Ahamiyati rastanii sabz dar tabiat va hayoti inson

Olimi barjastai rus Kliment Arkadevich Timiryazev dar “Hayoti rastani” nom kitobash dar khususi ahamiyati rastanihoi sabz dar tabiat va inkishofi hayot dar rui Zamin ba tavri khele vozehu fah- mo khitob kardaast: “Zamone, dar kadom yak mahal nuri Oftob ba Zamin aftid, ammo na ba zamini besamar, balki ba yak maysai sab- zi gandum yo anikdarash ba donai khlorofill. Nur ba dona barkhur du khomush shud, hamchun rushnoi barham khurd, ammo nest nashud. Vay faqat baroi ijroi kori dokhily sarf shud…”

Hamin tavr, rastanii sabz hangomi fotosintez energiyai nuri Oftobrs az khud mekunad va moddahoi organiki hosil karda, oksigen khorij mekunad. Rastani az moddahoi organiki gizo girifta mesabzad, gul mekunad va dar -on meva va tukhm pukhta merasad. Hay- vonot va odam moddahoi organikii dar rastaniho hosilshudaro is- temol mekunand. Be mavjudiyati rastanihoi sabz mavjudoti zindai Zamin be khuroku gizo memond.

Rastanihoi sabz atmosferaro az oksigen, ki baroi nafasgirii hamai organizmhoi zinda zarur ast, boy megardonand. Gazi karbo- nati havoro furu burda, havoro toza mekunand. To on dame, ki dar rui Zamin rastanihoi sabz vujud dorand, zakhirai oksigen tamom nameshavad.

Besha, margzor, dashtu domanakuh va digar nohiyaho bo rasta- nihoyashon mahalli zisti hayvonot meboshand. Hayvonot dar in mahalho hayot ba sar burda, khurok meyoband, panoh mebarand va ba- roi afzoish sharoit paydo mekunand. Ba har kadom anbuhi nabo- tot guruhi muayyani hayvonot muvofiqati zisti dorand.

Ahamiyati rastanihoi sabz dar hayoti inson beandoza kalon ast. Rastaniho hamchun manbai oksigeni havo va gizoi organiki ba hisob rafta, insonro inchunin bo suzishvori, masolekhi binokori va ashyoi khomi sanoati tamin megardonand. Inson hatto ba sifati suzishvori boqimondahoi on rastanihoero istifoda mebarad, ki hazorho va millionho sol pesh nashunamo doshtand. Masalan, angishtsang va torf.

Hususan, kuchavu khiyobonho, chorbogu gulbogho va gulgashthoi sabzu khurramro be rastani tasavvur kardan az imkon berun ast. Ras- taniho changu gard va digar guboru gashhoi baroi salomati zarar- nokro furu burda, havoro az iflosshavy emin nigoh medorand.

Rastaniho namnokii mutadili havoro nigoh doshta, shiddati galo- gulavu shavqunro dar kuchahoi shahr past mekunand, peshi rohi shamoli sakht va buroni khokbodro megirand. Binobar on, odamon ba shinondani darakhtu buttahoi sersoyavu zebo va sarsabz namudani mahalli khud diqqati jiddi medihand.

Mutaassifona, manfiati rastanihoro na hama odamon mefah- mand. Odamone yoft meshavand, ki darakhtu buttahoro meburand, gulu giyohhoro poymol mekunand va boisi nobudshavii rastaniho megardand. Onho faromush mekunand, ki rastanihoro nobud kardan oson, vale onhoro sabzondanu kalon kardan khele dushvor ast. Baroi in solhoi ziyod meboyad ranj kashid.

  1. Rastanihoi sabz dar tabiat chi ahamiyat dorand?
  2. Hayvonot va odamon moddahoi organikii baroi khurokashon zaruriro az kujo megirand?
  3. Kabudizor kardani shahru dehot chi ahamiyat dorad?
