Using advanced composting fermentation technology, inoculation of high-speed and high-efficiency fermenting agent, the straw cellulose is rapidly decomposed and transformed, and various pathogens, weed seeds and aphid eggs are killed, and the production stability is strong and the nutrient species are complete. Organic Fertilizer. The bio-organic fertilizer produced by straw and manure contains a large number of elements such as nitrogen, phosphorus and potassium required for crop growth, and contains trace elements such as sulfur, calcium, magnesium, zinc, boron, molybdenum, copper and iron, and most of them are organic. Form exists. It can not only meet the needs of crop growth, but also improve the ability of crops to adapt to adverse environments. Compared with chemical fertilizers, organic fertilizers are characterized by no fertilizer, no deficiency, stable supply, and long-acting effects. The straw waste can be treated harmlessly, and the bio-organic fertilizer can be used to increase production and increase efficiency, so as to achieve the unification of ecological benefits and economic benefits. In general, the application of this fertilizer can increase crop yield by 5 to 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, in the case of ensuring the same yield, the amount of fertilizer applied can be reduced by 30% to 40%, that is, the input is reduced by 20 to 50 yuan/mu. Technical points: (1) straw treatment should first smash the straw to a certain degree of fineness, and then must also add appropriate amount of raw materials such as poultry manure or sludge to adjust the carbon-nitrogen ratio and moisture of the compost material, or add bacteria. And enzymes. (2) Fermentation is divided into two stages: one is pre-fermentation, which can be carried out in the open air or in the fermentation device. The oxygen is supplied to the accumulation layer or the fermentation device by turning the forced ventilation, and the livestock and poultry feces are added as the main body of the straw. The main fermentation period of oxygen compost is about 3 to 10 days. The second is post-fermentation. After the semi-finished product of the main fermentation is sent to the post-fermentation process, the easily decomposable organic matter which has not been decomposed in the main fermentation process and the organic matter which is difficult to be decomposed are further decomposed to become stable organic substances such as humic acid and amino acid. Fully decomposed organic fertilizer products, the post-fermentation time is usually more than 20 to 30 days. (3) Post-treatment It can be further dried and pulverized as needed, and then processed into a crop-specific organic-inorganic compound fertilizer. (4) Storage Composting is generally used in spring and autumn, and must be accumulated in summer and winter. The storage method can be directly piled up in the fermentation tank or in bags, requiring dry and breathable. Appropriate area: This technology can be promoted in China's straw-rich grain producing areas and areas with limited environmental capacity, especially for urban and rural areas where environmental problems are more prominent.
