Zotsatira za kapangidwe ka ulusi pa makhalidwe a zamkati ndi ubwino wake

Mu makampani opanga mapepala, mawonekedwe a ulusi ndi chimodzi mwazinthu zofunika kwambiri zomwe zimatsimikiza mawonekedwe a pulp ndi mtundu womaliza wa pepala. Mawonekedwe a ulusi amaphatikizapo kutalika kwapakati kwa ulusi, chiŵerengero cha makulidwe a khoma la ulusi ndi m'mimba mwake wa selo (chomwe chimatchedwa chiŵerengero cha khoma ndi m'mimba), ndi kuchuluka kwa ma heterocyte osakhala a ulusi ndi ma bundle a ulusi mu pulp. Zinthu izi zimagwirira ntchito limodzi, ndipo zimakhudza pamodzi mphamvu yomangirira ya pulp, mphamvu yosowa madzi m'thupi, magwiridwe antchito okopera, komanso mphamvu, kulimba ndi mtundu wonse wa pepala.

1) Utali wapakati wa ulusi
Utali wapakati wa ulusi ndi chimodzi mwa zizindikiro zofunika kwambiri za ubwino wa ulusi. Ulusi wautali umapanga unyolo wautali wa netiweki mu ulusi, zomwe zimathandiza kulimbitsa mphamvu ya mgwirizano ndi mphamvu zomangika za pepala. Utali wapakati wa ulusi ukawonjezeka, kuchuluka kwa mfundo zolukana pakati pa ulusi kumawonjezeka, zomwe zimathandiza kuti pepalalo lifalikire bwino likakumana ndi mphamvu zakunja, motero kulimbitsa mphamvu ndi kulimba kwa pepalalo. Chifukwa chake, kugwiritsa ntchito ulusi wautali wapakati, monga ulusi wa spruce coniferous kapena ulusi wa thonje ndi nsalu, kungapangitse kuti pepala likhale lolimba kwambiri, ndipo mapepalawa ndi oyenera kugwiritsidwa ntchito pofunikira zinthu zakuthupi, monga zinthu zopakira, mapepala osindikizira ndi zina zotero.
2) Chiŵerengero cha makulidwe a khoma la ulusi wa selo ndi m'mimba mwake wa selo (chiŵerengero cha khoma ndi dzenje)
Chiŵerengero cha khoma ndi khola ndi chinthu china chofunikira chomwe chimakhudza makhalidwe a pulp. Chiŵerengero chotsika cha khoma ndi khola chimatanthauza kuti khoma la selo la ulusi ndi lochepa ndipo khola la selo ndi lalikulu, kotero kuti ulusi womwe umagwiritsidwa ntchito popanga mapepala ndi kupanga mapepala ndi wosavuta kuyamwa madzi ndi kufewa, zomwe zimathandiza kuti ulusiwo ukhale wosalala, utuluke komanso ulumikizane. Nthawi yomweyo, ulusi wopyapyala umapereka kusinthasintha bwino komanso kupindika bwino popanga mapepala, zomwe zimapangitsa kuti pepalalo likhale loyenera kwambiri pokonza ndi kupanga mapepala ovuta. Mosiyana ndi zimenezi, ulusi wokhala ndi chiŵerengero chachikulu cha khoma ndi khola ukhoza kuyambitsa pepala lolimba kwambiri komanso losalimba, lomwe silingathandize kukonza ndi kugwiritsa ntchito pambuyo pake.
3) Kuchuluka kwa ma heterocyte osalimba ndi ma fiber bundles
Maselo osakhala ndi ulusi ndi ma ulusi m'mapepala ndi zinthu zoipa zomwe zimakhudza ubwino wa pepala. Zonyansa zimenezi sizingochepetsa kuyera ndi kufanana kwa mapepala, komanso njira yopangira mapepala kuti apange mfundo ndi zolakwika, zomwe zimakhudza kusalala ndi mphamvu ya pepala. Ma heterocyte osakhala ndi ulusi angachokere ku zinthu zopanda ulusi monga makungwa, utomoni ndi chingamu mu zinthu zopangira, pomwe ma ulusi ndi ma fiber aggregates omwe amapangidwa chifukwa cha kulephera kwa zinthu zopangira kugawanika mokwanira panthawi yokonzekera. Chifukwa chake, zonyansa izi ziyenera kuchotsedwa momwe zingathere panthawi yopangira mapepala kuti ziwongolere ubwino wa mapepala ndi kuchuluka kwa mapepala.
