Abstract:

Jerusalem artichoke is adaptive greatly to various environments. In the salinized coastal area, Jerusalem artichoke plantation will be benefit for soil quality improvement and carbon sequestration. In order to improve the yield and carbon sequestration, the effect of ridge cultivation on the growth and nutrient uptake of Jerusalem artichoke was investigated in a coastal area. The objective was to provide some evidences for better management of Jerusalem artichoke in the salinized coastal area. Results showed that the ridge cultivation increased significantly the yield, biomass and nutrient uptake of Jerusalem artichoke. The increase rates of yield, biomass and carbon sequestration were 15%, 47% and 29%, respectively. Overall, the ridge cultivation is benefit for yield improvement and carbon sequestration of Jerusalem artichoke in the salinized coastal areas.
