Nguva yakakodzera yekushandisa mushonga wesora inguva dza 6 o'clock manheru.Nekuda kwekushisa kwakadzika uye hunyoro hwepamusoro panguva ino, mvura ichagara pamashizha emasora kwenguva yakareba, uye masora anogona kunyatsotora mishonga yemishonga.Zvinobatsira kuvandudza mhedzisiro yekusakura, uye panguva imwechete, kuchengetedzwa kwembeu yechibage kunogona kuvandudzwa, uye phytotoxicity haisi nyore kuitika.

Ndeipi nguva yekushandisa mishonga yesora mushure mechibage chembesa?

1. Nekuda kwekuti mushonga wesora uchangobuda wakapfapfaidzwa, zvinotora maawa maviri kusvika matanhatu kuti utore.Mumaawa 2-6 aya, kana mhedzisiro yemishonga yesora iri yakanaka inowanzoenderana netembiricha uye hunyoro hwemhepo.Mwaya mangwanani, kana masikati uye masikati kana kunze kwaoma.

2. Nekuda kwekushisa kwakanyanya, chiedza chakasimba, uye kukurumidza kuvhuvhuta kwemushonga wemvura, mushonga wemvura unobuda mushure menguva pfupi mushure mekupfapfaidza, kuitira kuti huwandu hwemushonga hunopinda mumasora huve hushoma, izvo zvinozoita kuti kusabatwa kwakakwana, zvichikanganisa herbicidal effect.Pakupfapfaidza panguva yekupisa uye kusanaya kwemvura, mbesa dzechibage dzinowanzoita phytotoxicity.

3. Nguva yakakodzera yekupfapfaidza ndeye 6 o'clock manheru, nekuti panguva ino, tembiricha yakadzikira, mwando wakakwira, mvura inogara pamashizha emasora kwenguva yakareba, uye sora rinogona kunyura zvizere. mishonga yesora., inobatsira pakuita kuti kuve nechokwadi chekusakura, uye mishonga yemanheru inogonawo kuvandudza kuchengetedzwa kwezviyo zvezviyo, uye hazvisi nyore kukonzera phytotoxicity.

4. Sezvo akawanda emishonga yesora mushure mekumera muchibage ari nicosulfuron-methyl, mamwe marudzi echibage anonzwisisa chikamu ichi uye anowanzoita phytotoxicity, saka hazvina kukodzera kuminda yechibage kudyara chibage chinotapira, waxy corn, Denghai series nezvimwe. mhando dzinofanirwa kupfapfaidzwa , kudzivirira phytotoxicity, kune itsva mhando dzechibage, zvinodikanwa kuti uedze uye wozosimudzira.

Nzira yekushandisa sei post-emergence herbicides muchibage?

1. Tarisa kukura kwehuswa

(1) Pakupfapfaidza mishonga yesora mushure memhodzi yechibage, varimi vazhinji vanofunga kuti kana sora richiva diki, kurwisa kunoita kushoma uye kuuraya huswa zviri nyore, asi handizvo.

(2) Nekuti huswa hudiki, hapana nzvimbo yemishonga, uye kusakura hakuna kunaka.Zera rakanakisa reuswa 2 mashizha uye 1 moyo kune 4 mashizha uye 1 moyo.Panguva ino, masora ane imwe nzvimbo yekushandisa.Kuramba masora hakusi kukuru, saka kusakura kwekuita kuri nani.

2. Mhando dzechibage

Nekuda kwekuti mishonga yakawanda inouraya sora muchibage ndeye nicosulfuron-methyl, mamwe marudzi echibage anonzwisisa chikamu ichi uye anowanzoita phytotoxicity, saka hazvibviri kupfapfaidza minda yechibage uko kunorimwa chibage chinotapira, waxy corn, Denghai series nemamwe marudzi.Kugadzira phytotoxicity, mhando dzechibage itsva dzinoda kuongororwa dzisati dzasimudzirwa.

3. Dambudziko rekusanganisa mishonga yezvipembenene

Mishonga yeOrganophosphorus haifanirwe kumwayiwa kwemazuva manomwe mbesa isati yasvika uye mushure mekumwaya, zvikasadaro zviri nyore kukonzera phytotoxicity, asi inogona kusanganiswa nepyrethroid.Mushonga unozadza mwoyo.

4. Kuramba kwesora pacharo

Mumakore achangopfuura, kugona kwemasora kuramba kushushikana kwakavandudzwa.Kuti udzivise kubuda kwakanyanyisa kwemvura mumuviri, masora anokura asina kusimba uye akasimba, asi anokura grey uye mapfupi, uye zera chairo reuswa harisi diki.Masora anonyanya kuvharwa nediki chena fluff muviri wese kuderedza kubuda kwemvura.
