The “Farming Special Fertilizer for Sewage Reduction and Its Standardized Production Technology and Demonstration and Extension†project has recently passed the appraisal of the Fujian Provincial Science and Technology Department. The vegetable special fertilizer with addition of nitrification inhibitors and heavy metal deactivators has reached international advanced level.
According to reports, the project has developed a set of special fertilizers for reducing soil pollution, including reducing the nitrate and heavy metal content of vegetables. The integration innovation is obvious. Through the analysis of the standard values ​​of the grey correlation method, it is proposed that the assessment of heavy metal pollution in vegetable fields should improve soil quality. The combination of general standard values, physical and chemical properties of soil types and vegetable types provides a new idea for the correct evaluation and scientific treatment of heavy metal pollution in vegetable fields; through a large number of field trials, a summary of technical regulations for the production of special fertilizers for soil Strong practicality.
