Lub hli dhau los no, ntau lub koom haum thoob ntiaj teb tau kwv yees qhov muaj peev xwm ntawm huab cua huab cua phem thiab puas tsuaj thoob ntiaj teb. Ib tsab ntawv tshaj tawm los ntawm World Meteorological Organization nyob rau lub Tsib Hlis tau kwv yees tias muaj 98 feem pua txoj kev uas tsawg kawg yog ib qho ntawm tsib xyoos tom ntej no yuav yog qhov sov tshaj plaws hauv cov ntaub ntawv. Lub xyoo sov tshaj plaws nyob rau hauv cov ntaub ntawv tam sim no yog 2015-2016, thaum lub ntiaj teb tau ntsib ib 21- hli ntev El Nino.
Thaum Lub Rau Hli 8, National Oceanic thiab Atmospheric Administration tau tshaj tawm El Nino ceeb toom, tshaj tawm tias qhov xwm txheej huab cua tau tshwm sim lawm. Thaum lub caij ntuj no, muaj 84 feem pua lub caij nyoog uas El Nino yuav "nruab nrab mus rau qhov muaj zog."
Thaum lub Rau Hli lig, phau ntawv xov xwm xwm tau tshaj tawm tias yog El Nino hnyav heev, nws muaj peev xwm thawb lub ntiaj teb kub kom sau los yog ze-cov ntaub ntawv siab hauv 2024.
Thaum Lub Xya Hli 4, Lub Koom Haum Ntiaj Teb Meteorological tau xaus lus tias thawj qhov tshwm sim El Nino nyob rau hauv dej hiav txwv Pacific nyob rau hauv xya xyoo, thiab lub ntiaj teb yuav muaj kev puas tsuaj rau huab cua thiab cov qauv huab cua yuav luag txhua yam.
Cov huab cua yog tshav ntuj thiab kub, thiab cov neeg ua haujlwm saib xyuas yuav tsum tau ntsuas lub hnub tiv thaiv thaum tawm mus thiab ntxiv dej ntxiv rau lub sijhawm. Tsis tas li ntawd, thaum txau cov tshuaj tua kab, peb yuav tsum sim kom tsis txhob muaj lub sijhawm kub, vim tias muaj ntau tus neeg sawv cev siv rau lub sijhawm kub kub, ntawm ib sab, nws yooj yim heev kom pom cov tshuaj puas tsuaj, ntawm qhov tod tes, cov nyhuv txo.
Qee cov tshuaj yuav ua rau muaj kev phom sij ntawm qhov kub thiab txias vim yog ob lub ntsiab lus hauv qab no:
1. nws muaj feem xyuam rau qhov xwm ntawm cov tshuaj
Cov tshuaj tua kab inorganic thiab dej-soluble, permeable tshuaj tua kab, xws li tooj liab sulfate, sulfur hmoov, pob zeb sulfur sib tov, siv nyob rau hauv high kub, nws yog ib qho yooj yim heev ua rau cov tshuaj puas rau cov qoob loo, vim hais tias cov qauv stability ntawm cov tshuaj muaj pes tsawg leeg yuav hloov tom qab ib tug ntau yam ntawm cov tshuaj. qee qhov kub, ua rau cov tshuaj puas tsuaj.
2. nws muaj feem xyuam rau cov qoob loo tsis kam
Cov tshuaj tiv thaiv ntawm cov nplooj tawv ntoo xws li Buxus macrophylla muaj zog dua, thiab cov tshuaj tiv thaiv ntawm cov nroj tsuag nrog nyias cuticle tsis muaj zog, thiab nws yooj yim dua los tsim tshuaj puas tsuaj thaum siv huab cua kub.
Tom ntej no, coj koj kom nkag siab tias cov neeg ua haujlwm twg yuav tsum zam kom tsis txhob siv lub sijhawm kub kub, kom koj tuaj yeem zam qee qhov tsis tsim nyog tshuaj puas tsuaj ntau li ntau tau!
Cov tshuaj tua kab no yuav tsum tsis txhob kub siab:
1. Organophosphorus tshuaj tua kab: Kub kub yuav decompose organophosphorus tshuaj tua kab thiab txo lawv cov nyhuv.
2. Chloropyrethroid tshuaj tua kab: Kub kub yuav decompose chloropyrethroid tshuaj tua kab, txo nws cov nyhuv, tab sis kuj tsim cov pa phem.
3. Fungicide: Kub kub yuav txo qhov ruaj khov ntawm cov fungicide, ua kom nws degrade, yog li txo nws cov bactericidal nyhuv.
Tshwj xeeb:
1. avermectin ua
Avermectin yog tshuaj tua kab tua kab, kab thiab nematodes, thiab tuaj yeem siv los tswj cov kab tsuag ntawm ntau hom nroj tsuag. Avermectin insecticidal effect yog qhov zoo, txog 20 degree thaum siv cov txiaj ntsig zoo, tab sis yuav tsum tau ua tib zoo saib xyuas qhov kub thiab txias yog qhov zoo tshaj plaws tsis txhob siv, tshwj xeeb tshaj yog 38 degree saum lub sijhawm siv, yooj yim heev rau pom cov tshuaj puas tsuaj, ua rau cov nroj tsuag tawm deformity, me ntsis, nres kev loj hlob tshwm sim.
2. Ib. Pyrazoletin
Pyrazole ether ester yog ib tug dav spectrum fungicide, nrog rau kev kho mob thiab kev tiv thaiv los, nyob rau hauv cov nroj tsuag loj hlob thiab siab kub lub sij hawm (txog 37 degree), high humidity tej yam kev mob, yog hais tias kev siv ntawm pyrazole ether ester concentration siab dhau lawm, yuav muaj kev pheej hmoo. ntawm cov tshuaj puas tsuaj, yuav ua rau cov nroj tsuag nplooj hlawv tshwm sim.
3. Trienolamine
Enidine, insecticidal spectrum yog qhov dav, feem ntau yog siv los tswj cov kab mob stinging; Nws yog ib qho yooj yim uas yuav ua rau muaj kev puas tsuaj rau cov tshuaj ntawm qhov kub thiab txias, yog li thaum txau, nws yog qhov zoo tshaj plaws kom tsis txhob muaj qhov kub thiab txias, thiab nws yog qhov zoo dua los xaiv lub sij hawm qis dua 30 ° C rau tshuaj tsuag, thiaj li tsis ua rau nplooj hlawv thiab lwm yam tshwm sim.
4. Tetraponitrile
Chlorfenil yog ib qho tshuaj tua kab dav dav, tshwj xeeb tshaj yog tawm tsam cov kab laus ntawm lepidoptera (rapeseed, beet npauj, thiab lwm yam). Chlorfenil, haum kub txog 20-30 degrees, qhov zoo tshaj plaws nyhuv. Txawm li cas los xij, kev siv chlorfenapyr ntawm qhov kub thiab txias yuav ua rau nplooj hlawv; Cov nplooj siab dua nyob rau sab saum toj kuj muaj kev puas tsuaj rau tshuaj ntau dua.
5. Fluridine
Fluridine muaj txiaj ntsig zoo rau cov kab mob fungal ntau dua thiab cov kab mob qis, tuaj yeem tiv thaiv kab mob downy mildew, grey pwm, anthrax, kab mob hnub qub dub; Kev tiv thaiv ntawm blight, kab mob hauv paus o thiab grey pwm yog qhov tseem ceeb, thiab nws tseem tuaj yeem tiv thaiv kab tsuag, xws li citrus liab kab laug sab (tus neeg laus, qe), thiab kev tswj cov nyhuv zoo dua. Fluridine, siv nyob rau hauv cov huab cua kub, yuav ua rau kom muaj feem ntawm cov tshuaj puas tsuaj, vim hais tias cov kev ua ntawm fluridine yog siab heev, permeability yog zoo heev, kub kub tshuaj, yuav ua rau kom cov evaporation ntawm dej, sib npaug rau cov concentration ntawm cov kua. tshuaj kho mob.
Yog li ntawd, qhov kub thiab txias haum rau kev thov ntawm fluridine yog qhov zoo tshaj plaws ntawm 25 ° C, thiab lub caij ntuj sov tshuaj tsuag yog xaiv ua ntej 9 teev sawv ntxov lossis tom qab 5 teev tsaus ntuj, kom tsis txhob muaj qhov kub thiab txias thaum tav su, thiaj li tsis ua rau cov nroj tsuag deformity thiab contraction.
6. Hexylene mite
Acetylene mite, tsis tshua muaj tshuaj lom acaricide, nrog rau kev sib cuag thiab gastric toxicity, tsis nqus pa thiab osmotic conduction. Rau cov neeg laus mites, yog tias cov mites zoo, cov nyhuv ovicide tsis zoo, feem ntau 20 degree saum toj no siv acetylene mite, cov nyhuv yog zoo, tab sis siab tshaj 25 degree, cov txiv hmab txiv ntoo cog yog heev yooj yim los tsim kab mob sunburn.
7. butyl ether urea
Butyl ether urea yog ib yam tshiab ntawm thiourea insecticide, acaricide, thiab muaj qee yam kev tua qe. Nyob rau lub sijhawm kub siab (siab tshaj 30 degree) thiab cov av noo siab, kev siv butyl ether urea yog ib qho yooj yim los tsim tshuaj puas tsuaj rau cov nroj tsuag.
Nws yuav tsum tau muab sau tseg tias qhov tsim nyog siv kub ntawm cov neeg sawv cev saum toj no yog rau siv xwb, thiab qhov tshwj xeeb kub kuj yuav tsum tau muab faib mus rau hauv cov nroj tsuag, thiab qhov tsim nyog kub ntawm tej nroj tsuag kuj txawv.
