Abstract
Maqolada Farg'ona viloyati iqlim-sharoitida shakllangan o'tloqi-voha tuproqlari va Indigofera tinctoria L. o'simligi tarkibidagi ayrim noyob elementlar miqdori tavsiflangan. Noyob elementlar miqdorlari litosfera klarkiga taqqoslangan. O‘rganilgan o‘tloqi-voha tuproqlari tarkibida U, Yb va Th elementlari miqdor jihatdan ko‘p to‘plangan, ya’ni akkumulyatsiyalangan. O'tloqi-voha tuproq sharoitida yetishtirilgan Indigofera tinctoria L. o'simligi tarkibidagi Sm, U, Yb, Th noyob elementlar biologik singdirish koeffitsiyenti miqdorlari aniqlangan. O‘tloqi-voha tuproqlarida yetishtirilgan Indigofera tinctoria L. o‘simligi bargida Sm, U, Yb va Th ning miqdori uning ildiz, poya, urug‘lariga nisbatan ko‘p. Lekin biologik singdirish koeffitsiyenti (BSK) qiymatiga ko‘ra, ushbu elementlar Indigofera tinctoria L. o‘simligi organlarida to‘planmagan, ya’ni (Kb<1). Jumladan, o‘simlik ushbu elementlar bilan zararlanmagan.References
