滴灌条件下不同盐生植物对盐渍化土壤的脱盐效果研究
Effects of Different Halophyte Plants on Soil Desalination under Drip Irrigation Conditions
摘要
Abstract
[Objective] A field experiment was conducted to evaluate the effect of planting halophyte on desalination in salinization soil under drip irrigation conditions. [ Method ] Two kinds of halophyte plants Suaeda salsa and Salicomia bigelovii were used in this study. [ Result ] The result showed that soil salinity were influenced significantly by both Suaeda salsa and Salicornia bigelovii under the drip irrigation conditions, especially for soil salinity of 0 -20 cm layer. The total salt content, Na + , Cl - , and K + concentration in soil were reduced significantly by planting halophyte plants, but the soil pH was not affected. Suaeda salsa had the better desalination effects than Salicornia bigelovii. Salt ions Na+ and K+ concentrations were decreased with planting Suaeda salsa and Cl- concentration was reduced significantly with planting Salicornia bigelovii. [ Conclusion ] The pattern of drip irrigation combined with biological desalination mode could ameliorate soil salinization and Suaeda salsa can be used as the suitable desalination plant. Those results make sense for utilization of saline soil.关键词
