Organic fertilizer

Abstract

The invention discloses an organic fertilizer which comprises straws, coal gangue, decomposed coal, peat soil, ground phosphate rock, potassium ore powder, wheat middling, soybean meal, rice hull powder, culture powder, urea and polyacrylamide. The organic fertilizer integrates yield increase, high efficiency, long action and capacities of improving quality, improving soil and inhibiting soil-borne diseases into a whole, is low in cost, simple in process and free of residues and pollution and has high popularization and application prospects.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to 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 year; After far...

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
