Liquid Fertilizer Fermentation Process: 95% High-Yield Rate Implementation Guide
With the rapid development of green agriculture, organic liquid fertilizer has become a key product to replace chemical fertilizers and improve soil quality, and the liquid fertilizer fermentation process directly determines the nutrient content, stability and safety of the product.Through in-depth analysis of the liquid fertilizer fermentation process and precise control of key parameters, it is possible to achieve a 95% high-yield rate, reduce production costs and improve market competitiveness. Below is a detailed explanation of the key content of the liquid fertilizer fermentation process.
Core principle of liquid fertilizer fermentation process
The liquid fertilizer fermentation process is a biological reaction process that uses microorganisms to decompose and transform organic raw materials under certain temperature, humidity and oxygen conditions. The core principle is that microorganisms decompose complex organic matter in raw materials into small-molecule nutrients that can be directly absorbed by crops, while inhibiting the reproduction of harmful bacteria.
Key steps of liquid fertilizer fermentation process
The liquid fertilizer fermentation process is a systematic project that requires strict control of each link. The key steps and operation points to ensure a 95% high-yield rate are as follows:
- Raw material selection and pretreatment
The selection of raw materials directly affects the fermentation effect. Common raw materials include livestock and poultry manure,crop straw and so on.It is necessary to ensure that the raw materials are fresh and free of toxic and harmful substances.Then we should change the carbon-nitrogen ratio into a suitable proportion and control the temperature and moisture in a certain degree,ensuring the activity of microorganisms and avoid anaerobic fermentation caused by excessive moisture.The common machines are mixer and crusher.
- Fermentation agents addition
To improve the fermentation efficiency and product quality,adding high-quality fermentation agents which can significantly improve the fermentation efficiency and product quality is really significant.
- Fermentation environment control
Temperature and oxygen are the core parameters of the fermentation process. The fermentation temperature should be controlled at 35-45℃, which is the optimal temperature range for beneficial microorganisms.For anaerobic fermentation, it is necessary to ensure the tightness of air of the fermentation tank to avoid oxygen entering and affecting the fermentation effect.
- Fermentation process monitoring
During the fermentation process, it is necessary to regularly monitor the temperature, pH value and odor of the materials. Normal fermentation materials will have a sour and sweet smell and the pH value should be controlled at 6.5-7.5.
- Post-fermentation treatment
After the fermentation is completed, the materials need to be filtered to remove impurities such as sediment and residues.For further improving the product quality, the filtrate can be subjected to secondary fermentation to make the nutrients more stable. Finally, appropriate functional additives can be added according to the product requirements to prepare liquid fertilizers of different specifications.
Common problems and solutions in liquid fertilizer fermentation process
In the actual operation of the liquid fertilizer fermentation process, various problems are likely to occur, which affect the product yield and quality. The following are common problems and corresponding solutions:
Slow fermentation speed:The main reasons are low temperature, inappropriate carbon-nitrogen ratio, and low fermentation agent activity. Only proper parameter of these indications can speed up fermentation process.
Low nutrient content of products:The main reasons are incomplete fermentation and insufficient raw material nutrients. The solution is to extend the fermentation period, add high-nutrient raw materials, and optimize the temperature and pH parameters.
Product deterioration during storage:It is mainly caused by incomplete fermentation and the presence of harmful bacteria. If product has deterioration during storage,secondary fermentation is needed to kill harmful bacteria.
Application scenarios of liquid fertilizer fermentation process
The liquid fertilizer fermentation process has a wide range of application scenarios, covering various types of liquid fertilizer production, mainly including:
Organic liquid fertilizer production:Through the liquid fertilizer fermentation process, organic liquid fertilizers rich in humic acid and amino acids are produced, which are widely used in grain crops, vegetables and fruits.
Seaweed liquid fertilizer production:Taking seaweed as the main raw material, through the liquid fertilizer fermentation process, the active ingredients in seaweed are extracted, and the produced seaweed liquid fertilizer has the effect of promoting crop growth and enhancing stress resistance.
Biological bacterial fertilizer production:Through the liquid fertilizer fermentation process, beneficial microorganisms are multiplied in large quantities, and the produced biological bacterial fertilizer can improve the soil microbial community structure and inhibit the occurrence of soil-borne diseases.
Frequently Asked Questions (FAQs) About Liquid Fertilizer Fermentation Process
Q1: What is the optimal temperature for the liquid fertilizer fermentation process?
A1: The optimal temperature is 35-45℃, which can ensure the high activity of beneficial microorganisms and improve fermentation efficiency.
Q2: How to judge whether the liquid fertilizer fermentation process is completed?
A2: It can be judged by three indicators: the temperature of the materials drops to room temperature, the materials have a sour and sweet smell, and there is no obvious undegraded residue.
Q3: Can the fermentation agent be reused in the liquid fertilizer fermentation process?
A3: It is not recommended to reuse it directly. The activity of microorganisms in the used fermentation agent decreases, and the number of beneficial bacteria is insufficient, which will affect the fermentation effect.
Q4: What is the impact of moisture content on the liquid fertilizer fermentation process?
A4: The optimal moisture content is 60%-65%. Too high moisture will cause anaerobic fermentation, and too low moisture will reduce microbial activity and slow down fermentation.
Q5: How long is the general cycle of the liquid fertilizer fermentation process?
A5: The general cycle is 7-15 days, which varies according to raw material type, temperature and fermentation agent activity.
Conclusion
The liquid fertilizer fermentation process is the core of liquid fertilizer production, and scientific and standardized operation is the key to achieving a 95% high-yield rate.By mastering the core principles, key steps and parameter optimization tips of the fermentation process, and effectively solving common problems in the fermentation process, enterprises can stably produce high-quality liquid fertilizer products, reduce production costs and improve market competitiveness.
