Abstract: Taking Newcotton 33B, Zhongmiansuo 12, Za29 and Za29 F1 as test materials, the reductive activities of cotton lateral root in soil layers of 0－5 cm, 5－10 cm, 10－15 cm, 15－20 cm and below 20 cm at different developmental stages were determined in 1999 and 2001. The results showed that the root sy
