Kuphatikiza apo, ali ndi mphamvu yopha tizilombo, yopha mabakiteriya komanso yopha udzu, kotero amathanso kuchiza bowa wa m'nthaka, tizilombo tomwe timakhala pansi pa nthaka ndi udzu wa chenopodium. |
Kugwiritsa ntchito
Mankhwala ophera tizilombo okhala ndi ma spread spectrum. Mankhwala ophera tizilombo okhala ndi ntchito yofukiza amatha kuwononga methyl isothiocyanate, formaldehyde ndi hydrogen sulfide m'nthaka, ndipo amatha kupha rhizoma nematode, stem nematode ndi heteroderma nematode. Kuphatikiza apo, ali ndi mphamvu yopha tizilombo, mabakiteriya komanso mankhwala ophera udzu, kotero amathanso kuchiza bowa wa m'nthaka, tizilombo tomwe timakhala pansi pa nthaka ndi udzu wa chenopodium, monga mbatata rhizoctonia, tizilombo ta polypteroptera m'nthaka, kowbeetles, mphutsi za May scarab ndi zina zotero. Pogwiritsa ntchito 98% ya tinthu tating'onoting'ono 750 ~ 900g/100m2, dongo la 900 ~ 1050g/100m2 ngati mankhwala a nthaka, kufalikira kapena kugwiritsa ntchito ngalande, Chemicalbook imatha kuwongolera matenda a masamba ndi mtedza. 75% ufa wonyowa 1125g/100m2 ungagwiritsidwe ntchito kuwongolera matenda a mbatata root nematode.
Chofukiza nthaka, methyl thioisothiocyanate nematocide, komanso chochiza bowa, tizilombo tomwe timakhala pansi pa nthaka ndi udzu, zomwe zimadziwikanso kuti kutha msanga. Chogulitsacho chimawola mu nthaka kuti chipange methylaminomethyl dithiocarbamate, komanso kuti chipange methyl isothiocyanate. Chimatha kuwongolera bwino nematodes ndi bowa wa nthaka, monga mabakiteriya a cataplexy, mabakiteriya a filarial, fusarium, ndi zina zotero, ndipo chingalepheretsenso kukula kwa namsongole wambiri. Chimalamulira bwino bowa wachikasu wa thonje.
Njira yochotsera matenda
(1) Musanagwiritse ntchito Dazomet, yeretsani mizu ya mbewu yomaliza, ndipo ikani feteleza wofunikira pa mbewu yotsatira.
(2) Onetsetsani kuti chinyezi cha nthaka chafika pafupifupi 50-60% ya mphamvu ya madzi a m'munda, ngati sichikukwaniritsa muyezo, mutha kulowetsa madzi m'munda; Patatha masiku 3-5 mutathirira, gwiritsani ntchito makinawo kutembenuza ndikuswa nthaka kuti muwonetsetse kuti nthakayo ilowa madzi.
(3) Mukagwiritsa ntchito Dazomet, kutentha koyenera kwa nthaka ndi 12-18 ° C, ndipo kutentha kocheperako sikuyenera kuchepera 6 ° C.
(4) Gwiritsani ntchito 25-40g ya Dazomet pa mita imodzi ya malo. Pakati pa izi, kugwiritsa ntchito nkhaka, tsabola wotsekemera, tsabola wowonjezera kutentha ndi 20-25kg/mu, kugwiritsa ntchito phwetekere wowonjezera kutentha ndi 25-30kg/mu, ndipo kugwiritsa ntchito sitiroberi wowonjezera kutentha ndi 15-20kg/mu.
(5) Ikani mankhwalawo mofanana pamwamba, kenako gwiritsani ntchito pulawo yozungulira polima mozungulira (kuya kwake ndi 25-30cm), kuti Dazomet ikwere bwino kuti igwirizane ndi gawo lolima kuti igwire bwino ntchito. Ngati mizu ya nematode yapezeka kwambiri, kuya kwa malo olima mozungulira kuyenera kukhala 40cm, ndipo malire apamwamba ogwiritsira ntchito mankhwala ayenera kugwiritsidwa ntchito.
(6) Pambuyo popaka, madzi amathiridwa pamwamba kuti apange mpweya wophera tizilombo toyambitsa matenda (methyl isothiocyanate, formaldehyde ndi hydrogen sulfide).
(7) Phimbani filimuyi (makulidwe ake asapitirire 6 silika), kenako phatikizani filimuyi ndi dothi latsopano, musalole mpweya wothira majeremusi kutuluka, ndipo sungani kutentha kwa nthaka pa 10cm pa 20℃, tsekani mankhwala othira majeremusi kwa masiku pafupifupi 15-20 (ngati nyengo ili yotentha kwambiri, nthawi yothira majeremusi iyenera kuwonjezeredwa).
(8) Mukamaliza kuyeretsa, tsegulani filimuyo, ndipo gwiritsani ntchito pulawo lozungulira kuti mulowetse mpweya m'nthaka, tulutsani mpweya woipa womwe watsala m'nthaka, nthawi zambiri perekani mpweya kwa masiku pafupifupi 15 (nyengo ikazizira komanso yonyowa, onjezerani nthawi yopumira, nyengo ikatentha komanso youma, chepetsani nthawi yopumira).
(9) Mbewu zitha kubzalidwa mutazichotsa mu mankhwala ophera tizilombo toyambitsa matenda.
Njira ya Dazomet boom
1. Dazomet ndi mankhwala ophera tizilombo toyambitsa matenda omwe amawononga nthaka, omwe ndi abwino kwambiri, alibe poizoni wambiri komanso alibe zotsalira.
2. Ikagwiritsidwa ntchito pa nthaka yonyowa, imawola kukhala methyl isothiocyanate, formaldehyde ndi hydrogen sulfide yoopsa m'nthaka, ndipo imafalikira mofulumira ku tinthu ta nthaka, kupha bwino mitundu yosiyanasiyana ya nematode, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda pansi pa nthaka ndi mbewu za udzu zomwe zimamera m'nthaka, kuti zikwaniritse zotsatira zoyeretsa nthaka.
3. Kugwiritsa ntchito kumakhudzidwa kwambiri ndi kutentha kwa nthaka ndi chinyezi komanso kapangidwe ka nthaka, kugwiritsa ntchito kutentha kwa nthaka kuyenera kukhala kopitilira 12 ° C, 12-30 ° C ndiye koyenera kwambiri, chinyezi cha nthaka ndi choposa 40% (chinyezi chomwe chingagwiritsidwe ntchito pobaya dothi ndi manja chingapange gulu, kutalika kwa mita imodzi kumatha kufalikira mutagwa pansi monga muyezo).
