Description

technical field

[0001] The invention relates to a soft-sensing modeling method for the nutrient content of compound fertilizers based on mixed multi-models. Background technique

[0002] Compound (mixed) fertilizer is an inevitable trend in the development of modern chemical fertilizer industry. In countries with developed chemical fertilizer industry, its output has accounted for 70% to 80% of the total fertilizer consumption. In my country's "Tenth Five-Year Plan", the production of compound (mixed) fertilizers has been taken as the direction of chemical fertilizer industry structure adjustment. In recent years, the production of compound (mixed) fertilizers in my country has developed rapidly, and thousands of sets of compound (mixed) fertilizer production devices with aggregate method have been built successively. Sulfur-based nitrogen, phosphorus and potassium (S-NPK) compound fertilizer is popular among farmers for its advantages of being suitable for various food cro...
