Zvikonzero Zvikuru zveDazomet 98% Tc

Application

Mishonga yezvipembenene yakakura. Iyo nematocides ine fumigation function inogona kuora methyl isothiocyanate, formaldehyde uye hydrogen sulfide muvhu, uye ine kuuraya rhizoma nematode, stem nematode uye heteroderma nematode. Mukuwedzera, ine insecticidal, bactericidal uye herbicidal effects, saka inogonawo kubata fungi yevhu, zvipembenene zvepasi uye chenopodium sora, zvakadai sembatatisi rhizoctonia, ivhu re polypteroptera zvipembenene, kowbeetles, May scarab larvae nezvimwe zvakadaro. Kushandisa 98% particulate agent 750 ~ 900g/100m2 ivhu rejecha, 900 ~ 1050g/100m2 ivhu sekurapa kwevhu, kupararira kana mugero kushandiswa, Chemicalbook inogona kudzora miriwo uye nzungu nematode chirwere. 75% wettable powder 1125g/100m2 inogona kushandiswa kudzora chirwere chembatatisi nematode.
Soil fumigant, methyl thioisothiocyanate nematocide, uye zvakare kurapa fungi, zvipembenene zvepasi pevhu nemasora, anozivikanwawo sekutsakatika nekukurumidza. Chigadzirwa chacho chakaora muvhu kuita methylaminomethyl dithiocarbamate, uyezve kugadzira methyl isothiocyanate. Inogona kunyatso kudzora nematodes uye fungi yevhu, senge cataplexy bacteria, filarial bacteria, fusarium, nezvimwewo, uye inogonawo kutadzisa kukura kwemasora mazhinji. Iyo ine yakanaka kudzora maitiro pakotoni yeyero blight.

Disinfection process

(1) Usati washandisa Dazomet, chenesa midzi yechirimwa chekupedzisira, uye isa fetereza yepasi inodiwa nechirimwa chinotevera.
(2) Ita shuwa kuti hunyoro hwevhu hunosvika pa50-60% yemvura yemumunda, kana isingaenderane nechiyero, unogona kupinza mvura mumunda; 3-5 mazuva mushure mekudiridza, shandisa muchina kutenderedza nekupwanya ivhu kuti uve nechokwadi chekupinda kwevhu.
(3) Paunenge uchishandisa Dazomet, tembiricha yakakodzera yevhu i12-18 ° C, uye iyo shoma haigone kuve isingasviki 6 ° C.
(4) Shandisa 25-40g yeDazomet per square metre yevhu. Pakati pavo, kushandiswa kwegaka, pepper inotapira, pepper greenhouse ndeye 20-25kg / mu, kushandiswa kwemadomasi greenhouse ndeye 25-30kg / mu, uye kushandiswa kwestrawberry greenhouse ndeye 15-20kg / mu.
(5) Isa mushonga wacho zvakaenzana pamusoro, wozoshandisa gejo rekutenderedza kutenderedza tillage (kudzika kuri 25-30cm), kuitira kuti Dazomet inosimuka inyatsobatana nejira rekurima kuti ribudirire zvakanyanya. Kana mudzi wepfundo nematode ukaitika zvakakomba, kudzika kwe rotary tillage kunofanira kuita 40cm, uye muganho wepamusoro wekushandisa zvinodhaka unofanirwa kuiswa.
(6) Mushure mekushandiswa, mvura inopfapfaidzwa pamusoro kuti ibudise gasi rekuuraya utachiona (methyl isothiocyanate, formaldehyde uye hydrogen sulfide).
(7) Fukidza firimu (ukobvu hahufaniri kuva pasi pe6 silika), wozobatanidza firimu nevhu idzva, usarega gasi re disinfection richibuda kunze, uye chengetedza tembiricha yevhu pa10cm pa20 ℃, yakavharwa disinfection kwemazuva anenge 15-20 (mumamiriro ekunze ekushisa, nguva yefumigation inofanira kuwedzerwa).
(8) Kana mapedza kuuraya utachiona, fukurai firimu racho, uye shandisai gejo rekutenderera kufefetedza ivhu, buritsa magasi ane chepfu asara muvhu, kazhinji pinza mweya kwemazuva anenge 15 (apo kunze kunenge kuchitonhora nekunyorova, wedzera nguva yekufema, kana kunze kuchipisa uye kwakaoma, kuderedza nguva yekufema).
(9) Mbeu dzinogona kudyarwa mushure mekuuraya utachiona.

Mechanism yeDazomet boom

1. Dazomet is an environment friendly friendly wide-spectrum comprehensive ivhu fumigation disinfectant ine hunyanzvi hwepamusoro, hupfu hwakaderera uye pasina chasara.
2. Kana yakashandiswa kune ivhu rakanyorova, inosvibiswa kuita toxic methyl isothiocyanate, formaldehyde uye hydrogen sulfide muvhu, uye inokurumidza kupararira kune zvimedu zvevhu, zvinobudirira kuuraya nematodes dzakasiyana-siyana, zvirwere, zvipembenene zvepasi uye kumera mbeu yemasora muvhu, kuitira kuti iwane mhedzisiro yekuchenesa ivhu.
3. kushandiswa kunonyanya kukanganiswa nekushisa kwevhu uye hunyoro uye chimiro chevhu, kushandiswa kwekushisa kwevhu kunofanira kunge kwakakura kudarika 12 ° C, 12-30 ° C ndiyo inonyanya kukodzera, hunyoro hwevhu hunopfuura 40% (kunyorova kune ruoko pinch ivhu kunogona kuumba boka, 1 mita kureba inogona kuparadzirwa mushure mekuwira pasi seyero).
