Kugwiritsa ntchito
Paraquat imatha kulamulira mitundu yonse ya namsongole pachaka;Imakhala ndi mphamvu yopha namsongole osatha, koma tsinde ndi mizu yake yapansi panthaka imatha kuphuka nthambi zatsopano;Izo zinalibe mphamvu pa lignified Brown zimayambira ndi mitengo ikuluikulu.Ndi yoyenera kuletsa udzu m'munda wa zipatso, m'munda wa mabulosi, m'minda ya mphira ndi lamba wa nkhalango.Itha kugwiritsidwanso ntchito pochotsa udzu m'malo osalimidwa, m'mphepete mwa msewu komanso m'mphepete mwa msewu.Kupopera mbewu molunjika kutha kugwiritsidwa ntchito pochotsa udzu wa chimanga, nzimbe, soya ndi nazale.
Ikhoza kulamulira mitundu yonse ya namsongole pachaka;Imakhala ndi mphamvu yopha namsongole osatha, koma tsinde ndi mizu yake yapansi panthaka imatha kuphuka nthambi zatsopano;Izo zinalibe mphamvu pa lignified Brown zimayambira ndi mitengo ikuluikulu.Ndi yoyenera kuletsa udzu m'munda wa zipatso, m'munda wa mabulosi, m'minda ya mphira ndi lamba wa nkhalango.Itha kugwiritsidwanso ntchito pochotsa udzu m'malo osalimidwa, m'mphepete mwa msewu komanso m'mphepete mwa msewu.Kupopera mbewu molunjika kutha kugwiritsidwa ntchito pochotsa udzu wa chimanga, nzimbe, soya ndi nazale.
2.3 Mlingo ndi kugwiritsa ntchito
1. minda ya zipatso, minda ya mabulosi, minda ya tiyi, minda ya mphira, ndi malamba a m’nkhalango amagwiritsidwa ntchito pa udzu.Iwo ali mu nthawi yamphamvu.Amagwiritsa ntchito madzi 20% 1500-3000 milliliters pa hekitala ndikupopera mofanana udzu ndi tsinde ndi masamba.Pamene namsongole akukula kupitirira 30cm, mlingo uyenera kuwirikiza kawiri.Paraquat idzagwiritsidwa ntchito pochotsa mankhwala.Madzi abwino adzagwiritsidwa ntchito kuwonjezera madzi.The madzi mankhwala adzakhala sprayed pa zobiriwira zimayambira ndi masamba a namsongole monga wogawana mmene ndingathere, osati pansi.
2. M'minda yambewu ya mizere ikuluikulu monga chimanga, nzimbe ndi soya zitha kukonzedwa musanabzale kapena mutabzala musanabzale.
3. Zochitika zothandiza zimasonyeza kuti paraquat alibe zotsatira zoonekeratu pa Rehmannia glutinosa Kuwala kumatha kufulumizitsa mphamvu ya paraquat, ndipo zotsatira zake zimakhala mofulumira masiku a dzuwa;Mvula ola limodzi pambuyo mankhwala analibe mphamvu pa efficacy.
Mbali ndi zotsatira
1. Paraquat ndi mankhwala owononga udzu.Amagwiritsidwa ntchito m'minda ndi nthawi ya kukula kwa mbewu.Ndikoletsedwa kuipitsa mbewu pofuna kupewa kuwonongeka kwa mankhwala.
2. Njira zodzitetezera ziyenera kuchitidwa panthawi yoperekera ndi kupopera mankhwala, ndipo magolovesi a labala, masks ndi zovala zogwirira ntchito ziyenera kuvalidwa.Ngati mankhwalawa agwera m'maso kapena pakhungu, muzimutsuka nthawi yomweyo.
3. Mukamagwiritsa ntchito, musayandamitse mankhwala amadzimadzi pamitengo ya zipatso kapena mbewu zina.Munda wa masamba uyenera kugwiritsidwa ntchito ngati palibe masamba.
4. Kupopera mbewu mankhwalawa kukhale kofanana ndi kolingalira.0.1% ufa wochapira ukhoza kuwonjezeredwa ku mankhwala amadzimadzi kuti apititse patsogolo kumamatira kwa mankhwala amadzimadzi.Kuchita bwino kungathe kutsimikiziridwa ngati mvula ikugwa pakatha mphindi 30 mutagwiritsa ntchito.
