| 摘 要： | 利用田间定位试验,研究脱硫废弃物和耐盐牧草对土壤盐分的影响,同时研究脱硫废弃物对几种牧草生产性能的影响,探讨脱硫废弃物和耐盐牧草对碱性盐土的改良效果。结果表明,脱硫废弃物和耐盐牧草对碱性土壤0~20 cm土层的ESP、pH、代换性Na+含量均有降低作用;同时也降低(HCO3-+CO32-)含量、一价阳离子(K++Na+)含量,使土壤物理和化学性质改善,有利于植物的生长,增加产量。

| Abstract: | The improved effects of flue gas desulphurization by-product and grass on alkali soil was explored to offers reference for improving alkali soil and choosing salt tolerance grass varietis.The field location test was used to analyze the effects of flue gas desulphurization by-product on soil salinity and performance trait of several grass varities.The results showed that by-product of flue gas desulphurization and grass made a reduction in exchangable sodium percentage,pH,the content of(K++Na+) and(HCO3-+ CO... |
