Organic fertilizer and preparation process thereof

Abstract

The invention relates to a preparation process of organic fertilizer. The preparation process of the organic fertilizer comprises the following steps: S1, respectively weighing corresponding components according to weight; S2, uniformly mixing the weighted components and composting; S3, carrying out primary fermentation; S4, carrying out secondary fermentation; S5, sieving and processing; S6, granulating; S7, drying; S8, cooling; and S9, packaging. The preparation process of the organic fertilizer has the beneficial effects that the organic fertilizer is prepared by successively carrying out the primary fermentation and the secondary fermentation, the organic fertilizer has the advantages of rapid absorption to crops, low loss and rain erosion resistance, the secondary peak absorption can be achieved, the purposes of increasing yield and increasing income can be achieved, meanwhile, the organic fertilizer is green and environmentally friendly and is free of heavy metals, and the diseases such as cholesterol, hypertension and the like can be resisted after people eat the crops planted with the organic fertilizer.

Description

technical field [0001] The invention relates to the field of planting, in particular to an organic fertilizer and a production process thereof. Background technique [0002] At present, the world is facing severe problems of population increase and environmental degradation, and the extensive use of inorganic fertilizers in agricultural production will also make environmental degradation more serious. The deficiencies of this inorganic fertilizer mainly include: destroying the soil, resulting in a decrease in the content of soil organic matter, an imbalance in the proportion of various nutrients, acidification and compaction of the soil, and serious damage to the physical and chemical properties of the soil and soil microbial flora, resulting in its water retention. Fertilizer and air permeability are poor, which is difficult to meet the actual growth needs of crops; crops are highly dependent on chemical fertilizers and pesticides, and the amount of use must be increased ye...

Problems solved by technology

The deficiencies of this inorganic fertilizer mainly include: destroying the soil, resulting in a decrease in the content of soil organic matter, an imbalance in the proportion of various nutrients, acidification and compaction of the soil, and serious damage to the physical and chemical properties of the soil and soil microbial flora, resulting in its water retention. Fertilizer and air permeability are poor, which is difficult to meet the actual growth needs of crops; crops are highly dependent on chemical fertilizers and pesticides, and the amount of use must be increased year by year; After farmland, the actual utilization rate is only 30% on average, and most of it flows into rivers and lakes with farmland drainage or remains in the soil, plants and crops, which not only brings environmental pollution but also endangers the safety and health of human beings and lives. These have become sustainable agriculture. Obstacles to sexual development; the above situations can be improved by using organic fertilizers, but there are many varieties of organic fertilizers in China. The dosage is very small, it cannot be used as the main fertilizer, and the effect is single, and the price is high
