Chinachake pafupifupi zamatsenga chimachitika kugwa kulikonse. Ndi chiyani? Uku ndikusintha kwamtundu wamasamba pamitengo. Ena mwa mitengo yokongola kwambiri yophukira:
- mapulo;
- mtedza;
- kuluma;
- mtengo.
Mitengo iyi (ndi mitengo ina iliyonse yomwe imasiya masamba) amatchedwa mitengo yazipatso.
Nkhalango zowuma
Mtengo wosasunthika ndi mtengo womwe umatulutsa masamba mu kugwa ndikumera yatsopano mchaka. Chaka chilichonse, mitengo yodula imadutsa pomwe masamba ake obiriwira amasintha kukhala achikaso, golide, lalanje komanso kufiyira kwa milungu ingapo isanakhale yofiirira ndikugwa pansi.
Masamba ndi chiyani?
Mu Seputembala, Okutobala ndi Novembala timasangalala ndikusintha kwamtundu wamasamba amtengo. Koma mitengoyo siyimasintha mtundu, chifukwa chake muyenera kudziwa chifukwa chake masamba amasanduka achikasu. Pali chifukwa chake mitundu yosiyanasiyana imagwa.
Photosynthesis ndiyo njira yomwe mitengo (ndi zomera) imagwiritsira ntchito "kuphika chakudya." Kutenga mphamvu kuchokera padzuwa, madzi kuchokera pansi, ndi carbon dioxide kuchokera mlengalenga, amasintha shuga (shuga) kukhala "chakudya" kuti athe kukula kukhala zomera zolimba, zathanzi.
Photosynthesis imapezeka m'masamba a mtengo (kapena chomera) chifukwa cha chlorophyll. Chlorophyll imagwiranso ntchito ina; amasintha masamba kukhala obiriwira.
Nthawi komanso chifukwa chiyani masamba amasanduka achikasu
Chifukwa chake, bola masambawo atenge kutentha ndi mphamvu zokwanira kuchokera padzuwa kuti azidya, masambawo amakhala obiriwira. Koma nyengo ikasintha, kumazizilitsa m'malo omwe mitengo imakula. Masiku akufupikitsa (pang'ono dzuwa). Izi zikachitika, zimakhala zovuta kwambiri kuti chlorophyll m'masamba azikonzekera chakudya chofunikira kuti chikhalebe chobiriwira. Chifukwa chake, m'malo mopanga chakudya chochuluka, masambawo amayamba kugwiritsa ntchito michere yomwe adasunga m'masamba m'miyezi yotentha.
Masamba akamagwiritsa ntchito chakudya (shuga) chomwe chadzikundikira, timaselo tating'onoting'ono timapanga m'munsi mwa tsamba lililonse. Maselowa ndi oterera ngati kork. Ntchito yawo ndikukhala ngati khomo pakati pa tsamba ndi mtengo wina wonse. Chitseko ichi chatsekedwa pang'onopang'ono "ndikutseguka" mpaka chakudya chonse kuchokera kutsamba chatha.
Kumbukirani: chlorophyll amapanga zomera ndikusiya zobiriwira
Munthawi imeneyi, mitundu yosiyanasiyana imawonekera pamasamba a mitengo. Mitundu yofiira, yachikaso, golide ndi lalanje imabisala m'masamba nthawi yonse yotentha. Siziwoneka m'nyengo yotentha chifukwa cha kuchuluka kwa ma chlorophyll.
Nkhalango zachikasu
Chakudya chonse chatha, masamba amasanduka achikasu, amasanduka bulauni, amafa ndikugwa pansi.
