Ulwelo Bardovskaya: iindlela nokulungiselela kunye nokusetyenziswa

Namhlanje, abalimi abanamava kunye egadini awuyazi esi sifo, ezifana phytophthora. Qho ngonyaka inani kwamagciwane liyenyuka, ngelo xesha kukho, iintlobo ezintsha olungaziwayo. Ngenxa yokuba ukusetyenziswa rhoqo kubo omnye uhlobo kweekhemikhali ayiyekeki ukuba ichiza, iminyaka ngeminyaka yonke, ekhemisi ceba izinto ezintsha kunye neefomula eziphuculweyo uluhlu olubanzi amanyathelo.

Abaninzi abamaziyo, kwaye isixhobo ezisetyenziswa ngokuqhelekileyo ke ulwelo Bard. Le nto iyakwazi ukutshabalalisa iintsholongwane nje kuphela, kodwa izinto. ukusetyenziswa kwezi esi sixhobo ifumene ukufuya iidiliya. Oku kusetyenziswa ikakhulu lokulawula izifo ezifana isibetho, anthracnose, ukubola abamnyama, yaye melanosis t. D.

Le into esebenzayo, osekwe Bard kulwelo iikhompawundi yobhedu. Bona ezinyibilikayo kancinane emanzini, nto leyo inegalelo nokhuseleko lwexesha elide kwezityalo.

Chemical umxube ukwakheka Bard na ezinye izinto awohluke. Le nto, njengoko umxube sulfate yobhedu lime. Bardovskaya ukulungiselela into engamanzi - inkqubo elula, iyindlela ephumelelayo nokulwa izifo zezityalo.

Ukuze ngokufanelekileyo ulungiselela ulwelo Bard, olinganise zilandelayo kufuneka ziqwalaselwe. Ngoko ke, ukuba singathatha sulfate yobhedu kunye lime xa om-2: 1, iikhompawundi ezahlukeneyo ifunyenwe iityuwa yobhedu. Xa umlinganiselo 1: 1, kunye CaSO4 wabumba CuSO4 ezimbaxa. Ngenxa yokunqongophala kwi kwekalika engamanzi bluestone kuhlala simahla, yaye ngenxa yoko, umxube sine-asidi medium. Ukusetyenziswa isisombululo esinjalo kukhokelela inkangeleko ukutsha imichiza izityalo.

Ngoko ke, lo umlinganiselo ngokupheleleyo sulfate yobhedu ikalika - ngu-4: 3. Xa inkqubo yamalungiselelo kufuneka ukuba basebenzise inqanawa 2 ezahlukeneyo ukuxutywa yeekhomponenti esibi. Umxhelo rhoqo, ngokucotha, umlambo obhityileyo wagalela isisombululo elungisiweyo ye sulphate ngobhedu lime. Ukuze ntlitha ulwelo modem kunye nentsimbi, ayikhuthazwa ukuzilungisa kwinkonkxa yentsimbi.

Emva kokufumana isisombululo yayo kusetyenziswa ngoko nangoko. Phambi kokuba enze njalo, qiniseka ukuba ubheke isisombululo ezizodwa uvavanyo Isalathisi reaction. Kufuneka ibe cala okanye ialakalin kancinane. Kungenjalo, kusenokwenzeka ukuba atshabalalise izityalo baphathwa kunye isisombululo asidi eziya kubangela ukutsha imichiza.

Eliphekwe ulwelo Bard, ukusetyenziswa esiza ukulwa izifo zezityalo, kananjalo kuneengxaki zako. ukusetyenziswa rhoqo zesixhobo kunganqanda isityalo. Ngoko ke, umzekelo, yakuba yidiliya ukuhla kwesantya sokukhula kumagqabi. Imveliso ye kwimeko enjalo ke ukusetyenziswa organic njengezibulali. ukwakhiwa kwawo asibandakanyi ubukho zezobhedu.

Oku lulandelayo ezijongene ulwelo Bard sisixhobo buyafuneka ukwenzela unyango izityalo. Inkqubo ukupheka lulula kakhulu kwaye ayiyi kuthabatha ixesha elininzi. Iindleko esiphantsi sexabiso ulwelo uyixhome kwenye yeendawo zokuqala ekulweni izifo zezityalo.
