Problems solved by technology

At present, the utilization rate of chemical fertilizers is less than 30%, and the rest is lost with water and soil. The application of chemical fertilizers not only causes great waste, but also pollutes soil and groundwater resources. Therefore, the development of slow-release fertilizers is listed as a key development support project by the state.

Abstract

The invention discloses a picria felterrae controlled-release fertilizer and a preparation method thereof and belongs to the technical field of fertilizer preparation. The picria felterrae controlled-release fertilizer is prepared from the following raw materials in parts by weight: 200-800 parts of fertilizer particles and 25-120 parts of coating materials. The picria felterrae controlled-release fertilizer is prepared through the steps of fermentation, concentration, granulation, drying, cooling and coating. The picria felterrae controlled-release fertilizer is moderate and stable in controlled release rate; the fertilizer particles are balanced in nutrient; the loss rate of the fertilizer can be effectively reduced; the utilization efficiency of the fertilizer is improved; fast health growth of picria felterrae is promoted; and the yield of the picria felterrae is improved.
