Shizha chlorosis: tsananguro, mapikicha, kudzora nzira

Chero webindu nematambudziko izwi akadai nyoro chlorosis. Plant chirwere kunooneka pacharo muimba tyisa (-season) yellowing uye mashizha kuwa. Chikonzero hosha iri kutyora chlorophyll inotungamirwa, saka - kuderedza basa photosynthesis. Mashizha saka anogona kurasikirwa ruvara, kwete zvachose chete asiwo zvishomanana uye itsva (diki) nhungirwa uye mashizha todzokera zvinooneka. Kumicheto mashizha chipande zvinowanzooneka vakamonyanisa, akaumba atwo (namavara) vari akaremara. kupfura Mazano vari kana simba chaizvo kana shrunken.

Shizha chlorosis anogona kuva chirwere (zvinoita kusvibiswa nezvimwe zvinomera) uye non-chirwere (kubva kutyorwa kurima tsika). Funga chlorosis zvizere.

Chokutanga - shizha chlorosis (Photo utachiona miti), apo, somuenzaniso - mizambiringa:

Zvirwere chlorosis kuti mazambiringa mashizha

Chikwata vanouti "shizha blotch" uye "tsvuku waMosesi". Rinoreva kuti chirwere nemavhairasi chirwere degeneration. Nokuti muzambiringa chirwere chakakomba zvikuru ngozi (shizha rinopfungaira, nemavhairasi korotkouzlie, rufu chirimwa). Mumakwenzi pachena chlorosis utachiona, kuva yeyero ndimu. The mutsinga mashizha, kusiyana zvatinosiita chlorosis, rakabuda ruvara. Kana korotkouzliya interstices saizi iri yekudyidzana akaderedzwa, mashizha todzokera, yekudyidzana zvakawedzera inotungamirwa laterals. Kana waMosesi muzambiringa mashizha, rakabuda ruvara pamwe mutsinga, uye vanodzokera wrap (yakakoswa).

Kuzvidzora matanho, dziviriro

Neutachiona chirimwa pakarepo Dzurwa, ivhu etched dichloroethane (residues). Kudzivisa chidzoke uye kupararira chlorosis chinhu kunyatsosarudza kuti yokudyara zvinhu (mizambiringa, izvo aronga usimwe ramangwana, vari kumorwa kubva pamakwenzi zvachose utano uye vakasimba). Kuti usarudze bogmærke yemizambiringa nzvimbo isina nematodes, inova Vatakuri chikuru utachiwana. Umo kare hwakanyorwa zviitiko panomuka zvirwere utachiona, Zvinokurudzirwa kuti kudyara mbeu (kusvika makore matanhatu panhurikidzwa) kuti nematodes havadyi.

Chlorosis romuzvarirwo (non-rwarisa)

Zvakasiyana zvishoma kubva chirwere. Pano zvakare pane yellowing mashizha, asi mutsinga vanoramba girini. The zvachose ikure chirimwa yekudyidzana hwakaipa panguva imwecheteyo, pane zvikuru zhinji mizambiringa yakabva kumwe (kunyanya - rezasi chikamu mugwenzi). The kukonzera non-zvinotapukira chlorosis riri hunenge chirimwa muviri chokuita zvakanyanya mwando, zvizhinji kwesuko, alkaline maitiro ivhu, asi kakawanda - kusava simbi.

Kuzvidzora matanho, dziviriro

Kana doro kwesuko rokuita Ammonium sulfate (3 makirogiramu pasi gwenzi mazambiringa). Varumbidzwa kusonanidzwa rootstocks nemishonga madota ivhu (kupfuura akaratidza 41-B Chasselas musi Berlandieri). With zvakawandisa mwando zvinogona kudzorwa ne kutimba (nokukurumidza evaporating mvura zvakawandisa). Kana wako nzvimbo yakawedzera kunonaya, pakutanga tsvaka mhando husingakwanisi chlorosis.

Uyezve akakurudzira kuti:

- pakatanga kwematsutso sulfate muvhu (kurudyi pasi mugwenzi, 500 magiramu);

- spraying sulphate (0.5%) muchirimo, iri kukura mwaka (pachinzvimbo sulfate zvinogona kushandiswa simbi chelator, riri nani);

- usanganidzo yakaoma kuberekesa (micro- uye macro-) pamwe manganese, simbi, zinc.
