Ntau lub koom haum thoob ntiaj teb tau kwv yees qhov muaj peev xwm ntawm huab cua phem thiab puas tsuaj thoob ntiaj teb nyob rau lub hlis tsis ntev los no.

Lub xyoo sov tshaj plaws nyob rau hauv cov ntaub ntawv tam sim no yog 2015-2016, thaum lub ntiaj teb tau ntsib El Nino 21 lub hlis, raws li tsab ntawv ceeb toom tshaj tawm los ntawm World Meteorological Organization nyob rau lub Tsib Hlis.

Thaum lub Rau Hli lig, phau ntawv xov xwm xwm tau tshaj tawm tias yog El Nino hnyav, nws muaj peev xwm thawb lub ntiaj teb kub kom sau lossis ze-cov ntaub ntawv siab tshaj 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.

Qee cov tshuaj yuav ua rau muaj kev phom sij ntawm qhov kub thiab txias vim yog ob lub ntsiab lus hauv qab no:

Ua ntej, 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 kub kub, nws yog heev yooj yim mus ua 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 qee qhov kub, ua rau cov tshuaj puas tsuaj.

Qhov thib ob, 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.

1. Abamectin

Abamectin yog tshuaj tua kab tua kab, kab thiab nematodes, thiab tuaj yeem siv los tswj cov kab tsuag ntawm ntau hom nroj tsuag. Nws tuaj yeem ua rau muaj kev cuam tshuam zoo tshaj plaws thaum 20 ℃, tab sis yuav tsum tau ua tib zoo saib xyuas qhov kub thiab txias, tshwj xeeb tshaj yog 38 ℃ saum lub sijhawm siv, uas yooj yim rau kev puas tsuaj rau cov tshuaj, cov nroj tsuag nplooj deformity, me ntsis, qhov tshwm sim ntawm kev txwv kev loj hlob. .

2.Pyraclostrobin

Pyraclostrobin yog ib qho dav spectrum fungicide, nrog rau kev kho mob thiab tiv thaiv cov teebmeem. Yuav muaj kev pheej hmoo ntawm kev puas tsuaj rau cov tshuaj yog tias siv siab concentration.Nws yuav ua rau cov nplooj ntoo hlawv tshwm sim.

3. Nitenpyram

Nitenpyram feem ntau yog siv los tswj cov kab mob stinging thiab yooj yim ua rau kev puas tsuaj rau cov tshuaj thaum kub kub, yog li nws yuav tsum zam. Thiab nws yog qhov zoo dua los txau ntawm qhov kub ntawm qis dua 30 ° C uas yuav tsis ua rau nplooj hlawv thiab lwm yam tshwm sim.

4. Chlorfenapyr

Chlorfenapyr 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). Chlorfenapyr, 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. Fluazinam

Fluazinam tuaj yeem tiv thaiv tau cov kab mob hauv paus o thiab cov pwm grey, thiab nws tuaj yeem tiv thaiv kab tsuag, xws li citrus liab kab laug sab (tus neeg laus, qe), thiab tswj cov nyhuv zoo dua. Fluazinam yuav ua rau kom muaj kev puas tsuaj rau cov tshuaj thaum nws siv nyob rau hauv qhov kub thiab txias, vim hais tias cov kev ua ntawm Fluazinam siab heev. Cov tshuaj kub kub tuaj yeem ua kom cov evaporation ntawm cov dej, sib npaug kom nce cov concentration ntawm cov kua tshuaj.

6.Propargite

Propargite yog nyob rau hauv tsawg acaricide, nrog rau kev sib cuag thiab gastric toxicity, thiab osmotic conduction. Nws tuaj yeem tiv thaiv kab mob zoo tshaj 20 ℃ thaum cov txiv hmab txiv ntoo cog tau yooj yim heev los tsim cov kab mob sunburn saum 25 ℃.

7. Diafenthiuron

Diafenthiuron yog ib hom tshuaj tua kab tshiab thiourea, acaricide, thiab muaj qee yam kev tua qe. Nyob rau lub sijhawm kub siab (siab tshaj 30 ℃) thiab cov av noo siab, nws yuav tsim tshuaj puas tsuaj rau cov nroj tsuag.

Nws yuav tsum raug sau tseg tias qhov tsim nyog siv kub ntawm cov neeg sawv cev saum toj no tsuas yog siv rau kev siv xwb, thiab qhov tshwj xeeb kub kuj yuav tsum tau muab faib ua cov nroj tsuag, thiab qhov tsim nyog kub ntawm qee cov nroj tsuag kuj txawv.

Tab sis 2,4D, Glyphosate thiab Chlorpyrifos muaj txiaj ntsig zoo rau lub caij ntuj sov.
