Nitrogen yog ib qhov chaw ntawm cov khoom noj khoom haus muaj tshwm sim hauv av, tab sis nyob rau hauv cov cheeb tsam txawv climatic cov av muaj ntau. Incredibly me ntsis nitrogen nyob rau hauv lub ntsws ntawm Sandy thiab Sandy loamy xau. Tsis tas li ntawd xwb, tsuas yog 1% ntawm cov khoom no yog muaj rau cov nroj tsuag, yog li nws yog ib qho tseem ceeb heev rau kev siv sij hawm zom cov av nrog nitrogen chiv, thiab dab tsi chiv yuav tham txog hauv tsab xov xwm no.
Qhov tseem ceeb ntawm nitrogen chiv rau nroj tsuag
High-grade nitrogen cov khoom noj khoom haus tsis tsuas yog muaj txiaj ntsim zoo rau cov txiaj ntsig, tab sis kuj ua rau cov khoom qoob loo zoo dua. Vim tias qhov nce ntawm feem pua ntawm cov protein thiab nce lub concentration ntawm ntau cov proteins, cultivated nroj tsuag pib loj hlob sai, lawv cov nplooj yog ntxwv los ntawm tsaus nti ntsuab xim, thiab cov txiv hmab txiv ntoo yog loj loj. Yog hais tias nitrogen tsis txaus, ces nyob rau hauv lub saum toj no-av ib feem muaj me ntsis chlorophyll thiab nplooj tawm me me, poob xim, thiab yield yields. Txo ntawm cov tsis muaj protein ntau thiab cov noob. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tsim tau ua ntej rau kev loj hlob ntawm cov qoob loo, muab cov av nrog tsim nyog npaum nitrogen.
Organic nitrogen chiv
Lawv muaj xws li:
- Tag nrho cov hom ntawm manure, noog droppings, tshwj xeeb tshaj yog duck, nqaij qaib thiab pigeon.
- Cov nplooj lwg. Ib qho me me ntawm nitrogen muaj nyob rau hauv pawg thiab tawm hauv tsev khib nyiab.
- Ntsuab loj. Nws tseem yog tam sim no nyob rau hauv nplooj, xuab zeb silt, lupine, Sweet clover, vetch, clover, lwm yam zoo li
Nitrogen pob zeb hauv av chiv
Cov neeg uas nug tias cov npe ntawm cov npe nitrogen chiv, nws puas tsim nyog tau them sai sai rau daim ntawv:
- Ammonium chiv yog ammonium sulfate, ammonium chloride.
- Nitrate chiv yog calcium thiab sodium nitrate.
- Amide chiv yog urea .
Qhov no yog dab tsi siv rau nitrogen chiv. Ntawm kev muag khoom koj tuaj yeem pom thiab fertilizing, muaj nitrogen ib txhij nyob hauv nitrate thiab ammonia daim ntawv. Tsis tas li ntawd, nws yog ib qhov tsim nyog los paub hais tias nitrogen chiv yog siv nyob rau hauv ua ke nrog phosphorus thiab poov tshuaj chiv. Tej yam yuav tsum tau muaj yog los ntawm superphosphate, pob txha los yog dolomite hmoov, ammonium nitrate. Lub tom kawg yog siv rau cov chaw tsis muaj zog txaus humidified nrog cov siab concentration ntawm av daws. Nws yog feem ntau tov nrog superphosphate thiab ib tug neeg sawv cev neutralising. Qhov no yuav siv rau hauv cov paj hom qoob loo, vim hais tias cov kawm ntawv thiab txoj kev assimilation ntawm nitrogen nyob rau hauv lawv yog txawv.
On ib qho kev ntsuas, kua nitrogen chiv siv, uas yog sib npaug faib, zoo nqus thiab ua haujlwm rau lub sijhawm ntev zog. Txawm li cas los xij, ib daim ntawv qhia txog nitrogen los ntawm cov nroj tsuag tuaj yeem ua kom tsuas yog siv nrog ib qho ntawm cov organic thiab pob zeb hauv av chiv.
