Production method for dual acid chelate inorganic compound fertilizer

Abstract

The invention discloses a production method for a dual acid chelate inorganic compound fertilizer, and the product belongs to the field of compound fertilizer manufacture. Apart from containing abundant nitrogen, phosphorus and potassium, the fertilizer also contains medium and trace elements in a variety of amino acids and humic acid chelates. By long-term use of the product, soil structure can be regulated efficiently, soil can be activated, the equalization, stability and lasting effects of the nitrogen, phosphorus and potassium elements can be coordinated, abilities of plants to resist droughts, cold, adversities, continuous cropping, withering and yellowing, and root rot can be improved, and immune functions can be enhanced. The raw materials used in the production of the product include urea, monoammonium phosphate, potassium hydrogen sulfate molten mass, iron amino acid chelate, boron amino acid chelate, copper amino acid chelate, manganese amino acid chelate, molybdenum amino acid chelate, zinc humic acid chelate, calcium humic acid chelate, magnesium humic acid chelate, a controlled release agent, and gaseous ammonia.

Description

Technical field:

[0001] The invention belongs to the field of compound fertilizer manufacture, and in particular relates to a production method of amino acid and humic acid chelated inorganic compound fertilizer. Background technique:

[0002] Inorganic compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It plays a very important role in balancing fertilization, improving fertilizer utilization rate, and promoting high and stable yield of crops. However, it also has some disadvantages, such as its nutrient types. It does not contain medium and trace elements, and cannot supplement the nutrients needed by crops in a targeted manner, so as to achieve a balanced supply of various nutrients to meet the needs of crops and achieve the purpose of improving fertilizer utilization. Studies have found that in the process of plant growth, in addition to a large amount of nitrogen, phosphorus, and potassium, a certain ...
