Organic fertilizer and preparation method thereof

Abstract

The invention belongs to the technical field of fertilizers, and particularly relates to an organic fertilizer and a preparation method thereof. The organic fertilizer is composed of the following components in parts by mass: 40-80 parts of silkworm litter, 50-100 parts of wet pond silt, 5-15 parts of snail shell, 10-20 parts of straw, 15-25 parts of animal manure, 5-10 parts of microbial fermentation bacterium and 5-10 parts of aboriginal bacterium. The organic fertilizer is convenient in production and application methods, and is safe and effective. The verification proves that the organic fertilizer has the characteristics of enhancing the crop yield, reducing the chemical fertilizer and pesticide consumptions and the like. The organic fertilizer is prepared by carrying out compost fermentation on the silkworm litter and snail shell under the action of the microbial fermentation bacterium and aboriginal bacterium, can solve the problems of soil solidifying and hardening due to long-term use of the chemical fertilizer and pesticide, and can effectively enhance the crop quality.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to an organic fertilizer and a preparation method 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...

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
