Production of Organic Particle Fertilizer Using Livestock Manure Straw

As one of the important sources of agricultural production, organic fertilizer plays an important role in improving the quality of agricultural products. The Longjiang County of Heilongjiang Province is a farming and grazing county that combines planting and aquaculture and produces a large amount of organic fertilizer resources such as crop stalks and livestock and poultry manure every year. The Shenghua Green Organic Fertilizer Factory of the Longjiang County Fertilizer Association takes the county agricultural technology promotion center as the technical support unit, and uses the organic fertilizer resources as the carrier. Since 1995, it has produced about 6 000 tons of organic granular fertilizer, and the annual application area has been between 1.8 and 20,000. Hm2, welcomed by local farmers. 1 Production Technology Section 1.1 Straw Crush In the three months of July, August and September, the corn stalks of corn and sorghum harvested in the previous year were crushed into small pieces of 1 to 3 cm in size by a crusher, and then directly transferred to the second production link. 1.2 Fermentation Decomposition The comminuted small pieces of straw and the unfermented mature human, livestock and poultry manure and the fermentation of the fields, the head, the ditch side, the Tuenbu firewood, and the green grass are fermented. Fermentation and decomposing method should adopt the method of pooling and cover the manure pool with cover to prevent and reduce nutrient volatilization, and then directly transfer to the third production link. 1.3 Dry and mix the raw materials that are fermented and cooked in the same batch of different fertilizer tanks and remove them, put them on the cement floor with a shade drying rack to prevent them from being directly exposed to sunlight and reduce nutrient volatilization. In order to make the nutrients even, we must mix it while wetting. After being dried, it goes directly to the fourth production link. 1.4 Raw materials are sieved. The dried raw materials are sieved with a 0.3-0.7 mm sieve. Annual production of fertilizer can be used for artificial screening, and the annual production capacity can be used for mechanical sieves. The sifted noodles are bagged in a raw material store as a carrier for formulating fertilizers. Each batch of mature fermented carriers should be marked and recorded in batches and stored in batches. Because there are differences in nutrient content and nutrient types in each batch of carriers. 1.5 Carrier Test The carriers that have been screened and formulated with fertilizers will be tested separately according to different batches fermented and decocted, that is, batches of batches of fermentation will be tested to provide basis for the formulation. 1.6 Soil Testing Formulation According to the topography of the cultivated land and the type of soil to test the soil, test its nutrient type and nutrient content, determine the target yield, and formulate the fertilizer formula based on the carrier test and soil test results. 1.7 Feeding and granulation feeding In tons, according to the formula, the N, P, K and other nutrient raw material fertilizers will be converted into physical quantities and tons of commodity quantities, that is, the proportion of the raw material commodities needed to produce each ton of fertilizer. For each production of 5t or 10t feed 1 time. After mixing, it should be stirred evenly, granulated with disc pelletizer, and transferred directly to the eighth production link. 1.8 Drying test In order to reduce the nutrient volatilization, it is best to place organic fertilizer produced in the shade on a drying platform with yin and drying. The annual output is less natural and dry. More annual production can be used for mechanical drying. After drying, batches of organic granular fertilizer produced by fermentation and decomposing were sampled and tested separately to check whether the nutrient type and nutrient content were consistent with the formula. 1.9 Screening and Drying of Finished Product The organic granular fertilizer after the test is allowed to enter the sifting stage (it is also possible to pass the screening after screening). The annual production capacity can be reduced by manual sieving. The annual production volume can be sieved by machinery. 1.10 Finished bagged organic granulated fertilizer products enter the final stage, namely bagging, sealing and storage in the finished product warehouse. 2 Some explanations (1) From the 7th to the 10th production stage, the conveyor can be used as needed to facilitate continuous operation to suit large-scale production. (2) For mass production, mechanical drying can be used throughout the year. (3) From June to September, all the raw materials needed for the next year's production will be fermented, dried, mixed, sieved, and tested for storage, so as to ensure that raw materials for organic fertilizer production are adequate in the next year.
