Kudzidzira kwakaratidza kuti mhedzisiro yehumic acid pakudzoreredza ivhu nekuvandudzwa kuri pachena. Kunyanya kuratidzwa muzvikamu zvitatu:
1. Humic acid inoshandura chimiro chesimbi inorema muvhu rakasvibiswa
Kuunganidzwa nekupfumiswa kwesimbi dzinorema kunounza dzvinyiriro huru kuvhu. Mazhinji emafomu aripo muvhu ane chelated kana akaomarara. Humic acid yakapfuma muhuwandu hwakawanda hweiyoni. Inogona kutsiva chelated state nemaion ayo. Neheavy metal ions munzvimbo yakaoma, simbi inorema haibatike nyore nezvirimwa, uye zvirimwa hazvisvibiswe nyore nesimbi inorema. Chiedza humic acid (fulvic acid) ine huremu hwakaderera hwema molecular, iyo inobatsira ku activation, kugarisana uye kupera kwesimbi inorema. Heavy humic acid (inosanganisira palm humic acid neblack humic acid) ine huremu hwakati kurei uye ine mhedzisiro yekudzikisa uye kushambadza nekugadzirisa simbi dzinorema, izvo zvinogona kuderedza kushanda kwesimbi inorema, sekugadzirisa cadmium, mercury, uye lead. .
2. Humic acid inoderedza huturu hwevhu muvhu rakasvibiswa
Mumwe “muparadzi” wevhu ivhu rinosvibisa. Zvitubu zvinonyanya kuita petroleum uye pyrolysis zvigadzirwa, mishonga yezvipembenene, organic synthetic zvigadzirwa (senge plastiki mulch, nezvimwewo); humic acid inogona kugadziriswa muvhu nekuwedzera adsorption uye kugadzikana kwe organic matter Nenzira iyi, izvo zvinosvibisa zvinorasikirwa nebasa razvo, kana kuti zvinokonzeresa fotolysis uye kuparara kwemakemikari eiyo inoshanda mahara radicals ye organic matter, kuitira kuti iwane mhedzisiro. ye "detoxification" yevhu. Iyo humic acid "inoora mulch" inogadzirwa neheavy humic acid seyakabikwa inoderedzwa kuita humic acid organic fetireza mwedzi miviri kusvika mitatu mushure mekushandiswa. Zvirimwa zvinomera zvega, zvichichengetedza vashandi nenguva, uye kudzivirira "kusvibiswa kuchena" kunokonzerwa nepurasitiki mulching. .
3. Humic acid inogona kushandiswa pakurapa kwesaline-alkali ivhu rine mvura yepasi isingasviki 1 mita.
Humic acid inogona kusanganiswa nekarusiyamu uye iron ions yemamwe adjuvants kusimudzira kuumbwa kwemahombe-particle aggregates muvhu rakatsetseka re20-30 cm pamusoro, kuderedza capillary phenomenon yevhu rakatsetseka, uye zvakanyanya. kuderedza kubuda kwemvura kutakura munyu pamusoro uye zvishoma nezvishoma Kuunganidzwa kwemunyu ndiyo nzira inoshanda yekudzora zvachose saline-alkali ivhu kubva patsime.
