Kodi evaporation mbewu? Kodi chimayambitsa zodabwitsazi?

Ambiri a anthu a aukira kufunika kwa zomera moyo pa dziko. Nthawiyi, ndicho zomera kupereka kubwezeretsa oxygen a Dziko Lapansi, herbivore chakudya ndi zina moyo, zinyalala kwachilengedwenso akonzanso mpweya.

Ndipo ngakhale madzi mkombero mu chikhalidwe ndi zodabwitsa popanda zomera ndi! Inu mukudziwa kufunika kwa evaporation zomera, ndi biosphere wonse? Ngati sichoncho, ndiye inu takonzekera nkhaniyi!

Monga madzi amalowa minofu ndi zomera maselo?

Kupyolera mizu ndi muzu tsitsi la madzi imatsala, ndipo kenako kufalikira mu thupi la mbewu. Monga momwe zinalili ndi maselo nyama, madzi - moyo komanso minofu chomera oposa 90% ya izo kwa madzi.

Mamolekyulu salt zambiri za kufufuza zinthu zimene kusungunuka mu madzi, ndi kuthamanga ena pa khungu nembanemba, monga kudutsa mu bwinobwino zinthu sindingakhoze.

zodabwitsazi amatchedwa osmotic anzawo. Kumene, madzi wokha mu mawonekedwe a njira isotonic salt komanso akutambasula nembanemba kusintha selo. voteji lasonyezedwa ndi mawu akuti "turgor". Mwachidule, ndi chifukwa madzi ndi mchere chomera minofu anakhalabe mu boma zotanuka ndi zotanuka. Koma izi zimachitika yekha pansi zinthu zachilendo kagayidwe madzi amchere.

Kotero kufunika kwa evaporation mbewu? Kamodzi madzi ukuphwera ku selo ndende salt m'menemo amakhala akuluakulu. Yankho kuikapo maganizo amayamba kukoka madzi selo nembanemba bola ngati sudzatha isotonic. Kusiyana woipa mchere mu chipinda ndipo madzi amene akulowa chomera ndiyo mphamvu ya suction.

Kufunika evaporation mu ndondomeko

Pamwamba pa pepala la obowoka ting'onoting'ono stomata. Ndi thandizo lawo chomera wotaya chinyezi kuchokera pamwamba pake. Ndipo kodi ndi evaporation chomera mu nkhani iyi? Koposa zonse, popeza ndi chifukwa evaporation ndi kukula mchere ndende muchipindachi analenga suction mphamvu kulimbikitsa otaya madzi ndi zakudya maselo zimakhala.

Ndipotu, onse a kayendedwe ka madzi mu mbewu zimatheka chifukwa ndondomeko evaporation. Sikuti kukhulupirira kuti zodabwitsazi ndi kulamulira: tsamba stomata akhoza kutsegulidwa ndi kutsekedwa pa nusu peresenti ndi, mwangwiro kusintha mphamvu ya kusintha chinyezi mu chilengedwe. Mu mdima, ndipo masana dzuwa, iwo kwathunthu alipo, kuteteza zomera madzi m'thupi.

Kumene atamu- ingress madzi mu cytoplasm maselo

Ngati mphamvu ya kayendedwe ka madzi mu zimakhala za mbewu ankadalira kokha evaporation, ilo kwathunthu anasiya usiku. chakuti madzi ukuphwera kudzera cuticle nthawizonse, koma kuchuluka kwake ndi laling'ono kwambiri.

Ngati mumathera chokuchitikira basi, kudula chomera pambali kolala muzu, muona mwamsanga kuti madzi akupitirizabe kuyenda kuyambira kumizu. Izi zikusonyeza kuti chimachititsanso madzimadzi kudzera minofu chomera ndi chifukwa kusiyana kwa woipa njira.

Komanso, mbali yaikulu mu ndondomeko imeneyi ndi muzu kuthamanga, chifukwa chimene chomera chimaposa chinyezi mu "ziwiya", popangidwa ndi zigawo maselo a khungu akufa.

Popeza zimakhala moyo palibe, madzi ndi mtima wonse adza kwa tsamba mwa stomata kumene evaporation tatchulazi.

Kotero kufunika kwa evaporation mbewu, ngati inu kusonkhanitsa mfundo zonse? Choyamba, kuyenda chifukwa cha zodabwitsazi wa madzi kupyolera mu mmera kufala zakudya. Chachiwiri, evaporation zonse n'kofunika kwambiri zomera kukula mu madera kum'mwera. Evaporating madzi akamazizira chomera lonse banal.

Monga mukuonera, ndi evaporation madzi zomera amachita mbali yofunika kwambiri.

Kuchuluka chinyezi mayamwidwe ndi chamunthuyo

Losavuta zatsopano asayansi asonyeza kuti zikwi mbali ndi buku la madzi analandira ndi chomera kudya palibe zoposa zitatu. winayo 997 mbali zonse ndi kulemera kwa evaporating. Zomera wathu nyengo amafuna za madzi kilogalamu asanduke nthunzi kupanga kuchuluka ofanana pa nkhaniyi youma. Mwachidule, mphamvu ya zodabwitsazi zimadalira mmene nyengo m'dera lanu.

Zimene asayansi

Scientist Shlessing angapo zaka zapitazo, unachitikira chokuchitikirani zimasangalatsa. Iye adakwata atatu chitsamba fodya, awiri amene anabzala mu nthaka lotseguka. Kusiyana pakati pa iwo anali kokha mu zikuchokera nthaka ndi ikamatera malo. A chomera wachitatu mizu mumphika, zomwe zinali mu zikhalidwe chipinda, koma nthawi zonse yokutidwa ndi nyumba ndi.

Chifukwa cha zatsopano wake, anapeza kuti poyamba tchire ziwiri zomera zonse chamunthuyo pafupifupi katatu madzi ambiri, koma aumbike mwa awiri (!) Times nkhani zochepa youma, osati "chipinda" fodya.

Koma! Pamene anawatentha woyamba awiri zomera, ndi anadabwa ndinazindikira kuti zinthu mchere iwo ali ndi nthawi theka. Choncho, ambabzala evaporation mokwanira amphamvu chinyezi makamaka m'madera otentha louma kapena nyengo, kumabweretsa kupanga owonjezera zinthu mchere, kuti iwo kwenikweni osafunika.

Kufunika evaporation mu moyo wa mbewu

Izi ndi zoona makamaka mbewu. Mwazina, zodabwitsazi komanso kumachepetsa kufunika zakudya ndi kulawa iwo, chifukwa owonjezera phulusa zinthu zoipa amakhudza Chiwerengerochi. Choncho, kuchuluka evaporation madzi kumathandiza kuti mbewu ngakhale aakulu zikutha m'mayiko dothi, monga mchere ambiri kutali kwa izo.

N'chifukwa chiyani ndikukuuzani inu zonsezi? osati aliyense akumvetsa izo zonse mu chikhalidwe chiri cholukanalukana. Sichangozi kuti kumadera otentha dothi chofunika manyowa zambiri. Komanso, m'madera amenewa kumene kukhala tcheru ndi kugwiritsa ntchito feteleza mchere, amene ayenera kuonedwa mu chitukuko cha makhalidwe akatswiri ulimi wa kulima mbewu zosiyanasiyana.

Impact kukoma ndi zakudya khalidwe la zomera

Komabe, mbewu obereketsa akhala Kale anazindikira kuti zaka youma, pamene zomera kuti zonse kuthirira kupatsa thanzi akutsikira zikuchepa poyerekeza ndi wabwino mwa mawu a zaka mvula. Choncho, moyo evaporation mbewu n'chofunikira wokulirapo kuposa angaganize kuchokera kunja.

N'zosadabwitsa kuti mu zaka makamaka otentha, pamene kuchuluka kwa chinyontho m'nthaka ndi yokhudza ufiti yafupika ndi luso evaporative akutsikira asatayike, kukula ndi chitukuko cha zomera inatsala pang'ono. Mu zinthu izi, iwo sangathenso kuziziritsa yokha, koma chifukwa nthawi zambiri banal youma.

anapezazo

Ngakhale milandu ofatsa yochepa chilala chifukwa cha ichi pa masamba msanga kuoneka zilonda zamoto. Izi makamaka kutchulidwa kumadera amenewo pamene pali mphepo, kuti ali otentha ndi youma kwambiri mphepo.

Ngati palibe kanthu akutengedwa, ndiye zochitika izi nyengo mosavuta kuwononga ngakhale dera lonse ndi kulima. Ndinangoganiza akulima ulimi yake ndi ulamuliro udzu akhoza kupulumutsa zokolola. Komabe, anthu amadziŵa zimenezi ndi nthawi yayitali.

Tikukhulupirira, tsopano ife kukhulupirira kuti evaporation zomera - ndondomeko zofunika, popanda zomwe iwo sangathe adalipo.
