Kugwa Maluwa Oyera, Kumapiri Amapiri

Kugwa kwa Maluwa a Mitambo ya ku America

Mitengo yamapiri ya ku America yamapiri ( Sorbus americana ) imakula m'madera okwera 3-8 ndipo imatha kufika kutalika mamita makumi atatu, ndi kufalikira komweko. Kugwa kwawo masamba a chikasu. Mtengo wovutawu umapereka chidwi cha masika ndi chilimwe, komanso. Mu kasupe imapanga timango tating'onoting'ono tambirimbiri, maluwa oyera. Maluwawo amapereka fungo loipa , koma amamera ku masango a zipatso zofiira kwambiri m'nyengo yachilimwe.

Zitsanzo zimenezi ndi zachikhalidwe ku East North America ndipo sizitchula za nthaka pH yomwe ikukula. Chomeracho chikukula bwino kwambiri dzuwa lonse. Mwina mungadabwe kumva kuti ndi banja la a rose.

Kugwa Maluwa a Mtengo Woyera

Zomera zonse zomwe zili m'nkhani ino ndi za Fraxinus (mosiyana ndi Sorbus , mtundu umene American mountain ash phulusa uli nawo). Mitengo yambiri ya phulusa ( Fraxinus americana ) ingakulire m'madera 3-9. Awa ndi mtengo wina wotsika kwambiri wa Kumpoto kwa North America. Mitengo yaitali kwambiri kuposa mitengo ya mapiri a ku America, phulusa loyera limakhala lalitali mamita 70, ndi kufalikira komweku. Amakonda dzuwa lonse ndi nthaka yochuluka, koma ngati mitengo ya phulusa yamapiri, imatha kulemera mu dothi ndi ma pH osiyanasiyana. Mitengo ya phulusa yoyera ngati madzi ambiri ndipo imakonda kukhetsa madzi abwino, koma idzalekerera dothi loyera. Masamba a chilimwe ali ndi mdima wobiriwira pamwamba, koma ali ndi mtundu wowala kwambiri pamunsi mwa tsamba - motero dzina lofala.

Kugwa masamba a masamba pa zitsanzo zambiri zimayamba ngati chikasu, kenako zimakhala zofiirira (chithunzi). Amakhala okongola makamaka pamene ali pakati pa siteji: kusakaniza chikasu ndi chofiirira. Komabe, masamba akugwa a phulusa loyera (ndipo fraxinus mtundu wambiri) akhoza kukhala waufupi. Cholakwika china: Muyenera kubzala uyu kutali ndi nyumba kuti mupewe kuwonongeka kwa katundu.

Mapazi a phulusa loyera sali olimba mokwanira kuti athe kulimbana ndi mphepo yamkuntho kapena kusungunuka kwa madzi, ndipo, pamene iwo akuswa, mumafuna kuti iwo asawonongeke pansi (osati pa denga lanu).

A cultivar yakhazikitsidwa kuti adzakhala ochepa kwambiri (yofunika kuganizira ang'onoang'ono yards). Amatchedwa 'Purple Purple,' imakula mpaka kufika mamita 45 mpaka 60 kutalika, ndi kufalikira kwa mamita 35-50.

Mitundu Yina ya Fraxinus (ndi Yomwe Ili Ndi Zonsezi Zina mwa Mayina Amodzi?)

Mitundu ina ya Fraxinus imakhumba zikhalidwe zomwe zikukula ndipo zimapezeka m'nkhalango zingapo padziko lapansi, monga:

1. Phulusa loyera ( Fraxinus pennsylvanica lanceolata )
2. Phulusa lofiira ( Fraxinus pennsylvanica pennsylvanica )
3. Phulusa lakuda ( Fraxinus nigra )
4. Phulusa la Buluu ( Fraxinus quadrangulata )
5. Phulusa la ku Ulaya ( Fraxinus excelsior )

Phulusa lakuda limapezeka kumpoto kwa America ndipo limakula m'madera odzala USDA 3-9. Lili ndi masamba omwe amagwa. Chitsanzochi, pa msinkhu, chimatha kukhala wamtali ngati mamita makumi asanu, ndi kufalikira mozama ngati mamita 50. Mitundu yofiira ndi yakuda imayendera miyeso yofanana ndikukula kudera limodzi la USDA; masamba a mitengo iyi ya ku America, nawonso amasanduka chikasu.

Phulusa lamtundu wakuda ndi lalikulu ngati mapulusa ena a kumpoto kwa America koma osati ozizira kwambiri (owerengedwa ku gawo lachinayi).

Dzina lake la mtundu, quadrangulata limatchula kuti nthambi zatsopano zimayambira mofanana. Sitikudziwitse mtundu wa mtundu umene ukuyenera kutchulidwa, malinga ndi Dipatimenti ya Zamalonda ya Ohio (Forestry Division) ya Ohio.

Mwinamwake mwazindikira kuti zina mwa zomera izi zapatsidwa mayina omwe amasonyeza mtundu. Monga tafotokozera pamwambapa, phulusa "loyera" limatchedwa chifukwa cha kuwala kwa masamba ake pansi (poyerekeza ndi nsonga). Nanga bwanji za mitundu yakuda, yofiira, yobiriwira, ndi ya buluu? Eya, malingana ndi The Friends of the Wild Flower Garden, woyamba adatchedwa "wakuda" chifukwa cha mdima wa masamba ake. Mofananamo, Illinois Wildflowers amawona kuti nthambi zazing'ono za phulusa lofiira zimakhala ndi mtundu wobiriwira, choncho izi mwina zimachokera ku dzina lofala. Pakalipano, mtundu wa "wobiriwira" ukuwoneka kuti walandira dzina lake lomwelo mwachisawawa.

Ndipotu, mbali ziwiri za masamba ake ndi mthunzi wobiriwira, kotero "zobiriwira" zikuoneka kuti ndizo dzina loti lizigwiritsa ntchito posiyanitsa ndi phulusa loyera. Chiyambi cha dzina la mtundu wa "buluu" ndi chochititsa chidwi kwambiri pa gawoli: Chowonadi n'chakuti wina akhoza kuthetsa dothi la buluu ku mtengo uwu.

Pa mapulusa onse, ndi phulusa la European ( Fraxinus excelsior ) lomwe limatchuka kwambiri mu mabuku (ngakhale, monga phulusa la buluu, mtundu wa kugwa ndi wosasangalatsa). Zimphonazi zikhoza kukulira kufika kutalika mamita 100, ndi kufalikira komweku. Mu nthano za Norse, mtengo wina wa ash ash wa ku Ulaya wotchedwa "Yggdrasil" umathandizira chilengedwe chonse. Koma monga momwe milungu yachi Norse idzawonongedwera pomaliza ku adani awo, Giants, kotero ngakhale mtengo uwu sungatheke. Njoka yoopsya imathamanga pazu wake mu Niflheim, ndipo tsiku lina phulusa lalikulu lidzagwa pansi-ndipo, pamodzi ndi ilo, chilengedwe.

Mtundu wa Fraxinus uli m'banja la azitona.

Emerald Ash Borers: Njira Zogwiritsira Ntchito

Tizilombo toyambitsa matendawa, omwe amadziwika kuti Agrilus planipennis ndi mbadwa za ku Asia, ndilo tizilombo towononga kwambiri mitengo ya phulusa ya ku North America. Ndi mphutsi zomwe zimawononga kwambiri. Ogwira ntchito yoteteza zachilengedwe akuyesetsa kwambiri kuti asamayang'ane phulusa la emerald. Kawirikawiri amakumana ndi misampha yomwe imayikidwa m'mayipi kuti ayese kuyendetsa tizilombo. Njira zina zowononga ndi izi:

1. Tizilombo toyambitsa matenda
2. Tizilombo toyambitsa matenda ("predaceous and parasitic tizilombo, tizirombo ta tizilombo, ndi timatabwa ta mitengo," malinga ndi USDA Forest Service)
