Yintoni urea njengesichumisi. Urea (isichumiso): Imiyalelo

begadi abaninzi, uthandwa abalimi namhlanje thetheki indlela kunokwenzeka ukwenza ngaphandle yesichumiso. Ngenxa yokuvundisa ehlangeneyo, mziba ukukhula kwesityalo ukukhula ngokukhawuleza, kusekwe elihle, namahlamvu oluchumileyo, inkqubo ingcambu, ngaphantsi boniswa sifo. Kulo mzekelo, i Into esemqoka - ungayibaxi kwaye bazi oko umntu ofanelekileyo isichumiso ke ukuba kuba mnandi izimanga.

Yintoni urea?

Urea njengesichumisi lisetyenziswa jikelele ukuba ukukhula, uvelise isivuno, ulondolozo lwezityalo zikwimeko nobuqaqambileyo. Nitrogen kubalulekile nje imifuno kunye nezityalo zokuhomba. Kuyinto khona kwiproteni kwaye ikhuthaza ukukhula ngokukhawuleza. Ngenxa yokungabikho izityalo nitrogen kangako nezihluma, amagqabi kunye amagqabi ejiyileyo, encinanana, umbala oluhlaza okanye elityheli ukukhanya. yayisel 'ityatyambile na awe, isiqhamo ayikho zibambene nayo.

Yintoni urea? Njengesichumisi asetyenziselwa ukusetyenziswa zabucala. Urea kuqwalasele kakhulu, kumafa yayo iqulathe malunga nama-45% nitrogen. Oko kubizwa ngokuba isichumiso jikelele, ezilungele zonke iintlobo zezityalo. Imbonakalo oko amaso ngaphaya okanye ezimhlophe granular, ngokugqibeleleyo enyibilikayo emanzini kwaye kungekho ivumba. Y urea kunokwandisa hygroscopicity kwi ukufuma ephakamileyo. Isetyenziswa njengento yokugquma phezulu izityalo e cala kwimihlaba urea (isichumiso).

Imiyalelo Sebenzisa

Urea ingasetyenziswa kuzo zonke iintlobo zemihlaba, nkqu namanzi-ungene, kuba ngokugqibeleleyo esisigxina emhlabeni kwaye neetyuwa ezifana kokuhlanjwa ammonium nitrate. Urea kusetyenziswa zombini ukuze avale phezulu, kunye nesichumiso esisiseko. Kuba izityalo yemifuno urea kufuneka zenziwe phambi kokutyala kunye loke ngexesha lonyaka ezikhula ne nedosi ye-5-10 g nganye-1 m ^2. Ngaphambi kweentyatyambo kuyimfuneko ekwakuthululwa isisombululo-50 g 10 litre yamanzi, oko flow engumzekelo - 3 L / 100 m ^2. Kuba amatyholo zokuhombisa kunye neziqhamo kunye nemithi kunokuba urea lusidla ngqo emva kweentyatyambo kwaye kwakhona malunga nesisombululo ngenyanga ka-30 g / 10 l yamanzi.

urea nomthamo

Wonke isichumiso uneempawu zawo ukuba kufuneka ingqalelo phambi kokuba uyisebenzise injongo eyenzelwe yona. Ammonium carbonate emoyeni ngokukhawuleza kakhulu ubola, kulandela - ubuso isicelo urea yi nokungaphumeleli kwawo. Oku wayichitha imali, kuba isityalo akazamkeli izinto eziyimfuneko kuye. iindlela zokulima bacebisa ukusetyenziswa urea kwibala ezikhuselweyo. Emva kokukhulelwa kufuneka ngoko nangoko ibephakathi emhlabeni, ekuphela kwendlela ukuthintela ukuphulukana ammonia sukube. Kufuneka wazi ukuba yintoni na urea nje isichumiso ngokukhawuleza ndakuhlambulula neetyuwa, ngoko ke eyona ndlela iphumelelayo yokwenza phantsi ingcambu sesityalo ngohlobo kwesisombululo.

Ukhuselo imithana kunye nemithi

Urea isetyenziswa kuphela njengento yokugquma phezulu, kodwa njengendlela izinambuzane. Xa kufika imihla yasentwasahlobo efudumeleyo, kanye umxube urea kufuneka zisetyenziswe ukulwa nezinambuzane ubusika ezifana weevils lokudubula kwawo, iintwala, psylla, kunye nabanye. Le nkqubo kufuneka yenziwe phambi kokuba ithupha ukudumba. Lungiselela indlela ngokuba ulawulo lwezinambuzane Ilula gqitha, kuba kufuneka exutywe ne 10 litre yamanzi 0.5 iilitha isisombululo oludibeneyo ichiza.

Urea ukwakhusela izityalo ibala nemfusa kukujaduka, ukutshiza ngoxa kubanjelwa ekwindla, xa amagqabi nje ekuqaleni ukuze bawe. Konke kufuneka ukuqhubekekisa amagqabi - kufana iwile, nalowo akwasala kwamatyholo nemithi. Isisombululo ilungisiwe ngendlela efanayo ulawulo lwezinambuzane.

ukutyebisa houseplants

Ngokupheleleyo zonke izityalo kufuneka yokuvundisa, kodwa kufuneka ucinge kabini phambi kokuba usebenzise isongezelelo njengoko urea (isichumiso) ukwenzela izilwanyana eziluhlaza zasekhaya. Isicelo ngenayo izityalo nitrogen kuyimfuneko kuba likuvumela ukuba wenze isithsaba esihle, ukukhawulezisa ukukhula, ukuthintela ukuwa yellowing namagqabi. Urea kuqwalasele kakhulu, ngoko nokusetyenziswa kwayo kufuneka aphathwe ngokuqaphela okukhulu. Ukuba ebala idosi, oko kungenzeka ukuba silahlekelwe isilwanyana sakho, okanye onakalise imbonakalo yakhe.

Kufuneka iqondwe into le urea. Njengoko sichumisi efanelekileyo ekudaleni nohlaza, yamahlamvu nohlaza. Kwaye ngenxa kweentyatyambo izityalo, nitrogen ayikho nje kuluncedo, ekubeni ukucola phantsi surplus amathupha inkqubo Ukwakheka. Iibhalbhu (hyacinths, Hippeastrum), umthi (orenji, nemikhiwane, lemons), kanti kuyo kumila (irises, calla iinyibiba) ukususela kwimihla yokuqala yobomi oswele nitrogen top-yokuxhela, ngoko zingakotshwa ivundiswe urea ngaphandle naluphi na uloyiko. Kodwa ezinabileyo (Caladium, Gloriosa) kufuneka zidluliselwe emva imbonakalo amagqabi yokuqala. Urea nje isichumiso for houseplants esetyenziswa isisombululo. Kuthetha ukulungiselela izinga 20 g 10 litre yamanzi, oko kwanele-10 m ^2.

Lwebele imifuno kunye neziqhamo izityalo

Urea sichumisi efanelekileyo phantse zonke iintlobo zezityalo, kuyaphumelela ingakumbi kwixesha lokukhula kwezityalo. Qaphela, noba kunjani, ukuba izityalo ezahlukeneyo kufuneka babekwe ukubal ezahlukeneyo, ezifana urea isichumiso. Ukusetyenziswa ikonofile, itswele, ikhaphetshu, iitapile, iipepile kunye neetamati kunokwenzeka kwi iqela malunga 20 g urea m ^{2 nganye.} Ngaphantsi ertyisi kunye cucumber waqalisa isichumiso nganye 7 g / m ^2.

Neetamati, amaqunube, ikhaphetshu kunye cucumber nga athile ukondla isisombululo 25 g / l, wayicola kwi urea xi kabini phambi kokuba uqhawulo amathupha ekwakuthululwa gooseberries, currants kunye nezinye amatyholo iziqhamo kunye berry. Urea negalelo nesithsaba sokuhomba, ngoko ke kucetyiswa ukuba wenze phantsi kwemithi apile (230-250 g), nabantwana namaqunube (110-150 g). Urea uyakwazi ndibachithachithe kwi wequla, uze ugalele kakuhle ngamanzi. It kuvunyelwe ukutyebisa nesisombululo, kodwa ukuze zingabandakanywa yokunkcenkceshela engenakwenzeka.

Ukuba Thelekisa kunye nezinye urea initrogen izichumisi, ezifana ammonium nitrate, ikakhulukazi inzuzo: ubuninzi kukukhawulezisa ukukhula, alungelwe kwamagqabi akungeze isicelo kwaye eqhelekileyo boxinzelelo angazange azitshise amagqabi. ukusetyenziswa Efanelekileyo urea leyo iphucula nje kuphela inkangeleko yezityalo, kodwa ukwanceda ukuqinisekisa isivuno sisityebi.
