Description
ORGANIC COMPOUND FERTILIZER MADE FROM TRADITIONAL CHINESE
MEDICINE RESIDUES THAT CAN IMPROVE BARREN SOIL AND ITS
PROCESSING METHOD
The invention relates to the field of resource utilization of solid waste such as traditional Chinese medicine residues and molybdenum tailings, and fertilizer production technology, specifically to an organic compound fertilizer made from traditional Chinese medicine residues that can improve barren soil and its processing method.
Background Technology
The Loess Plateau is a major grain-producing area in China and a traditional dryland farming region. Due to natural factors such as fragmented terrain, loose soil, and concentrated rainfall, the area suffers from severe soil erosion, barren arable land, and low land productivity. Specifically, the soil is seriously deficient in organic matter, and except for abundant available potassium, nitrogen and phosphorus nutrients are lacking, and trace elements such as effective zinc, boron, manganese, and molybdenum are also deficient. However, the current fertilization in this region is still dominated by nitrogen and phosphorus inorganic fertilizers like urea and diammonium phosphate, resulting in serious soil structure damage, increased risk of soil erosion, further soil degradation, and declining land productivity.
Waste traditional Chinese medicine residues are rich in organic matter, nitrogen, phosphorus, potassium, amino acids, crude fiber, and other nutrients. When applied to farmland, they can increase the soil’s organic matter, alkaline hydrolyzable nitrogen, available phosphorus, and available potassium content, improve soil aggregate structure, and significantly enhance the soil's physical and chemical properties. These residues are light in weight, have good aeration properties, and can improve soil permeability, making them a high-quality organic fertilizer raw material mainly for increasing organic matter content and supplementing nitrogen and phosphorus. Tests have shown that adding a certain proportion of traditional Chinese medicine residues to the soil where corn is planted improves the absorption rate of nutrients by the corn plants, leading to more vigorous growth; it also enhances the root growth environment of the corn, promotes the development of the root system, increases yield, and improves the quality of the corn. Therefore, scientifically utilizing waste traditional
Chinese medicine residues to produce organic fertilizers to address the challenges of waste residue treatment and disposal and to reduce environmental pollution has gained widespread attention.
At present, although there are various production methods for organic fertilizers based on traditional Chinese medicine residues, they have the following problems:
First, the raw material components are numerous, requiring more than 10 kinds of raw materials, and some even up to 17, which leads to low utilization efficiency of traditional Chinese medicine residues and a complicated production process. Second, using only traditional Chinese medicine residues and other organic wastes to produce organic fertilizers results in large amounts of usage, slow effectiveness of macronutrients like nitrogen, phosphorus, and potassium, insufficient content of secondary and trace elements like calcium, magnesium, sulfur, iron, manganese, silicon, zinc, molybdenum, and boron, and low bioavailability. Therefore, existing organic fertilizers cannot effectively target the barren soils of the Loess Plateau, making it difficult to fertilize the soil, improve soil structure, and address soil erosion issues.
The purpose of the present invention is to provide an organic compound fertilizer made from traditional Chinese medicine residues that can improve barren soil and its processing method to solve the problems mentioned in the background technology.
To achieve the above purpose, the present invention provides the following technical solution: An organic compound fertilizer made from traditional Chinese medicine residues that can improve barren soil, comprising the following parts by weight: 60-80 parts of traditional Chinese medicine residues, 6-8 parts of urea, 12-14 parts of superphosphate, 2.5-3.5 parts of potassium chloride, 4-6 parts of harmless molybdenum tailings, and 1.5-2.5 parts of humic acid.
Preferably, it comprises the following parts by weight: 70 parts of traditional
Chinese medicine residues, 7 parts of urea, 13 parts of superphosphate, 3 parts of potassium chloride, 5 parts of harmless molybdenum tailings, and 2 parts of humic acid.
Preferably, it comprises the following parts by weight: 60 parts of traditional
Chinese medicine residues, 8 parts of urea, 12 parts of superphosphate, 3.5 parts of potassium chloride, 4 parts of harmiess molybdenum tailings, and 2.5 parts of humic acid.
Preferably, it comprises the following parts by weight: 80 parts of traditional
Chinese medicine residues, 7 parts of urea, 14 parts of superphosphate, 2.5 parts of potassium chloride, 6 parts of harmless molybdenum tailings, and 1.5 parts of humic acid.
A processing method for the organic compound fertilizer made from traditional
Chinese medicine residues that can improve barren soil, comprising the following steps: (1) Mixing the traditional Chinese medicine residues evenly, drying them in the air or at low temperatures, and grinding them into powder; (2) Taking 60-80 parts of traditional Chinese medicine residues, 6-8 parts of urea, 12-14 parts of superphosphate, 2.5-3.5 parts of potassium chloride, 4-6 parts of harmless molybdenum tailings, and 1.5-2.5 parts of humic acid, and mixing them evenly; (3) Adding water to the above mixed materials to adjust the moisture content to 40%-60%, covering with plastic film, and storing in a sealed condition for 5-7 days; (4) Spreading out to dry or drying until the moisture content is <10%, and processing into granular fertilizer.
Preferably, in step (3), the storage temperature in the sealed condition is controlled to be <60°C.
Preferably, in step {4}, the drying temperature is controlled to be <70°C.
The beneficial effects of the present invention compared to the existing technology are: 1) The present invention targets the characteristics of barren soil on the Loess
Plateau, focusing on increasing organic matter, supplemented by nitrogen and phosphorus and enriched with trace elements, providing comprehensive nutrient content in the fertilizer. The present invention combines traditional Chinese medicine residues, urea, superphosphate, potassium chloride, molybdenum tailings, and humic acid in specific proportions, which addresses the drawbacks of pure traditional Chinese medicine residue organic fertilizers, such as slow effectiveness of macronutrients and insufficient content of secondary and trace elements, while aligning with China's fertilizer reduction policy. This can significantly promote the combined use of organic and inorganic fertilizers, increase soil organic matter content, reduce the risk of nitrogen and phosphorus non-point source pollution due to soil erosion in the Loess
Plateau region, and achieve environmental friendliness. 2} The raw material composition of the present invention is relatively simple, requiring only six raw materials, which effectively meets the improvement needs of barren soil on the Loess Plateau. 3) The present invention reduces the usage of traditional Chinese medicine residues, avoiding the drawbacks of large amounts of pure traditional Chinese medicine residue fertilizer application. 4) The present invention fully considers the timeliness of the fertility of traditional
Chinese medicine residue organic fertilizer by adding small amounts of highly effective inorganic nitrogen, phosphorus, and potassium elements to enhance the fertility efficiency of traditional Chinese medicine residue organic fertilizer, promoting the combined use of inorganic and organic fertilizers. 5) The present invention, by adding harmless molybdenum tailings as a source of secondary and trace elements, reduces the use of inorganic secondary and trace element substances, advancing the national process of inorganic fertilizer reduction, and also contributes to the clean production and comprehensive utilization of waste from molybdenum mining enterprises. It provides a resourceful solution for the treatment of large amounts of molybdenum tailings, addressing the significant waste of land resources, serious environmental issues, and safety hazards caused by tailings accumulation. 6) The present invention does not use fermentation agents and does not require fermentation of traditional Chinese medicine residues during the preparation process, 5 ensuring production safety. The entire production process is simple to operate, with low technical requirements for operators, significantly reducing labor costs. 7) The present invention, through the chelation of humic acid with traditional
Chinese medicine residues, increases the content of free humic acid in the fertilizer and the bioavailability of nutrients, enhancing the disease resistance and stress tolerance of crops. 8) The present invention, based on traditional Chinese medicine residues, combines urea, superphosphate, potassium chloride, molybdenum tailings, and humic acid, completing the formulation of the organic compound fertilizer in one step. The implementation steps are simple, the process flow is straightforward, the industrial operation process is simple, conducive to intensive production, and meets the needs of industrialization, making it highly promotable. 9) High degree of harmlessness and sanitation: By chelating humic acid {HA) with traditional Chinese medicine residues, the present invention significantly increases the content of free-state humic acid and the bioavailability of secondary and trace elements, improving the ability to chelate heavy metal ions such as Pb, Cr, and Cd, and reducing the ecological risk of heavy metals brought by fermented traditional Chinese medicine residues and molybdenum tailings. 10) The introduction of organic matter from traditional Chinese medicine residues increases the soil's particle aggregation capacity, promoting the formation of stable soil aggregates, effectively improving the stability of the loess structure, and mitigating soil erosion.

Tests have determined that the organic compound fertilizers made from fermented traditional Chinese medicine residues according to Examples 1-3 meet the quality standards for bio-organic fertilizers (NY 884-2012): total nutrient content (N +
P2Os + K20) (on a dry basis) 211%; organic matter 242%; moisture content £10%.
Among the above examples, Example 1 is the best embodiment.
The crop yield and soil fertility effects of the organic compound fertilizer in
Example 1 are illustrated as follows:
The organic compound fertilizer made from traditional Chinese medicine residues in the present invention, when used for grain crops {such as corn), is recommended for use as a one-time basal fertilizer applied uniformly across the entire soil layer (with little or no follow-up fertilization), with an application rate of 250-350Kg per mu.
Test crop: Corn, variety Yudan 958.
Test location: Yan'an Ecological Experimental Station, Institute of Earth
Environment, Chinese Academy of Sciences.
Test period: June to October 2016; May to October 2017.
The comparison fertilizers used were hydrolyzed oil residue organic fertilizer
(Control 1, produced by Shandong Guangda Fertilizer Technology Co., Ltd.) and nitrogen-phosphorus-potassium inorganic fertilizer (Control 2). The application rates of the hydrolyzed oil residue organic fertilizer and the fermented traditional Chinese medicine residue organic compound fertilizer in the present invention were the same, at 250Kg per mu; the nitrogen-phosphorus-potassium inorganic fertilizer was applied according to the recommended fertilization rate for high-yield corn. All fertilizers were applied uniformly across the entire soil layer as a one-time basal fertilizer, with no follow-up fertilization. Table 1 shows the crop yield increase effect of the organic compound fertilizer made from traditional Chinese medicine residues in the present invention {the 2016 growing season was shorter, so the yield is expressed as the total dry weight of above-ground biomass at harvest); Table 2 shows the improvement in the main soil fertility indicators after two years (i.e, 2017) of applying the organic compound fertilizer made from traditional Chinese medicine residues in the present invention.
