Dera la Hebei ndi mlimi wosanjikiza, katundu 120,000, masiku 86 tsopano, masiku awiriwa ndi amodzi mwa imfa zaposachedwa za tsiku ndi tsiku.

1. Zizindikiro zachipatala

Nkhuku zowawa zinayamba kuchepa kapena kusadya, kusowa mphamvu, kusakonda kuyenda, mapiko ogwetsa, nthenga zotayirira, kukhala pakona, maso otsekedwa, otopa, osayanjanitsika ndi dziko lakunja, ndowe zakuda kapena zamadzi, atagwa pansi, mutu wopindika chammbuyo, imfa yaulesi. Ofooka malamulo, utachepa chilakolako cha kudya, atagona pansi, sangathe kuima, mutu ndi mapiko nthenga kugwa, imfa mwadzidzidzi, kuwala pambuyo chakudya mkamwa kulavulira asidi madzi, kutulutsa chikasu wobiriwira, mdima kuchepetsa ndowe, limodzi ndi ntchofu.

2.Necropsy kwa zizindikiro

Kutupa kwa m'mimba, mtundu wotumbululuka, mtundu wonyezimira, gawo la matumbo amatumbo ofiira ofiira kapena akuda. Panali zidutswa zambiri za matumbo a m'matumbo osakanikirana ndi madzimadzi kapena otuluka mu lumen ya m'mimba. Pambuyo pa necrosis ya m'mimba mucosa ndi njira yayitali, mucosa ndi yoyera-yoyera komanso pafupi ndi khoma la m'mimba, ndipo chubu chamatumbo chimadzazidwa ndi necrosis.

5. Ulendo wobwereza wamankhwala

Patsiku lachiŵiri la mankhwala, mzimuwo unawongoleredwa ndipo madyedwe anawongoleredwa.
Patsiku lachitatu la utsogoleri, palibe nkhuku zakufa komanso zopanda matenda zomwe zidawonekera.
Patsiku lachinayi laulamuliro, chopondapo chidasinthidwa bwino ndikuchiritsidwa.

6.njira zodzitetezera

(1) Osadyetsa chakudya chankhungu komanso chowonongeka

Kusagwiritsa ntchito zoyala zankhungu ndi chakudya ndiye njira yayikulu yopewera aspergillosis. M'chilimwe ndi m'dzinja kutentha kwakukulu ndi chinyezi chambiri, kuchuluka kwa chakudya chogulidwa nthawi iliyonse chiyenera kuchepetsedwa. Ndibwino kuti mugwiritse ntchito mkati mwa sabata limodzi kuti mutsimikizire kutsitsimuka kwa chakudya. Kudyetsa ayenera kugwiritsidwa ntchito kangapo, makamaka ntchito chonyowa ufa ayenera kudyetsedwa zochepa kawirikawiri kuwonjezera, ndipo nthawi zambiri homogenization.

(2) Gwirani ntchito yabwino yoyeretsa ndi kuyeretsa khola la nkhuku

Sambani mothira madzi kapena kasupe kamodzi kapena kawiri patsiku kuti nkhungu isakule. Khola la nkhuku litseke zenera kuti ntchentche zisalowe. Choncho, nkhuku nyumba kukhala woyera ndi youma, osati yonyowa. Sabata iliyonse, sungani mankhwala ophera tizilombo toyambitsa matenda omwe amatha kupha nkhungu ndi mafangasi, komanso chitani ntchito yabwino yothira madzi akumwa. Ngati pad zakuthupi ndi nkhungu, ziyenera kusinthidwa pakapita nthawi.

(3) Kulimbitsa mpweya wabwino m’nyumba

Chilimwe kutentha ndi mkulu, ayenera kulimbikitsa mpweya wabwino mu nkhuku nyumba, kuti atulutse nyumba zauve mpweya wotentha ndi ammonia, hydrogen sulfide ndi mpweya wina zoipa, ndipo angathe kuchepetsa nyumba kutentha, chinyezi ndi chiwerengero cha nkhungu mu mlengalenga. m'nyumba. Chifukwa nkhungu mu mlengalenga, makamaka mwa kupuma thirakiti ndi matenda a nkhuku, nkhungu zochepa, mwayi wochepa matenda. Pamene tsiku likutentha kwambiri, mpweya wabwino wa mpweya wachilengedwe umakhala wochepa. Ngati ndi kotheka, tsegulani fan yotulutsa mpweya kuti muwonjezere kuchuluka kwa mpweya wotulutsa.
