Matenda a chimanga matenda oyambira ayamba kuchitika. Njira zotsatirazi zitha kutengedwa popewa ndi kuwongolera:
1.Imani mitundu yosagonjetseka.
2. Zodwala zodwala kuchokera kumunda, chilili ndi tizilombo toyambitsa matenda.
25 Kuphatikiza apo, palibe Trullage ndi zotupa zopitilira zomwe zimachulukitsa kupezeka kwa matenda
.
1, tsamba limadetsa nkhawa
Kutumiza kwa Timegen ndi Zowonjezera:
Timegen ya chimanga masamba opindika matenda opatsirana pophatikiza hyphae kapena ma condium ku matenda omwe amadwala. Kufalikira kwa Masamba a Masamba Oseketsa Matenda sikungokhudzana ndi matenda omwe amakana chimanga, komanso ogwirizana kwambiri ndi zachilengedwe. Kutentha kwafika 20 ℃ -25 ℃ Ndipo chinyontho chinyontho chimafika pa 90%, nkothandiza pakukula kwa matenda. Ngati zimapangitsa kuti zitheke masiku angapo otsatizana, zimatha kuyambitsa kukula kwa vitiligo. Kuphatikiza apo, kuyerekeza mwadzidzidzi pa masiku a Wiggy kungayambitsenso kufalikira kwa kuwonongeka kwa macular.
Kuteteza Mankhwala ndi Kuwongolera:
Fungicides monga azoxystrobin ndi proptuconazole Azoxystrodun angagwiritsidwe ntchito kupewa kupewa ndikuwongolera masamba opindika.
Ngati nthawi yokula ya chimanga yachedwa, feteleza wa masamba a monopotassium phosphasite polimbikitsa kukhwima koyambirira kungathenso kuwonjezeredwa ndikugwiritsa ntchito nthawi yomweyo.
2, matenda a bulauni
Zimachitika pamasamba a chimanga, zotupa za masamba, ndipo zimachitika kumapeto kwa masamba apamwamba, ndi mawanga ambiri pamsewu wamasamba ndi maulendo a masamba, nthawi zambiri zimadzaza m'mizere. Poyamba, ndi malo ochepa achikasu kapena ofiira, ndi mawanga omwe ali ozungulira kapena odetsa. Minyewa ya tsamba pafupi ndi prosersunce nthawi zambiri imakhala yofiyira, ndipo malo ang'onoang'ono amadwala nthawi zambiri amasonkhana pamodzi. Zovuta kwambiri, magawo angapo kapena masamba onse amaphimbidwa ndi mawanga a matenda, ndipo mawanga akuluakulu a masamba amawonekera pamtunda wamasamba, m'chigawo cha matenda oyambitsidwa, masamba a syle cell anali mu dziko lakufa, ndipo ufa wa bulauni (choponya cha pathogen) chidabalalitsidwa. Tsamba lodwala silinagawika pang'ono, ndipo mitsempha ya masamba ndi mtolo wa ruscula umakhala ngati mafilimu. Ngati kutentha kumakhala kwakukulu, chinyezi chimakhala chambiri, ndipo pali masiku ambiri amvula mu Julayi ndi Ogasiti. Zili bwino chifukwa cha matendawa. M'madera okhala ndi dothi labwino, masamba amatembenukira chikasu ndi matenda. M'madera okhala ndi chonde champhamvu kwambiri, chimanga chimakhala cholimba, masamba ndi obiriwira obiriwira, ndipo matendawa ndi ofatsa kapena ngakhale osapezeka. Nthawi zambiri, matendawa amakonda kupezeka pakakhala masamba 8-10 mu chimanga, ndipo nthawi zambiri samachitika pambuyo pa masamba 12 mu chimanga.
Kuteteza Mankhwala ndi Kuwongolera:
Kuteteza koyambirira Mangani Matenda a Mangani Matenda a Mangani. Kupezeka kwa bulauni malo a bulauni ndi matenda ena apamwamba kwambiri Pyrazolidinoxystrosun, omwe amatha kusintha kupsinjika kwa chomerachokha.
, Kupezeka kwa bulauni ndi matenda ena apamwamba kuti ayendenso ndi ma 800 a 25% pyrazolidinoxyrobin, omwe amatha kusintha kupsinjika kwa chomerachokha.
3.Nostn Anthrax
Kutumiza kwa tizilombo toyambitsa matenda: Itha kulowetsedwa ndi kuyenda kwa mpweya ndi mbewu, koma nthawi zambiri kuchuluka kwa mbewa ndi kotsika, makamaka chifukwa sporgen spores pambuyo pompopompo zimafalikira kwa mbande ndi mvula chifukwa cha matenda. Malo opumira amatha kuwoneka 4 mpaka 10 patatha masiku atatenga kachilomboka, ndipo Cedidium amapangidwa.
Kuwongolera Chemican: Ngati pali matenda, ndipo pamakhala zinthu zovuta, ndikofunikira kutembenuka kwa mankhwalawa momwe mungathere, m'modzi kapena angapo angagwiritsidwe ntchito kupukutirapo popewa monga phenoxymeclozole, PYNIDIIN, syricycercetin, pyrazole e ever, etc.
