Ndikofunika kupewa kupezeka kwa matenda ndikudula njira zopatsirana. Njira zopatsira matenda zomwe zimafala kwambiri m'malo obiriwira makamaka zimaphatikiza mpweya, madzi, zamoyo ndi zina. Komabe, njira zopatsira matenda osiyanasiyana ndizosiyana. Alimi amasamba akuyenera kupanga njira zopewera ndi zopewera kutengera kufala kwa matenda osiyanasiyana.
Utsi + utsi ukhoza kuthetsa kufalikira kwa mpweya
Kupatsirana kwaposachedwa kwa mpweya ndiye njira yayikulu yopatsira tizilombo toyambitsa matenda. The spores opangidwa ndi bowa ndi ang'onoang'ono ndi kuwala, ndipo mosavuta kufalikira mofulumira ndi kutali ndi mpweya mafunde, monga imvi nkhungu, downy mildew, powdery mildew, etc. Matenda amene amafalikira mu greenhouses ndi airflow, chidwi ayenera kuperekedwa kwa comprehensiveness mu kupewa ndi kuchiza. Kutenga mmene imvi nkhungu mwachitsanzo, popewa ndi kuchiza matenda, sitiyenera ntchito kupopera mbewu mankhwalawa, komanso kuphatikiza ndi utsi fumigation kupha tizilombo tizilombo toyambitsa matenda inaimitsidwa mu mlengalenga.
Chepetsani kukhudzana kwa madzi ndi tizilombo toyambitsa matenda
Nthawi zambiri, matenda monga mabakiteriya, bowa, ndi oomycetes amatha kuchitika pansi pa kutentha kwambiri komanso chinyezi chambiri. Pakati pawo, matenda a mizu (matenda a bakiteriya) ndi matenda a oomycete amafalitsidwa makamaka kudzera m'madzi. Mabakiteriya ena ali ndi flagella, ndipo oomycetes amatha kupanga zoospores, zomwe zimafalitsidwa makamaka ndi mame omwe ali pamwamba pa zomera. Kwa matenda omwe amafalikira kudzera munjira iyi, ngati mukufuna kupewa matendawa, choyamba muyenera kulimbikitsa malamulo a chinyezi cha wowonjezera kutentha.
Zochita zenizeni: Sankhani filimu yokhetsedwa yapamwamba kwambiri kuti muchepetse kusungunuka pamwamba pa filimu yokhetsedwa; kuphimba nthaka ndi mulch, udzu, etc.; madzi pansi pa filimuyo ndikupereka mpweya wabwino komanso kuchotsa chinyezi. Tizilombo toyambitsa matenda timakhala m'nthaka kapena panthaka ndipo titha kufalitsa ndi madzi mukathirira. Waukulu mbali ya matenda kufala njira ndi kuti matenda pakati ndi zoonekeratu. Pamene ulimi wothirira ukupitirira, mabakiteriya a pathogenic akupitiriza kufalikira ndi kukulitsa dera la matenda. Choncho, kupewa matenda zomera pamene kuthirira.
Mwachidule, kudula njira yopatsirana kungathe kuchepetsa kuchuluka kwa masamba okhetsedwa, ndipo panthawi imodzimodziyo, kupewa ndi kulamulira matendawa ndi mankhwala owonetsera zizindikiro malinga ndi tizilombo toyambitsa matenda.
