Kwirinda no kuvura ibara ryinyanya ryinyanya

Icyatsi kibisi cyinyanya kiboneka cyane mugihe cyo kurabyo no kwera, kandi gishobora kwangiza indabyo, imbuto, amababi nigiti. Igihe cyo kumera ni impinga yo kwandura. Indwara irashobora kubaho kuva itangiye kurabyo kugeza imbuto. Ibyangiritse birakomeye mumyaka hamwe nubushyuhe buke nikirere cyimvura ikomeza.

Icyatsi kibisi cyinyanya kibaho hakiri kare, kimara igihe kinini, kandi cyangiza cyane imbuto, bityo gitera igihombo kinini.

1、Ibimenyetso

Ibiti, amababi, indabyo n'imbuto birashobora kwangiza, ariko ingaruka nyamukuru ku mbuto, ubusanzwe indwara yimbuto yicyatsi irakomeye.

Indwara yibibabi mubisanzwe itangirira kumutwe wikibabi ikwirakwira imbere mumitsi yishami muburyo bwa "V".

Ubwa mbere, ni amazi, kandi nyuma yiterambere, ni umuhondo-umukara, ufite impande zidasanzwe kandi uhinduranya ibimenyetso byijimye kandi byoroheje.

Imipaka iri hagati yinyama zirwaye kandi zifite ubuzima ziragaragara, kandi umubare muto wimyenda yera nuwera uboneka hejuru.

Iyo uruti rwanduye, rutangira ari ahantu hato huzuye amazi, hanyuma rukaguka muburyo butagaragara cyangwa budasanzwe, bwijimye. Iyo ubuhehere buri hejuru, haba hari ibara ryijimye hejuru yikibanza, kandi mubihe bikomeye, uruti namababi hejuru yindwara bipfa

Indwara zimbuto, agasuzuguro gasigaye cyangwa amababi yabanje kwandura, hanyuma bigakwirakwira ku mbuto cyangwa ku gihuru, bikavamo igishishwa kijimye, kandi hariho igicucu cyijimye cyinshi, nkamazi abora.

uburyo bwo kugenzura

Kugenzura ubuhinzi

• Kugenzura ibidukikije

Guhumeka mugihe cya mugitondo kumunsi wizuba, cyane cyane muri parike yizuba hamwe no kuhira amazi, iminsi ya kabiri kugeza kumunsi wa gatatu nyuma yo kuhira, fungura tuyere muminota 15 nyuma yo gufungura umwenda mugitondo, hanyuma ufunge umuyaga. Iyo ubushyuhe muri parike yizuba buzamutse bugera kuri 30 ° C, hanyuma fungura buhoro buhoro tuyere. Ubushyuhe bwo hejuru buri hejuru ya 31 ℃ burashobora kugabanya umuvuduko wa spore no kugabanya indwara. Ku manywa, ubushyuhe buri muri parike yizuba bugumaho kuri 20 ~ 25 ° C, kandi umuyaga ugafungwa iyo ubushyuhe bugabanutse kugera kuri 20 ° C nyuma ya saa sita. Ubushyuhe bwijoro bubikwa kuri 15 ~ 17 ℃. Ku minsi yibicu, ukurikije ikirere n’ibidukikije bihingwa, umuyaga ugomba kurekurwa neza kugirango ugabanye ubuhehere.

• Guhinga kurwanya indwara

Guteza imbere guhinga firime ntoya kandi ndende ya karigisi, gukora ikoranabuhanga ryo kuhira imyaka, kugabanya ubushuhe no kugabanya indwara. Kuvomera bigomba gukorwa mugitondo kumunsi wizuba kugirango wirinde kurenza urugero. Kuvomera neza mu ntangiriro yindwara. Nyuma yo kuvomera, witondere kureka umuyaga no gukuraho ubuhehere. Nyuma yindwara, kura imbuto n'amababi arwaye mugihe gikwiye kandi ubyitondere neza kugirango wirinde ikwirakwizwa rya mikorobe. Nyuma yo gukusanya imbuto na mbere yo gutera ingemwe, ibisigazwa byindwara bivanwaho kugirango bisukure umurima kandi bigabanye kwandura bagiteri.

• Kugenzura umubiri

Gukoresha ubushyuhe bwo mu cyi no mu gihe cyizuba, gufunga izuba rirenze icyumweru, gukoresha urumuri rwizuba kugirango ubushyuhe muri parike buzamuke burenze 70 ° C, kwanduza ubushyuhe bwinshi.

Kugenzura imiti

Ukurikije ibiranga ibara ryinyanya ryinyanya, birakenewe guhitamo ubwoko bwimiti ikwiye kugirango uyigenzure mubuhanga. Iyo inyanya zishizwe mumurabyo, mumashanyarazi yateguwe neza, 50% yumubare wifu wa saprophyticus wettable, cyangwa 50% yifu ya doxycarb wettable, nibindi, byongeweho kugirango wirinde kwandura bagiteri. Mbere yo gutera, inyanya zigomba kwanduzwa neza hamwe na 50% ya karbendazim yifu yifu inshuro 500, cyangwa 50% ifu ya Suacrine wettable inshuro 500 spray inshuro imwe kugirango igabanye umubare wa bagiteri zitera indwara. Intangiriro yindwara, inshuro 2000 amazi ya 50% ya Suk yoroheje yifu yifu, inshuro 500 zamazi ya 50% yifu ya karbendazam, cyangwa inshuro 1500 amazi ya 50% yifu ya puhain yakoreshejwe mugukumira no kurwanya spray, rimwe kuri 7 kugeza Iminsi 10, inshuro 2 kugeza kuri 3 zikurikiranye. Irashobora kandi guhitamo 45% yumwotsi wa Chlorothalonil cyangwa 10% yumwotsi wa Sukline, garama 250 kuri pariki ya parike, gufunga parike nyuma y’ahantu 7 kugeza 8 nimugoroba kugirango wirinde umwotsi. Iyo indwara ikomeye, nyuma yo gukuraho amababi arwaye, imbuto n'ibiti, imiti yavuzwe haruguru nuburyo bufatwa kugirango ubundi buryo bwo gukumira no gukiza inshuro 2 kugeza kuri 3.
