Description

Technical Field

[0001] The invention relates to the technical field of fertilizer preparation, in particular to a method for preparing a composite biological fertilizer mainly composed of aquatic products. Background Art

[0002] Aquatic products are a general term for aquatic products from marine and freshwater fisheries, including shrimp, crab, and fish viscera, bones, and shells, which are rich in organic and inorganic substances.

[0003] The viscera, bones and shells in aquatic products are often treated as waste and have low utilization rates. Summary of the invention

[0004] The object of the present invention is to provide a method for preparing a composite biofertilizer mainly composed of aquatic products, so as to solve the problem that the viscera, bones and shells in aquatic products are often treated as waste materials and have low utilization rates as mentioned in the above background technology. To achieve the above object, the present invention provides the following technical scheme: a method for preparing a composite biofertilizer mainly composed of aquatic products, comprising a composite biofertilizer, wherein the composite biofertilizer comprises 50% by weight of aquatic products, 4% by weight of crustacean shells, 15% by weight of organic matter, 1% by weight of EM bacteria, 5% by weight of molasses, 5% by weight of humic acid and 20% by weight of water.

[0005] The aquatic products include one or more of fish bones, fish heads, fish scales, fish meat, fish fins, fish intestines, fish maws, fish gills, etc., which are used to provide nitrogen, phosphorus, potassium and protein; the crustacean shells include one or more of shrimp shells and crab shells, which are used to provide calcium, chitin and trace elements; the organic matter includes one or more of leaves or fruit peels, which are used to supplement the proportion of nitrogen and provide minerals such as magnesium and iron.

[0006] The steps include:

[0007] S1: Rinse the aquatic products, crustacean shells and organic matter with clean water to remove grease and impurities on the surface, and then crush or air-dry and grind the aquatic products, crustacean shells and organic matter to obtain a mixed powder;

[0008] S2: The mixed powder obtained in S1 is fully mixed by a mixer or manually;

[0009] S3: adding EM bacteria and molasses to the process of S2;

[0010] S4: Add water in the S3 process to keep the humidity of the material between 50% and 60%;

[0011] S5: The material obtained in S4 is piled in a fermentation tank and covered with plastic film to maintain suitable temperature and humidity. The temperature is controlled at 30-35°C. The pile is turned over every 3-5 days to ensure that the material is fully exposed to air and accelerate the fermentation process. During the fermentation process, pay attention to the changes in the color and smell of the material to ensure that the fermentation is proceeding normally.

[0012] S6: After 2 to 3 months of fermentation, the material will turn black or dark brown, emit a strong humus smell, and obtain compound bio-fertilizer.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the present invention, the composite bio-fertilizer is rich in macroelements such as nitrogen, phosphorus, potassium and nutrients such as protein. The nitrogen element contributes to the growth of leaves, making the plants flourish and accumulating sufficient photosynthetic products for flowering; the phosphorus element is essential for the differentiation of flower buds, and can promote the formation and development of flower buds and increase the number of flowers; the potassium element can enhance the stress resistance of plants, so that the plants can better cope with environmental changes during flowering.

[0015] In the present invention, trace elements such as calcium provided by shrimp shells and crab shells are helpful for the formation and stabilization of plant cell walls, thereby ensuring the integrity of flower structures. Chitin is an important component in raw materials such as shrimp shells and crab shells. When chitin is added to the soil, it will decompose and produce chitosan under the action of microorganisms. Chitosan can induce plants to produce defense responses and activate the plant's own immune system, thereby inhibiting the growth and infection of pathogens.

[0016] In the present invention, minerals such as magnesium and iron supplemented by leaves or peels participate in physiological processes such as photosynthesis and chlorophyll synthesis of plants, ensuring that the plants can carry out photosynthesis normally and providing sufficient energy for flowering.

[0017] In the present invention, humic acid can adjust the soil pH and create a suitable soil pH environment for flowering plants. Many flowering plants have certain requirements for soil pH. For example, azaleas like acidic soil, and the soil adjusted by humic acid can better meet the needs of such plants. At the same time, humic acid can improve the soil structure, increase soil aeration and water permeability, which is beneficial to the growth and respiration of the roots of flowering plants. Good soil structure can enable the roots to better absorb various nutrients in fertilizers, thereby providing sufficient nutrient support for the opening of flowers.

[0018] In the present invention, EM bacteria release some plant growth hormones and bioactive substances in the process of decomposing organic matter. These substances can stimulate the growth and development of flowering plants, such as promoting root growth, increasing the thickness of stems, etc. Moreover, the activity of microorganisms can convert organic nutrients in fertilizers into forms that are more easily absorbed by plants, improve the utilization rate of fertilizers, and enable flowering plants to absorb key nutrients such as phosphorus more efficiently, thereby promoting flower bud differentiation and flowering.

[0019] In the present invention, molasses provides a carbon source for microorganisms during the fermentation process, and after being applied to the soil, it can improve the activity of soil microorganisms. These microorganisms can form a symbiotic relationship with plant roots, and enhance the resistance of plants to adversities such as pests and diseases, drought, and high temperature. For flowering plants, it is very important to maintain a good health state during the flowering period. Enhancing stress resistance can ensure that flowers open smoothly and reduce the phenomenon of falling flowers and buds due to adversity. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 It is a schematic diagram of the process structure of the present invention. DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1: The composite biological fertilizer and wood ash in a ratio of 3:1 are suitable for Solanaceae vegetables, such as tomatoes and eggplants. These vegetables require a large amount of potassium to promote fruit development and enhance the stress resistance of the plants during their growth. They are suitable for acidic soils. The composite biological fertilizer is slightly acidic after fermentation, and wood ash is an alkaline fertilizer. The mixture of the two can adjust the pH of the soil to make the soil close to neutral. At the same time, the potassium in the wood ash can supplement the relatively insufficient potassium content in the fish intestine fertilizer, providing comprehensive nutrition for Solanaceae vegetables.

[0023] Embodiment 2: The composite biological fertilizer and solid chicken manure in a ratio of 1:2 are suitable for leafy plants, such as spinach, lettuce, etc. Leafy plants grow rapidly and have a high demand for nitrogen fertilizer. Fish intestine fertilizer and chicken manure are rich in nitrogen, which can meet the growth needs of leafy plants and are suitable for soils with medium or slightly poor fertility. Chicken manure is an organic fertilizer with comprehensive nutrition and strong fertility. Mixing it with fish intestine fertilizer can quickly improve soil fertility, provide sufficient nutrients for leafy plants, and improve the nutrient structure of the soil.

[0024] Embodiment 3: The composite biofertilizer and cow dung in a ratio of 1:3 is suitable for fruit trees, such as apple trees, pear trees, etc. Fruit trees have a long growth cycle and require a continuous and stable supply of nutrients. This combination can provide long-term organic fertilizer for fruit trees. Cow dung contains rich ingredients such as cellulose, which can improve the soil structure. The nutrients in the composite biofertilizer can supplement the nitrogen, phosphorus, potassium and other elements required for the growth of fruit trees. It is suitable for soils with heavy texture. Cow dung can improve the air permeability and water permeability of the soil, and the composite biofertilizer can supplement nutrients for the soil. The combination of the two helps to improve the physical properties of heavy soil and create a good environment for the growth of fruit tree roots.
