１９８８年以来，全省２９个硫肥试验中，有２１个施硫增产。早稻、晚稻、油菜、蚕桑和甘薯施硫平均分别增产１３．８％，９．０％，１６．５％，１７．６％和１１．２％。施硫能提高油菜的油酸、亚油酸和亚麻酸含量，提高桑叶的氨基酸和脂肪含量，并有促进作物早熟和增强抗性的作用。硫对作物的增产效果受成土母质、土壤质地及土壤水分状况的影响。在酸性土壤上，不同品种的硫肥对油菜的增产效果为：石膏＞过磷酸钙＞硫磺＞硫铵 Since 1988, 21 sulfur fertilizers have been applied to 29 sulfur fertilizers in the province. The yields of early rice, late rice, rapeseed, sericulture and sweet potato were increased by 13.8%, 9.0%, 16.5%, 17.6% and 11.2% respectively. Application of sulfur can increase oleic acid, linoleic acid and linolenic acid content of rapeseed, increase the content of amino acids and fat in mulberry leaves, promote the precociousness of crops and enhance the resistance. The effect of sulfur on crop yield is affected by soil parent material, soil texture and soil moisture status. In acid soils, the effects of different varieties of sulfur fertilizer on rapeseed production were as follows: gypsum> superphosphate> sulfur> ammonium sulfate
