Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cultivating shiitake mushrooms by humus for stably supplying shiitake mushrooms in a quality desired by consumers at a proper time and in a required amount.

[0002]

2. Description of the Related Art Current shiitake cultivation methods are unstable cultivation techniques that cannot be covered by natural cultivation methods that are affected by the weather and cannot absorb the cost of raw wood, medium sterilization equipment and inoculum costs that account for most of the production costs. Is forced to continue.

[0003]

The present invention was made in order to solve the unstable cultivation method by the above-mentioned current technology, and its purpose is to make a good quality wood or cultivation medium. We provide a method for cultivating shiitake mushrooms by humus that can promote the cultivation of institutional horticultural cultivation, as well as the problems that occur in plants, the problem of extending the life of sapwood or cultivation media (including sterilization costs) that account for most of production costs. Especially.

[0004]

The method for cultivating shiitake mushrooms by humus according to the present invention is as listed below.

1. Means to solve various problems that occur when making sapwood or cultivation medium. As a substitute for sterilization of Shiitake mushrooms and improper rotation of bacteria due to insects and other bacteria on the outer surface or material of raw wood or cultivation medium, especially as a sterilization alternative for materials such as wood powder contaminated with various bacteria in the medium, organic complex of enzyme humus is used. Body iron complex solution FM10
Most of them are solved by the sterilizing power of hydrogen peroxide generated by the reaction of the trivalent iron complex (molecular weight of 1000 or more) of 0 with polyphenols of raw wood or wood powder.

However, the above reaction becomes inactive once. On the other hand, the hydroxy radical generated during the condensation reaction of the divalent iron complex (molecular weight of 1000 or more) with the general organic substance at the pH-increasing site has a strong bactericidal power, and thus all the problems are solved. .

[0007] After the inoculation of the Shiitake inoculum, the measures against phytophytic black rot caused by harmful fungi growing on the non-rotating part from the outside and the bactericidal activity of the Shiitake bacterium are reduced with Enzyme humus. Organic complex iron complex (molecular weight 1000 or more)
Solubilizes the pectic substance in the vicinity of the wall of the sapwood, for example, and expands the passage of Shiitake fungi to promote the bacterium rotation and prevent the increase in bacterium density.

In particular, regarding the cultivation medium, when the above FM100 is added to the extracted grounds of wood flour or coffee and exposed to sunlight or ultraviolet rays, photodecomposition is promoted by α-carbonyl as a light absorbing group in FM100, and Shiitake fungi are used. Since the molecular weight is reduced to such a level that it can be decomposed, survival and hyphal elongation are accelerated, and damage by harmful bacteria is prevented.

2. Measures to the problem of extending the life of sapwood or cultivation medium. Not only sugars and low-molecular-weight proteins in the sapwood of sapwood or cultivation medium, but also lignocelluloses, which are involved in maintaining the strength of the wood, are decomposed and inoculated by Shiitake fungi, and decrease year by year. .

In particular, by using FM100, a physiologically active low molecule (molecular weight 100) in the organic complex iron complex is used.
Since the growth promotion of Shiitake fungi by (0 or less) reaches 2-3 times, the consumption of sapwood or cultivation medium is large.

As a nutrient that is easily absorbed by Shiitake fungi from sardines or cultivation medium, a complex having a molecular weight of 1000 or less is extracted as a calcium complex from an organic complex of enzyme humus, which is used as a nutrient carrier at 8%. Use, 2%
The consumption of FM200 containing 1% sucrose and 1% ligninsulfonic acid (conifer) infiltrated into a sapling or a culture medium prevents its consumption.

3. Means for problems that promote institutional horticulture. For the expansion of quality, yield and production scale, please refer to the above FM
Although it is possible to solve the problem by using 100 and 200, it is also difficult to control the absorption rate of the nutritional component at the time of occurrence, which was difficult to do below the temperature stimulation and the adjustment of the water content (water content and oxygen content stimulation). Since it became possible with FM200, it is also possible to adjust the carbon rate and control the organic oxygen to adjust the timing of shiitake outbreak.

Regarding the above-mentioned enzyme humus, neutral humus is made into a low molecular weight by biotechnology, the amount of this is increased, and it is also stabilized. A powder of micellar colloid of an organic compound complex mainly composed of fulvic acid. The pH is adjusted to 2.8 or less, the oxidation potential is adjusted to 200 mV, and the water content is adjusted to 50 to 60%.

The enzyme humus used in the present invention is derived from a neutral humus which has been buried in the ground as a raw material by condensing the leaves of deciduous trees and decomposed products of animal origin in a warm climate. It is made into a powder after it has been reduced to a low molecular weight by, recombined, and stabilized. The pH is 2.6 or less, the oxidation potential is +500 mV or more, and 10% or more of an organic compound complex (corresponding to fulvic acid in the analytical classification) is contained in a stable state as a free and iron complex. The organic compound has a molecular weight of 2000 or more and 100
The average content of 0 to 2000 and 1000 or less is 6:
It is 3: 1.

[0015]

EXAMPLES The present invention will be described below with reference to examples thereof. Quercus logs (diameter 60 mm, felled in late October)
(Length 200 mm) is soaked in FM100 with pH 3.5 for 2 days, drained, seed plucked when outer branches are dry, and then soaked in FM200 for 1 day, and then temporarily laid at 25 ° C. As a result of carrying out each for 2 days and 5 days, the growth of Shiitake fungus was more than 3 times that of the conventional method, and compared to the conventional method where the mycelial colonies were limited to around the seed pieces, 3 days after the temporary disposition, the conduit and temporary conduit In the sieving tube portion and its peripheral portion, the longest diameter was spread to the fullest extent, and on the 5th day of the main felling, white mycelium agglomerates were formed on the entire groove and cut surface (including the heartwood portion) of the outer tree.

In addition, when a shiitake mushroom generation test was conducted by the current method, the generation amount was more than doubled, and the dried product was of the highest quality, and the life of sardine tree was more than doubled. Was confirmed.

[0017]

[Effects of the Invention] Compared to the current cultivation method, the combination of FM100 and FM200 is more than twice the amount of shiitake.
It has been confirmed that the life of sardine wood is more than doubled, and it is expected that the cultivation of shiitake mushrooms will enter a stable management era with the present invention as a result of the possibility of institutional horticulture.
