Chefo e bolaeang likokoanyana e pharaletseng. Li-nematocide tse nang le ts'ebetso ea ho tsubella li ka bolisa methyl isothiocyanate, formaldehyde le hydrogen sulfide mobung, 'me li na le phello ea ho bolaea rhizoma nematode, stem nematode le heteroderma nematode. Ho phaella moo, e na le litlamorao tsa ho bolaea likokoanyana, ho bolaea libaktheria le ho bolaea litlama, kahoo e ka boela ea phekola li-fungus tsa mobu, likokoanyana tse ka tlas'a lefatše le mofoka oa chenopodium, joalo ka rhizoctonia ea litapole, likokoanyana tsa polypteroptera ea mobu, li-kowbeetles, li-larvae tsa May scarab le tse ling. Ho sebelisoa 98% ea mokelikeli oa likaroloana 750 ~ 900g/100m2 mobu oa lehlabathe, 900 ~ 1050g/100m2 letsopa e le kalafo ea mobu, ho jala kapa ho sebelisa foro, Chemicalbook e ka laola lefu la meroho le peanut nematode. 75% phofo e metsi 1125g/100m2 e ka sebelisoa ho laola lefu la litapole root nematode.
Sebolaya-mobu, methyl thioisothiocyanate nematocide, hape le ho phekola li-fungus, likokoanyana tse ka tlas'a lefatše le mofoka, tse tsejoang hape e le ho fela ka potlako. Sehlahisoa se bolisoa mobung ho etsa methylaminomethyl dithiocarbamate, le ho feta moo ho etsa methyl isothiocyanate. E ka laola li-nematode le li-fungus tsa mobu ka katleho, joalo ka libaktheria tsa cataplexy, libaktheria tsa filarial, fusarium, jj., 'me e ka boela ea thibela kholo ea mofoka o mongata. E na le phello e ntle ea taolo holim'a blight ea k'hothone e mosehla.
Mokhoa oa ho bolaea likokoana-hloko
(1) Pele o sebedisa Dazomet, hlwekisa metso ya sejalo sa ho qetela, mme o tshele manyolo a motheo a hlokahalang bakeng sa sejalo se latelang.
(2) Netefatsa hore mongobo mobung o fihla ho hoo e ka bang 50-60% ea matla a metsi a tšimo, haeba o sa fihlelle maemo a tloaelehileng, o ka kenya metsi tšimong; Matsatsi a 3-5 kamora ho nosetsa, sebelisa mochini ho reteleha le ho roba mobu ho netefatsa hore mobu o kena ka metsing.
(3) Ha o sebedisa Dazomet, mocheso o loketseng wa mobu ke 12-18 ° C, mme bonyane ha bo a lokela ho ba ka tlase ho 6 ° C.
(4) Sebelisa 25-40g ea Dazomet ka mithara e le 'ngoe ea mobu. 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, 'me tšebeliso ea sethopo sa fragola ke 15-20kg/mu.
(5) Tlotsa moriana ka ho lekana holim'a metsi, ebe o sebedisa mohoma o potolohang bakeng sa ho lema ka ho potoloha (botebo ke 25-30cm), e le hore ho phahama ha Dazomet ho kopane ka botlalo le lera la ho lema ho fihlela katleho e kgolo. Haeba nematode ya leqhubu la motso e hlaha ka botebo, botebo ba ho lema ka ho potoloha e lokela ho ba 40cm, mme moedi o ka hodimo wa tshebediso ya meriana o lokela ho sebediswa.
(6) Kamora ho e sebedisa, metsi a fafatswa hodima metsi ho hlahisa kgase ya ho bolaya dikokwana-hloko (methyl isothiocyanate, formaldehyde le hydrogen sulfide).
(7) Kwahela filimi (botenya ha boa lokela ho ba ka tlase ho silika e 6), ebe o kopanya filimi ka mobu o mocha, o se ke wa dumella kgase ya dibolaya-ditwatsi ho dutla, mme o boloke mocheso wa mobu ho 10cm ho 20℃, o kwale dibolaya-ditwatsi matsatsi a ka bang 15-20 (maemong a lehodimo a mocheso o tlase, nako ya ho ntsha ditwatsi e lokela ho atoloswa).
(8) Kamora ho hloekisa dikokwana-hloko, bula filimi, 'me u sebelise mohoma o potolohang ho kenya moea mobung, u lokolle likhase tse chefo tse setseng mobung, hangata u kenya moea matsatsi a ka bang 15 (ha boemo ba leholimo bo bata ebile bo le metsi, eketsa nako ea ho kenya moea, ha boemo ba leholimo bo chesa ebile bo omme, fokotsa nako ea ho kenya moea).
(9) Peo e ka jaloa ka mora ho bolawa dikokwana-hloko.
Mokhoa oa ho phatloha ha Dazomet
1. Dazomet ke sebolaya-dikokwana-hloko se sireletsang tikoloho se akaretsang mobu o ntshang dikokwana-hloko ka bongata, se nang le bokgoni bo phahameng, chefo e tlase mme ha se na masalla.
2. Ha e sebelisoa mobung o metsi, e bola hore e be methyl isothiocyanate e chefo, formaldehyde le hydrogen sulfide mobung, 'me e namela ka potlako likarolong tsa mobu, e bolaea li-nematode tse fapaneng, likokoana-hloko, likokoanyana tse ka tlas'a lefatše le peo ea mofoka e melang mobung, e le ho fihlela phello ea ho hloekisa mobu.
3. tshebediso e angwa haholo ke mocheso wa mobu le mongobo le sebopeho sa mobu, tshebediso ya mocheso wa mobu e lokela ho ba ho feta 12 ° C, 12-30 ° C ke yona e loketseng ka ho fetisisa, mongobo wa mobu o moholo ho feta 40% (mongobo wa ho phunya mobu ka letsoho o ka bopa sehlopha, bolelele ba mithara e le 1 bo ka hasana ka mora ho wela fatshe jwalo ka tekanyetso).
