I. "Grey Zone" yeOrganic Standards

Kuvhura "Mitemo Yekuitwa kweOrganic Product Certification," Chisungo chechinomwe cheChitsauko 2 chinoburitsa zvakajeka marudzi makumi mashanu nepfumbamwe emishonga yezvipembenene yemiti nemamineral inotenderwa kushandiswa. Biopesticides senge azadirachtin uye pyrethrins inosanganisirwa zvakanyanya. Kunyangwe izvi zvinhu zvakatorwa kubva muzvirimwa zvechisikigo zvinotsanangurwa se "low toxicity," kupfapfaidza zvakanyanya kunogona kutungamirira kune zvakasara. Chinonyanya kunetsa ndechekuti zviyero zvechitupa zvinoisa nguva yekucheneswa kwevhu kwemwedzi makumi matatu nematanhatu, asi glyphosate metabolites kubva kuminda yapfuura yekurima inogona kuramba ichionekwa mumvura yepasi kune mamwe mabhesi muNorth China Plain.

Nyaya dzechlorpyrifoszvakasara mumishumo yekuedza zvinoshanda seyambiro. Chimwe chigadziko chakasimbiswa, chiri padyo neminda yechinyakare, yakatambura nekusvibiswa kwemishonga yezvipembenene mumwaka wemonsoon, zvichikonzera kuonekwa kwe0.02 mg/kg yezvakasara zve organophosphorus mumasampuli espinachi. Uku "kusvibisa kusvibiswa" kunofumura kusakwana kweiyo iripo certification system mukutarisa zvine simba nharaunda yekurima, kubvarura mutswe mukuchena kwekurima organic.

II. Chokwadi Chakafumurwa Mumarabhoritari

Paunenge uchishandisa gasi chromatography-mass spectrometry, matekinoroji anoisa muganho wekuona wemasampuli pachiyero che 0.001 mg/kg. Data inoratidza kuti 90% yemasamples akanaka aive neakasara mwero chete 1/50 kusvika 1/100 yeavo vari mumiriwo yakajairika, zvakaenzana nekudonhedza madonhwe maviri einki mudziva rekushambira. Nekudaro, kufambira mberi mune tekinoroji yemazuva ano yekuona yakagonesa kutorwa kwemamorekuru padanho-mu-bhiriyoni, zvichiita kuti "zero yasara" rive basa risingaite.

Kuoma kwemaketani ekusvibisa-kukanganisa hakugone kufungidzira. Kusvibiswa kwemuwarehouse nekuda kwemotokari dzekutakura dzisina kucheneswa zvakakwana kunotora 42% yemitengo yezviitiko, ukuwo kusvibiswa kwekubata kunokonzerwa nekuiswa kwakasanganiswa pamasherufu esupermarket inoita makumi matatu nerimwe%. Nehunyengeri, mishonga inorwisa mabhakitiriya yakasanganiswa mune imwe organic fetiraiza mbishi inopedzisira yapinda mumasero emiriwo kuburikidza ne bioaccumulation.

III. Nzira Yepfungwa Yekuvakazve Kuvimba

Vakatarisana nemushumo wekuyedza, murimi wekurima airatidza "sparent traceability system" yavo: QR kodhi pasuru yega yega inobvumira kubvunza reshiyo yemusanganiswa weBordeaux wakaiswa uye mishumo yekuongorora ivhu yemakiromita matatu akatenderedza. Iyi nzira yekuisa maitiro ekugadzira pachena iri kuvakazve chivimbo chevatengi.

Nyanzvi dzekuchengetedza chikafu dzinokurudzira kutora "nzira yekuchenesa katatu": kunyura mumvura yekubheka soda kuti iparadze mishonga inonyungudika nemafuta, uchishandisa ultrasonic cleaner kubvisa pamusoro adsorbates, uye blanching kwemasekonzi mashanu pa100 ° C kuti inactivate biological enzymes. Idzi nzira dzinogona kubvisa 97.6% yezvisaririra zvekutsvaga, zvichiita kuti mutsara wekudzivirira hutano uwedzere kusimba.

Data yekuongorora marabhoritari haifanire kushanda semutongo unoramba kukosha kwekurima kwekurima. Kana tichienzanisa 0.008 mg/kg ye chlorpyrifos yakasara ne 1.2 mg/kg yakaonekwa mune yakajairwa celery, isu tinogona kuona kushanda kwakakosha kwemaitiro ekugadzira organic mukuderedza kushandiswa kwemishonga yezvipembenene. Zvichida kuchena kwechokwadi hakuziro zvachose, asi mukuenderera mberi kusvika zero, izvo zvinoda kuti vagadziri, vagadzirisi, uye vatengi varuke pamwe chete network yakasimba yemhando.
