近年来,随着工业的发展,化肥生产逐渐转向不含硫的浓缩肥料,硫酸铵、过磷酸钙、硫酸钾等含硫肥料的数量在大大减少;用电力和原子能代替富含硫的燃料,大气中可供作物吸收利用的硫化物气体也在减少。但是,随着氮肥用量的增加,土壤有机硫的矿化和作物对硫 In recent years, with the development of industry, the production of fertilizers has gradually shifted to concentrate fertilizers that do not contain sulfur. The quantity of sulfur-containing fertilizers such as ammonium sulfate, superphosphate and potassium sulfate has been greatly reduced. The replacement of sulfur-rich fuels with electricity and atomic energy, The amount of sulfide gas available to the crop in the atmosphere is also decreasing. However, as the amount of nitrogen fertilizer increased, soil organic sulfur mineralization and crop sulfur
