18:46, tab sis nws tsis muaj poov tshuaj.

Feem ntau, peb xav tau kwv yees li 1.5 mus rau 2 tons ntawm phosphate pob zeb, 0.4 tons ntawm sulfur (S) kom yaj cov pob zeb, thiab 0.2 tons ntawm ammonia rau kev tsim DAP.Ntxiv mus, pH ntawm cov khoom no yog 7.5 txog 8.0.Yog li ntawd, yog tias peb ntxiv cov chiv no rau hauv av, nws tuaj yeem tsim cov alkaline pH nyob ib ncig ntawm cov chiv granules uas yaj hauv av dej;yog li tus neeg siv yuav tsum tsis txhob ntxiv ntau npaum li cas ntawm cov chiv no.

NPK Fertilizer yog dab tsi?

NPK chiv yog peb yam chiv uas muaj txiaj ntsig zoo rau kev ua liaj ua teb.Cov chiv no ua raws li qhov chaw ntawm nitrogen, phosphorus thiab potassium.Yog li ntawd, nws yog ib qho tseem ceeb ntawm tag nrho peb cov khoom noj tseem ceeb uas cov nroj tsuag xav tau rau nws txoj kev loj hlob, kev loj hlob thiab kev ua haujlwm zoo.Lub npe ntawm cov khoom no kuj qhia txog cov khoom noj uas nws tuaj yeem muab tau.

NPK kev ntsuam xyuas yog kev sib xyaw ntawm cov lej uas muab qhov sib piv ntawm nitrogen, phosphorous thiab potassium muab los ntawm cov chiv no.Nws yog ib qho ua ke ntawm peb tus lej, sib cais los ntawm ob lub dashes.Piv txwv li, 10-10-10 qhia tias cov chiv muab 10% ntawm txhua qhov khoom noj.Nyob ntawd, thawj tus lej hais txog qhov feem pua ​​​​ntawm nitrogen (N%), tus lej thib ob yog rau feem pua ​​​​phosphorous (hauv daim ntawv ntawm P2O5%), thiab qhov thib peb yog rau cov poov tshuaj feem pua ​​(K2O%).
