Urea chiv yog qhov ruaj khov, cov organic chiv uas tuaj yeem txhim kho qhov zoo ntawm koj cov av, muab nitrogen rau koj cov nroj tsuag, thiab nce qoob loo ntawm koj cov qoob loo. Feem ntau koj tuaj yeem tau txais nws hauv daim ntawv qhuav, ua kom zoo. Muaj ntau qhov txiaj ntsig los siv urea ua chiv, tab sis urea tsis yog tsis muaj qhov tsis zoo. Paub paub siv urea chiv zoo rau koj cov av thiab yuav ua li cas urea cuam tshuam nrog lwm cov chiv tuaj yeem pab koj zam qhov tsis zoo no thiab tau txais txiaj ntsig ntau ntawm koj cov chiv li sai tau.
Cov kauj ruam
Txoj Kev 1 ntawm 2: Thov Urea ntawm Nws Tus Kheej
Kauj Ruam 1. Ua kom tsawg ammonia poob los ntawm kev siv urea rau hnub txias
Urea yog qhov zoo tshaj plaws nyob rau hnub txias, hauv huab cua ntawm 32 ° txog 60 ° F (0 ° -15.6 ° C), thiab nrog cua me ntsis. Hauv qhov txias dua, av tau khov, ua rau nws nyuaj rau sib xyaw urea rau hauv av. Thaum kub dua, thiab nyob rau qhov cua hlob, cov urea tau tawg sai dua nws tuaj yeem tsau rau hauv av.
Kauj Ruam 2. Siv urea chiv nrog urease inhibitor ua ntej cog
Urease yog cov enzyme uas pib tshuaj lom tshuaj uas hloov urea rau hauv cov nroj tsuag nitrates xav tau. Ua ntawv thov chiv urea ua ntej cog ua rau muaj cov urea poob ntau ua ntej nws tuaj yeem muaj txiaj ntsig rau koj cov nroj tsuag. Siv cov chiv nrog urease inhibitor tuaj yeem ua rau qeeb cov tshuaj tiv thaiv kab mob, thiab pab khaws urea hauv cov av.
Kauj Ruam 3. Muab cov tshuaj urea sib tov hla cov av
Urea tau ntim thiab muag raws li cov khoom me me, khoom noj los yog granules. Tshaj tawm cov tshuaj urea nrog cov tshuaj chiv nthuav tawm lossis nphoo cov pellets los ntawm txhais tes tusyees hla koj cov av. Rau feem ntau cov nroj tsuag, koj yuav xav khaws cov urea ze rau ntawm tsob ntoo cov hauv paus hniav, lossis ze rau qhov chaw koj yuav cog cov noob.
Kauj Ruam 4. Ntub cov av
Ua ntej urea hloov mus rau hauv nitrates koj cov nroj tsuag xav tau, nws ua ntej ua ammonia roj. Vim tias cov pa roj tau yooj yim khiav tawm ntawm cov av, thov siv cov chiv thaum av ntub yuav pab sib xyaw cov urea rau hauv av ua ntej pib tshuaj lom neeg pib. Txoj kev no, ntau ntawm ammonia raug rau hauv av.
Sab saum toj ib nrab ntiv tes (1.3 cm) ntawm cov av yuav tsum ntub kom cov kua ammonia ntau hauv av kom ntau li ntau tau. Koj tuaj yeem ywg dej cov av koj tus kheej, siv urea ua ntej los nag, lossis thov hauv 48 teev tom qab daus los ntawm koj thaj teb tau yaj tag
Kauj Ruam 5. Ua kom cov av sib xyaw urea
Tilling koj cov teb lossis vaj yog ib txoj hauv kev zoo rau suav nrog urea chiv rau hauv av ua ntej ib yam ntawm cov ammonia roj tuaj yeem ploj. Harrow, rub, lossis hoe lub teb chaws txhawm rau sib xyaw urea rau hauv txheej txheej saum toj kawg nkaus ntawm cov av.
Kauj Ruam 6. Tswj cov nitrogen uas koj muab rau cov qos ntoo
Qee hom qos yaj ywm tuaj yeem lis qib nitrogen ntau, thaum lwm tus ua tsis tau. Ceev faj thiab kho txhua tus qos ib yam nkaus. Tsis txhob muab cov qos ntoo cog ntau ntau ntawm nitrogen nrog koj cov chiv urea.
- Urea chiv tuaj yeem siv ncaj qha rau cov cog cog, lossis hauv kev daws nrog lwm cov chiv, tsuav yog cov tshuaj tau ua los ntawm 30% nitrogen lossis tsawg dua.
- Kev daws teeb meem ntawm urea chiv uas ntau dua 30% nitrogen yuav tsum tsuas yog siv rau thaj teb ua ntej cog qoob loo.
Kauj Ruam 7. Fertilize cov nplej nrog urea rau hnub me me
Urea tuaj yeem siv ncaj qha rau feem ntau ntawm cov nplej, tab sis tsis txhob kub tshaj 60 ° F (15.6 ° C). Thaum thov hauv qhov sov sov, cov nroj tsuag yuav muab cov ntxhiab ntawm ammonia.
Kauj Ruam 8. Thov urea rau cov noob pob kws tsis ncaj
Tsuas yog siv urea rau pob kws tsis ncaj, los ntawm kev nthuav cov urea mus rau hauv av tsawg kawg 2 ntiv tes (5 cm) deb ntawm cov pob kws pob kws. Kev kis ncaj qha mus rau urea yog tshuaj lom rau cov noob, thiab txo qis pob kws cog qoob loo.
Txoj Kev 2 ntawm 2: Sib tov Urea nrog Lwm Cov Chiv
Kauj Ruam 1. Txiav txim siab koj cov chiv zoo tshaj plaws
Fertilizer ratios, tseem hu ua N-P-K tus lej, yog cov lej ntawm 3 tus lej uas qhia koj tias muaj pes tsawg ntawm cov chiv sib xyaw, los ntawm qhov hnyav, yog ua los ntawm cov chiv nplua nuj hauv nitrogen, phosphorus, thiab potassium. Yog tias koj muaj ib qho piv txwv ntawm koj cov av kawm, koj yuav tau muab cov chiv zoo sib piv uas yuav pab kho koj cov av cov zaub mov tsis txaus.
Cov neeg nyiam ua teb feem ntau tuaj yeem nrhiav cov chiv ua ntej uas yuav haum rau lawv cov kev xav tau ntawm cov chaw cog ntoo lossis chaw cog vaj
Kauj Ruam 2. Muab cov tshuaj urea nrog rau cov chiv ntxiv los tsim cov chiv sib xyaw kom ruaj khov
Urea muab cov nroj tsuag nrog nitrogen, tab sis lwm cov ntsiab lus, zoo li phosphorus thiab potassium, yog qhov tseem ceeb rau kev noj qab haus huv ntawm tsob ntoo ib yam. Cov chiv uas koj tuaj yeem nyab xeeb sib xyaw thiab khaws nrog urea suav nrog:
- Calcium cyanamide
- Sulphate ntawm potash
- Sulphate ntawm potash magnesium
Kauj Ruam 3. Sib tov urea nrog qee yam chiv ua chiv rau tsob ntoo tam sim ntawd
Muaj qee cov chiv uas tuaj yeem sib xyaw nrog urea, tab sis poob lawv cov txiaj ntsig tom qab 2-3 hnub vim tias muaj kev cuam tshuam uas tshwm sim ntawm cov chiv tshuaj lom neeg. Cov no suav nrog:
- Chilean nitrate hmoov
- Sulfate ntawm ammonia
- Nitrogen magneseia
- Diamonnium phosphate hmoov
- Basic slag
- Pob zeb phosphate
- Kev tua ntawm potash
Kauj Ruam 4. Tiv thaiv cov tshuaj tsis xav tau los ntawm kev ua phem rau koj cov qoob loo
Qee cov chiv yuav cuam tshuam nrog urea los tsim cov tshuaj tsis haum tshuaj, lossis ua kom cov chiv sib xyaw ua ke tsis muaj txiaj ntsig. Tsis txhob sib xyaw urea nrog cov chiv hauv qab no:
- Calcium nitrate
- Calium ammonium nitrate
- Limestone ammonium nitrate
- Ammonium sulphate nitrate
- Nitropotash
- Potash ammonium nitrate
- Superphosphate
- Triple superphosphate
Kauj Ruam 5. Muab cov tshuaj urea nrog rau cov tshuaj phosphorus thiab potassium uas muaj cov chiv zoo
Hais txog cov npe ntawm cov chiv uas yog thiab tsis muaj txiaj ntsig los sib xyaw nrog urea, xaiv cov chaw ntawm phosphorus thiab potassium ntxiv rau koj cov chiv sib xyaw. Ntau yam ntawm no muaj nyob ntawm cov chaw zov me nyuam thiab cov khw muag khoom vaj.
Ntxiv txhua qhov koj tau xaiv cov chiv ua ke, raws li qhov hnyav tau muab los ntawm koj cov chiv piv. Sib tov lawv ua ke kom huv si. Qhov no tuaj yeem ua tiav hauv lub thoob loj, hauv lub log tsheb, lossis nrog cov khoom sib xyaw
Kauj Ruam 6. Tshaj tawm koj cov chiv raws urea sib npaug thoob plaws koj cov qoob loo
Ua ntawv thov koj cov chiv sib tov raws li koj yuav thov urea ntawm nws tus kheej, kis nws tusyees hla cov av. Tom qab ntawd dej thiab ua kom cov av txhawm rau suav nrog cov chiv.
Urea tsawg dua li lwm cov chiv. Yog tias koj tab tom siv cov khoom siv sib kis los nthuav koj cov urea-based chiv hla qhov deb ntawm koj daim teb, ua kom koj qhov dav nthuav dav qis dua 50 ko taw (15.2 m) txhawm rau kis cov chiv sib tov sib npaug
Yees duab - Los ntawm kev siv qhov kev pabcuam no, qee cov ntaub ntawv yuav raug muab qhia rau YouTube
Lub tswv yim
- Ib txwm ua raws cov lus qhia uas muaj cov chiv ua lag luam.
- Kab lus no tham txog kev sib piv cov chiv. Tsis txhob cuam tshuam cov chiv sib piv nrog qib chiv. Cov chiv chiv qhia rau koj, los ntawm qhov hnyav, ntau npaum li cas ntawm cov chiv tshwj xeeb ntxiv rau koj cov chiv sib xyaw. Cov qib chiv qhia koj ntau npaum li cas ntawm txhua tus neeg muaj nyob hauv koj cov chiv. Txhawm rau siv qib chiv los txiav txim siab qhov sib piv ntawm cov chiv, faib txhua tus lej ntawm qib chiv los ntawm qhov tsawg tshaj plaws ntawm 3 tus lej.
Lus ceeb toom
- Ntau dhau nitrate hauv cov av tuaj yeem hlawv cov nroj tsuag. Thov urea chiv rau cov av ntub yuav pab tiv thaiv kom txhob kub hnyiab.
- Ib txwm khaws urea thiab ammonium nitrate cais.
