The Study of Improving Saline-Alkali Soils by Means of the Application of Desulfurization Gypsums in Baicheng

Abstract:

The pot experiments were carried out to test planting of oil sunflower with the application of desulfurization gypsum in ameliorating sodic salinity soils. Results showed that exchangeable sodium pH values decreased significantly while soil salt content increased. The germination rate and yield of the sunflower increased significantly after desulfurization gypsum was applied, but excessive application of desulfurization gypsum inhibited germination and growth of the plant. There is the best improvement after application of 33.75(t·hm^-2) of desulfurization gypsum in the 0-20 cm surface layer of soils moderate in sodic salinity, such conditions are favorable for sunflower growth.
