Pakupera kwezhizha, vagari vemazhizha vanokohwa kukohwa, verengera nguva yacho ichiguma, uye vanoisa pasi mamiriro ezvinhu ekuti nguva yekukohwa inotevera iite seyakapfuura, uye zviri nani. Uye zvipenyu zvose zvinowedzera panzvimbo iyi, zvichiri kuda kutarisirwa nekuchengetedzwa kwakakodzera, nokuti kanopfuura kamwechete vachazofadzwa newe nekudzoka nenzira yezvibereko zvinonhuhwirira uye mishonga itsva.
Havasi vose vemizambiringa vanoita zvirongwa nevhu rakaorera rakaorera. Kana iyo nzvimbo isiri kure nemusango, bhiza rerusrel, fern uye masango akasiyana-siyana emasango anowedzera zvakakwana pazviri, zvino zvinogona kugumiswa kuti ivhu pano rinoratidzwa nehupamhi hwehushi. Pasina kutora matanho akakodzera kuti ufukidze ivhu, iwe unomhanyira mungozi yekurasikirwa nezvirimwa zvawaive uchiverenga. Strawberries, tomato, kabichi uye makomkoro kune ivhu nehupamhi hwe acidity hairi kukura sezvaunoda.
Nzira yekugadzirisa sei asidi yevhu?
Kuti usvibise ivhu riri panzvimbo, iwe unoda kuziva kuti, chii, uye nguva yekuita. Ichokwadi, iyo acidity inowedzera yehuhydrogen ions muvhu. Ichi chemakemikari inogadzikana haibvumiri mbeu kuti dzigadzirire zvizere. Nezinga rakakwirira reasidity, midzi inogona kunyange kufa. Mukuwedzera, zvose zvinoedza kuvandudza mamiriro acho nemafuta zvinokonzera kukundikana, nokuti nekuda kwehydrogen ions, chero humwe huwandu hwemumanyorera hunoshanduka kuva maminera asina kukodzera kugadziriswa nemiti. Chikamu chikuru chezvirimwa zvinowanzobudirira kune ivhu, pH inoshandiswa iyo iri muhuwandu hwe5,5-6.5 (isina simba asiri uye isina kusimba). Zviratidzo zvakadaro zvinowanzoenderana nemhepo ine mvura yakawanda yakakwana. Mune ivhu rakaoma kune zvakawanda zvema manganese uye aluminium, izvo zvinodzvinyirira mbeu. Munawo wose, ne acidity pasi pe5 pH, iwe unofanirwa kufungisisa nezvekuderedza ivhu mukuwa. Izvi zvakakosha kuitira kuti kuwedzere kubuda kwe calcium, molybdenum, phosphorus uye magnesium, uye kubvisa kukanganisa kwema manganese, iron uye aluminium. Mukuwedzera, deoxidation inokurudzira kuchengetedzwa kwe nitrogen muvhu.
Kazhinji kazhinji, ivhu rakasvibiswa rinogadzirwa nemarara, iyo inonzi "pushenka". Kana lime risati rapera, ipapo alkali ichaunganidzwa muvhu, uye kupisa kwakabudiswa munguva yekuita kunogona kutungamirira kumidzi inopisa. Norm yearimi yakasarudzwa kune imwe nzvimbo yevhu. Uyezve, ivhu rinokonzerwa nehupfu ye dolomite, sement yekare, chiko kana pome yakaoma. Muchiitiko ichi, deoxidizing zvinhu zvinoda 30% mamwe. Apo deoxidizing ivhu negoroko, gypsum kana alabaster, tora kaviri deoxidizer. Cherechedza kuti kumunhu zvimwe zvezvinhu izvi hazvibatsiri, uye, somuenzaniso, deoxidizing ivhu nemafuta emarara inoda 10 dzimwe nguva slag!
Kana nzvimbo yacho iri duku, unogona kuderedza asidi yevhu nekubatsirwa kweii shell. Kuti uite izvi, zvisinganzwisisiki zvakabikwa muzinga rinopisa, pasi pasi zvishoma uye kudyara musina mutsara pamibhedha.
Mune mamwe mabhuku munhu anogona kuwana ruzivo rwekuti dzimwe vagari vemazhizha vanoita ivhu rekunyangadza, asi akawanda agrotechnists anofunga kuti nzira iyi haina kunaka. Ichokwadi ndechokuti sodium inowanikwa mairi inokwanisa kuunganidza, uye kudarika kwayo kunogona kukuvadza iyo michero kunyange kudarika ivhu reyasi.
Miti-vatsigiri
Mukuwedzera kune zvinhu zvakanyorwa pamusoro, panewo
Ndezvipi zvimwe zvinomera zvinoderedza ivhu? Iyi birch, alder, spruce, elm, hornbeam uye pine inogona kuderedza asidi yevhu kune imwe hafu yemamita yakadzika.
