Iyo yakawanda yakawanda acidity yevhu inodzvinyirira mbeu uye inoputsa zvirimwa zvavo. Kune boka duku rezvirimwa zvinokura zvakasimba pane ivhu rakaoma kwazvo, semuenzaniso cranberries. Asi kunyanya munda wekurima unoda midzi uye isina simba asi ine ivhu. Mukuwedzera, ivhu remasidhari rakaomeswa zvakashata, uye rinomuka, rakafukidzwa nehombodo yakaoma. Kuti irege kugadzirisa asidi iri mune ivhu, kudonha kwevhu kunoitwa. Pamusoro pezvo, kupera kwevhu rakaoma kunowedzera kuve kwekurima kwezvirimwa zvesango, nekuda kwekukura kwesimbi yakanyanya midzi inobudirira munyika isingaiti.
Calcareous substances
Zvigadzirwa zvemarimu emasikirwo emhuka (makeminone, dolomites, marl) uye lime rine teknolojia (waste shale ash, sement guru, white sludge) zvinoshandiswa. Zvose izvi zvinenge zvakagadzirwa kana chaki kana calcium carbonate zvakasiyana. Asi chii chiri nani kuisa muvhu? Varimi vemizambiringa vane makore akawanda vane ruzivo vanorayirwa kuti vashandise zvakagadzirwa nemaitiro emakemikari, iyo 10 zvikamu zve calcium inokwana 4 kusvika ku 8 chikamu che magnesium. Kutanga kwedambudziko rine zvinhu zviviri zvinokurudzira kuwedzera kwezvibereko zvezvirimwa zvakawanda kusvika pane zvakanyanya kushandiswa kwema calcareous fertilizer pasina magnesium.
Kakawanda kwemigomo
Agrotechnics inokurudzirwa kuti iite marimu evhu pane dacha kamwe chete pamakore matanhatu kusvika kune makumi matanhatu, nokuti semugumisiro wezviitiko zvinowanikwa muvhu, kushandiswa kwemamiriro ezvinhu zvishoma nezvishoma kunoshanduka, kudzokera makore akawanda kusvika pachiyero chepakutanga.
Nzira yekuziva sei kuti ivhu rinoda kudii?
Iyo ivhu rakasvibiswa neyimu, iri kutungamirirwa nezviratidzo zvekunze zvepasi. Chokutanga pane zvose, ivhu rakaoma kwazvo nevhu rakachena kana grey-white hue uye podzolic horizon nehupamhi hunopfuura 10 cm dzinodiwa mukudzivirira.Zvinokosha zvekugadzirisa zvinotaridzirwa zvose nehurumende yemiti yakadyarwa uye nekukura kwemasora. Kunyanya kunzwisisika kune acidity kunowanikwa mugorosi, clover uye beet, kukura kwavo kusimba kunoratidza kuti kunonoka kwenyika kunodiwa. Mamwe masora anokura zvakanaka pamusoro penheyo dzevhu. Kukura kweheather, Ledum, zvinokambaira buttercup, pike, sorrel zvinoratidzawo kuwanda kwevhu ivhuidi. Pakutengesa kune mapepa-mapepa anobatsira kuti zvinakwanise kuzarura zviri mukati measiti muvhu.
Ndirini pandinofanira kugadzira lime?
Pakutanga, rinesi inoshandiswa painoisa bindu panguva yekugadzirira nzvimbo. Zvadaro kushandiswa kwekushandisa makestone fertilizer inoitwa mukati megore (kubvumbi) nyika isati yasvika.
Mutengo unoshandiswa nemarara kune ivhu
Nhamba dzekushandiswa kwe hydrated lime yevhu dzinobva pa:
- acidity yenyika;
- composition yevhu;
- zvinyorwa zvemakemikari manyowa anoshandiswa;
- kudzika kwekupinza.
Izvo zvakanyanya acidity, lime inorowa muvhu mune doses guru. Iine asidi yakasimba, 0.5 kg yemakestone pa 1 m2 inoshandiswa muvhu nevhu rakaoma, 0.3 kg nevhu jecha. Paavhareji acidity - pamwe chete 0.3 kg uye 0.2 kg. Pamusana asidi isina simba - ivhu uye loamy 0,2 kg inotangwa, denga rejecha harisi iro limy.
Nzira yekuita seike muvhu?
Kazhinji varimi havazivi kuti vangasvibisa sei ivhu. Chine chakanga chisingatarisirwi chakasvibiswa chakaiswa mupfu uye chakasvibiswa nemvura kuti chidzimise. Slaked powdered lime pakarepo yakasanganiswa nenyika. Kushungurudzwa kweiyo nevhu kune chinhu chakakosha kuti zvive zvakanaka.
Chiito pane ivhu rinopera minye
Nyikaworms haina kubereka zvakanaka muvhu dzomusidhari, saka kurapa ivhu nehute muhuwandu hwakaratidzwa, kunobatsira kune vanhu vezvisikwa izvi zvinobatsira.
