Mavitamini a feteleza ndi chiyani?

Mavitrogeni monga gwero la zakudya zamasamba amapezeka mwachilengedwe m'nthaka, koma m'madera osiyanasiyana nyengo zimakhala zosiyana. Nitrojeni yaying'ono yokongola kwambiri m'mapapu a dothi la mchenga ndi lachinyontho loamy. Kuonjezerapo, 1 peresenti yokha ya mankhwalawa ndi zomera, kotero ndikofunikira kuti nthawi zonse likhale lopindulitsa nthaka ndi feteleza zamchere, ndipo ndi feteleza ati omwe tikambirane m'nkhaniyi.

Kufunika kwa feteleza feteleza kwa zomera

Zakudya za nayitrogeni zapamwamba zimangokhala ndi zotsatira zabwino pa zokolola, komanso zimapangitsa kuti mbewu zowonjezereka zikhale zabwino. Chifukwa cha kuchulukitsa kuchuluka kwa mapuloteni ndikukula mapuloteni ofunikira kwambiri, zomera zomwe zimamera zimayamba kukula mofulumira, masamba awo amadziwika ndi mdima wobiriwira, ndipo zipatso zake ndi zazikulu. Ngati nayitrojeni sikokwanira, ndiye mbali yomwe ili pamwambayi ilibe klorophyll ndipo masamba amakula pang'ono, amataya mtundu, ndipo zokolola zimagwa. Mulole kufooka kwa mapuloteni ndi mbewu. Choncho, ndikofunikira kupanga zofunikira pakukonzekera mbeu, ndikupatsa nthaka ndi nitrojeni yofunikira.

Organic nayitrogeni feteleza

Zikuphatikizapo:

1. Mitundu yonse ya manyowa, zitosi za mbalame, makamaka bakha, nkhuku ndi njiwa.
2. Kompositi imatha. Nitrojeni yaying'ono imapezeka mu milu ndi zinyalala zapanyumba.
3. Mdima wobiriwira. Amakhalanso ndi masamba, nyanja silt, lupine, sweet clover, vetch, clover, ndi zina zotero.

Mavitamini a feteleza amchere

Amene amafunsa dzina la nitrojeni feteleza, ndiyenera kumvetsera mndandanda uwu:

1. Ammonium feteleza ndi ammonium sulfate, ammonium chloride.
2. Nitrate feteleza ndi calcium ndi sodium nitrate.
3. Manyowa amide ndi urea .

Izi zimagwiritsidwa ntchito pa feteleza zamchere. Pogulitsa mukhoza kupeza ndi feteleza, okhala nayitrogeni nthawi imodzi mu nitrate ndi ammonia mawonekedwe. Kuwonjezera apo, m'pofunika kudziwa kuti feteleza feteleza amagwiritsidwa ntchito phosphorous ndi feteleza feteleza. Zofunikira zimenezi zimagwiridwa ndi superphosphate, fupa kapena dolomite ufa, ammonium nitrate. Zomalizazi zimagwiritsidwa ntchito pa malo ochepa omwe ali ndi humidified ndi nthaka yothetsera mavuto. Nthawi zambiri zimasakanizidwa ndi superphosphate ndi wothandizira. Izi zimaganizira mtundu wa mbewu zowalidwa, chifukwa digiri ndi njira yowonjezeretsa nayitrogeni mwazosiyana.

Pa mafakitale, madzi a nayitrojeni feteleza amagwiritsidwa ntchito, omwe amagawidwa mofanana, amathandizidwa bwino ndikugwira ntchito kwa nthawi yaitali. Komabe, nitrojeni yokwanira yopatsa zomera ingathe kukhazikitsidwa kokha ndi kugwiritsidwa ntchito kovuta kwa feteleza ndi organic ndi feteleza.
