Abstract

The invention discloses a method for producing pleurotus ostreatus by utilizing biogas residue. The method comprises the steps of stacking biogas residue which is thoroughly fermented and decomposed and has no excrement odor in a higher place, dripping moisture of the biogas residue, ensuring that the moisture content of the biogas residue is between 60 and 70 percent, preparing culture solution by mixing the treated biogas residue and cotton seed hull filler well according to the weight ratio of 3:2, and performing fermentation for fruiting according to the prior method for producing pleurotus ostreatus. The method utilizes biogas residue to cultivate pleurotus ostreatus, and has the advantages of extensive and convenient draw materials, simple technique and low cost.

Description

Utilize the natural pond slag to produce the method for flat mushroom

Technical field

The present invention relates to produce the method for flat mushroom, especially utilize the natural pond slag to produce the method for flat mushroom.

Background technology

The most cotton seed hullss that use of flat mushroom production cultivation material along with the rise of cotton seed hulls price, have influenced the raising of flat mushroom productivity effect.The natural pond slag is as the byproduct of producing biogas, traditionally just the application of natural pond slag as fertilizer sources, and utilizes and badly also can cause secondary pollution, contains multiple nutritional components in the slag of natural pond, and is close with the mushroom cultivation material nutrient content, the very growth of edibility bacterium.

Summary of the invention

The technical problem that the present invention solves provides a kind of lower-cost method of utilizing the natural pond slag to produce flat mushroom.

For addressing the above problem, the inventive method step is as follows:

(1) processing of natural pond slag

Select for use natural pond slag muck through abundant fermentation maturity, no excrement stink to be placed on the higher local drop of the physical features part of anhydrating, making its moisture content is 60%-70%.

(2) culture material preparation

Natural pond slag after handling and cotton seed hulls stopping composition mixed thoroughly with the part by weight of 3:2 promptly make nutrient solution.

(3) according to the existing flat mushroom production method fruiting that ferments

Advantage of the present invention is: the natural pond slag contains organic substance 30%-50%, humic acid 10%-20%, crude protein 5%-9%, full nitrogen 1%-2%, full phosphorus 0.4%-0.6%, full potassium 0.6%-1.2% and several kinds of mineral elements, close with the mushroom cultivation material nutrient content, and assorted bacterium is few, be fit to very much the growth of flat mushroom, flat mushroom is that a kind of vitality is strong, and adaptability is strong, the edible mushrooms that output is high, utilize natural pond slag for cultivating flat mushroom to have to draw materials extensively, convenient, technology is simple, saving of work and time material-saving, cost are low, quality better, output height, advantage such as profitable.

Embodiment

Further specify technical scheme of the present invention below in conjunction with specific embodiment.

(1) processing of natural pond slag is selected for use through abundant fermentation maturity, and normal gas producing is more than 3 months, and the natural pond slag of no excrement stink after it is taken out, is deposited in the higher local draining of physical features 24 hours from methane-generating pit, just can make culture material when its moisture content is 60%-70% and use.Note not salvaging sediment at the bottom of the pond, in order to avoid bring not dead parasitic ovum into.In the draining process, cover plastics film, preventing that the fly worm from laying eggs pollutes the mushroom bed.

(2) preparation of culture material

Because the natural pond slag is the residue through long-term anaerobically fermenting, mostly becomes unsetting state, air permeability is poor.Therefore, make culture material, need to add cotton seed hulls and make weighting material,, help airiness, satisfy the needs that mycelial growth is grown to increase the space of bed material with the natural pond slag.The ratio of natural pond slag and stopping composition is advisable with 3:2.Stopping composition adds an amount of water earlier mix thoroughly after, again with draining after the natural pond slag mix and stir and can go to bed.If make stopping composition with cotton seed hulls, must not have and go mouldy, want airing before the use.

(3) the selection flat mushroom of mushroom bed is at mattress silk growth phase, and optimum temperuture is 25～27 ℃, and relative air humidity is 70%, and in the long mushroom stage, optimum temperuture is 12～18 ℃, and culture material surface moisture and relative air humidity are about 90%.Flat mushroom is less demanding to light, has scattered light to get final product.The general airy of selecting in mushroom bed ground is indoor.If the mushroom bed is located at ground upstairs, need to preserve moisture with plastics film is rebasing.The mushroom bed surface is wide 0.8～1.0 meter, length visual field ground and decide 6.5～8 centimetres of the thickness of culture material.

(4) grasp flat mushroom incubation time in sowing time is late September to the second at year first the end of month, all can sow within these 120 days.4 kilograms of every double centner culture material program request bacterial classifications.Bacterial classification requires mycelia plentiful, does not have assorted bacterium, and cell age preferably is no more than 1 month.6.5 centimeter square program requests are pressed in sowing, 3.3 centimetres of the program request degree of depth, and one of every cave point broad bean size is broadcast the back and is covered with plastics film, to be incubated, to preserve moisture.

(5) the mycelial growth stage of daily administration flat mushroom is the stage of accumulation nutrient, and moisture and oxygen demand are little.Therefore, need to build, with moisture-heat preservation with prevent living contaminants with film.Generally took off the film ventilation once every 7 days.After sporophore formed, water requirement and oxygen requirement increased, and at this moment will note ventilating and keeping the skin wet.When the bacterium pearl begins to occur, bacterium bed surface wettability when a large amount of vaporize water is arranged in the film, should be propped ventilation with film.Ventilate the back as bacterium bed surface drying, the management of can spraying water.When the principle of water spray is dry weather, diligent spray, few spray, the rainy day does not spray.

(6) timely collecting

Under optimum conditions,, need approximately through about 7 days to growing up to sporophore (edible part) from fruiting, sporophore is long can gather to medium well.Gather and want to influence output too early, after influencing quality late in good time.After first is gathered, through 15～20 days next batchs of can gathering again.After the culture material inoculation, 3～4 batches of flat mushrooms of generally can gathering.

(7) impose nutritive medium

Need impose nutritive medium behind the results-stubble flat mushroom, early send out high yield to promote following batch flat mushroom.The method that imposes is: make a call to 2 centimetres of dark holes with wooden stick on the culture material surface, urea soln with 0.1% or 0.1% urea soln add 0.1% syrup perfusion.

(8) control of disease and pest

Under hot and humid condition, culture material is infested easily, and long assorted bacterium is found varied bacteria growing, should in time dig only, finds insect pest, available 0.2%～0.3% SD-1750 spraying or with SD-1750 cotton balls smoked kill, but to note preventing poisoning.

Claims (1)

1, a kind of method of utilizing the natural pond slag to produce flat mushroom is characterized in that method steps is as follows:

The first step: the processing of natural pond slag

Select for use natural pond slag muck through abundant fermentation maturity, no excrement stink to be placed on the higher local drop of the physical features part of anhydrating, making its moisture content is 60%-70%;

Second step: culture material preparation

Natural pond slag after handling and cotton seed hulls stopping composition mixed thoroughly with the part by weight of 3:2 promptly make nutrient solution.

The 3rd step: according to the existing flat mushroom production method fruiting that ferments.
