本文叙述了硫素营养状况对蔬菜品质的显著作用。硫素供给不足,蔬菜将出现明显的缺硫症状。施用硫肥是降低植物对有毒元素砷或锑等吸收的有效措施,也是预防植物过量吸收重金属镉或锌等的有效手段。施硫可增加蔬菜必需氨基酸含量,特别是含硫的蛋氨酸等,从而提高了其营养价值。施硫还可提高蔬菜对病虫害的抵抗能力。 This article describes the significant role of sulfur nutrition in the quality of vegetables. Inadequate supply of sulfur, vegetables will appear obvious symptoms of sulfur deficiency. Sulfur fertilizer is an effective measure to reduce plant absorption of toxic elements such as arsenic or antimony, as well as an effective measure to prevent plants from excessive absorption of heavy metals such as cadmium or zinc. Application of sulfur can increase the essential amino acid content of vegetables, especially sulfur-containing methionine, thereby increasing its nutritional value. Application of sulfur can also increase the resistance of vegetables to pests and diseases.
