Abstract

The invention relates to a technology for producing a high-quality straw rotting edible mushroom concentration culture medium by using detoxification blue-green algae dry powder and super absorbent resin to serve as main raw materials and belongs to the technical field of agricultural production. The method can be applied to production of a wood-destroying fungi culture medium. The method comprises the following steps of conducting ozone detoxification and dehydration processing, adding constant salt matters (the dray powder adding amount is 90%), mixing the constant salt matters with 10% of super absorbent resin at the water absorbing rate of 100 times, adding 80%-90% of straws or crop straw materials, and replacing the traditional edible mushroom culture medium. Effects of increasing 10-15% of the production are achieved on the basis of reducing compost raw material cost by more than 50%. The method solves the problem that the blue-green algae environmental pollution is serious and the like at present, turns waste into wealth and is high in social and economic benefits.

Description

A kind of take detoxification blue-green algae dry powder and super absorbent resin as the main material production high-quality method of the rotten edible mushroom enrichment medium of grass

Technical field

This patent is a kind of technology of using bacterium culture medium for production high-quality grass saprophage in field of agricultural production technologies.Belong to the technical field of edible fungi production in agrotechnique.

Background technology

The rotten edible mushroom of grass refers to absorb organic matter in the rotten grass such as dogstail stalk (as straw, wheat straw) as the mushroom in Major Nutrient source, the required cultivation primary raw material of straw rotting fungus is crops straw, and grass tree section stalk, straw rotting fungus produces itself need not to consume forest tree resource.

The straw rotting fungus class mainly contains agaricus bisporus, high temperature mushroom, brown mushroom, Ji Songrong, straw mushroom and coprinus comatus etc.Picture Pleuotus nebrodensis Quel, Xingbao mushroom, straw mushroom, two spore mushroom, coprinus comatus etc. belong to the straw rotting fungus class.

The rotten edible mushroom enrichment medium of grass refers to that be 10%-20% at the careless saprophage of routine with the adding proportion in bacterium culture medium, contains the medium of the required macroelement of careless rotten edible mushroom and trace element.

Blue-green algae is prokaryotes, cries again the blue-green alge cyanobacteria; The colloid clothing is arranged outside the cell wall of most of blue-green algaes, therefore be again Myxophyceae.In all algae bios, blue-green algae is simple, the most original a kind of.Blue-green algae is unicellular organism, there is no cell nucleus, but nuclear matter is contained in cell central authorities, usually is graininess or netted, and chromatin and pigment are evenly distributed in cytoplasm.This nuclear matter does not have nuclear membrane and kernel, but has the function of core, therefore be called protokaryon (or nucleoid).Also have a kind of cyclic DNA---plasmid in blue-green algae, taken on the effect of carrier in gene engineering.The same with bacterium, blue-green algae belongs to " prokaryotes ".The blue-green algae nutritive value is abundant, ether acid blue algae is example, obtain it through check and contain protein (40%), mainly by isoleucine (isoleucine), leucine (leucine), lysine (lysine), methionine (methionine), phenyl alanine (phenylalanine), threonine (threonine), tryptophan (tryptophane), the compositions such as valine (valine).In addition, also fatty (content is at 4%-4.5%), carbohydrate (16%-17%), chlorophyll, carotenoid, phycocyanobilin, vitamin (vitamin) A, B1.B2.B6.B12.E, nicotinic acid (nicotinic acid), creatine (creatine), gamma-Linolenic acid (γ-linolenic acid), calcium pantothenate, folic acid (folic acid) and calcium, iron, zinc, magnesium etc.

But simultaneously because the microcystis kutz in blue-green algae contains Microcystin (MC.), the class ring-type seven peptide hepatotoxin that Anabaena, Oscillatoria and Nostoc produce, can be by the activity of Profilin phosphatase, the acute poisoning that causes domestic animal and the mankind, the blue-green algae of therefore using in the composts or fertilisers of cultivating production process at first must be through detoxification treatment.Through the blue-green algae after detoxification treatment, its nutrient component will be considerably beyond the nitrogenous source animal wastes commonly used of the rotten edible mushroom of current grass, and through after high temperature treatment, living contaminants and damage by disease and insect greatly reduce.

Super absorbent resin is a kind of novel macromolecular material, polyacrylic acid sodium salt SUPER-ABSORBENT POLYMER, and it can absorb the moisture of own wt hundred times to thousand times, and is nontoxic, harmless, pollution-free; The water absorbing capacity extra-heavy, the water retention capacity extra-high-speed, the heavy polymer that obtains by acroleic acid polymerization → high moisture-holding capacity, the balance of absorptive amount under high load capacity, absorb water and minute can not be extruded by simple physical method, and can repeatedly release water, suction.

Summary of the invention

The present technique main contents are take dehydration, the pretreated blue-green algae dry powder of detoxification, super absorbent resin as primary raw material, the nutrition required according to straw rotting fungus after mixing with certain proportion, add multiple constant and micronutrient element, production can use with careless saprophytic product field in the high-quality edible mushroom enrichment medium, at the materials such as rice straw that add 80%-90%%, substitute traditional careless saprophage bacterium culture medium, on the basis that reduces culture medium raw material cost 10%, reach the effect of volume increase 20%.Turn waste into wealth thereby reach, increase social and economic benefits, the purpose of environmental contamination reduction.

For example: after the dehydration of blue-green algae process, detoxification treatment, after the super absorbent resin of 100 1 hundred times of water absorption rates mixes with the ratio of 4: 1, add the salts substances such as gypsum, potassium dihydrogen phosphate, magnesium sulfate, made careless rotten edible mushroom concentrates composts or fertilisers of cultivating, is used for Lentnus edodes, and adding proportion is 10-20%% in composts or fertilisers of cultivating, and add 80%-90% straw or agricultural crop straw, its cost of material reduces by 20%, and incubation time reduces 10%, and output increases 10%-15%.

Embodiment

The concrete implementation and operation step of present technique is as follows:

The preparation of blue-green algae dry powder

With the fresh blue algae mud of salvaging, be positioned in fermentation tank, the ozone that passes into 50% concentration carries out detoxification treatment, and the processing ratio is 0.5kg ozone/1 ton fresh algae mud, processing time is about 15min, and termination flag is that Microcystin (MC.) is reduced to＜0.8 μ g/L.

Blue algae mud after detoxification treatment reduces moisture to 70% through belt filter press dehydration pretreatment with it.

To smash through the pretreated blue-green algae mud cake of detoxification dehydration, and adopt the mode of steam drying that its moisture is reduced to below 15% through airing or roller dryer.

The configuration of concentrated composts or fertilisers of cultivating

1. with blue-green algae dry powder after pretreatment, and required according to the growth of the rotten edible mushroom of wood, add gypsum 8%, potassium dihydrogen phosphate 10%, superphosphate 10%, magnesium sulfate 2%, urea 10%.
