Description

Technical Field

[0001] The invention relates to the technical field of fertilizers, and in particular to an organic-inorganic fusion peanut fertilizer and a preparation method thereof. Background Art

[0002] The selection and use of peanut fertilizers are crucial to the growth and yield of peanuts. They can provide peanuts with sufficient nutrients such as nitrogen, phosphorus, and potassium, promote the growth and development of peanut plants, increase the yield and quality of peanuts, improve soil structure, increase soil fertility and water retention capacity, promote the reproduction and activity of soil microorganisms, enhance the disease resistance of peanut plants, and reduce the occurrence of diseases and pests. Therefore, the development of an organic-inorganic fusion peanut fertilizer is of great significance.

[0003] Peanut fertilizers in the related art include urea, ammonium nitrate, superphosphate, diammonium phosphate, potassium sulfate, and potassium chloride; among them, urea and ammonium nitrate provide nitrogen elements for peanut fertilizers, which can meet the needs of peanuts for nitrogen forms in different growth periods, promote the vigorous growth of peanut branches and leaves, increase the leaf area, improve the photosynthesis efficiency, and lay the foundation for subsequent flowering and fruiting; superphosphate and diammonium phosphate provide phosphorus elements for peanut fertilizers, which play a key role in the development of peanut roots, promote the growth and branching of peanut roots, make the root system stronger, enhance the ability of peanuts to absorb water and nutrients in the soil, and improve the stress resistance of peanuts, such as enhancing the adaptability of peanuts to adverse environments such as drought and low temperature, and contribute to the metabolism and conversion of energy in peanut plants; potassium sulfate and potassium chloride provide potassium elements for peanut fertilizers, which can regulate the osmotic pressure of peanut plants, promote the absorption and transportation of water by peanuts, help enhance the lodging resistance of peanuts, improve the photosynthesis efficiency of peanut leaves, and promote the transportation and accumulation of photosynthetic products to pods, thereby improving the yield and quality of peanuts.

[0004] However, the peanut fertilizer production process in the above-mentioned related technology still has some shortcomings, such as incomplete nutrition. The peanut fertilizer in the related technology focuses on providing one or several major nutrients, such as nitrogen, phosphorus, potassium, etc., but ignores the supplement of other trace elements. Although this fertilizer can meet the basic needs of peanut growth, it may not provide comprehensive and balanced nutritional support, thereby affecting the overall growth and development of peanuts; the soil improvement effect is poor. Long-term use of related technology fertilizers will lead to problems such as soil structure destruction, soil compaction, and decreased fertility, which will change the cation exchange capacity in the soil, and the agglomeration between soil particles will deteriorate, resulting in soil compaction. Soil compaction will affect the air permeability and water permeability of the soil. The growth of peanut roots in compacted soil is hindered, making it difficult to extend and expand, which is not conducive to the absorption of nutrients and water by peanuts; the environmental impact is large. The nutrients in the related technology fertilizers are easily lost to the environment, causing water pollution and soil pollution. Summary of the invention

[0005] In view of the problems that existing peanut fertilizers have incomplete nutrition and poor soil improvement effect, the present invention provides an organic-inorganic fusion peanut fertilizer and a preparation method thereof to solve the above problems.

[0006] In a first aspect, the present invention provides an organic-inorganic fusion peanut fertilizer, comprising the following raw materials in parts by weight: 30-40 parts of fresh chicken manure, 6-10 parts of straw, 15-25 parts of soybean meal, 15-45 parts of urea, 15-45 parts of diammonium phosphate, 10-20 parts of potassium sulfate, 16-20 parts of superphosphate, 6-10 parts of zinc ammonium phosphate, 3-5 parts of manganese ammonium phosphate, 3-10 parts of magnesium ammonium phosphate, 5-10 parts of copper sulfate, and 3-5 parts of borax.

[0007] In a second aspect, the present invention provides a method for preparing an organic-inorganic fusion peanut fertilizer, comprising the following steps: (1) Collect fresh chicken manure, add straw shreds, adjust the moisture content, and then pile and ferment the resulting product until the color of the chicken manure changes to dark brown, has no odor, and has a loose texture, thereby obtaining decomposed chicken manure; (2) adding soybean meal to the decomposed chicken manure obtained in step (1), stirring at a speed of 300-600 r / min for 20-30 min, to obtain an organic composition; (3) mixing urea, diammonium phosphate, potassium sulfate, superphosphate, zinc ammonium phosphate, manganese ammonium phosphate, magnesium ammonium phosphate, copper sulfate and borax in a blender, stirring for 10 to 20 minutes at a stirring speed of 500 to 800 r / min to obtain an inorganic composition; (4) Add the organic composition obtained in step (2) and the inorganic composition obtained in step (3) into a blender and mix them evenly. Stir at a speed of 300-600 r / min for 20-30 min. Take out the mixture and put it into a drying device to obtain an organic-inorganic fusion peanut fertilizer.

[0008] Furthermore, in step (1), the moisture content is adjusted to 50% to 60%.

[0009] Furthermore, during the pile fermentation in step (1), the pile is turned over every 3 to 5 days, and the fermentation time is 30 to 45 days.

[0010] Furthermore, in step (4), the mixture is dried at 60-80° C. to a moisture content of 10%.

[0011] Furthermore, the soybean meal is obtained by crushing the soybean meal into fine soybean meal powder of 100-200 mesh.

[0012] Furthermore, the straw chips are prepared as follows: the selected straw is cut into small segments with a length of 2 cm using a straw chopper.

[0013] Furthermore, the straw is one of wheat straw, corn straw or rice.

[0014] The beneficial effects of the present invention are: The organic-inorganic fusion peanut fertilizer provided by the present invention combines the advantages of organic fertilizer and inorganic fertilizer, contains both rapidly released inorganic nutrients and slowly released organic nutrients, and may also add a variety of trace elements, which can provide more comprehensive and balanced nutritional support to meet the needs of the entire growth cycle of peanuts. The fertilizer of the present invention contains a large amount of organic matter, which can improve the soil structure, enhance the air permeability and water and fertilizer retention capacity of the soil, and its inorganic nutrients can reduce the loss and waste of nutrients and improve the fertilizer utilization rate under the regulation of organic fertilizer, thereby further improving the soil ecological environment. The fertilizer of the present invention contains a large amount of organic matter and microorganisms, which can reduce the use of chemical fertilizers and reduce the risk of nutrient loss. Through organic-inorganic fusion, it can also reduce the accumulation of harmful substances in the soil and reduce the risk of soil-borne diseases. DETAILED DESCRIPTION

[0026] Test Case The organic-inorganic fusion peanut fertilizer prepared in each embodiment was selected for testing. The test object was 100 mu of peanut fields, with 10 mu in each group. The tested peanut fields were applied with the organic-inorganic fusion peanut fertilizer prepared in each embodiment to keep the peanuts growing healthily. Before sowing peanuts, 75 kg of the organic-inorganic fusion peanut fertilizer prepared in each embodiment was applied per mu, and no other fertilizer was applied. The peanut emergence rate and soil fertility after fertilization were tested, and the specific testing steps were as follows: Peanut germination rate: First, samples were taken from the peanut fields before and after fertilization, and the peanut germination rate was calculated based on the ratio of the difference between the total number of sowings before fertilization and the total number of germinations after fertilization, which was used to characterize the improvement effect of the organic-inorganic fusion peanut fertilizer on the peanut field ecology. The test results and evaluation criteria are as follows: Peanut germination rate <50% is considered low; If the peanut germination rate is 50%<and 80%, it is considered as a normal peanut germination rate; A peanut germination rate of 80% or less is considered a high peanut germination rate.

[0027] Soil fertility growth rate: First, samples were taken from the peanut fields before and after fertilization, and the organic matter content in the soil was determined by the potassium dichromate volumetric method. The soil fertility growth rate was calculated based on the ratio of the difference between the organic matter content before and after fertilization to characterize the improvement effect of the organic-inorganic fusion peanut fertilizer on the peanut field ecology. The test results and evaluation criteria are as follows: The soil fertility growth rate is less than 20%, which is considered as low soil fertility growth rate; 20%<soil fertility growth rate<50%, which is considered as normal soil fertility growth rate; A soil fertility growth rate of 50% or less is considered to be high.

[0028] It should be specifically explained that the above organic-inorganic fusion peanut fertilizer is an organic-inorganic fusion peanut fertilizer prepared in a normal preparation process.

[0029] The organic-inorganic fusion peanut fertilizers in Examples 1 to 10 were used to test the peanut emergence rate and soil fertility growth rate according to the above measurement steps and measurement standards. The average values ​​of the test results are shown in Table 1.

[0030] Table 1-Performance test results of organic-inorganic fusion peanut fertilizers in Examples 1 to 10

[0031] As can be seen from Table 1, the organic-inorganic fusion peanut fertilizers prepared in Examples 1 to 5 all have a good effect of improving the ecology of peanut fields, and can provide comprehensive and balanced nutrients, improve soil structure, increase nutrient utilization, and promote peanut growth and development; they contain both nitrogen, phosphorus, potassium and other macroelements required for crop growth, and are rich in organic matter, trace elements and microorganisms, etc. This fertilizer can fully and balancedly meet the nutrient requirements of peanuts at different growth stages, promote the robust growth of peanut plants, thereby achieving the purpose of increasing peanut yield and improving soil environment; the peanut emergence rate before and after fertilization is 81.2% to 85.2%, which is considered to be a high peanut emergence rate, and the soil fertility growth rate is 50.6% to 53.0%, which is considered to be a high soil fertility growth rate.

[0032] The organic-inorganic fusion peanut fertilizers prepared in Examples 6-10 all have a good effect of improving the ecology of peanut fields, and can provide comprehensive and balanced nutrients, improve soil structure, increase nutrient utilization, and promote peanut growth and development; they contain both nitrogen, phosphorus, potassium and other macroelements required for crop growth, and are rich in organic matter, trace elements and microorganisms, etc. This fertilizer can fully and balancedly meet the nutrient requirements of peanuts at different growth stages, promote the robust growth of peanut plants, thereby achieving the purpose of increasing peanut yield and improving soil environment; the peanut emergence rate before and after fertilization is 82.1%~83.9%, which is considered to be a high peanut emergence rate, and the soil fertility growth rate is 50.9%~51.7%, which is considered to be a high soil fertility growth rate.

[0033] When the dosage of organic-inorganic fusion peanut fertilizer is certain, the improvement effect on the peanut field ecology can be increased by adjusting the preparation conditions. It is not difficult to see from the performance of Example 1 and Example 6 to 10 in Table 1 above that increasing the water content of the decomposed chicken manure, reducing the frequency of turning the compost during fermentation, extending the fermentation time, increasing the stirring speed and stirring time, and increasing the drying time can effectively improve the quality of the organic-inorganic fusion peanut fertilizer. The reason for this is that increasing the water content of decomposed chicken manure can provide a more suitable environment for the growth and reproduction of microorganisms. They decompose the organic matter in the chicken manure into something that is easier to be absorbed and utilized by peanuts. A higher water content can also make the texture of the decomposed chicken manure more uniform and delicate. , so that when it is mixed with other fertilizer ingredients, it can be better integrated together, thereby improving the overall uniformity of the fertilizer; reducing the frequency of turning the pile can keep the chicken manure at a relatively stable temperature, humidity and oxygen content during the fermentation process so that it can gradually form an ecosystem suitable for the growth of microorganisms; extending the fermentation time can make the organic matter in the chicken manure more fully decomposed, convert unstable organic nutrients into stable forms, and reduce nutrient loss and volatilization; increasing the stirring speed and stirring time can make the various components in the organic-inorganic fusion peanut fertilizer more evenly mixed together, thereby promoting chemical reactions; increasing the drying time will make some unstable components in the fertilizer gradually become stable during the drying process.

[0034] When the dosage of organic-inorganic fusion peanut fertilizer is certain, the improvement effect on the peanut field ecology can be increased by adjusting the proportion of each component. Combined with the data in the above table, it is not difficult to see that the increase of fresh chicken manure, soybean meal, urea and diammonium phosphate can enhance the promotion effect on peanut germination, and it will tend to saturation after reaching a certain amount, while the remaining components have general effect on performance.

[0035] Although the present invention has been described in detail by way of preferred embodiments, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, a person of ordinary skill in the art may make various equivalent modifications or substitutions to the embodiments of the present invention, and such modifications or substitutions shall be within the scope of the present invention. Any person of ordinary skill in the art may easily conceive of changes or substitutions within the technical scope disclosed by the present invention, and such changes or substitutions shall be within the scope of protection of the present invention.
