The straw production organic fertilizer production line adopts advanced compost fermentation technology and organic fertilizer production machine, inoculated with high-speed and high-efficiency fermentation inoculants, so that the straw cellulose can be quickly decomposed and transformed, and various pathogens, weed seeds and roundworm eggs are killed, and the production is stable and nutrient a complete range of bio-organic fertilizers. Compared with chemical fertilizer, organic fertilizer has the characteristics of no partial fertilizer, no shortage of nutrients, stable supply and long-term effect. Not only can the straw waste be treated harmlessly, but also the production and efficiency of bio-organic fertilizer can be increased to realize the unification of ecological and economic benefits.
Key points of straw processing organic fertilizer production line technology:
(1) Straw treatment. First, the straw pulverizer should crush the materials to a certain degree of fineness, and then an appropriate amount of poultry manure or sludge must be added to it to adjust the carbon-nitrogen ratio and moisture of the compost material, or add bacteria and enzymes.
(2) Fermentation. It is divided into two stages: the first is pre-fermentation, which can be carried out in the open air or in a fermentation device. The stacking layer or the fermentation device is supplied with oxygen through forced ventilation by turning over, the straw is the main body, livestock and poultry manure is added, and the main fermentation of aerobic composting The period is about 3 to 10 days. The second is post-fermentation. The semi-finished products after the main fermentation are sent to the post-fermentation process to further decompose the easily decomposable organic matter and the more difficult-to-decompose organic matter that have not been decomposed in the main fermentation process to turn them into stable organic matter such as humic acid and amino acid. For fully decomposed organic fertilizer products, the post-fermentation time is usually more than 20-30 days.
(3) Post-fermentation treatment. It can be further dried and crushed as needed to turn the materials into qualified organic fertilizer raw materials.
(4) Storage. Compost is generally used in spring and autumn, and must be accumulated in summer and winter. The storage method can be directly piled in the fermentation tank or in bags, requiring dryness and ventilation.
The above are the key points to be paid attention to when processing organic fertilizer with straw. This method is suitable for promotion in the grain production areas with abundant straw resources and areas with limited environmental capacity in my country, especially suitable for urban and rural areas where environmental problems are more prominent.
