Abstract

The invention discloses a complete complex fertilizer and a production method thereof. The complete complex fertilizer comprises, in percent by mass, 30-60 parts of potassium dihydrogen phosphate, 30-60 parts of potassium nitrate, 1-5 parts of EDDHA iron,1-5 parts of EDTA zinc-manganese-molybdenum, 1-5 parts of copper amino acid,1-5 parts of liquid complex organic boron, and 1-5 parts of a polyvinyl alcohol solution with the concentration of 1%. The production method for the complete complex fertilizer comprises the following steps: mixing potassium dihydrogen phosphate and potassium nitrate successively with EDDH iron, EDTA zinc-manganese-molybdenum and copper amino acid in a granulator, uniformly mixing, then gradually spraying a mixture of liquid organic boron and polyvinyl alcohol, and performing granulation molding and drying, so as to obtain the complete complex fertilizer. The fertilizer contains macroelements and also contains medium and trace elements subjected to complexing, is high in nutrient utilization rate, diverse in usage manner, wide in usage scope and flexible for trace-element supplement, the ratio of trace elements can be flexibly adjusted according to the soil element lacking status and demands of different crops on trace elements, and the fertilizer is well applicable to soil testing and fertilizer recommendation.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a full-valent complex fertilizer and a production method thereof. Background technique [0002] The importance of fertilizers to agricultural production is unquestionable. In addition to the three major elements of nitrogen, phosphorus, and potassium, the nutritional elements required for plant growth and development also require a variety of secondary elements such as calcium, magnesium, and sulfur, and trace elements such as iron, Zinc, manganese, copper, boron, molybdenum, etc. These elements are important components of enzymes, coenzymes, vitamins, hormones, etc. in plants, and directly participate in the metabolic process of organisms. Plants can only obtain high-quality and high-yield harvests if they obtain a balanced supply of these necessary macro, medium and trace elements. However, due to the antagonism between these trace elements and the ...
