Liab rot ntawm pob kws cobs feem ntau tshwm sim yog tias huab cua huab cua poob qis pom tau tias nyob ze rau theem ntawm kev puv ntawm cov noob lossis nws feem ntau los nag. Thiab cov kab mob hu ua fungus ua rau tus kab mob no txaus ntshai tsis tsuas yog vim nws txo qis cov qoob loo ntawm cov pob kws, tab sis kuj vim tias cov co toxins tso los ntawm nws tuaj yeem kis rau tsiaj thiab tib neeg, ua rau lawv txhim kho cov txiaj ntsig ntawm neurotoxin (ib qho ntawm hom kev puas tsuaj rau cov paj hlwb)
Ob peb lo lus hais txog tus kab mob
Ntawm pob kws nyob rau theem ntawm cov kua txiv hmab txiv ntoo-ua kom siav, cov ntawv tsis zoo rau saum lub pob ntseg tau tawm tsam los ntawm cov kab liab liab, cov xim uas tuaj yeem sib txawv los ntawm lub paj liab mus rau dawb. Maj mam, cov quav hniav no npog tag nrho cov cob. Nov yog qhov liab rot txawv ntawm lwm yam kab mob pob kws, uas feem ntau cuam tshuam rau ib feem ntawm pob ntseg.
Raws li qhov xwm txheej tsis zoo tshwm sim, cov qhwv tau pib ua kom nruj rau cov cobs, qhuav tawm thiab tig xim liab-cib tones. Cov kab tawm tsam los ntawm tus kab mob, raws li txoj cai, tau rhuav tshem tag nrho, thiab thaum muaj kev swb ntxov, lawv tsis txhim kho hlo li. Yog tias cov noob muaj kab mob tau sown, lawv yuav tsis tawg.
Qhov ua rau tus neeg sawv cev liab rot ntawm pob kws cobs yog cov kab mob tsis zoo uas zais cov tshuaj lom lom. Nws hu ua Fusarium graminearum. Cov kab mob no yog txhoj puab heev thiab muaj peev xwm kis tau cov kab noj qab nyob zoo ntawm nws tus kheej.
Cov kab mob hu ua fungus tau khaws cia hauv daim ntawv ntawm stroma feem ntau ntawm cov seem tom qab sau qoob loo: ntawm cov qia nyob ze ntawm cov nodules, ntawm pob ntseg pob ntseg thiab ntawm cov qhwv. Stromas tuaj yeem yog nkag los lossis tiaj tus, thiab sib txawv hauv kev teeb tsa sib txawv kiag li. Lawv txhua tus suav nrog ovoid lossis elliptical perithecia. Nyob rau hauv lawv, nyob rau hauv lem, tsim ntawm lub hnab nrog pathogenic ascospores tshwm sim, tawg nyob ib ncig ntawm lub site nrog pib ntawm lub caij nplooj ntoos hlav. Feem ntau, cov ascospores no tseem kis tau cov qoob loo rau lub caij ntuj no.
Nws yog qhov tsim nyog tias qib ntawm kev puas tsuaj rau pob kws cobs los ntawm cov kab mob muaj teeb meem fungus tsis yog nyob ntawm txhua yam ntawm lawv kev puas tsuaj los ntawm ntau yam kab. Nov yog qhov liab liab txawv ntawm fusarium.
Feem ntau, qhov mob tsis zoo no tuaj yeem pom nyob hauv thaj chaw uas muaj huab cua sov. Nws txoj kev txhim kho tau txhawb nqa mus rau qhov loj los ntawm qhov kub nruab nrab thiab huab cua ntub ntev uas tau tsim thaum lub sijhawm txhim kho pob ntseg. Cov kab mob tshwj xeeb yog muaj zog tshwj xeeb yog tias muaj dej nag ntau txaus nyob hauv ib nrab ntawm lub caij ntuj sov thiab lub caij nplooj zeeg.
Yuav ua li cas sib ntaus
Ntawm qhov kev tiv thaiv tseem ceeb tiv thaiv liab rot ntawm pob kws cobs, kev kho cov noob nrog fungicides tuaj yeem ua qhov txawv (nws yog qhov tshwj xeeb tshaj yog hnav cov noob siv Ventsedor npaj), cog qoob loo tiv taus cov qoob loo thiab ntau yam, txo cov pob kws npauj pej xeem ntawm qhov chaw, ntxiv rau kev ua raws nruj rau cov cai cog qoob loo. Nws yog ib qho tseem ceeb heev uas yuav tsum tau them sai sai rau cov neeg ua ntej hauv kev cog qoob loo, vim tias feem ntau cov kab mob ua rau kis tau cov qoob loo thiab qee yam lwm yam qoob loo. Tsis tas li, tsis muaj qhov xwm txheej yuav tsum tau thov daim ntawv thov nitrogen-muaj chiv ntau tshaj. Zoo, lwm cov chiv yuav tsum tau siv hauv qhov zoo tshaj plaws.
Koj yuav tsum tau sim sau cov qoob loo raws sijhawm, thiab tom qab sau qoob loo ntawm qhov chaw, khawb kom huv. Cov qoob loo nws tus kheej raug xa mus rau cia hauv chav qhuav. Ua ntej khaws cia, pob ntseg tuaj yeem kho nrog tshuaj tua kab pom zoo. Thiab pob ntseg tawm tsam los ntawm liab rot yuav tsum tau muab pov tseg, vim tias lawv tsis tuaj yeem khaws cia, vim tias lawv yuav luag ib txwm muaj dej ntau dhau thiab pwm.
Ib qho tseem ceeb tshaj plaws yog qhov muaj peev xwm cia ntawm cov noob cobs. Cov dej noo ntawm cov pob ntseg no yuav tsum tsis pub tshaj 16%, thaum cov dej noo ntawm cov nplej yuav tsum tsis pub dhau 13%.
