Technical Field

[0001] The invention relates to the technical field of biological fermentation fertilizers, in particular to a biomass microbial fermentation fertilizer and a preparation method thereof. Background Art

[0002] Bio-organic fertilizer refers to a type of fertilizer that has the effects of both microbial fertilizer and organic fertilizer, which is a combination of specific functional microorganisms and organic materials that are mainly derived from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and have been harmlessly treated and decomposed.

[0003] Food industry by-products are usually discarded, but they contain a large amount of nutrients. If they are directly discarded, they will not only cause environmental pollution and endanger people's health, but also cause waste of biological resources and increase the cost of processing food industry by-products.

DETAILED DESCRIPTION

[0011] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0012] The invention provides a biomass microbial fermentation fertilizer, which comprises, by weight, 2 parts of fish oil, 2 parts of fish intestines, 2 parts of fish gills, 2 parts of fish scales, 3 parts of peanut shells, 3 parts of peanut kernels, 8 parts of bean dregs, 20 parts of water and 40 parts of EM bacterial liquid.

[0013] A preparation method of biomass microbial fermentation fertilizer: Step 1: Place 2 parts of fish oil, 2 parts of fish intestines, 2 parts of fish gills, 2 parts of fish scales, 3 parts of peanut shells, 3 parts of peanut kernels, and 8 parts of bean dregs into a mixing tank, and then add 20 parts of water to mix and stir; Step 2: After mixing, seal the mixing tank and sterilize at 125 degrees Celsius for 30 minutes; Step 3: After sterilization, cool the mixing tank. After cooling to room temperature, add 40 parts of EM bacterial solution for fermentation. After fermentation, it will be made into fermented liquid organic fertilizer.

[0014] The EM bacterial solution in step three can be placed according to a material-liquid ratio of 1:3, 1:4.5, 1:5.5 and 1:6.5.

[0015] In the step 3, the fermentation time is selected to be 6, 8, 12, or 14 days.

[0016] The fermented liquid organic fertilizer prepared in step 3 is placed in a filter, and the precipitated impurities in the fermented liquid organic fertilizer can be filtered, and the filtrate after filtration is stored separately.

[0017] The fermentation time of organic fertilizer needs to be controlled. It cannot be too short, which will result in insufficient fermentation. If the fermentation time is too long, the death rate of different bacteria will be accelerated, thus slowing down the fermentation rate, and there will be a reduction in bacteria in the fermented liquid organic fertilizer.

[0018] The material-liquid ratio of 1:3, 1:4.5, 1:5.5 and 1:6.5 is more conducive to the reproduction and growth of microorganisms. A too low material-liquid ratio will lead to a relatively high concentration of bacteria, resulting in too low oxygen content in the fermentation liquid, which is not conducive to fermentation and decomposition. A too high material-liquid ratio will affect the metabolism of microorganisms and dilute the concentration of organic matter generated by decomposition.

[0019] The fermented fertilizer prepared under optimal conditions is slightly alkaline, which can improve the soil pH and is suitable for acidic soil or soilless matrix. At the same time, the fertilizer has a high organic matter content and rich nutrients, which can provide sufficient nutrient sources for the soil or soilless matrix, thereby improving the quality of crops.

[0020] Before preparing fermented fertilizer, bean curd dregs need to be prepared. During the preparation, the dryer and the soy milk press are connected with a pressure pump, and the soy milk press continuously transfers fresh bean curd dregs to the dryer, so as to achieve drying of the bean curd dregs in a short time. In this drying system, the fresh bean curd dregs are transmitted to the hopper by the air pressure device, and then quantitatively transferred from the feeding hopper to the rotary feeder, and enter the drum dryer for drying. The drum dryer is fed with propane gas combustion heat by the blower. The bean curd dregs are crushed and dehydrated by ceramic balls in the dryer, and then enter the grading chamber for grading and drying, and finally the dried bean curd dregs are recovered by the cyclone separator.

[0021] The fermented liquid organic fertilizer prepared in the step 3 is taken out into a test tube and measured by colorimetry. The pH value of the fermented liquid organic fertilizer is measured by a pH meter. The soil matrix treated with fermented fertilizer is more conducive to metabolism and growth and development. As crops grow, the content of reduced vitamin C per unit mass continues to increase. The organic fertilizer prepared by fermenting fish scraps, peanut meal and bean dregs contains a large amount of nutrients such as amino acids, carbohydrates and nitrogen, phosphorus and potassium, which is conducive to improving the quality of crops and is rich in calcium sources. With fish oil, fish intestines, fish gills, fish scales, peanut shells, peanut kernels, bean dregs and water as raw materials, EM bacteria are added to prepare fermented liquid organic fertilizer, which improves the utilization rate of food industry by-products and reduces the use of chemical fertilizers in the process of crop cultivation.

[0022] When preparing fermented fertilizer, peanut shells and peanut kernels need to be crushed to make peanut meal. Peanuts are selected as raw materials during preparation to ensure the quality of peanut meal. The crushed peanuts are peeled by a peeling machine to remove the outer shell on the surface of the peanut kernels, and then the peanuts are deslagging by a vibrating screen to remove impurities such as sand and dust in the peanut meal. The peanut kernels are then pre-baked and defatted to remove the oil components. The defatting process can be carried out by pressing, leaching, etc. Finally, the defatted peanut kernels are dried to reduce their moisture content to an appropriate range. Commonly used drying methods include natural air drying and mechanical drying. Mechanical drying usually uses low-temperature drying to avoid damage to the nutrients in the peanut meal.
