Phulusa ndi lokhazikika komanso losavuta kusweka ndi kupunduka. Ndizinthu zabwino kwambiri zopangira mipando. Koma ndizovuta kwa ogula kunena zoona kuchokera zabodza! Choncho, pali ochepa Manchurian Phulusa pamsika tsopano, ambiri a iwo ndi Russian phulusa ndi American mphutsi. Ngakhale kuti ndi yofanana ndi phulusa la zinthu, mtengo wake ndi wochepa kwambiri kuposa wa kumpoto chakum'mawa kwa Fraxinus mandshurica. Zitha kuwoneka kuchokera ku njere zamatabwa. Tiyenera kufananiza zambiri.

Kuipa kwa mipando ya Ash:

1. Mipando yamatabwa ya phulusa imakhala ndi mapindikidwe akulu. Amapangidwa ndi matabwa olimba. Nthawi zambiri amaphatikiza ndi timitengo tating'onoting'ono. Mitengo ikuluikulu imachepa ndipo imapunduka kwambiri, zomwe sizoyenera. Kuyenera kudziŵika kuti ena Fraxinus mandshurica mipando kwenikweni olimba matabwa a Fraxinus mandshurica mu chimango chachikulu, ndi mbali yaikulu ya izo ndi olimba nkhuni veneer wa Fraxinus mandshurica, amenenso chifukwa cha mapindikidwe lalikulu ndi chidule cha Fraxinus mandshurica.

2.Ash nkhuni alibe heartwood anti-corruption mphamvu. Tiyenera kukumbukira kuti nkhuni zoyera ndizosavuta kudyedwa ndi kafadala za ufa ndi tizilombo tating'onoting'ono, zomwe sizimawuma mosavuta, komanso zimatha kugwedezeka.

Ubwino wa mipando ya Ash:

1. Kukonzekera kwa matabwa a Phulusa: ntchito yopangira phulusa ndi yabwino, imatha kukhomedwa ndi kukonzedwa mosavuta, imakhala yolimba kwambiri, ndipo zomangira ndi guluu zimakhazikika bwino.

2. Kukhalitsa kwa nkhuni za phulusa: Heartwood imakhala ndi mphamvu yapakati yolimbana ndi dzimbiri, pamene nkhuni zoyera (sapwood) zimakhala ndi mphamvu. Mitengo ya phulusa ndi yoyenera kwambiri nyengo youma, kukalamba kwake kumakhala kochepa kwambiri, ndipo mtima wake umasintha pang'ono.

3. Gawo la phulusa la nkhuni ndi losalala kwambiri, lokhala ndi kusiyana kochepa kwa mtundu, kukana kwa dzimbiri, kukana madzi abwino, maonekedwe abwino a utoto, utoto wabwino ndi kugwira ntchito. Ikhoza kupakidwa utoto ndi kupukutidwa kuti ikhale yabwino pamtunda ndi ntchito yabwino yokongoletsera.

4. Fraxinus mandshurica ali ndi zinthu zolimba, mawonekedwe okongola, mphamvu zabwino zonse, kukana kwa chivomezi komanso mphamvu yopindika ya nthunzi, ndipo ndi chinthu chabwino chopangira mipando.

ndi yabwino, imatha kukhomeredwa ndikukonzedwa mosavuta, imakhala yolimba kwambiri, ndipo zomangira ndi guluu zimakhazikika bwino.

2. Kukhalitsa kwa Fraxinus mandshurica: Heartwood ili ndi kukana kwapakatikati kwa anti-corrosion agent, pamene nkhuni zoyera (sapwood) zimakhala ndi permeability. Fraxinus mandshurica ndi yoyenera kwambiri nyengo youma, ukalamba wake ndi wochepa kwambiri, ndipo mtima wake umasintha pang'ono.

3. Gawo la phulusa la nkhuni ndi losalala kwambiri, lokhala ndi kusiyana kochepa kwa mtundu, kukana kwa dzimbiri, kukana madzi abwino, maonekedwe abwino a utoto, utoto wabwino ndi kugwira ntchito. Ikhoza kupakidwa utoto ndi kupukutidwa kuti ikhale yabwino pamtunda ndi ntchito yabwino yokongoletsera.

4. Mitengo ya phulusa ili ndi zinthu zolimba, maonekedwe okongola, mphamvu zabwino zonse, kukana kwa chivomezi komanso mphamvu yopindika ya nthunzi, ndipo ndi chinthu chabwino chopangira mipando.
