Mazuva ano, kuwana zvirimwa zvinopa zvakawanda uye zvirinyore zviri nyore. Tine zvatinazvo zvakasiyana siyana zvefetiraiza nefetiraiza izvo, chero zvichishandiswa nenzira kwayo uye panguva kwayo, zvinotibvumidza kuwana izvo zvatinoda zvakanyanya. Imwe yacho ndeye calcium nitrate, inova yakakwana kuti zvirimwa zvikure zvese zvavanazvo kuti zvikure.
Uye ndezvekuti kunyangwe vasingakwanise kushaya mvura, sevapenyu havagone kushaya zvinovaka muviri, uye calcium ndiyo imwe yezvakanyanya kukosha kuti vakure zvakajairika.
Chii?
Calcium nitrate chinhu chisina kujairika (ndiko kuti, hachiuye kubva kune chero munhu mupenyu) iyo inonziwo Norwegian nitrate yeimu. Rudzi rwemunyu usina kana ruvara kana rine mvura uye unoshandiswa zvakanyanya mukurima, nekuti unowanikwa mufetireza zhinji. Muchokwadi, zvinonakidza kwazvo kuti zvirimwa zvikure zvine simba, sezvo calcium iri imwe yemaminerari anoshandiswa nemasero kuzvikamura uye kuzvisimbisa.
Iyo fomula ndeye Ca (NO3) 2. Unogona kunge wakambozviona kamwe kana watenga imwe yekutarisira zvirimwa zvako. Uye zviri nyore kwazvo kuzviwana munzvimbo dzekuchengetera uye muzvitoro zvebindu; chimwe chinhu chiri pasina mubvunzo chinonakidza nekuti zvinoreva kuti tinogona kuchiwana pese patinochida.
Kuumbwa kwe calcium nitrate
Izvo zvakakosha kuti uzive kuumbwa kwefetiraiza inotengwa, nekuti nenzira iyi tinogona kuishandisa zvirinani. Muchiitiko checalcium nitrate, ayo akaumbwa ese anotevera:
- Nitrogen (N): pakati pe14,5 ne15.5%. Kupfuura makumi mapfumbamwe muzana ezve nitrogen ese anowanzo ari mune nitric fomu, nemamwe ese ari muchimiro cheammonia nitrogen.
- Calcio (CaO): pakati pe26 uye 27%
Inogona kusiyana muzvidimbu zvichienderana nemugadziri, asi zvishoma. Kuita uko kunogadzirwa pakati pemakemikari ari pasi pano kunokonzera kuti pH yeiyi ikwire zvishoma, ndokuti, inowedzera kuva alkaline.
Inoshandisa chii?
Calcium nitrate inoshandiswa ku:
- Rapa mvura yakasviba
- Kurumidza kumisikidza kongiri
- Uye sefetiraiza
Pane ino yekupedzisira poindi tiri kuzowedzera zvimwe:
Zvinhu zvekuziva usati washandisa calcium nitrate pazvirimwa
Tinotanga nemusoro wenyaya uyu, sezvo zvichizotenderera nekuti unonyanya kutibatsira here, kana kuti zvinopesana tinopera zvirimwa. Kuti, Chinhu chekutanga kuziva ndechekuti haIGONI kusanganiswa nefotereza ine sulfates uye / kana phosphorus., senge potasium sulphate kana phosphoric acid.
Uyewo, Kushandiswa zvisizvo kunogona kukonzera matambudziko kuzvirimwa. Anonyanya kuzivikanwa ndeye apical kuora kwemichero, lettuce nemucheto wemashizha "akatsva" kana tip kupisa, kana kuoneka kwemavara erima mavara pamaapuro anozivikanwa semakomba anovava.
Sechiyeuchidzo, Inofanira kutakurwa mundangariro kuti zvese calcium uye nitrogen zvakakosha pakukura kwakanaka kwemiti. Yekutanga inoshandiswa kuvaka maseru maseru, kugadzirisa kusagadzikana kurwisa kwezvipembenene nezvirwere, pamwe nemichero yemhando yepamusoro; nepo imwe yacho ichikosha kuti ivo vakure, sezvo iri zvakare chinhu cheklorophyll, girini pigment isina iyo yavaisazokwanisa photosynthesize.
Chii chingaitire zvirimwa?
Calcium nitrate inogona kubatsira zvakanyanya kumiti. Dzimwe dzadzo takatotaura, asi kuchine zvimwezve:
- Inonakidza ye simudza pH pasi
- Inobatsira kudzivirira (uye kururamisa, kana zvichibvira) kushomeka kwecalcium muzvirimwa
- Ita kuti vave nekukura kuri nani
- Inowedzera kushorwa kwechisikigo kwezvirimwa kurwisana nevavengi vako, senge mealybugs kana pathogenic fungi
Asi hongu, usamboishandisa kumiti yeacid, semaJapan maples, camellias, azaleas kana gardenias, pakati pevamwe. Iine alkalizing, yaizoita kuti mashizha ayo ave chlorotic, sezvo zvimwe zvakakosha zvinovaka muviri kwavari, senge iron, zvaisagona kutorwa nemidzi yayo.
Ndeipi muyero unozoshandiswa kumiti?
Calcium nitrate inowanikwa mugranular kana yemvura fomu. Madhiri acho anosiyana zvichienderana neizvi, asi kazhinji zvinotevera zvinokurudzirwa:
- Miti yemichero: 100-150kg / ha mushure mekugadzwa kwemichero.
- Herbaceous miriwo: 300kg / ha mumwaka wese.
- Horticultural vanokwira: 300-350kg / ha mumwaka wese.
Kana zvirimwa zvako zvishongo, muyero wacho unenge wakaderera zvakanyanya. Semuyenzaniso:
- Kana iwo ari muhari diki dzinosvika makumi maviri masendimita muhupamhi, iwe unofanirwa kuwedzera kapu kadiki (yeiyo yekofi).
- Kana ivo vari muhari hombe, chipunu.
- Kana ivo vari muvhu, anenge 50-100 gramu pamiti, zvichienderana nekuti idiki here kana kuti kwete.
Ivo vanofanirwa kugara vachibhadharwa vachitevera rairo dzemugadziri. Kana iyo dosi iri yakakwira kupfuura yakaratidzirwa, tichava nematambudziko muzvirimwa, uye kana iri yakaderera, hatingatomboona maitiro ayo.
Kwokutenga kupi?
Kana iwe uchida kutanga kuisa fetiraiza zvirimwa zvako ne calcium nitrate, saka usamirira zvakare uye wotenga kubva pano chaipo.
