High-efficiency organic fertilizer

Abstract

The invention discloses high-efficiency organic fertilizer which comprises straw, gangue, windblown coal, peat soil, ground phosphate rock, ground potassium ore, soybean meal, rice hull powder, strainpowder, urea and polyacrylamide. The organic fertilizer integrates yield increase, high efficiency, long acting, quality improvement, soil improvement and inhibition of soil-borne diseases, is low incost, simple in technology and free from residue and pollution and has better popularization and application prospects.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to high-efficiency organic fertilizers. 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 year by ...

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 high-efficiency organic fertilizers, but there are many varieties of high-efficiency organic fertilizers in China. The amount of application is very small, it cannot be used as the main fertilizer, and the effect is single, and the price is high
