Grey mold yematomatisi inowanzoitika panguva yemaruva uye fruiting, uye inogona kukuvadza maruva, michero, mashizha uye madzinde. Nguva yemaruva ndiyo yepamusoro yehutachiona. Chirwere chinogona kuitika kubva pakutanga kwemaruva kusvika kumichero. Kukuvadza kwacho kwakakomba mumakore ane tembiricha yakaderera uye kunoramba kuchinaya.
Grey mold yematomatisi inoitika kare, inogara kwenguva refu, uye inonyanya kukuvadza michero, saka inokonzera kurasikirwa kukuru.
1,Zviratidzo
Mashizha, mashizha, maruva nemichero zvinogona kukuvadza, asi kukuvadza kukuru kune muchero, kazhinji chirwere chechibereko chakasvibirira chinonyanya kuipa.
Chirwere cheshizha chinowanzotanga kubva kumucheto kweshizha uye chinopararira mukati chichitevedza tsinga dzebazi muchimiro che "V".
Pakutanga, inodiridzwa-semvura, uye mushure mekuvandudzwa, ine yero-brown, ine mipendero isina kujairika uye inochinjana rima uye chiedza mavhiri mavhiri.
Muganhu pakati pezvirwere uye hutano hutano huri pachena, uye zvishoma zvishoma zvegrey nechena mold inogadzirwa pamusoro.
Kana dzinde rine utachiona, rinotanga senzvimbo diki yakanyoroveswa nemvura, uye yobva yawedzera kuita oblong kana kuti isina kurongeka chimiro, chiedza chine brown. Kana hunyoro hwakakwirira, pane grey mold layer pamusoro penzvimbo yacho, uye mumatambudziko makuru, dzinde nemashizha pamusoro pechirwere chikamu chinofa.
Chirwere chemuchero, chiseko chinosara kana petals chinotanga kutapukirwa, chobva chapararira kune muchero kana dzinde, zvichiita kuti peel ipfuure, uye kune gobvu grey mold layer, semvura inoora.

Kudzora kwekurima
- Ecological control
Nguva yekufefetera mumangwanani pamazuva ezuva, kunyanya mune solar greenhouse nemvura yekudiridza, rechipiri kusvika kune rechitatu mazuva mushure mekudiridza, vhura tuyere kwemaminitsi gumi nemashanu mushure mekuvhura keteni mangwanani, uye wozovhara vent. Kana tembiricha mu solar greenhouse ichikwira kusvika 30 ° C, wobva wavhura tuyere zvishoma nezvishoma. Tembiricha yepamusoro inopfuura 31 ℃ inogona kuderedza kumera kwespores uye kuderedza kuitika kwezvirwere. Masikati, tembiricha mugreenhouse yezuva inochengetwa pa20 ~ 25 ° C, uye mhepo inovharwa kana tembiricha inodonha kusvika 20 ° C masikati. Tembiricha yehusiku inochengetwa pa15 ~ 17 ℃. Pamazuva ane makore, maererano nemamiriro ekunze uye nharaunda yekurima, mhepo inofanira kusunungurwa zvakakodzera kuderedza hunyoro.
- Kurimwa kwekudzivirira zvirwere
Kurudzira kurimwa kwediki uye yakakwira cardigan mulching firimu, ita tekinoroji yekudiridza, kuderedza hunyoro uye kuderedza chirwere. Kudiridza kunofanira kuitwa mangwanani pamazuva ezuva kudzivirira kuwandisa. Kudiridza zvine mwero pakutanga kwechirwere. Mushure mekudiridza, teerera kuregedza mhepo uye kubvisa hunyoro. Mushure mechirwere, bvisa muchero unorwara uye mashizha munguva uye unyatsobata navo kudzivirira kupararira kwehutachiona. Mushure mekuunganidza michero uye musati madyarwa, zvakasara zvechirwere zvinobviswa kuti zvichenese munda uye kuderedza utachiona hwehutachiona.
- Kudzora muviri
Kushandiswa zhizha uye matsutso tembiricha, akavharwa zuva girinihausi kweinopfuura vhiki, kushandisa chiedza chezuva kuita tembiricha ari girinihausi kukwira kupfuura 70 ° C, yakakwirira tembiricha disinfection.
Kudzora kwemakemikari
Zvinoenderana nehunhu hwegrey mold yematomatisi, zvinodikanwa kusarudza mhando dzemushonga dzakakodzera kuti udzore nesainzi. Kana madomasi akanyikwa mumaruva, mune rakagadzirwa dip ruva diluent, 50% yehuwandu hwesaprophyticus wettable powder, kana 50% ye doxycarb wettable powder, nezvimwewo, inowedzerwa kudzivirira kutapukira kwebhakitiriya. Usati wadyarwa, madomasi anofanira kunyatsoiswa disinfected ne50% carbendazim wettable powder 500 times liquid, kana 50% Suacrine wettable powder ka500 liquid pfapfaidzo kamwe kuderedza huwandu hwehutachiona hwepathogenic. Pakutanga kwechirwere, 2000 nguva mvura ye50% Suk flexible wettable powder, 500 times liquid ye50% carbendazam wettable powder, kana ka1500 mvura ye50% puhain wettable powder yakashandiswa kudzivirira nekudzora spray, kamwe chete 7 to Mazuva gumi, kwe2 kusvika ku3 nguva dzakatevedzana. Unogonawo kusarudza 45% Chlorothalonil chiutsi agent kana 10% Sukline chiutsi agent, 250 magiramu per mu greenhouse, yakavharwa greenhouse pashure 7 kusvika 8 nzvimbo manheru kuti chiedza kudzivirira utsi. Apo chirwere chacho chakakomba, mushure mokubvisa mashizha ane chirwere, michero uye mashizha, mamiririri ari pamusoro apa uye nzira dzinotorwa kuti dzirege kudzivirira uye kuporesa 2 kusvika ku3 nguva.
