Bio-fertilizer

Abstract

The invention provides a bio-fertilizer, comprising the following effective components in parts by weight: 5-55 parts of coal gangue particles, 5-50 parts of peat soil, 10-30 parts of coal ash, 5-15 parts of pond silt particles, 30-75 parts of plant ashes, 20-30 parts of straw powder, 15-55 parts of excrements of livestock and poultry and 0.1-5 parts of bacteria powder. The bio-fertilizer provided by the invention integrates yield increase, high efficiency, long acting, quality improvement, soil improvement and soil-borne disease inhibition, is low in cost, simple in process, free of a residue, and free of pollution, and has relatively good popularization and application prospects.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a biological fertilizer, which belongs to the field of agricultural means of production. 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 ...

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 conditions can be improved by applying organic fertilizers, but there are many varieties of organic fertilizers in China. Single function, high price
