Onse agrarians, onse odziwa ndi a novice, amadziwa za urea (carbamide). Iyi ndi feteleza yodalirika komanso yothandiza kwambiri m'munda. Lero tidzanena kuti: Kodi urea ndi malamulo otani ngati akugwiritsa ntchito feteleza komanso momwe mungagwiritsire ntchito mankhwala ophera tizilombo m'munda ndi urea?
Kodi urea ndi chiyani?
Urea (urea) - nayitrogeni feteleza mu granules, omwe amagwiritsidwa ntchito kwambiri mu horticulture ndi horticulture, kuwonjezera, ndi yotchipa komanso yotsika mtengo.
Ngati mumagwiritsa ntchito mlingo woyenera wa urea monga feteleza pa mbeu inayake, zomera zimakula bwino, zimakula, ndikubala zipatso zambiri.
Urea mu mawonekedwe ake oyera - azungu zoyera kapena zosaoneka bwino granules, ndipo ndendende kuti izo zimapangidwa mu granules, sizimalola kuti zizimitse panthawi yopita ndi kusungirako. (NH2)2CO ndi mankhwala a urea, omwe pafupifupi theka, ndiwo 46 peresenti ya zonse, ndi nayitrogeni.
Mukudziwa? E927b - chakudya chowonjezera ndi urea, chomwe chimagwiritsidwa ntchito popanga chingamu.Urea imasungunuka m'madzi ambiri otchuka, kuphatikizapo madzi wamba, omwe amathandiza kuti azigwiritsire ntchito moyenera (mu granules) ndi mawonekedwe a madzi omwe amafunidwa.
Ndikofunikira! Urea ayenera kutetezedwa mosamalitsa ku chinyezi panthawi yosungirako, chifukwa ndi wouma kwambiri.
Zizindikiro za kusowa kwa nayitrogeni mu zomera
Pansi panthaka, mbande zimakhudzidwa ndi zinthu zosiyanasiyana, ngakhale zitakhala zolimba pa mmera. Ngati palibe nayitrogeni yokwanira m'nthaka, ndithudi mudzawona izi mu zomera, malingana ndi zizindikiro zina:
- Chocheperapo, chodandaula chomera chomera.
- Zofooka kwambiri, zochepa ndi zazifupi za mitengo ndi zitsamba.
- Masamba pa zomera ndi ang'ono ndi opapatiza, obiriwira obiriwira (otumbululuka) mu mtundu, kapena ngakhale wooneka ngati chikasu. Kwa zomera zosowa nayitrogeni, masamba akhoza kugwa mofulumira kwambiri.
- Mitengo ya maluwa imakhala yosasinthika ndi yofooka, ndi yaying'ono kwambiri kuposa momwe iyenera kukhalira, mtengowo umapweteketsa bwino.
Ndikofunikira! Kuwonjezera pa nayitrogeni m'mitengo ndizoopsa kwambiri, zikhoza kutembenuzidwa kukhala nitrates, komanso feteleza feteleza m'nthaka zimabweretsa kukula kwa zomera ndi mapangidwe ambiri a zomera, koma fructification imavutika.
Kugwiritsa ntchito urea monga feteleza
Urea ndi yoyenera pa njira zonse ndi njira zogwiritsira ntchito (nthawi yofesa, musanafese, panthawi ya kukula kwa zomera, foliar kudya pamaso pa ovary chipatso).
Urea amagwiritsidwa ntchito monga feteleza wamkulu asanabzala pa mitundu yonse ya dothi ndikudyetsa masamba, zokongola ndi zipatso za mbewu. Ikhoza kugwiritsidwanso ntchito pa malo otetezedwa.
Chochititsa chidwi! Dzina la gulu la mpira wa Amkar kuchokera ku Perm ndi chidule cha mankhwala awiri, ammonia ndi carbamide.
Mizu yophika
Kawirikawiri, chithandizo chamtundu wa zomera ndi urea chimatanthawuza kuti chimayambira pansi, ndipo chimapangidwanso mozama.
Kubalalitsa galauleti ya carbamide panthawi yamvula sikungapindule kwambiri.Choncho, ndibwino kugwiritsira ntchito ntchito yowonongeka - njira yothetsera urea yomwe inakonzedweratu kwa munda wamaluwa ndi madzi okwanira akhoza kutsanuliridwa pafupi kwambiri ndi mizu.
Pakuti strawberries, nkhaka, tomato, kabichi, yankho lapangidwa 20-30 g wa urea pa 10 malita a madzi, kwa gooseberries -10 g wa urea pa 10 malita a madzi, ndi currants -20 g wa urea pa 10 malita a madzi.
Njira yachiwiri imagwiritsidwanso ntchito - kukumba mabowo kapena mazenera ang'onoang'ono omwe umagwiritsidwa ntchito urea, kutsanulira pa iwo ndikutsanuliridwa ndi madzi. Njira yoyamba ndi yabwino kugwiritsa ntchito nyengo yowuma, ndipo yachiwiri - mvula. Pakuti zipatso zomera, carbamide akuwonjezeredwa molingana ndi kuyerekezera awo korona.
Mitengo ya Apple imalimbikitsidwa kupatsa 200 g feteleza pa mtengo uliwonse, ndi yamatcheri ndi plums mpaka 140 g.
Ndikofunikira! Ngati mitengo ili yaying'ono ndipo isabereke chipatso, ndiye kuti urea uyenera kukhala wochepa, ndipo ngati mankhwala amagwiritsidwa ntchito, osachepera limodzi mwa magawo atatu.
Processing Foliar
Mwamsanga pamene oyamba akuonekera zizindikiro za njala ya nayitrogeni mu zomera, nkofunikira kuchita foliar kupopera mankhwala zomera ndi njira yothetsera urea pogwiritsira ntchito dzanja lamankhwala madzulo kapena m'mawa.
Ngati palibe sprayer, ndiye chithandizochi chikhoza kuchitika ndi tsache losavuta. Njira yothetsera feteleza zamasamba zimapangidwa ndi mlingo wa 60 g wa urea 10 malita a madzi, ndi zipatso za mbeu - 30 g wa urea pa 10 malita a madzi, ndipo njira iyi sichiwotcha masamba, omwe sitinganene za ammonium nitrate.
Ndikofunikira! Ngati pali mphepo kunja (mwachitsanzo, mvula), ndiye simungagwiritse ntchito carbamide kuti muveke zovala.
Urea motsutsana ndi tizirombo m'munda
Urea wapeza kuti amagwiritsidwa ntchito m'munda komanso m'munda wothandizira wabwino mu tizilombo toyambitsa matenda, ndipo ngati palibe chilakolako chogwiritsa ntchito mankhwala ophera tizilombo, tidzakhala bwino.
Kwa ichi m'pofunika kupopera zomera ndi urea yankho, impso zisanakhalepo, ndipo kutentha kwa mpweya kunja kwafikira + 5 ° ะก.
Kupopera mbewu mankhwala anachita motere: pa 1 l madzi - 50-70 g wa urea, komanso njira yothetsera (1 l madzi - oposa 100 g wa urea) sayenera kuchitidwa kuti asatenthe masamba.
Njirayi idzakuthandizani kuthetsa zozizira zazing'ono (weevils, aphid, sucker ndi zina).
Mwa kupopera mbewu zomera ndi njira yomweyi monga tizilombo toyambitsa matenda, mungathe kuwateteza nkhanambo, bulauni, ndi matenda ena opatsirana. Ingochita izo molondola m'dzinjam'masiku oyambirira a tsamba kugwa.
