Zithunzi za Ragweed

Zithunzi zanga za ragweed zidzakuthandizani kuzindikira chomera chimene anthu ambiri amalankhula, ngakhale kuti sadziwa kwenikweni chomwe chikuwoneka. Chifukwa chimene udzu umayambira pa zokambirana ndi m'nkhani zambiri kawirikawiri ndikuti ndizomwe zimayambira ku North America. Koma n'chifukwa chiyani anthu ali ndi vuto lalikulu pozindikira chomera chomwe chimakhudza kwambiri anthu?

Ndizomveka kuti oyamba kumene akudziwitsidwa za mbewu adzakhala ndi vuto lozindikiritsa udzu uno. Tayang'anani pa chithunzi chomwe chili pa tsamba lino, chomwe chimapereka maso a mbalame pamaso a ragweed wamba . Ziri ngati nondescript namsongole momwe mungapezere mmunda. Palibe zipatso zokongola monga momwe zilili, mwachitsanzo, nightshade . Ngakhale pamene pachimake, maluwa ake amangofuna kukhala ndi khalidwe la maluwa a dandelion .

Koma mavuto ndi chizindikiritso sali ochepa chabe. Nthawi ina ndinapita kumunda wautchire wa August ndi mkazi (tiyeni timuimbire Wildflower Wilma) yemwe anali pafupi kwambiri ndi zomera za malo ano monga aliyense angakhalire. Iye anachotsa dzina la zomera pambuyo pa dzina la zomera pa ulendowu, ndi chitsimikizo cha wina yemwe anali kwathunthu m'nkhalango. Koma ndikuyenera kuvomereza kuti ndinadabwa pomwe, kumapeto kwa ulendowu, Wildflower Wilma ananyamula chomera cha mugwort ( Artemisia vulgaris ) ndipo adachizindikira kuti ndi "ragweed."

Palibe amene amadziwa zonse, ndithudi. Ndipo ndikuganizira mozama, ndinatha kumumvera chisoni, pamtundu wina, mwachinsinsi chake: ngati chomera chilichonse chingathe kutsutsana ndi mutu wachitsamba chodetsedwa, ndi mugwort. Mwina ndi koyenera kudziwa kuti botanical dzina lofala ragweed ndi Ambrosia artemisiifolia . Chidziwitso chake chapadera ndi chizindikiro chakuti anthu awona kufanana pakati pawo ndi ena a mtundu, Artemisia (mwachitsanzo, Silver Mound artemisia ), yomwe mugwort ndi yake.

Chiyembekezo changa n'chakuti, mutatha kuwona zithunzi zanga za ragweed pamasamba asanu ndi awiri, mutha kuchita zomwe ngakhale mphukira ya wathanzi Wilma sakanakhoza kuchita: kutanthauza, kuzindikira, mosakayikira, udzu umene wabweretsa mavuto kwa mamiliyoni osawerengeka odwala matenda opatsirana.
