Namsongole wapachaka ndi zomera zomwe zimamaliza moyo wawo—kuchokera kumera kupita kukupanga mbewu ndi kufa—m’chaka chimodzi. Zitha kugawidwa m'nyengo yachilimwe ndi nyengo yachisanu kutengera nyengo zomwe zikukulirakulira. Nazi zitsanzo zodziwika bwino:
Udzu Wapachaka wa Chilimwe
Udzu wapachaka wachilimwe umamera m'nyengo yachilimwe kapena kumayambiriro kwa chilimwe, umakula m'miyezi yotentha, ndipo umatulutsa njere zisanafe m'dzinja.
Common Ragweed (Ambrosia artemisiifolia)
Ambrosia artemisiifolia, yokhala ndi mayina odziwika bwino a ragweed, ragweed pachaka, ndi low ragweed, ndi mtundu wamtundu wa Ambrosia wobadwira kumadera aku America.
Amatchedwanso mayina wamba: chowawa cha ku America, bitterweed, blackweed, udzu wa karoti, udzu wa hay fever, chowawa chachiroma, ragweed lalifupi, stammerwort, stickweed, tassel udzu.
Kufotokozera: Ili ndi masamba opindika kwambiri ndipo imatulutsa maluwa ang'onoang'ono obiriwira omwe amasanduka njere ngati burr.
Malo okhala: Amapezeka m'dothi losokonezeka, m'minda, ndi m'mphepete mwa misewu.
Lambsquarters (Chenopodium album)
Albamu ya Chenopodium ndi chomera chomwe chikukula mwachangu pachaka cha banja la Amaranthaceae. Ngakhale kuti mbewuyo imabzalidwa m’madera ena, kwinakwake imatengedwa ngati udzu. Mayina odziwika akuphatikizapo malo a nkhosa, melde, goosefoot, sipinachi wakutchire ndi mafuta-nkhuku, ngakhale kuti awiriwa amagwiritsidwanso ntchito ku mitundu ina ya mtundu wa Chenopodium, chifukwa chake nthawi zambiri amadziwika kuti ndi white goosefoot.Album ya Chenopodium imalima kwambiri Kumpoto kwa India, ndi Nepal monga mbewu yachakudya yotchedwa bathua.
Kufotokozera: Chomera chowongoka chokhala ndi masamba opangidwa ndi mealy, nthawi zambiri chimakhala ndi zokutira zoyera pansi.
Malo okhala: Amakula m'minda, m'minda, komanso m'malo osokonekera.
Pigweed (Amaranthus spp.)
Pigweed ndi dzina lodziwika bwino lamitundu ingapo yogwirizana kwambiri yachilimwe yomwe yakhala namsongole wamkulu wa mbewu zamasamba ndi mizere ku United States komanso padziko lonse lapansi. Nkhumba zambiri zimakhala zazitali, zoimirira mpaka tchire zokhala ndi masamba owoneka ngati oval mpaka diamondi, masamba osinthika, ndi timagulu tamaluwa (masanja amaluwa) okhala ndi maluwa ang'onoang'ono obiriwira. Zimatuluka, zimakula, zimaphuka, zimabzala mbewu, ndipo zimafa mkati mwa nyengo yakukula yopanda chisanu.
Kufotokozera: Zomera zokhala ndi masamba akuluakulu okhala ndi maluwa ang'onoang'ono obiriwira kapena ofiira; zikuphatikizapo mitundu ngati redroot pigweed ndi yosalala pigweed.
Habitat: Zofala m'minda yaulimi komanso dothi losokonezeka.
Crabgrass (Digitaria spp.)
Crabgrass, yomwe nthawi zina imatchedwa udzu wamadzi, ndi udzu waudzu wapachaka womwe umapezeka ku Iowa. Crabgrass imamera m'chaka pamene kutentha kwa nthaka kugunda 55 ° F kwa masiku anayi owongoka ndi usiku, ndipo idzafa ndi nyengo yozizira ndi chisanu mu kugwa. Iowa ili ndi zonse Digitaria ischaemum (crabgrass yosalala, tsinde zosalala zopanda tsitsi zokhala ndi tsitsi pomwe tsinde ndi tsamba zimakumana) komanso Digitaria sanguinalis (crabgrass yayikulu, tsinde ndi masamba ali ndi tsitsi).
Kufotokozera: Chomera chonga udzu chokhala ndi tsinde zazitali, zowonda zomwe zimazika m'malo; ili ndi mitu yambewu ngati chala.
Malo okhala: Amapezeka m’kapinga, m’minda, ndi m’malo aulimi.
Foxtail (Setaria spp.)
Kufotokozera: Udzu wokhala ndi bristly, cylindrical seed heads; zikuphatikizapo mitundu ngati nkhandwe chimphona ndi wobiriwira nkhandwe.
Malo okhala: Ofala m'minda, minda, ndi malo otayira.
Udzu Wapachaka wa Zima
Udzu wapachaka wachisanu umamera m'dzinja, m'nyengo yozizira kwambiri ngati mbande, umakula m'nyengo yachisanu, ndipo umatulutsa mbewu musanafe kumayambiriro kwa chilimwe.
Chickweed (Stellaria media)
Kufotokozera: Chomera chocheperako chokhala ndi maluwa oyera ang'onoang'ono ooneka ngati nyenyezi ndi masamba osalala ozungulira.
Habitat: Imapezeka m'minda, kapinga, ndi malo onyowa, okhala ndi mithunzi.
Henbit (Lamium amplexicaule)
Kufotokozera: Chomera chokhala ndi tsinde lalikulu chokhala ndi masamba opindika komanso maluwa ang'onoang'ono, apinki mpaka ofiirira.
Malo okhala: Amapezeka m'minda, kapinga, ndi dothi losokonezeka.
Bittercress Waubweya (Cardamine hirsuta)
Kufotokozera: Chomera chaching'ono chokhala ndi masamba ogawanika pang'ono ndi maluwa ang'onoang'ono oyera.
Habitat: Imamera m'minda, kapinga, ndi malo achinyezi.
Chikwama cha Mbusa (Capsella bursa-pastoris)
Kufotokozera: Bzalani ndi timbewu tating'onoting'ono, tokhala ngati kachikwama ndi maluwa ang'onoang'ono oyera.
Malo okhala: Ofala m'dothi losokonezeka, minda, ndi m'mphepete mwa misewu.
Bluegrass Yapachaka (Poa annua)
Kufotokozera: Udzu wocheperako wokhala ndi masamba ofewa, obiriwira obiriwira komanso chizolowezi chokulirakulira; imapanga timbewu tating'ono tating'ono, ngati nsonga.
Habitat: Amapezeka mu kapinga, minda, ndi malo ochitira gofu.
Ndi mankhwala otani omwe angagwiritsidwe ntchito kupha udzu?
Mitundu yodziwika bwino ya mankhwala ophera udzu yomwe imagwiritsidwa ntchito pochotsa udzu wapachaka ndiLumikizanani ndi herbicides. (Kodi mankhwala a herbicide ndi chiyani?)
Mankhwala opha udzu ndi mtundu wina wa mankhwala a herbicide omwe amapha magawo a mmera omwe amakumana nawo mwachindunji. Sasuntha (kusuntha) mkati mwa mbewu kuti afike mbali zina monga mizu kapena mphukira. Zotsatira zake, mankhwala ophera udzuwa amagwira ntchito kwambiri pa udzu wapachaka ndipo sagwira ntchito kwambiriosathazomera zokhala ndi mizu yambiri.
Zitsanzo za Kukhudzana ndi Herbicides
Paraquat:
Kachitidwe kake: Imalepheretsa photosynthesis popanga mitundu ya okosijeni yomwe imayambitsa kuwonongeka kwa nembanemba ya cell.
Ntchito: Amagwiritsidwa ntchito kwambiri paulimi poletsa udzu ku mbewu zosiyanasiyana komanso m'malo osalima. Ndiwothandiza kwambiri koma ndi poizoni kwambiri, wofuna kuchitidwa mosamala.
Diquat:
Kachitidwe Kachitidwe: Mofanana ndi paraquat, imasokoneza photosynthesis ndipo imayambitsa kuwonongeka kwa nembanemba ya cell.
Kagwiritsidwe: Amagwiritsidwa ntchito pofewetsa mbewu asanakololedwe, poletsa udzu wam'madzi, komanso kusamalira zomera za m'mafakitale.
Pelargonic acid:
Kachitidwe Kachitidwe: Kusokoneza ma membrane am'maselo kuchititsa kutuluka komanso kufa mwachangu.
Kagwiritsidwe: Zofala paulimi wa organic ndi minda kuti athe kuwongolera udzu ndi udzu. Ndiwopanda poizoni kwa anthu ndi nyama poyerekeza ndi mankhwala opangira udzu.
Kagwiritsidwe:
Mankhwala ophera udzu amagwiritsidwa ntchito pothana ndi namsongole mwachangu komanso moyenera.
Amagwiritsidwa ntchito nthawi yomwe udzu ukufunika mwachangu, monga kubzala musanakolole kapena kuyeretsa minda musanabzale.
Amagwiritsidwanso ntchito m'malo osalima monga malo opangira mafakitale, m'mphepete mwa misewu, komanso m'matauni komwe kumafunikira kuwongolera kwathunthu kwa zomera.
Kuthamanga:
Mankhwala ophera udzuwa nthawi zambiri amagwira ntchito mwachangu, ndipo zizindikiro zowonekera zimawonekera mkati mwa maola ochepa kapena masiku angapo mutagwiritsa ntchito.
Kuwonongeka kofulumira ndi kufa kwa mbali zomera zomwe zalumikizidwa ndizofala.
Kachitidwe:
Kulumikizana ndi mankhwala a herbicides amagwira ntchito powononga kapena kuwononga mbewu zomwe amakhudza. Kusokonezekaku kumachitika kawirikawiri chifukwa cha kusokonezeka kwa membrane, kuletsa kwa photosynthesis, kapena kusokonezeka kwa ma cell ena.
Ubwino:
Kuchita Mwachangu: Kuchotsa mwachangu udzu wowoneka.
Zotsatira Zaposachedwa: Zothandiza pazochitika zomwe zikufunika kuchotsa udzu msanga.
Zotsalira Pang'ono Za Dothi: Nthawi zambiri siziumirira chilengedwe, zomwe zimapangitsa kukhala chisankho chabwino choletsa kubzala udzu.
Ndife asupplier wa udzu wokhala ku China. Ngati simukudziwa momwe mungathanirane ndi udzu, titha kukupangirani mankhwala ophera udzu ndikukutumizirani zitsanzo zaulere kuti muyese. Tikuyembekezera kumva kuchokera kwa inu!
