Formula of compound biological bacterial fertilizer and preparation process and application thereof

Abstract

The invention relates to a formula of a compound biological bacterial fertilizer and a preparation process and application thereof. The formula of the compound biological bacterial fertilizer comprises, by weight, 10-60 parts of pre-cooking fluid, 10-25 parts of azotobacter chroococcum inoculum, 10-25 parts of bacillus mucilaginosus inoculum, 10-25 parts of bacillus megaterium inoculum and 10-25 parts of bacillus thuringiensis inoculum, wherein the pre-cooking fluid is a nutrient solution obtained by treating industrial wastewater produced in the edible fungi canning and processing process. The formula of the compound biological bacterial fertilizer has the following advantages that the formula is capable of saving energy and is environmentally friendly; the applying quantity of a chemical fertilizer is effectively decreased; the bacterial fertilizer can prevent soil hardening; the bacterial fertilizer further has the insect prevention and controlling effects; the preparation process is simple and is suitable for industrial production; the compound biological bacterial fertilizer can be stored for a long period of time and does not easily inactivate.

Description

technical field [0001] The invention relates to a formula, a production process and an application of a composite biological bacterial fertilizer. Background technique [0002] Food is the most important thing for the people. Food and vegetables are the most basic and necessary material materials for human beings to survive. Traditional methods such as the amount of fertilizer used and the amount of pesticides used are unsustainable, and there are many problems such as high cost, global warming, environmental pollution, and food safety; [0003] The use of bacterial fertilizer is not only conducive to increasing crop yield, improving soil moisture, increasing the content of total nitrogen, phosphorus, potassium, sodium and organic matter in the soil, but also enhancing soil fertility. It is an eco-friendly, low-cost, high-efficiency, Sustainable, globally accepted green agricultural production methods; [0004] However, the current production of bacterial fertilizer genera...

AI Technical Summary

Problems solved by technology

[0004] However, the current production of bacterial fertilizer generally has the following problems: 1. Starch, corn flour, etc. are mainly used as carbon sources. In the case of increasingly tight food supply, it is difficult to achieve sustainable development in the long run, and there are high production costs and low utilization. Low efficiency; 2. Some bacterial fertilizers use organic matter such as domestic garbage, poultry, livestock manure, and leftovers as production substrates, which generally have disgusting odors; 3. The effective bacteria in bacterial fertilizers are single, such as Phosphorus or potassium-dissolving effective strains; 4. The compound bacterial fertilizer needs to add other nutrients, which increases the production cost;

[0005] In addition, the industrial wastewater generated during the edible fungus canning process is often rich in some nutrients such as amino acids, minerals, sugars, etc. If the wastewater is discharged after treatment, it will not only require expensive sewage treatment costs, but also caused a certain waste of resources
