Description

Technical Field

[0001] This invention belongs to the field of agricultural fertilizer technology. It relates to a carbon-enzyme chelated fertilizer containing trace elements and its production process. Background Technology

[0002] Soil, as the foundation for crop growth, is a crucial pillar for ensuring food security and increasing production and income in my country. However, with intensive farming and the heavy use of chemical fertilizers and pesticides, my country's soil has suffered severe damage, ecological degradation, and a series of problems such as organic matter deficiency, compaction, and acidification have become increasingly prominent. These problems not only affect the normal growth of crops but also lead to frequent crop diseases, reduced yields and quality, causing huge losses to farmers.

[0003] Most crop diseases are caused by an imbalance of micronutrients. Although micronutrients are present in small amounts in the soil, they play a crucial role in crop growth and development. Currently, unbalanced fertilization is one of the main causes of micronutrient imbalance. Many growers focus only on major nutrients such as nitrogen, phosphorus, and potassium when fertilizing, neglecting the supplementation of micronutrients, microorganisms, and organic matter. This leads to increased soil phosphorus content, and micronutrients become fixed and lose their availability. At the same time, changes in soil pH or EC values ​​also affect the activity of micronutrients. Furthermore, with the increase in multiple cropping index, soil supply cannot meet demand, and sensitive elements are scarce, further exacerbating the problem of micronutrient imbalance.

[0004] To address the aforementioned issues and improve soil fertility and crop yields, the agricultural sector urgently needs a fertilizer that can comprehensively replenish micronutrients, balance soil nutrients, and improve the soil environment. Carbon-enzyme chelated fertilizer has emerged to meet this need. Based on modern agricultural balanced fertilization theory, it is produced through advanced processes such as propagation, activation, and chelation of active minerals, micronutrients, organic matter, and microorganisms. It is a high-tech microbial fertilizer rich in multiple nutrients and elements.

[0005] Carbon-enzyme chelated fertilizers have the following significant advantages: First, they can effectively replenish the micronutrients needed by the soil, balance soil pH, and improve the soil environment; second, they can promote the growth of microorganisms, using beneficial microorganisms to control harmful microorganisms and enhance crop resistance to stress; third, they can stimulate plant growth, improve crop quality, and increase crop yield. However, the carbon-enzyme chelated fertilizers on the market are currently diverse, with varying production processes, and their quality and effectiveness are inconsistent. Therefore, developing a carbon-enzyme chelated fertilizer containing micronutrients and its production process to better meet the needs of agricultural production has significant practical importance and application value.

[0006] In summary, existing soil problems and the imbalance of micronutrients caused by unbalanced fertilization urgently need to be addressed. Carbon-enzyme chelated fertilizers, as a novel type of fertilizer, offer significant advantages in supplementing micronutrients, balancing soil nutrients, and improving the soil environment. However, current carbon-enzyme chelated fertilizers on the market still have some shortcomings, requiring further optimization of production processes to improve fertilizer quality and efficacy. Summary of the Invention

[0007] To overcome the shortcomings of existing technologies, this invention provides a carbon-enzyme chelated fertilizer containing trace elements and its production process, which is achieved through the following technical solution:

[0008] A carbon-enzyme chelated fertilizer containing trace elements is made from the following raw materials in parts by weight:

[0009]

[0010] The potassium humate mentioned is obtained by reacting weathered coal or lignite with potassium hydroxide.

[0011] The mineral powder is made from silicon-calcium-magnesium ore, which is activated by calcination at a high temperature of 1000-2000 degrees Celsius, and then processed by Raymond mill to obtain a fineness of 100-120 mesh.

[0012] The zinc sulfate and magnesium sulfate mentioned are prepared by chelation reaction with amino acids.

[0013] The carbon enzyme solution is a microbial metabolite formed after Bacillus bacteria undergo a growth-promoting reaction with organic carbon.

[0014] The furfural residue mentioned above is the waste residue from the production of furfural using corn cobs as raw material, with an organic matter content of ≥90% and a pH of 2-4.

[0015] A production process for a carbon-enzyme chelated fertilizer containing trace elements includes the following steps:

[0016] (1) After screening, the ore is calcined at high temperature and then crushed into 100-120 mesh by Raymond mill, and then acidified with furfural.

[0017] (2) Magnesium sulfate and zinc sulfate amino acids undergo a chelation reaction to form an amino acid chelate of magnesium and zinc.

[0018] (3) Prepare carbonase solution by reacting Bacillus with organic water-soluble carbon to promote growth;

[0019] (4) Carbon-enzyme chelate fertilizer containing trace elements is produced by steam drum spraying granulation.

[0020] Furthermore, in step (1), the ratio of ore to furfural is 3-5:1, preferably 4:1.

[0021] Furthermore, the reaction conditions in step (2) are as follows: magnesium sulfate monohydrate: zinc sulfate monohydrate: 40% composite amino acid liquid in a weight ratio of 2-4:1:5-8, preferably 3:1:6, and the reaction time is 2-5 hours.

[0022] Furthermore, Bacillus species include Bacillus subtilis and Bacillus megaterium.

[0023] Furthermore, the temperature for the growth-promoting reaction is 35-45 degrees Celsius, and the reaction time is 68-80 hours.

[0024] The beneficial effects of this invention compared to the prior art are:

[0025] In this invention, trace elements undergo a chelation reaction, preventing antagonism when applied to soil and thus increasing fertilizer utilization. The addition of carbon enzyme solution imbues the fertilizer with microbial activity, improving soil structure and enhancing fertilizer efficiency. The application of carbon enzyme chelated fertilizer containing trace elements in production prevents nutrient deficiencies in crops, improves soil quality, and increases yield.
