Abstract

Six planting spacings in Taxodium ascendens stands were tested and their yield and economic indexes were investigated , including average diameters at the height of breast , average tree heights, average volume of single tree , stocking volume increment and commercial volume per hectare and total production value , cost , interplanted crop revenue and total profits.The results from tested 14-year-old stands showed that the stand with a spacing of 1.5 m4.0 m had the highest integrated benefits , about 2 024 yuan (RMB )hm-2a-1 (timber +interplanted crops), which was 5.9 %higher than that in the stand with a spacing of 2.0m 3.0 m and also 23.2 %～ 53.1 % higher than that in other tested stands.
