摘　　要：[目的]为资源化利用脱硫废弃物和改良盐碱地提供科学依据。[方法]通过在盐碱地上施用脱硫废弃物并且开展种植甜菜比较试验,研究盐碱地施用脱硫废弃物对土壤化学性质和甜菜生长量、产量的影响。[结果]与未施用脱硫废弃物的盐碱地相比,施用脱硫废弃物后盐碱地土壤的pH、全盐量和碱化度均有不同程度的下降,分别降低3.19%、28.32%、23.05%;在施用脱硫废弃物的盐碱地上种植甜菜后,甜菜的出苗率、苗高、块根长、块根粗和块根鲜重分别提高33.19%、17.84%、8.95%、14.38%、56.84%。[结论]脱硫废弃物可以明显改善土壤的化学性质,更有利于甜菜生长。[ Objective ] To provide scientific basis for resource utilization of desulfurization byproducts and improvement of salina and alkaline soil. [ Method] A comparative experiment was conducted in Qianjin Farm of Pingluo County in Ningxia. The effects of desulfurization byprod- ucts on the chemical properties of soil and growth, yield of sugar beet were studied. [ Result] The results showed that applying desulfurization byproducts decreased soil pH, soil total salt content and ESP by 3.19%, 28.32% and 23.05%, respectively, and significantly increased the emergence rate, plant height, root length, root diameter and fresh weight of sugar beet by 33. 19% , 17.84% , 8.95% , 14.38%, and 56. 84%, respectively. [ Conclusion] The application of desulfurization byproducts could obviously improve chemical property of saline and al- kaline soil and it was beneficial to the grwoth of sugar beet.
