Problems solved by technology

[0005] At present, relevant literature reports on sludge agricultural use have been reported, such as: Chinese patent application CN201110196472.5, which discloses a bio-organic fertilizer produced from municipal sludge and a preparation method thereof, using municipal sludge, quicklime powder, ferrous sulfate , magnesium sulfate, corn stalks, bio-organic fertilizer fermentation agents, lysine, bone meal, etc. to prepare bio-organic fertilizer. The bone meal required for this application comes from schools, enterprises, government canteens and hotels. The source of raw materials is limited, the operation is complicated, and there is no It is difficult to do any treatment of heavy metals in sludge, which is difficult to produce in large-scale chemical plants
[0006] Chinese patent applications CN200910144350.4 (method for producing organic fertilizer using urban sludge) and CN201110199865.1 (a kind of sludge organic fertilizer for forestry greening and its preparation method), the above two applications are the use of sludge, straw, bean cake powder Such as agricultural organic waste and nitrogen, phosphorus and potassium as raw materials to prepare organic fertilizers, it takes a long time and does not do any technical treatment of heavy metals in sludge
[0007] Shrimp and fish processing will produce about 35% to 45% of the leftovers such as heads, shells, feet and viscera. It is estimated that more than 1 million tons of leftovers will be produced every year in my country. Due to the high moisture content of these leftovers, they are easily corrupted and smelly. If it is treated as waste, it will cause serious secondary environmental pollution and waste of resources
[0008] At present, there are no relevant reports on the use of hydrolyzed sludge complexed with aquatic product processing leftovers to produce organic fertilizers. The nutritional value and biological activity of aquatic product processing leftovers are much higher than those of plant organic waste. Solve the problem of bulk organic solid waste treatment in my country, realize high-value utilization of waste resources, and produce high-quality organic fertilizers, which have important practical significance for soil improvement, soil ecological balance and agricultural product safety in my country

Embodiment 1

[0036] Embodiment 1 A kind of special organic fertilizer preparation

[0037] Preparation of compound amino acid hydrolyzate: take 1 ton of fresh shrimp head, crush it, add mixed enzyme and water after sterilizing at 100°C, and make it after 40 hours of constant temperature enzymolysis at 60°C, wherein the weight ratio of raw materials, water and mixed enzyme is : 100:20:0.03. The mixed enzyme is a compound enzyme mainly composed of protease and acid cellulase, and the others are chitinase. Wherein protease and acid cellulase account for more than 90% of the total amount of mixed enzymes, the dosage ratio of protease and acid cellulase is 7:3, and the protease is bromelain.

[0038] Preparation of organic matter: 1440kg of sludge with a moisture content of 65%, mixed evenly with 480kg of peanut bran and 480kg of humic acid, were ventilated and fermented at room temperature for 3 days.

Abstract

The invention relates to the field of fertilizers and provides a special organic fertilizer which comprises the following components in parts by weight: 50-70 parts of organic matter, 20-35 parts of composite amino acid hydrolysate, 2-6 parts of nitrogen fertilizer, 1-3 parts of potash fertilizer and 3-8 parts of phosphate fertilizer. The organic fertilizer is produced by complexing the composite amino acid hydrolysate with sludge, the process flow is reasonable, the operation is simple, the preparation method is suitable for mass production, and a value added is high. The special organic fertilizer is high in activity and rich nutrient, has an effect of efficient soil improvement of an organic fertilizer, can obviously improve disease and insect pest resistance of crops and restore damaged root systems, and can particularly reduce a soil-borne fungal disease and a root knot nematode disease effectively.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special organic fertilizer and a preparation method thereof. Background technique [0002] Organic fertilizers are mainly fermented from animal and plant residues, excrement, and biological waste. They contain essential macroelements, trace elements, and rich organic nutrients. They can effectively cope with and solve soil compaction, barrenness, and Environmental Pollution. According to the national soil census data, the organic matter of my country's soil is only about 1%, and the phenomenon of soil compaction and poor nutrition is serious, and the demand for organic fertilizer is huge. At present, the qualified rate of organic fertilizers on the market in my country is only about 30%, and the development prospects of high-quality organic fertilizers are broad. [0003] At present, the amount of sludge (dry weight) discharged by urban sewage treatment plants in my country exceeds...
