Description

Technical Field

[0001] The invention belongs to the technical field of biological organic fertilizers, and in particular relates to an organic fertilizer for disease resistance of peanuts and a preparation method thereof. Background Art

[0002] Peanut is an important oil crop with high nutritional value. It is known as "plant meat" and has an oil content of up to 50%. Peanut not only provides a source of edible oil and protein, but also has an important impact on the agricultural economy and farmers' income. However, peanuts are susceptible to a variety of diseases during the planting process, which directly affect the yield and quality of peanuts. For example, peanut root diseases mainly include root rot, stem rot, bacterial wilt and white rot, which seriously affect the growth and yield of peanuts. Peanut leaf diseases (including black spot, brown spot, net spot, etc.) will cause leaves to fall off prematurely, affecting photosynthesis and thus reducing peanut yields. The affected fields generally reduce production by 10% to 20%, and in severe cases, the reduction can reach more than 40%. In addition, diseases will also cause the quality of peanut fruits to decline, affecting market sales.

[0003] In order to effectively control peanut diseases, people often spray pesticides for prevention and control when necessary, such as using oxazolidinone, pyraclostrobin and other chemical sprays to prevent leaf diseases. However, studies have shown that long-term application of chemical agents may lead to changes in certain environmental indicators in the soil, such as increased content of available phosphorus, available manganese, available zinc, and soil heavy metals Hg and Cu, and also greatly disturb the soil pH, thereby reducing soil quality. Bio-organic fertilizer is an efficient and environmentally friendly fertilizer that can reduce the use of chemical fertilizers and pesticides in agricultural production, thereby reducing environmental pollution. However, most of the organic fertilizers used in peanut planting are broad-spectrum organic fertilizers, and a large number of elements can basically meet the growth needs of peanuts, but lack components for diseases during peanut planting, thus affecting peanut yield and commodity value.

[0004] To this end, the present invention provides an organic fertilizer for disease resistance of peanut and a preparation method thereof. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides an organic fertilizer for disease resistance of peanut and a preparation method thereof.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] One of the technical solutions of the present invention:

[0008] An organic fertilizer for peanut disease resistance, comprising, by weight, 2-25 parts of peanut seedlings, 3-8 parts of a Chinese medicine composition, 10-50 parts of fermented materials, 0.5-0.8 parts of a microbial fermentation agent, 5-10 parts of humic acid and 1-3 parts of brown sugar;

[0009] The traditional Chinese medicine composition comprises lavender, Jerusalem artichoke, rhizoma dioscoreae and earthworm castings.

[0010] The disease-resistant organic fertilizer for peanuts of the present invention can not only promote the growth of peanuts and improve the soil environment, but also improve the disease resistance of peanuts. The lavender, Jerusalem artichoke, Chinese magnolia vine and earthworm castings in the Chinese medicine composition contain multiple biologically active ingredients, which can enhance the natural disease resistance of peanuts, kill field pests and improve the lodging resistance of peanuts. The microbial fermentation agent can promote the release and absorption of the effective ingredients of the Chinese medicine composition in the soil, improve its biological activity, and thus improve the disease resistance. Brown sugar, as a carbon source in the organic fertilizer, can significantly improve the photosynthesis of leaves, make the leaves thicker, and improve the disease resistance of peanuts. The fermentation material provides rich organic matter and nutrients, and provides an ideal environment for the growth and reproduction of the microbial fermentation agent. At the same time, the microorganisms Activities can increase the organic acid in the soil, promote mineral weathering and nutrient release, and improve the effectiveness of mineral nutrients in the soil. Healthy soil can resist the invasion of pathogens and pests and reduce the chance of peanut disease. Humic acid can improve the soil's ability to retain water and fertilizer, increase the number of large soil aggregates, and enhance aggregate stability. Microbial fermentation agents can further decompose humic acid, increase the number of beneficial microorganisms in the soil, and improve the biological activity of the soil and the buffering properties of the soil. The roots and stems of peanut vines contain endogenous strains, which colonize in the peanut plants with the application of fertilizers, especially in the root area of ​​the peanut plants, where they can survive and play a role, and have a positive effect on the growth of peanuts. In terms of adjusting the soil microbial composition and improving enzyme activity, it has a significant ability to solve the problem of continuous cropping. Therefore, the present invention controls the types and amounts of each raw material in the organic fertilizer for disease resistance of peanuts, which can not only improve the soil and promote the release of nutrients fixed by the soil, improve the physical and chemical properties and biological activity of the soil, but also significantly increase the diversity and richness of rhizosphere bacteria in peanuts, increase the relative abundance of rhizosphere growth-promoting bacteria, and reduce the relative abundance of pathogenic bacteria, thereby optimizing the soil microecological environment and improving the disease resistance of peanuts.

[0011] Furthermore, the Chinese medicine composition comprises lavender, Jerusalem artichoke, Polygonum multiflorum and earthworm castings in a mass ratio of 8:2:1:(7-9).

[0012] Furthermore, the microbial fermentation agent includes Bacillus thuringiensis, Bacillus amyloliquefaciens and Bacillus subtilis.

[0013] Furthermore, the total live bacteria content in the microbial fermentation agent is 50-100 billion cfu / g.

[0014] Furthermore, the humic acid is activated humic acid.

[0015] Furthermore, the activated humic acid is prepared by physically activating, chemically activating or biologically activating humic acid.

[0016] Furthermore, the fermented material includes poultry and livestock manure, cassava residue, straw and tea seed cake.

[0017] Furthermore, the fermentation material includes livestock manure, cassava residue, straw and tea seed cake in a mass ratio of (3-6):4:8:3.

[0018] The second technical solution of the present invention:

[0019] A method for preparing the disease-resistant organic fertilizer for peanuts comprises the following steps:

[0020] Weigh each raw material by weight, mix the Chinese medicine composition, fermentation material, humic acid and brown sugar evenly, then add microbial fermentation agent and water for mixed fermentation, add crushed peanut vineyards to the obtained fermentation liquid, vacuum dry and crush, and obtain the peanut disease-resistant organic fertilizer.

[0021] Through mixed fermentation, the nutrients and active substances in the Chinese medicine composition, fermentation material, humic acid and brown sugar are decomposed and transformed by microorganisms to form a fermentation liquid rich in various beneficial ingredients. Adding the crushed peanut vines to the fermentation liquid can further improve the nutritional value of the organic fertilizer and the soil improvement effect. The moisture content in the organic fertilizer can be reduced by vacuum drying to prevent excessive growth of microorganisms and loss of nutrients while maintaining the active ingredients of the organic fertilizer. The crushed organic fertilizer particles are smaller and easier to apply and absorb by peanuts, thereby improving the disease resistance of peanuts and promoting the growth of peanuts, while improving the soil environment and increasing the fertility and biological activity of the soil.

[0022] Furthermore, the amount of water added is 20%-30% of the total weight of the Chinese medicine composition, fermentation material, humic acid and brown sugar.

[0023] Furthermore, the temperature of the mixed fermentation is 30-32°C and the time is 2-5 days.

[0024] Furthermore, the vacuum drying temperature is 30-35°C, and the particles are crushed to 0.4-0.6 mm.

[0025] Compared with the prior art, the present invention has the following advantages and technical effects:

[0026] (1) The disease-resistant organic fertilizer for peanuts of the present invention can effectively improve the soil, promote the growth and development of peanuts, enhance the stress resistance of peanuts, improve the disease resistance of peanuts, and greatly improve the quality of peanuts while increasing the fertilizer efficiency.

[0027] (2) The peanut disease-resistant organic fertilizer of the present invention has a simple production and processing technology, a wide source of raw materials, and the raw materials are easily available. While waste can be utilized, a peanut disease-resistant special fertilizer with more diverse functions can be prepared, which has a high promotion value. DETAILED DESCRIPTION

[0113] Planting experiment

[0114] The experiment was conducted on a continuous cropping field planted with peanuts for more than 3 years. The control group used ordinary compound fertilizer (Luxi Chemical Industry-sulfur-based general compound fertilizer 12-18-15) for fertilization as a base fertilizer, and the fertilizer application amount was 60 kg / mu. The other groups used organic fertilizers prepared in Examples 1 to 9 and Comparative Examples 1 to 6 for fertilization, and the fertilizer application amount was 200 kg / mu. The other field management was the same.

[0115] The statistical results of the emergence rate and pests and diseases of each group of peanuts during the growth period are shown in Table 1.

[0116] Table 1 Statistical results of emergence rate and pests and diseases of each group of peanuts during growth period

[0117] deal with Seedling rate / % Seedling death rate / % Root rot / % Occurrence of underground pests Control group 93.8 5.3 18.7 Medium to heavy Example 1 99.9 0.4 5.3 Almost no Example 2 99.8 0.5 6.7 Almost no Example 3 99.4 0.9 5.8 Almost no Example 4 99.3 0.8 6.6 Almost no Example 5 99.5 0.7 5.9 light Example 6 99.8 0.6 6.1 Almost no Example 7 99.7 0.6 6.3 Almost no Example 8 99.8 0.7 5.5 light Example 9 99.4 0.9 6.4 Almost no Comparative Example 1 96.4 2.3 10.3 middle Comparative Example 2 95.8 2.7 9.4 middle Comparative Example 3 94.3 1.9 10.2 middle Comparative Example 4 95.5 2.4 11.4 light Comparative Example 5 94.7 1.9 9.7 middle Comparative Example 6 95.1 2.2 10.8 middle

[0118] According to the results in Table 1, it can be seen that the peanuts in Examples 1-9 have a high emergence rate, less dead seedlings, less root rot and less insect pests, which shows that the organic fertilizer of the present invention provides more suitable nutrition for the growth of peanuts and also has more significant disease and insect pest resistance. Compared with Example 1, in the case where peanut vines, Chinese medicine composition and humic acid are not added, the disease resistance of peanuts is significantly reduced in Comparative Examples 1-3, which shows that peanut vines, Chinese medicine composition and humic acid are indispensable in the organic fertilizer for peanut disease resistance. In Comparative Example 4, when the dosage of each raw material is changed, the emergence rate of peanuts is not as good as that of the embodiment, and the root rot and disease and insect pest situation are more serious, which shows that only within the dosage range of the present invention can the growth of peanut plants reach a better state. The microbial fermentation agent of Comparative Example 5 is only Bacillus thuringiensis, and no other agents are used. The results show that the emergence rate of peanuts is lower than that of the embodiment, and the disease and insect pest resistance is much lower than that of the embodiment, which shows that only using Bacillus thuringiensis can not make peanuts achieve good disease resistance. In Comparative Example 6, the preparation method was changed, and the peanut vines also participated in the mixed fermentation process. It may be that during the mixed fermentation process, the colonization effect of the endophytic strains in the roots and stems of the peanut vines in the peanut plants was reduced, and thus it did not play a positive role in promoting the growth of peanuts.

[0119] The statistical results of peanut yield in each group are shown in Table 2 (average value).
