Ammonium sulfate chiv - pantry nitrogen thiab leej faj

Ammonium sulfate yog ib tug hluavtaws nitrogen-leej faj chiv, uas muaj 24% cov leej faj thiab 21% nitrogen. Externally nws tsa cov dawb crystalline ntsev uas yog zoo soluble nyob rau hauv cov dej thiab yog sib nruab nrab. Ammonium sulfate muaj ib tug uas tsis muaj hygroscopicity thiab ntev lub sij hawm cia nws tsis khoom qab zib, thaum ua kom cov flowability. Thiab tus nqi ntawm cov tshuaj muaj nyob rau hauv nws, yog ib qho nyuaj rau overestimate. Cov tib nitrogen muaj ib tug tseem ceeb feem ntawm lub neej ntawm cov nroj tsuag. Nws yog suav tias yog ib tug thawj coj ntawm cov chiv. Thiab leej faj nyob rau hauv kev txiav txim ntawm tseem ceeb rau tsob nroj noj qab haus huv yuav muab mus rau lub thib peb qhov chaw, txij thaum lub thib ob yuav siv sij hawm phosphorus.

Ammonium sulphate - chiv, uas daim ntawv thov no pab tau rau tag nrho cov hom ntawm cov qoob loo. Nws muaj tsis muaj teeb meem nyob rau hauv ua soluble nyob rau hauv cov dej, thiab ces zoo absorbed los ntawm cov nroj tsuag. Nyob rau hauv tas li ntawd, nws yog tsaug zog, thiab txawm nyob rau hauv siab dej yog tsis ntxuav tawm ntawm cov av. Tab sis cov hauj lwm zoo ntawm no chiv yog tsis qis tshaj li uas ntawm urea thiab ammonium nitrate. Tab sis yog hais tias peb xav txog ib co ntawm nws lub cev-tshuaj zog (flammability, tawg, neslezhivaemost) thiab tus nqi ntawm cov ammonium sulfate yuav tsum tau ntau npaum li cas dej siab rau lawv "rivals". Nws tseem yog ib qho tseem ceeb tivthaiv ntawm no chiv yog leej faj, uas plays ib qho tseem ceeb luag hauj lwm nyob rau hauv lub neej ntawm cov nroj tsuag. Nws yog ib feem ntawm cov protein thiab qhov tseem ceeb cov amino acids xws li methionine thiab cystine. nws tseem yog tam sim no nyob rau hauv cov vitamins thiab roj.

Nyob rau hauv no hais txog, ammonium sulphate muaj ib tug zoo ntxim rau cov redox dab tshwm sim nyob rau hauv cov nroj tsuag, raws li zoo raws li qhov ua kom ntawm enzymes thiab protein metabolism, lub pib khoom siv rau lub synthesis ntawm cov uas yog cia li oxidized daim ntawv ntawm sulfur. Thiab yog hais tias nws yog uas ploj lawm, ces protein synthesis yog ncua, thiab nyob rau hauv cov nroj tsuag yuav pib lub thiaj li hu ua leej faj starvation, uas nyob rau hauv lawv cov yam ntxwv reminiscent ntawm nitrogen starvation. Nyob rau tib lub cov qoob loo yog tshem tawm nyob rau hauv txoj kev loj hlob, lawv muaj elongated stems thiab nplooj yog txo. Txawm li cas los, lub tom kawg tsis tuag, tab sis coj ib tug daj ntseg xim. Thiab cov kev tshawb fawb pom tau hais tias nws yog leej faj tsis muaj peev xwm ua rau teeb ntawm nitrogen metabolism. Thiab nws yuav zam tau yog hais tias tus ntxiv ammonium sulfate. Fertilizer uas yuav pab restore lub tsis muaj sulfur.

Farmers kuj paub tias ntev li siv nitrogen chiv yuav ua tau kom ib puag ncig muaj teeb meem, tshwj xeeb tshaj yog yog hais tias koj tsis tus balanced as-ham rau lawv. Cov no tej zaum yuav paug nto thiab nqhuab, zanitrachivanie khoom. Tsis tas li ntawd urea nitrate chiv thiab muaj teeb meem loj losses ntawm nitrogen (30%), uas ua los ntawm leaching thiab denitrification. Ib tug ammonium sulfate loses tsis ntau tshaj li 3% ntawm cov roj teeb. Nws yuav tsum tau muab sau tseg hais tias muaj yog nitrogen nyob rau hauv lub feem ntau mus siv cuag daim ntawv rau cov nroj tsuag, thiab nyob rau hauv lub tsim ntawm cov qoob loo nws yuav tag nrho loj hlob rau lub caij.

Ntau ammonium sulfate siv rau pov straw. Nyob rau tib lub sij hawm nws dhau mus ua ib tug fertilizer. Hais tias yog, nws yog ua nyob rau hauv hauv av nrog rau straw nyob rau hauv 10 kilograms ib tuj ntawm straw. Yog li nws muaj txhawb mus rau lub ceev degradation ntawm cellulose. Nyob rau hauv no hais txog, nyob rau tib lub sij hawm peb solved ib tug ob peb teeb meem - av tau txais ntxiv chiv, straw thiab siv los tiv thaiv cov ib puag ncig. Yog hais tias lub grain tawm los ntawm 20-30 quintals ib hectare, lub ammonium sulphate ua ke nrog lub straw seem tom qab lawv muaj peev xwm rov qab mus rau cov av rau 40 kg ntawm nitrogen, poov tshuaj 18-24 kilograms, 80 kilograms ntawm phosphorus thiab 35-45 kg leej faj, uas zoo heev pab txoj kev feem pua ntawm cov protein cov ntsiab lus nyob rau hauv cov khoom.
