AI Technical Summary
The mismatch in the timing of carbon and nitrogen release in existing organic fertilizers leads to nitrogen loss and competition for carbon and nitrogen nutrients, making it impossible to effectively supply the nutrients needed for crop growth.
By using composite phase change paraffin microcapsules to encapsulate nitrogen sources such as urea and carbon skeleton carriers such as microwave-treated straw powder, combined with microcapsule encapsulation and room temperature granulation processes, a nitrogen source slow release and carbon skeleton synergistic matching are formed. Through microwave pore expansion and temperature-sensing controlled release, carbon and nitrogen nutrients are released simultaneously.
It improves nitrogen fertilizer utilization and carbon skeleton degradation capacity, achieves a balanced supply of carbon and nitrogen nutrients, steadily increases crop yield, and maintains product shape and physicochemical quality.
