Ukongeza, inefuthe lokubulala izinambuzane, ukubulala iintsholongwane kunye nokubulala ukhula, ngoko ke inokunyanga iifungi zomhlaba, izinambuzane ezingaphantsi komhlaba kunye nokhula lwe-chenopodium. |
Isicelo
Izibulali-zinambuzane ezibanzi. Izibulali-zinambuzane ezisebenza nge-fumigation zinokubolisa i-methyl isothiocyanate, i-formaldehyde kunye ne-hydrogen sulfide emhlabeni, kwaye zibe nefuthe lokubulala kwi-rhizoma nematode, i-stem nematode kunye ne-heteroderma nematode. Ukongeza, inefuthe lokubulala izinambuzane, ukubulala iintsholongwane kunye nokubulala ukhula, ngoko ke inokunyanga iifungi zomhlaba, izinambuzane ezingaphantsi komhlaba kunye nokhula lwe-chenopodium, njenge-potato rhizoctonia, izinambuzane ze-polypteroptera zomhlaba, ii-kowbeetles, ii-May scarab larvae njalo njalo. Ukusebenzisa i-98% ye-particulate agent 750 ~ 900g/100m2 sand ground, 900 ~ 1050g/100m2 dongo njengonyango lomhlaba, ukusasazeka okanye ukusetyenziswa komsele, i-Chemicalbook inokulawula isifo se-vegetable nematode se-peanut. I-75% ye-wettable powder 1125g/100m2 ingasetyenziselwa ukulawula isifo se-potato root nematode.
I-Soil fumigant, i-methyl thioisothiocyanate nematocide, kunye nokunyanga iifungi, izinambuzane ezingaphantsi komhlaba kunye nokhula, okwaziwa ngokuba kukuphela ngokukhawuleza. Imveliso iyabola emhlabeni ukuze yenze i-methylaminomethyl dithiocarbamate, kwaye ngakumbi yenze i-methyl isothiocyanate. Ingalawula ngokufanelekileyo ii-nematodes kunye neefungi zomhlaba, ezifana neebhaktiriya ze-cataplexy, iibhaktiriya ze-filarial, i-fusarium, njl.njl., kwaye inokuthintela ukukhula kokhula oluninzi. Inempembelelo entle yokulawula kwi-cotton yellow blight.
Inkqubo yokubulala iintsholongwane
(1) Ngaphambi kokusebenzisa iDazomet, coca iingcambu zesityalo sokugqibela, uze ufake isichumiso esisisiseko esifunekayo kwisityalo esilandelayo.
(2) Qinisekisa ukuba umxholo womswakama womhlaba ufikelela malunga nama-50-60% womthamo wamanzi entsimi, ukuba awufikeleli umgangatho, ungafaka amanzi entsimini; kwiintsuku ezi-3-5 emva kokunkcenkceshela, sebenzisa umatshini ukujika nokuqhekeza umhlaba ukuqinisekisa ukuba umhlaba ungena.
(3) Xa usebenzisa iDazomet, ubushushu obufanelekileyo bomhlaba yi-12-18 ° C, kwaye ubuncinci abunakuba ngaphantsi kwe-6 ° C.
(4) Sebenzisa i-25-40g yeDazomet ngemitha yesikwere nganye yomhlaba. Phakathi kwazo, ukusetyenziswa kwekhukhamba, ipepile emnandi, ipepile eluhlaza yi-20-25kg/mu, ukusetyenziswa kwegreenhouse yetumato yi-25-30kg/mu, kwaye ukusetyenziswa kwegreenhouse yestrawberry yi-15-20kg/mu.
(5) Faka iyeza ngokulinganayo phezu komhlaba, uze usebenzise i-rotary plow xa ulima ngokujikeleza (ubunzulu buyi-25-30cm), ukuze ukunyuka kweDazomet kudibane ngokupheleleyo nomaleko wokulima ukuze kufezekiswe ukusebenza okuphezulu. Ukuba i-root knot nematode yenzeka kakhulu, ubunzulu bokulima ngokujikeleza bufanele bube yi-40cm, kwaye umda ophezulu wokusetyenziswa kweziyobisi kufuneka usetyenziswe.
(6) Emva kokusetyenziswa, amanzi atshizwa phezu komhlaba ukuze kuveliswe igesi yokubulala iintsholongwane (i-methyl isothiocyanate, i-formaldehyde kunye ne-hydrogen sulfide).
(7) Gquma ifilimu (ubude bayo abuyi kuba ngaphantsi kwe-6 silika), uze uyigqume ifilimu ngomhlaba omtsha, ungavumeli igesi yokubulala iintsholongwane iphume, kwaye ugcine ubushushu bomhlaba bukwi-10cm kwi-20℃, uvale ukubulala iintsholongwane kangangeentsuku ezili-15-20 (kwimozulu eshushu ephantsi, ixesha lokufutha kufuneka landiswe).
(8) Emva kokubulala iintsholongwane, vula ifilimu, uze usebenzise i-rotary plow ukuze uphefumle umhlaba, ukhuphe iigesi ezinobuthi eziseleyo emhlabeni, ngokuqhelekileyo phefumla kangangeentsuku ezili-15 (xa imozulu ibanda kwaye imanzi, yandisa ixesha lokukhupha umoya, xa imozulu ishushu kwaye yomile, nciphisa ixesha lokukhupha umoya).
(9) Imbewu ingahlwayelwa emva kokubulala iintsholongwane.
Indlela yokuqhambuka kweDazomet
1. I-Dazomet sisibulali-ntsholongwane somhlaba esibanzi nesinobuhlobo nokusingqongileyo esisebenza kakuhle, sinobuthi obuphantsi kwaye asinantsalela.
2. Xa isetyenziswa kumhlaba omanzi, iyabola ibe yi-methyl isothiocyanate enetyhefu, i-formaldehyde kunye ne-hydrogen sulfide emhlabeni, kwaye isasazeka ngokukhawuleza ukuya kumasuntswana omhlaba, ibulala ngempumelelo ii-nematodes ezahlukeneyo, iintsholongwane, izinambuzane ezingaphantsi komhlaba kunye nembewu yokhula ehlumayo emhlabeni, ukuze kufezekiswe isiphumo sokucoca umhlaba.
3. ukusetyenziswa kwayo kuchaphazeleka kakhulu bubushushu bomhlaba kunye nokufuma kunye nolwakhiwo lomhlaba, ukusetyenziswa kobushushu bomhlaba kufuneka kube ngaphezu kwe-12 ° C, i-12-30 ° C yeyona ifanelekileyo, ukufuma komhlaba kungaphezulu kwe-40% (ukufuma komhlaba onokuthi ucinezelwe ngesandla ungenza iqela, ukuphakama kwe-1 mitha kungasasazeka emva kokuwa emhlabeni njengomgangatho).
