Feteleza.

Kodi nayitrogeni phosphorous potaziyamu feteleza ndi chiyani?

Nayitrogeni feteleza.

Mizu ya zomera imayamwa nayitrogeni feteleza.Nayitrogeni ndiye gawo lalikulu la mapuloteni (kuphatikiza ma enzymes ndi coenzymes), ma nucleic acid, ndi phospholipids.Ndi zigawo zofunika za protosotics, nucleons ndi biofilms ndipo zimagwira ntchito yofunika kwambiri pazochitika za moyo wa zomera.Nayitrojeni ndi chigawo cha chlorophylis, choncho chimagwirizana kwambiri ndi ntchito ya photosynthic.Miyezo ya nayitrogeni imakhudza mwachindunji kugawanika kwa maselo ndi kukula.Chifukwa chake, feteleza wa nayitrogeni ndizofunikira kwambiri.Urea, ammonium nitrate ndi ammonium sulphate amagwiritsidwa ntchito kwambiri paulimi.

Phosphate feteleza.

Phosphorus imalimbikitsa kukula kwa mizu, maluwa, mbewu ndi zipatso.Phosphorous imakhudzidwa ndi njira zosiyanasiyana za metabolic.Phosphorus ndi yochuluka mu minofu yogawanika ndipo imakhala ndi zopanga zambiri komanso zochita za moyo.Chifukwa chake, kugwiritsa ntchito feteleza wa phosphorous kumakhudzanso kukula kwa nthambi, nthambi ndi mizu.Phosphorous amalimbikitsa kutembenuka ndi kunyamula chakudya ndi kukula kwa mbewu, mizu ndi tubers.Ikhoza kuonjezera zokolola zambiri.

-Potash...

Potash amagwiritsidwa ntchito kulimbikitsa kukula kwa tsinde, kutuluka kwa chinyezi ndi zotsatira zamaluwa.Potaziyamu (K) amakhazikika muzomera mu mawonekedwe a ayoni m'malo ochulukira kwambiri a moyo wa mmera, monga malo okulirapo, magawo opangira, ndi masamba.Potaziyamu imalimbikitsa kaphatikizidwe ka mapuloteni ndi kayendedwe ka shuga kuti zitsimikizire kuyamwa kwa magazi kuchokera ku maselo.

Ubwino wa feteleza.

Feteleza amathandiza zomera kukula
Amakhala ndi michere imodzi kapena zingapo zofunika kuti zikule, monga nayitrogeni, phosphorous, potaziyamu ndi zinthu zina zosiyanasiyana.Akauika m’nthaka, zakudyazi zimatha kukwaniritsa zofunika pakukula kwa zomera, kuzipatsa zakudya zomwe zilibe, kapena kuwathandiza kuti asunge zakudya zotayika.Feteleza amapereka feteleza wa nayitrogeni ndi phosphorous potaziyamu kuti athetsere dothi losadyetsedwa bwino ndi zomera.

Feteleza ndi wotsika mtengo kuposa fetereza wamba.

Feteleza nthawi zambiri ndi wotsika mtengo kuposa feteleza wamba.Kumbali imodzi, kuchokera pakupanga feteleza wachilengedwe, sizovuta kudziwa chifukwa chake feteleza wachilengedwe ndi wokwera mtengo: kufunikira kwamitengo yokwera kuti mupeze zopangira zopangira feteleza wachilengedwe, komanso chiphaso cha boma cha organic certification. za mtengo wokwera mtengo.

Feteleza, kumbali ina, ndi yotsika mtengo chifukwa imakhala ndi zakudya zambiri pa kilogalamu ya kulemera kwake, pamene zakudya zomwezo zimafuna feteleza wambiri.Nthawi zambiri pamafunika mapaundi angapo a feteleza wachilengedwe kuti apereke milingo yofanana ya michere ya nthaka ngati paundi imodzi ya feteleza.Zifukwa ziwirizi zimakhudza mwachindunji kugwiritsa ntchito feteleza ndi feteleza wachilengedwe.Malipoti ena akuwonetsa kuti msika wa feteleza waku US uli pafupifupi $40 biliyoni, pomwe feteleza wachilengedwe amangotenga pafupifupi $60 miliyoni.Chotsalacho ndi gawo la mitundu yonse ya feteleza opangidwa ndi anthu.

More mwachindunji kupereka zakudya zofunika kwa mbewu.

Kupereka zakudya mwachangu komanso kutsika mtengo kogulira zinthu kwapangitsa kuti feteleza azigwiritsidwa ntchito kwambiri.Feteleza wakhala chisankho chachikulu m'minda yambiri, mabwalo ndi minda komanso gawo lofunikira pakukonza udzu watsiku ndi tsiku.Koma kodi feteleza adzawononga nthaka ndi zomera?Kodi tiyenera kulabadira chiyani pa ntchito fetereza??

Mavuto azachilengedwe obwera chifukwa chogwiritsa ntchito feteleza.

Kuipitsidwa kwa madzi apansi panthaka.

Zinthu zina zomwe zimagwiritsidwa ntchito popanga feteleza zimatha kusokoneza chilengedwe zikangolowa m'madzi apansi panthaka.Nayitrogeni yochokera m'minda yomwe imayenderera m'madzi apansi panthaka imapanga 51% ya zochita za anthu.Ammonia nayitrogeni ndi nayitrogeni wa nayitrogeni ndizo zowononga kwambiri m'mitsinje ndi nyanja, ndipo ndizo zomwe zimayambitsa kuwonongeka kwa madzi ndi kuipitsidwa kwa madzi pansi.

Kuwonongeka kwa dothi
Ndi kugwiritsa ntchito feteleza nthawi yayitali, acidification ya nthaka, khungu ndi zovuta zina zachilengedwe.Chifukwa cha kuchuluka kwa nayitrogeni fetereza osati organic fetereza, chifukwa ena otentha munda nthaka khungu kwambiri, ndipo pamapeto pake kuchititsa imfa ya ulimi mtengo wa nthaka.Zotsatira za feteleza m'nthaka sizingasinthe.

Kugwiritsa ntchito feteleza kwa nthawi yayitali kumasintha pH ya nthaka, kumawononga zachilengedwe zopindulitsa, kumawonjezera tizirombo komanso kutulutsa mpweya wowonjezera kutentha.

Mitundu yambiri ya feteleza imakhala ndi acidic kwambiri, zomwe zimapangitsa kuti nthaka ikhale ndi acidity, potero imachepetsa zamoyo zopindulitsa ndikulepheretsa kukula kwa mbewu.Mwa kuwononga chilengedwe chachilengedwechi, kugwiritsa ntchito feteleza opangira kwa nthawi yayitali kumatha kuyambitsa kusalinganika kwamankhwala m'zomera zolandirira.

Kugwiritsanso ntchito kungapangitse kuti m'nthaka muunjike mankhwala oopsa monga arsenic, cadmium ndi uranium.Mankhwala oopsawa amatha kulowa mu zipatso ndi ndiwo zamasamba.

Pali kumvetsetsa kwina kwa kugwiritsa ntchito feteleza ndipo kungapewedwe pogula fetereza.

Kutaya kosafunikira kungathenso kuonjezera zokolola.

Gwiritsani ntchito feteleza moyenera.

Feteleza ndi lupanga lakuthwa konsekonse.Ndizopindulitsa komanso zowononga, malingana ndi kuchuluka kwa ntchito ...Feteleza amasankhidwa malinga ndi momwe nthaka ilili.

Musanagule fetereza, dziwani nthaka pH.Ngati nthaka ili acidic, kuchuluka kwa feteleza wachilengedwe kumatha kuonjezedwa, kuwongolera kwa nayitrogeni kumatha kusungidwa, komanso kuchuluka kwa feteleza wa phosphorous kuyenera kusungidwa.

Kuphatikiza feteleza ndi organic fetereza.

Kugwiritsa ntchito feteleza wachilengedwe ndi feteleza ndikofunikira pakupanga ulimi.Kafukufuku akuwonetsa kuti ndizopindulitsa pakusintha kwa organic matter.Pogwiritsa ntchito feteleza ndi feteleza wachilengedwe, kukonzanso kwa zinthu za m'nthaka komanso kusinthika kwa kusinthana kwa nthaka kungathandize kupititsa patsogolo ntchito ya michere ya nthaka ndikuwonjezera kuyamwa kwa michere mu mbewu.Zimathandizira kukulitsa mtundu wa mbewu, kuonjezera zomanga thupi, ma amino acid ndi michere ina, komanso kuchepetsa zomwe zili mu nitrates ndi nitrites mumasamba ndi zipatso.Sankhani njira yoyenera ya umuna.

Pankhani ya njira za feteleza ndi chilengedwe, nitrate zili m'masamba ndi mbewu zimagwirizana kwambiri ndi mitundu ya nayitrogeni ya nthaka.Kuchuluka kwa nayitrogeni m'nthaka, m'pamenenso masamba amasamba amachulukirachulukira, makamaka m'magawo amtsogolo.Choncho, ntchito fetereza ayenera oyambirira, osati kwambiri.Feteleza wa nayitrogeni sayenera kuwazidwa, apo ayi angayambitse kusakhazikika kapena kutayika.Chifukwa mayendedwe a phosphorous fetereza ndi otsika, ayenera kukwiriridwa mozama ndi ntchito.

Feteleza amakhudzanso kwambiri chilengedwe.

Feteleza ali ndi chiwopsezo cha kuipitsidwa ndi madzi apansi panthaka ndi zovuta za nthaka zomwe zimayambitsa.Chotero tiyenera kumvetsetsa zimene zikuchitika ku nthaka ya pansi pa mapazi athu kotero kuti tithe kupanga chosankha choyenera mwachikumbumtima.

Mfundo ya umuna.

Chepetsani kuchuluka kwa feteleza wogwiritsidwa ntchito, pogwiritsa ntchito feteleza wachilengedwe.Kuzindikira kwa zakudya zopatsa thanzi kumachitika molingana ndi momwe nthaka ilili ndipo umuna umachitika molingana ndi zosowa zenizeni.Kuchita molingana ndi nthawi, malinga ndi momwe zinthu zilili m'deralo kuteteza chilengedwe.
