Lub luag haujlwm ntawm diammonium phosphate Cov tshuaj xwm ntawm diammonium phosphate yog alkaline, yog li nws yog rau alkaline fertilizer. Diammonium phosphate yog qhov ua haujlwm siab-ceev nrawm nitrogen thiab phosphorus compound fertilizer nrog phosphorus ua cov khoom tseem ceeb. Nws yog qhov tsim nyog rau feem ntau cov qoob loo thiab kuj tsim nyog siv nyob rau hauv ntau qhov av. Nws muaj ntau hom kev siv thiab tuaj yeem siv los ua cov hauv paus chiv los yog topdressing. tuaj yeem.
Daim ntawv thov ntawm diammonium phosphate Diammonium phosphate tuaj yeem siv los ua kom cov av ntawm ntau hom av hauv cov liaj teb thiab cov teb qhuav. Nws tsim nyog rau feem ntau cov qoob loo xws li mov, nplej, pob kws, qos qab zib, txiv laum huab xeeb, txhom tsoob, thiab txiv laum huab xeeb. Nws yog qhov tshwj xeeb tshaj yog rau cov qoob loo uas xav tau hydrogen thiab phosphorus xws li kab tsib thiab dej txiv ntseej. Diammonium phosphate tuaj yeem siv ua ke nrog ammonium bicarbonate, urea, ammonium chloride, potassium chloride, ammonium nitrate thiab lwm cov chiv. Zam kev sib xyaw ua ke daim ntawv thov nrog acidic chiv xws li ammonium sulfate thiab superphosphate. Cov nyhuv tom qab siv yog qhov zoo. Txhawb cog kev loj hlob cog.
Kev siv diammonium phosphate
1. Kev xyaum ua haujlwm tau ua pov thawj tias diammonium phosphate tuaj yeem siv tau rau ntau hom av hauv cov liaj teb thiab cov av qhuav, tsim nyog rau cov qoob loo feem ntau xws li mov, nplej, pob kws, qos yaj ywm, txiv laum huab xeeb, txhom tsoob, txiv laum huab xeeb, thiab lwm yam. hydrogen-phosphorus xav tau cov qoob loo xws li kab tsib thiab dej txiv ntseej.
2. Diammonium phosphate tuaj yeem siv ua ke nrog ammonium bicarbonate, urea, ammonium chloride, potassium chloride, ammonium nitrate thiab lwm cov chiv. Zam kev sib xyaw ua ke daim ntawv thov nrog acidic chiv xws li ammonium sulfate thiab superphosphate.
3. Kev sim qhia tau hais tias diammonium phosphate ua ke nrog nitrogen thiab potassium chiv (chlorine-muaj chiv yuav tsum tsis txhob siv cov tshuaj chlorine tsis muaj qoob) yog qhov tsim nyog rau cov qoob loo siv basal fertilizer, nrog rau kev siv ntau npaum li 225 ～ 300kg / h㎡; thov rau hauv liaj teb: Tom qab tig lub laij, thov nws mus rau txheej dej ntiav; Daim ntawv thov av qhuav: daim ntawv thov sib sib zog nqus thaum plowing thiab sib txuas, sib xyaw av hauv av. Sib tov diammonium phosphate thiab decomposed organic chiv nrog nruab nrab pH thiab thov tom qab kev zom, cov chiv ua tau zoo. Thaum ua cov noob tso rau, nws yuav tsum thov 1 mus rau 2 hnub ua ntej tseb, ntau npaum 100-150kg / h㎡, thiab cov av hauv cov av yog sib xyaw kom tsis txhob sib xyaw ntawm cov noob thiab chiv.
4. Rau kev tsim cov tshuaj nrog aqueous tov ntawm diammonium phosphate, diammonium phosphate (nitrogen thiab potassium fertilizer nyob ntawm hom qoob loo) yuav tsum tau yaj nyob rau hauv dej ntawm qhov sib piv ntawm 1: 5 ntawm chav sov hauv thaj chaw ze ntawm qhov chaw ua tiav ntawm 1 txog 2 hnub ua ntej fertilization. Tom qab ua kom tiav, coj cov tshuaj tov dej thiab ua kom nws nrog dej ntawm 1: 25-30, lossis siv biogas kua ua kua kom yaj, thiab qhov ntau ntawm cov tshuaj chiv nrog dej yog 60-80 zaug. Qhov kev cog lus fertilization yuav tsum tau sib zog rau hauv cov theem ntawm cov noob qoob loo lossis thaum cov av qhuav; qhov kev cog qoob loo ua tau tsim nyog tau nce ntxiv thaum tus neeg laus cog theem thiab cov av noo noo.
Cov tshuaj thaiv tsis haum rau kev siv diammonium phosphate Diammonium phosphate muaj ntau dua phosphate ions.After fertilizing cov nroj tsuag, nws yuav nce acidity ntawm cov av rau ntawm cov av acidic, uas yuav cuam tshuam rau kev loj hlob ntawm cov nroj tsuag. Ceev faj tsis txhob siv nws li kev hnav khaub ncaws sab saum toj. Kis cov granular diammonium phosphate nyob rau saum npoo, hauv paus system yuav tsis nqus nws, thiab cov nyhuv chiv yuav ploj. Zam kev sib xyaw nrog cov tshuaj acidic, xws li ammonium sulfate, superphosphate, thiab lwm yam, uas yuav ua rau ntau acidic thiab ua rau cuam tshuam.
