Munguva pfupi yapfuura, kukohwa munharaunda yeguta remuguta hakufari here? Saka, inguva yekudzidza kuti furezi inonzi urea yakagara ishandiswa kwete mumunda chete, asiwo mumunda. Uchishandisa kushandisa kwake kwakakodzera, unogona kuwana mitezo yakaisvonaka.
Kuumbwa kweurea semugozi
Urea inowanzozivikanwa nezita remakemikari carbamide. Inonziwo carbonic acid diamid, asi mune imwe nzvimbo yakanyanyisa. Ogorodniki anozivawo kuti urea inoreva nitrogen-ine mushonga - 45% yehuwandu huwandu. Iyo yakagadzirwa kubva kune zvinhu zvisingabatanidzi uye ine maitiro akawanda ezvidzidzo. Makirasi machena kana akajeka echinhu ichi anopera mumvura uye anoshandiswa kunwisa uye kupomera kana kuti akawedzerwa kune ivhu munzvimbo yekutanga.
Basa reUrea?
Haasi munhu wose anoziva kuti rudzi rwemuti urea chii. Inoreva nitrogen fertilizer, iyo, zvichida, inofungidzirwa kunge inokosha muupenyu hwezvirimwa. Kupinda muvhu mune mararamiro emakristasi, iyo inoshandura inoshanduka kuva ammonium carbon dioxide kana gaseous ammonia. Ndiyo iye anonyatsoita zvose zvinomera zvinomera zvemuti. Saka, urea inozivikanwa nekuti iyo:
- inokurumidza kuparadzanisa kukanganisa kwemasero emiti, kusimbisa kukura;
- inovandudza kudya kwe nitrogen mumiti yakashata;
- kurwisana nezvipembenene zviduku;
- inogutsa pasi ne nitrogen.
Inguva yakadini urea ingachengetwa?
Irofu rehupenyu hwemajeri akadaro se urea hauna zvigaro. Kunyange zvazvo warranty period ndeye mwedzi mitanhatu pamapuranga. Inguva yakareba sei iyo fertilizer inogona kushandiswa inobva kune imwe nzvimbo yakawanda pane kuchengetedza. Chengetai urea mune chivharo chakanyatsovharwa kana zvipfeko zvisina kuvharwa.
Kana mushonga wacho uchinge uchitarisana nemhepo, zvino munguva inenge yakatarwa inotapurika iyo ichaderera zvikuru, uye saka, zvinobatsira zvinhu zvichaderera. Asi zvakadaro iwe unogona kushandisa urea nekusingaperi kwenguva refu.
Inguva ipi inova yakakodzera kushandisa urea?
Munhu wese anoziva kuti kuwandisa kwezvibereko mumunda kunogona kukanganisa zvinomera, pamwe nekuremara. Ndicho chikonzero nei zvakakosha kudyara mbeu ne urea sezvinodiwa uye zvakajeka zvishoma. Kuzadza bindu re "in reserve" hakugoni chero zvakadaro.
Asi pane mamiriro ezvinhu akaoma apo kushandiswa kusinganzwisisiki kweurea kunonzi kwakarurama. Iwe unofanirwa kuwana bhagi rinochengetwa nemakristasi apo unoona kuti mbeu:
- Usakure, uchive wakafanana nemamiriro ezvinhu sekudyara (inosangana nembeu yematamato, cucumber, eggplant, zucchini).
- Mashizha acho akatanga kutendeuka, akaoma kana kuwa.
- The ovary falls.
- Zvipembenene zvakaonekwa.
- Iko kune utera, huputika, mashizha mashoma, pane kuputsa kwemafotoynthesis.
Nzira yekushandisa urea semushonga?
Kushandiswa kweurea kuburikidza nekuputika pamusoro pepamusoro hakubatsiri. Mumazuva mashomanana, chirwere ichi, kana chichibatana nevhu chinyorwa, chinopinda mune gaseous state (ammonium carbonate) uye inongonyangarika. Ndicho chikonzero carbamide iri nani kupinda muvhu kana kuti zvishoma kudonhedzera. Mukuwedzera pakudururira granules, carbamide inoshandiswa muurudzi rwakavhiringidzirwa kukwira zvakananga kumudzi.
Kuberekwa kwemichero uye berry nemichero yemichero neUrea inotanga mukati megore uye kunopedza nguva yose yezvinomera. Munguva ino 3-4 marapirwo anowanzoitwa. Iwe unofanirwawo kuziva nezvenzvimbo yerea uine acidify ivhu , naizvozvo inokurudzirwa kuti iwe panguva imwechete uwedzere rima kune iyo (hafu yekisi ye urea - 0.4 kg yeaimu kana chaki).
Imwe mita yekubhiti yekudyara yemiti yakasiyana-siyana inoshandisa zvakasiyana-siyana zvechirwere:
- strawberries, strawberries - urea inotanga kupinda muvhu risati yadyara miche, yekudiridza panguva yekusviba, 5 gr ne 1 litre emvura inodiwa;
- kabichi, pepper, tomato, anyanisi, mbatatisi, garlic - 20-23 gr;
- zukini / squash uye eggplant - 10-12 gr;
- zviyo - 300 g pazana zana remunda;
- kutsvaira miriwo kubva kune zvidzvara uye zvirwere - kusvika 15 gr pa 10 malita emvura.
