Lentinus edodes organic fertilizer and preparation method thereof

Abstract

The invention discloses lentinus edodes organic fertilizer and a preparation method thereof. The lentinus edodes organic fertilizer comprises the following fermented materials in percentage by weight: 65-75% of mushroom dregs, 10-20% of cow dung or chicken manure, 5-10% of calcium superphosphate, 1%-5% of urea, 1%-5% of land plaster, 0.5-3% of decomposition agent, 0.5-5% of bran and 0.5-3% of starch. The mixed fermented materials are composted to form a pile and are timely turned according to the variation of internal temperature of the material pile; during pile turning, the external fermented materials are turned to the interior of the pile, and the internal fermented materials are turned to the exterior of the pile; and the appearance of the fermented materials is observed, and when the fermented materials turn from tawny to black brown, become soft and are free of foul smell and musty taste, fermentation is ended. The organic fertilizer produced by using the mushroom dregs makes full use of multiple mineral substances in the mushroom dregs, contains elements such as N, P and K required for crop production as well as microbial flora beneficial to crop growth, has a very good improvement effect for soil and is suitable for plantation of fruit, vegetables, nursery stocks and other crops.

Description

technical field [0001] The invention relates to the field of microbial fermentation, in particular to a method for producing organic fertilizers by fermenting waste fungus residues cultivated by edible fungi. Background technique [0002] my country is a big country in the production and export of edible fungi. In 2014, the total output of edible fungi in the country was nearly 30 million tons, of which shiitake mushrooms accounted for about 18 million tons, and the resulting shiitake mushroom waste residue was as high as 12.6 million tons. The main component of the waste fungus residue after shiitake mushrooms is the plant residue after being utilized by the mushroom hyphae, which is extremely difficult to degrade. In the vast rural areas where shiitake mushrooms are mainly produced, some are used to dry and then burned, and some are discarded at will, causing environmental pollution. Some manufacturers or farmers crush the waste fungus material and use it to grow vegetabl...

In the vast rural areas where shiitake mushrooms are mainly produced, some are used to dry and then burned, and some are discarded at will, causing environmental pollution

Some manufacturers or farmers crush the waste fungus material and use it to grow vegetables, but because the waste fungus sticks contain pathogenic fungi and insect eggs, the nutrients cannot meet the needs of plant growth, resulting in the inability to use them on a large scale.
