Your kudiridza nzira iri "kuuraya" ivhu

Nokuti vanhu vakawanda, ivhu salinization zvose vanoshamwaridzana uye ausingazivi. Familiar nayo, nzvimbo zhinji dzakadai China kumahombekombe nzvimbo uye kure negungwa nzvimbo vane munzvimbo huru munyika sesaline-alkali kuti kunogona kuonekwawo kwose kwose. Paumbwe munyika sesaline-alkali kwakadaro wakabatana omunzvimbo okunze, ivhu, kwakaita nzvimbo yacho, geomorphology, zvemaumbirwo uye zvimwewo. Alkalinization. Vambonzwa ndechokuti ivhu salinization ari kurima anokonzerwa musoro matanho evanhu haasi tsime kunzwisisa.
Musoro matanho evanhu kunyanya nokuda mururamisi kudiridza uye abudise gadziriro, kunyanya kudiridza, murombo abudise, zvichiita pasi pamwero kumuka, zvichiguma ivhu salinization, unonzi ivhu salinization yechipiri. Sesaline-alkali nyika iri kuwedzera ose gore, nokuda "mupiro" yevanhu. Kune vakawanda yechipiri salinization nzvimbo, uye vanenge mamiriyoni 10 hectares nyika vachadzingwa pagore nokuda yechipiri salinization ivhu.
Maererano nokutsvakurudza, nzizi maviri mumwe mikuru dzomunyika zvina zvenyika, chikuru chikonzero kutsakatika ndiyo salinization yechipiri ivhu.

Musoro kudiridza kutungamirira sei kuti ivhu salinization?
Soil salinization, zviri nyore, ndiko kuti vaunganidza munyu pamusoro pemvura ivhu akapfuudza achishivirira kuti chirimwa uye kunokanganisa dzose ikure chirimwa.

Flood irrigation

 Ingava chikuru kana yechipiri, vakawanda munyu vaunganidza pamusoro pemvura ivhu kunobva pasi, uye pasi achisimuka pemvura pedyo pemvura kubudikidza rirambe richibvira chiito, kuunza yomunyu pechiso ivhu.
Kiyi iyi "pasi akamuka." Kana yakawanda kudiridzwa iri guru, mvura achava pinda pasi zvikuru, kuti abudise achava murombo, iri pasi pamwero wenyika kurimwa munyika vachamuka, ari pasi achawana pedyo pasi, uye munyu vakatakura iri mvura ruchasveerera pamusoro nyore.
In iyi, zvakakosha kuti ataure simba kubatsira kuunganidza munyu pamusoro pemvura - kwemvura simba.
Kana pasi kunounza ivhu salinity pemvura, simba kwemvura achakurumidza kudzorera mvura mvura mhute, asingakwanisi kuramba kutakura munyu, uye munyu tichagara pasi ivhu pamusoro. Pashure vachikwira-kuunganidza zvinogara, pemvura ivhu rinoungana munyu, uye kwenguva yakareba, ivhu zvichabviswa salinized.
The salinization yechipiri evhu kunyanya rikaitika dzisinganayi uye Semi-dzisinganayi dzinodiwa simba kwemvura, uye kwemvura mukuru kunonaya. Zvinonzi kusiyaniswa kubva chizvarwa salinization ivhu, kunyanya zvichikonzerwa evanhu zvoupfumi basa.

Secondary salinization of soil

 Soil salinization kurapwa nzira

Soil salinization kurapwa kwagara chinetso chikuru nezvakaonekwa ivhu nemasayendisiti. Ingava chikuru salinization kana yechipiri salinization, akaenzaniswa akafanana. Nzira inokosha Hurumende iri kuti abvise pasi vosimba-munyu kumusoro-kwemvura kuwanda kwacho.
Kuvandudza zvekurima abudise hurongwa
anonyanya kubva kudiridza, abudise, siltation, Anti seepage nezvimwe anokosha utariri. The yakachena mvura (mvura kana mafashamo kudiridza) chinoshandiswa kurigeza ivhu, uye abudise gadziriro discharges zvakawandisa hwevhu kubva ivhu nenguva. Mvura yakachena rinosuka kubvisa ivhu uye tora zvakawanda munyu. Chechipiri, kuti pasi pamwero zvinogona kudzorwa kuti ngozi kudzika, kuderera ivhu kwemvura uye kuderedza munyu kufamba kumusoro.
Soil firimu
Kuburikidza ivhu unhani, zvinogona kutadzisa pemvura ivhu kuuya neZvapupu muchadenga, kuderedza kwemvura uye kuderedza pasi kuwedzera.
Soil changed nzira
chairo kushandura ivhu pamusoro sesaline-alkali penyika kuti yepamusoro ivhu. Kudyara munyu-kushivirira zvirimwa zvakare chakajairika kurapwa.
Nokuti salinization yechipiri, chinonyanya kukosha ndechokuti kuvandudza kudiridza uye abudise zvivako kudzivisa kunyanya kudiridza panguva kudiridzwa; pashure kudiridzwa, zvakawandisa mvura inogona asunungurwa nenguva. Rokurima abudise hurongwa pari yainyanya kushandiswa uye inoshanda mhinduro. It vangasimudzira paanoparadza cyclical gadziriro pasi vosimba-munyu kumusoro-kwemvura uye munyu kuwanda. Vamwe dzinoshandiswa kuvandudzwa pasi yaivapo ezvinhu.
