Okwangoku, kunzima ukucinga ukutshalwa kwintsimi, igadi kunye neentyatyambo zezityalo ngaphandle kwezichumisi. I-Carbamide (urea) - i-organic compound equkethe i-nitrogen ekubunjweni kwayo, i-granule yemhlophe, igrey okanye iphuzi elincinane. Kungekudala, isichumisi singathengwa ngendlela yamacwecwe, ngenxa yengubo enokusilahla, xa ingena emhlabathini, iyaphula ngokukhawuleza, ekhupha i-nitration ngokweqile kwisityalo kunye nomhlaba. I-Urea yinkxalabo ye-nitrogen fertilizer, xa ixutywe nomhlaba, iguqulwa ngaphantsi kwefuthe lemimandla yamancinci kwi-carbonate ye-ammonium.
Ukukhula okuqhelekileyo kunye nophuhliso lwezityalo, i-nitrogen ibaluleke kakhulu, kuba ihambelana ngqo nokwakhiwa kwama-molecule kwaye iyinxalenye yeprotheni yemifuno. Ukukhuthazwa okukhuthazwa kukukhula kwezityalo zityalo kwenza kubekho ukondla i-carbamide ukufumana isivuno esiphezulu kwiindawo ezincinci zomhlaba.
Indlela yokusebenzisa urea
Emoyeni, i-ammonium carbonate iyancipha ngokukhawuleza, ngoko-ke ukusetyenziswa okungaphezulu kwe-urea akusebenzi. Ochwepheshe bezolimo abanolwazi, ukuphendula kumbuzo wokusebenzisa urea, banike impendulo engabonakaliyo: isichumisi kufuneka sisetyenziswe kwiimeko zomhlaba okhuselekile. I-nitrogeni kwisicelo kufuneka ifakwe ngokukhawuleza emhlabathini ukwenzela ukukhusela ukulahleka kwe-ammonia.
Imimiselo yokwethulwa kwe-urrea
Kubalulekile ukuba abatshali beeventi bazi ukuba i-carbamide yesicelo iyifumana engadini. Umququzeleli unyaka wonke, ungasetyenziselwa ukugqoka okuphezulu kwazo zonke izityalo kunye nexesha elide lokukhula. Ngaphambi kokutyala izityalo zemifuno kunye neeberry, i-granules ifakwe ngqo kumhlaba: 5 - 12 g yesichumisi ngasinye kwi-1 m². Ukugqoka okuphezulu kokuphuhlisa izityalo 20 - 30 g ye-carbamide ihlanjululwa kwi-10 ilitha amanzi. Ngaphantsi kwesihlahla sithwele i-carbamide, izithsaba ziqaliswa emhlabathini kunye nendawo yonke. Phantse i-200 g yerea isetyenziswe phantsi komthi we-apula, kunye ne-120 gram ye-cherry ne-plum.
Kubalulekile: i-carbamide iyancedisa umhlaba, ngoko ke, ukwenzela ukunciphisa i-acid, i-limestone icetyiswa: 800 g yomlambo womhlaba ngomzuzu ka-1000 g werea.
Ukugqoka iPoliar nge carbamide
Kwiimpawu zendlala ye-nitrogen yezityalo, kunye nakwiimeko zokuchitha iziqhamo kunye namajikijolo, zenze iingubo eziphezulu zokugqoka ngokutshiza i-carbamide kwi-sprayers egadiweyo. Ngaphambi kokuba i-ammonium nitrate, esetyenziselwa iinjongo ezifanayo, urea inenzuzo enkulu - iyatshisa amaqabunga amancinane. I-root-root fertilizer nge-carbamide ngeli xesha lokukhula lenziwa ngezinga le-3 ilitha yesisombululo sokusebenza ngasinye kwi-100 m². Isisombululo sokusebenza semifuno silungiselelwa ngale ndlela ilandelayo: 50 - 60 g ye-carbamide nganye kwibhakethi ye-10-litre yamanzi. Ngeziqhamo nezityalo zeberry, isisombululo sokusebenza silungiselelwe kwisantya se-20-30 g nganye kwibhakethi yamanzi.
Urea njengendlela yokukhusela izityalo
I-Carbamide isetyenziswe njengendlela efanelekileyo yokulawula iintlekele. Ekuqaleni kweentsuku zokufudumala zasentwasahlobo phambi kokuqala kokuvuvukala
Ukukhusela izityalo kwi-scab, indawo emfusa kunye nezinye izifo ezithathelwanayo, ukutshiza kuqhutyelwa kwithuba lokuqala lokuwa kwamaphepha, ekwindla. Iziqhamo zemithi evelisa iziqhamo kunye neerberry ezihlahleni ziyacutshungulwa, kunye namaqabunga awele. Isisombululo sikulungele ukufana nokutshatyalaliswa kwezinambuzane ezinobungozi.
Ukusetyenziswa kakuhle kwe-urrea kuya kukuvumela ukuba ufumane isivuno esininzi!
