Embodiment 1

[0016] Organic fertilizer: 50 kg of humic acid, 50 kg of raw chicken manure, 1.5 kg of compound bacterial agent and 500 kg of bacterial chaff are mixed and fermented to become bio-organic fertilizer.

[0017] The sources of the above materials are:

[0018] The compound bacteria agent is produced by Shenyang Lvyuan Biotechnology Research Institute, and its trade name is organic material decomposing agent. The technical index of strains is that the number of effective viable bacteria (each quantity) is 0.01 billion / g; the water content is ≤35%; the miscellaneous bacteria rate is ≤30%;

[0019] Humic acid HA contains more than 40% of total humic acid, derived from lignite (weathered coal), ph value <7.0.

[0020] Chicken manure is raw chicken manure. It contains about 25.00%-27.00% of crude protein, 1.40% of crude fat, 26.60% of nitrogen-free extract, 12.70% of crude fiber, 27.09% of crude ash, and a large amount of trace elements.

[0021] Mushroom bran comes from the produc...

Embodiment 2

[0045] Organic fertilizer: 40 kg of humic acid, 40 kg of raw chicken manure, 1.5 kg of compound bacterial agent and 500 kg of bacterial chaff are mixed and fermented to become bio-organic fertilizer.

[0046] Preparation: Mix 540 kg of humic acid, 40 kg of raw chicken manure, 1.5 kg of compound bacterial agent and 500 kg of bacterial chaff, stir evenly after mixing, adjust the water content to about 50%, C:N=20-30:1; When the temperature rises above 50°C, it is overturned, ventilated and fermented for 5-7 days, and the bio-organic fertilizer is obtained.

[0047] application:

[0048] The above materials are applied to 1 mu of land to plant Chinese cabbage, and the yield increases by 8.4% compared with that of the control group (1000 kg of fungus chaff per mu).

Embodiment 3

[0050] Organic fertilizer: bacteria chaff, humic acid, raw chicken manure and compound bacterial agent in parts by weight of 1:0.08:0.1:1 / 300, mixed and fermented to become bio-organic fertilizer.

[0051] Preparation: Mix fungus bran, humic acid, raw chicken manure and compound bacterial agent in parts by weight 1:0.08:0.1:1 / 300, stir evenly after mixing, adjust water content to about 50%, C:N=20- 30:1; overturn when the temperature rises above 50°C, ventilate and ferment for 5-7 days to obtain bio-organic fertilizer.

Abstract

The invention relates to a biological organic fertilizer, and particularly relates to a biological organic fertilizer prepared by using mushroom bran as a raw material and a preparation method thereof. The biological organic fertilizer is prepared by mixing mushroom bran, humic acid, raw chicken manure and a composite bacterial agent according to weight parts, and performing fermentation. On a weight basis, the ratio of the mushroom bran, humic acid, raw chicken manure and the composite bacterial agent is 1:0.08-0.1:0.08-0.1:1 / 300-1 / 400. The fertilizer of the invention can eliminate biological pollution of the mushroom bran; nutrient substances of the mushroom bran are made full use of for the production of the fertilizer; no harm is caused to the environment; and the reutilization of resources is realized.

Description

technical field [0001] The invention relates to a bio-organic fertilizer, in particular to a bio-organic fertilizer made of fungus chaff as a raw material and a preparation method thereof. Background technique [0002] Mushroom bran refers to the waste residue after cultivating edible fungi with cottonseed hulls, sawdust, straw, corncobs, various crop straws, industrial waste (distiller's grains, etc.) as the main raw materials, although it contains a large amount of crude fiber, lignin and mycelium body (rich in protein, amino acids, carbohydrates, vitamins and trace elements), but because a large part of the fungus chaff is not processed in time after the cultivation of edible fungi, the types and quantities of miscellaneous bacteria will be geometric in a short period of time. The number of stages increases, and the metabolites of these bacteria not only cause high furo acidity, but also some toxins in the metabolites, which not only pollute the agricultural ecological en...
