Matenda a mphesa, njira zopewera.

Pakali pano, mphesa, nakulitsa kalelo, wakhala anasonkhanitsa okwanira nthenda zosiyanasiyana, zomwe tifunika kulimbana, chifukwa pali kuthekera kwa sanali mbewu. matenda mpesa anawagawa matenda ndipo sanali opatsirana.

1. Matenda opatsirana sanali ndi kuwonetseredwa chifukwa cha polojekitiyi chowawa wa zochitika zachilengedwe, monga matalala, chilala kapena kutentha. Nthawi zambiri, zomera akudwala, chifukwa oxidizes nthaka, kaya ndi mchere. Komanso, nthaka akhoza kupatsira chinyezi kapena kukhala osauka zakudya zosiyanasiyana zofunika kukula wabwinobwino mbewu. mfundo zonsezi zina chifukwa cha matenda a mphesa, ndipo ngakhale breakage ake.

Matendawa akhoza kuonekera chitukuko ofooka wa mpesa, mu maonekedwe a asymmetry, zowononga za mphukira ndi maonekedwe a necrosis. Pa tchire nthawi zambiri anapanga mawanga, mazira ndi zipatso anayamba prisyhat, zisa youma ndi kung'amba, kusintha mtundu wawo.

Ngati deta likupezeka mawonetseredwe mu nthawi, tchire angapulumuke.

2. Matenda a chikhalidwe opatsirana a mphesa ingafalire ku matenda kwa tchire wathanzi mabakiteriya, nkhungu kapena mavairasi. Gulu la matenda ndi oopsa kwambiri, makamaka chifukwa amamuchititsa kugunda nthawi yochepa chikhato lingamutsatire mbewu m'dera ndi ngakhale kuwawononga. Infection kumachitika ndi kulanda mabakiteriya oopsa ndipo spores ndi mphepo, nyama, madzi, komanso anthu ndi katundu ku mbali bwanji za zitsamba akufa pa tchire wathanzi.

Ndi mtundu uwu matenda ayenera combated ndi tanthauzo kudziwika ndi zopezeka: kuchita kupewa, kukhala chonde, kuchititsa kwaokha. Komabe, ngati kachilombo mpesa matenda anadutsa pa tchire wathanzi, ayenera yomweyo kuchititsa awonongedwe miyeso awo.

Ndi bwino kugwiritsa ntchito mphesa, amene kukana mkulu matenda osiyanasiyana ndi tizirombo. Iwo ananena kuti mitundu Loona za tchire zipatso ambiri atengeke matenda komanso kukhudzana ndi tizilombo zoipa. Mwachitsanzo, taganizirani matenda a mphesa, ndi chikhalidwe opatsirana.

1.Rak mizu. Pakachitika mlengalenga mbali ouma a mphesa makamaka kumpesa ndikamezetsanidwemo. Izi ntchito pogonjetsa ake pa kudula kapena kumezetsanitsa, komanso tizilombo infestation ndi chowawa zochitika zachilengedwe.

Pamene kumathandiza kuti zinthu zikhale mipesa mphesa unachitikira chidale m'madera kachilombo ndi mokakamizidwa moto ndi tizirombo pa zipangizo munda. Kwambiri mbande akhudzidwa kwathunthu kuchotsedwa.

2. chikuku. Anakhudzidwa tchire ali pa masamba mawanga ofiira kapena wachikasu. Infection limapezeka pa kutentha madigiri makumi awiri, pakalibe chinyezi. Disease akufotokozera kuchokera pansi pa chitsamba.

Pa matenda ndi tchire chikuku sprayed Bordeaux madzi, motero wagwa masamba ndi kuwotchedwa, ndi chinyezi nthaka anakhalabe.

3. cinoni - Disease zobiriwira mbali mpesa, m'kukoma maonekedwe a mawanga chikasu limene aumbike mwa nyengo yamvula otchedwa kufwanyulira imvi, zomwe zina chimafikira kwa maluwa, masamba ndi zipatso, Komabe posachedwapa kenako youma ndi kuguluka. Pamene nyengo yamvula mabakiteriya achulukane ndi kuwononga malo onse waukulu wa chitsamba.

M'pofunika kuchita kupewa matenda. Izi zimafunika wabwino provetrivaemost munda sikuloledwa chinyezi kudzikundikira. Ndi bwino kudzala zitsamba pamodzi mphepo, kupewa madambo ndi malo otsika a m'mbali.

Motero, poganizira za matenda a mphesa ndi ulamuliro, mwa njira zimene tingagwiritse lero, tisaiwale kuti yake zodzitetezera kukusalani kuthekera matenda mwa tizilombo mabakiteriya zitsamba.
