| Abstract: | Six
planting spacings in Taxodium ascendens stands were tested and their yield and
ceonomic 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 profitsThe results from tested 14yearold stands showed that the stand with a
spacing of 15m40m had the highest integrated benefits,about 2
024yuan(RMB)hm-2a-1(timber interplanted crops),which was 59% higher than that in the
stand with a spacing of 20 m30 m and also 232S1% higher than that in other tested
stands |
