| ABSTRACT |
| An investigation and on 13-year-old (1984~1996) Chinese fir and Tsoong stree mixed forests in Jianou City, Fujian Province, China was carried out to compare the influences of different interplanting types of individual tree-tree, row-row, row-strip (three rows) and pure Chinese fir stands on soil properties. Compared with the pure stands of Chinese fir, the mixed stands exerted a positive effect on soil fertility, with increases in soil organic matter, total N, available P and available K. Moreover, improvements were also observed in soil enzymatic activities, aggregate structure, structure stability, status of soil porosity, soil aeration and penetrability in mixed stands. The row-row interplanted stands had the best effect on tree growth and soil properties among these mixed forests. In the southern subtropical region, the spreading of the row-row mixing model of the two tree species would be helpful to preventing the soil from fertility deterioration caused by successive plantat ion of Chinese fir. |
