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 ...

AI Technical Summary

Problems solved by technology

In the case of normal application of nitrogen, phosphorus, and potassium, adding one or more medium and trace elements plays an important role in balancing the elements required by crops and preventing physiological diseases caused by deficiencies. Trace elements mostly exist as divalent metal ions. Once they enter the fertilizer and soil, because there are a lot of negative divalent carbonate and negative trivalent phosphate in the fertilizer and soil, they are very easy to react with them to form water-insoluble Most of the carbonates and phosphates will lose their activity, and very little can be absorbed by plants, and the utilization rate is limited to a certain extent, so even if the fertilizer is applied in a balanced manner, it does not mean that it is absorbed by the crops in a balanced manner, which is why it has been applied to the soil. Medium and trace elements, but crops sometimes still appear the cause of deficiency symptoms
