Initrogen ibaluleke kakhulu kwizityalo. Ngapha koko, ininzi kangangokuba ukuba abayifumananga emhlabeni apho iingcambu zabo zikhula khona, baya kuba neengxaki ezinkulu zokukhula.
Kodwa kubalulekile ukuba sikhumbule ukuba ukugqitha kwesi sondlo kunokuba yingozi kwizityalo zethu. Ke Masibone ukuba kubaluleke ngantoni, kwaye singazi njani ukuba isityalo sidinga i-nitrogen.
Yintoni initrogen?
Umjikelo wenitrogen
I-nitrogen yimichiza uphawu lwayo ngu-N. Ikho emoyeni womoya, ngepesenti ephezulu kakhulu (78%), nakwizinto eziphilayo. Ingathatha iintlobo ezininzi: umzekelo, emoyeni yirhasi, ngelixa Emhlabeni iyafumaneka kwizityalo ngohlobo lwe nitrate kunye nee nitrites.
Ukongeza, ikwakhona ekutyeni okuninzi okujolise ebantwini nasezilwanyaneni zabo, nakwichumisi nakwimigquba esetyenziselwa ukunyamekela izityalo.
Zifaka njani izityalo?
Lowo ngumbuzo onomdla kakhulu, kuba Initrogen eninzi ehlala izityalo ifunxwa ngumhlaba ovela kwiatmosfera. Kwaye idlula njani initrojeni ukusuka emoyeni ukuya emhlabeni? Ewe, zimbini iindlela: enye kukusebenzisa ii-microorganisms (ngokusisiseko ziibhaktiriya ezithi zivelise initrogen, okanye inoxanduva lokuyilungisa), kwaye enye yimvula kunye nezinye iimeko zemozulu.
Eyona ndlela isebenzayo neyona ikhawulezayo yeyokuqala, kuba njengoko sisazi ukuba ayina ndawo zonke kwindawo enye, kwaye kwiindawo ezininzi ayiwa nekhephu. Kodwa kukho ingxaki: ayizizo zonke iiplanethi iimeko ezifanelekileyo ukuba ii-microorganisms zivelise i-nitrogen ngokwaneleyo kwizityalo. Ke ngoko, kuhlala kufuneka ukubhenela kwizichumisi ukuze zikhule ngokwesiqhelo.
Ngoku, bayifumana njani? Ngokusebenzisa iingcambu, kwaye ukuya kuthi ga kwinqanaba elincinci ngokusebenzisa imingxunya yamagqabi.
Nguwuphi umsebenzi onawo kwizityalo?
Initrogen izalisekisa imisebenzi emininzi ebalulekileyo, kodwa inokushwankathelwa komnye: ukukhula. Kubalulekile ukuba iiseli zande kwaye, ngenxa yoko, zikwabalulekile kwizikhondo, iingcambu, amagqabi, ... ngamafutshane, onke amalungu esityalo angaqhubeka nokukhula. Ukongeza, ikwayimfuneko kakhulu kwimbewu, kuba enkosi kule khemikhali banokuhlala bephila ixesha elininzi okanye elingaphantsi de iimeko ezifanelekileyo zinikwe ukuba zihlume.
Ukuba sifuna ukubalula ngakumbi, singatsho ukuba initrogen Kuyimfuneko kwimveliso yeklorofili kunye nee-axins, kunye nokwenziwa kwe-lignin (icandelo lomthi elifumaneka emithini nasematyholweni).
Ziintoni iimpawu zokusilela okanye ukugqitha kwenitrogen kwizityalo?
Ngethamsanqa, njengoko oku kuyinto eyimfuneko kwizityalo, kulula kakhulu ukuyazi xa ilahlekile okanye ingaphezulu. Makhe sibone ukuba zithini iimpawu zetyala ngalinye:
- Ukungabikho kwe-nitrogen: amagqabi ajika abe tyheli eqala kulawo akudala, ukukhula kuyayeka, kwaye neziqu zinokuma.
- Ukugqithisa kweNitrogen: xa zininzi kakhulu zivelisa amagqabi agqithisileyo, ukukhula kungakhawuleza kodwa kodwa kube buthathaka, zithande izinambuzane, izifo, imbalela, njl.
Ngesi sizathu, Akulunganga ukungaphumeleli okanye ukugqitha. Kwenzeka into enye nangokunkcenkceshela: ukuba nje sidibanisa isixa samanzi abasifunayo kwaye ngalo lonke ixesha benxaniwe ngokwenene, baya kufakwa emanzini; kodwa ukuba sibagcinela umhlaba uhlala unamanzi, iingcambu zabo ziya kubola.
Iindidi zezichumisi ezizityebi nge nitrogen kwizityalo
Zininzi iintlobo zezichumisi ezityebileyo kwi-nitrogen, kodwa kuqala mandikuxelele ukuba kubaluleke kakhulu ukuba ulandele imiyalelo yosetyenziso onokuyifunda kwiphakheji yemveliso. Ngale nto ithethwayo, masibone ukuba zeziphi ezinye ezikhoyo phaya:
urea
I-Urea yifom yedayidi ye-carbonic acid, kwaye ke yimveliso ene-nitrogen ephezulu kakhulu: ngaphezulu kwe-46%. Ngesi sizathu, sincoma kuphela ukusetyenziswa kwayo xa izityalo zibonisa ukulibaziseka okukhulu ekukhuleni kwazo, kwaye zinamagqabi e-chlorotic.
Yithenge apha.
Ammonium nitrate
Akukho mveliso ifunyenweyo
Esi sisichumisi esinomxholo we-nitrogen ophakathi kwama-33 nama-34,5%Kule pesenti, isiqingatha yi-ammonia nitrogen kwaye enye i-50% yi-nitric nitrogen. Ke, kunomdla kakhulu ukuze izityalo zikhule ngokwesiqhelo, ukuba zisetyenziswa ngokufanelekileyo, ewe.
Yifumane Akukho mveliso ifunyenweyo.
Ammonium sulfate
Ammonium sulfate iqulethe nesalfure, ke ayiphelelanga nje kwisichumisi kodwa ikwangumngundo wokungunda kwanokuphucula iipropathi zemichiza yomhlaba ene-pH esisiseko okanye ye-alkaline (pH yesi-7 okanye ngaphezulu).

guano
El iguano Ngumgquba wemvelaphi yendalo, hayi ilize, lulindle lweentaka zaselwandle okanye amalulwane. Ukubunjwa kwayo kuyahluka ngokuxhomekeke kukutya kwesilwanyana, kunye neguano uqobo lwayo: kukutsha ngakumbi ngexesha lokuqokelelwa kwayo, ngakumbi initrogen eya kuba nayo, umzekelo.
Enye yezona zinto zibalaseleyo kwintengiso, ukusukela Ukongeza kwi-N iqulethe i-phosphorus, i-potassium, i-calcium, kunye ne-humic kunye ne-asidi ye-fulvic. Ewe kugxile kakhulu: nokuba kungokwemvelo, kufuneka uthathe idosi eboniswe kwisitya, nokuba kungangaphezulu okanye kungaphantsi; kungenjalo ziya kutshisa iingcambu.
Apha unayo ulwelo kwaye ungene esi sixhobo granulated. Yifumane.
Izichumisi zemichiza
Sigqibile ngemichiza. Ngokuqinisekileyo uvile okanye wathenga isichumiso esine-NPK, oko kukuthi, nge-nitrogen, i-phosphorus kunye ne-potassium. Ezi zezona zondlo zintathu zibaluleke kakhulu kwizityalo, yiyo loo nto izichumisi eziqulathe ipesenti enkulu okanye encinci zithengiswa emarikeni.
Umzekelo, isichumiso esiphindwe kathathu kwi-15 sine-15% ye-nitrogen, i-15% ye-phosphorus kunye ne-15% ye-potassium. Ukuba isichumisi esiyi-15-5-30, oko kuthetha ukuba sine-15% ye-nitrogen, i-5% ye-phosphorus kunye ne-30% ye-potassium. Kwaye ke wonke umntu. Ukusetyenziswa kwayo kunomdla xa sinodidi lwesityalo, njengomthi wesundu okanye icactus, kwaye sifuna ukusichumisa nemveliso ethile. yenzela Yean.
Ucinga ntoni ngalo mbandela? I-nitrojeni njengoko sibonile ibalulekile, kodwa ukugqitha kweli banga kunokubangela iingxaki ezinkulu kwizityalo, kuba zibenza babe buthathaka kwaye babesengozini kwizitshabalalisi nakwabanye. Siyathemba ukuba ufunde lukhulu malunga nale nto yemichiza kunye nendima yayo kubukumkani bezityalo.
