Urea takin zamani ne wanda yawanci yake buƙatar amfani dashi. Babban aikinta shine barin kowane abu mai cutarwa a cikin ƙasa, kuma aikace-aikace na dogon lokaci bashi da illa mara kyau. A cikin masana'antu, ana amfani da ammoniya na ruwa da carbon dioxide azaman albarkatun kasa don haɗa urea kai tsaye ƙarƙashin yanayin zafin jiki mai ƙarfi da yanayi mai matsi. Baya ga amfani da shi azaman sinadaran hada sinadarai, ana iya amfani da urea a adadi mai yawa don wasu kayayyakin sinadarai, magunguna, abinci, sinadarai masu rini, masu shan danshi, da masu kara karfin viscose, Wakilin karewar Resin, injin dizal injin da ke shayar gas sauran kayan samarwa.

Kariya kan amfani da urea:

1. Urea ya dace da taki mai tushe da kuma ado mai kyau, wani lokacin kuma a matsayin takin zamani. Ya dace da dukkan albarkatu da dukkan ƙasa. Ana iya amfani dashi azaman taki mai tushe da kuma ado mafi kyau. Ana iya amfani dashi a cikin filayen busassun paddy. A cikin ruwan alkaline ko alkaline, sinadarin urea yana da sinadarin hydrolyzed don samar da ammonium nitrogen, kuma yin amfani da farfajiyar zai haifar da nakasar ammoniya, don haka ya kamata a yi amfani da kasar murfin mai zurfin.

2. Bayan an fesa urea a saman filin paddy, ammonia volatilization bayan hydrolysis shine 10% -30%. A cikin ƙasar alkaline, asarar nitrogen ta gurɓataccen ammoniya shine 12% -60%. Arkashin zazzabi mai zafi da zafi mai yawa, ammonia volatilization na urea na iya ƙone shuke-shuke da hanzarta ƙimar nitrification. Sabili da haka, yana da matukar mahimmanci ayi amfani da urea sosai da amfani da ruwa don ɗaukar takin zamani.

3. Saboda urea na iya tara adadi mai yawa na ammonium ions a cikin ƙasa, zai ƙara pH raka'a 2-3. Bugu da kari, urea kanta tana dauke da wani adadin biuret. Lokacin da hankalinsa yakai 500ppm, zai shafi amfanin gona. Tushen da tsiro suna da tasirin hanawa, don haka urea ba abu mai sauƙi ba ne don amfani da shi a matsayin taki iri, takin zamani da takin foliar. Abubuwan cikin urea a cikin wasu lokutan aikace-aikacen bazai zama da yawa ba ko yawa sosai. Bayan an lalata kayan amfanin gona ta hanyar biuret, an kafa shingen kira na chlorophyll, kuma ganyayyakin suna bayyana chlorosis, rawaya har ma da yin faci ko ratsi.

4. Ba za a iya hada Urea da takin gargajiya ba. Bayan an yi amfani da urea, dole ne a canza shi zuwa ammonium nitrogen kafin amfanin gona ya yi amfani da shi. A karkashin yanayin alkaline, yawancin sinadarin nitrogen a cikin ammonium nitrogen zai zama ammoniya kuma zai iya yin amfani da shi. Sabili da haka, urea ba za a iya haɗa shi da toka na tsire-tsire, takin alli magnesium phosphate, Haɗin Carbon ko amfani da takin zamani irinsu ammonium.

Menene tasirin urea akan haɓakar tsiro da yadda ake amfani da shi?

1. Aikin urea shine daidaita adadin furanni. 5-6 makonni bayan fure, fesa 0.5% ruwan ruwa na urea a kan ganye sau 2, wanda zai iya kara yawan sinadarin nitrogen na ganye, hanzarta ci gaban sabon harbi, hana bambancin fure-fure, da kuma yin shekara-shekara Yawan fura ya dace.

2. Fifita manyan kayan gona. Lokacin amfani, amfanin gona tare da yankin shuka mafi girma da ƙimar tattalin arziƙi mafi girma (kamar alkama da masara) ya kamata a fara la'akari dasu. Don amfanin gona na biyu kamar buckwheat, zaku iya amfani da ƙasa da aikace-aikace gwargwadon yanayin tattalin ku. Ko ma kada ku yi amfani da shi, kuma ku ba da cikakken wasa ga tasirin takin zamani wajen haɓaka samarwa. Yi amfani dashi azaman taki na asali ko kayan miya na sama. Urea ya dace don amfani azaman tushen taki da kuma saman miya. Gabaɗaya, ba a amfani dashi azaman taki iri.

3. Aiwatar a gaba. Bayan an yi amfani da urea a cikin kasa, sai a fara sanya shi a cikin ammonium bicarbonate ta hanyar ayyukan kananan halittun gona kafin a samu ciwan asalinsu. Saboda haka, ya kamata a yi amfani da shi a gaba. Aiwatar da urea bayan ruwan sama gwargwadon yuwuwa don samun kyakkyawan aikin shan danshi. Lokacin amfani da kayan kwalliya a cikin busasshiyar ƙasa, yi ƙoƙarin shirya shi bayan ruwan sama domin takin ya iya narkewa da sauri kuma ƙasa ta sha kansa.

4. Idan aka adana urea ba daidai ba, zai iya daukar danshi da kuma agglomerate a sauƙaƙe, wanda hakan zai shafi ingancin urea na asali da kuma kawo wasu asara na tattalin arziki ga manoma. Wannan yana buƙatar manoma su adana urea daidai. Tabbatar kiyaye jakar marufin urea cikakke kafin amfani, riƙe ta da hankali yayin safara, guji ruwan sama, da adana shi a bushe, wuri mai iska mai kyau tare da zafin jiki ƙasa da digiri 20.

5. Idan adadi mai yawa ne, yi amfani da murabba'in katako don huda ƙasan kamar 20 cm, kuma barin sarari fiye da 50 cm tsakanin ɓangaren sama da rufin don sauƙaƙe iska da danshi, kuma barin hanyoyin tsakanin tari. Don sauƙaƙe dubawa da samun iska. Idan ba a yi amfani da urea da aka buɗe a cikin jaka ba, dole ne a kulle buɗe jakar cikin lokaci don sauƙaƙa amfani da ita a shekara mai zuwa.
