Meriana e bolaeang likokoanyana e pharalletseng. Li-nematocide tse nang le ts'ebetso ea ho fumigation li ka bola methyl isothiocyanate, formaldehyde le hydrogen sulfide mobung, 'me li be le phello e bolaeang ho rhizoma nematode, stem nematode le heteroderma nematode. Ho phaella moo, e na le liphello tse bolaeang likokoanyana, bactericidal le herbicidal, kahoo e ka boela ea tšoara li-fungus tsa mobu, tse senyang lijalo ka tlas'a lefatše le mofoka oa chenopodium, joalo ka litapole rhizoctonia, likokoanyana tsa mobu oa polypteroptera, kowbeetles, May scarab larvae joalo-joalo. Ho sebelisa 98% ea likaroloana tse 750 ~ 900g/100m2 mobu oa lehlabathe, letsopa la 900 ~ 1050g/100m2 joalo ka kalafo ea mobu, ts'ebetso ea ho jala kapa ea foro, Chemicalbook e ka laola lefu la meroho le peanut nematode. 75% phofo e metsi 1125g/100m2 e ka sebelisoa ho laola lefu la nematode ea metso ea litapole.
Mobu oa fumigant, methyl thioisothiocyanate nematocide, hape le ho phekola li-fungus, likokoanyana tse ka tlas'a lefatše le lehola, tse tsejoang hape e le ho fela kapele. Sehlahisoa se bolile mobung ho etsa methylaminomethyl dithiocarbamate, le ho feta ho theha methyl isothiocyanate. E ka laola ka katleho li-nematode le li-fungus tsa mobu, joalo ka baktheria ea cataplexy, filarial bacteria, fusarium, joalo-joalo, hape e ka thibela kholo ea lehola le lengata. E na le phello e ntle ea taolo holim'a k'hothone e mosehla blight.
Mokhoa oa ho thibela likokoana-hloko
(1) Pele o sebelisa Dazomet, hloekisa metso ea lijalo tsa ho qetela, 'me u sebelise manyolo a motheo a hlokoang ke lijalo tse latelang.
(2) Etsa bonnete ba hore mongobo oa mobu o fihla ho hoo e ka bang 50-60% ea matla a metsi a tšimo, haeba a sa finyelle maemo, u ka kenya metsi tšimong; Matsatsi a 3-5 ka mor'a ho nosetsa, sebelisa mochine ho fetola le ho pshatla mobu ho netefatsa ho kenella ha mobu.
(3) Ha u sebelisa Dazomet, mocheso o loketseng oa mobu ke 12-18 ° C, 'me bonyane bo ka se be ka tlase ho 6 ° C.
(4) Sebelisa 25-40g ea Dazomet ka square meter ea naha. Har'a tsona, tšebeliso ea likomkomere, pepere e monate, sethopo sa pepere ke 20-25kg / mu, tšebeliso ea sethopo sa tamati ke 25-30kg / mu, le tšebeliso ea sethopo sa fragola ke 15-20kg / mu.
(5) Sebelisa lithethefatsi ka mokhoa o ts'oanang holim'a metsi, ebe u sebelisa mohoma oa rotary bakeng sa phehoa ea rotary (botebo ke 25-30cm), e le hore ho phahama ha Dazomet ho kopane ka ho feletseng le lera la ho lema ho finyella katleho e kholo. Haeba lefito la motso le nematode le hlaha ka botebo, botebo ba rotary tillage e lokela ho ba 40cm, 'me moeli o ka holimo oa tšebeliso ea lithethefatsi o lokela ho sebelisoa.
(6) Kamora ho sebelisoa, metsi a fafatsoa ka holim'a metsi ho hlahisa khase e bolaeang likokoana-hloko (methyl isothiocyanate, formaldehyde le hydrogen sulfide).
(7) Koahela filimi (botenya bo se ke ba e-ba ka tlase ho silika ea 6), ebe u kopanya filimi ka mobu o mocha, u se ke ua lumella khase ea disinfection hore e tsoe, 'me u boloke mocheso oa mobu o le 10cm ho 20 ℃, ho thibela likokoana-hloko ka matsatsi a ka bang 15-20 (ka mocheso o tlase, nako ea fumigation e lokela ho atolosoa).
(8) Ka mor’a ho bolaea likokoana-hloko, koaholla filimi, ’me u sebelise mohoma oa rotary ho kenya moea mobung, u lokolle likhase tse chefo tse setseng mobung, hangata li kenya moea ka matsatsi a ka bang 15 (ha boemo ba leholimo bo bata ’me bo le mongobo, lelefatsa nako ea moea, ha boemo ba leholimo bo chesa ’me bo omile, fokotsa nako ea moea oa moea).
(9) Peō e ka jaloa ka mor'a hore ho bolaoe likokoana-hloko.
Mokhoa oa ho ntlafatsa Dazomet
1. Dazomet ke sebolaea-mafu se nang le tikoloho e pharalletseng se nang le sebolaea-mafu se nang le matla a holimo, se nang le chefo e tlase ebile ha se na masala.
2. Ha e sebelisoa mobung o mongobo, e qhibiliha ka chefo ea methyl isothiocyanate, formaldehyde le hydrogen sulfide mobung, 'me e ata ka potlako ho likaroloana tsa mobu, ka katleho e bolaea li-nematode tse sa tšoaneng, likokoana-hloko, likokoanyana tse ka tlas'a lefatše le ho mela peo ea mofoka mobung, e le ho finyella phello ea ho hloekisa mobu.
3. kopo e angoa haholo ke mocheso oa mobu le mongobo le sebopeho sa mobu, tšebeliso ea mocheso oa mobu e lokela ho ba kholo ho feta 12 ° C, 12-30 ° C ke eona e loketseng ka ho fetisisa, mongobo oa mobu o moholo ho feta 40% (mongobo ho letsoho pinch mobu o ka theha sehlopha, bophahamo ba limithara tse 1 bo ka qhalakanngoa ka mor'a ho oela fatše e le tekanyetso).
