Varimi vemizambiringa vanowanzodyisa zvimwe zvirimwa kuti zvive nezvirimwa zvakawanda. Kuti uite izvi, iwe unogona kushandisa makemikari, asi ipapo, zvose nitrate ndezvezvibereko. Izvo zvakachengeteka, asi zvisingaiti zvishoma, kushandisa zvakawanda zvinowedzera fertilizer, somuenzaniso urea kana carbamide .
Muchikamu chino, iwe uchadzidza pamusoro pekuumbwa kweurea, uye iyo inosima kushandiswa kwayo semuriwo mushonga unoshanda.
Chii chinonzi fertilizer urea chinosanganisira?
Urea ndiyo inonyanya kuiswa nitrogen fertilizer. Chiyero chechikemikari ichi chinenge 46% uye chiri mumamide fomu, iyo inowedzera nokukurumidza mumiti uye inotenderera kuburikidza nepamusoro pevhu.
Pfungwa ye urea
Mushure mekunge uwana huta iyi muvhu, pasi pekuita kwe enzymes, iyo inobudiswa nemaabhakitiriya anogara pasi, urea inoshanduka kuva ammonium carbonate. Munzvimbo umo mune basa rakakura rezvinyorwa, izvi zvinoshandiswa zvinotora mazuva maviri chete.
Urea inotengeswa semvura yakasanganiswa nemvura granules iyo keke mushure menguva inopera. Inogona kushandiswa zvakananga kune ivhu kana semhinduro.
Nzira yekukwanisa sei kugovera urea?
Urea inogona kushandiswa kune marudzi akasiyana-siyana ekudyisa, chete kuenzana kwekugadziriswa kwegadziriro yakaoma mumamita 10 emvura kuchasiyana:
- nokuti mudzi - 50-70 g;
- yezvirimwa zvemavara - 100 g.
Asi nokuda kwezvirimwa zvinomera, miti yemichero nemasango, zvakasiyana-siyana zvekushandiswa kwemuti uyu zvinosvibisa mufananidzo wakaoma zvinotsanangurwa.
Nzira yekushandisa urea semushonga?
Zvose zvinokurudzirwa nezvekushandiswa kweUrea kwemiriwo yezvirimwa ndizvo zvinotevera dhesi (inotangira 1 m2 yenyika):
- usati wasima - kusvika 12 g;
- munguva yekukura kwekushanda-kusvika 10 g;
- pamberi pemaruva - muchimiro chemhinduro, yakagadzirirwa muhuwandu hwa 50-60 g pa 10 malita emvura.
Pamiti uye shitubhi, zvose zvishongo nemichero-berry:
- munguva yekukura - 15-20 g;
- mushure memvura (shure kwemazuva 5-6) uye mushure memazuva makumi matatu - nechinangwa che20-30 g pa 10 malita emvura.
Usakanganwa kuti kudya kwe raspberries, tomato nemumanyorera uyu kunongobatsira chete.
Kana ukaunza urea, uchichiparadzira pasi pezvirimwa kana kuisa chisimbiso mugomba kana uchidyara pamwe navo, iva nechokwadi chekudira zvakanaka pashure.
Chii chandinofanira kutarisa kana uchishandisa urea?
Kana iwe uchida kushandiswa kweurea kuti uve nehuwandu hukuru, zvinotevera zvinofanira kuonekwa:
- Izvi zvinosarudzwa kuti zvive zvakasanganiswa neiyo, choko, dolomite uye nyore superphosphates, sezvo pane izvi zvakagadzirirwa basa ravo risina kubviswa, saka hakuzovi nemigumisiro.
- Munguva yekushandiswa kwayo, ivhu acidification rinoitika, naizvozvo, kuitira kuti usadzivisa simba rakaipa rakadaro remushonga, iyo inogarisana naro, rakatestone inofanira kuwedzerwa pachiyero che 1 kg ye urea kusvika 800 g yemaketone.
- Ammonium carbonate, yakawanikwa semugumisiro wekuparara kwewarea, iyo yakakanganiswa neoxygen decomposes, uye chikamu icho chinova gaseous, chinongorasika, izvo zvinoderedza huwandu hwehutano hwekushandiswa. Izvi zvinoitika apo urea inotanga muvhu rakavhurika risina kuiswa muvhu. Inofanirawo kuonekwa kuti pane alkaline uye neutongi hwevhu kusikirwa kwezvinhu zvakakosha zvemakemikari zvakakwirira kudarika zvimwe;
- Pamusana pekuti urea iri nani kudarika mamwe nitrogen fertilizer muvhu uye inonatswa zvishoma nezvishoma kubva kune mvura, inokurudzirwa kushandisa iyo munzvimbo iyo kunwa mvura inoshandiswa kana kuti kunyanyisa kunonyatsoonekwa.
