Synergist for edible fungus culture medium and preparation thereof and using method
Technical field
The invention belongs to culturing edible fungus and use the composts or fertilisers of cultivating field, particularly relate to a kind of special synergistic agent and the preparation and the using method of composts or fertilisers of cultivating mushroom.
Background technology
Present edible mushroom such as flat mushroom, the yellow mushroom of elm, coprinus comatus, elegant precious mushroom class plant formulation is mainly with cotton seed hulls, corncob, wood chip, stalk, materials such as wheat bran are formed, C/N ratio is 30-40: 1, it mainly is carbon and nitrogen and trace element that nutrition constitutes, carbon source is mainly from cotton seed hulls, corncob, materials such as wood chip, nitrogenous source mainly comes from wheat bran, all kinds of cereal rice brans etc., because the price comparison height of wheat bran, the Edible Fungi cost is improved greatly, and wheat bran storage difficulty, high temperature season is infested easily rotten, becomes sticky behind the chance water, influences the gas permeability of cultivate material, a large amount of uses cause the pollution of cultivate material easily, finally cause the underproduction.
Summary of the invention
The objective of the invention is the problem at above-mentioned culture medium of edible fungus conventional formulation existence, a kind of antipollution is provided, cost is low, impels the special synergistic agent of edible mushroom high yield and the preparation and the using method of this synergist.Synergist of the present invention can be widely used in the cultivation of class edible mushrooms such as the yellow mushroom of flat mushroom, elm, coprinus comatus, elegant precious mushroom, and it is used for producing edible mushroom that the use of this material can make full use of the nutrition of animal dung, can reduce the pollution of animal dung to environment simultaneously.
It is used for producing edible mushroom that the present invention removes the nitrogen nutrition that makes full use of animal dung, also utilize calcareous page or leaf salt to meet the characteristics that expand behind the water, the gas permeability of cultivate material is increased greatly, hypha of edible fungus can growth rate be accelerated under the condition of aerobic, bacterial classification is with the obvious advantage, thereby reduce the pollution in the mycelial growth process, calcareous shale also provides edible fungi growth necessary calcareous element simultaneously.Pine needle contains various trace elements, has nutrition that increases synergist and the effect of removing the animal dung peculiar smell.The use of this synergist can make cultivate material both reach and reduce production costs, and improves edible mushroom output, can reach the purpose of environment purification again.
The synergist for edible fungus culture medium that the present invention is prepared, the parts by weight of contained component and each component are:
The animal dung 40-70 of fermentation process
Calcareous shale 10-25
Wheat bran 5-35
Lime 5-10
The described lime of above-mentioned synergist is white lime, and wheat bran can replace with corn flour, the various rice bran that nothing is gone mouldy.
The preparation method of synergist for edible fungus culture medium of the present invention may further comprise the steps:
1) the deodorizing fermentation process of animal dung: by argol weight the be mixed pine needle of 5-30% weight and the fermenting agent of 0.1-0.5%, adding water puddles and makes moisture be controlled at 55-65%, mix thoroughly, under natural temperature fermentation reactor system 15-25 days, every turning in 8-10 days, be dried to water content and pulverize standby below 20% during this time;
2) calcareous shale is pulverized: it is standby that calcareous shale is ground into the 0.3-0.6cm particle;
3) synergist preparation: by above-mentioned weight proportion animal dung material, calcareous shale, wheat bran and the lime compound of fermentation process cooperated to form synergist for edible fungus culture medium.
The using method of synergist for edible fungus culture medium of the present invention is as follows:
The usage amount of edible mushroom special synergistic agent accounts for the 10-30% of composts or fertilisers of cultivating mushroom weight, and the wet weight in the composts or fertilisers of cultivating is controlled at 55-60%.
The use of synergist of the present invention can make cultivate material both reach and reduce production costs, and improves edible mushroom output, can reach again to reduce the purpose of animal dung environmental pollution with environment purification; The nutrition that the use of these raw materials can make full use of animal dung is used for producing edible mushroom, uses this synergist to be of value to the normal growth and the metabolism of mycelia or fruit body, to nontoxic, harmless, the no potential accumulation toxicity of people and animals; The present invention mixes use as auxiliary material in proportion with the cultivation major ingredient, can be widely used in the cultivation of class edible mushrooms such as flat mushroom, Ji mushroom, coprinus comatus, elegant precious mushroom.
Embodiment
Embodiment 1: the preparation of synergist for edible fungus culture medium
1) the deodorizing fermentation process of animal dung: by argol weight the be mixed pine needle of 5-30% weight and the fermenting agent of 0.1-0.5%, add water and puddle and make moisture at 55-60%, pinch agglomeratingly with hand, openhanded group looses and is advisable; Spread out then, mix thoroughly, build the wide 0.8m of heap, high 1.5m, the long stockpile of not limitting ferments, under natural temperature fermentation reactor system 15-25 days, winter, fermentation time was 20-25 days, 15-20 days all the other seasons, during every 8-10 days, turning once was dried to water content and pulverizes standby below 20% when temperature reached 50-60 ℃;
2) calcareous shale is pulverized: it is standby that calcareous shale is ground into the 0.3-0.6cm particle;
3) synergist preparation: animal dung material, calcareous shale, wheat bran and the cooperation of white lime compound of above-mentioned fermentation process are formed synergist for edible fungus culture medium.
Each amounts of components of above-mentioned four kinds of components preparation synergist sees Table 1.

Embodiment 2: the using method of synergist for edible fungus culture medium
The preparation of culture medium of edible fungus (weight %): corncob 78%, gypsum 1%, sugar 1%, lime 1%, superphosphate 1%, the synergist 20% that 1-5 number is filled a prescription arbitrarily among the embodiment 1; Raw material is mixed according to the above ratio, add a certain amount of water, make water content reach 55-60%, mix thoroughly, be sub-packed in the polyethylene cultivation bag, with the bag compacting, about 3 kilograms of every packed wet feeds, high pressure 1.5atm, sterilization 90min or normal-pressure sterilization 10h, take out the sterilization back, in being cooled to below 30 ℃ under the natural temperature.Under aseptic condition, inoculate in the yellow mushroom of flat mushroom, elm, coprinus comatus, the elegant precious mushroom any one, under 20-25 ℃ of condition, cultivated 30-45 days.Observe mycelium germination and material feeding situation, the dense white degree of mycelia, pollution rate, the calculation biology conversion ratio.The biology conversion ratio of flat mushroom, the yellow mushroom of elm, coprinus comatus, elegant precious mushroom is as follows:
