Cov teebmeem zoo rau Dazomet 98% Tc

Daim ntawv thov

Broad-spectrum tshuaj tua kab. Cov nematocides nrog fumigation muaj nuj nqi tuaj yeem decompose methyl isothiocyanate, formaldehyde thiab hydrogen sulfide hauv av, thiab tua cov nyhuv ntawm rhizoma nematode, qia nematode thiab heteroderma nematode. Tsis tas li ntawd, nws muaj cov tshuaj tua kab, kab mob thiab tshuaj tua kab mob, yog li nws tuaj yeem kho cov av fungi, kab tsuag hauv av thiab cov nroj tsuag chenopodium, xws li qos yaj ywm rhizoctonia, av polypteroptera kab, kowbetles, May scarab larvae thiab lwm yam. Siv 98% tus neeg saib xyuas 750 ~ 900g / 100m2 xuab zeb av, 900 ~ 1050g / 100m2 av nplaum raws li kev kho av, kis lossis trench daim ntawv thov, Tshuaj muaj peev xwm tswj tau zaub thiab txiv laum huab xeeb nematode kab mob. 75% wettable hmoov 1125g / 100m2 tuaj yeem siv los tswj cov qos yaj ywm hauv paus nematode.
Av fumigant, methyl thioisothiocyanate nematocide, thiab tseem kho cov kab mob, kab tsuag hauv av thiab cov nroj tsuag, tseem hu ua kev tuag sai. Cov khoom yog decomposed nyob rau hauv av los tsim methylaminomethyl dithiocarbamate, thiab ntxiv mus rau methyl isothiocyanate. Nws tuaj yeem tswj tau cov kab mob nematodes thiab av fungi, xws li kab mob cataplexy, kab mob filarial, fusarium, thiab lwm yam, thiab tuaj yeem cuam tshuam kev loj hlob ntawm ntau cov nroj tsuag. Nws muaj kev tswj tau zoo ntawm paj rwb daj blight.

Cov txheej txheem tua kab mob

(1) Ua ntej siv Dazomet, ntxuav cov hauv paus hniav ntawm cov qoob loo kawg, thiab siv cov chiv chiv uas yuav tsum tau ua los ntawm cov qoob loo tom ntej.
(2) xyuas kom meej tias cov dej noo ntawm cov av ncav cuag li 50-60% ntawm thaj av muaj peev xwm, yog tias nws tsis ua raws li tus qauv, koj tuaj yeem txhaj dej rau hauv thaj teb; 3-5 hnub tom qab tso dej, siv lub tshuab tig thiab rhuav tshem cov av kom ntseeg tau tias cov av permeability.
(3) Thaum siv Dazomet, qhov kub ntawm qhov tsim nyog ntawm cov av yog 12-18 ° C, thiab qhov tsawg kawg nkaus tsis tuaj yeem qis dua 6 ° C.
(4) Siv 25-40g ntawm Dazomet ib square meter ntawm av. Ntawm lawv, kev siv dib, kua txob qab zib, kua txob tsev cog khoom yog 20-25kg / mu, kev siv lub tsev cog qoob loo yog 25-30kg / mu, thiab kev siv strawberry tsev cog khoom yog 15-20kg / mu.
(5) Siv cov tshuaj sib npaug rau ntawm qhov chaw, thiab tom qab ntawd siv cov plowing teb rau cov tillage teb (qhov tob yog 25-30cm), kom Dazomet nce siab nyob rau hauv kev sib cuag nrog plowing txheej kom ua tiav qhov siab tshaj plaws. Yog hais tias lub hauv paus pob caus nematode tshwm sim tiag, qhov tob tillage yuav tsum yog 40cm, thiab sab sauv txwv ntawm kev siv tshuaj yuav tsum tau siv.
(6) Tom qab thov, dej yog txau rau ntawm qhov chaw los tsim cov tshuaj tua kab mob (methyl isothiocyanate, formaldehyde thiab hydrogen sulfide).
(7) Npog zaj duab xis (thickness yuav tsum tsis pub tsawg tshaj 6 lo lo ntxhuav), tom qab ntawd cog cov zaj duab xis nrog cov av tshiab, tsis txhob cia cov tshuaj tua kab mob tawm, thiab khaws cov av ntawm qhov kub ntawm 10cm ntawm 20 ℃, kaw tshuaj tua kab mob li 15-20 hnub (nyob rau hauv huab cua kub, lub sij hawm fumigation yuav tsum tau txuas ntxiv).
(8) Tom qab tshuaj tua kab mob, tshem tawm cov yeeb yaj kiab, thiab siv lub tshuab ua pa kom ua pa rau hauv av, tso cov pa phem uas tseem tshuav hauv cov av, feem ntau ua cua sov li 15 hnub (thaum huab cua txias thiab ntub dej, ncua lub sijhawm cua txias, thaum huab cua kub thiab qhuav, txo lub sij hawm cua).
(9) Cov noob tuaj yeem sown tom qab tshuaj tua kab mob.

Mechanism ntawm Dazomet boom

1. Dazomet yog ib puag ncig tus phooj ywg broad-spectrum comprehensive av fumigation tshuaj tua kab mob nrog high efficiency, tsis tshua muaj toxicity thiab tsis muaj residue.
2. Thaum siv rau cov av ntub, nws tau decomposed rau hauv tshuaj lom methyl isothiocyanate, formaldehyde thiab hydrogen sulfide nyob rau hauv cov av, thiab sai sai kis mus rau cov av hais, zoo tua ntau yam nematodes, pathogens, underground pests thiab germination nroj tsuag noob nyob rau hauv cov av, thiaj li mus cuag cov nyhuv ntawm tu cov av.
3. daim ntawv thov muaj kev cuam tshuam zoo heev los ntawm cov av kub thiab av noo thiab cov qauv av, kev siv cov av kub yuav tsum siab tshaj 12 ° C, 12-30 ° C yog qhov tsim nyog tshaj plaws, av av noo ntau dua 40% (humidity rau tes pinch av tuaj yeem tsim ib pawg, 1 meter qhov siab tuaj yeem sib cais tom qab ntog rau hauv av raws li tus qauv).
