Slow-release biological organic fertilizer

Abstract

The present invention discloses a slow-release biological organic fertilizer, which is characterized by comprising the following raw materials by weight: 20-30% of Perilla Frutescens seed, 6-10% of hemp seed, 5-10% of fly ash, 15-25% of an organic matter, 10-15% of a high barrier property organic matter, 10-20% of an amino resin-expanded graphite complex, 5-10% of a degradable polymer, 5-8% of a silicate mineral, and 10-20% of humic acid. According to the present invention, the silicate mineral, the biological fertilizer and other components are integrated, such that characteristics of rich nutrition variety, strong crop specificity, stable physical and chemical indicators, excellent interaction, efficiency, fast-acting property, long-acting property, no toxicity, and wide application are provided; the amino resin-expanded graphite complex is adopted as the film forming substance, such that the release period of the fertilizer is increased, and the fertilizer efficiency of the fertilizer of the present invention is equal to or higher than the fertilizer efficiency of the fertilizer in the prior art; and the plant diseases and the insect pests of the crops are reduced, the stress resistance is enhanced, the film body is the fertilizer material, and no harm is produced to the environment.

Description

technical field [0001] The invention belongs to the field of chemical fertilizer industry, and in particular relates to a slow-release bio-organic fertilizer. Background technique [0002] Slow-release chemical fertilizers meet the requirements of environmental protection and sustainable social development, and will become the mainstream of agricultural chemical fertilizers in the future and the development direction of agricultural chemical fertilizers in the world. However, most of the coatings of slow-release chemical fertilizer products cannot be degraded. For example, coatings such as epoxy resin, polyurethane, polyethylene, polypropylene, and polyvinyl chloride will remain in the soil and pollute the environment. In particular, most of the coatings are not fertilizers. Substances that are useless to crops. The development of fertilizer-encapsulated slow-release chemical fertilizers is a good expectation in the field of coated slow-release chemical fertilizers. Amino ...

Problems solved by technology

[0004] Most of the magnetic fertilizers currently on the market are due to their unreasonable nutrient structure ratio, low compounding, insufficient biological activity, insufficient fertility of magnetic fertilizers, low stability of nutrient residual magnetism, and the mutual promotion advantages of magnetism and fertilizers are not outstanding. , the use effect did not achieve the expected effect

[0005] In the existing agricultural production, chemical fertilizers or organic fertilizers are often used. The former has problems such as low utilization rate, many residues, serious pollution, and diminishing fertilizer efficiency. Long-term application will lead to soil compaction, soil fertility decline, land desertification, and eventually desertification.

However, when the latter organic fertilizer is applied, there are low nutrients, poor quick-acting performance, and low efficiency, so that the crops are defertilized in each stage of vegetative growth and reproductive growth.
