Definitions

  • the invention relates to the field of fertilizer manufacturing, specifically the field of sulfur fertilizer production, that is, a round particle quick-acting high-concentration sulfur fertilizer and a production method.
  • Sulfur is an indispensable and important element in the process of crop growth. In addition to a large amount of nitrogen, phosphorus and potassium, the amount of sulfur required by crops is similar to that of phosphorus. In some sulfur-loving crops, the demand for sulfur is even much greater than phosphorus. It is called the fourth nutrient element after NPK. To synthesize protein in crops, sulfur must be used. The ratio of sulfur and nitrogen in grain protein is 1:15. If sulfur is insufficient, nitrogen will not be absorbed by crops. Sulfur also promotes the formation of oil in the body and increases the plant's ability to resist cold, drought, and pests. The application of sulfur fertilizer can increase the utilization rate of a large number of elements, which can reduce the amount of fertilizer and save fertilizer and increase efficiency.
