Abstract
The invention discloses an organic fertilizer for improving soil microbial biomass and enzyme activity and a preparation method thereof, belonging to the technical field of organic fertilizer preparation, wherein the organic fertilizer comprises the following components in parts by weight: 7-8 parts of bone powder, 3-5 parts of diatomite, 1-3 parts of seaweed powder, 4-5 parts of mixed residue powder, 7-9 parts of bean curd residue, 3-5 parts of seaweed liquid, 4-5 parts of fruit residue and 10-20 parts of mixed compost, wherein the preparation method comprises the steps of S1, preparing mixed powder; s2, preparing an organic fertilizer; the organic fertilizer disclosed by the invention contains rich nutrient components such as nitrogen, phosphorus, potassium and trace elements, can effectively improve the soil fertility, can improve the absorption and utilization rate of the nutrient elements by crops, can increase the number of soil microorganisms, promote the microbial activity, regulate the soil fertility balance and stabilize the environment of soil moisture.
Description
Technical Field
The invention relates to the technical field of organic fertilizer preparation, in particular to an organic fertilizer for improving soil microbial biomass and enzyme activity and a preparation method thereof.
Background
Organic fertilizers are also known as "farmyard manure". Organic fertilizers are known as organic fertilizers using organic substances (compounds containing carbon elements) as fertilizers. Including human manure, compost, green manure, cake manure, biogas manure, and the like. Has the characteristics of multiple types, wide sources, longer fertilizer efficiency and the like. The organic fertilizer contains a plurality of nutrient elements in an organic state, so that crops are difficult to directly utilize, and the nutrient elements are slowly released under the action of microorganisms to continuously supply the nutrients to the crops. The application of the organic fertilizer can improve the soil structure, coordinate water, fertilizer, gas and heat in the soil, and improve the soil fertility and the land productivity.
The organic fertilizer is prepared from by-product resources rich in organic matters such as animal excreta or animal and plant residues as main raw materials by fermenting and decomposing. The organic fertilizer has the characteristics of improving soil, improving fertility, improving soil nutrient activity, purifying soil ecological environment, guaranteeing high quality, high yield and high benefit of vegetables and the like, and is an irreplaceable fertilizer for facility vegetable cultivation. Organic fertilizers commonly used for facility vegetable cultivation mainly include commercial organic fertilizers and farmyard fertilizers.
The existing organic fertilizer mostly adopts farmyard manure, has bad smell and poor effect, has limited effect on improving soil, is difficult to change soil quality, and most of soil has continuously reduced fertility under the planting of common crops, has reduced microbial content and low activity of microbial enzyme, so the organic fertilizer for improving soil has good effect and improving microbial content and enzyme activity of soil is needed.
Disclosure of Invention
In order to solve the technical problems, the invention provides an organic fertilizer for improving soil microbial biomass and enzyme activity, which comprises the following components in parts by weight: 7-8 parts of bone meal, 3-5 parts of diatomite, 1-3 parts of seaweed powder, 4-5 parts of mixed residue powder, 7-9 parts of bean curd residue, 3-5 parts of seaweed liquid, 4-5 parts of fruit residue and 10-20 parts of mixed compost;
the preparation method of the mixed residue powder comprises the following steps:
recycling waste residues of a peanut oil plant to obtain peanut residues, recycling kitchen waste to obtain kitchen waste, mixing the peanut residues and the kitchen waste in a mixer according to a mass ratio of 2:1 to obtain a mixture, mixing the mixture with water according to a mass ratio of 1:2, adding the mixture into a pressure cooker to perform high-pressure cooking, performing filter pressing on the mixture in the pressure cooker after the cooking is finished to obtain filtrate and filter residues, placing the filter residues into a pulverizer, wherein the rotating speed of the pulverizer is 800-1000r/min, the pulverizing duration is 20-30min, obtaining pulverized materials after the pulverizing is finished, drying the pulverized materials at a drying temperature of 60-80 ℃ for 10-20h, and obtaining mixed residue powder after the drying is finished;
the preparation method of the mixed compost comprises the following steps:
mixing the filtrate produced in the preparation of the mixed residue powder with plant straws according to the mass ratio of 3:5 for composting, continuously fermenting for 20-30 days at the temperature of a composting center of 55-60 ℃, stirring in the fermentation process, continuously adding the mixture filtrate to keep the humidity of a compost pile at 60-70%, adding animal manure after the fermentation is finished, wherein the mass ratio of the addition of the animal manure to the plant straws is 1:5, stirring the compost pile to uniformly mix the animal manure with the compost pile, and continuously standing for fermenting for 2-3 months to obtain the mixed compost.
