| Abstract: | A Chinese fir (Cunninghamia lanceolata) pure stand and a mixed stand of Chinese fir and Alniphyllum fortunei planted on the poor site in Jianou of Fujian Province were used to analyze the dynamic growth process.The result indicated that the increments of tree heighe,DBH and volume of pure stand and mixed stand were similar in the first 3 years after planting ,and soon the former exceeded the latter greatly. Compared with pure stand the tree volume of mixed stand at age 16 increased by 63 88%.The peak growth was found to appeared earlier with bigger peak value and longer fast growth period in mixed stand.The results suggests that interplanting with Alniphyllum fortunei could accelerate stem growth of Chinese fir and is a effective way of cultivating large diameter wood. |
