Description

Technical Field

[0001] The invention relates to the technical field of fertilization scheme analysis, and in particular to an analysis method, equipment and storage medium for combining polyglutamic acid with compound fertilizer. Background Art

[0002] Compound fertilizer is a kind of fertilizer containing two or more essential nutrients for plants, usually including nitrogen (N), phosphorus (P), and potassium (K). The basic principle of compound fertilizer production is to mix different raw materials in a certain proportion through chemical reaction, physical mixing and other methods to make fertilizer that meets specific needs. The key to compound fertilizer production lies in the accuracy of the formula, because different crops have different requirements for nutrients, and the wrong formula may cause poor growth or even death of crops. The formulation needs to take into account factors such as crop type, growth stage, and soil conditions.

[0003] Polyglutamic acid (γ-PGA), also known as natto gum and polyglutamic acid, is a water-soluble, biodegradable, non-toxic biopolymer material produced by microbial fermentation. It is a type of homopolymer amino acid formed by the polymerization of glutamic acid monomers through amide bonds, and has the advantages of super strong adsorption and non-toxicity.

[0004] In 1933, γ-polyglutamic acid was first discovered in natto fermentation products and is the main component of natto's viscous colloid. In 1942, Bovarnick discovered that γ-PGA, as a fermentation product, can be freely secreted into the growth medium of Bacillus subtilis. People found that many Bacillus can produce γ-PGA outside the cell. Polyglutamic acid is used as an adjuvant for synergistic fertilizers. After adding it, the fertilizer utilization rate can be increased from 30-35% to 40-50%, and the fertilizer utilization rate is increased by 8% on average. Generally, it can increase the yield of crops by 10-35%, and the yield of root crops can increase by more than 30-60%.

[0005] The fertilization scheme combining polyglutamic acid and compound fertilizer is a popular technical research direction at present, but there is currently a lack of effective analytical methods to analyze the effectiveness of different combined fertilization schemes. Summary of the invention

[0006] The purpose of the present invention is to provide an analysis method, equipment and storage medium for combining polyglutamic acid and compound fertilizer, which can automatically calculate the best fertilization plan for combining polyglutamic acid and compound fertilizer according to the set target formula and crop needs, and provide detailed formula ratios and cost estimates, which can not only ensure that crops obtain the required nutrition, but also minimize production costs.

[0007] The above technical purpose of the present invention is achieved by the following technical scheme: an analytical method combining polyglutamic acid and compound fertilizer, comprising the following steps:

Different crops have different nutrient absorption ratios and demand characteristics, and the same crop has different absorption ratios and demand characteristics at different growth stages.

[0018] The present invention is further configured as follows: in step S4, for the crops to be analyzed, in each growth cycle and critical period, a variety of combinations of polyglutamic acid and compound fertilizers are designed, such as physical mixing, chemical chelation, and coating treatment, and specific process parameters of each scheme are determined.

A person of ordinary skill in the art can know that with the evolution of the automatic organic fertilizer preparation device and the emergence of new business scenarios, the technical solution provided by the embodiment of the present invention is also applicable to similar technical problems.

[0044] The present invention uses historical construction project data and tower crane basic data to train a trained tower crane selection model, and uses machine learning to achieve self-tuning of tower crane selection, which can improve the efficiency of tower crane selection, improve the matching degree between tower crane and target project, and facilitate the selection of a suitable tower crane solution for the target construction project. The following is a detailed description in conjunction with specific embodiments.

[0045] In this embodiment, the analysis method for combining polyglutamic acid and compound fertilizer will be described from the perspective of the analysis method for combining polyglutamic acid and compound fertilizer. The analysis method for combining polyglutamic acid and compound fertilizer can be specifically integrated into the automatic system 100 for preparing organic fertilizer.

[0046] See also Figure 2 , Figure 2 The present invention is a schematic flow chart of an example of an analytical method for combining polyglutamic acid and compound fertilizer. The method combines polyglutamic acid (PGA) with compound fertilizer to increase the functionality of the compound fertilizer. The advantages and disadvantages of various combination schemes and usage scenarios can be analyzed by software algorithms to ensure that the fertilization scheme most suitable for specific crops and soil conditions is selected. Specifically, the analytical method for combining polyglutamic acid and compound fertilizer includes the following steps:

[0047] S1, determine the crops to be analyzed, such as rice, wheat or corn;

[0048] S2, determining the growth cycle and critical period of the crop to be analyzed;

[0049] S3, determining the environmental conditions and nutrient absorption characteristics of the crop growth, and selecting appropriate fertilizer types and fertilization methods according to the environmental conditions and nutrient absorption characteristics of the crop growth to improve the stress resistance of the crop;

[0050] S4, generating combined fertilization schemes for different growth cycles and different critical periods according to the selected suitable fertilizer types and fertilization methods, wherein the combined fertilization scheme is a fertilization scheme combining polyglutamic acid and compound fertilizer, wherein a plurality of combined fertilization schemes are generated for each growth cycle and critical period;

[0051] S5, evaluating the advantages and disadvantages of the combined fertilization scheme, and determining the best combined fertilization scheme for each growth cycle and critical period;

[0052] S6, verifying the best combined fertilization scheme and obtaining verification analysis results.

[0053] Furthermore, in step S2, the growth cycle of the crops includes seed germination period, seedling period, vegetative growth period, reproductive growth period and maturity period; the critical period of the crops is the critical period in each growth stage of the crops, including tillering period, jointing period, heading period, flowering period and fruiting period, and the demand for nutrients of crops in these periods is often greater.

[0054] Furthermore, in step S3, when determining the environmental conditions for the growth of the crop (such as soil type, climate characteristics, irrigation conditions, etc.), soil type, pH value, organic matter content, and moisture status factors are considered to analyze the soil's demand and response to fertilizers;

[0055] When determining the nutrient absorption characteristics of the crop growth, the nutrient absorption characteristics of different crops and the same crop at different growth stages are analyzed. Different crops have different absorption ratios and demand characteristics for nutrients. For example, rice has a greater demand for nitrogen, phosphorus, and potassium, while tomatoes have the highest demand for potassium, followed by nitrogen, and less phosphorus. The same crop also has different absorption ratios and demand characteristics at different growth stages. For example, rice is topdressed with nitrogen fertilizer during the tillering stage to promote tillering, and nitrogen, phosphorus, potassium, etc. are topdressed during the jointing stage to promote panicle length and spikelet development.

[0056] Furthermore, in step S4, for the crops to be analyzed, in each growth cycle and critical period, a variety of combinations of polyglutamic acid and compound fertilizers are designed, such as physical mixing, chemical chelation, and coating treatment, and specific process parameters of each solution are determined.

[0057] Among them, physical mixing is the simplest combination method, that is, directly mixing polyglutamic acid and compound fertilizer in a certain proportion. This method is simple and easy, low in cost, and suitable for most compound fertilizer production lines.

[0058] Specific process parameters of physical mixing: Raw material ratio: Determine the mixing ratio of polyglutamic acid and compound fertilizer according to crop needs and soil conditions. It is generally recommended to add 6-10kg / ton of polyglutamic acid fermentation liquid or a corresponding amount of polyglutamic acid powder to the compound fertilizer.

[0059] Mixing equipment: Use a twin-shaft paddle mixer or drum mixer to ensure a uniform mix.

[0060] Mixing time: According to the equipment performance and raw material characteristics, the mixing time is generally controlled within 10-20 minutes.

[0061] For example, in Sichuan watermelon base, 300g / mu of 5% polyglutamic acid stock solution was mixed with compound fertilizer and then applied, which increased the fruit setting rate and fruit expansion speed of watermelon and finally increased the yield by 20%.

[0062] Chemical chelation is the process of combining polyglutamic acid with nutrients (such as calcium, magnesium, etc.) in compound fertilizers through chemical reactions to form stable chelates. This combination can significantly improve the stability and utilization of nutrients.

[0063] Specific process parameters of chemical chelation:

[0064] Raw material selection: polyglutamic acid fermentation broth, calcium nitrate tetrahydrate (or other nutrient elements that need to be chelated).

[0065] Fermentation broth treatment: Heat the polyglutamic acid fermentation broth to 60-80°C, adjust the pH to 3-3.5, and maintain for 6-8 hours to degrade into polyglutamic acid of suitable molecular weight. Chelation reaction: Mix the treated polyglutamic acid with calcium nitrate tetrahydrate in a certain proportion, adjust the pH to 6-7, and stir the reaction for 60-120 minutes. Additives: Surfactants (such as sodium dodecylbenzene sulfonate) and preservatives (such as potassium sorbate) can be added as needed.

[0066] For example, the preparation of polyglutamic acid chelated calcium fertilizer combines polyglutamic acid with calcium ions through chemical chelation, which improves the absorption efficiency and fertilizer effect of calcium fertilizer. The application of this fertilizer in Xinjiang cantaloupe and grape bases has significantly improved the aroma and sweetness of the fruit.

[0067] Coating treatment is to coat the surface of compound fertilizer particles with a layer of polyglutamic acid film to form a slow-release effect and prolong the fertilizer effect. This method is suitable for crops that require long-term fertilizer supply.

[0068] Specific process parameters of coating treatment:

[0069] Coating material: polyglutamic acid coating agent, which can be polyglutamic acid solution or powder. Coating process: send compound fertilizer particles into the coating system. Spray polyglutamic acid coating agent on the surface of particles, and add anti-caking agent at the same time; make the coating agent evenly adhere to the surface of particles and solidify by rotating, heating or spraying. Coating thickness: adjusted according to the type of fertilizer and crop needs, generally controlled within a certain range to ensure the slow release effect.

[0070] For example, the application of polyglutamic acid coated compound fertilizer in Xinjiang cotton base has improved the cotton's fruit setting rate and resistance to Verticillium wilt by stably releasing nutrients.

[0071] What needs to be understood is that by using compound fertilizer production formula calculation software, the raw material data and target formula requirements are input to automatically calculate the optimal ratio of each raw material.

[0072] Compound fertilizer production formula calculation software can help farmers, agricultural enterprises and fertilizer manufacturers improve production efficiency, reduce costs and optimize crop nutrition management. Through this software, users can input the composition and cost of various raw materials. The software will automatically calculate the best production formula based on the set target formula and crop needs, and provide detailed formula ratios and cost estimates. This not only ensures that crops get the nutrients they need, but also minimizes production costs. For example, for crops that require specific ratios of nitrogen, phosphorus and potassium, the software can accurately calculate the best raw material ratio, avoiding the tediousness and errors of manual calculations.

[0073] Among them, the principles that can be adopted in formulating fertilization plans are:

[0074] Combination of base fertilizer and top dressing: base fertilizer is mainly organic fertilizer, combined with an appropriate amount of chemical fertilizer to provide a long-lasting nutrient supply for crops; top dressing is supplemented during the critical period according to the growth needs of crops.

[0075] Staged fertilization: Fertilizers are applied to the soil in stages according to the crop growth cycle and nutrient demand characteristics to ensure that crops can obtain sufficient nutrients at different growth stages.

[0076] Balanced fertilization: focus on the balanced supply of nutrients such as nitrogen, phosphorus, potassium, etc., while supplementing medium and trace elements to meet the needs of comprehensive crop growth.

[0077] Scientific fertilization methods: Use appropriate fertilization methods, such as furrow fertilization, hole fertilization, foliar spraying, etc., to improve fertilizer utilization and reduce nutrient loss.

[0078] Furthermore, step S5 specifically includes the following steps:

[0079] S51, establish a fertilizer effect prediction model based on crop growth model and soil nutrient conversion model;

[0080] S52, input the parameters of different combination schemes into the model to simulate the process of fertilizer dissolution, release and absorption in the soil and predict the impact on crop growth;

[0081] S53, based on the model prediction results, analyze the performance of each scheme in terms of nutrient utilization, crop yield, quality improvement, and stress resistance enhancement, and evaluate their advantages and disadvantages.

[0082] The following table is an example of a fertilization plan for polyglutamic acid and compound fertilizer:

[0083]

[0084]

[0085] Furthermore, step S6 specifically includes the following steps:

[0086] S61, Fertilization data collection: Fertilize crops by combining fertilization schemes. During the fertilization process, the intelligent fertilizer applicator records data such as fertilization time, fertilizer amount, and fertilization area. The data can be uploaded to the cloud database in real time for subsequent analysis and processing. During the growth of crops, detection equipment is used to regularly collect crop growth data, such as plant height, leaf area, and chlorophyll content. Crop growth data can reflect the growth status of crops and provide a basis for optimizing fertilization methods.

[0087] S62, Fertilization plan analysis: clean the collected fertilization data and crop growth data, remove outliers and duplicate data, and then integrate the cleaned data to form a complete data set; use charts, images, etc. to visualize the data set to more intuitively understand the relationship between fertilization and crop growth; use correlation analysis algorithms to find out the degree of correlation between fertilization data and crop growth data; use machine learning algorithms to train fertilization data and establish a prediction model, which can automatically adjust the fertilization plan based on historical fertilization data and crop growth data to achieve the purpose of increasing crop yields; according to test results and feedback information, continuously optimize software algorithms and combination plans.

[0088] Taking rice planting as an example, the combination of polyglutamic acid and compound fertilizer is analyzed:

[0089] Option 1: Physical mixing

[0090] The polyglutamic acid powder and compound fertilizer are physically mixed evenly in a certain proportion; an algorithm is used to predict the dissolution rate of the fertilizer, the nutrient release pattern and the impact on rice growth under this scheme; it is suitable for rice fields with good soil conditions and proper water management, and can improve nutrient utilization and rice yield.

[0091] Option 2: Chemical chelation

[0092] Chemically chelate polyglutamic acid with certain nutrients in compound fertilizers (such as trace elements such as zinc and iron) to form stable chelates; predict the stability and effectiveness of the chelates in soil and their effects on the absorption of trace elements by rice; apply them to soils lacking trace elements, and can increase the absorption and utilization rate of trace elements by rice, thereby improving rice quality.

[0093] Option 3: Encapsulation

[0094] The compound fertilizer particles are coated with polyglutamic acid solution to form a slow-release fertilizer; the regulatory effect of the coating treatment on the fertilizer release rate and the matching degree with the nutrient demand during the rice growth cycle are predicted; it is suitable for rice fields that require long-term fertilizer supply or a large amount of one-time fertilizer application, which can reduce the number of fertilization times and improve fertilizer utilization.

[0095] Through the above logic strategy and examples, the analytical method for combining polyglutamic acid and compound fertilizer provided by the present invention can systematically analyze and select the most suitable combination of polyglutamic acid and compound fertilizer for specific crops and soil conditions.

[0096] The present invention also provides a device, such as Figure 3 As shown, the device may be any terminal device including a mobile phone, a tablet computer, a personal digital assistant (PDA), a point of sales (POs), a car computer, etc., and a mobile phone is taken as an example:

Specifically, the input unit 1030 may include a touch panel 1031 and other input devices 1032. The touch panel 1031, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 1031 or near the touch panel 1031 using any suitable object or accessory such as a finger, stylus, etc.), and drive the corresponding connection device according to a pre-set program.
