硫是作物生长发育不可缺少的营养元素,是蛋白质的组成成分,其需要量仅次于氮磷钾,有研究发现,增施硫肥有利于增加马铃薯还原糖含量、促进马铃薯氮素积累和组成蛋白质的含硫氨基酸合成,增加马铃薯粗蛋白含量等。随着作物产量不断提高,作物从土壤中带走的硫越来越多,但含硫化肥的施用 Sulfur is an indispensable crop growth and development of nutrients, is the composition of protein, its requirement is second only to NPK, it has been found that increased sulfur fertilizer is conducive to increasing the content of reducing sugar in potato and promoting potato nitrogen accumulation and composition Protein sulfur amino acid synthesis, increase potato crude protein content. As crop yields continue to rise, more and more sulfur is taken away from the soil by crops, but application of sulfur-containing fertilizers
