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. By combining standard values, physicochemical properties of soil types, and vegetable types, a new idea for correct evaluation and scientific treatment of heavy metal pollution in vegetable fields was proposed; through a large number of field trials, technical regulations for the production of special fertilizers for reducing pollution were concluded. Strong practicality.
