Kukhudzana ndi mankhwala a herbicides

Kodi mankhwala a herbicides ndi chiyani?

Mankhwala a herbicidesndi mankhwala omwe amagwiritsidwa ntchito kuwononga kapena kulepheretsa kukula kwa udzu. Mankhwala a herbicide amagwiritsidwa ntchito kwambiri paulimi ndi ulimi wamaluwa kuti athandize alimi ndi olima kuti minda yawo ikhale yaudongo komanso yogwira ntchito bwino. Mankhwala a herbicides amatha kugawidwa m'magulu angapo, makamaka kuphatikizakukhudzana ndi herbicidesndimankhwala herbicides.

Chifukwa chiyani ndikofunikira kumvetsetsa mankhwala ophera udzu?

Kumvetsetsa momwe mitundu yosiyanasiyana ya mankhwala ophera udzu imagwirira ntchito, momwe imagwirira ntchito mwachangu, komwe imayikidwa, komanso momwe imagwirira ntchito ndikofunikira posankha mankhwala oyenera. Izi sizidzangothandiza kuwongolera udzu bwino, komanso kuchepetsa kuwononga chilengedwe ndikuteteza thanzi la mbewu zanu.

Lumikizanani ndi herbicide

Kachitidwe
Kukhudzana ndi mankhwala a herbicides amapha mbali za mbewu pokumana nazo. Mankhwala ophera udzuwa sasuntha kapena kusuntha mkati mwa mbewu motero amagwira ntchito pazigawo zomwe zakhudzana.

Liwiro
Mankhwala opha udzu nthawi zambiri amagwira ntchito mwachangu. Kuwonongeka kowoneka kwa mbewu nthawi zambiri kumachitika mkati mwa maola kapena masiku.

Kugwiritsa ntchito
Mankhwala ophera udzuwa amagwiritsidwa ntchito poletsaudzu wapachaka. Iwo sagwira ntchito paudzu osathachifukwa safika ku mizu ya zomera.

Paraquat 20% SLndi mankhwala ophera udzu, omwe makamaka amapha nembanemba ya chloroplast ya namsongole polumikizana ndi mbali zobiriwira za namsongole. Zitha kukhudza mapangidwe a chlorophyll mu namsongole komanso zimakhudza photosynthesis ya namsongole, potero kuthetseratu kukula kwa namsongole. Itha kuwononga mbewu zonse za monocotyledonous ndi dicotyledonous nthawi imodzi. Nthawi zambiri, namsongole amatha kusinthika pakatha maola awiri kapena atatu mutabzala.

DiquatNthawi zambiri amagwiritsidwa ntchito ngati njira yolumikizirana yopha bioherbicide. Itha kutengeka msanga ndi minyewa yobiriwira ya zomera ndipo imasiya kugwira ntchito itangokhudza nthaka. Amagwiritsidwa ntchito popalira m'minda, m'minda ya zipatso, m'minda yosalimidwa, komanso musanakolole. Itha kugwiritsidwanso ntchito ngati Zimayambira ndi masamba a mbatata ndi mbatata zimafota. M'malo omwe udzu wa gramineous ndi wovuta, ndi bwino kugwiritsa ntchito paraquat pamodzi.

Ubwino ndi kuipa kwa kukhudzana ndi herbicides

Ubwino
Kuchita mwachangu kumadera omwe amafunikira kuwongolera mwachangu.
Zothandiza kwambiri pa udzu wapachaka.
Zoipa
Sichimapha mizu, choncho sichigwira ntchito pa namsongole osatha.
Imafunika kuphimba bwino masamba a chomera kuti ikhale yogwira mtima.

Mankhwala a Herbicide

Kachitidwe
Mankhwala a herbicide amatengedwa ndi mmera ndikusuntha m'magulu ake onse ndipo amatha kufikira mizu ndi mbali zina za mmera, motero amapha mbewu yonse.

Liwiro
Mlingo wa zochita za mankhwala a herbicides nthawi zambiri umakhala wapang'onopang'ono chifukwa amatenga nthawi kuti amwedwe ndi mmera ndikuyendayenda monsemo.

Kugwiritsa ntchito
Mankhwala ophera udzuwa amatha kupha udzu wapachaka komanso wosatha chifukwa amatha kupha mizu ya mmera.

Glyphosatendi mankhwala osasankha herbicide. Ndikofunika kupewa kuwononga mbewu mukamagwiritsa ntchito kuti mupewe phytotoxicity. Amagwiritsidwa ntchito pamasamba a zomera kuti aphe zomera ndi udzu. Imakhala ndi zotsatira zabwino pamasiku adzuwa komanso kutentha kwambiri. Mtundu wa mchere wa sodium wa glyphosate umagwiritsidwa ntchito kuwongolera kukula kwa mbewu ndikukhwimitsa mbewu zina.

2,4-D, yotchedwa 2,4-dichlorophenoxyacetic acid, ndi mankhwala omwe amagwiritsidwa ntchito kwambiri posankha herbicide. Amagwiritsidwa ntchito kwambiri polimbana ndi udzu wamasamba popanda kuwononga udzu.

Ubwino ndi kuipa kwa zokhudza zonse herbicides

Ubwino

Kutha kupha mizu ya zomera, kuwapangitsa kukhala ogwira ntchito pa udzu osatha.
Zomera zimangofunika kuphimba pang'ono pamene zikuyenda mkati mwa mbewuyo.

Zoipa

Kuchita pang'onopang'ono, sikoyenera pazochitika zomwe zotsatira zachangu zimafunikira.
Ikhoza kukhudza kwambiri chilengedwe komanso zomera zomwe sizili zolinga.

Kusiyana kwakukulu pakati pa mankhwala a herbicides ndi systemic herbicides

Kufotokozera
Kulumikizana ndi herbicides kumafunika kuphimba masamba onse a mmerawo, ndipo mbali zonse za mmera zomwe sizinakhudzidwe ndi herbicide zidzapulumuka. Mosiyana ndi izi, mankhwala a herbicides amafunikira kufalikira pang'ono chabe chifukwa amayenda mkati mwa mbewu.

Kuchita bwino pazitsamba zosatha
Mankhwala ophera udzu sagwira ntchito bwino pa udzu wosatha wokhala ndi mizu yotalikirapo, pomwe mankhwala ophera udzu amatha kupha udzu wosatha pofika kumizu.

Gwiritsani Ntchito Milandu
Mankhwala ophera udzu nthawi zambiri amagwiritsidwa ntchito pogwetsa udzu mwachangu, makamaka m'malo omwe kukhudzana ndi dothi kumatha kuwononga mbewu zomwe mukufuna, pomwe mankhwala opha udzu amagwiritsidwa ntchito pothana ndi namsongole kwanthawi yayitali.

Kufotokozera mwachidule

Mankhwala a herbicides okhudzana ndi dongosolo lililonse ali ndi njira yakeyake yochitira, liwiro, komanso momwe amagwiritsidwira ntchito. Ndi mankhwala ati omwe angasankhe zimatengera mtundu wa udzu, kuchuluka kwa kuwongolera kofunikira, komanso malingaliro a chilengedwe. Kumvetsetsa kusiyana kwake ndi momwe angagwiritsire ntchito mankhwala ophera udzu awiriwa kudzathandiza kuti kasamalidwe ka udzu kakhale kothandiza.
