Ukongeza, ine-insecticidal, i-bactericidal kunye nemiphumo ye-herbicidal, ngoko inokuphatha i-fungi yomhlaba, izinambuzane eziphantsi komhlaba kunye nokhula lwe-chenopodium. |
Isicelo
Amachiza okubulala izitshabalalisi. I-nematocides enomsebenzi wokutshisa inokubolisa i-methyl isothiocyanate, i-formaldehyde kunye ne-hydrogen sulfide emhlabeni, kwaye ibe nefuthe lokubulala kwirhizoma nematode, i-stem nematode kunye ne-heteroderma nematode. Ukongezelela, ine-insecticidal, i-bactericidal kunye nemiphumo ye-herbicidal, ngoko inokuphinda iphathe i-fungi yomhlaba, izinambuzane eziphantsi komhlaba kunye nokhula lwe-chenopodium, njenge-potato rhizoctonia, inambuzane ye-polypteroptera yomhlaba, i-kowbeetles, i-May scarab larvae njalo njalo. Ukusebenzisa i-98% ye-particulate agent 750 ~ 900g / 100m2 umhlaba wesanti, i-900 ~ 1050g / 100m2 yodongwe njengonyango lomhlaba, ukusabalalisa okanye ukusetyenziswa komsele, i-Chemicalbook inokulawula isifo semifuno kunye ne-peanut nematode. I-75% yomgubo omanzi 1125g/100m2 ingasetyenziselwa ukulawula isifo seengcambu zeetapile.
I-fumigant yomhlaba, i-methyl thioisothiocyanate nematocide, kunye nokunyanga umngundo, izinambuzane ezitshabalalisayo eziphantsi komhlaba kunye nokhula, nokwaziwa njengokuphela ngokukhawuleza. Imveliso ibolile emhlabeni ukuze yenze i-methylaminomethyl dithiocarbamate, kwaye yenze i-methyl isothiocyanate. Iyakwazi ukulawula ngokufanelekileyo i-nematodes kunye nokungunda komhlaba, njengebhaktiriya ye-cataplexy, ibhaktheriya ye-filarial, i-fusarium, njl., kwaye inokuthintela ukukhula kokhula oluninzi. Inempembelelo entle yokulawula umqhaphu otyheli.
Inkqubo yokubulala iintsholongwane
(1) Ngaphambi kokusebenzisa i-Dazomet, coca iingcambu zesityalo sokugqibela, kwaye usebenzise isichumiso esisisiseko esifunwa sisityalo esilandelayo.
(2) Qinisekisa ukuba ukufuma komhlaba kufikelela malunga ne-50-60% yomthamo wamanzi entsimi, ukuba awuhambisani nomgangatho, unokutofa amanzi ebaleni; Kwiintsuku ezi-3-5 emva kokunkcenkceshela, sebenzisa umatshini ukujika kunye nokwaphula umhlaba ukuqinisekisa ukuba umhlaba uyangena.
(3) Xa usebenzisa iDazomet, ubushushu obufanelekileyo bomhlaba yi-12-18 ° C, kwaye ubuncinci abunakuba ngaphantsi kwe-6 ° C.
(4) Sebenzisa i-25-40g ye-Dazomet kwisikwere semitha yomhlaba. Phakathi kwabo, ukusetyenziswa kwekhukhamba, i-pepper emnandi, i-pepper greenhouse yi-20-25kg / mu, ukusetyenziswa kwe-tomato greenhouse yi-25-30kg / mu, kunye nokusetyenziswa kwe-strawberry greenhouse yi-15-20kg / mu.
(5) Faka iyeza ngokulinganayo phezu komhlaba, uze usebenzise ikhuba elijikelezayo kwi-rotary tillage (ubunzulu buyi-25-30cm), ukwenzela ukuba ukunyuka kweDazomet kudibene ngokupheleleyo nomgca wokulima ukuphumeza ukusebenza okuphezulu. Ukuba i-root knot nematode yenzeke ngokunzulu, ubunzulu be-rotary tillage kufuneka bube yi-40cm, kwaye kusetyenziswe umda ophezulu wokusetyenziswa kweziyobisi.
(6) Emva kokufakwa, amanzi atshizwa phezu komhlaba ukuvelisa igesi yokubulala iintsholongwane (i-methyl isothiocyanate, i-formaldehyde kunye ne-hydrogen sulfide).
(7) Gubungela ifilimu (ubunzima abuyi kuba ngaphantsi kwe-silk ye-6), uze udibanise ifilimu ngomhlaba omtsha, ungavumeli i-gas ye-disinfection iphume, kwaye ugcine ubushushu bomhlaba kwi-10cm kwi-20 ℃, i-disinfection evaliweyo malunga neentsuku ze-15-20 (kwimozulu ephantsi yobushushu, ixesha lokufunxa kufuneka landiswe).
(8) Emva kokubulawa kweentsholongwane, tyhila ifilimu, uze usebenzise ikhuba elijikelezayo ukuze ukhuphe umoya emhlabeni, ukhulule iigesi ezinetyhefu eziseleyo emhlabeni, ngokuqhelekileyo khupha umoya kangangeentsuku ezili-15 (xa imozulu ibanda yaye imanzi, yandisa ixesha lokungenisa umoya, xa imozulu ishushu yaye yomile, nciphisa ixesha lokungenisa umoya).
(9) Imbewu inokuhlwayelwa emva kokubulawa kweentsholongwane.
Inkqubo yeDazomet boom
1. I-Dazomet sisisithinteli sokusingqongileyo esibanzi esibanzi esibanzi sokufunxa iintsholongwane emhlabeni esisebenza ngokufanelekileyo, ubutyhefu obuphantsi kwaye akukho ntsalela.
2. Xa isetyenziswe kumhlaba omanzi, ichithwa kwi-methyl isothiocyanate enetyhefu, i-formaldehyde kunye ne-hydrogen sulfide emhlabeni, kwaye isasazeka ngokukhawuleza kwiincinci zomhlaba, ngokubulala ngokufanelekileyo i-nematodes eyahlukeneyo, i-pathogens, izinambuzane eziphantsi komhlaba kunye nokuhluma kwembewu yokhula emhlabeni, ukuze kufezekiswe umphumo wokucoca umhlaba.
3. isicelo sichatshazelwa kakhulu ngubushushu bomhlaba kunye nokufuma kunye nesakhiwo somhlaba, ukusetyenziswa kobushushu bomhlaba kufuneka kube ngaphezu kwe-12 ° C, i-12-30 ° C yeyona nto ifanelekileyo, ukufuma komhlaba kukhulu kunama-40% (ukufuma kwi-pinch yomhlaba ngesandla kunokwenza iqela, ukuphakama kwemitha eyi-1 kunokusasazwa emva kokuwela phantsi njengomgangatho).
