Edible fungus residue organic fertilizer raw materials and preparation method thereof

Abstract

The invention relates to edible fungus residue organic fertilizer raw materials and a preparation method thereof and belongs to the field of comprehensive utilization of resources. Vinegar residues are used as a culture medium for cultivating edible fungi; coarse fibers in the vinegar are decomposed by the edible fungi, so the fertilizer efficiency of the vinegar residues is improved; and fungus residues obtained after the edible fungi are cultivated are directly used as the organic fertilizer raw materials. According to the vinegar residues, the content of organic matter is 50 percent, but the content of coarse fibers is above 20 percent; and the vinegar residues is low in fertilizer efficiency and can only be used as a green seedling cultivation substrate or used for improving soil; if microorganism composing fermentation is adopted, a cycle is long; and the cycle of the method is almost the same as that of composing fermentation, but extremely obvious economic benefits are created; and the prepared organic fertilizer raw materials are durable in fertilizer efficiency and pollution-free, and can improve soil and the quality of crops, and promote growth of the crops. An effective way for comprehensively utilizing the vinegar residues is provided.

Description

technical field [0001] The invention relates to an edible fungus residue organic fertilizer raw material and a preparation method thereof, belonging to the technical field of comprehensive resource utilization. Background technique [0002] Vinegar grains are the main leftovers for making vinegar, accounting for about 70% to 80% of the raw materials for making vinegar. The components of vinegar grains are rice husk, bran, rice dregs, etc., with a moisture content of about 70% and a pH value of 4.5-5.5, which is weakly acidic. Vinegar grains contain 6% to 10% of crude protein, 2% to 5% of crude fat, 13% to 17% of crude ash, 14% to 18% of nitrogen-free extract, 0.25% to 0.45% of calcium, and 0.16% to 0.37% of phosphorus , the crude fiber content is as high as 20% or more. [0003] Vinegar grains as feed have poor palatability and low nutritional content, so they cannot be used in large quantities. In addition, due to the high moisture content of vinegar grains, drying requir...

Problems solved by technology

[0006] Today, with the vigorous promotion of circular economy and the development of low-carbon industries, a large amount of untreated vinegar residues are piled up on the spot or directly applied to the farmland every year. This is not only a huge waste of agricultural organic resources, but also It is also easy to cause bacteria to multiply, spread diseases, and affect the surrounding living environment

Moreover, the current sources of organic fertilizer raw materials are limited, and the output of organic fertilizers is far from meeting the needs of agricultural production. Therefore, how to comprehensively utilize vinegar grains to convert them into organic fertilizer raw materials with complete nutrients, long-lasting fertilizer effects and no pollution has become an important issue in the vinegar industry. big problem
