Isicelo
Izibulala-zinambuzane ezibanzi. Ama-nematocides anomsebenzi wokufutha angabolisa i-methyl isothiocyanate, i-formaldehyde kanye ne-hydrogen sulfide enhlabathini, futhi abe nomphumela wokubulala i-rhizoma nematode, i-stem nematode kanye ne-heteroderma nematode. Ngaphezu kwalokho, anemiphumela yokubulala izinambuzane, ukubulala amagciwane kanye nokubulala ukhula, ngakho-ke angalapha futhi isikhunta senhlabathi, izinambuzane ezingaphansi komhlaba kanye nokhula lwe-chenopodium, njenge-potato rhizoctonia, izinambuzane ze-soil polypteroptera, ama-kowbeetles, izibungu ze-May scarab njalo njalo. Ukusebenzisa i-98% particulate agent 750 ~ 900g/100m2 sand soil, 900 ~ 1050g/100m2 clay njengokwelashwa kwenhlabathi, ukusabalala noma ukufakwa komsele, i-Chemicalbook ingalawula isifo semifino kanye ne-peanut nematode. I-75% wettable powder 1125g/100m2 ingasetshenziswa ukulawula isifo se-potato root nematode.
I-Soil fumigant, i-methyl thioisothiocyanate nematocide, kanye nokwelapha isikhunta, izinambuzane ezingaphansi komhlaba kanye nokhula, okwaziwa nangokuthi ukuphela okusheshayo. Umkhiqizo ubola enhlabathini ukuze wakhe i-methylaminomethyl dithiocarbamate, futhi wakhe i-methyl isothiocyanate. Ingalawula ngempumelelo ama-nematode kanye nesikhunta senhlabathi, njengebhaktheriya i-cataplexy, amabhaktheriya e-filarial, i-fusarium, njll., futhi ingavimbela nokukhula kokhula oluningi. Inomthelela omuhle wokulawula ku-cotton yellow blight.
Inqubo yokubulala amagciwane
(1) Ngaphambi kokusebenzisa i-Dazomet, hlanza izimpande zesivuno sokugcina, bese ufaka umanyolo oyisisekelo odingekayo esivunweni esilandelayo.
(2) Qinisekisa ukuthi umswakama wenhlabathi ufinyelela cishe ku-50-60% wamandla amanzi asensimini, uma ungahlangabezani nezinga elijwayelekile, ungafaka amanzi ensimini; ezinsukwini ezi-3-5 ngemva kokunisela, sebenzisa umshini ukuze uphendule futhi uphule inhlabathi ukuqinisekisa ukuthi inhlabathi iyangena.
(3) Uma usebenzisa i-Dazomet, izinga lokushisa elifanele lomhlabathi lingu-12-18 ° C, futhi okungenani akufanele libe ngaphansi kuka-6 ° C.
(4) Sebenzisa amagremu angu-25-40 eDazomet ngemitha yesikwele yomhlaba. Phakathi kwazo, ukusetshenziswa kwekhukhamba, upelepele omnandi, igreenhouse kapelepele kungu-20-25kg/mu, ukusetshenziswa kwegreenhouse katamatisi kungu-25-30kg/mu, kanye nokusetshenziswa kwegreenhouse yama-strawberry kungu-15-20kg/mu.
(5) Faka umuthi ngokulinganayo phezu komhlaba, bese usebenzisa i-rotary plow ukuze ulime ngokujikeleza (ukujula kungu-25-30cm), ukuze ukuphakama kwe-Dazomet kuthintane ngokuphelele nesendlalelo sokulima ukuze kufezwe ukusebenza kahle okukhulu. Uma i-root knot nematode ivele kakhulu, ukujula kokulima ngokujikeleza kufanele kube ngu-40cm, futhi umkhawulo ophezulu wokusetshenziswa kwezidakamizwa kufanele usetshenziswe.
(6) Ngemva kokufaka, amanzi afuthwa phezu kobuso ukuze kukhiqizwe igesi yokubulala amagciwane (i-methyl isothiocyanate, i-formaldehyde kanye ne-hydrogen sulfide).
(7) Mboza ifilimu (ukujiya akufanele kube ngaphansi kukasilika ongu-6), bese ucindezela ifilimu ngenhlabathi entsha, ungavumeli igesi yokubulala amagciwane iphume, bese ugcina izinga lokushisa lomhlabathi liyi-10cm ku-20℃, uvale ukubulala amagciwane cishe izinsuku eziyi-15-20 (esimweni sezulu esiphansi, isikhathi sokubulala amagciwane kufanele sandiswe).
(8) Ngemva kokuhlanza amagciwane, vula ifilimu, bese usebenzisa i-rotary plow ukuze uphefumulele inhlabathi, ukhulule amagesi anobuthi asele enhlabathini, ngokuvamile uphefumulele cishe izinsuku ezingu-15 (uma isimo sezulu sibanda futhi simanzi, yandisa isikhathi sokuphefumula, uma isimo sezulu sishisa futhi somile, nciphisa isikhathi sokuphefumula).
(9) Imbewu ingahlwanyelwa ngemva kokubulala amagciwane.
Indlela ye-Dazomet boom
1. I-Dazomet iyisibulali-magciwane sokubulala izinambuzane esibanzi esinobungani nemvelo esisebenza kahle kakhulu, sinobuthi obuphansi futhi asinazo izinsalela.
2. Uma isetshenziswa enhlabathini emanzi, iyabola ibe yi-methyl isothiocyanate enobuthi, i-formaldehyde kanye ne-hydrogen sulfide enhlabathini, futhi isakazeka ngokushesha ezinhlayiyeni zomhlabathi, ibulale ngempumelelo ama-nematode ahlukahlukene, amagciwane, izinambuzane ezingaphansi komhlaba kanye nembewu yokhula ehlumayo enhlabathini, ukuze kufezwe umphumela wokuhlanza inhlabathi.
3. Ukusetshenziswa kuthinteka kakhulu yizinga lokushisa lomhlabathi kanye nomswakama kanye nesakhiwo senhlabathi, ukusetshenziswa kwezinga lokushisa lomhlabathi kufanele kube ngaphezu kuka-12 ° C, 12-30 ° C yikho okufanele kakhulu, umswakama wenhlabathi ungaphezu kuka-40% (umswakama wokuncinza inhlabathi ngesandla ungakha iqembu, ukuphakama kwemitha eli-1 kungahlakazeka ngemva kokuwela phansi njengendinganiso).
