Mukurimwa kwegirinhi hanyanisi, garlic, leeks, anyanisi uye mamwe anyanisi uye garlic miriwo, chiitiko chekuoma tip chiri nyore kuitika. Kana kutonga kusina kunyatsogadziriswa, nhamba huru yemashizha emiti yose ichaoma. Mumamiriro ezvinhu akaoma, munda uchava semoto. Hune simba guru pagoho, uye mumatambudziko makuru, hahukwanisi kukonzera goho. Chii chinokonzera izvi uye nzira yekudzivirira nayo? Nhasi, ndinoda kukurudzira yakanakisa fungicide kumunhu wese, iyo ine simba rakakosha pakudzivirira uye kutonga kwegirinhi hanyanisi negariki.
1. Zvikonzero zvekuoma muromo
Pane zvikonzero zvakawanda zvekuoma mazano eiii uye garlic miriwo, kunyanya physiological uye pathological. Iwo akaoma matipi ane yakanaka physiological properties anonyanya kukonzerwa nekusanaya kwemvura uye kushomeka kwemvura, uye pathological yakaoma matipi anonyanya kukonzerwa negrey mold uye blight. , Chikonzero chinonyanya kukosha chekuoma muromo mukugadzirwa ndeye grey mold uye blight.
2. Zviratidzo zvikuru
Grey mold inokonzerwa negirini hanyanisi, garlic, leek uye mamwe Anyanisi uye garlic miriwo yakaoma tip inowanzo "green yakaoma", kutanga, pamashizha inokura mavara machena akawanda, kana tembiricha uye hunyoro zvakakodzera, makwapa echirwere anopararira kubva pashizha. tip down, zvichiita kuti mashizha aome. Kana hunyoro hwakakwirira, grey mold layer inogona kuumbwa pamashizha akafa.
Mazano akaomeswa egirini hanyanisi, garlic, leek nemimwe miriwo inokonzerwa nechirwere inowanzo "chena yakaoma". Pakutanga kwechirwere, mavara akasvibira uye machena anoonekwa pamashizha, ayo anova grey uye machena mavara mushure mekuwedzera, uye mashizha ose anosvava pane imwe nguva. Kana kunaya kana kunyorova kwawanda, chirwere chinomera mold yemvere chena; Kana mamiriro ekunze akaoma, white mildew inonyangarika, kubvarura epidermis uye ona woolly white mycelium. Kana hosha yanyanya, munda unooma, semoto.
3. Chikonzero chechirwere
Pasi pemamiriro ekushisa akakodzera, hunyoro hwepamusoro ndicho chikonzero chikuru chekuitika uye kupararira kwe botrytis uye blight. Botrytis cinerea ne Phytophthora kunyanya munguva yechando kana kuti chirimo muvhu rakabatana nemuviri unorwara. Kana kutonhora uye kunyorova kwakakodzera, mabhakitiriya epathogenic anoramba ari pamuviri unorwara anotanga kumera, achibudisa nhamba huru yehyphae uye conidia, iyo inopinda muvhu. Mumuviri wekutambira, uye tora chikafu kubva kumaseru anotambira kana maseru kuti akure nekuberekana.
Iyi conidia kana mycelium inopararira mumunda kuburikidza nemhepo, mvura, mvura yekudiridza, nezvimwewo, uye inoramba ichibata mimwe miti. Pasi pemamiriro ekushisa akakodzera uye hunyoro, kupararira kunopararira nekukurumidza, uye kazhinji kunogona kukonzera chiitiko chikuru mukati memazuva manomwe.
4. Nzira dzekudzivirira
(1) sarudza marudzi asingaurayiwi nezvirwere.
(2), chenesa gadheni, bvisa utachiona munguva kudzivirira kupararira kweutachiona.
(3), teerera kumvura yemumunda, kudzivirira mvura yemumunda.
(4), rima mbesa dzakasimba, isa yakawanda organic fetereza, zvine musoro kushandisa nitrogen, phosphorus, potassium fetiraiza, kuwedzera chirimwa kuramba zvirwere.
(5), yekutanga pfapfaidzo50% carbendazimthe liquid effect yakanaka. 6. Chenesa masara ehurwere mumunda nenguva yabva kukohwewa hanyanisi, moparadza pakati nepakati.
