Kushandiswa
Mishonga yezvipembenene ine spectrum yakafara. Mishonga yekuuraya zvipembenene ine basa rekufuridzira inogona kuodza methyl isothiocyanate, formaldehyde uye hydrogen sulfide muvhu, uye ine simba rekuuraya rhizoma nematode, stem nematode uye heteroderma nematode. Pamusoro pezvo, ine simba rekuuraya zvipembenene, kuuraya mabhakitiriya uye kuuraya mishonga yekuuraya zvipembenene, saka inogonawo kurapa howa dzemuvhu, zvipembenene zvepasi pevhu uye sora re chenopodium, senge potato rhizoctonia, zvipembenene zve soil polypteroptera, kowbeetles, May scarab larvae nezvimwewo. Ichishandisa 98% particulate agent 750 ~ 900g/100m2 jecha ivhu, 900 ~ 1050g/100m2 ivhu senzira yekurapa ivhu, kupararira kana kushandisa mugero, Chemicalbook inogona kudzora chirwere chemuriwo ne peanut nematode. 75% wettable powder 1125g/100m2 inogona kushandiswa kudzora chirwere che potato root nematode.
Ivhu rinofuridzira fumigant, methyl thioisothiocyanate nematocide, uye zvakare kurapa fungus, zvipembenene zvepasi pevhu nemasora, anozivikanwawo sekukurumidza kupera. Chigadzirwa ichi chinoora muvhu kuti chigadzire methylaminomethyl dithiocarbamate, uye zvakare kuti chigadzire methyl isothiocyanate. Chinogona kudzora zvinobudirira zvipembenene nefungus zvevhu, zvakaita secataplexy bacteria, filarial bacteria, fusarium, nezvimwewo, uye chinogonawo kudzivirira kukura kwemasora akawanda. Chine simba rakanaka rekudzora zvipembenene zvedonje yellow blight.
Maitiro ekuuraya utachiona
(1) Usati washandisa Dazomet, chenesa midzi yechirimwa chekupedzisira, woisa fetereza inodiwa nechirimwa chinotevera.
(2) Iva nechokwadi chekuti hunyoro hwevhu hwasvika pa50-60% yehunyoro hwemvura yemumunda, kana hukasasvika padanho rakatarwa, unogona kuisa mvura mumunda; mazuva matatu kusvika mashanu mushure mekudiridza, shandisa muchina uyu kutenderedza nekupwanya ivhu kuti uve nechokwadi chekuti ivhu rinopinda mvura.
(3) Pakushandisa Dazomet, tembiricha yakakodzera yevhu i12-18°C, uye tembiricha shoma haifanirwe kunge iri pasi pe6°C.
(4) Shandisa 25-40g yeDazomet pa square mita imwe neimwe yemunda. Pakati pazvo, kushandisa cucumber, sweet pepper, pepper greenhouse zvinorema 20-25kg/mu, kushandisa domasi greenhouse zvinorema 25-30kg/mu, uye kushandisa sitrobheri greenhouse zvinorema 15-20kg/mu.
(5) Isa mushonga zvakaenzana pamusoro, wobva washandisa rotary gejo pakurima kunotenderera (kudzika kwaro i25-30cm), kuitira kuti Dazomet rikwire ibatane zvizere nepurazi rekurima kuti ibudirire zvakanyanya. Kana root knot nematode ikaitika zvakakomba, rotary tillage kudzika kwaro kunofanira kunge kuri 40cm, uye muganho wepamusoro wekushandisa mushonga unofanira kuiswa.
(6) Mushure mekushandisa, mvura inopfapfaidzwa pamusoro kuti ibudise gasi rekuuraya utachiona (methyl isothiocyanate, formaldehyde uye hydrogen sulfide).
(7) Fukidza firimu (ukobvu haufanirwe kunge huri pasi pe6 siriki), wobva wadzvanya firimu nevhu idzva, usarega gasi rekuuraya utachiona richibuda, uye chengetedza tembiricha yevhu iri pa10cm pa20℃, vhara hutachiona kwemazuva angangoita 15-20 (kana mamiriro ekunze asina kudziya, nguva yekutsvaira inofanira kuwedzerwa).
(8) Mushure mekubvisa utachiona, vhura firimu racho, uye shandisa rotary gejo kufefetedza ivhu, buritsa magasi ane chepfu asara muvhu, kazhinji fefetedza kwemazuva angangoita gumi nemashanu (kana mamiriro ekunze achitonhora uye akanyorova, wedzera nguva yefefetedza, kana mamiriro ekunze achipisa uye akaoma, deredza nguva yefefetedza).
(9) Mbeu dzinogona kudyarwa mushure mekucheneswa.
Maitiro eDazomet boom
1. Dazomet mushonga wekuuraya zvipembenene une hunyoro hwakasiyana-siyana, une hunyoro hwakanyanya uye hauna tsvina.
2. Kana ikashandiswa muvhu rakanyorova, inoora kuita methyl isothiocyanate ine chepfu, formaldehyde uye hydrogen sulfide muvhu, uye inopararira nekukurumidza kuzvidimbu zvevhu, ichiuraya zvinobudirira mhando dzakasiyana dzemafungu, hutachiona, zvipembenene zvepasi pevhu uye mbeu dzemasora dzinomera muvhu, kuitira kuti ivhu rive nemhedzisiro yekuchenesa ivhu.
3. Kushandiswa kwacho kunokanganiswa zvakanyanya nekupisa kwevhu nehunyoro uye chimiro chevhu, kushandiswa kwekupisa kwevhu kunofanira kupfuura 12 ° C, 12-30 ° C ndiyo yakakodzera, hunyoro hwevhu hunopfuura 40% (hunyoro hwevhu hunogona kuumbwa nemaoko, kukwirira kwemita imwe chete kunogona kuparadzirwa mushure mekudonha pasi sezvinodiwa).
