Dynamics of the soil base cations in Chinese fir plantations in acid rain region
摘要
Abstract
The dynamics of soil base cations content in different-age Chinese fir plantations in acid rain region were analyzed to study the dynamic law of soil base cations under the background of acid rain. The results showed as follows. The soil base cations were closely related with seasons, forest ages, soil depth. In different seasons, the content of K+and Na+had significant differences in different seasons as those were higher in summer and autumn than in spring and winter (P<0.05) at the same soil depth in the same forest age, while the content of Ca2+and Mg2+were higher in spring or summer than in autumn and winter. In the same season, the content of K+ and Na+ increased from 1 to 5 a, then decreased from 5 to 15 a and increased again from 15 to 20 a, and the content of Ca2+ and Mg2+showed the different trend that rose from 1 to 10 a, and declined from the 10 to 20 a at the same soil depth. With the increase of the soil depth, the content of soil base cations in different age Chinese fir plantations tended to decrease.关键词
