UREA N46%

Urea, raws li cov khoom ceev ceev- ua cov chiv nitrogen nrog cov ntsiab lus nitrogen siab tshaj plaws tam sim no, yog qhov tseem ceeb "grain catalyst" hauv kev ua liaj ua teb niaj hnub no. Urea N46 yog tsim los siv cov txheej txheem ntau lawm thiab xaiv cov khoom zoo - zoo raw khoom. Nws haum rau ntau hom av, qoob loo, thiab qoob loo nyiaj ntsuab. Nws sai sai muab cov ntsiab lus nitrogen uas xav tau rau kev loj hlob ntawm cov qoob loo, tshem tawm cov nplooj daj thiab cov yub tsis muaj zog, thiab pab koj kom tau txais cov qoob loo golden.

UREA N46 Cov ntsiab lus:

Tag nrho Nitrogen (N):Ntau dua lossis sib npaug li 46%

Biuret Cov ntsiab lus:Tsawg dua los yog sib npaug li 0.9% (ua tau raws li cov qauv kev nyab xeeb, tsis muaj cov noob hlawv)

Particle Loj:1.18mm - 3.35mm (ib txwm granules, haum rau tshuab seeding)

Moisture:Tsawg dua lossis sib npaug li 0.5% (tseem nyob dawb- ntws thaum lub sijhawm ntev - khaws cia)

*Faj seeb: Cov no yog cov qauv tsis zoo rau cov hwm -qib ua liaj ua teb urea. 46% nitrogen cov ntsiab lus yog qhov tseem ceeb kom zoo dua qhov txawv ntawm urea los ntawm lwm cov chiv nitrogen xws li ammonium bicarbonate.*

Scope thiab siv

Urea N46 muaj ntau yam kev siv thiab ua haujlwm ua "ntsuab cav" rau kev loj hlob ntawm cov nroj tsuag:

1. General Base Fertilizer:Haum rau cov qoob loo xws li nplej, pob kws, nplej, paj rwb, thiab txiv laum huab xeeb. Tshaj tawm ua ntej plowing kom tseg lub zog rau tag nrho lub sijhawm loj hlob.

2.Topdressing rau Seedling Vigor:Rau zaub (piv txwv li, cabbage, spinach), txiv hmab txiv ntoo ntoo (piv txwv li, txiv apples, citrus, txiv hmab txiv ntoo), thiab tshuaj yej nroj tsuag. Siv nyob rau theem tseem ceeb ntawm kev loj hlob, nws txhawb nqa qia thiab nplooj loj hlob sai, sib sib zog nqus nplooj ntsuab xim, thiab txhim kho photosynthesis.

3. Foliar Fertilizer (Foliar Spray):Lub siab purity thiab qis biuret cov ntsiab lus ua rau nws haum rau dilution thiab foliar daim ntawv thov, sai sai tshem tawm cov tsos mob ntawm nitrogen deficiency nyob rau hauv cov qoob loo.

4.Industrial thiab Compound Fertilizer Raw Khoom:Kuj tseem ua cov khoom siv tseem ceeb rau kev tsim cov tshuaj chiv ntauwd, urea -formaldehyde resins, thiab ntau dua.

Txoj kev thov

"Qhov tob tob nrog cov av npog" yog tus yuam sij rau kev txhim kho kev siv hluav taws xob!

1.Deep Placement & Av Npog:Furrow los yog qhov kev thov yog pom zoo, ntawm ib tug tob ntawm 7-10 cm, ua raws li los ntawm tam sim ntawd av npog. Qhov no txo ​​cov ammonia volatilization thiab tuaj yeem ua rau kev siv tau ntau dua 30% piv rau kev tshaj tawm saum npoo av.

2. Tsis txhob sib cuag Seed-Fertilizer:Thaum siv los ua cov noob chiv, khaws qhov sib cais ntawm 5-10 cm los ntawm cov noob kom tiv thaiv biuret los ntawm kev puas tsuaj rau cov noob.

3.Controlled Dosage:Rau cov qoob loo dav dav, siv 10-15 kg ib mu (≈ 150-225 kg / ha) txhua zaus. Rau cov ntoo txiv hmab txiv ntoo, siv 0.5-2 kg ib tsob ntoo nyob ntawm tsob ntoo hnub nyoog.

4. Foliar Spray Ratio:Pom zoo concentration rau foliar spray yog 0.5% -1% (piv txwv li, 50-100 g ntawm urea ib 10 liv dej).

Cia thiab thauj

Txhawm rau tswj cov khoom zoo tshaj plaws, thov ua raws li cov lus qhia hauv qab no:

1.Moisture thiab Water Protection:Urea yog hygroscopic heev thiab nquag mus rau caking. Khaws rau hauv qhov chaw txias, qhuav, zoo-ventilated warehouse. Tsis txhob muab tso rau sab nraum zoov lossis kev sib cuag nrog av noo (nws raug nquahu kom khaws cov khoom kom siab 10-15 cm saum toj no hauv pem teb).

2. Kev tiv thaiv tshav kub thiab hnub ci:Khaws kom deb ntawm qhov chaw sov. Nyob rau hauv qhov kub thiab txias, urea yog nquag mus rau condensation cov tshuaj tiv thaiv uas tsim biuret, txo cov chiv efficiency.

3. Hluav taws kub thiab tawg kev nyab xeeb:Txawm hais tias tsis muaj kev pheej hmoo combustion, tsis txhob khaws cia ua ke nrog cov tshuaj alkaline xws li txiv qaub lossis cov ntoo tshauv, lossis nrog lwm cov tshuaj, kom tsis txhob muaj tshuaj lom neeg ua rau tsis muaj nitrogen.

4. Lub neej txee:Raws li cov txheej txheem khaws cia, cov khoom no tuaj yeem khaws cia rau lub sijhawm ntev (nws raug nquahu kom siv nws hauv ob xyoos kom tau txais txiaj ntsig zoo).
