Methylene Urea (MU) imapangidwa kuchokera ku urea ndi formaldehyde nthawi zina. Ngati urea imagwiritsidwa ntchito kwambiri mukamachita urea ndi formaldehyde, urea wachidule wa urea formaldehyde amapangidwa pang'onopang'ono.

Kutengera kusungunuka kosiyanasiyana kwa feteleza wa nayitrogeni m'madzi, nayitrogeni amatha kugawidwa mu nayitrogeni wosungunuka m'madzi (WN), madzi osungunuka asafe (WIN), nayitrogeni wamadzi otentha osungunuka (HWN), ndi madzi otentha osasungunuka asafe (HWIN). Madzi amatanthauza 25 ± 2 ℃ madzi, ndipo madzi otentha amatanthauza 100 ± 2 ℃ madzi. Digiri yotulutsa pang'onopang'ono imawonetsedwa ndi index index (AI). AI = (WIN-HWIN) / WIN * 100%. Mitundu yosiyanasiyana ya AI imasankha kutulutsa pang'onopang'ono kwa methylene urea nitrogen. Maunyolo amfupi amatha kusungunuka komanso kuthetsedwa mosavuta ndi tizilombo tating'onoting'ono m'nthaka, chifukwa chake maunyolo otalikirapo samasungunuka ndipo amafunikira nthawi yochulukirapo kuti athetsedwe ndi zamoyo zazing'ono.

Njira yathu yopangira MU imagwiritsa ntchito ukadaulo wathu wopangidwa ndi setifiketi, womwe umakhala ndi njira yosavuta yodziwira mosavuta. Titha kupanga granular ndi ufa MU, yomwe imakhala ndi madzi ozizira osasungunuka asafe kuchokera 20% mpaka 27.5%, index index kuyambira 40% mpaka 65% ndi nitrogen yonse kuyambira 38% mpaka 40%.

 Njira yogwiritsira ntchito imagwiritsa ntchito kutentha kwa urea ndikutulutsa kutentha kokwanira, komwe kumawononga mphamvu zochepa. Granular yopangidwa imakhala yolimba komanso fumbi laling'ono.

MU mu mawonekedwe amtunduwu amakhala ndi kukula kuyambira 1.0mm mpaka 3.0mm, ndipo ufa umakhala pakati pa 20 mesh mpaka 150 mesh.

MU ndiyofunikira kutulutsa pang'onopang'ono nayitrogeni. Mavitamini a MU amatulutsa ndikusungunuka pang'onopang'ono pansi pa madzi ndi zamoyo zazing'ono m'nthaka. MU yoyeretsedwa ndi yoyera ndipo imatha kupangidwa kukhala ufa kapena granular. Ambiri amagwiritsidwa ntchito kuphatikiza kapena kusakaniza feteleza wa N, NP, NK kapena NPK. Kuchita bwino kwakukulu kumafikira pamene MU iphatikizidwa ndi magwero ena osungunuka a nayitrogeni. Mwa kusakaniza kuchuluka kapena kuchuluka kwa MU, kuwunika kosiyanasiyana kwa NPK ndi magawo a Slow Release Nitrogen atha kufikiridwa.

UBWINO

Nitrogen mu MU imatha kutulutsa pang'onopang'ono, yomwe imapewa kuwotcha mizu kapena masamba, kukula kwakukulu kwa mbewu, ndikuthawa feteleza. MU ili ndi nitrogen yokhazikika komanso yotetezeka, yomwe imakwaniritsa ntchito zambiri, kuphatikiza kulima, kulima maekala akulu, zipatso, maluwa, turf ndi mbewu zina. Chifukwa chake, MU yathu imagwiritsidwa ntchito kwambiri komanso yodalirika.
