Abstract

The importance of agroforestry systems in CO2 mitigation has become recognized worldwide in recent years However little is known about carbon C sequestered in poplar intercropping systems The main objective of this study is to compare the effects of three poplar intercropping designs configuration A 250 trees ha−1 configuration B 167 trees ha−1 and configuration C 94 trees ha−1 and two intercropping systems wheat–corn cropping system and wheat–soybean cropping system on biomass production and C stocks in poplar intercropping systems The experiment was conducted at Suqian Ecological Demonstration Garden of fastgrowing poplar plantations in northwestern Jiangsu A significant difference in C concentration was observed among the poplar biomass components investigated P ≤ 005 with the highest value in stemwood and the lowest in fine roots ranging from 4599 to 5267 g kg−1 There was also a significant difference in C concentration among the different crop components P ≤ 005 and the highest concentration was observed in the corn ear Over the 5year period the total poplar biomass increased with increasing tree density ranging from 877 to 1512 t ha−1 while annual biomass production among the crops ranged from 469 to 1658 t ha−1 in the three configurations Overall total C stock in the poplar intercropping system was affected by configurations and cropping systems and configuration A obtained the largest total C stock reaching 167 t C ha−1 for the wheat–soybean cropping system and 189 t C ha−1 for the wheat–corn cropping system Results from this case study suggest that configuration A was a relative optimum poplar intercropping system both for economic benefits and for C sequestrationThis study was fully supported by National Key Project of Scientific and Technical Supporting Programs funded by Ministry of Science Technology of China during the 11th 5year Plan no 2006BAD03A1505The authors would like to thank Profs Huanchao Zhang and Luozhong Tang from Nanjing Forestry University for their suggestions and kind assistance We are indebted to the two anonymous reviewers for their helpful comments and English corrections on the manuscript
