Description

Technical Field

[0001] This invention relates to the field of agricultural biostimulant technology, and in particular to a method for preparing mesoporous molecular cleavage photopolymer peptides. Background Technology

[0002] Existing biostimulant products suffer from limitations such as single function, low bioactivity, and limited soil improvement effects. Traditional humic acid and amino acid products have large molecular weights, resulting in low plant absorption and utilization efficiency. While mesoporous materials possess excellent adsorption and slow-release properties, current preparation methods mostly employ chemical synthesis routes, leading to high costs and complex processes. Cellulose residue, as an abundant renewable resource, still suffers from insufficient resource utilization. More importantly, existing preparation technologies lack real-time monitoring and dynamic adjustment mechanisms for the process, resulting in poor product quality stability. They cannot automatically identify the causes of non-compliance based on test results and implement targeted adjustments, hindering continuous and stable industrial production. Summary of the Invention

[0003] Therefore, the present invention provides a method for preparing mesoporous molecular shearing photopolymer peptides to overcome the problems of lack of real-time monitoring and dynamic adjustment capabilities of the process and poor product quality stability in the prior art.

[0004] To achieve the above objectives, this invention provides a method for preparing mesoporous molecular cleavage photopolymer peptides. The method includes: Step S1: The cellulose residue is washed, crushed and dried to obtain pretreated raw material; Step S2: The pretreated raw material is subjected to temperature-controlled pyrolysis under an inert atmosphere to obtain a biochar carrier with a mesoporous structure. Step S3: The biochar carrier is hydrolyzed to break down the cellulose macromolecules into small peptide molecules to obtain a small peptide solution. Step S4: Add a photosensitizer to the small molecule peptide solution and perform light treatment to obtain a photopolymerized peptide solution; Step S5: The photopolymerized peptide solution is dried and pulverized to obtain mesoporous molecular shearing photopolymerized peptide powder. The mesoporous molecular shearing photopolymerized peptide powder is tested for its mesoporous ratio, small molecule peptide content, photosynthetic promoting activity, moisture content, pH, and particle size distribution parameters. The efficacy value of the mesoporous molecular shearing photopolymerized peptide powder is determined based on the mesoporous ratio, small molecule peptide content, and photosynthetic promoting activity. The stability value of the mesoporous molecular shearing photopolymerized peptide powder is determined based on the moisture content, pH, and particle size distribution parameters. Step S6: Determine whether the preparation process of the mesoporous molecular shearing photopolymer peptide powder is qualified based on the efficacy value and the stability value, and if the preparation process is unqualified, determine the reason for the unqualified preparation process based on the relative deviation ratio of the efficacy value and the stability value.

[0005] Further, in step S5, determining the potency value of the mesoporous molecular shear photopolymer peptide powder includes: Step S511: Compare the detected mesoporous ratio with the standard mesoporous ratio threshold and calculate the mesoporous ratio deviation; Step S512: Compare the detected small molecule peptide content with the standard small molecule peptide content threshold, and calculate the small molecule peptide content deviation. Step S513: Compare the detected photosynthetic promoting activity with the standard photosynthetic promoting activity threshold, and calculate the photosynthetic promoting activity deviation; Step S514: The mesopority deviation, small molecule peptide content deviation, and photosynthetic promotion activity deviation are weighted and combined to obtain the efficacy value.

[0006] Further, in step S5, determining the stability value of the mesoporous molecular shear photopolymer peptide powder includes: Step S521: Compare the detected moisture content with the standard moisture content threshold and calculate the moisture content deviation; Step S522: Compare the detected pH with the standard pH threshold range and calculate the pH deviation; Step S523: Compare the detected particle size distribution with the standard particle size distribution threshold, and calculate the particle size distribution deviation; Step S524: The moisture content deviation, pH deviation and particle size distribution deviation are weighted and combined to obtain the stable value.

[0007] Further, in step S6, determining whether the preparation process of the mesoporous molecular shearing photopolymer peptide powder is qualified includes: If the efficacy value is greater than or equal to the first standard threshold and the stability value is greater than or equal to the second standard threshold, then the preparation process is deemed qualified. If the efficacy value is less than the first standard threshold, or the stability value is less than the second standard threshold, the preparation process is deemed unqualified.

[0008] Further, in step S6, the reasons for the failure of the preparation process are determined, including: Divide the effectiveness value by the stability value to obtain the relative deviation ratio; The relative deviation ratio is compared with the first preset range and the second preset range; If the relative deviation ratio is greater than the upper limit of the first preset range, the reason for non-compliance is determined to be a functional activity defect. If the relative deviation ratio is less than the lower limit of the second preset range, the reason for non-compliance is determined to be a physical stability defect. If the relative deviation ratio is between the first preset range and the second preset range, the reason for non-compliance is determined to be a comprehensive defect.

[0009] Furthermore, when the cause of non-compliance is determined to be a functional activity defect, it includes: The deviations of the mesopority, the content of the small molecule peptides, and the photosynthetic promoting activity from their respective standard thresholds were detected. If the deviation of the mesoporous ratio is the largest, then the pyrolysis temperature in the temperature-controlled pyrolysis process is adjusted. If the deviation in the content of the small molecule peptides is the largest, then the acid concentration during the hydrolysis process is adjusted. If the deviation of the photosynthetic promotion activity is the largest, then the concentration of the photosensitizer during the light treatment process is adjusted.

[0010] Furthermore, when the cause of non-compliance is determined to be a physical stability defect, it includes: The deviations of the moisture content, pH, and particle size distribution from their respective standard thresholds were detected. If the deviation in moisture content is the largest, then the drying temperature during the drying and powdering process is adjusted. If the pH deviation is the largest, then adjust the amount of neutralizing agent added to the photopolymer peptide solution; If the deviation in particle size distribution is the largest, then the particle size during the drying and powdering process is adjusted.

[0011] Furthermore, when the cause of nonconformity is determined to be a comprehensive defect, it includes: The deviations of the mesopority, small molecule peptide content, photosynthetic promoting activity, moisture content, pH, and particle size distribution from their respective standard thresholds were detected. Determine the parameter with the largest deviation; If the deviation of the mesopority is the largest, then the pyrolysis temperature in the temperature-controlled pyrolysis process is adjusted, and the drying temperature in the drying and powdering process is adjusted at the same time. If the deviation of the small molecule peptide content is the largest, then the acid concentration in the hydrolysis process is adjusted, and the particle size in the drying and powdering process is adjusted at the same time. If the deviation of the photosynthetic promotion activity is the largest, then the concentration of photosensitizer during the light treatment process is adjusted, and the amount of neutralizer added during the light treatment process is also adjusted. If the deviation of the moisture content is the largest, the drying temperature in the drying and powdering process is adjusted, and the pyrolysis temperature in the temperature-controlled pyrolysis process is adjusted at the same time. If the pH deviation is the largest, the amount of neutralizer added during the light treatment process is adjusted, and the acid concentration during the hydrolysis process is adjusted simultaneously. If the deviation of the particle size distribution is the maximum, the pulverization granularity in the drying and pulverizing process is adjusted, and the acid concentration in the hydrolysis treatment process is adjusted at the same time.

[0012] Further, when adjusting the process parameters, the number of consecutive adjustments for the same parameter shall not exceed three times; If after the same parameter is adjusted three times consecutively, the effectiveness value and the stability value obtained by re-detection still fail to meet the qualification standard, the adjustment is switched to other associated parameters.

[0013] Further, after switching to other associated parameters for adjustment, if the effectiveness value and the stability value still cannot meet the qualification standard after three consecutive switching adjustments, the automatic adjustment is stopped and an alarm message is issued.

[0014] Compared with the prior art, the beneficial effects of the present invention lie in that the present invention establishes a two-layer evaluation system where the effectiveness value is obtained by weighted synthesis of three functional parameters including mesoporosity, small molecule peptide content and photosynthesis-promoting activity, and the stability value is obtained by weighted synthesis of three stability parameters including moisture content, pH and particle size distribution, so as to realize the quantitative characterization of the functional activity and physical stability of the product. On this basis, the specific experimental determination methods for the standard mesoporosity threshold, standard small molecule peptide content threshold, standard photosynthesis-promoting activity threshold, standard moisture content threshold, standard pH threshold range and standard particle size distribution threshold range are clarified, and the mathematical determination methods for each weight coefficient in the effectiveness value and each weight coefficient in the stability value are also clarified, which provides a quantitative basis for subsequent qualification judgment and unqualified cause diagnosis.

[0015] Further, the present invention establishes a dual-threshold judgment mechanism for the effectiveness value and the stability value, which compares the effectiveness value with the first standard threshold in terms of magnitude, and compares the stability value with the second standard threshold in terms of magnitude. Only when both reach or exceed their respective standard thresholds, the product is judged to be qualified, otherwise it is judged to be unqualified. The one-sidedness of single parameter evaluation or empirical judgment in traditional methods is avoided, the rapid and accurate judgment of the qualification of the preparation process is realized, the quality consistency of ex-factory products and the reliability of field application effects are effectively guaranteed, and at the same time, a clear disposal guidance is provided for unqualified products, that is, entering the subsequent diagnosis and adjustment process instead of being directly scrapped, which reduces production losses.

[0016] Furthermore, this invention establishes a deviation localization and targeted adjustment mechanism for functional activity defects. After determining that the cause of non-compliance is a functional activity defect, the deviations of mesoporous area, small molecule peptide content, and photosynthetic promoting activity from their respective standard thresholds are calculated. By comparing the magnitude of the deviations, the main parameters causing the defects are identified, and then the corresponding process steps are adjusted accordingly: when the mesoporous area deviation is the largest, the pyrolysis temperature in the temperature-controlled pyrolysis process is adjusted; when the small molecule peptide content deviation is the largest, the acid concentration in the hydrolysis process is adjusted; and when the photosynthetic promoting activity deviation is the largest, the photosensitizer concentration in the light treatment process is adjusted. This mechanism achieves precise localization of the cause of non-compliance and targeted optimization of process parameters, avoiding process fluctuations and resource waste caused by blindly adjusting multiple parameters.

[0017] Furthermore, this invention establishes a deviation location and targeted adjustment mechanism for physical stability defects. After determining that the cause of non-compliance is a physical stability defect, it calculates the deviations of moisture content, pH, and particle size distribution from their respective standard thresholds. By comparing the magnitude of these deviations, it identifies the main parameters causing the defects and then adjusts the corresponding process steps accordingly: when the moisture content deviation is the largest, it adjusts the drying temperature during the drying and pulverizing process; when the pH deviation is the largest, it adjusts the amount of neutralizing agent added to the photopolymerizing solution; and when the particle size distribution deviation is the largest, it adjusts the particle size during the drying and pulverizing process. This mechanism achieves precise location of the cause of physical stability non-compliance and targeted optimization of process parameters, avoiding process fluctuations caused by blindly adjusting multiple parameters. It effectively controls problems such as excessive moisture, pH deviation, and uneven particle size, ensuring the physical stability and application uniformity of the product during storage and use.

[0018] Furthermore, this invention establishes a deviation localization and synergistic adjustment mechanism for comprehensive defects. After determining that the cause of non-compliance is a comprehensive defect, the deviations of six parameters from their respective standard thresholds are calculated. By comparison, the parameter with the largest deviation is determined, and corresponding dual-parameter synergistic adjustment is performed based on the parameter with the largest deviation: functional activity-related parameters and physical stability-related parameters are adjusted in pairs. Specifically, this includes simultaneously adjusting the pyrolysis temperature and drying temperature when the mesoporous content deviation is the largest; simultaneously adjusting the acid concentration and particle size when the small molecule peptide content deviation is the largest; simultaneously adjusting the photosensitizer concentration and neutralizer addition amount when the photosynthetic promotion activity deviation is the largest; simultaneously adjusting the drying temperature and pyrolysis temperature when the moisture content deviation is the largest; simultaneously adjusting the neutralizer addition amount and acid concentration when the pH deviation is the largest; and simultaneously adjusting the particle size and acid concentration when the particle size distribution deviation is the largest. This mechanism achieves simultaneous treatment of functional activity defects and physical stability defects. The two adjustment operations are executed simultaneously, avoiding repeated trial and error and long-term process deviations caused by step-by-step adjustments, and effectively shortening the adjustment cycle.

[0025] The method for preparing mesoporous molecular cleavage photopolymer peptides according to embodiments of the present invention includes: Step S1: The cellulose residue is washed, crushed and dried to obtain pretreated raw material; Step S2: The pretreated raw material is subjected to temperature-controlled pyrolysis under an inert atmosphere to obtain a biochar carrier with a mesoporous structure. Step S3: The biochar carrier is hydrolyzed to break down the cellulose macromolecules into small peptide molecules to obtain a small peptide solution. Step S4: Add a photosensitizer to the small molecule peptide solution and perform light treatment to obtain a photopolymerized peptide solution; Step S5: The photopolymerized peptide solution is dried and pulverized to obtain mesoporous molecular shearing photopolymerized peptide powder. The mesoporous molecular shearing photopolymerized peptide powder is tested for its mesoporous ratio, small molecule peptide content, photosynthetic promoting activity, moisture content, pH, and particle size distribution parameters. The efficacy value of the mesoporous molecular shearing photopolymerized peptide powder is determined based on the mesoporous ratio, small molecule peptide content, and photosynthetic promoting activity. The stability value of the mesoporous molecular shearing photopolymerized peptide powder is determined based on the moisture content, pH, and particle size distribution parameters. Step S6: Determine whether the preparation process of the mesoporous molecular shearing photopolymer peptide powder is qualified based on the efficacy value and the stability value, and if the preparation process is unqualified, determine the reason for the unqualified preparation process based on the relative deviation ratio of the efficacy value and the stability value.

[0026] In this embodiment of the invention, 100 kg of cellulose residue from crop straw was washed with deionized water at 25°C for 30 minutes to remove mud and impurities, and then centrifuged until the moisture content was below 30%. The residue was then coarsely pulverized in a pulverizer to a particle size of 5-8 mm, and then finely ground in a ball mill for 3 hours to a particle size of 0.2-0.3 mm, with the grinding temperature controlled below 45°C. Finally, the residue was dried in a drying oven at 105°C to constant weight, obtaining a pretreated raw material with a moisture content below 8%. The pretreated raw material was loaded into a pyrolysis furnace, and nitrogen gas was introduced at a flow rate of 100 mL / min to create an inert atmosphere. The pyrolysis temperature was set to 500°C, and the heating rate was 8°C / min. After raising the temperature from room temperature to 500°C, the temperature was maintained for 1.5 hours. After pyrolysis, the residue was naturally cooled to room temperature, and the biochar carrier was collected. The biochar carrier was tested and found to have a specific surface area of ​​235 m² / g, a total pore volume of 0.38 cm³ / g, an average pore size of 12 nm, and a mesoporosity of 65%. 10 kg of the biochar carrier was taken and mixed with 1.0% dilute sulfuric acid solution at a solid-liquid ratio of 1:15. The mixture was then reacted with shaking in a 90°C water bath for 3 hours. After the reaction, calcium hydroxide suspension was added to neutralize to pH 6.0, and the supernatant was collected by centrifugation. The supernatant was found to contain 35% small molecule peptides (molecular weight ≤ 1000 Da). The small molecule peptide solution was concentrated and diluted to a solid content of 8%, and 1.0% of a photosensitizer precursor (riboflavin sodium phosphate) was added. Nitrogen gas was then introduced to remove dissolved oxygen. The solution was irradiated at a wavelength of 500 nm and a light intensity of 80 mW / cm² for 2 hours to obtain a photopolymerized peptide solution. The photosynthetic promoting activity was measured to be 135%. The photopolymerized peptide liquid is fed into a spray drying tower for drying and powdering. The inlet air temperature is 180℃ and the outlet air temperature is 80℃ to obtain mesoporous molecular shearing photopolymerized peptide powder.

[0027] In this embodiment of the invention, the mesoporosity was determined using a nitrogen adsorption method, employing a specific surface area and pore size analyzer to test the powder sample. The nitrogen adsorption-desorption isotherm of the sample was measured at 77K under liquid nitrogen conditions. The pore volume of mesopores (pore size 2-50 nm) was calculated using the BJH method, and the percentage of mesopore volume to total pore volume was used as the mesoporosity. The small molecule peptide content was determined using gel permeation chromatography coupled with multi-angle laser light scattering. The powder sample was prepared into a 1 mg / mL aqueous solution, filtered through a 0.45 μm filter membrane, and injected into the gel permeation chromatography system. A differential refractive index detector and a multi-angle laser light scattering detector were used in combination to calculate the mass percentage of peptides with a molecular weight ≤1000 Da based on the molecular weight distribution map. The photosynthetic promoting activity was determined using a plant photosynthetic rate determination method. Prepare a 100 mg / L aqueous solution from the powder sample. Select uniformly grown plant leaves (such as wheat or rice). Using a photosynthesis meter, measure the net photosynthetic rate of the treatment group (sprayed with the sample solution) and the control group (sprayed with water) under the same light intensity and carbon dioxide concentration. Divide the net photosynthetic rate of the treatment group by the net photosynthetic rate of the control group, then multiply by 100% to obtain the photosynthetic promotion activity value. Moisture content detection: Use the drying method. Accurately weigh 2-5 g of the powder sample, place it in a pre-weighed weighing bottle, and dry it in a drying oven at 105±2℃ until constant weight. Calculate the moisture content percentage based on the mass difference before and after drying. pH detection: Use the potentiometric method. Accurately weigh 1 g of the powder sample, dissolve it in 100 mL of deionized water, stir to dissolve, and let it stand. Measure the pH value using a calibrated pH meter inserted into the solution. Perform three parallel measurements and take the average value. Particle size distribution detection: Use the sieving method. Weigh 50g of powder sample and place it on the top layer of a standard sieve group (sieve aperture sizes are arranged in order of 80 mesh, 100 mesh, 120 mesh, 140 mesh, 160 mesh, 180 mesh, 200 mesh, etc.). Mechanically vibrate and sieve for 15 minutes. Weigh the sample mass on each sieve layer and calculate the mass percentage of each particle size range and the characteristic particle size range.

[0028] Specifically, in step S5, determining the potency value of the mesoporous molecular shear photopolymer peptide powder includes: Step S511: Compare the detected mesoporous ratio with the standard mesoporous ratio threshold and calculate the mesoporous ratio deviation; Step S512: Compare the detected small molecule peptide content with the standard small molecule peptide content threshold, and calculate the small molecule peptide content deviation. Step S513: Compare the detected photosynthetic promoting activity with the standard photosynthetic promoting activity threshold, and calculate the photosynthetic promoting activity deviation; Step S514: The mesopority deviation, small molecule peptide content deviation, and photosynthetic promotion activity deviation are weighted and combined to obtain the efficacy value.

[0029] In this embodiment of the invention, the relative deviation of mesoporous rate is calculated by performing a difference calculation between the detected mesoporous rate and the standard mesoporous rate threshold, and then dividing the resulting difference by the standard mesoporous rate threshold; the relative deviation of small molecule peptide content is calculated by performing a difference calculation between the detected small molecule peptide content and the standard small molecule peptide content threshold; the relative deviation of photosynthetic activity is calculated by performing a difference calculation between the detected photosynthetic activity and the standard photosynthetic activity threshold; the relative deviation of moisture content is calculated by performing a difference calculation between the detected moisture content and the standard moisture content threshold; the relative deviation of pH is calculated by performing a difference calculation between the detected pH and the median value of the standard pH threshold range, and then dividing the absolute value of the difference by half the width of the standard pH threshold range; the relative deviation of particle size distribution is calculated by performing a difference calculation between the detected particle size distribution characteristic value and the standard particle size distribution threshold range, and then dividing the absolute value of the difference by the width of the standard particle size distribution threshold range.

[0030] In this embodiment of the invention, the standard mesoporous rate threshold is determined using a comparative experiment. Multiple groups of biochar carrier samples with different mesoporous rates are prepared and subjected to the same subsequent treatment before soil water and fertilizer retention tests. The ammonia nitrogen adsorption retention rate and water evaporation inhibition rate of each sample in the soil are measured, and the mesoporous rate corresponding to the inflection point of both indicators is taken as the standard mesoporous rate threshold. The standard small molecule peptide content threshold is determined using a plant culture experiment. Multiple groups of samples with different small molecule peptide contents are prepared, diluted to the same concentration, and then used for root irrigation treatment of wheat seedlings. After 7 days of cultivation, root activity and aboveground biomass are measured. The lowest small molecule peptide content at which root activity and biomass show a significant difference from the control group and the difference reaches saturation is taken as the standard small molecule peptide content threshold. The standard photosynthetic promotion activity threshold is determined using a photosynthetic rate verification method. Multiple groups of samples under different photosynthetic treatment conditions are prepared, and their photosynthetic promotion activity values ​​are measured. Simultaneously, field plot experiments are conducted to measure the net photosynthetic rate and yield of the crop. The photosynthetic promotion activity value corresponding to a significant increase in crop net photosynthetic rate and a stable inflection point in yield increase is used as the standard photosynthetic promotion activity threshold.

[0031] In this embodiment of the invention, the weighting coefficients in the efficacy value are determined using either the analytic hierarchy process (AHP) or principal component analysis (PCA). Specifically, data on mesoporous area, small molecule peptide content, and photosynthetic promoting activity of multiple batches of normal production samples are collected. Using plant growth promotion effect as the evaluation index, multiple linear regression analysis is performed, and the weighting coefficients are determined based on the contribution of each parameter to the plant growth promotion effect. Among these, photosynthetic promoting activity has the greatest direct promoting effect on plant growth and is assigned the highest weight; mesoporous area mainly promotes plant growth indirectly by improving the soil environment and is assigned a medium weight; and small molecule peptide content provides direct nutrient supplementation and is assigned a basic weight.

[0032] Specifically, in step S5, determining the stability value of the mesoporous molecular shear photopolymer peptide powder includes: Step S521: Compare the detected moisture content with the standard moisture content threshold and calculate the moisture content deviation; Step S522: Compare the detected pH with the standard pH threshold range and calculate the pH deviation; Step S523: Compare the detected particle size distribution with the standard particle size distribution threshold, and calculate the particle size distribution deviation; Step S524: The moisture content deviation, pH deviation and particle size distribution deviation are weighted and combined to obtain the stable value.

[0033] In this embodiment of the invention, a standard moisture content threshold is set. The difference between the detected moisture content and the standard moisture content threshold is calculated, and the difference is divided by the standard moisture content threshold to calculate the relative deviation of the moisture content. A standard pH threshold range is set. The difference between the detected pH and the median value of the standard pH threshold range is calculated, and the absolute value of the difference is divided by half the width of the standard pH threshold range to calculate the relative pH deviation. A standard particle size distribution threshold range is set. The difference between the detected particle size distribution characteristic value and the standard particle size distribution threshold range is calculated, and the absolute value of the difference is divided by the width of the standard particle size distribution threshold range to calculate the relative particle size distribution deviation. Appropriate weighting coefficients are assigned to the moisture content deviation, pH deviation, and particle size distribution deviation, respectively. The three weighted deviations are summed to obtain a stable value. The weighting coefficient for moisture content deviation is determined based on the degree of influence of moisture on the degradation of active ingredients; the weighting coefficient for pH deviation is determined based on the degree of influence of pH on the stability of active ingredients; and the weighting coefficient for particle size distribution deviation is determined based on the degree of influence of particle size on the suspension and dispersion performance of the product. The sum of all weighting coefficients is 1.

[0034] In this embodiment of the invention, the standard moisture content threshold is determined using an accelerated stability test. Powder samples with different moisture contents are sealed and placed in a constant temperature and humidity chamber at 40°C and 75% relative humidity for 90 days of accelerated storage. The retention rate of small molecule peptides and photosynthetic promoting activity is measured every 15 days. The highest allowable moisture content that ensures a ≥90% retention rate of active ingredients within 90 days is taken as the standard moisture content threshold. The standard pH threshold is determined using a plant tolerance test. The powder is prepared into a 1% aqueous solution, and the pH value is adjusted to different values. Germination tests are then conducted on seeds. The seed germination rate and root elongation are measured. The pH range corresponding to a germination rate ≥85% and a root elongation inhibition rate ≤20% is taken as the standard pH threshold range. The standard particle size distribution threshold is determined using a suspension sedimentation test. Powder samples with different particle size distributions are prepared and formulated into 1% aqueous suspensions. After standing for 30 minutes, the content of small molecule peptides in the upper layer of the suspension is measured. The standard particle size distribution threshold is the range of particle size distribution that ensures good suspension uniformity and minimizes sedimentation loss of active ingredients.

[0035] In this embodiment of the invention, the method for determining the weighting coefficients in the stability values ​​is as follows: accelerated storage experiments combined with orthogonal experimental design are used. Specifically, samples with different moisture contents, pH levels, and particle size distributions are prepared, and the retention rates of active ingredients are measured under the same accelerated storage conditions. The influence of moisture content, pH level, and particle size distribution on the retention rate of active ingredients is calculated, and their respective weighting coefficients are determined based on the magnitude of their influence. Among these, moisture content has the greatest impact on storage stability and is assigned the highest weight; pH level is second; and particle size distribution is third.

[0036] This invention establishes a two-tiered evaluation system to quantitatively characterize the functional activity and physical stability of products by weighting and synthesizing three functional parameters—mesoporosity, small molecule peptide content, and photosynthetic promotion activity—to obtain an efficacy value, and three stability parameters—moisture content, pH, and particle size distribution—to obtain a stability value. Based on this, specific experimental methods for determining the standard mesoporosity threshold, standard small molecule peptide content threshold, standard photosynthetic promotion activity threshold, standard moisture content threshold, standard pH threshold, and standard particle size distribution threshold range are clearly defined. Furthermore, the mathematical methods for determining the weighting coefficients in the efficacy value and the stability value are clarified, providing a quantitative basis for subsequent qualification judgment and diagnosis of non-compliance reasons.

[0037] Specifically, in step S6, determining whether the preparation process of the mesoporous molecular shearing photopolymer peptide powder is qualified includes: If the efficacy value is greater than or equal to the first standard threshold and the stability value is greater than or equal to the second standard threshold, then the preparation process is deemed qualified. In response to the potency value being less than the first standard threshold, or the stability value being less than the second standard threshold, it is determined that the preparation process is unqualified.

[0038] In the embodiment of the present invention, a first standard threshold and a second standard threshold are set. The potency value calculated in step S514 is compared with the first standard threshold, and the stability value calculated in step S524 is compared with the second standard threshold. When the potency value is greater than or equal to the first standard threshold, and the stability value is simultaneously greater than or equal to the second standard threshold, it is determined that the preparation process of the batch of mesoporous molecule-sheared photopolymerized peptide powder is qualified, and the product is permitted to leave the factory for sale. When the potency value is less than the first standard threshold, or the stability value is less than the second standard threshold, or both are less than their respective standard thresholds, it is determined that the preparation process of the batch of mesoporous molecule-sheared photopolymerized peptide powder is unqualified, the product shall not leave the factory, and needs to enter the subsequent unqualified cause diagnosis and process adjustment process. Wherein, both the first standard threshold and the second standard threshold are determined by a statistical method. Specifically, data of multiple batches of qualified products that are normally produced and have been verified to have good effects through field trials are collected, the distribution ranges of the potency value and the stability value of each batch are calculated, the lower limit of the potency value distribution of the qualified products is taken as the first standard threshold, and the lower limit of the stability value distribution of the qualified products is taken as the second standard threshold.

[0039] The present invention establishes a dual-threshold judgment mechanism for the potency value and the stability value, compares the magnitude of the potency value with the first standard threshold, and compares the magnitude of the stability value with the second standard threshold. Only when both reach or exceed their respective standard thresholds is it judged as qualified, otherwise it is judged as unqualified. The one-sidedness of single-parameter evaluation or empirical judgment in traditional methods is avoided, rapid and accurate judgment of the qualification of the preparation process is realized, the quality consistency of ex-factory products and the reliability of field application effects are effectively guaranteed, and at the same time, a clear disposal guidance is provided for unqualified products, that is, entering the subsequent diagnosis and adjustment process instead of direct scrapping, which reduces production losses.

[0040] Specifically, in step S6, determining the cause of unqualifiedness of the preparation process includes: Dividing the potency value by the stability value to obtain the relative deviation ratio; Comparing the relative deviation ratio with a first preset range and a second preset range; If the relative deviation ratio is greater than the upper limit value of the first preset range, it is determined that the cause of unqualifiedness is functional activity defect; If the relative deviation ratio is less than the lower limit value of the second preset range, it is determined that the cause of unqualifiedness is physical stability defect; If the relative deviation ratio is located between the first preset range and the second preset range, it is determined that the cause of unqualifiedness is comprehensive defect.

[0041] In this embodiment of the invention, the efficacy value calculated in step S514 is divided by the stability value calculated in step S524 to obtain a relative deviation ratio. A first preset range and a second preset range are set, wherein the upper limit of the first preset range is greater than 1, and the lower limit of the second preset range is less than 1. The upper limit of the first preset range and the lower limit of the second preset range are symmetrical about 1 or inversely related. The calculated relative deviation ratio is compared with the first preset range and the second preset range: if the relative deviation ratio is greater than the upper limit of the first preset range, it indicates that the efficacy value is relatively high and the stability value is relatively low. The reason for non-compliance is determined to be a functional activity defect, meaning that although the product performs well in terms of functional indicators, its physical stability is insufficient, and there may be a risk of rapid degradation of the active ingredients during storage. If the relative deviation ratio is less than the lower limit of the second preset range, it indicates that the stability value is relatively high and the efficacy value is relatively low. The reason for non-compliance is determined to be a physical stability defect, meaning that although the product meets the stability indicators, its functional activity does not meet the requirements and cannot provide the expected plant growth-promoting effect.

[0042] If the relative deviation ratio falls between the lower limit of the second preset range and the upper limit of the first preset range, it indicates that both the efficacy value and stability value deviate to varying degrees. The cause of non-compliance is then determined to be a comprehensive defect, meaning that both the product's functional activity and physical stability fail to meet requirements, necessitating a comprehensive investigation of all process stages. The first and second preset ranges are determined using statistical methods or empirical rules. Specifically, efficacy and stability value data from multiple batches of non-conforming products are collected, the relative deviation ratio for each batch is calculated, and the correlation between the ratio distribution and actual process problems is analyzed. A critical ratio value that effectively distinguishes between functional activity defects, physical stability defects, and comprehensive defects is used as the boundary of the preset range.

[0043] Specifically, when the reason for non-compliance is determined to be a functional activity defect, it includes: The deviations of the mesopority, the content of the small molecule peptides, and the photosynthetic promoting activity from their respective standard thresholds were detected. If the deviation of the mesoporous ratio is the largest, then the pyrolysis temperature in the temperature-controlled pyrolysis process is adjusted. If the deviation in the content of the small molecule peptides is the largest, then the acid concentration during the hydrolysis process is adjusted. If the deviation of the photosynthetic promotion activity is the largest, then the concentration of the photosensitizer during the light treatment process is adjusted.

[0044] In this embodiment of the invention, the deviations of mesoporous rate, small molecule peptide content, and photosynthetic promoting activity from their respective standard thresholds are calculated. Specifically, the difference between the detected mesoporous rate and the standard mesoporous rate threshold is calculated to obtain the mesoporous rate deviation; the difference between the detected small molecule peptide content and the standard small molecule peptide content threshold is calculated to obtain the small molecule peptide content deviation; and the difference between the detected photosynthetic promoting activity and the standard photosynthetic promoting activity threshold is calculated to obtain the photosynthetic promoting activity deviation.

[0045] Compare the magnitudes of the three deviations mentioned above to determine the parameter with the largest deviation: If the mesoporous rate deviation is the largest, it indicates that the mesoporous structure of the product is insufficiently constructed, and the low mesoporous rate leads to insufficient soil amendment function. In this case, the temperature-controlled pyrolysis process should be adjusted, specifically the pyrolysis temperature. When the mesoporous rate is below the standard threshold, the pyrolysis temperature should be appropriately increased to promote the formation of more mesoporous structures; when the mesoporous rate is above the upper limit of the standard threshold, the pyrolysis temperature should be appropriately decreased to avoid excessive pore expansion leading to structural collapse. If the small molecule peptide content deviation is the largest, it indicates that the hydrolysis and degradation of cellulose macromolecules is insufficient, and the amount of small molecule peptides generated is insufficient. In this case, the hydrolysis process should be adjusted, specifically the acid concentration. When the small molecule peptide content is below the standard threshold, the acid concentration should be appropriately increased to enhance the hydrolysis intensity and promote the conversion of cellulose macromolecules into small molecule peptides; when using an enzymatic hydrolysis process, the amount of enzyme added or the enzymatic hydrolysis time should be adjusted accordingly.

[0046] If the deviation in photosynthetic promoting activity is the largest, it indicates insufficient photosynthesis and low efficiency in introducing photosensitizing groups. In this case, the light treatment process should be adjusted, specifically the photosensitizer concentration. When the photosynthetic promoting activity is below the standard threshold, the photosensitizer concentration should be appropriately increased to enhance the photochemical reaction intensity and promote the introduction of more photosynthetic active groups. Each adjustment should target one parameter at a time, with the adjustment step size determined by the degree of deviation; the larger the deviation, the larger the adjustment range. After adjustment, samples should be resampled and tested, and the efficacy value and various deviations recalculated until the efficacy value reaches the first standard threshold requirement. If the efficacy value still fails to meet the standard after three consecutive adjustments of the same parameter, other related parameters should be switched for adjustment.

[0047] This invention establishes a deviation localization and targeted adjustment mechanism for functional activity defects. After determining that the cause of non-compliance is a functional activity defect, it calculates the deviations of mesoporous area, small molecule peptide content, and photosynthetic promoting activity from their respective standard thresholds. By comparing the magnitude of these deviations, the main parameters causing the defects are identified, and then corresponding process steps are adjusted accordingly: when the mesoporous area deviation is the largest, the pyrolysis temperature in the temperature-controlled pyrolysis process is adjusted; when the small molecule peptide content deviation is the largest, the acid concentration in the hydrolysis process is adjusted; and when the photosynthetic promoting activity deviation is the largest, the photosensitizer concentration in the light treatment process is adjusted. This mechanism achieves precise localization of the cause of non-compliance and targeted optimization of process parameters, avoiding process fluctuations and resource waste caused by blindly adjusting multiple parameters.

[0048] Specifically, when the cause of non-compliance is determined to be a physical stability defect, it includes: The deviations of the moisture content, pH, and particle size distribution from their respective standard thresholds were detected. If the deviation in moisture content is the largest, then the drying temperature during the drying and powdering process is adjusted. If the pH deviation is the largest, then adjust the amount of neutralizing agent added to the photopolymer peptide solution; If the deviation in particle size distribution is the largest, then the particle size during the drying and powdering process is adjusted.

[0049] In this embodiment of the invention, the deviations of moisture content, pH, and particle size distribution from their respective standard thresholds are calculated. Specifically, the moisture content deviation is obtained by calculating the difference between the detected moisture content and the standard moisture content threshold; the pH deviation is obtained by calculating the difference between the detected pH and the median value of the standard pH threshold range; and the particle size distribution deviation is obtained by calculating the difference between the detected particle size distribution characteristic value and the standard particle size distribution threshold range. The magnitudes of these three deviations are compared to determine the parameter with the largest deviation: if the moisture content deviation is the largest, it indicates that the product is not sufficiently dried or has absorbed moisture during storage. Excessive moisture content may lead to hydrolysis and degradation of active ingredients and product agglomeration and deterioration. Therefore, the drying and powdering process is adjusted, specifically the drying temperature. When the moisture content is higher than the standard threshold, the drying temperature is appropriately increased or the drying time is extended to enhance the dehydration effect; when the moisture content is too low, the drying temperature is appropriately decreased to avoid over-drying causing thermal damage to active ingredients or electrostatic agglomeration of the product.

[0050] If the pH deviation is the largest, it indicates insufficient neutralization and adjustment of the photopolymer solution. A pH deviation from the appropriate range may lead to inactivation of active ingredients and pose a risk of plant irritation. Therefore, the photopolymer solution should be adjusted, specifically by adjusting the amount of neutralizing agent added. When the pH is below the lower limit of the standard threshold range, the amount of neutralizing agent added should be appropriately increased to raise the pH value; when the pH is above the upper limit of the standard threshold range, the amount of neutralizing agent added should be appropriately reduced to lower the pH value. If the particle size distribution deviation is the largest, it indicates improper control of the grinding or sieving process. An excessively wide particle size distribution or a characteristic particle size deviating from the target range may lead to poor product suspension and dispersibility, and uneven application. Therefore, the drying and powdering process should be adjusted, specifically by adjusting the grinding particle size. When the particle size is too large, increase the grinding intensity or extend the grinding time; when the particle size is too small, decrease the grinding intensity or adjust the sieving parameters. Each adjustment should focus on one parameter at a time, with the adjustment step size determined by the degree of deviation; the larger the deviation, the larger the adjustment range. After adjustment, resampling and testing should be performed, and the stable value and various deviations should be recalculated until the stable value reaches the second standard threshold requirement. If the stable value still fails to meet the standard after adjusting the same parameter three times consecutively, switch to other related parameters for adjustment.

[0051] This invention establishes a deviation location and targeted adjustment mechanism for physical stability defects. After determining that the cause of non-compliance is a physical stability defect, it calculates the deviations of moisture content, pH, and particle size distribution from their respective standard thresholds. By comparing the magnitude of these deviations, the main parameters causing the defects are identified, and corresponding process steps are adjusted accordingly: when the moisture content deviation is the largest, the drying temperature in the drying and pulverizing process is adjusted; when the pH deviation is the largest, the amount of neutralizing agent added to the photopolymerizing solution is adjusted; and when the particle size distribution deviation is the largest, the particle size in the drying and pulverizing process is adjusted. This mechanism achieves precise location of the cause of physical stability non-compliance and targeted optimization of process parameters, avoiding process fluctuations caused by blindly adjusting multiple parameters. It effectively controls problems such as excessive moisture, pH deviation, and uneven particle size, ensuring the physical stability and application uniformity of the product during storage and use.

[0052] Specifically, when the cause of nonconformity is determined to be a comprehensive defect, it includes: The deviations of the mesopority, small molecule peptide content, photosynthetic promoting activity, moisture content, pH, and particle size distribution from their respective standard thresholds were detected. Determine the parameter with the largest deviation; If the deviation of the mesopority is the largest, then the pyrolysis temperature in the temperature-controlled pyrolysis process is adjusted, and the drying temperature in the drying and powdering process is adjusted at the same time. If the deviation of the small molecule peptide content is the largest, then the acid concentration in the hydrolysis process is adjusted, and the particle size in the drying and powdering process is adjusted at the same time. If the deviation of the photosynthetic promotion activity is the largest, then the concentration of photosensitizer during the light treatment process is adjusted, and the amount of neutralizer added during the light treatment process is also adjusted. If the deviation of the moisture content is the largest, the drying temperature in the drying and powdering process is adjusted, and the pyrolysis temperature in the temperature-controlled pyrolysis process is adjusted at the same time. If the pH deviation is the largest, the amount of neutralizer added during the light treatment process is adjusted, and the acid concentration during the hydrolysis process is adjusted simultaneously. If the deviation in particle size distribution is the largest, the particle size during the drying and pulverizing process is adjusted, and the acid concentration during the hydrolysis process is also adjusted.

[0053] In this embodiment of the invention, the deviations of mesopority, small molecule peptide content, photosynthetic promotion activity, moisture content, pH, and particle size distribution from their respective standard thresholds are calculated. Specifically, the differences between each parameter obtained by detection and its corresponding standard threshold are calculated to obtain the deviations for each parameter. The magnitudes of the above six deviations are compared to determine the parameter with the largest deviation, and corresponding synergistic adjustments are performed based on the parameter with the largest deviation: if the deviation of mesopority is the largest, it indicates that the main problem is the construction of the mesoporous structure, accompanied by physical stability issues. In this case, the pyrolysis temperature during the temperature-controlled pyrolysis process is adjusted to improve the mesoporous structure, and the drying temperature during the drying and powdering process is simultaneously adjusted to improve physical stability. If the deviation of small molecule peptide content is the largest, it indicates that the main problem is the hydrolysis treatment, accompanied by physical stability issues. In this case, the acid concentration during the hydrolysis treatment process is adjusted to enhance the hydrolysis efficiency and promote the generation of small molecule peptides, and the particle size during the drying and powdering process is simultaneously adjusted to improve the particle size distribution.

[0054] If the deviation in photosynthetic promotion activity is the largest, it indicates a primary problem with photosynthetic treatment, accompanied by pH issues. In this case, adjust the concentration of the photosensitizer during the photosynthetic treatment process to enhance the photochemical reaction intensity, and simultaneously adjust the amount of neutralizer added during the photosynthetic treatment process to adjust the pH to a suitable range. If the deviation in moisture content is the largest, it indicates a primary problem with drying, accompanied by mesoporous structure issues. In this case, adjust the drying temperature during the drying and powdering process to control the moisture content, and simultaneously adjust the pyrolysis temperature during the temperature-controlled pyrolysis process to improve the mesoporous structure. If the deviation in pH is the largest, it indicates a primary problem with neutralization adjustment, accompanied by hydrolysis issues. In this case, adjust the amount of neutralizer added during the photosynthetic treatment process to adjust the pH, and simultaneously adjust the acid concentration during the hydrolysis process to optimize the hydrolysis conditions. If the deviation in particle size distribution is the largest, it indicates a primary problem with pulverization, accompanied by hydrolysis issues. In this case, adjust the pulverization particle size during the drying and powdering process to improve the particle size distribution, and simultaneously adjust the acid concentration during the hydrolysis process to optimize the generation of small molecule peptides. In the aforementioned coordinated adjustment, two adjustment operations are performed simultaneously. The adjustment step size for each parameter is determined based on its respective deviation; the larger the deviation, the larger the adjustment amplitude. After adjustment, resampling and testing are performed, and the effectiveness value, stability value, and various deviations are recalculated until the effectiveness value and stability value both reach their respective standard threshold requirements. If the same combination still fails to meet the standard after three consecutive adjustments, the adjustment is switched to other related parameter combinations.

[0055] This invention establishes a deviation localization and synergistic adjustment mechanism for comprehensive defects. After determining that the cause of non-compliance is a comprehensive defect, it calculates the deviations of six parameters from their respective standard thresholds. By comparison, it identifies the parameter with the largest deviation and performs corresponding dual-parameter synergistic adjustment based on this parameter. Specifically, it pairs and adjusts functional activity-related parameters with physical stability-related parameters. This includes simultaneously adjusting pyrolysis and drying temperatures when the mesoporous content deviation is largest; simultaneously adjusting acid concentration and particle size when the small molecule peptide content deviation is largest; simultaneously adjusting photosensitizer concentration and neutralizer dosage when the photosynthetic promotion activity deviation is largest; simultaneously adjusting drying and pyrolysis temperatures when the moisture content deviation is largest; simultaneously adjusting neutralizer dosage and acid concentration when the pH deviation is largest; and simultaneously adjusting particle size and acid concentration when the particle size distribution deviation is largest. This mechanism achieves simultaneous management of functional activity and physical stability defects. The two adjustment operations are executed simultaneously, avoiding repeated trial and error and prolonged process deviations caused by step-by-step adjustments, effectively shortening the adjustment cycle.

[0056] Specifically, when adjusting process parameters, the same parameter should not be adjusted more than three times consecutively; If the efficacy and stability values ​​obtained after three consecutive adjustments of the same parameter still fail to meet the qualification standards, then switch to other related parameters for adjustment.

[0057] Specifically, if after switching to other related parameters for adjustment, the effectiveness and stability values ​​still cannot reach the qualified standards after three consecutive switching adjustments, the automatic adjustment will stop and an alarm message will be issued.

[0058] In this embodiment of the invention, a single adjustment step size is set for each adjustment parameter. After each adjustment, resampling and testing are performed, and the efficacy and stability values ​​are recalculated. The number of consecutive adjustments to the same parameter is counted. When a parameter is identified as the adjustment target, the count is incremented with each adjustment. If the efficacy and stability values ​​obtained after adjustment meet the qualification standards, the count is reset to zero and the adjustment process ends. If the efficacy and stability values ​​obtained after three consecutive adjustments to the same parameter still do not meet the qualification standards, it indicates that the adjustment of this parameter can no longer improve product quality. Therefore, further adjustment of this parameter is stopped, and the system automatically switches to other related parameters for adjustment. The switching rules are as follows: if the original adjustment parameter is a parameter related to functional activity defects, the system switches to other parameters under the same defect type; if the original adjustment parameter is a parameter related to physical stability defects, the system switches to other parameters under the same defect type; if it is a synergistic adjustment in a comprehensive defect, the system switches to other parameter combinations.

[0059] Adjustments are made to the new parameters or combinations of parameters after the switch, and the system also performs a continuous adjustment count. If, after three consecutive adjustments, the effectiveness and stability values ​​still fail to meet the pass standards, it indicates that the current adjustment strategy cannot solve the product quality problem. The system determines that the non-compliance is caused by systemic reasons such as equipment failure or batch defects in raw materials, and stops automatic adjustment, issuing an alarm message to notify the operator for manual intervention. Alarm messages can be issued in ways including but not limited to: displaying alarm prompts on the control interface, issuing audible and visual alarm signals, and sending SMS or push notifications to management personnel. The alarm message includes: the product number of the current batch, the specific values ​​of each test parameter, the adjustment record already executed (including adjustment parameters, number of adjustments, and adjustment range), and suggested directions for manual troubleshooting.
