Potato chirwere: chii chinofanira kuva kutya?

Potato tubers dzingave dzawirwa nezvirwere zvakasiyana-siyana izvo zviri kukonzerwa notumwe, utachiona, mabhakitiriya. Zvirwere izvi mhando kuderedza zvikuru kukura nembatatisi, kuderedza goho uye kukanganisa unhu muchero. Saka zvirwere mbatatisi uye maonero avo vanofanira kuziva munhu ari kuronga kukura uye kuwana gohwo rakanaka.

Zvirwere mbatatisi tubers, anokonzera vakawanda hanya kuti Chikwata uye konzera rinorema kukuvara krneplodam - zviri kunonoka nenyunje, blackleg, panowanikwa mhete ora uye siyana utachiwana zvirwere. Unofanira kuva uchiziva pathologies izvi zvizere.

Saka, mushakabvu nenyunje (Phytophthora kana), izvo zviri kukonzerwa neVadzidzi chakuvhe - chirwere kuti unowanikwa mukupera July - mangwanani August uye kunoratidzwa muchimiro chitarisiko shava makwapa mashizha uye madzinde. Kana ukawedzera mhepo mwando kana dova madonhwe, marimu makwapa akasvibirika akafukidza chena akanzwa unhani. Tuber vakaumba specks mwoyo grayish vatungamiriri kuti chokwadi chokuti tubers nokuora zvachose. chirwere ichi kuburikidza mvura mvura kana pakutanga utachiona mashizha, uye ipapo tuber. Zviratidzo chirwere matapiri okutanga kuonekwa pakarepo, asi mazuva chete pashure 14-21 mushure chirwere.

Kana uremu zvacherechedzwa, anoona asati anochera nembatatisi, zvakakodzera mwaya misoro mhangura sulfate (10g muna 5 litres mvura). Yeuka kuti akarova matapiri haagoni papera kushandiswa sezvo mbeu uye kudyara ivhu anogona kushandiswazve chete pashure makore mashomanana. The mberi zvichaitirwa matapiri kunobva yakarurama okuchengetera. Saka, kukura chirwere panguva kuchengetera matapiri (Phytophthora) kunogona kuitika kana kuchengetera tembiricha iri madhigirii anenge 19. Zvikuru mamiriro ezvinhu akanaka nokuda tuber vachengetedzwe - tembiricha mukuru 3 madhigirii, uye mwando - kwete kwakakwirira 80%.

Next zvakafanana chirwere - blackleg chirwere icho kuitwa kwemabhakitiriya. Chirwere chinhu akura tuber uye kunoratidzwa muna yellowing mashizha, midzi akafa uye chiedza mbatatisi muedzo-panze. Kana chirimwa achiri kutapukirwa vachiri padanho kuibvisa, ane kwete tubers. Kunze weboka chirwere hakuiti unooneka. Kubva pakati mbatatisi rots, hwosvava.

Ring ora chokuita kwemabhakitiriya chirwere pamusoro matapiri. Rinotanga kuoneka pashure maruva, kana pane chinoshingaira wilting mashizha. Ipapo madzinde ichasvava. Kana matapiri zvinochengetwa ari sectional payo tichingoda dzinoorera pazvindori vascular mwanda. Chirwere nechirwere ichi kazhinji kunoitika somugumisiro zvokuimba zvakakanganiswa panguva paungano chirimwa. Gare gare, kana utachiona tubers vari pasi kumhara, maperembudzi inoparadzirwa zvimwe utano.

Kudzivisa zvirwere zvakasiyana-siyana vasati raizoiswa kuchengetera nzvimbo yacho tubers anofanira kwazvo yaoma panze uye kugadzirisa.

Chimwe chezvinhu ngozi chirwere matapiri chinhu kenza kuti anochengeterwa ivhu kusvika makore makumi maviri pashure chirwere. The causative nomumiririri chiri chakuvhe kuti ngozi kwazvo rangano. Kenza Zviratidzo: mashava growths pamusoro tuber, izvo kupfuura ukuru matapiri. Chinetso ndechokuti tuber kuora, chirwere hwacho ivhu, uye zvakananga kavha yacho tubers yasara. The chikuru chenjedzo - kuonekwa kuti foci chirwere nekukurumidza uye nokusima mbatatisi mhando husingakwanisi kenza. Kana zvakanaka chinjana tsika, chirwere haisi sehwakajairika.

All chirwere mbatatisi, dzakakomba zvikuru zvacho zvinorondedzerwa pamusoro, anechekuita zvinokuvadza kwazvo zvirimwa uye kutungamirira kurufu tubers. Basa murimi - nenguva vasabatwa chirwere huve uye kuitisa matanho.
