Kumwa kwemushonga wesora kunotaridza kuti yakawanda sei kemikari yakaiswa inowanikwa kuzvirimwa uye inosvika panzvimbo yainoda kuita. Mamiriro evhu anokanganisa zvakanyanya kuwanikwa uku mushure mekushandiswa muminda yekurima.
Kana mishonga yesora ichinge yapinda muvhu, inogona kutorwa nevhu nevhu, inogona kuramba yanyungudutswa mumvura yevhu, kana kufamba nepakati pevhu nemvura nemhepo.
Kuenzana pakati pemaitiro aya kunokanganisa kurwisa sora, kuchengetedzwa kwembesa, kusamira kwemishonga yesora, uye mukana wekusvibiswa. Naizvozvo, kunzwisisa zvinhu izvi kunotsigira zvirinani sarudzo dzekushandisa mushonga wesora paivhu rekurima rakasiyana.
Zvizhinji zvevhu nemishonga yesora zvinopindirana panguva iyi. Clay type, organic matter, ivhu pH, mwando, chimiro chemakemikari, leaching, diffusion, uye kuyerera kwehuwandu zvese zvinopesvedzera kuwanikwa kwesora.
Chinyorwa chino chinotsanangura kuti zvinhu izvi zvinodzora sei kubatwa kwesora uye kufamba muvhu. Zvinoratidzawo kuti sei mushonga wesora mumwechete uchigona kuita zvakasiyana pasi pevhu rakasiyana uye nemamiriro ekunze.
Clay Colloids uye Herbicide Absorption
1. Clay Surface Area: Ivhu remhando yevhu rinokanganisa zvakanyanya adsorption nekuti zvimedu zvevhu zvinopa nzvimbo yakakura uye machaji emagetsi anochengeta mamorekuru emushonga wesora, zvichisiya makemikari mashoma anyungudika mumushonga wevhu.
2. Montmorillonite: Montmorillonite ine lattice iri kuwedzera uye inopa ekunze uye emukati maficha ekushambadza. Chimiro chayo chinopa yakakura adsorptive kugona pane illite, nepo kaolinite kazhinji inopa isina kusimba adsorption.
3. Illite And Kaolinite: Illite ine matatu akaturikidzana asina montmorillonite ari kuwedzera hunhu. Kaolinite ine maalternating layers uye mashoma asara machaji, kunyangwe nzvimbo yayo yehydroxyl inogona kuchengetedza mamwe organic makemikari zvakasimba.

Ivhu Organic Matter uye Herbicide Binding
Organic matter inomiririra chimwe chezvinhu zvakakosha zvinokanganisa kushambadza kwesora muvhu. Inosanganisira humic zvinhu, zvisaririra zvezvirimwa, zvisaririra zvemhuka, uye tupukanana tunopa mamwe anosunga nzvimbo.
Humic acid, fulvic acid, uye humin zvinoumba zvikamu zvikuru zvehumic. Zvishandiso izvi zvinopesvedzera kuti mishonga yesora inosunga sei, ukuwo zvisaririra zvinoora zvichikwanisa kusimudzira sorptive yakawanda sezvo cellulose inodzikira.
Yakasimba organic matter adsorption inogona kuderedza kunyura kwesora mumhinduro yevhu uye kuderedza kutorwa kwechirimwa ipapo. Nekudaro, gare gare desorption inogona kudzorera chikamu chekemikari yakachengetwa mumhinduro zvakare.
Ivhu pH Uye Kunyura kweHerbicide
1. Ionization yemishonga yesora: Ivhu pH rinoshandura kuchaja kwemushonga wesora uye rinoshandura kudyidzana nevhu rinochajiswa zvisina kunaka uye organic zvinhu. Inogona zvakare kukanganisa cation exchange kugona uye microbial maitiro anokanganisa maitiro.
2. Mishonga yeAcidic uye Basic Herbicides: Mishonga inouraya sora yakaita se2,4-D, MCPA, dicamba, uye picloram inogona kuburitsa maion ehydrogen mumhinduro dzisina kwazvakarerekera. Mishonga yesora inokwanisa kugamuchira maion ehydrogen pasi pemamiriro ane acidic.
3. Mishonga yesora yakasimba: Mishonga yesora yakasimba yakadai separaquat uye diquat inogona kuramba yakachajiswa paivhu rakajairwa pH mamiriro. Naizvozvo vanosunga nekukurumidza uye zvakasimba kune ivhu uye organic matter.
Hunyoro hwevhu uye Kuwanikwa kwemishonga yesora
Kunyorova kwevhu kunokanganisa adsorption, desorption, diffusion, uye phytotoxicity yemishonga yesora iripo mumhinduro yevhu. Mamorekuru emvura anokwikwidzana neorganic compounds kune anowanikwa adsorption nzvimbo mukati meivhu zvidimbu.
Mumamiriro ezvinhu akaoma, mashoma mamorekuru emvura anokwikwidza kunzvimbo dzeadsorption, achibvumira mamwe mishonga yesora kuti ichengetwe zvakanyanya. Kuwedzera kunyorova kunogona kuendesa mamorekuru aimbove adsorbed kuita ivhu mhinduro.
Mvura yakawanda inosimudzirawo kupararira kwema molecular uye kuyerera kwehuwandu kuburikidza nevhu. Nekuda kweizvozvo, hunyoro hunogona kuwedzera kuwanikwa kwemishonga yesora pakutora chirimwa uku panguva imwe chete ichiwedzera kufamba kupfuura kwainotarirwa.
Chemical Properties uye Herbicide Absorption
