Thaum kawg, kev npau suav tau tshwm sim: lawv ua lub tsev ntoo lossis lub tsev da dej, tso lub tsev ntoo lossis yuav cov rooj tog ntoo. Lub sijhawm dhau mus, thiab zuam, nyem, rustling tau hnov hauv tsev. Nws yog dab tsi, koj xav li cas? Cov lus teb yog yooj yim: beetles pub rau ntoo tau pib nyob rau hauv lub tsev. Muaj ntau ntau hom, tab sis cov kab tsuag tseem ceeb ntawm cov qauv ntoo yog cov kab kab, barbels, grinders, thiab ntoo borers. Phosphine fumigation ntawm lub tsev ntoo tawm tsam kab yog ib txoj hauv kev txaus ntshai tshaj plaws ntawm kev tswj kab tsuag.
Qhia tias lub tsev muaj kab:
- Drilling hmoov (shavings, ntoo hmoov av). Nws tuaj yeem pom ntawm phab ntsa lossis hauv pem teb.
- Tsiv thiab qhov (inlets thiab outlets).
- Suab nrov nrov xws li zuam, rustling, chirping.
Qhov phem tshaj plaws ntawm qhov xwm txheej no yog kev tshem cov kab ntawm koj tus kheej yuav luag tsis yooj yim sua. Txhua txoj hauv kev txhawm rau rhuav tshem cov kab hauv qhov tuab ntawm tsob ntoo yog superficial. Lawv tsis ua mob rau tus menyuam mos, uas nyob hauv cov ntoo tuab thiab noj tsob ntoo sab hauv.
Muaj ob peb lub khwcov lus qhia thiab txoj hauv kev los tua cov kab hauv tsev ntoo, tab sis tom qab kawm qee yam ntawm lawv, peb tsis ntseeg nws cov txiaj ntsig zoo.
Txoj kev ua tsis tau zoo ntawm cov kab muaj xws li
-
Kho nrog cov cua kub thiab txias tshuab hluav taws xob thiab tshuaj tua kab hauv tsev. Cov larva clogs nws txoj kev nrog laum hmoov thiab quav, thiab tsis yog, txawm tias qhov me tshaj plaws aerosol tsuag los ntawm xws li "cork", yuav nkag mus rau hauv txoj kev.
- Syringing a tree with insecticides. Nws kuj yog ib txoj kev dubious heev, vim hais tias tsob ntoo tuag thiab yuav tsis muaj peev xwm kis tau cov khoom ntawm nws tus kheej nrog ib tug tam sim no ntawm resin thiab kua txiv. Yog li ntawd, nws yog ib qhov tsim nyog los laum thiab ncuav cov khoom nyob rau hauv increments ntawm ob peb centimeters. Thiab yog vim li cas lub tsev ua los ntawm ntoo, yog hais tias nws yuav impregnated nrog chemistry?
- Beetle impregnation. Nyob rau theem ntawm tus kab mob, lawv twb tsis zoo, txij li thaum lawv yog superficial thiab tsis muaj peev xwm nkag mus rau hauv lub thickness ntawm ntoo mus rau larva ntawm bark beetle los yog barbel. Ntau hom kev tiv thaiv ntoo los ntawm kab yuav tsum tau siv nyob rau theem ntawm kev tsim kho lossis kev ua ntoo ua kev tiv thaiv.
Nws feem ntau tshwm sim tias cov kab kab kab mob twb tau siv los ua lub tsev ntoo. Cov ntoo, cov laug cam, cov cav ntoo raug puas los ntawm kab kab vim kev cia khoom tsis raug. Nws tsis yog qhov txawv uas cov neeg tsim khoom tsis paub zoo siv cov khoom siv los ntawm kev huv huv ntawm hav zoov puas los ntawm cov kab kab, uas yuav tsum tau hlawv. Ib tsob ntoo zoo li no pheej yig dua thiab pom nws cov neeg yuav khoom sai sai.
Yuav ua li cas yog lub tsev tsim thiab muaj kab nyob hauv? Hauv xyoo tas los no, kev lag luam tshuaj tua kab mobqhov kev pab cuam "Fumigation nrog phosphine ntawm lub tsev ntoo" tshwm. Cia peb kawm seb nws yog dab tsi.
Phosphine fumigation ntawm lub tsev ntoo los ntawm kab
Phosphine fumigation yog kev siv PH3 roj (hydrogen phosphorous), uas belongs rau 1 qib kev phom sij ntawm txhais tau tias (tseem ceeb heev). Txoj kev yog tsim los rau kev puas tsuaj ntawm kab tsuag ntawm cov nplej thiab cov qoob loo. Nws yog siv nyob rau hauv warehouses, elevators thiab stock barns. Txoj kev ua pov thawj tau zoo heev, thiab nws pib siv rau fumigation ntawm cov tsev ntoo.
Cov khoom siv dab tsi yog siv rau kev fumigation?
Tus neeg sawv cev tseem ceeb rau fumigation ntawm cov tsev ntoo thiab cov qauv nrog phosphine los ntawm bark beetles, grinders, ntoo borers thiab lwm yam ntoo kab yog magnesium los yog txhuas phosphide. Lub luag haujlwm fumigation tuam txhab uas muag siv magnesium phosphide raws li nws decomposes kiag li thiab cov residual plua plav tsis muaj hlau phosphide uas yog txaus ntshai. Hauv cov lus yooj yim, tom qab fumigation, koj lub tsev muaj kev nyab xeeb tag nrho, thiab yuav tsis muaj ib qho khoom siv hauv chav tsev.
Koj yuav tsum paub dab tsi ua ntej fumigating lub tsev ntoo nrog phosphine los ntawm kab?
Phosphine yog cov roj hauv daim ntawv npaj (cov ntsiav tshuaj, daim kab xev, daim hlau). Nws yog qhov tuag taus thiab yog nyob rau hauv chav kawm 1 txaus ntshai, yog li tsuas yog cov neeg uas muaj kev cob qhia tshaj lij tuaj yeem siv nws. Siv cov khoom fumigation los ntawm koj tus kheej lossis los ntawm cov neeg uas tsis muaj daim ntawv pov thawj ntawm kev cob qhia tshwj xeeb,txais tsis tau. Tsis tas li ntawd, lub tuam txhab yuav tsum yog ib tug tswv cuab ntawm National Organization of Disinfectionists (NP "NOD") thiab muaj daim ntawv pov thawj lees paub qhov no.
Fumigation kav ntev li ob peb hnub (los ntawm 5 txog 7) thiab ua tiav tshwj xeeb ntawm qhov ntsuas kub zoo. Yog li, kev pabcuam yog nruj me ntsis raws caij nyoog thiab tsis tuaj yeem nqa tawm thaum lub caij ntuj no. Gas los ntawm beetles tsuas yog tso tawm ntawm qhov kub thiab txias.
Rau lub sijhawm ntawm fumigation, koj yuav tsum tawm hauv chav, thiab koj tsis tuaj yeem nkag mus rau tag nrho lub sijhawm raug. Tsuas yog tom qab tus kws tshaj lij fumigation tuaj txog zaum ob thiab nqa tawm degassing (tshem tawm cov khoom siv hlau phosphine nyob hauv chav), koj tuaj yeem siv lub tsev.
Vim li cas phosphine fumigation yog txoj hauv kev zoo tshaj?
Phosphine lossis hydrogen phosphide tso tawm thaum lub sijhawm ua haujlwm hauv tsev (fumigation) yog ib qho chaw txaus ntshai heev thiab muaj tshuaj lom rau txhua yam muaj sia. Qhov me ntsis concentration ntawm cov roj yog txaus los tua tag nrho cov muaj sia nyob hauv cheeb tsam ntawm nws qhov kev ua. Txij li thaum cov pa roj yog 1.5 npaug hnyav dua huab cua, nws, nyem tawm ntawm huab cua, nkag mus rau tag nrho cov kab lus thiab nkag mus rau tag nrho cov larvae thiab kab hauv chav, tawm hauv lawv tsis muaj caij nyoog. Lawv tuag los ntawm kev lom lom lom, uas tsis tuaj yeem ua tiav siv lwm txoj hauv kev lossis tshuaj tua kab.
Yuav ua li cas xaiv lub tuam txhab fumigation
- Daim ntawv pov thawj ntawm kev cob qhia cov neeg ua haujlwm (nrog rau kev fumigation).
- Certificate of membership in the National Organization of Disinfectionists (NP "NOD").
