Mavitrogeni m'nthaka ndi chinthu chofunikira kwambiri pa chitukuko cha zomera. Amafunika mochuluka ndipo ayenera kuwonjezeredwa ku nthaka kuti asapewe kusowa . Nayitrogeni ndi mbali yaikulu ya chlorophyll ndi zomera zobiriwira. Ndili ndi udindo waukulu wokula komanso kukula kwa udzu wokongola, wokongola. Ngakhale kuti nayitrojeni ndi chinthu chochuluka kwambiri m'mlengalengalenga, zomera sizikhoza kuzigwiritsa ntchito mpaka mwachibadwa zimakonzedwa m'nthaka kapena kuwonjezeredwa monga feteleza .
Mavitrogeni Owonjezera ndi Kulephera
Kuchuluka kwa nayitrogeni, chifukwa cha feteleza pamapeto, kungayambitse kukula kofulumira, kwakukulu ndi mizu yochepa. Nthawi zambiri, kumasulidwa mwamsanga kwa nayitrogeni kungayambitse kutentha kwa masamba, ndi kubzala imfa. Udzu wokhala ndi vuto la nayitrogeni umataya mtundu wake wobiriwira ndikuyamba kutembenuka.
Mtsinje wa Nitrogeni
Nayitrogeni ikhoza kudutsa kusintha kwakukulu m'nthaka. Zosinthazi nthawi zambiri zimagawidwa mu dongosolo lotchedwa nayitrojeni, yomwe ikhoza kuwonetsedwa mosiyanasiyana. Ndondomeko ya nayitrogeni ndi yoyenera kumvetsetsa kayendetsedwe ka umoyo ndi feteleza. Chifukwa tizilombo toyambitsa matenda ndi omwe amayambitsa njira zambiri, zimakhala zochepa pang'onopang'ono, ngati pena kutentha kwa nthaka kuli pansi pa 50 ° F, koma mitengo yawo imakula mofulumira ngati dothi limakhala lofunda.
Mavitrogeni
Zida Zamagulu:
- manyowa
- yowonjezera sewer sludge (Milorganite)
- zina zopangidwa monga mankhwala a manyowa, nsomba, ndi guano
Nitrogeni yamoyo kapena mwachibadwa ndizochokera kwa tizilombo toyambitsa matenda. Njirayi ndiwowonjezereka ndikupulumutsidwa popanda vuto la leaching. Manyowa opangidwa ndi feteleza ali ndi zotsika kwambiri zotentha kotero palibe pangozi ya chovulala chomera kuchoka pamagwiritsidwe ntchito.
Kugwiritsira ntchito nayitrojeni yamtunduwu kumameretsa nthaka yathanzi osati kungodyetsa zomera.
Zosowa zachilengedwe:
- ammonium nitrate
- calcium nitrate
- ammonium sulphate
Nitrojeni yosakanikirana imachokera ku mchere ndipo imayenera kuyanjana ndi mankhwala ena. Ndikusungunuka kwa madzi, kuwalola kuti ipeze nthawi yomweyo pammera pa kuthirira. Kugwiritsira ntchito nayitrogeni yokhayo kumapereka zotsatira zofulumira, komanso kumakhala ndi mphamvu yotentha kwambiri ngati itagwiritsidwa ntchito. Nitrates imalowanso mu nthaka mofulumira komanso osagwiritsidwa ntchito ndalama zimatha kuipitsa madzi pansi, kotero pali chiopsezo chachikulu pogwiritsa ntchito nayitrogeni
Zosakaniza:
- Sulfur-coated urea
- Resin-coated urea
- Isobutylidene diurea (IBDU)
Mavitamini a nayitrogeni amatha kukhala ngati urea kapena urea. Pokhapokha, urea akumasula mofulumira katundu koma akhoza kusinthidwa ndikuphatikizidwa ndi zipangizo zina kuti pang'onopang'ono kumasulidwe. Chophimba chimagwiritsidwa ntchito ku urea, kuti pang'onopang'ono kumasulidwe kumadalira kukula kwake, kutentha, ndi chinyezi cha nthaka.
Manyowa ambiri adzakhala ndi mndandanda wa zitsamba za nayitrogeni zowonjezera zobiriwira, ndi kupititsa patsogolo pang'ono, kutulutsa pang'onopang'ono. Chiŵerengero kapena peresenti, ya chitsime chilichonse cha nayitrogeni, chiri pa chizindikiro.
Zotsatira za Chilengedwe
Pali kutsutsana ndi kugwiritsidwa ntchito kwa nayitrogeni.
Kugwiritsa ntchito mobwerezabwereza kumabweretsa kusokoneza madzi pamtunda pogwiritsa ntchito zida zowonongeka. Kugwiritsa ntchito mafuta ambiri mu kupanga ndi kukonza feteleza zopangidwa ndi nayitrogeni ndi chifukwa chodandaula. Malinga ndi msinkhu wanu woyendetsa zachilengedwe, mukhoza kukanika ndi zitsulo za nitrogen. Ngati mumagwiritsa ntchito zowonongeka ndi / kapena zachilengedwe, musagwiritse ntchito. Werengani lembalo ndikutsatira ndondomekoyo monga momwe yasonyezera.
