Problems solved by technology

According to statistics, there are only 30,000 tons of waste (bacteria sticks) from planting shiitake mushrooms in this county every year. The pH value (pH value) of these wastes is relatively low, between 4.1 and 5.2, which does not meet the organic fertilizer standard NY525-2012 Table 1 Medium pH (pH value) of 5.5 to 8.5 is required, but it is discarded or burned anywhere, which not only causes waste of resources and energy, but also produces "three wastes", which aggravates the deterioration of the ecological environment

Embodiment 1

[0026] The organic fertilizer of this embodiment is obtained by the following method:

[0027] (1) Drying and dehydration: Take the waste mushroom sticks out of the bag and dry them at 120°C;

[0028] (2) Raw material crushing: crush the dried and dehydrated mushroom sticks to 30 meshes;

[0029] (3) Take the mixed sample of the crushed lentinus edodes fungus sticks to detect its pH value. According to the measured pH value, add an appropriate amount of ammonium bicarbonate to the crushed lentinus edodes fungus sticks to make the pH value 6.5;

[0030] (4) Mixing of raw materials: uniformly mix the crushed shiitake mushroom waste fungus sticks and the straw decomposing agent to obtain a mixture. The crushed shiitake mushroom waste fungus sticks in the mixture account for 98wt%, and the straw decomposing agent accounts for 2wt%;

[0031] (5) Composting fermentation: pile up the above mixture into a strip-shaped fermentation pile with a bottom width of 2 meters and a height of about 1 met...

Embodiment 2

[0037] The organic fertilizer of this embodiment is obtained by the following method:

[0038] (1) Drying and dehydration: Take the waste mushroom sticks out of the bag and dry them at 100°C;

[0039] (2) Raw material crushing: crush the dried and dehydrated mushroom sticks to 20 mesh;

[0040] (3) Take the mixed sample of the crushed lentinus edodes fungus sticks to test its pH value. According to the measured pH value, add an appropriate amount of powdered calcium hydroxide to the crushed lentinus edodes fungus sticks to make the pH value 8.5 ;

[0041] (4) Mixing of raw materials: uniformly mix the crushed shiitake mushroom waste fungus sticks and the straw decomposing agent to obtain a mixture. The crushed shiitake mushroom waste fungus sticks in the mixture account for 98.5 wt%, and the straw decomposing agent accounts for 1.5 wt%;

[0042] (5) Composting fermentation: pile the above mixture into a strip-shaped fermentation pile with a bottom width of 2.5 meters and a height of ab...

Embodiment 3

[0048] The organic fertilizer of this embodiment is obtained by the following method:

[0049] (1) Drying and dehydration: Take the waste mushroom sticks out of the bag and dry them at 115°C;

[0050] (2) Raw material crushing: crush the dried and dehydrated mushroom sticks to 25 mesh;

[0051] (3) Take the mixed sample of the pulverized waste mushroom sticks to test its pH value. According to the measured pH value, add an appropriate amount of ammonium bicarbonate and powdered calcium hydroxide mixture to the pulverized waste mushroom sticks ( The mass ratio is 1:1), so that its pH value is 5.5;

[0052] (4) Mixing of raw materials: uniformly mix the crushed shiitake mushroom waste fungus sticks and the straw decomposing agent to obtain a mixture. The crushed shiitake mushroom waste fungus sticks in the mixture account for 99wt% and the straw decomposing agent accounts for 1wt%;

[0053] (5) Composting fermentation: pile up the above mixture into a strip-shaped fermentation pile with ...

Abstract

The invention discloses a mushroom planting waste culture medium produced organic fertilizer. A preparation method of the mushroom planting waste culture medium produced organic fertilizer comprises the steps sequentially including, debagging, drying and then crushing mushroom planting waste culture mediums; adding in an appropriate amount of ammonium hydrogen carbonate or powder calcium hydroxideor a mixture of the ammonium hydrogen carbonate and the powder calcium hydroxide, and regulating the pH to 5.5-8.5; proportionally and uniformly mixing the crushed mushroom planting waste culture medium and straw decomposing agent to obtain a mixed material; stacking the mixed material into bars for decomposition, covering the stacked mixed material with plastic films, increasing the stacked mixed material to 60-70 DEG C for continuous fermentation for 7-15 days; uniformly mixing bentonite into the fermented materials, and then performing pelletizing to obtain fertilizer pellets; drying the fertilizer pellets into a drying cylinder to obtain dried fertilizer pellets; cooling the dried fertilizer pellets inside a cooling cylinder to obtain cooled fertilizer pellets; performing grain size screening on the cooled fertilizer pellets to obtain the finished organic fertilizer.

Description

Technical field [0001] The invention relates to the technical field of reuse of waste mushroom sticks of shiitake mushrooms, in particular to an organic fertilizer using waste mushroom sticks for planting shiitake mushrooms and a preparation method thereof. Background technique [0002] In recent years, following the rapid rise of the traditional fungus industry in various parts of our region, the large amount of waste fungus sticks (slag) after planting mushrooms has become more and more harmful to the ecological environment and the planting industry itself. If the discarded mushroom sticks are thrown away directly, it will not only pollute the environment, but also waste resources for the production enterprises. The waste culture material (mycobacteria) after the cultivation of lentinus edodes contains the mycelium residue of the lentinus edodes and the crude fiber compound whose structure has changed after the hyphae digestion. The organic matter content and nutritional value ...
