Ngaphezu kwalokho, inemiphumela ye-insecticidal, bactericidal kanye ne-herbicidal, ngakho-ke ingakwazi futhi ukuphatha isikhunta senhlabathi, izinambuzane ezingaphansi komhlaba kanye nokhula lwe-chenopodium. |
Isicelo
Izibulala-zinambuzane ezibanzi. Ama-nematocides anomsebenzi wokufutha angabola i-methyl isothiocyanate, i-formaldehyde ne-hydrogen sulfide enhlabathini, futhi abe nomthelela obulalayo ku-rhizoma nematode, i-stem nematode ne-heteroderma nematode. Ngaphezu kwalokho, inemiphumela ye-insecticidal, bactericidal kanye ne-herbicidal, ngakho-ke ingakwazi futhi ukuphatha isikhunta senhlabathi, izinambuzane ezingaphansi komhlaba kanye nokhula lwe-chenopodium, njenge-potato rhizoctonia, izinambuzane ze-polypteroptera, i-kowbeetles, izibungu ze-May scarab nokunye. Isebenzisa u-98% wezinhlayiyana ezingama-750 ~ 900g/100m2 inhlabathi yesihlabathi, ubumba oluwu-900 ~ 1050g/100m2 njengokwelashwa kwenhlabathi, ukusabalalisa noma ukufaka umsele, i-Chemicalbook ingalawula isifo semifino ne-peanut nematode. 75% impushana emanzi 1125g/100m2 ingasetshenziswa ukulawula isifo se-nematode yezimpande.
I-soil fumigant, i-methyl thioisothiocyanate nematocide, kanye nokwelapha isikhunta, izinambuzane ezingaphansi komhlaba kanye nokhula, okwaziwa nangokuthi ukushabalala okusheshayo. Umkhiqizo ubola enhlabathini ukuze wenze i-methylaminomethyl dithiocarbamate, bese wenza i-methyl isothiocyanate. Ingakwazi ukulawula ngempumelelo ama-nematodes kanye nesikhunta senhlabathi, njenge-cataplexy bacteria, i-filarial bacteria, i-fusarium, njll., futhi ingavimbela ukukhula kokhula oluningi. Inomphumela omuhle wokulawula ukotini ophuzi.
Inqubo yokubulala amagciwane
(1) Ngaphambi kokusebenzisa i-Dazomet, hlanza izimpande zesitshalo sokugcina, bese usebenzisa umanyolo oyisisekelo odingwa yisilimo esilandelayo.
(2) Qinisekisa ukuthi umswakama womhlabathi ufinyelela cishe ku-50-60% womthamo wamanzi asensimini, uma ungafinyeleli izinga, ungajova amanzi ensimini; Ezinsukwini ezi-3-5 emva kokunisela, sebenzisa umshini ukuze uphendule futhi uphule inhlabathi ukuze uqinisekise ukungena kwenhlabathi.
(3) Uma usebenzisa i-Dazomet, izinga lokushisa elifanele lomhlabathi ngu-12-18 ° C, futhi ubuncane abukwazi ukuba ngaphansi kuka-6 ° C.
(4) Sebenzisa u-25-40g we-Dazomet ngemitha-skwele ngayinye yomhlaba. Phakathi kwazo, ukusetshenziswa kwekhukhamba, i-sweet pepper, i-pepper greenhouse yi-20-25kg / mu, ukusetshenziswa kwe-tomato greenhouse yi-25-30kg / mu, kanti ukusetshenziswa kwe-strawberry greenhouse yi-15-20kg / mu.
(5) Gcoba umuthi ngokulinganayo ebusweni, bese usebenzisa igeja elijikelezayo ukuze ulimale (ukujula kungama-25-30cm), ukuze ukuphakama kweDazomet kuhlangane ngokugcwele nongqimba lokulima ukuze kuzuzwe ukusebenza kahle okukhulu. Uma i-root knot nematode yenzeka kakhulu, ukujula kwe-rotary tillage kufanele kube ngu-40cm, futhi umkhawulo ophezulu wokusetshenziswa kwezidakamizwa kufanele usetshenziswe.
(6) Ngemva kokufakwa, amanzi afuthwa phezulu ukuze kukhiqizwe igesi yokubulala amagciwane (i-methyl isothiocyanate, i-formaldehyde ne-hydrogen sulfide).
(7) Vala ifilimu (ubukhulu akumele bube ngaphansi kuka-6 kasilika), bese uhlanganisa ifilimu ngenhlabathi entsha, ungavumeli igesi ye-disinfection iphume, futhi ugcine izinga lokushisa lomhlabathi ku-10cm ku-20 ℃, ukukhishwa kwe-disinfection kuvaliwe cishe izinsuku ezingu-15-20 (esimo sezulu esishisayo, isikhathi sokufuthwa kufanele sinwetshwe).
(8) Ngemva kokubulala amagciwane, vula ifilimu, futhi usebenzise igeja elijikelezayo ukuze ukhiphe umoya enhlabathini, ukhiphe amagesi anobuthi asele enhlabathini, ngokuvamile khipha umoya izinsuku ezingaba ngu-15 (lapho isimo sezulu sibanda futhi simanzi, nweba isikhathi sokungenisa umoya, lapho isimo sezulu sishisa futhi somile, nciphisa isikhathi sokungenisa umoya).
(9) Imbewu ingahlwanyelwa ngemva kokubulala amagciwane.
Indlela ye-Dazomet boom
1. I-Dazomet iyisibulala-magciwane esivumelana nemvelo esibanzi esibanzi esihlanganisa umhlabathi esikhipha amagciwane esisebenza kahle kakhulu, esinobuthi obuphansi futhi esingenazinsalela.
2. Uma isetshenziswa enhlabathini emanzi, ichithwa ibe yi-methyl isothiocyanate enobuthi, i-formaldehyde ne-hydrogen sulfide enhlabathini, futhi isakazeka ngokushesha ezinhlayiyeni zenhlabathi, ibulale ngokuphumelelayo ama-nematode ahlukahlukene, amagciwane, izinambuzane ezingaphansi komhlaba kanye nokuhluma kwembewu yokhula emhlabathini, ukuze kuzuzwe umphumela wokuhlanza inhlabathi.
3. isicelo sithinteka kakhulu ekushiseni kwenhlabathi kanye nomswakama kanye nesakhiwo senhlabathi, ukusetshenziswa kokushisa kwenhlabathi kufanele kube kukhulu kune-12 ° C, i-12-30 ° C iyona efaneleka kakhulu, umswakama wenhlabathi ungaphezu kuka-40% (umswakama owenziwe ngesandla phusha umhlabathi ungakha iqembu, ukuphakama kwemitha elingu-1 kungahlakazeka ngemva kokuwela phansi njengendinganiso).
