Description

Technical Field

[0001] The invention relates to the field of agricultural fertilizers, and in particular to a water-soluble fertilizer containing Chinese herbal medicine wood vinegar and a preparation method thereof. Background Art

[0002] There are large areas of saline-alkali land in Xinjiang, and the soil salinization phenomenon is serious, which has had many adverse effects on agricultural development. The high salt content in saline-alkali soil seriously interferes with the normal physiological activities of crops, resulting in the growth and development of crops such as grain and cotton being hindered, the planting area being limited, and it is difficult to increase the yield. For example, the high-salt environment will cause plant cells to lose water due to osmotic pressure imbalance, which in turn affects their growth, development and metabolic processes, resulting in grain and cotton production failing to meet market demand.

[0003] In order to increase crop yields, growers usually take measures to increase the amount of fertilizer used, but this approach has little effect in saline-alkali environments. Due to soil salinization, fertilizers cannot be effectively absorbed by crops, resulting in a large amount of fertilizer residue in the soil, which not only wastes resources but also causes serious environmental problems. Too much fertilizer is lost with irrigation water, which will cause a shortage of irrigation water. After flowing into water bodies, it will also cause eutrophication and other water environmental pollution. At the same time, long-term and large-scale use of fertilizers will destroy the soil structure, reduce soil permeability, cause soil compaction, further deteriorate soil quality, and form a vicious cycle.

[0004] In addition, agricultural production in Xinjiang is also constrained by other factors. The limitation of heat resources makes it impossible for many farmlands to achieve two crops a year, reducing the planting area and yield of summer crops. Variety selection and the adaptability of agricultural machinery also affect the yield and quality of crops to a certain extent. Some varieties have poor adaptability to saline-alkali land, and unsuitable agricultural machinery will reduce agricultural production efficiency. These factors together lead to insufficient agricultural product output, which in turn restricts the development of the breeding industry. Because the breeding industry relies on crops as a source of feed, the insufficient supply of agricultural products cannot meet its needs, resulting in unstable market supply and price fluctuations, which has a negative impact on the stability and development of the entire agricultural economy. Summary of the invention

[0005] In order to solve the above problems, especially to address the deficiencies in the prior art, the present invention provides a water-soluble fertilizer containing Chinese herbal medicine wood vinegar and a preparation method thereof, which can solve the above problems.

[0006] To achieve the above purpose, the present invention adopts the following technical means:

[0007] A water-soluble fertilizer containing Chinese herbal wood vinegar comprises the following raw materials in parts by mass: 3-4 parts of urea, 1-5 parts of potassium dihydrogen phosphate, and 45-55 parts of Chinese herbal wood vinegar.

[0008] A further solution of the present invention is to include the following raw materials in parts by weight: 3 parts of urea, 5 parts of potassium dihydrogen phosphate, and 45 parts of wood vinegar containing Chinese herbal medicine.

[0009] A further solution of the present invention is to include the following raw materials in parts by weight: 4 parts of urea, 4 parts of potassium dihydrogen phosphate, and 50 parts of wood vinegar containing Chinese herbal medicine.

[0010] A further solution of the present invention is to include the following raw materials in parts by weight: 4 parts of urea, 3 parts of potassium dihydrogen phosphate, and 55 parts of wood vinegar containing Chinese herbal medicine.

[0011] A method for preparing a water-soluble fertilizer containing Chinese herbal medicine wood vinegar comprises the following steps:

[0012] Step 1: Evenly mix the liquorice furfural residue water extract and EM bacterial powder, filter with a sieve, ferment at 25-28° C. for 36-48 hours to obtain a fermentation raw material, collect the upper liquid, and obtain a Chinese herbal medicine extract;

[0013] Step 2, stirring and mixing the fermentation raw material in step 1 with the licorice leaching wood vinegar waste liquid, adding water and EM bacterial powder to the mixed liquid, stirring and mixing evenly, and continuing to ferment at 28-32° C. for 15-20 days to obtain a fermentation material;

[0014] Step 3: filter and concentrate the fermentation material in step 2 to obtain a composite microbial fermentation liquid;

[0015] Step 4: Mix the Chinese herbal medicine extract in step 1 with the composite microbial fermentation liquid in step 3 to obtain Chinese herbal medicine-containing wood vinegar;

[0016] Step 5. Weigh the wood vinegar containing Chinese herbal medicine, urea and potassium dihydrogen phosphate in parts by mass, add urea and potassium dihydrogen phosphate to the wood vinegar containing Chinese herbal medicine in sequence, stir and mix evenly to obtain the water-soluble fertilizer containing the wood vinegar containing Chinese herbal medicine.

[0017] A further solution of the present invention is that in step 1, the mass ratio of the liquorice furfural residue water extract to the EM bacterial powder is 1000-2000:1.

[0018] A further solution of the present invention is that in step 1, the mesh size of the sieve is 100 to 150 meshes.

[0019] A further solution of the present invention is that in step 2, the mass ratio of the fermentation raw material to water is 1:8-10.

[0020] Licorice furfural residue water: Licorice furfural residue water is a by-product solution produced during the furfural extraction process of licorice.

[0021] In chemical production, furfural is usually produced by hydrolyzing raw materials containing lignocellulose (such as corn cobs, sugarcane bagasse, wood, etc.). For licorice, after the corresponding extraction process, some residues will remain. These residues contain a certain amount of water, which forms licorice furfural residue water.

[0022] It contains a variety of ingredients, which may include incompletely extracted active ingredients in licorice, such as glycyrrhizic acid, glycyrrhetinic acid, etc., as well as some residual chemicals, lignin, hemicellulose and other degradation products and other impurities during the furfural extraction process. In the preparation of the above-mentioned water-soluble fertilizer containing Chinese herbal medicine wood vinegar, licorice furfural residue water is used as the starting material, which provides a material basis for the subsequent fermentation using EM bacterial powder. Mixing it with EM bacterial powder for fermentation, under appropriate temperature, time and conditions, some of the substances in it can be converted into ingredients that are beneficial to the growth of crops, contributing part of the raw material basis for the final formation of water-soluble fertilizers with special effects. Its fermentation process will produce some new active substances and nutrients, such as amino acids, organic acids, etc. These products help to improve the soil environment, increase the nutrient supply of crops, and can improve soil fertility and promote plant growth.

[0023] EM bacterial powder: EM bacterial powder is a composite bacterial agent containing a variety of beneficial microorganisms, usually composed of photosynthetic bacteria, lactic acid bacteria, yeast, actinomycetes, acetic acid bacteria and other microbial flora.

[0024] These microorganisms play important roles in different aspects:

[0025] Photosynthetic bacteria: They can use light energy to separate hydrogen from hydrogen sulfide and hydrocarbons in the soil, turning harmful substances into harmless substances, and can synthesize sugars, amino acids, vitamins, nitrogen compounds, etc. with carbon dioxide, nitrogen and other substances, providing rich nutrients for plants. At the same time, photosynthetic bacteria can also promote the proliferation of other microorganisms and improve the microbial environment of the soil.

[0026] Lactic acid bacteria: They can produce a large amount of lactic acid, making the soil environment acidic, which is of positive significance for improving alkaline soil. At the same time, lactic acid can also inhibit the activities of harmful microorganisms, improve the water retention capacity of the soil, and promote plant growth. Lactic acid bacteria can decompose organic matter in the soil and provide nutrients for plants, such as decomposing complex organic matter into simple sugars, amino acids, etc., which are easy for plants to absorb.

[0027] Yeast: It can ferment secretions produced by plant roots and organic matter in the soil to produce active substances that promote cell division and provide the nutrients and energy required for plant growth. Yeast can also provide nutrients for the growth of other beneficial microorganisms, promote the balance and stability of microorganisms in the soil, and improve soil fertility.

[0028] Actinomycetes: They produce antibiotics and other antibacterial substances, inhibit pathogens in the soil, play a role in preventing diseases and protecting seedlings, and can effectively prevent plant diseases. They can decompose the difficult-to-decompose substances in animal and plant residues, provide nutrients that can be absorbed and utilized by plants, and improve the fertility and aeration of the soil.

[0029] Acetic acid bacteria: It can convert sugars into acetic acid, has a certain bactericidal effect, can inhibit the growth of harmful microorganisms, and create a favorable soil environment for plant growth. It can also synthesize a variety of vitamins and amino acids and other substances to promote plant growth and development.

[0030] EM bacterial powder plays a key role in the preparation of water-soluble fertilizer containing Chinese herbal wood vinegar. By mixing it with the aqueous extract of licorice furfural residue, the substances in the aqueous extract of licorice furfural residue can be fermented and converted into effective ingredients that are more easily absorbed and utilized by crops. EM bacterial powder participates in the reaction at different fermentation stages, and through the synergistic effect of different microorganisms, it converts the raw materials that were originally difficult to utilize into products containing rich nutrients and bioactive substances, such as various organic acids, amino acids, and active enzymes produced during the fermentation process. Ultimately, the prepared water-soluble fertilizer has many excellent characteristics such as increasing crop yields, improving soil structure, and inhibiting pests and diseases, providing comprehensive microbial support for the growth of crops and soil improvement.

[0031] EM powder is widely used in agriculture, environmental protection, breeding and other fields. Through the synergistic effect of the various beneficial microorganisms it contains, it can improve the ecological environment, promote the recycling of materials, and improve the productivity and stability of the system.

[0032] Licorice leaching wood vinegar waste liquid: Licorice leaching wood vinegar waste liquid is a waste liquid remaining after the effective ingredients are extracted from licorice, which contains wood vinegar components.

[0033] When licorice is processed, some extraction methods are used to extract the useful ingredients in licorice. This process will produce waste liquid, and wood vinegar is a liquid product produced during the pyrolysis or distillation of wood or other biomass.

[0034] Ingredients:

[0035] Wood vinegar usually contains organic acids, such as acetic acid, propionic acid, butyric acid, etc. These organic acids can adjust the pH of the soil, making it more suitable for the growth of crops. It is especially important for the improvement of saline-alkali land because its acidity can neutralize the alkalinity of the soil.

[0036] It also contains phenolic compounds, which have certain bactericidal and antibacterial effects, can help inhibit pathogens and harmful microorganisms in the soil, and reduce the occurrence of crop diseases and pests.

[0037] In addition, wood vinegar also contains alcohols, ketones, aldehydes and a variety of trace elements, which can provide rich nutrients for crops and promote their growth and development.

[0038] At the same time, some ingredients in wood vinegar may contain active substances that promote plant growth, such as stimulating the growth of plant roots and enhancing the plant's resistance to stress.

[0039] In the preparation process of the above-mentioned water-soluble fertilizer containing Chinese herbal medicine wood vinegar, the licorice leaching wood vinegar waste liquid participates in the fermentation process as a raw material. After it is mixed with the fermentation raw material and other substances, it will be further transformed and reacted under the action of microorganisms, providing rich nutrients and active ingredients for the final formation of water-soluble fertilizer containing Chinese herbal medicine wood vinegar. Through mixing and fermentation with other ingredients, the wood vinegar components contained therein can synergize with other substances, such as improving soil structure, activating nutrients in the soil, and improving the effectiveness of fertilizers. It can also work together with raw materials such as licorice furfural residue water extract and EM bacterial powder to give fertilizers more properties that are conducive to crop growth and soil improvement, and ultimately make the prepared water-soluble fertilizer products show good results in increasing crop yields, improving soil quality, and reducing the use of chemical fertilizers.

[0040] Licorice extraction wood vinegar waste liquid is a by-product with multiple potential values. It is rationally utilized in the preparation of water-soluble fertilizer containing Chinese herbal wood vinegar, achieving effective utilization of resources and comprehensive solution to many problems in agricultural development.

[0094] Experimental Results

[0095] 1. Crop yield:

[0096] A plurality of test fields were set up in saline-alkali land, one part of which was applied with the water-soluble fertilizer containing Chinese herbal medicine wood vinegar of the present invention, and the other part was applied with traditional fertilizer (such as urea) as a control. After one or more growth cycles of observation and data statistics, it was found that the crop yield of the test field using the water-soluble fertilizer of the present invention was significantly improved.

[0097] For grain and cotton crops, such as wheat, the average per-acre yield of wheat in the test field using the water-soluble fertilizer of the present invention can be increased by 20% compared with the control field using traditional chemical fertilizers. Specific data are: the per-acre yield of wheat in the control field using traditional chemical fertilizers is about 300 kilograms, while the per-acre yield of wheat in the test field using the water-soluble fertilizer of the present invention can reach 360 kilograms, and as the planting cycle is extended, the trend of yield improvement is more obvious.

[0098] As for cotton, the yield of cotton in the control field is limited by the saline-alkali soil conditions, and the yield may be low, with an average yield of 200 kg per mu. However, the yield of cotton in the test field using the water-soluble fertilizer of the present invention reaches 250 kg, and the yield increase reaches about 25%.

[0099] 2. Improvement of soil properties:

[0100] Soil pH:

[0101] Before applying the water-soluble fertilizer of the present invention, the pH value of the saline-alkali soil is usually 8.5-9.0. After a period of use, the soil is sampled and analyzed, and it is found that the pH value of the soil has decreased and gradually approached the neutral range, about 7.0-7.5, indicating that the acidic properties of the water-soluble fertilizer effectively neutralize the alkalinity of the soil, improve the pH value of the soil, and make it more suitable for the growth of crops.

[0102] Soil fertility index:

[0103] The main nutrient elements such as nitrogen, phosphorus and potassium in the soil were detected, and the effective nutrient content in the soil using the water-soluble fertilizer of the present invention increased. For example, the available nitrogen content in the soil increased from 50 mg / kg before use to 80 mg / kg, the available phosphorus increased from 10 mg / kg to 18 mg / kg, and the available potassium increased from 80 mg / kg to 120 mg / kg, indicating that the water-soluble fertilizer can activate the nitrogen, phosphorus and potassium elements remaining in the soil, so that they can be reused by crops, thereby improving soil fertility.

[0104] The organic matter content of the soil also increased, from 1.5% before use to 2.5%, which shows that the rich organic matter in the water-soluble fertilizer can replenish organic matter in the soil and improve the soil fertility.

[0105] Soil physical properties:

[0106] Through soil structure analysis, after using the water-soluble fertilizer of the present invention, the soil aggregate structure is improved, the soil porosity is increased, and the soil permeability is enhanced. Specifically, the soil bulk density is reduced from 1.4g / cm before use to 3 Down to 1.2g / cm 3 , which is beneficial to the respiration and growth of plant roots and promotes the absorption of nutrients and water by the roots.

[0107] 3. Pest and disease control:

[0108] Statistics were taken on the occurrence of pests and diseases in the test field using the water-soluble fertilizer of the present invention and the control field, and it was found that the occurrence rate of pests and diseases in the test field using the water-soluble fertilizer of the present invention was significantly reduced.

[0109] For common underground pests and diseases, such as nematodes and white grubs, the incidence rate in the control field may be as high as 30%, while the incidence rate in the test field using the water-soluble fertilizer of the present invention is only 10%, which shows that the Chinese herbal medicine ingredients in the water-soluble fertilizer have a preventive and inhibitory effect on the growth of underground pests and diseases in the soil, reduce the harm of pests and diseases to crops, and reduce the yield loss caused by pests and diseases.

[0110] IV. Fertilizer application and resource utilization:

[0111] After using the water-soluble fertilizer of the present invention, the amount of chemical fertilizer applied by the growers is gradually reduced. By recording and counting the amount of fertilizer applied, it is found that a large amount of traditional chemical fertilizers, such as 50 kg of urea per mu, are required to be applied during the planting process. After using the water-soluble fertilizer of the present invention, the amount of chemical fertilizers such as urea can be reduced. Depending on the crop, the amount can be reduced by about 10-20 kg, while still ensuring or increasing the crop yield. This reflects that the water-soluble fertilizer of the present invention improves the utilization rate of water and fertilizer and reduces the waste of chemical fertilizers.

[0112] V. Impact on the environment:

[0113] Irrigation water quality:

[0114] The water quality of the surrounding irrigation water is monitored. In areas where traditional chemical fertilizers are used, the total nitrogen, total phosphorus and other indicators in the water body may exceed the standard due to the large amount of fertilizer loss. In areas where the water-soluble fertilizer of the present invention is used, the total nitrogen and total phosphorus contents in the water body are relatively low, which meets the irrigation water quality standards. This shows that the water-soluble fertilizer reduces the irrigation water pollution caused by the loss of chemical fertilizers, and alleviates the problems of irrigation water shortage and water environment pollution.

[0115] 6. Impact on the aquaculture industry:

[0116] Due to the increase in crop yields, more feed sources are provided for the breeding industry accordingly. For example, after using the water-soluble fertilizer of the present invention, the increase in grain and cotton yields can provide more feed raw materials for the breeding industry, thereby promoting the development of the breeding industry.

[0117] For example, the livestock inventory that was originally limited due to insufficient crop yields may increase from 5 heads / mu to 8 heads / mu, and the growth condition of the livestock is better, and the meat quality and yield may also be improved. This is because the quality of the crops grown using the water-soluble fertilizer of the present invention as feed may be improved, providing a better material basis for the breeding industry.

[0118] These experimental results show that the water-soluble fertilizer containing Chinese herbal wood vinegar of the present invention has significant effects in increasing crop yields, improving soil quality, preventing and controlling pests and diseases, improving resource utilization and promoting ecological environment improvement, demonstrating its great potential and advantages in solving the many problems faced by the development of saline-alkali land agriculture in Xinjiang.

[0119] The examples given in the present invention are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here, and the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
