Faɗin magungunan kashe qwari. Nematocides tare da aikin fumigation na iya lalata methyl isothiocyanate, formaldehyde da hydrogen sulfide a cikin ƙasa, kuma suna da tasirin kashewa akan rhizoma nematode, kara nematode da heteroderma nematode. Bugu da ƙari, yana da tasirin kwari, bactericidal da herbicidal, don haka yana iya magance fungi na ƙasa, kwari na karkashin kasa da weeds chenopodium, irin su dankalin turawa rhizoctonia, ƙasa polypteroptera kwari, kowbeetles, May scarab larvae da sauransu. Yin amfani da 98% particulate wakili 750 ~ 900g / 100m2 yashi ƙasa, 900 ~ 1050g / 100m2 yumbu a matsayin ƙasa jiyya, yada ko mahara aikace-aikace, Chemicalbook iya sarrafa kayan lambu da kuma gyada nematode cuta. 75% wettable foda 1125g/100m2 za a iya amfani da su sarrafa dankalin turawa tushen nematode cuta.
Fumigant na ƙasa, methyl thioisothiocyanate nematocide, da kuma maganin fungi, kwari da ciyawa na ƙarƙashin ƙasa, wanda kuma aka sani da halaka da sauri. Samfurin yana bazuwa a cikin ƙasa don samar da methylaminomethyl dithiocarbamate, kuma ya ƙara samar da methyl isothiocyanate. Yana iya sarrafa nematodes da fungi na ƙasa yadda ya kamata, kamar ƙwayoyin cuta na cataplexy, ƙwayoyin filarial, fusarium, da sauransu, kuma yana iya hana ci gaban ciyawa da yawa. Yana da tasiri mai kyau akan auduga rawaya blight.
Tsarin disinfection
(1) Kafin amfani da Dazomet, tsaftace tushen amfanin gona na ƙarshe, sannan a yi amfani da takin da ake buƙata na gaba.
(2) Tabbatar cewa damshin ƙasa ya kai kusan 50-60% na ƙarfin ruwa na filin, idan bai dace da ma'auni ba, zaku iya allurar ruwa a cikin filin; Kwanaki 3-5 bayan ban ruwa, yi amfani da injin don juyawa da karya ƙasa don tabbatar da ƙarancin ƙasa.
(3) Lokacin amfani da Dazomet, yanayin da ya dace na ƙasa shine 12-18 ° C, kuma mafi ƙarancin ba zai iya zama ƙasa da 6 ° C ba.
(4) Yi amfani da 25-40g na Dazomet kowace murabba'in mita na ƙasar. Daga cikin su, amfani da kokwamba, barkono mai dadi, barkono barkono yana da 20-25kg/mu, amfanin gonar tumatir shine 25-30kg/mu, amfani da greenhouse strawberry shine 15-20kg/mu.
(5) Aiwatar da miyagun ƙwayoyi a ko'ina a saman, sa'an nan kuma amfani da garma rotary don rotary tillage (zurfin shi ne 25-30cm), don haka Dazomet tashi ya kasance cikakke a cikin hulɗa da Layer na noma don cimma iyakar inganci. Idan tushen kullin nematode ya faru da gaske, zurfin noman rotary yakamata ya zama 40cm, kuma yakamata a yi amfani da iyakar iyakar amfani da miyagun ƙwayoyi.
(6) Bayan aikace-aikacen, ana fesa ruwa a saman don samar da iskar gas mai lalata (methyl isothiocyanate, formaldehyde da hydrogen sulfide).
(7) Rufe fim ɗin (kauri ba zai zama ƙasa da siliki 6 ba), sa'an nan kuma haɗa fim ɗin tare da sabon ƙasa, kar a bar iskar gas ɗin disinfection ta zubar, kuma a kiyaye zafin jiki na ƙasa a 10cm a 20 ℃, rufaffiyar disinfection na kimanin kwanaki 15-20 (a cikin ƙananan yanayin zafi, ya kamata a tsawaita lokacin fumigation).
(8) Bayan an kashe shi, sai a bude fim din, sannan a yi amfani da garma rotary don shakar da kasa, a saki iskar gas da ta rage a cikin kasa, yawanci tana shaka har na tsawon kwanaki 15 (idan yanayi ya yi sanyi da jika, sai a tsawaita lokacin iska, lokacin da yanayi ya yi zafi da bushewa, a rage lokacin iska).
(9) Za a iya shuka iri bayan an kashe shi.
Kayan aikin Dazomet boom
1. Dazomet ne mai m muhalli m-bakan m ƙasa fumigation disinfectant tare da babban inganci, low toxicity kuma babu saura.
2. Lokacin amfani da ƙasa rigar, an bazu zuwa cikin methyl isothiocyanate mai guba, formaldehyde da hydrogen sulfide a cikin ƙasa, kuma cikin sauri ya bazu zuwa ga barbashi na ƙasa, yadda ya kamata ya kashe nau'ikan nematodes, pathogens, kwari na ƙasa da germination iri iri a cikin ƙasa, don cimma sakamako na tsaftace ƙasa.
3. aikace-aikacen yana da matukar tasiri da zafin jiki da zafi da tsarin ƙasa, yin amfani da zafin jiki na ƙasa ya kamata ya fi girma fiye da 12 ° C, 12-30 ° C shine mafi dacewa, zafi na ƙasa ya fi 40% (danshi zuwa hannun tsunkule ƙasa zai iya samar da ƙungiya, tsayin mita 1 za a iya tarwatsa bayan fadowa ƙasa a matsayin misali).
