Ugbu a, o siri ike iche n'echiche ubi nke ubi, ubi na okooko osisi na-enweghị nri. Carbamide (urea) - ihe oriri nke nwere nitrogen na ngwongwo ya, bu ihe nlekota nke oji, oji ma obu obere odo. N'oge na-adịbeghị anya, a pụrụ ịzụta fatịlaịza n'ụdị mbadamba nkume, n'ihi mkpuchi ahụ dị ogologo, mgbe ọ na-abanye n'ime ala, ọ na-agbaze nwayọ, nke na-ewepụ oke ngosipụta nke ihe ọkụkụ na ala. Urea bụ nri kachasị na nitrogen, mgbe ejikọtara ya na ala, a gbanwere ya n'okpuru nduzi nke microorganisms n'ime ala n'ime ammonium carbonate.
N'ihe na-eto eto nke ọma na mmepe nke osisi, nitrogen dị oke mkpa, ebe ọ bụ na ọ na-emetụta ya na ọkpụkpụ mkpụrụ osisi na ọ bụ akụkụ nke protein protein. Mmetụta a na-akpali site n'uto nke mkpụrụ osisi na-eme ka ọ dị mkpa ịzụ nri carbamide iji nweta mkpụrụ dị elu na obere ala.
Ụzọ eji urea
Na ikuku, carbonate ammonium decomposes ngwa ngwa, ya mere enweghi ike iji urea aba uru. Ndị ọkà mmụta ugbo nwere ahụmahụ, na-aza ajụjụ banyere ụzọ e si eji urea eme ihe, nye azịza na-enweghị mgbagha: a ghaghị iji fatịlaịza mee ihe n'ọnọdụ ọnọdụ nchebe. Nitrogen n'elu ngwa ga-abanye ozugbo na ala iji gbochie ọnwụ nke amonia.
Ụdị maka iwebata urea
Ọ dị mkpa ka ndị na-eto eto novice mara ihe carbamide na-enweta n'ubi ahụ. Fatịlaịza bụ nke zuru ụwa ọnụ, a pụrụ iji ya maka mgbakwasa elu nke ihe ọkụkụ niile na ogologo oge. Tupu ịkụ ihe oriri na beri kụrụ, nsogbu dị n'ime ala: 5 - 12 g nke fatịlaịza kwa 1 m². Maka akwa mgbakwasa nke osisi na-eto eto 20 - 30 g nke carbamide na-diluted na 10 lita mmiri. N'okpuru osisi na-ebu carbamide, a na-amanye okpueze n'ime ala ya niile. A na-eji 200 g nke urea mee ihe n'okpuru osisi apụl, na 120 grams maka udara na piom.
Ihe dị mkpa: carbamide na-eme ka ala dị ala, ya mere, iji mee ka acid ghara ịdị, a na-atụ aro ihe atụ: 800 g nke ala ala maka 1000 g nke urea.
Ngwakọta nke foliar na carbamide
Na ihe ịrịba ama nke nitrogen agụụ na-eri nri, nakwa dịka ịkwanye mkpụrụ osisi na tomato, mepụta akwa mgbakwunye site na ịpịpụta na carbamide site na ndị na-agba ogige pụrụ iche. Tupu ammonium nitrate, nke a na-eji maka otu ebumnuche, urea nwere uru dị oke - ọ na-egbusi obere epupụta.

A na-edozi ihe ngwọta maka akwụkwọ nri dị ka ndị a: 50 - 60 g nke carbamide kwa mmiri ịwụ mmiri 10. Maka mkpụrụ osisi na beri kụrụ, a na-edozi ihe ngwọta na 20-30 g kwa ịwụ mmiri.
Urea dị ka ụzọ isi chebe osisi
