Munenge mumichero yose gindu rinokura miti yemapuro, iyo inowanzosangana nechirwere. Iyo haibatsiri hupenyu hwemuti pachayo, asi inongopedza zvishoma zvezvibereko uye inowedzera kunaka kwechibereko.
Ko ganda riri pamapuro rinoratidzika sei?
Pakuguma kwemaruva munaMay pamashizha anooneka ari rima, zvishoma nezvishoma inokura mavara nemucheka wakachena. Matambudziko anokanganisa anofa, uye pakati pezhizha kune kurasikirwa kwemashizha kubva pamuti. Izvi zvinokanganisa zvakaipa kwete chete kukohwa kwegore razvino, asiwo kuumbwa kwemichero buds.
Kukundwa kwechibereko kunotanga nekuumbwa kweivary. Idzo dzakapoteredza kana dzisina matanda, dzakaputirwa nemuorivhi. Pakutanga kwekona kaduku, saka vanova vakuru zvikuru. Pamichero iri pasi pemaruva kune cork layer inogadzirwa, iyo inodzivirira fungus kuti ipinde mukati memucheche. Akabatwa zvibereko zvakanyanya kuwira, uye zvakasara kuva imwe-sided. Kana hutachiona hukaitika munguva pfupi, panguva yekukohwa, zviratidzo zvehutachiona hwemuapuro-muti, chikafu hachioneki, asi chinoonekwa panguva yekuchengetedza: maduku madota anoonekwa pazvibereko, izvi zvinotungamirira kuderedza kuderedzwa kwezvibereko. Panguva imwe chete, maapuro ane utano haatapukirwi.
Pamapfudzi, kukundwa kweganda kunoratidzwa nekuonekwa kwekodhikisi yezviduku zviduku, izvo zvino zvakabvamburwa, zvichiita kuti cortex isakanganwe, ichitsemuka, uye zvinoputika zvakanyanya zvinomera.
Kunyanya intensively chirwere chinokura mumvura, t. Spores of the causative agent of this disease germinate in a liquid medium. Vanotakurwa nemhepo, zvipembenene nemvura. Iyo mishonga inogona kurarama pamashizha akadonha, michero yehutano uye mune bark remapfudzi anoputika.
Nzira dzokurwisana neganda pamapula miti
Nzira dzokurwisa chirwere ichi chinosanganisa dzinosanganisira:
- kurapwa kwemafuro paaple;
- nzira dzokudzivirira maapuro kubva pachigamba.
Nzira yekurasira maapuro kubva pachigamba?
Muchirapa chekuda kwekurapa miti yemapuro, kupomera nemishonga yakasiyana-siyana uye majisi kunogona kushandiswa, kusarudzwa kwaro
- kunobva panguva uye nzvimbo yekushandiswa kwavo:
- kunyura-midzi 10% yerammonium nitrate ;
- panguva yeBhu blossoming 3.0% Bordeaux fluid (kana yakanyanya kupisa, zvino shandisa 1% solution);
- apo buds inowoneka - 1.0% Bordeaux mvura, mhangura yekorodi, Kuprosilom, Rubigan, Strobi;
- pakarepo mushure memvura - fungicides Skor, Rubigan, Horus, Sistan, Ditan;
- mushure mokukohwa: muti wacho pachawo - 4-5% urea solution, uye mashizha akawa uye ivhu pasi pemuti 7% urea solution.
Matanho okudzivirira kuchengetedza aporo kubva pachiganda:
- kuparadzwa kwezvinhu zvehutachiona (mashizha, michero);
- kusika kwemamiriro asina kunaka ekuvandudzirwa kwechirwere (kwete-kuterera, kuchenesa zvakanaka uye zuva rinopenya korona yemiti);
- kurima kwemitsara pakati pemigwagwa, nekuchera mumatanda nemashizha akafa akaiswa mukati.
- nekuda kwekusabvumira utachiona hwekutanga hwehutachiona hwakawandisa munguva yegore nguva isati yatanga kuzarura, kurapwa ne 1% sarudzo yeDNOC kana korona yegirini ine 3% solution yeBordeaux fluid;
- Tincture yegoriki (200-300 g yekiki yakakoswa, inya 2 litita emvura inopisa, tsanidza maawa makumi maviri nemasere uye kuoma, kunya ne 8 litita emvura inotonhora uye uwedzere 30 g ye sese yekuchenesa).
Chinonyanya kukosha pakurwisana nechepamusoro pamapurisa ane chisarudzo chekudyara mbeu dzakasimba. Izvi zvinosanganisira Perlina weKiyi, Amulet, Oder, Tsyganochka, Reina, Sava, Rusununguko, Odra, Rubinola, Topaz, Revena, Prima, Priscilla, Florina, Liberty, Syrpray.
Kana iwe uchida kuwana kukohwa kwemaapuro anonaka uye akanaka kubva mubindu rako, saka nenzira yakakodzera panguva ino chengetedza kuchengetedza miti yako yeapuro kubva pachiganda.
