Poplars are fast-growing species that were planted pure in the past. Mixed plantations of poplar with nitrogen fixing species have been recommended recently to increase the soil fertility. In this study, Ameraican poplar (Populus deltoids) has been planted with Peanut (Arachic hypogaea). The research was carried out on the base of randomized complete block design with five treatments and three ...
The main objective of this study was to compare the effects two densities (278 stems·ha ?1 with spacings 6 m × or 4.5 8 m, 400 5 3 m) and three poplar clones (NL95, NL895, NL797) on productivity carbon (C) sequestration ecosystems. results showed that planting density significantly affected biomass a single tree. mean tree clone NL95 higher in all than other clones, significant difference for s...
TThe forest plantation strategy is to do with the identification of the most appropriate zones and the areas that are most suitable for different species. However, the success of this strategy requires the precise determination of the species ecological demands and the evaluation of the land before the establishment of the plantation. The purpose of this study is to assess the ecological capabi...
Tree species composition was important for carbon storage within the same climate range. To quantify the dynamics of ecosystem carbon allocation as affected by different tree species, we measured the above- and below-ground biomass accumulation in 22 years, as well as the tissue carbon concentrations of trees in Cunninghamia lanceolata plantation and Michelia macclurei plantation. Results indic...
