Description

Technical Field

[0001] The invention belongs to the field of organic fertilizer preparation, and specifically relates to a moisture-retaining and drought-resistant biological organic fertilizer and a preparation method thereof. Background Art

[0002] Bio-organic fertilizer is a special type of fertilizer, made from a combination of specialized microorganisms and harmlessly treated, decomposed organic materials, primarily derived from animal and plant residues, such as livestock and poultry manure and crop straw. It combines the benefits of both microbial and organic fertilizers, containing both rich organic matter and functional microbial agents. Commonly used raw materials include agricultural waste, livestock and poultry manure, industrial waste, and domestic garbage. These materials require preliminary processing, such as crushing and mixing, to improve fermentation efficiency. The processed materials are then mixed evenly and then piled for fermentation.

[0003] Bio-organic fertilizers can significantly increase soil organic matter content and enhance the soil's fertility retention capacity. The humic acid produced by microbial decomposition of organic matter binds soil particles into aggregates, increasing soil porosity, air permeability, and water retention. Applying bio-organic fertilizers can significantly improve crop yield and quality, enhancing the taste of agricultural products. The beneficial microorganisms in bio-organic fertilizers can improve the rhizosphere microbiome of crops, inhibiting the growth of harmful bacteria and thereby increasing plant resistance to disease and pests. These microorganisms form dominant communities in the rhizosphere, reducing pathogenic infection. The production of bio-organic fertilizers utilizes agricultural waste, reduces environmental pollution, and improves the quality of agricultural products and farmers' incomes.

[0004] At present, the existing bio-organic fertilizer preparation technology has the following problems: First, the nutrient concentration of existing bio-organic fertilizers is low, the fertilizer effect is slow, and it cannot quickly and efficiently meet the crop's demand for a large number of elements; second, the existing bio-organic fertilizers do not have strong moisture retention and drought resistance capabilities. After application to the soil, they cannot effectively improve the pore structure of the soil and have weak water retention and drought resistance capabilities; third, the existing bio-organic fertilizers have weak adhesion and are easily washed away by water when encountering irrigation or rainfall, resulting in the inability to play a long-term role and causing waste of bio-organic fertilizers. Summary of the Invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a moisturizing and drought-resistant bio-organic fertilizer and a preparation method thereof. In order to solve the problems that the existing bio-organic fertilizer cannot quickly and efficiently meet the nutritional needs of crops, does not have the ability to retain moisture and resist drought, has weak adhesion, and cannot play a long-term role, the present invention uses a nutrient base, a moisturizing and drought-resistant component, and a long-acting stabilizing suspension for mixing.

[0015] Furthermore, in L1, the material-liquid ratio of the kelp to ultrapure water is 1.3:1 g / mL.

[0016] The present invention also proposes a method for preparing a moisture-retaining and drought-resistant bio-organic fertilizer, which specifically comprises the following steps: Step 1: Put the fruit charcoal powder, highland barley lees, and ultrapure water into a stirring tank with a power of 1.5-1.8 kW, stir at a temperature of 20-28 ° C, stir for 20 min, and stir at a speed of 300 r / min to obtain a long-lasting stabilizing suspension; Step 2: Add the nutrient base to the long-lasting stabilizing suspension prepared in step 1, stir at a temperature of 28° C., stir for 25 min, and stir at a speed of 500 r / min to obtain an organic fertilizer mixture; Step 3: Place the mixture of the moisturizing and drought-resistant component and the organic fertilizer prepared in step 2 into an ultrasonic agitator with a power of 1.8-2.5 kW, an ultrasonic frequency of 15 kHz, a stirring speed of 20,000 r / min, a stirring temperature of 25-30°C, and a stirring time of 10-15 min. After uniform dispersion, place it in a granulator with a power of 2.1-2.4 kW, a granulation temperature of 28-32°C, a granulation time of 30-45 min, and a granulation diameter of 1.2-1.6 mm to obtain a moisturizing and drought-resistant biological organic fertilizer.

[0017] Furthermore, in step 1, the material-liquid ratio of the fruit wood charcoal powder to ultrapure water is 1:2 g / mL.

[0018] The beneficial effects achieved by the present invention are as follows: The invention uses potatoes, taro and yam to boil and crush to obtain a starch matrix rich in organic substances such as starch and cellulose. After boiling, the organic substances contained can be more efficiently decomposed and utilized by microorganisms and converted into beneficial components such as humus, thereby increasing the organic matter content of the soil, improving the soil structure and increasing the aeration of the soil. The starch matrix contains a large number of hydroxyl groups, which react with the carboxyl groups on the carboxymethyl cellulose molecular chain under the action of epichlorohydrin to form a stable three-dimensional network structure. The obtained composite is more stable and has better adsorption performance and water retention capacity. The cattle bone meal, pig bone meal and chicken bone meal can quickly release nutrients. The nutrients and organic matter contained in the starch matrix can enhance the stress resistance of plants. Put it into the complex solution for full adsorption, and the obtained nutrient base can provide nutrients to the plants quickly and long-term, and continuously provide nutrient support for the plants; mix kelp, seaweed, and ultrapure water for pulping. Kelp and seaweed are rich in alginate, which has carboxyl and hydroxyl groups. The calcium ions in calcium chloride can form a bridge with the two carboxyl groups, thereby connecting the polysaccharide chains to form a gelled colloid component. The carboxyl group of tannic acid can also undergo esterification reaction with the hydroxyl groups in the alginate contained in kelp and seaweed to form a covalent bond, making the formed colloid network structure more stable. Under the joint action of calcium chloride and tannic acid, the polysaccharides in kelp and seaweed form a three-dimensional network structure through ionic crosslinking and covalent crosslinking. Atractylodes macrocephala, Solanum nigrum, Arisaema consanguineum After crushing the Chinese medicinal materials, such as perilla seeds, knotweed and horsetail, the obtained plant materials are rich in organic matter and multiple nutrients. After crushing, these components can be slowly released to provide comprehensive nutrient support for plant growth. The fine particles formed after the Chinese medicinal materials are crushed have a high specific surface area and can absorb and retain more water. The organic matter decomposes in the soil to form humus, which further increases the porosity and air permeability of the soil, reduces soil compaction, and enhances the water and fertilizer retention capacity of the soil. The plant components are placed in the colloid components, and the resulting moisturizing and drought-resistant components can maintain soil moisture for a long time, and cooperate with the nutrient base to enhance the plant's own resistance and enhance the plant's drought resistance. The fruit charcoal powder has an extremely high specific surface area and rich microporous structure. It can absorb a large amount of water and air to form a good water-retaining and breathable environment, reduce the loss of nutrients, and can exist in the soil for a long time, continuously playing the role of water and fertilizer retention. Highland barley lees contain a large amount of organic matter, protein, cellulose, sugar and a variety of trace elements that can promote the reproduction and metabolic activities of microorganisms in the soil. The long-term stabilizing suspension formed by fruit charcoal powder and highland barley lees can form a protective layer on the soil surface, maintain soil moisture for a long time, and reduce water evaporation on the soil surface. The moisturizing and drought-resistant components are mixed with the organic fertilizer mixture. The moisturizing and drought-resistant biological organic fertilizer prepared can provide nutrition to crops efficiently and quickly, has the ability to moisturize and resist drought, effectively improves soil structure, and can play a moisturizing and drought-resistant role for a long time.
