Biological organic fertilizer and preparation method and application thereof

Abstract

The invention provides a biological organic fertilizer and a preparation method thereof. The biological organic fertilizer is prepared from decomposed organic matters, wood rotting fungus hyphae, plant ash and organic calcium phosphate. By adoption of the plant ash and the decomposed organic matters as matrixes, nutrients generated by the organic matters decomposed by wood rotting fungi provide fertilizers for crops, and loose space is provided for crop root system growth by organic matter rotting, so that soil loosening is realized while crop growth is promoted. The preparation method of thebiological organic fertilizer includes steps of decomposed organic matter preparation and the like. The method is simple in process and high in organic matter decomposing efficiency, and accordingly abiological organic fertilizer preparation period is maximally shortened.

Description

technical field [0001] The invention relates to the technical field of bio-organic fertilizer, in particular to a bio-organic fertilizer and its preparation method and application. Background technique [0002] Fertilizer is a kind of substance that provides one or more essential nutrients for plants, improves soil properties, and improves soil fertility. It is one of the material basis of agricultural production. The extensive use of inorganic fertilizers in agricultural production will make the environment worse. 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, so it is difficult to meet the actual growth needs of...

Problems solved by technology

However, the long-term use of chemical fertilizers in large quantities will increase the dependence of crops on chemical fertilizers year by year, and the ground fertilizer will become less and less. When chemical fertilizers are used to irrigate crops, the actual utilization rate is only 35%, and the remaining part will be volatilized into the atmosphere or flow with water. It flows into rivers and lakes, causing environmental problems such as soil compaction, air pollution, and water pollution. It poses a serious threat to the health and survival of humans and other organisms.

After the soil is compacted, the root system of the crops will be hypoxic and their vitality will decrease, and they will not grow normally. The respiration of the root cells of the plants will be weakened, and nutrients such as nitrogen exist in the ion state. The energy produced by cell metabolism will be consumed during absorption, and the respiration will be weakened, so the energy Insufficient supply, affecting nutrient uptake; soil compaction can also lead to nutrient deficiency in crops

[0004] Moreover, there is no perfect treatment mechanism for crop waste generated in the process of agricultural production. For example, wastes such as corn stalks, wheat stalks, and rice straws, which are increasingly prominent, are burned by traditional treatment methods and bring huge pollution to the atmosphere.

[0005] In the prior art, there is a lack of bio-organic fertilizers that can simultaneously solve crop waste pollution and soil compaction
