Description

Technical Field

[0001] The invention relates to the technical field of konjac planting, and in particular to a special fertilizer capable of promoting konjac swelling, and a preparation device and a preparation method thereof. Background Art

[0002] Konjac contains very high levels of glucomannan, a water-soluble dietary fiber. The presence of this ingredient gives white konjac good colloidal properties after processing, but also affects its growth and expansion requirements. Glucomannan is a linear polysaccharide formed by D-glucose and D-mannose connected by β-(1→4) glycosidic bonds. The high water absorption and water retention capacity of glucomannan can form a stable hydration layer in the soil, help form stable aggregates in the soil, help maintain soil moisture, reduce water evaporation, and provide a continuous water supply for konjac, especially under drought conditions; however, if the concentration of glucomannan in the soil is too high, it may cause the soil to be too sticky, affecting the extension of the root system and oxygen exchange, thereby indirectly affecting the growth and expansion of konjac.

[0003] In rainforest climates, frequent rainfall can cause soils to become overly waterlogged. Although the glucomannan in white konjac is highly absorbent and can retain soil moisture in drought conditions, this property can become a problem in situations of excessive moisture. Summary of the invention

[0004] The invention overcomes the shortcomings of the prior art and provides a special fertilizer capable of promoting the expansion of konjac and a preparation device and a preparation method thereof.

[0038] (1) The present invention provides a special fertilizer for promoting the enlargement of konjac, and a preparation device and a preparation method thereof, wherein the formula is 23%-30% of potassium sulfate type compound fertilizer, 22%-28% of biological organic fertilizer, 1%-5% of enlargement agent, 10%-15% of additive, and the rest is water.

The technical problem that konjac contains very high glucomannan and is not conducive to swelling in a wet soil environment is solved.

[0039] (2) The present invention provides a special fertilizer formula that can promote the expansion of konjac, which is 23%-30% of potassium sulfate type compound fertilizer, 22%-28% of biological organic fertilizer, 1%-5% of swelling agent, 10%-15% of additives, and the rest is water. Among them, the additives contain diatomaceous earth, zeolite powder and charcoal powder. By introducing diatomaceous earth, zeolite powder and charcoal powder, the formula can effectively improve the air permeability and drainage of the soil, reduce water accumulation, and prevent the soil from being too sticky. By adding these ingredients, it is possible to effectively reduce the accumulation of water in the soil and prevent the soil from being too sticky, thereby avoiding the problems of difficulty in root breathing and growth stunting.

[0040] (3) The present invention provides a special fertilizer formula for promoting the enlargement of konjac, which is 23%-30% of potassium sulfate compound fertilizer, 22%-28% of biological organic fertilizer, 1%-5% of enlargement agent, 10%-15% of additives, and the rest is water. The enlargement agent contains N-(2-hydroxyethyl) caprolactam and L-arginine. The synergistic effect of N-(2-hydroxyethyl) caprolactam and L-arginine realizes the coupling of cell wall relaxation and nitrogen metabolism: HEC softens the cell wall, L-arginine provides a nitrogen source, and the two together promote the rapid expansion of cells and the enlargement of tubers. Nitric oxide (NO)-mediated signal transduction: L-arginine generates NO, activates the signal pathway of cell division and expansion, and HEC regulates the osmotic pressure inside and outside the cell, supporting the NO-mediated cell expansion process. Synergy of nutrient absorption and transportation: HEC improves nutrient absorption, L-arginine optimizes nitrogen metabolism, and the two together improve the absorption and utilization efficiency of nutrients by konjac. Through this synergistic effect, HEC and L-arginine can effectively promote the rapid expansion of konjac tubers and improve yield and quality.

[0041] (4) Potassium sulfate type compound fertilizer provides quick and effective mineral nutrients among the present invention, while biological organic fertilizer provides long-term stable organic nutrients. The two are used in combination to achieve rapid supplementation and continuous supply of nutrition, and meet the needs of different growth stages of white konjac. The mineral components in the compound fertilizer can rapidly improve the physical and chemical properties of the soil, while the biological organic fertilizer further optimizes soil structure and ecological balance by increasing organic matter and beneficial microorganisms. This dual role can effectively cope with high humidity and rainy problems under the rainforest climate, ensuring that the soil always maintains suitable air permeability and moisture management. The high potassium content in the potassium sulfate type compound fertilizer and the beneficial microorganisms in the biological organic fertilizer work together, which can significantly enhance the stress resistance of white konjac, and help the plant to better cope with adverse conditions in the rainforest climate, such as frequent rainfall, high humidity and potential disease threats.

[0042] (5) The present invention improves soil aeration and drainage, and the combination of potassium sulfate type compound fertilizer and biological organic fertilizer can effectively prevent root hypoxia, ensure the healthy growth of root system, and thus support the normal expansion of tuber. Beneficial microorganisms in biological organic fertilizer can inhibit the occurrence of soil-borne diseases, reduce the risk of diseases caused by high humidity, and protect the healthy growth of white konjac. The organic matter in biological organic fertilizer can regulate the moisture content of soil, both prevent the accumulation of water caused by excessive moisture, and keep appropriate moisture in drought period, ensuring that white konjac can obtain stable water supply under different weather conditions. Potassium sulfate type compound fertilizer with high potassium content can directly promote the expansion of tuber, while organic matter and beneficial microorganisms in biological organic fertilizer provide a good soil environment for the healthy development of tuber. The two are used in combination, which can significantly improve the yield and quality of white konjac.

[0043] (6) The present invention also provides a special fertilizer and a preparation device thereof that can promote the enlargement of konjac, comprising a first curved plate, a second curved plate, a third curved plate, a filter bucket, and a stirring shaft that respectively drives the first curved plate, the second curved plate, and the third curved plate to rotate. Under the joint action of the first curved plate and the second curved plate, a circulating water flow is formed in the fusion box, which flows upward from the inner peripheral side of the fusion box and flows downward in the middle part, so that the upper and lower liquids inside the fusion box are fully mixed, thereby improving the stirring efficiency of fertilizer production. The material bonded together at the bottom of the fusion box is carried to the filter bucket by the water flow and crushed by the third curved plate, thereby further improving the stirring efficiency of fertilizer production.

[0100] As shown in the above table, in embodiment 1-6, as the ratio of N-(2-hydroxyethyl) caprolactam increases from 0.03 to 0.08, the bulb diameter growth rate and bulb mass growth rate increase first and then decrease, which is due to: as N-(2-hydroxyethyl) caprolactam softens the cell wall, the plasticity of the cell is increased, making the cell easier to expand and elongate. Meanwhile, the nitrogen source provided by L-arginine promotes protein synthesis and enhances the construction and repair ability of the cell wall. The coupling effect of this cell wall relaxation and nitrogen metabolism enables the konjac tuber to expand rapidly in a short time, while maintaining the strength and stability of the cell wall. N-(2-hydroxyethyl) caprolactam softens the cell wall, and its amphipathic structure helps to improve the absorption of nutrients by plant roots, especially to the absorption of nitrogen. L-arginine provides a nitrogen source, and also enhances the absorption and utilization efficiency of konjac to other nutrients (such as phosphorus, potassium, etc.) by participating in nitrogen metabolism. Both promote the rapid expansion of cells and the expansion of tubers together. L-arginine generates nitric oxide, activating the signaling pathways for cell division and expansion, while N-(2-hydroxyethyl) caprolactam regulates the osmotic pressure inside and outside the cells, supporting the nitric oxide-mediated cell expansion process. N-(2-hydroxyethyl) caprolactam improves nutrient absorption, and L-arginine optimizes nitrogen metabolism. Together, they improve konjac's absorption and utilization efficiency of nutrients.

[0101] The excessive presence of N-(2-hydroxyethyl) caprolactam may cause excessive softening of the cell wall, resulting in a decrease in the mechanical strength of the cell wall. Although this can promote rapid cell expansion, it may also make the cell wall too fragile to maintain a stable shape. Therefore, although the cell volume increases, the support force of the cell wall is insufficient, resulting in a lack of obvious or reduced growth in the diameter of the bulb. N-(2-hydroxyethyl) caprolactam supports cell expansion by regulating the osmotic pressure inside and outside the cell. However, excessive N-(2-hydroxyethyl) caprolactam may interfere with the normal osmotic pressure balance, resulting in excessive water entering the cell or water loss in the cell, affecting the normal physiological function of the cell. This osmotic pressure imbalance may inhibit the orderly expansion of the cell, thereby affecting the growth of the bulb diameter.

[0102] As can be seen from the above table, in Examples 7-11, as the ratio of diatomite and zeolite powder increases from 1.3, 1.5 to 1.8, 2, the growth rate of bulb diameter and bulb mass first increases and then decreases, which is because: the chemical composition of diatomite is mainly amorphous SiO2, which exists in the form of SiO2·nH2O. Diatomite contains a large amount of amorphous silicon dioxide, which gives diatomite porosity, with a porosity of 60% to 80%, a pore size distribution from a few nanometers to hundreds of nanometers, and an average pore size of nitrogen adsorption of about 10nm. This porous structure gives diatomite good adsorption properties, helps to improve the air permeability and drainage of the soil, reduce water accumulation, and prevent the soil from being too sticky. Zeolite is a hydrous alkali metal or alkaline earth metal aluminum silicate mineral composed of silicon oxygen tetrahedron and aluminum oxygen tetrahedron. Zeolite has a unique internal structure and crystal chemical properties, its skeleton structure is relatively sparse, the specific gravity is low, and the cavity after dehydration can be as large as 47%. The pores and hollow structures of zeolite give it ion exchange properties, which can adsorb and release nutrients and improve the utilization rate of nutrients in the soil. When the ratio of diatomite and zeolite powder is moderate, their porous structure and ion exchange properties can effectively improve the soil environment, promote the healthy growth of konjac roots and the absorption of nutrients, thereby increasing the diameter growth rate and mass growth rate of the bulb, contributing to the healthy growth of the root system and oxygen exchange, thereby promoting the expansion of konjac. This improvement effect is enhanced as the ratio of diatomite and zeolite powder increases, improving the adsorption and retention of nutrients in the soil, allowing konjac to absorb nutrients more effectively, promoting growth, helping to regulate the osmotic pressure of plant cells, supporting cell expansion, maintaining the strength and stability of the cell wall, supporting cell expansion, and affecting the availability of other nutrients in the soil.

[0103] However, when the ratio of diatomaceous earth to zeolite powder is too high, it will have a negative impact on the soil structure and nutrient balance, affect the balance of other nutrients in the soil, lead to growth retardation, interfere with the normal osmotic pressure balance, excessive water entering the cells or water loss in the cells, affect the normal physiological function of the cells, make the cell wall too fragile to maintain a stable shape, and the bulb diameter growth is not obvious or decreases. Too much diatomaceous earth causes the soil structure to be too loose, reducing the soil's ability to retain nutrients. The high ratio of zeolite will excessively absorb nutrients in the soil, affect the normal absorption of nutrients by konjac, and lead to stunted bulb growth.

[0104] Combined with the above experimental results, it can be seen that the bulking agent includes N-(2-hydroxyethyl) caprolactam and L-arginine, wherein the mass ratio of N-(2-hydroxyethyl) caprolactam to L-arginine is 0.06:1. The additives include potassium humate, polyglutamic acid, boric acid, sodium molybdate, diatomaceous earth, alkyl glucoside, zeolite powder, and charcoal powder, wherein the mass ratio of potassium humate: polyglutamic acid: boric acid: sodium molybdate: diatomaceous earth: alkyl glucoside: zeolite powder: charcoal powder is 0.5: 0.3: 0.5: 3.8: 1.6: 0.7: 1.8: 1, which is most conducive to the growth of konjac.

[0105] When the preparation device of the present invention is used, the formula raw materials are sequentially introduced into the fusion box 1 from the feed port 11 according to the experimental steps, and the controller controls the electric heating wire to heat the raw materials in the fusion box 1 in different steps. When stirring the raw materials, the motor 2 is started, and the motor 2 drives the stirring shaft 3 to rotate, and the stirring shaft 3 drives the first arc plate 4, the second arc plate 5, and the third arc plate 8 to rotate respectively. Under the joint action of the first arc plate 4 and the second arc plate 5, a circulating water flow is formed in the fusion box 1, which flows upward from the inner peripheral side of the fusion box 1 and flows downward in the middle, so that the upper and lower liquids inside the fusion box 1 are fully mixed, thereby improving the fertilizer stirring efficiency. The adhesive or unmelted material at the bottom of the fusion box 1 is scraped off by the first arc plate 4 and carried into the filter bucket 7 by the water flow. During the movement, the third arc plate 8 cooperates with the filter bucket 7 to crush it, further improving the fertilizer stirring efficiency. The rotating elastic rod 10 continuously rubs against the gear ring 9, and the filter bucket 7 vibrates to prevent the filter bucket 7 from being blocked. In step 4, the water valve 12 is opened, and the water pump is started to transport the mixed raw materials to the steam sterilization equipment, and then the water valve is closed, and the steam pressure is set to 205.8 kPa and the temperature is set to 130-135° C. The sterilization time is continued for 20-30 minutes, and the mixture is naturally cooled to room temperature to obtain a liquid fertilizer, i.e., a special fertilizer that can promote the expansion of konjac.

[0106] The above is based on the ideal embodiment of the present invention. Through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention. The technical scope of the present invention is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
