Mankhwala ophera tokha

herbicide yokometsera

Tikakhala ndi dimba lathu, nthawi zambiri timakhala ndi udzu, ndipo ngati sitingathe kuuchotsa bwino, udzu ukhoza kukhala wokhumudwitsa kwambiri. Ntchitoyi imatha kukhala yotopetsa komanso yotopetsa, ndipo nthawi zina timawononga ndalama pogula mankhwala ophera udzu kuti athe kuwapha mpaka kalekale. Lero tikambirana momwe tingapangire a herbicide yokometsera ndi njira zotani zogwirira ntchito mpaka kalekale.

M'nkhaniyi tikuwuzani zonse zomwe muyenera kudziwa kuti mupange mankhwala opangira udzu komanso mawonekedwe ake.

Momwe mungapangire herbicide yokometsera

zachilengedwe zopangira mankhwala ophera tizilombo

Kuti mupange mankhwala opangira herbicide, mutha kugwiritsa ntchito zinthu zosiyanasiyana. Malingana ndi mtundu wa udzu umene tikufuna kuuchotsa, tiyenera kugwiritsa ntchito chigawo chimodzi kapena china. Choyamba mwa izi ndikunyowetsa ndi madzi otentha. Mtundu uwu wa herbicide kunyumba ndi wosavuta kukonzekera. Choopsa kwambiri chomwe chingachitike popanga mankhwala a herbicide apanyumba ndikuti mutaya madzi otentha ndipo mutha kudziwotcha nokha. Simawononga kwambiri anthu komanso chilengedwe, choncho tikhoza kuzigwiritsa ntchito mosamala.

Timangofunika kuthira madzi pang'ono mumphika ndikubweretsa kwa chithupsa. Madzi owiritsa sangakhudze masamba ndi tsinde la zitsamba zomwe tikufuna kuzichotsa. Kugwiritsa ntchito madzi amtunduwu ndi njira yabwino kwambirimakamaka m’malo monga ming’alu ya m’mbali mwa msewu kapena m’malo okulirapo kumene mungafune kubzalanso namsongole akatha. M'kupita kwanthawi, madzi otenthawo sadzasiya mavuto aliwonse owopsa m'nthaka.

Chofunika ndi kuchigwiritsa ntchito pa zomera zomwe tikufuna kuwononga, chifukwa tikhoza kuwononga zomera zina, ndipo tilibe chifukwa chakuti zimamwaza madzi.

Mankhwala opangira tokha ndi moto

mchere ndi viniga

Zikuwoneka zopusa koma kugwiritsa ntchito kutentha molunjika pamasamba a namsongole kumapangitsa kuti mbewuyo kufota nthawi yomweyo ndipo kupha masamba aliwonse omwe atuluka kuchokera kumizu. Mutha kupeza zida zamoto pafupifupi m'sitolo iliyonse yomwe imakupatsani mwayi wogwiritsa ntchito kutentha mosayatsa kuposa momwe muyenera kuchitira.

Samalani ndi madera ouma kwambiri kapena omwe nthawi zambiri pamakhala moto. Apa ndipamene muyenera kusamala kuti musayambitse moto wosafunikira.

Mtundu wina wa herbicide wopangidwa kunyumba ndikuwonjezera sodium chloride. Izi ndizoposa mchere wamba wamba. Ndi mtundu wa herbicide wogwira mtima womwe uli ndi mbiri yakale yodziwika bwino, yomwe imagwiritsidwa ntchito kuwononga dothi la anthu omwe adagonjetsedwa. Ndipo ndi zimenezo mcherewo umalepheretsa zomera kumeranso. Popeza al ali ndi zotsatira zowononga nthaka kwa nthawi yayitali, ndikofunika kuti azigwiritsidwa ntchito kumalo omwe tikufuna kuti udzu usakule.

Nthaka sayenera kunyowa ndi mchere, makamaka m'miphika yokhala ndi zomera zina zomwe tikufuna kusunga. Moyenera, sungunulani gawo limodzi la mchere mu magawo asanu ndi atatu a madzi otentha. Timawonjezera pang'ono sopo wamadzimadzi kuti amamatire pamwamba. Akhoza kuthiridwa mu mabotolo opopera. Kuti mugwiritse ntchito, muyenera kuphimba kapena kumanga zomera zapafupi zomwe mukufuna kusunga ndikupopera masamba a udzu ndi yankho ili.

Viniga kuchotsa udzu

namsongole

Wina wopangira herbicide wakunyumba ndikuwonjezera vinyo wosasa pang'ono pamasamba a udzu. Ubwino wa chinthu ichi ndikuti chimakhala ndi zotsatira zake nthawi yomweyo. Vinigayo akapangidwa, amatha kuwoneka kuti amwalira nthawi yomweyo. Viniga woyera amagulitsidwa m'masitolo ogulitsa ndipo zotsatira zake ndikuti asidi wa asidi ndi pafupifupi 5% ya kuchuluka kwake. Izi zokha ndi zokwanira kupha udzu wambiri. Ngakhale mtundu wa mafakitale Acetic acid imatha kukhala ndi 20%, imatha kukhala yovulaza khungu, maso, kapena mapapo ngati itakoweredwa.

Viniga angagwiritsidwe ntchito m'njira zambiri. Chimodzi mwa izo ndi kupopera mbewu mankhwalawa. Choyenera ndi kupopera masamba a namsongole, kukumbukira kuchepetsa mame ochulukirapo pa zomera za m'munda kapena nthaka yapafupi yomwe tikufuna kuteteza. Angafunike kugwiritsidwanso ntchito, kuwonjezera zotsukira pang'ono zamadzimadzi zimathanso kukulitsa mphamvu ya mankhwala opangira kunyumba.

Tikhoza kusakaniza mchere ndi vinyo wosasa nthawi imodzi kuti tipange mankhwala amphamvu kwambiri opangira kunyumba. Sakanizani vinyo wosasa ndi chikho cha mchere ndi 3 malita a vinyo wosasa ndi osakaniza wangwiro. The osakaniza akhoza sprayed pa masamba a namsongole. Ngati mukufuna kuti ikhale yogwira mtima, mukhoza kuwonjezera sopo wamadzimadzi pang'ono.

Momwe mungachotsere namsongole

Anthu ambiri amanena kuti namsongole kulibe. Ndi zomera zomwe ubwino wake sunapezekebe. Komabe, ngati mukusokoneza mbewu zina zonse zomwe mukufuna kubzala m'munda mwanu ndipo mukukonzekera kudikirira kuti zabwinozi ndi ziti, mutha kugwiritsa ntchito mankhwala opangira udzu m'malo mwa mitundu yamankhwala Zimawononga ndalama ndipo zimatha kuipitsa chilengedwe. Zina zonse za zomera.

Moyenera, mankhwala ophera udzu omwe mumagwiritsa ntchito pochotsa udzu m'munda mwanu ndi wachilengedwe momwe mungathere kuti asawononge chilengedwe kapena nthaka. Mankhwala amphamvu opezeka mu herbicides, mankhwala ophera tizirombo, ndi ma fungicides amatha kuyipitsa kumwa madzi, madzi apansi ndi madzi apamtunda. Choncho, m'pofunika kwambiri kumvetsa zikuchokera mankhwala herbicides pamaso ntchito.

Ndi bwino kugwiritsira ntchito mankhwala opangidwa ndi zitsamba omwe alibe mankhwala kwa nthawi yayitali ndipo amathetsa vutoli osadetsa.

Ndikukhulupirira kuti ndi izi mutha kuphunzira zambiri zamomwe mungapangire mankhwala ophera tizilombo tokha.


Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.
