Straw production of bio-organic fertilizer technology
Advanced compost fermentation technology is used to inoculate high-speed and high-efficiency fermenting agents, so that the straw cellulose is rapidly decomposed and transformed, and various pathogenic bacteria, weed seeds and roundworm eggs are killed, and the production of stable and nutrient-rich organisms is completed. Organic Fertilizer. Bio-organic fertilizers produced from straw and manure contain large quantities of nitrogen, phosphorus, and potassium needed for crop growth. They also contain trace elements such as sulfur, calcium, magnesium, zinc, boron, molybdenum, copper, and iron, and are mostly organic. Form exists. It can not only meet the needs of crop growth, but also improve the adaptability of crops to adverse environments. Compared with chemical fertilizers, organic fertilizers have the characteristics of no fertilizer, no shortage of nutrients, stable supply and long-term efficacy. It can not only make the straw waste harmless, but also increase the production and efficiency through the biological organic fertilizer, and achieve the unity of ecological benefits and economic benefits. Under normal circumstances, applying this fertilizer can increase crop yield by 5-20%. Due to the high utilization rate of organic fertilizer, nitrogen can reach 70-80% and phosphorus can reach 80-90%. Therefore, compared with chemical fertilizers, fertilizer production can be reduced by 30% to 40% while ensuring the same yield, that is, reducing input by 20-50 RMB/mu.
Technical points: (1) The straw should first be crushed to a certain degree of fineness, and then must be added to the amount of raw materials such as poultry urine or sludge to adjust the carbon-nitrogen ratio and moisture of the compost material, or to add bacteria Species and enzymes. (2) Fermentation is divided into two stages: First, pre-fermentation can be carried out in open air or in a fermentation plant, and oxygen is supplied to the accumulation layer or the fermentation device by means of forced-air ventilation, and straw-based animal manure is added. The main fermentation period of oxygen compost is about 3-10 days. The second is post-fermentation. After the semi-finished products from the main fermentation are sent to the post-fermentation process, the undecomposed organic substances that have not been decomposed in the main fermentation process and the organic compounds that are more difficult to decompose are further decomposed to become stable organic substances such as humic acids and amino acids. Completely decomposed organic fertilizer products usually have a post-fermentation time of more than 20-30 days. (3) After treatment, it can be further dried and crushed as needed, and then processed into crop-specific organic-inorganic compound fertilizers. (4) Storage Compost is generally used in spring and autumn. It must be stored in summer and winter. The storage method can be piled directly in the fermentation tank or in bags, requiring dry and breathable. Appropriate area: This technology can be popularized in China's food-producing areas with limited straw resources and areas with limited environmental capacity, and is particularly suitable for use in urban-rural areas where environmental issues are more prominent.
The valve is a series of gas emergency shut off solenoid valves, specially designed as gas pipe breaker for emergency use. It can be connected with gas leaking detection sensor, fire alarm circuit or other intelligent sensor modules so that on site or remote shut down on gas supply (manually or automatically) is possible, hence ensuring the safety on gas usage. The valve features an auto-close when strong vibration is detected. After close, manual operation is required to turn on the valve. This feature meets safety regulations in the event of an accident.
