Problems solved by technology

The disadvantages of the above methods are that direct return to the field requires a large amount of soil nutrients, and it is easy to cause bacteria to multiply, and the spread of diseases will seriously affect the surrounding living environment.
The microbial fermentation process is mainly in the production process, the fermentation period is long (generally 20-50 days), the investment in turning and throwing equipment is large, the production cost is high, the nutrient content is low, and the fertilizer efficiency is slow. In the process of use, it is necessary to cooperate with chemical fertilizers

Abstract

The invention relates to an organic fertilizer prepared from edible fungus slag, a preparation method thereof and an application thereof. The edible fungus slag organic fertilizer comprises, by weight, 45 to 70 parts of edible fungus slag, 5 to 20 parts of weathered coal, 4 to 15 parts of urea, 10 to 15 parts of monoammonium phosphate, 7 to 20 parts of potassium chloride, 1 to 5 parts of a trace element fertilizer, 1 to 5 parts of a chemical degradant, and 5 to 10 parts of a curing agent. The preparation method comprises the following steps: shearing and crushing the edible fungus slag; adding other components and mixing; degrading and solidifying; and obtaining circular particles through extruding to pelletize, and polishing and reshaping. The edible fungus slag organic fertilizer, whichcontains various amino acids, humic acid, nitrogen, phosphor, potassium and trace elements which are required by the growth of crops, allows a humic acid chelate which is formed through a chelation reaction and contains the trace elements which can be easily absorbed by plants to be generated, the utilization rate of the nutrients of the fungus slag organic fertilizer to be improved and the application to be convenient and labor saving, and can be used for industrial crops such as grains, vegetables, fruits and the like.

Description

technical field [0001] The invention relates to a pollution-free organic fertilizer produced by using edible fungus slag and its preparation method and application, belonging to the technical field of solid waste recycling and fertilizer. Background technique [0002] my country is a big producer of edible fungi, with an annual output of about 22 million tons, accounting for more than 70% of the world's total output, and a total output value of more than 60 billion yuan. With the development of the edible fungus industry, a large number of edible fungus residues are produced every year. For every ton of edible fungi produced, 0.6 tons of mushroom residues are produced, which is about 13.2 million tons. The quantity is huge. Edible fungus slag is the culture medium waste left after harvesting products in the cultivation process of edible fungi. The organic matter content of fungus slag is about 35--70%, and the mineral nutrients nitrogen, phosphorus, and potassium required fo...
