红砂土施用不同硫肥品种和用量的田间试验结果表明：（１）红砂土施用硫肥能增加芝麻和油菜的籽粒产量，每ｈｍ２施４０ｋｇＳ的普钙处理增产达５％显著水平，产量分别比对照提高７．６％和１１．３％；（２）３种硫源对芝麻和油菜籽粒的增产效应顺序如下：普钙４０＞石膏４０＞硫磺４０；（３）每ｈｍ２施２０和４０ｋｇＳ的石膏处理对籽粒产量无显著性差异；（４）施用硫肥能提高红砂土耕层土壤有效硫含量，普钙处理的土壤在芝麻收获后其有效硫含量增加达５％显著水平；（５）红砂土施用硫肥显著提高了芝麻籽粒的Ｎ，Ｓ含量。
The results of field experiments on the application of different sulfur fertilizers and dosages in red sandy soil showed that: (1) The application of sulfur fertilizer on red sandy soil increased the grain yield of sesame and rapeseed. The yield of calcium increased 40% Increased by 7.6% and 11.3% respectively compared with the control; (2) The sequence of increasing yield of sesame and rapeseed by the three sulfur sources was as follows: general calcium 40> gypsum 40> sulfur 40; (3) 40kgS gypsum treatment had no significant difference on grain yield; (4) Application of sulfur fertilizer could increase soil available sulfur content in red sand soil, and the available sulfur content increased by 5% (5) Application of sulfur fertilizer on red sandy soil significantly increased N, S content of sesame seeds.
