Mafakitale ambiri amasankha kugwiritsa ntchito nkhuni zoteteza paini ngati zopangira nyumba ya cubby, koma sakudziwa chifukwa chake.Kenako, ndifotokoza mbali zitatu.
Makhalidwe a sycamore pine:
Pinus sylvestris (Pinus sylvestris var. mongolica Litv.) ndi mtengo wobiriwira nthawi zonse, wa mamita 15-25 m’litali, kufika mamita 30 m’mwamba, wokhala ndi korona wozungulira kapena wozungulira.Thunthulo ndi lowongoka, khungwa lomwe lili pansi pa 3-4 mita ndi lakuda-bulauni, lopindika komanso lopindika kwambiri, masamba ndi singano 2 pamtolo, olimba, nthawi zambiri amapindika pang'ono, ndipo nsonga yake ndi yolunjika.Monoecious, ma cones amphongo ndi oval, achikasu, ophatikizidwa kumunsi kwa nthambi za chaka chino;ma cones achikazi ndi ozungulira kapena oval, ofiirira-bulauni.Ma cones ndi ovate.Chishango cha sikelo ndi chooneka ngati rhombus, chokhala ndi zitunda zazitali komanso zopingasa, ndipo squamous umbilicus ndi chotupa ngati chotupa.Mbewu ndi zazing'ono, zachikasu, zofiirira, ndi zofiirira, ndi mapiko a membranous.Amapangidwa m'mapiri a 400-900 mamita pamwamba pa nyanja m'mapiri a Daxinganling ku Heilongjiang, China ndi mchenga wa mchenga kumadzulo ndi kumwera kwa Hailar.Itha kugwiritsidwa ntchito ngati munda wokongola komanso wobiriwira mitundu yamitengo.Mitengoyi imakula mwachangu, yokhala ndi zinthu zabwino komanso yosinthika mwamphamvu, ndipo itha kugwiritsidwa ntchito ngati mitengo yamitengo m'mapiri a Daxinganling kumpoto chakum'mawa kwa China ndi milu ya mchenga kumadzulo.
Pinus sylvestris ndi mtengo wabwino kwambiri wamitengo yomwe imakula mwachangu, kubiriwira koteteza, kuteteza nthaka ndi madzi kumpoto chakum'mawa kwa China.Zinthuzo ndi zamphamvu ndipo mawonekedwe ake ndi owongoka, omwe angagwiritsidwe ntchito pomanga, mipando ndi zipangizo zina.Thunthu likhoza kudulidwa kuti lipange utomoni, mapeyala a pine ndi turpentine akhoza kuchotsedwa, ndipo khungwa likhoza kuchotsedwa.
Mtengowo ndi wofiirira wofiirira, mtengo wa sapwood ndi wofiirira, ulusi wake ndi wowongoka, njere zake ndi zowongoka, ndipo pali utomoni.Itha kugwiritsidwa ntchito pomanga, ogona, mizati, zombo, zida, mipando ndi matabwa CHIKWANGWANI mafakitale zipangizo.Thunthu limatha kudulidwa chifukwa cha utomoni, rosin ndi turpentine zitha kuchotsedwa, ndipo khungwa limatha kuchotsedwa ku tannin.Itha kugwiritsidwa ntchito ngati munda wokongola komanso wobiriwira mitundu yamitengo.Mitengoyi imakula mwachangu, yokhala ndi zinthu zabwino komanso yosinthika mwamphamvu, ndipo itha kugwiritsidwa ntchito ngati mitengo yamitengo m'mapiri a Daxinganling kumpoto chakum'mawa kwa China ndi milu ya mchenga kumadzulo.[1]
Kuchuluka kwa mpweya wowuma 422kg/m3;nkhuni kuuma ndi kachulukidwe ndi zolimbitsa, thupi katundu index ndi zolimbitsa, kugwira mphamvu ndi zolimbitsa;mawonekedwe ake ndi abwino komanso owongoka, njere zamatabwa zimamveka bwino, ma deformation coefficient ndi ochepa;kuyanika, kukonza makina, odana ndi dzimbiri ntchito mankhwala ndi zabwino;ntchito yopaka utoto ndi yolumikizira ndi avareji.Zosavuta kupenta ndi kuipitsidwa pambuyo posungidwa.Ndiwopangira matabwa aku China odana ndi dzimbiri, ndipo zinthu zazitali kwambiri nthawi zambiri zimakhala 6 mita.
Maonekedwe a mtengo ndi thunthu ndi zokongola, ndipo zingagwiritsidwe ntchito ngati mitengo yokongoletsera m'munda ndi yobiriwira.Chifukwa cha kuzizira kwake, kukana chilala, kusabereka komanso kukana mphepo, itha kugwiritsidwa ntchito ngati mtengo waukulu wamitengo yosungiramo nkhalango komanso nkhalango zokonza mchenga m'magawo atatu aku North North.Pambuyo pa mitengo yamitengo mumchenga kupulumuka, ndi kukula kwa mitengo, osati kukokoloka kwa mphepo kumachepetsedwa, koma zinyalala zimawonjezeka, ndipo zimakhala ndi zotsatira zolepheretsa mphepo ndi mchenga ndi kusintha chilengedwe.
Makhalidwe a matabwa oteteza:
Mitengo yodzitetezera imapangidwa powonjezera zinthu zoteteza mankhwala ku nkhuni wamba kuti zikhale zotsutsana ndi dzimbiri, zotetezedwa ndi chinyezi, zisawonongeke ndi bowa, zoteteza tizilombo, mildew-proof ndi madzi.Pali zida ziwiri zazikuluzikulu zamatabwa otetezedwa ku China: pine waku Russia ndi Nordic red pine.Ikhoza kukhudzana mwachindunji ndi nthaka ndi chilengedwe chachinyontho, ndipo nthawi zambiri imagwiritsidwa ntchito pansi panja, mapulojekiti, malo, malo odana ndi matabwa amaluwa, ndi zina zotero, kuti anthu apume ndikusangalala ndi kukongola kwachilengedwe.Ndizinthu zabwino kwambiri zapansi panja, malo am'munda, masinthidwe amatabwa, malo osangalatsa, matabwa amatabwa, etc.
Kuphatikiza zopangira zapamwamba kwambiri ndi mankhwalawa odana ndi dzimbiri zitha kuonetsetsa kuti zinthu zili bwino momwe mungathere.
