Urea - ntoni na? Urea isichumiso. Ingakumbi, isicelo yentengo

Omnye yemiqathango ezibalulekileyo nokufumana isivuno esihle namaqunube, iziqhamo kunye nemifuno na isondlo ezongezelelweyo yomhlaba nezityalo. Ukuba phambi kokuba kukhetha idla aziphelelanga imveliso zomgquba, ngoku ngongeniselo begadi beza mihla nezichumiso, iphucula kakhulu iziphumo lokuvuna. Enye yezona zinto agrochemical okufunwa-ilungeleleneyo carbamide (urea). Kungenxa yoko le nto amafama aqalile bazibuze urea, nguwo. ingaba into okufanelekileyo, umzekelo, ukuze anyamekele igadi yemifuno okanye lawn?

Urea-isichumiso: iinzuzo

Inzuzo oku kuthetha lukhulu. Ukukhetha yokwenza ezimbiwa, kubalulekile ukwazi malunga urea, akukho kuphela mpembelelo entle kwizityalo, kodwa ke lula ye efanayo emhlabeni. Le yokuvundisa eziphilayo, ngokungafaniyo urea granular, kunzima ukuba babele ngokufanayo emhlabeni, nto leyo enokukhokelela ekubeni unikezelo ayanelisi. Ukongeza, urea abe umphumela ohlala, ngoko kancinci ukhupha amacandelo izimbiwa of yezityalo zasePilippi.

Ngoko ke yintoni na carbamide

Nika ingcaciso emfutshane: Urea - ntoni na le nto, ziziphi iimpawu zayo imbonakalo. Le isichumiso nitrogen ngohlobo ziikristale ezimhlophe okanye esha ngaphaya kwaye ngokukhawuleza enyibilikayo emanzini eziqhelekileyo kunye ammonia elulwelo, nesulfure dioxide. Linyibilike e 132,7 ° C.

Urea-isichumiso unalo ifomula chemical (NH2) 2Co kunye namuhla afunyenwe kwi Yindibanisela carbon dioxide kunye ammonia. Of ixabiso kakhulu isiqulatho nitrogen eliphezulu kanzulu (46%), kubalulekile ubomi bezityalo. Phakathi kwezinye amagama uqhelekileyo urea - urea kunye asidi diamide.

Ukusetyenziswa carbamide (urea)

Sekunjalo, urea - oko kukuthi: iikhemikhali eziyingozi okanye luncedo, kwaye nokuba zingasetyenziswa isichumiso kuba ingca okanye egadini yakho? Apho osetyenziswa rhoqo?

(NH2) 2Co ngokubanzi ifuna kwi ukulinywa kwezityalo, horticulture, nemfuyo sesondlo ingca, leyo additive kwi njini nentlaka fiberboard lemveliso mveliso, kwizikhululo ngamandla thermal kunye hypnotics njalo njalo. Ngapha koko, urea isetyenziswa amayeza njengenye yeekhomponenti ezikhethiweyo kanye anti amalungiselelo kunye kushishino yokutya - ekuveliseni ukuhlafuna itshungama. Ngamanye amazwi, ukusetyenziswa urea okungummangaliso.

Ukugcinwa izichumisi, amanyathelo okhuseleko

imveliso ezinkulu-isikali urea kunye nezinye izinto nitrogen-equlethe kwimigangatho karhulumente kwi-Russian Federation yi himpredpriyatiya Perm, Togliatti, Cherepovets, Novomoskovsk.

Ukuhlenga ayinayo ikeyiki ngexesha yokugcina, ngaphandle kokuba yenziwe ngohlobo granules, zahlanganiswa kwiingxowa manzi. Hi ndlela leyi, izinto karhulumente granular lula zokufefa uniform kumphezulu womhlaba yasemyezweni, ukuphuculwa kwemveliso yezolimo.

izikhongozeli nokupakishwa ukuze itha iphepha okanye ngaplastiki, kwaye kananjalo urea-isichumiso ugcinwe kakuhle ngeengxowa Polymer eqhelekileyo nokuba phandle. Owona imfuneko iimeko zokugcina - ukhuselo ukunyakama, kwaye xa yokugcina isambuku kwakhona kubalulekile ukuphepha ukunxulumana nabanye kusitsha. Igama eqhelekileyo ukusetyenziswa urea na iinyanga ezintandathu, kodwa iimveliso neevenkile uyakwazi ukugcina umgangatho walo malunga nesi-2 iminyaka.

Ukwenzela ukuqinisekisa ukhuseleko kufuneka zinganxitywa ukhuseleko aphantsi xa usebenzisa nitrogen isichumiso, ezifana iimpahla kunye nezihlangu, irabha okanye c / b iiglavu, baphefumla. Ngokuxhomekeke kwimiqathango enjalo ukuthintela ukutsha ubuthi.

Autumn Garden processing

Garden Treatment kunye urea ekwindla enokwenziwa kunye nesisombululo okanye ngumgubo owomileyo. Enoba kunjalo, kuba sisixhobo enkulu nabantwana periodic zokutshiza, ama-apile, amapere, entlakohlaza ekuqaleni de ithupha iye yakhula. Emva koko, unyango umyezo yenziwa emva iseti iziqhamo, kwaye ukuwa emva kwexesha. isisombululo urea kuya kunceda ukukhusela isivuno elizayo kuzo zonke iintlobo zonke izinambuzane eziyingozi. Kananjalo lokubopha elungileyo.

Garden ekwindla urea processing lwenziwa ngale ndlela ilandelayo. Nitrogen isichumiso (500-700 grams) liyangxengwa ukuya emele yeelitha-10 yamanzi kunye luyacolwa kutshizwa kwi iinkuni umhlaba ngeenxa buti. Kungcono abaphinda oku kweli kokwindla, ngo-Oktobha-Novemba, kubushushu alithe gangqa degrees 10.

Urea for imithi yeziqhamo

Spring ngokulima kuya kunceda lokuyigxotha le ezidla izinambuzane emhlabeni. Ukongeza, ezinye urea kancinane ukuvuka, umzekelo, nabantwana eya kuthintela imithi eneentyatyambo yokuqala ukusuka iqabaka.

Ukukhusela apile, Plum, emibhaka kunye cherry intwala, igqabi, apile atyatyambe qongqothwane kunye nezinye izinambuzane zemithi kutshizwa ekupheleni kweentyatyambo, malunga ngeveki.

Urea abasuka 7-10% isetyenziselwa unyango yasekwindla emva kwexesha, nto leyo yinto ebalulekileyo ekulungiseleleni yomyezo ukulungiselela ixesha elizayo. Isiphumo - an ukuxhathisa ukwanda iqabaka, uphuhliso olufanelekileyo imithi kunye neziqhamo.

Urea ukuba negadi

ukutya okunjani kubalulekile ukuba izityalo elinywa emyezweni, kodwa akwanelanga lokuqokelela ogqwesileyo iziqhamo zabasebenzi basefama.

Urea-sichumisi esisetyenziswa ngokubanzi imifuno njenge additive ngokupheleleyo. Kuba unyango double eliphezulu zucchini kunye nesisombululo ulwelo ngexesha iziqhamo maqanda, apho isithuba olwaneleyo iintsuku 10-12.

Kuba beet indibaniselwano ifanelekileyo urea uya (1 tbsp. Spoon) ne potassium chloride (15 g) kunye boric acid (5g), nto leyo eya kuqinisa inkcubeko kunye nokukhuthaza imigangatho elungileyo uphuhliso leaf. Yandisa isivuno ngobuncinane bama-20% aokusetyenziswa isichumiso umhlaba nezinki sulfate, yemanganizi ngobhedu elingqamene ka 10/10/10 g ilitha-10 emele yamanzi nganye.

Cucumber aba ahlekisayo kakhulu, ngoko ukuze ufumane isiphumo elungileyo kufuna ukuba kwenziwe ngendlela emanyeneyo. Ukutshiza umgangatho urea iza kuphucula nokukhawulezisa kakhulu ngexesha fruiting. cucumber Greenhouse iza kuphuhlisa kakuhle ngokusebenzisa izondlo rhoqo kwamagqabi akungeze sele kwiveki 5, amaxesha ubuncinane 2 ngenyanga nganye. Le umthamo izimbiwa ubume lula ukujonga ngokwabo, ezisekelwe phezu iingcebiso kumqulu. Ukubunjwa kungabandakanya: urea, potassium kwezichumiso, superphosphate kunye nitrate.

Ukulungiselela tomato luncedo sokutshiza urea ulwelo izityalo enedodo kwimiyezo (1 tbsp. Spoon) ngeqondo flow obumalunga 10 litre isisombululo nganye kwamatyholo elinesibini.

Uqwalaselo namatyholo berry

Urea singanyangwa nazo zonke iziqhamo ozithandayo: amaqunube, gooseberries, currants kunye nabanye. Oku kuya kukhuthaza eneentyatyambo intabalala nesivuno esihle kwixesha elilandelayo. Umzekelo, ngo-Agasti amaqunube umgquba kakuhle urea granular (30 g).

Gooseberry kunye currant nokulungisa utywala spray: 1 tbsp. Ngecephe urea 2 grams ye zinc sulfate kunye boric acid. Ukwenza inkqubo xa amaqanda nezidubula, nto leyo ukukhula 10-20% msinyane nokuphuculwa isivuno.

Urea njengesichumisi ukuba iintyatyambo

Abo benza iintyatyambo egadini ethandwayo okanye ufuna bayingqonga indlu yakhe ingca omhle, akukho luncedo ukwazi ukuba rose, carnation, Lilac kunye nengca nengca ethambileyo kwakhona kufuna recharge zonyaka izichumisi nitrogen bezimbiwa emhlabeni.

Kuba ukutya ebalulekileyo ezongezelelweyo wavuka kwisithuba kweentyatyambo intabalala, leyo kwenziwa rhoqo kwiiveki 2 ukusuka ekuqaleni kunye nesisombululo ezibuthathaka urea kunye potassium, iphosphate.

ningazicenti Carnation sele kwiinyanga ezinesiqingatha emva kokutyala ifuna ukutshiza ngeveki urea (50 g) kunye mullein (1:10).

Ukususela kowe-Meyi, xa ekweneni izintso iqala amatyholo Lilac kunokuba amaxesha 3-4 iintsuku 10 zokutshiza lokuphumla nge-1% nesisombululo urea; kwandule ke igadi ziya kubakho ixesha elide ukukholisa kweentyatyambo iluhlaza yaye aqholiweyo umtsalane incasa ekrakra-sweet.

Ukudala echanileyo, oqaqambileyo oluhlaza nengca urea njengesichumisi nengca kutshizwa kwi iziqu kanye amahlamvu inani eliboniswe iphakheji kunye nokwakheka.

Ixabiso urea isichumiso

Nitrogen isichumiso ixabiso urea kuyahlukana nedlela lonyaka kunye nomthamo (Ihowuliseyili okanye neevenkile) - malunga ne-7 ukuya ku-17 amawaka engange ngetoni nganye. Kubaluleke kakhulu buyanceda kuthenga le mveliso in advance, ukuwa kade kwaye ufake kwindawo eyomileyo. Kuphela ngale ndlela ungagcina isixa esikhulu semali ukususela eshotayo spring ngokuqinisekileyo kuya kubangela ukuphuma inani layo.

Urea - nitrogen isichumiso ekhethekileyo, ifanele phantse nawuphi na umhlaba. On yezityalo zasePilippi ukukhula ekuvuseleleni ukusebenza, yokunyakamisa nabo Micro kuyimfuneko, kodwa abangaphangeliyo kunyebeleziso ukhula. Ukuba lula amandla azibizi abangabancedani, kunye nokukhuselwa kwezityalo egadini, urea ukwimo yokuqala phakathi kwezinye iikhompawundi kwizimbiwa.
