Phomosis, lossis zonal pom ntawm beets, ua rau pom nws tus kheej feem ntau nyob hauv ib nrab ntawm lub caij cog qoob loo. Nrog rau qhov mob hnyav ntawm phomaosis, kev cog qoob loo tsawg dua li ntawm 39, 7%, lawv qhov hnyav - los ntawm 11, 7 - 19, 1%, cov qoob loo hauv paus qoob loo - los ntawm 29%, thiab cov ntsiab lus qab zib - los ntawm 1, 17 - 1, 58%. Feem ntau, phomosis tawm tsam beet nplooj, uas tau pom tsis muaj zog los ntawm qee yam kab mob lub cev lossis kab mob. Txhawm rau khaws cia cov qoob loo beet, qhov scourge yuav tsum tau tawm tsam

Ob peb lo lus hais txog tus kab mob

Nyob rau qis beet nplooj cuam tshuam los ntawm phomosis, sib npaug necrotic specks tau tsim, nce los ntawm 3 txog 5 hli txoj kab uas hla. Lawv cov xim tuaj yeem yog xim daj lossis daj. Txhua qhov me me loj hlob qeeb, feem ntau sib koom ua ke ntau dua, thiab cov nqaij mos necrotic pib poob tawm ntawm lawv cov chaw. Raws li qhov tshwm sim ntawm cov txheej txheem, cov nplooj qhuav tawm. Qee lub sij hawm tom qab, pycnidia, cov xim dub me me, pib tsim rau ntawm qhov me me.

Ntawm cov qia ntawm cov noob qes, nplooj petioles thiab cov paj tawg paj, tuaj yeem pom necrosis, pom nyob rau hauv daim ntawv ntawm qhov ntev me ntsis xim av me ntsis, maj mam npog nrog pycnidia. Feem ntau, cov kab mob tsis zoo kis mus rau glomeruli ntawm cov noob thiab cuam tshuam rau lub paj ntawm perianth. Ntawm peduncles nrog glomeruli, cov pob me me feem ntau tsis tuaj, tab sis cov cim tuaj yeem pom ntawm lawv. Yog tias cov noob tau kis tom qab sown, qhov no tuaj yeem ua rau muaj kev puas tsuaj loj heev rau beet seedlings.

Thaum khaws beets, cov tsos mob ntawm phomosis tuaj yeem kuaj pom txog ib hlis lossis ob xyoos tom qab tso cov qoob loo hauv paus, thiab qhov kev loj hlob loj ntawm tus kabmob yuav luag txhua lub caij nplooj ntoo hlav. Yog tias koj txiav cov keeb kwm muaj kab mob, tom qab ntawd txiav lawv koj tuaj yeem pom cov tawv nqaij tawv dub, uas qee zaum voids tau tsim nrog cov phab ntsa npog nrog lub teeb xoob xoob. Feem ntau, thaj chaw cuam tshuam nyob rau sab qaum ntawm cov hauv paus qoob loo.

Phomosis yog qhov txaus ntshai loj heev tsis yog hauv cov chaw khaws khoom, tab sis kuj tseem nyob rau ntawm cov noob qes. Yog tias muaj cov kab mob hauv paus cog tau cog, cov noob qes feem ntau puas nrog lawv tom qab tuag.

Tus neeg sawv cev ua rau muaj tus kab mob tsis zoo thiab ua puas tsuaj yog marsupial mushroom Phoma betae AB Frank. Nws cov mycelium feem ntau yog cov ceg tawv thiab tsis muaj xim, qee zaum nrog cov xim daj. Cov kab mob kis rau lub caij nplooj ntoo hlav tseem nyob rau txheej txheej av (qhov tob ntawm nws tshwm sim tuaj yeem yog tsib txog kaum tsib centimeters). Qee lub sij hawm nws tseem muaj lub caij ntuj sov nyob rau hauv daim ntawv ntawm mycelium thiab pycnidia hauv cov hauv paus hniav thiab noob. Ntxiv nrog rau phomosis, cov nceb no tseem muaj peev xwm ua rau cov hauv paus rot thiab qhuav rot ntawm cov hauv paus hniav beet.

Qhov xwm txheej zoo tshaj plaws rau kev txhim kho cov kab mob tau suav tias yog qhov nruab nrab acidity ntawm cov av, pH 7, qhov kub los ntawm kaum tsib mus rau peb caug degrees (hom phiaj, nees nkaum tsib degrees) thiab cov txheeb ze cov pa ntawm huab cua nyob ntawm thaj tsam ntawm 60 txog 70 feem pua. Phomosis tshwj xeeb tshaj yog thoob plaws ntawm cov lus beets hauv thawj thiab xyoo thib ob ntawm lub neej.

Yuav ua li cas sib ntaus

Beets hauv kev cog qoob loo yuav tsum tau muab tso rau hauv txoj hauv kev uas lawv rov qab mus rau lawv thaj av yav dhau los tsis ntxov dua tom qab peb txog plaub xyoos. Nws yog qhov zoo tshaj plaws los cog nws ntawm cov av nruab nrab loamy av, uas yog qhov tshwj xeeb los ntawm cov tshuaj tiv thaiv nruab nrab. Cov nroj tsuag uas muaj kab mob yuav tsum raug tshem tawm ntawm thaj av: ntawm cov noob qes qhov no feem ntau ua tiav ua ntej pib tsim cov qia, thiab ntawm cov ntoo cog qoob loo thoob plaws lub caij cog qoob loo.

Ntawm cov qoob loo beet cuam tshuam los ntawm fomoz, nws yuav zoo rau tsuag ib zaug lossis ob zaug nrog Alto Super. Thiab yog tias pom muaj tus tsos mob thaum ntxov, txau nrog ib feem ntawm Bordeaux kua yuav pab tau zoo.

Koj yuav tsum tau sim sau cov hauv paus qoob loo ua ntej pib ntawm thawj te, vim tias yog tias lawv puas los ntawm te, lawv yuav plam lawv qhov kev tiv thaiv rau ntau yam kab mob. Thiab tsuas yog cov hauv paus hniav noj qab haus huv yuav tsum tau tso rau cia. Ntxiv mus, lawv cov nplooj yuav tsum tau txiav tawm, tawm tsuas yog ib centimeter petioles. Nws yog qhov zoo tshaj los khaws beets hauv cov thawv me me, nphoo nws nrog cov sib xyaw ntawm cov kua qaub thiab cov xuab zeb.
