在缺硫土壤上以石膏、硫磺、硫酸钾镁（SPM）作为流源进行硫肥水稻试验，并设置与石膏等钙量、与SPM等镁量的石灰、MgCl3处理，结果显示，增施硫、钙、镁，水稻均有显著增产，其中硫的增产效果最好；在3个硫肥品种中，以施石膏增产最大、施硫磺效益最佳。讨论了施硫对水稻生长发育、营养状况及对稻谷品质的影响。
Sulfate and rice experiments were conducted on sulfur-deficient soil with gypsum, sulfur and magnesium sulphate (SPM) as flow sources. Calcium and gypsum, calcium and SPM, lime and MgCl3 treatments were also applied. The results showed that increasing sulfur , Calcium, magnesium and rice all increased significantly, of which the sulfur yield was the best. Among the three sulfur fertilizer varieties, gypsum had the highest yield and the best sulfur benefit. The effects of applying sulfur fertilizer on the growth and development of rice, the nutritional status and the quality of rice were discussed.
