Urea yog cov organic chiv ruaj khov uas tuaj yeem txhim kho cov av zoo, muab nitrogen rau cov nroj tsuag, thiab nce qoob loo. Feem ntau, urea chiv yog nyob rau hauv daim ntawv qhuav granules. Urea chiv muaj cov txiaj ntsig zoo, txawm hais tias tseem muaj qhov tsis zoo. Los ntawm kev paub yuav ua li cas siv urea chiv rau koj cov av thiab nws ua li cas nrog lwm cov chiv, koj tuaj yeem zam qhov tsis zoo no thiab tau txais txiaj ntsig ntau li ntau tau.

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, nrog qhov kub ntawm 0 - 15 ° C, nrog cua me me lossis tsis muaj cua. Ntawm qhov txias dua qhov ntawd, cov av yuav khov, ua rau nws nyuaj rau urea nqus mus rau hauv av. Thaum siab dua thiab cua daj cua dub, urea yuav decompose sai dua ua ntej nws muaj sijhawm los nqus mus rau hauv av.

Kauj Ruam 2. Thov urea chiv nrog urease inhibitor ua ntej cog

Urease yog ib qho enzyme uas ua rau muaj tshuaj lom tshuaj uas yuav hloov urea rau hauv nitrate uas cov nroj tsuag xav tau. Ua ntawv thov urea ua ntej cog yuav ua rau kom cov urea poob ntau ua ntej nws tuaj yeem nqus tau los ntawm cov nroj tsuag. Siv cov chiv nrog urease inhibitors tuaj yeem ua rau qeeb cov tshuaj lom neeg thiab pab khaws cov urea hauv cov av.

Kauj Ruam 3. Tshaj tawm cov tshuaj urea sib npaug thoob plaws hauv av

Urea tau ntim thiab muag nyob rau hauv daim ntawv ntawm cov pellets lossis cov khoom me me, ua cov granules. Tshaj tawm cov tshuaj urea nrog cov tshuaj chiv nthuav tawm lossis nphoo cov pellets los ntawm txhais tes tusyees thoob plaws hauv av. Hauv feem ntau cov nroj tsuag, nchuav cov urea kom ze rau cov hauv paus hniav lossis thaj chaw uas koj yuav cog cov noob.

Kauj Ruam 4. Dej cov av

Ua ntej tig mus rau nitrate xav tau los ntawm cov nroj tsuag, urea yuav xub dhau los ua ammonia roj. Txij li cov roj tuaj yeem nqus tau yooj yim los ntawm cov av saum npoo av, ua chiv nyob rau hauv cov av ntub yuav pab tau urea nqus mus rau hauv av ua ntej pib tshuaj lom neeg pib. Txoj kev ntawd, ntau cov tshuaj ammonia raug kaw nyob ntawd.

Kwv yees li 1 cm ntawm cov av saum toj yuav tsum tau ntub kom khaws cov roj ammonia ntau li ntau tau hauv cov av. Koj tuaj yeem ywg dej cov av lossis nthuav urea ua ntej los nag

Kauj Ruam 5. Khawb cov av kom tov cov urea

Kev khawb av los yog lub vaj yog ib txoj hauv kev zoo rau urea chiv kom nkag mus rau hauv av ua ntej cov pa ammonia muaj sijhawm los txau. Siv lub tsheb laij teb, rab diav rawg, lossis lub lauj kaub txhawm rau txhawm rau txhawm rau txhawm rau tso cov tshuaj urea los rau hauv txheej txheej saum toj kawg nkaus.

Kauj Ruam 6. Tswj cov nitrogen uas koj muab rau cov qos ntoo

Qee hom qos yaj ywm tuaj yeem nqus tau ntau ntawm nitrogen, thaum lwm tus tsis ua. Tsuas yog nyob nyab xeeb thiab kho tag nrho cov qos ib yam nkaus. Rau cov qos ntoo, tsis txhob siv cov nitrogen ntau los ntawm urea chiv.

  • Urea chiv tuaj yeem siv ncaj qha rau cov nroj tsuag qos lossis daws nrog lwm cov chiv, tsuav yog cov tshuaj muaj tsuas yog 30% nitrogen lossis tsawg dua.
  • Urea chiv daws uas muaj ntau dua 30% nitrogen yuav tsum tsuas yog siv rau thaj teb ua ntej cog qoob loo.

Kauj Ruam 7. Ua qoob loo qoob loo nrog urea nyob rau hnub ntxoov ntxoo

Urea tuaj yeem siv ncaj qha rau feem ntau ntawm cov nplej, tab sis tsis yog nyob rau hnub uas kub tshaj 15 ° C. Yog tias muab thaum qhov kub tau sov dua, cov nroj tsuag yuav tawm tsw ntxhiab ntawm ammonia.

Kauj Ruam 8. Thov urea ncaj qha rau cov cog pob kws

Cov pob kws pob kws yuav tsum tsuas yog muab urea ncaj qha los ntawm kev kis nws mus rau hauv av kom deb li deb li 5 cm ntawm cov noob. Kev kis ncaj qha mus rau urea yuav ua rau lom cov noob thiab yuav txo qis qoob loo ntau.

Txoj Kev 2 ntawm 2: Sib tov Urea nrog Lwm Cov Chiv

Kauj Ruam 1. Txiav txim siab qhov zoo tshaj plaws cov chiv sib piv

Cov chiv sib piv-tseem hu ua N-P-K tus lej-yog cov lej ntawm peb tus lej uas qhia tias muaj pes tsawg ntawm cov chiv sib xyaw los ntawm qhov hnyav. Qhov sib xyaw no yog tsim los ntawm cov chiv uas muaj nitrogen, phosphorus thiab potassium. Yog tias koj tau tshawb fawb ib qho piv txwv ntawm koj cov av hauv vaj, koj yuav tuaj yeem txheeb xyuas qhov piv txwv zoo ntawm cov chiv los pab kho qhov tsis txaus hauv cov av.

Cov neeg feem coob uas nyiam ua teb tuaj yeem yuav cov chiv sib xyaw uas haum rau lawv cov kev xav tau ntawm lub vaj lossis khw muag khoom vaj

Kauj Ruam 2. Sib tov urea nrog cov chiv ntxiv los tsim cov chiv sib xyaw kom ruaj khov

Urea muab cov nroj tsuag nrog nitrogen. Txawm li cas los xij, lwm cov ntsiab lus xws li phosphorus thiab potassium kuj tseem ceeb rau kev noj qab haus huv ntawm cov nroj tsuag. Cov chiv uas koj tuaj yeem sib xyaw thiab khaws tau zoo nrog urea yog:

  • Calcium cyanamide
  • Cov poov tshuaj sulfate
  • Poov tshuaj magnesium sulfate

Kauj Ruam 3. Sib tov urea nrog qee yam chiv kom fertilize cov nroj tsuag tam sim ntawd

Muaj qee cov chiv uas tuaj yeem sib xyaw nrog urea, tab sis yuav poob lawv cov txiaj ntsig tom qab 2-3 hnub vim muaj kev cuam tshuam uas tshwm sim ntawm cov tshuaj hauv cov chiv. Cov chiv uas poob rau pawg no yog:

  • Chilean nitrate hmoov
  • Ammonium sulfate
  • Nitrogen magnesium
  • Diamonnium phosphate hmoov
  • Basic slag
  • Pob zeb phosphate
  • Kev hloov pauv ntawm cov tshuaj potassium

Kauj Ruam 4. Tiv thaiv cov tshuaj uas tsis xav tau los ntawm kev ua qoob loo

Qee cov chiv yuav hnov mob nrog urea los tsim cov tshuaj tiv thaiv tsis ruaj khov lossis tig cov chiv sib xyaw ua ke tsis muaj txiaj ntsig. Tsis txhob sib tov urea nrog cov chiv hauv qab no:

  • Calcium nitrate
  • Calcium ammonium nitrate
  • Ammonium nitrate limestone
  • Ammonium sulfate nitrate
  • Nitropotas
  • Cov tshuaj potassium ammonium nitrate
  • Superphosphate
  • Triple superphosphate

Kauj Ruam 5. Sib tov urea nrog cov chiv nplua nuj hauv phosphorus thiab potassium kom ua kom muaj cov chiv sib npaug

Los ntawm kev ua raws daim ntawv teev npe ntawm cov chiv uas muaj txiaj ntsig zoo thiab tsis txhob sib xyaw nrog urea, xaiv qhov chaw ntawm phosphorus thiab potassium ntxiv rau koj cov chiv sib xyaw. Cov ntaub ntawv no muaj dav nyob hauv khw muag khoom cog lossis vaj.

Ntxiv txhua qhov chiv uas koj xaiv raws li lawv qhov hnyav sib piv. Sib tov kom sib npaug. Koj tuaj yeem ua qhov no hauv lub thoob loj, lub tog raj kheej, lossis nrog cov neeg kho tshuab

Kauj Ruam 6. Tshaj tawm cov chiv raws urea sib npaug thoob plaws tsob ntoo

Thov cov chiv sib tov raws li koj xav nrog urea ntawm nws tus kheej, piv txwv li kis nws tusyees thoob plaws hauv av. Tom qab ntawd, dej thiab hliv cov av kom cov chiv sib xyaw rau hauv.

Urea tsis ntom heev thaum piv rau lwm cov chiv. Yog tias koj tab tom siv lub tshuab tig los nthuav cov urea-raws cov chiv hla thaj tsam loj ntawm kev ua liaj ua teb, khaws qhov nrug qis dua 15 m kom cov chiv kis tau zoo ib yam

Lub tswv yim

  • Ib txwm ua raws cov lus qhia rau kev siv teev nyob rau ntawm daim ntawv lo ntim ntim khoom lag luam.
  • Kab lus no tham txog qhov sib piv ntawm cov chiv. Tsis txhob cuam tshuam qhov piv ntawm cov chiv nrog cov ntsiab lus chiv. Qhov sib piv ntawm cov chiv yuav qhia rau koj - los ntawm qhov hnyav - ntau npaum li cas ntawm cov chiv yuav tsum tau ntxiv rau cov chiv sib xyaw uas koj xav ua. Lub caij no, qib chiv qhia koj ntau npaum li cas ntawm txhua tus neeg hauv cov chiv. Txhawm rau siv "cov ntsiab lus chiv" raws li kev txiav txim siab ntawm "chiv piv", faib txhua tus lej hauv cov ntsiab lus chiv los ntawm qhov tsawg tshaj plaws ntawm peb tus lej.

Ceeb toom

  • Ntau dhau nitrate hauv cov av tuaj yeem hlawv cov nroj tsuag. Ua ntawv thov urea ua kom cov av ntub yuav tiv thaiv kom tsob ntoo tsis txhob hlawv.
  • Ib txwm khaws urea thiab ammonium nitrate cais.
