Diammonium Hydrogen Phosphate Fertilizer Kev muag khoom
Khoom: Diammonium Hydrogen Phosphate Fertilizer rau muag
Nqe lus piav qhia: DAP tau siv dav hauv kev ua liaj ua teb ua cov chiv nitrogen-phosphorus siab. Nws qhov sib npaug sib npaug ua rau nws tsim nyog rau kev txhawb nqa kev loj hlob ntawm cov nroj tsuag thiab txhawb cov qoob loo yields. Nws yog feem ntau siv rau ntau hom qoob loo, suav nrog cereals, txiv hmab txiv ntoo, zaub, thiab oilseeds.
a. Solubility: Diammonium hydrogen phosphate yog soluble hauv dej, ua rau nws yooj yim rau cov nroj tsuag thaum siv los ua chiv. Qhov kev solubility no kuj ua rau nws siv tau rau hauv cov kua formulations.
b. Qib pH: DAP feem ntau muaj me ntsis acidic pH, uas tuaj yeem pab hauv av acidification, yog tias xav tau, txhawm rau txhim kho cov zaub mov muaj rau cov nroj tsuag.
c. Cov ntsiab lus khoom noj: DAP yog ib qho zoo heev ntawm nitrogen thiab phosphorus, nrog rau cov ntsiab lus nitrogen feem ntau yog li ntawm 17 feem pua mus rau 21 feem pua thiab phosphorus cov ntsiab lus ntawm 44 feem pua rau 46 feem pua.
d. Kev sib xyaw ua ke: DAP tuaj yeem sib xyaw nrog lwm cov chiv thiab cov as-ham, tso cai rau cov qauv tsim kho raws li cov qoob loo tshwj xeeb thiab cov av xav tau.
