Mukuona kwevarimi vazhinji, urea ifetireza yepasi rose.Zvirimwa hazvisi kukura zvakanaka, rasa imwe urea kure;Mashizha ezvirimwa akatsvuka uye imwe urea yakakandwa paari;Kunyange kana zvirimwa zviri fruiting uye fruiting effect haina kunyanya kunaka, kurumidza kuwedzera imwe urea;Kunyange urea inoshandiswa sefoliar fertilizer.
Chii chinonzi urea?Kana basa uye chinangwa che urea zvisina kujeka, zvinogona kutungamirira kune kaviri kuedza uye kunyange kukundikana kuzadzisa zvaunoda.Muzviitiko zvakakomba, zvinogona kukanganisa kukura kwembesa, zvichikonzera kuderedzwa kwegoho kana kutokundikana kwezvirimwa!
Munhu wose anoziva kuti urea initrogen fertilizer ine nitrogen yakawanda.Chinhu chakakosha chinodiwa pakukura kwembesa initrogen fetereza.Saka munhu wese anotenda kuti kana chirimwa chiri kukura chisina kunyatsonaka, chinenge chashaya nitrogen fetiraiza.Chaizvoizvo, izvi hazvisizvo.Kana iwe uchiziva basa uye kushanda kwe nitrogen fertilizer, iwe uchaita kushandisa zvine musoro urea.
1: Zvimiro zve urea
Urea ifetireza yakakosha zvikuru uye imwe yemafetireza enitrogen anoshandiswa nevarimi pazvirimwa.Iyo nitrogen yemukati muurea inosvika 46%, inova ndiyo yepamusoro pakati peese mafetireza akasimba.Urea ifetireza isina kwayakarerekera inokodzera ivhu rakasiyana siyana uyezve chero chirimwa.Zviri nyore kuchengetedza, zviri nyore pakufambisa, uye zvine zvishoma zvinokuvadza ivhu.Parizvino ndiyo inonyanya kushandiswa nitrogen fetiraiza mukugadzirwa kwekurima.
2: Basa uye Kushandiswa kweUrea
(1) Urea inogona kukurudzira kukura kwembesa.Iyo nitrogen element muurea chimwe chezvekudya zvakakosha pakukura nekukura kwembesa.Kana chirimwa chikashaikwa nitrogen feteraiza, chinozoonekwa sezvo ruvara rwechirimwa rwuchireruka uye mashizha ekare pajinga anoshanduka yero;Dzinde dzezvirimwa dzakatetepa uye dzisina simba;Mapazi mashoma kana matillers anotungamirira kukukwegura kwembesa nguva isati yakwana;Kana pane kushayikwa kwe nitrogen fertilizer mumiti yemichero, inogona kutungamirira kune zviduku, zvishoma, zvakakora, uye zvakaoma zvematehwe emichero.
(2) Urea inogona kusimudzira kukura kwenhungirwa munguva yekukura kwembesa.Munguva yekukura kwembesa, kushandisa urea kunogona kusimudzira kukura kwenhungirwa muzvirimwa, kunyanya miti yemichero.Kushandiswa kweurea muzvirimwa kunogona kusimudzira nitrogen yemashizha ezvirimwa, kukurumidza kukura kwenhungirwa itsva, nekudzivisa maruva.
(3) Urea, sefetireza yefoliar, inogona kuwedzera zvirimwa nefetereza ichiuraya tumbuyu.Kunyungudusa urea nedetergent mumvura yakachena nekuapfapfaidza pamashizha ezvirimwa kunogona kukurumidza kuzadza mafetireza nekuuraya zvimwe zvipembenene.Kuuraya kwezvipembenene zvakapfava zvakaita semakabheji zvipembenene, hove, nemadandemutande matsvuku zvinosvika pamusoro pe90%.Sefetireza isina kwayakarerekera, urea inotorwa nyore nyore nemashizha uye ine zvishoma zvinokuvadza zvirimwa.
