Kugwiritsa ntchito
Mankhwala opha tizilombo. Ma nematocides okhala ndi fumigation function amatha kuwola methyl isothiocyanate, formaldehyde ndi hydrogen sulfide m'nthaka, ndipo amatha kupha rhizoma nematode, stem nematode ndi heteroderma nematode. Kuphatikiza apo, imakhala ndi mankhwala ophera tizilombo, bactericidal ndi herbicidal, kotero imatha kuchitiranso bowa, tizirombo tating'onoting'ono ndi namsongole wa chenopodium, monga mbatata rhizoctonia, tizilombo ta polypteroptera, kowbeetles, mphutsi za May scarab ndi zina zotero. Pogwiritsa ntchito 98% particulate agent 750 ~ 900g/100m2 dothi lamchenga, 900 ~ 1050g/100m2 dongo monga chithandizo cha dothi, kufalikira kapena kugwiritsa ntchito ngalande, Chemicalbook imatha kuthana ndi matenda a masamba ndi mtedza wa nematode. 75% ufa wonyowa 1125g/100m2 angagwiritsidwe ntchito pothana ndi matenda a nematode muzu wa mbatata.
Dothi fumigant, methyl thioisothiocyanate nematocide, komanso kuchiza mafangasi, tizirombo pansi pa nthaka ndi namsongole, zomwe zimadziwikanso kuti kutha msanga. Mankhwalawa amawola m'nthaka kuti apange methylaminomethyl dithiocarbamate, ndikupitilira kupanga methyl isothiocyanate. Imatha kuwononga bwino ma nematode ndi mafangasi a m'nthaka, monga mabakiteriya a cataplexy, mabakiteriya a filarial, fusarium, ndi zina zotero, ndipo imathanso kulepheretsa kukula kwa udzu wambiri. Imakhala ndi mphamvu yowongolera pa thonje chikasu choipitsa.
Njira yopha tizilombo toyambitsa matenda
(1) Musanagwiritse ntchito Dazomet, yeretsani mizu ya mbewu yomaliza, ndikuthira feteleza wofunikira pa mbewu yotsatira.
(2) Onetsetsani kuti chinyezi cha nthaka chikufikira pafupifupi 50-60% ya mphamvu ya madzi a m’munda, ngati sichikukwanira, mukhoza kubaya madzi m’munda; Pakatha masiku 3-5 mutatha kuthirira, gwiritsani ntchito makinawo kuti mutembenuzire ndikuphwanya nthaka kuti mutsimikize kuti nthakayo imalowa bwino.
(3) Mukamagwiritsa ntchito Dazomet, kutentha koyenera kwa nthaka ndi 12-18 ° C, ndipo osachepera sangakhale osachepera 6 ° C.
(4) Gwiritsani ntchito 25-40g ya Dazomet pa lalikulu mita imodzi. Pakati pawo, kugwiritsa ntchito nkhaka, tsabola wokoma, wowonjezera kutentha kwa tsabola ndi 20-25kg/ mu, kugwiritsa ntchito tomato wowonjezera kutentha ndi 25-30kg/ mu, ndi kugwiritsa ntchito sitiroberi wowonjezera kutentha ndi 15-20kg/ mu.
(5) Gwiritsani ntchito mankhwalawo mofanana pamtunda, ndiyeno mugwiritseni ntchito pulawo yozungulira yozungulira (kuya ndi 25-30cm), kotero kuti kukwera kwa Dazomet kumagwirizana kwambiri ndi kulima kuti mukwaniritse bwino kwambiri. Ngati muzu wa mfundo za nematode uchitika mozama, kulima mozungulira kuyenera kukhala 40cm, ndipo kugwiritsa ntchito mankhwala kukuyenera kuchepetsedwa.
(6) Akapaka, madzi amawathira pamwamba kuti atulutse mpweya wopha tizilombo toyambitsa matenda (methyl isothiocyanate, formaldehyde ndi hydrogen sulfide).
(7) Phimbani filimuyo (makulidwe sadzakhala osachepera 6 silika), ndiye yaying'ono filimuyo ndi nthaka yatsopano, musalole kuti disinfection mpweya kutayikira kunja, ndi kusunga kutentha kwa nthaka pa 10cm pa 20 ℃, kutsekedwa disinfection kwa masiku 15-20 (mu kutentha otsika nyengo, fumigation nthawi ayenera anawonjezera).
(8) Pambuyo popha tizilombo toyambitsa matenda, vumbulutsani filimuyo, ndipo gwiritsani ntchito pulawo yozungulira kutulutsa mpweya m’nthaka, kutulutsa mpweya wapoizoni womwe watsala m’nthaka, nthawi zambiri mpweya umakhala wokwanira kwa masiku 15 (pamene nyengo ili yozizira komanso yonyowa, onjezerani nthawi yopuma mpweya, nyengo ikatentha ndi youma, chepetsani mpweya wa mpweya).
(9) Mbewu zingabzalidwe pambuyo popha tizilombo toyambitsa matenda.
Njira ya Dazomet boom
1. Dazomet ndi wochezeka chilengedwe yotakata sipekitiramu mabuku fumigation mankhwala ndi mkulu dzuwa, otsika kawopsedwe ndipo palibe zotsalira.
2. Akagwiritsidwa ntchito pa nthaka yonyowa, amawonongeka kukhala poizoni wa methyl isothiocyanate, formaldehyde ndi hydrogen sulfide m'nthaka, ndipo amafalikira mofulumira ku tinthu tating'onoting'ono, kupha tizilombo toyambitsa matenda osiyanasiyana, tizilombo toyambitsa matenda, tizilombo toyambitsa matenda ndi kumera mbewu za udzu m'nthaka, kuti akwaniritse zotsatira za kuyeretsa nthaka.
3. ntchito imakhudzidwa kwambiri ndi kutentha kwa nthaka ndi chinyezi ndi dongosolo la nthaka, kugwiritsa ntchito kutentha kwa nthaka kuyenera kukhala kwakukulu kuposa 12 ° C, 12-30 ° C ndikoyenera kwambiri, chinyezi cha nthaka ndi chachikulu kuposa 40% (chinyezi ku dzanja kutsina nthaka akhoza kupanga gulu, 1 mita kutalika akhoza omwazika pambuyo kugwa pansi monga muyezo).
