Nitrogen yakanyanya, yakakosha kumiti. Muchokwadi, zvakanyanya zvekuti dai vasina kuzviwana muvhu mune midzi yavo, vangave nematambudziko akakura ekukura.
Asi zvakakoshawo kuti titarise mupfungwa kuti kuwanda kwechikafu ichi kunogona kukuvadza zvirimwa zvedu. Saka ngatione kukosha kwayo, uye tingazive sei kuti chirimwa chinoda nitrogen.
Chii chinonzi nitrogen?
Kutenderera kwe nitrogen
Nitrogen kemikari ine mucherechedzo ndiN.Iyo irimo mumhepo yemuchadenga, mune yakakwira kwazvo muzana (78%), pamwe nevezvinhu zvipenyu. Inogona kutora mafomu akati wandei: semuenzaniso, mumhepo igasi, nepo muvhu inowanikwa zvirimwa nenzira ye nitrate uye nitrites.
Mukuwedzera, iripowo muzvikafu zvakawanda zvakagadzirirwa vanhu nezvipfuyo zvavo, pamwe nemafetireza nemanyowa ayo anoshandiswa kuchengetedza zvirimwa.
Zvirimwa zvinozviisa sei?
Iwo mubvunzo unonakidza kwazvo, nekuti yakawanda yenitrogen inosara ichiwanika kumiti inonwiwa nevhu kubva mudenga. Uye sei nitrogen inopfuura kubva mumhepo ichienda pasi? Huye, pane nzira mbiri: imwe iri kuburikidza nema microorganisms (hazvo iwo mabhakitiriya anogona kuburitsa nitrogen, kana ane basa nekuigadzirisa), uye imwe yacho ndeyekunaya kwemvura uye zvimwe zviitiko zvemamiriro ekunze.
Nzira inoshanda nekuchimbidza ndiyo yekutanga, nekuti sekuziva kwedu haina kunaya munzvimbo dzese ine frequency yakafanana, uye munzvimbo zhinji haina kana kudonha sinou. Asi pane dambudziko: hadzisi pasi rese mamiriro akakodzera ema microorganisms kuburitsa nitrogen muhuwandu hwakakwana hwezvirimwa. Neichi chikonzero, zvinowanzo fanirwa kuenda kune fetiraiza kuitira kuti vakure zvakajairika.
Zvino, vanozvifambisa sei? Kubudikidza nemidzi, uye kusvika padiki padiki nepasi pemashizha.
Ibasa ripi raanaro muzvirimwa?
Nitrogen inozadzisa akati wandei akakosha mabasa, asi iwo anogona kupfupikiswa mune rimwe: kukura. Izvo zvakakosha kuti maseru awande uye, nekudaro, zvakare zvakakosha kuti madzinde, midzi, mashizha, ... muchidimbu, zvikamu zvese zvemuti zvinogona kuramba zvichikura uye kukura. Uye zvakare, iyo inodawo kwazvo kune mbeu, nekuti nekuda kwekemikari iyi vanogona kuramba vari vapenyu kwenguva yakati rebei kana kushoma kusvikira mamiriro akakodzera apihwa kumera.
Kana tichida kunyatso tsanangura, tinogona kuti nitrogen iyo inofanirwa kugadzirwa kweklorophyll uye auxins, pamwe nekuumbwa kwe lignin (chinhu chehuni chinowanikwa mumiti nemakwenzi).
Ndezvipi zviratidzo zvekushayikwa kana kuwandisa kwe nitrogen muzvirimwa?
Neraki, sezvo ichi chiri chinhu chakakosha pazvirimwa, zviri nyore kuziva kana chisipo kana chakawandisa. Ngatione kuti ndezvipi zviratidzo mune imwe neimwe kesi:
- Kushaya nitrogen: mashizha anochinja kuita yero kutanga neyakare, kukura kunomira, uye madzinde anogona kumira.
- Nitrogen yakawandisa: kana vaine zvakawandisa vanogadzira kuwandisa kwemashizha, kukura pamwe nekukurumidza asi zvakare kusimba, vanonyanya kutapukira kuzvipukanana, zvirwere, kusanaya kwemvura, nezvimwe.
Neichi chikonzero, Hazvina kunaka kana kutadza kana kuzvipfuudza. Chinhu chimwe chete ichi chinoitika nekudiridza: chero bedzi isu tichiwedzera huwandu hwemvura yavanoda uye pese pavanove nenyota chaiyo, vanozove vakagirwa asi kana tikachengeta ivhu kwavari nguva dzose rakazara nemvura, midzi yavo inoora.
Mhando dzefetiraiza dzakapfuma mu nitrogen yezvirimwa
Kune mhando dzakawanda dzefetiraiza dzakapfuma mu nitrogen, asi chekutanga regai ndikuudzei kuti zvakakosha kuti utevedze rairo dzekushandisa dzaunogona kuverenga pane zvigadzirwa zvakagadzirwa. Nezvo zvataurwa, ngatione kuti ndeapi mamwe evari kunze uko:
urea
Urea idhaimidhi fomu yecarbonic acid, uye nekudaro ndicho chigadzirwa chine yakanyanya senitrogen yevasungwa: inopfuura 46%. Nechikonzero ichi, isu tinongokurudzira kushandiswa kwayo kana zvirimwa zvichiratidza kunonoka kukuru mukukura kwavo, uye zvakare zvine machlorotic mashizha.
Tenga icho pano.
Ammonium nitrate
Hapana zvigadzirwa zvakawanikwa.
Iyi fetiraiza ine nitrogen iri pakati pe33 ne 34,5%Kubva muzana iro, hafu iammonia nitrogen uye imwe 50% nitric nitrogen. Nekudaro, zvinonakidza kwazvo kuti zvirimwa zvikure zvakajairika, chero bedzi zvichishandiswa zvine mutsindo, ehe.
Tora kubva Hapana zvigadzirwa zvakawanikwa..
Ammonium sulfate
Ammonium sulfate iine sulphur, saka haisi yakanaka chete sefotereza asi zvakare sefungicide uye kunyangwe kunatsiridza makemikari eivhu ine basic kana alkaline pH (pH ye7 kana kupfuura).
Unoda here? Dzvanya pano.
guano
El guano Ndiwo manyowa emanyowa, kwete pasina, iwo tsvina yemhashu dzegungwa kana zviremwaremwa. Kuumbwa kwaro kunosiyana zvichienderana nekudya kwemhuka, pamwe neguano pachayo: ichinyatsonaka panguva yekuunganidzwa kwayo, inowedzera nitrogen, semuenzaniso.
Iyo ndeimwe yeakanakisa pamusika, kubvira Mukuwedzera kune N ine phosphorus, potasium, calcium, pamwe nehumic uye fulvic acids. Ehe, yakanyanyisa kukosheswa: kunyangwe kana iri yechisikigo, iwe unofanirwa kutora muyero unoratidzwa pamudziyo, kwete zvakanyanya kana zvishoma; zvikasadaro midzi ichapisa.
Pano unayo mvura uye mukati Iyi link granulated. Zvitore.
Makemikari manyowa
Isu tapedza nemakemikari. Chokwadi iwe wakambonzwa nezvayo, kana kuti ungatotenga fetiraiza ine NPK, ndiko kuti, ine nitrogen, phosphorus uye potasium. Aya ndiwo matatu akakosha zvinovaka muviri kuzvirimwa, ndosaka mafetiraiza ane iwo muzvikamu zvikuru kana zvishoma achitengeswa pamusika.
Semuenzaniso, katatu 15 fetiraiza ine 15% nitrogen, 15% phosphorus uye 15% potasium. Kana iri fotereza 15-5-30, zvinoreva kuti ine 15% nitrogen, 5% phosphorus uye 30% potasium. Uye saka nemunhu wese. Kushandiswa kwaro kunonakidza kana isu tine mhando yemuti, senge muchindwe kana cactus, uye isu tinoda kuisanganisa nechimwe chigadzirwa. kwaari.
Iwe wafungei nezvenyaya iyi? Nitrogen sezvataona yakakosha, asi kuwanda kwechinhu ichi kunogona kukonzera matambudziko akakura kumiti, nekuti inovaita vasina simba uye vanotambura nezvipembenene nevamwe. Tinovimba wakadzidza zvakawanda nezve ichi chemakemikari chinhu uye basa rayo muumambo humambo.
