Bardovskaya ketshezi: izindlela ukulungiswa nokusetshenziswa

Namuhla, bambalwa ngabalimi asebenolwazi futhi balimi ungamazi lo nezifo ezinjengesifo Phytophthora. Minyaka yonke inani Amagciwane liyakhula, ngesikhathi esifanayo kukhona amasha, amafomu bonobumba. Ngenxa yokuthi ukusetshenziswa njalo wabo ngokumelene eyodwa uhlobo amakhemikhali umlutha emuthini, minyaka yonke, osokhemisi baziqambela izinto ezintsha kanye amafomula okuthuthukisiwe ezahlukene ebanzi of action.

Ngiphephile owaziwa futhi evame ukusetshenziswa ithuluzi awuketshezi Bard. Lokhu kwaziswa kuyinto enamandla okubhubhisa nje amagciwane kuphela kodwa futhi isikhunta. Ukusetshenziswa kabanzi leli thuluzi lithole e ezifanelekayo ukufuya amagilebhisi. It isetshenziswa ngokuyinhloko for ukulawula izifo ezifana isikhutha, anthracnose, abamnyama bola, futhi melanosis t. D.

Ingqikithi asebenzayo, okuyindawo ehlanganisa a Bard liquid compounds zethusi. Ziyakwazi kancane oncibilikayo emanzini, okuyinto enomthelela Ukuvikelwa eside izitshalo.

Chemical Ukwakheka Bard ingxube has ezinye izici. Lokhu akulutho, njengoba inhlanganisela zethusi sulfate nomcako. Bardovskaya ukulungiselela liquid okuyinto - inqubo elula, iyindlela ephumelelayo ukulwa nezifo isitshalo.

Ukuze silungiselele kahle ketshezi Bard, kumele olinganise ezilandelayo uyalandelwa. Ngakho, uma sizinika sulfate zethusi futhi lime ngo isilinganiso 2: 1, compounds ahlukahlukene etholwe nosawoti zethusi. Lapho isilinganiso 1: 1, futhi CaSO4 kwakhiwa CuSO4 kwakwakhe. Nge ukushoda ketshezi lime bluestone uhlala free, futhi ngenxa yalokho, ingxube ine naphakathi acid. Ukusetshenziswa isixazululo okunjalo ngeke kuholele ukubukeka ukusha chemical ezitshalweni.

Ngakho-ke, i-ratio elilungile zethusi sulfate nomcako - 4: 3. Ngo inqubo ukulungiselela udinga ukusebenzisa 2 isitsha ehlukile dilution yezingxenye ingxube. Ukuvusa njalo, kancane, ukusakaza mncane wathela isixazululo ukulungele zethusi sulphate e lime. Ukuze Bard ketshezi akasabeli ne metal, is hhayi Kunconywa ukuba ulungiselele it in an isitsha yensimbi.

Ngemva kokuthola isisombululo yalo isetshenziswa ngokushesha. Ngaphambi kokwenza kanjalo, qiniseka ukuthi uhlole isivivinyo inkomba yokusabela isixazululo ekhethekile. Kufanele kube noma hlangothi noma kancane ane-alikhali. Uma kungenjalo, kungenzeka ukubhubhisa izitshalo ziphathwe isixazululo acid eziyobenza ukusha zamakhemikhali.

Bard eliphekiwe ketshezi, ukusetshenziswa esiza ukulwa nezifo zezitshalo, Ubuye nezihibe. ukusetshenziswa evamile ithuluzi singavimbela isitshalo. Ngakho, ngokwesibonelo, amagilebhisi ukwehla nezinga lokukhula of amahlumela. Okukhiphayo esimweni esinjalo ukusetshenziswa nesikhunta organic. Ukwakheka yabo akufaki khona wethusi.

Ngakho kusukela osekushiwo ukuthi uketshezi Bard iyithuluzi elibalulekile for ekwelapheni izitshalo. Inqubo ukupheka silula futhi ngeke kuthathe isikhathi esiningi. Izindleko iphansana ketshezi ubonisa ke kwenye yezindawo zokuqala ekulweni nezifo zezitshalo.
