Parizvino, zvakaoma kufungidzira kukura kwemajindu, munda nemaruva zvirimwa pasina fertilizer. Carbamide (urea) - chimiro chegusiki chine nitrogen mukugadzirwa kwayo, granue yemuchena, grey kana zvishoma. Munguva pfupi yapfuura, fertilizer inogona kutengwa nenzira yemahwendefa, zvichienderana nekuputika kwenguva refu, iyo inopinda muvhu, inopera zvishoma nezvishoma, iyo inopedza nitrate yakawandisa yezvirimwa uye ivhu. Urea ndiyo inonyanya kuiswa ye nitrogen fertilizer, iyo yakavhenganiswa nevhu, inoshandurwa pasi pesimba revhu zvidhori mumamonium carbonate.
Mukukura kwakakura uye kubudirira kwezvirimwa, nitrogen inokosha zvakakosha, sezvo inowirirana zvakananga nekuvakwa kwemamoreksi uye ine chikamu chepuroteni yemiriwo. Kukurudzirwa kunosimudzirwa nekukura kwemichero yezvirimwa kunoita kuti zvidikanwe kufudza carbamide kuwana zvibereko zvakakwirira pane nzvimbo duku dzenyika.
Nzira yekushandisa urea
Mumhepo, ammonium carbonate inokanganisa nokukurumidza, saka kushandiswa kweurea zvakanyanya hakubatsiri. Vashandi vezvekurima vane ruzivo, vachipindura kumubvunzo wekuti ungashandisa sei urea, kupa mhinduro isinganzwisisiki: fertilizer inofanira kushandiswa mumamiriro ezvinhu evhu rakachengetedzwa. Nitrogen pazvishandiso inofanira kuiswa pakarepo muvhu kuitira kudzivirira kurasikirwa kwegaseous ammonia.
Nzira dzekuiswa kweurea
Zvakakosha kuti vakuri vadzidzisi vazive kushandiswa kwecarbamide mubindu. Fertilizer inowanikwa yose, inogona kushandiswa pakupfekedzwa kwepamusoro kwezvirimwa zvose zvine nguva yakareba yekukura. Usati wasima mbeu yemiriwo uye berry, granules inowanikwa zvakananga muvhu: 5 - 12 g yemumanyorera pa 1 mami. Pamusoro pekupfekedza kwepamusoro kwekusimudza mbeu 20 - 30 g ye carbamide inoderedzwa mu 10 malita emvura. Pasi pemuti unotakura carbamide, korona inowanikwa muvhu pamwe chete nezvose zvinoratidzika. Inenge 200 g yeUrea inoshandiswa pasi pemapuroti, uye 120 gramu ye cherry uye plum.
Zvinokosha: carbamide acidifies ivhu, saka, kuitira kuti asidire asidi, chimestone inokurudzirwa: 800 g yemarestone yevhu pa 1000 g ye urea.
Foliar kupfeka ne carbamide
Pazviratidzo zve nitrogen nenzara yemiti, uyewo kana pakadonha michero uye majiroji, itai kupfeka kwepamusoro kwemafiroar nekusvibisa ne carbamide kubva mumunda weperi sprayers. Pamberi peammonium nitrate, iyo inoshandiswa nokuda kwezvinangwa zvakafanana, urea inobatsira zvikuru-inopisa mashizha mashoma. Kunze-midzi yekuzadza necarbamide munguva yekukura inowanikwa pamwero we 3 malita egadziriro yekushanda pa100 m². Mhinduro yekushanda yemiriwo yakagadzirwa nenzira inotevera: 50 - 60 g ye carbamide per 10-liter bucket yemvura. Nokuda kwezvirimwa nezvirimwa, mushonga wekushanda unogadzirirwa pamyero we20-30 g pamubhati wemvura.
Urea senzira yekuchengetedza mbeu
Carbamide inoshandiswa senzira inoshanda yekudzivirira zvirwere. Pakutanga kwemazuva ekudziya kwemazuva asati atanga kubwinya
Kuti dzivirire zvirimwa kubva pachiganda, ruvara rwepepuru nedzimwe zvirwere zvinotapukira, kuputira kunoitwa munguva yekutanga nguva yekuwa mashizha, muvhuvhu. Chibereko chemiti inobereka michero uye berry mabhanhire inoshandiswa, uyewo mashizha akawa. Mhinduro yacho yakagadzirirwa yakafanana neyokuparadzwa kwezvipembenene zvinokuvadza.
Kushandiswa kwakakodzera kweurea kunokubvumira kuwana zvizhinji zvakakohwa!
