Meloidogyne incognita ndi tizilombo tambiri paulimi, zomwe ndi zovulaza komanso zovuta kuzilamulira.Ndiye, kodi Meloidogyne incognita iyenera kuyendetsedwa bwanji?
Zifukwa zovuta kuwongolera Meloidogyne incognita:
1. Kachilomboka ndi kakang'ono ndipo kamakhala ndi zobisika zamphamvu
Meloidogyne incognita ndi mtundu wa tizilombo toyambitsa matenda tokhala ndi dothi tokhala ndi munthu ting'onoting'ono, titha kuukira mwamphamvu, tizilombo toyambitsa matenda pa mbewu zambiri, udzu, ndi zina;Liwiro loswana limakhala lofulumira, ndipo kuchuluka kwa tizilombo kumakhala kosavuta kudziunjikira mochuluka.
2. Kuwukira muzu, zovuta kuzindikira
Chomera chikawonetsa zizindikiro, mizu yalowa ndi nematode, ndikuwononga mbewuyo.Chomeracho chimachita chimodzimodzi ndi matenda obwera m'nthaka monga bacterial wilt, ndipo chimasokeretsedwa mosavuta ndi mawonekedwe owonekera.
3. Kusinthasintha kwamphamvu kwa chilengedwe
Nthawi zambiri imagwira ntchito m'nthaka yozungulira 15-30cm, kufika kuya kwa 1.5 metres.Itha kupatsira makamu angapo ndipo imatha kukhala ndi moyo kwa zaka 3 ngakhale palibe.
4. Njira zovuta kuchotsa
Pali ma Pathogen ambiri opatsirana a Meloidogyne incognita.Zida zaulimi zoipitsidwa, mbande zokhala ndi mphutsi, ndi dothi lonyamulidwa ndi nsapato pakugwira ntchito zonse zakhala mkhalapakati wa kufala kwa Meloidogyne incognita.
Njira zopewera ndi kuwongolera:
1. Kusankha mitundu ya mbewu
Tiyenera kusankha mitundu kapena rootstocks kugonjetsedwa ndi Meloidogyne incognita, ndi kusankha masamba mitundu kugonjetsedwa ndi matenda kapena matenda, kuti tithe kwambiri kuchepetsa kuvulaza kwa matenda osiyanasiyana.
2. Kubzala mbande m'nthaka yopanda matenda
Pokulitsa mbande, tiyenera kusankha dothi lopanda matenda a Meloidogyne incognita pokulitsa mbande.Nthaka yokhala ndi matenda a Meloidogyne incognita iyenera kutetezedwa ndi tizilombo tisanakwere mbande.Tiyenera kuonetsetsa kuti mbande zilibe matenda.Ndi njira iyi yokha yomwe tingachepetsere kuchuluka kwa matenda akakula.
3. Kulima nthaka mozama ndi kasinthasintha wa mbeu
Nthawi zambiri, ngati tikumba mozama m'nthaka, timafunika kupitirira 25 centimita kapena kupitilira apo kuti tibweretse nematodes mu nthaka yakuya pamwamba.Panthawiyi, nthaka yapansi sidzangokhala yotayirira, komanso imachepetsanso madzi pambuyo poyang'aniridwa ndi dzuwa, zomwe sizingathandize kuti nematode ikhale ndi moyo.
4. Kutentha kwakukulu kwa wowonjezera kutentha, mankhwala a nthaka
Ngati ndi Meloidogyne incognita mu wowonjezera kutentha, tikhoza kugwiritsa ntchito kutentha kwambiri m'chilimwe kupha nematodes ambiri.Nthawi yomweyo, titha kuwola zotsalira za zomera zomwe Meloidogyne incognita amadalira kuti apulumuke m'nthaka.
Komanso, pamene nthaka ndi mchenga, tiyenera kusintha nthaka chaka ndi chaka, amene angathenso bwino kuchepetsa kuwonongeka kwa Meloidogyne incognita.
5. Kusamalira munda
Titha kuthira manyowa ovunda m'munda ndikuwonjezera feteleza wa phosphorous ndi potaziyamu, zomwe zingapangitse kuti zomera zisawonongeke.Tiyenera kukumbukira kuti sitiyenera kugwiritsa ntchito manyowa osakhwima, zomwe zingangowonjezera kupezeka kwa Meloidogyne incognita.
6. Kuchulukitsa kugwiritsa ntchito feteleza wachilengedwe komanso kulimbikitsa kasamalidwe ka minda
Tiyenera kugwiritsa ntchito kwambiri nematode ulamuliro kwachilengedwenso fetereza (mwachitsanzo, munali Bacillus thuringiensis, wofiirira spore, etc.) kusintha nthaka tizilombo tating'onoting'ono zomera, mogwira kuteteza zimachitika nematodes, kumapangitsanso kukula, ndi kuchepetsa kuvulaza Meloidogyne incognita.
