Synergist for edible fungus culture medium and preparation and use method thereof

Abstract

The invention relates to a synergist special for edible fungus and a preparation and use method thereof. The synergist special for the edible fungus comprises the following compositions by weight portion: 40 to 70 portions of treated fowl manure, 10 to 25 portions of calcareous shale, 5 to 35 portions of wheat bran and 5 to 10 portions of lime. The method comprises: adding 5 to 30 percent of pine needles and 0.1 to 0.5 percent of fermenting agent for deodorization according to the weight of dry fowl manure; adding water and uniformly mixing manure materials to control the water content of the manure materials to be between 55 and 65 percent, and performing stacking fermentation for 15 to 25 days at natural temperature; drying fermented fowl manure until the water content is less than 20 percent; and uniformly mixing the four compositions to synthesize the synergist. The amount of the synergist accounts for 10 to 30 percent of the weight of edible fungus cultivated materials, and the water content of the cultivated materials is between 55 and 60 percent. The synergist not only reduces the production cost and improves the yield of edible fungus but also reduces environmental pollution of the fowl manure, is favorable for normal growth and metabolism of hypha or fruiting bodies, has no toxicity, harm and potential accumulated toxicity on human beings and animals, and can be widely used for cultivating edible fungus such as oyster mushrooms, yellow oyster mushrooms, chicken leg mushrooms and branched oyster mushrooms.

Description

technical field [0001] The invention belongs to the field of compost for cultivating edible fungi, in particular to a special synergist for the compost of edible fungus and its preparation and use method. Background technique [0002] At present, edible fungi such as Pleurotus ostreatus, Pleurotus chinensis, Coprinus comatus and Pleurotus edodes are mainly composed of cottonseed hulls, corn cobs, sawdust, straw, wheat bran and other materials, with a carbon-to-nitrogen ratio of 30-40:1. It is mainly carbon, nitrogen and trace elements. The carbon source mainly comes from cottonseed hulls, corncobs, wood chips and other materials. The nitrogen source mainly comes from wheat bran, various grain rice bran, etc. Due to the relatively high price of wheat bran, the production cost of edible fungi It is greatly improved, and it is difficult to store wheat bran. In high temperature season, it is easy to be wormed and deteriorated. Contents of the invention [0003] The object of ...

Problems solved by technology

[0002] At present, edible fungi such as Pleurotus ostreatus, Pleurotus chinensis, Coprinus comatus and Pleurotus edodes are mainly composed of cottonseed hulls, corn cobs, sawdust, straw, wheat bran and other materials, with a carbon-to-nitrogen ratio of 30-40:1. It is mainly carbon, nitrogen and trace elements. The carbon source mainly comes from cottonseed hulls, corncobs, wood chips and other materials. The nitrogen source mainly comes from wheat bran, various grain rice bran, etc. Due to the relatively high price of wheat bran, the production cost of edible fungi It is greatly improved, and it is difficult to store wheat bran. In high temperature seasons, it is easy to grow insects and deteriorate. It will become sticky when exposed to water, which will affect the air permeability of the cultivation material. A large amount of use will easily cause pollution of the cultivation material and eventually lead to a reduction in production.
