Abstract

PURPOSE:To promote growth of mushrooms and contrive yield increase and shortening of cultivation period by applying a voltage to bed logs or artificial culture media for mushrooms. CONSTITUTION:Many bed logs 5 or artificial culture media are vertically placed side by side in a container 6 containing water to a depth of several cm and the top is covered with an electrically conductive seal 10 and a wire net 9. A stimulation voltage application means consisting of a voltage regulator, transformer, rectifier and steep voltage generator is provided in a space between the wire net 9 and downward water 7. A stimulation voltage at 1mum-1ms duration of wave front and several kV - some tens of kV wave front value is applied to the bed logs or artificial culture media many times before germination of the mushrooms to increase yield of the mushrooms. If the voltage is applied each time just before germination, cultivation period is shortened.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention promotes mushroom development by applying electrical stimulation to a culture in which inoculated mushroom hyphae have grown,
The present invention relates to a mushroom cultivation method and apparatus suitable for increasing yield and shortening the cultivation period.

[Conventional technology]

In the conventional method of cultivating shiitake mushrooms, sawtooth oaks and Quercus oaks that are felled from October to November are cut into approximately 90cm pieces.
Plant the seed fungus in March to April with Nekaze for about 6 months, leave it in a shed or greenhouse for about 6 months to 1 year while the fungus propagates throughout the tree, and when it is fully ripened, put the tree in an aquarium for about 1 day and night. Submerge in water. During the drying process, the mushrooms germinate and can be harvested.

After harvesting, let the tree rest for about 20 to 30 days, then submerge it in water again.
This cycle of germination, harvesting, and ripening is repeated several times.

The amount of mushrooms harvested over the life of a hodagi is approximately 10% of the weight of hodagi, and currently this amount is harvested several times. That is, -2oog to 30 per session
0g is harvested, and when it reaches 100g or less, it is often stopped.

- If we can increase the amount of mushrooms harvested each time and reduce the number of times they are harvested, the turnover rate of mushroom production will increase and this will lead to increased profits.
Alternatively, the remaining 9 hours of labor can be allocated elsewhere.

[Problem to be solved by the invention]

With conventional mushroom cultivation methods, there is a limit to the amount of mushrooms that can be harvested over the life of a hodagi, and even if electric stimulation is applied to the hodagi as a means of increasing the harvest each time,
If this stimulus was applied to each tree, there was a problem in that the amount of work and time required to move the hodaki would be enormous.

The purpose of the present invention is to increase the yield of mushrooms from Hodagi each time, thereby shortening the cultivation period and increasing profits. An object of the present invention is to provide a method and device for cultivating mushrooms that apply a stimulation voltage to trees.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the method for cultivating mushrooms according to the present invention provides a method for cultivating mushrooms in which the wave crest length is 1 μs to 1 ms and A voltage having a value of several kilovolts to several kilovolts is applied many times, and the stimulation voltage is applied each time before one germination.

The mushroom cultivation device consists of a container filled with water, a large number of which are placed vertically in rows, and a conductive seal and a wire mesh placed on top of the trees or which are artificially grown. It is arranged to provide applying means for applying a stimulation voltage between the wire mesh and the water below.

[Effect]

According to the present invention, with the mushroom cultivation method and device, a stimulation voltage is applied every time to the hodagi just before flooding, that is, to the hodagi just before germination, thereby stimulating the mycelium and quickly producing the total amount of mushrooms. Kusu.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 to 3.

As shown in Figure 1, the wavefront length TF is
A voltage V with a wavefront value VF of several kV to several tens of kV in μS to 1 ms
Apply several times to several times. This stimulating voltage V
The timing of application is to apply to the tree or artificial medium after the mycelia have fully matured, just before they germinate.

Normally, mushrooms are harvested several times during the life of a mushroom, but if this voltage stimulation is applied only - times out of these times, the amount of mushrooms harvested will increase only when this stimulation is applied, but when harvesting other than this time. The amount may be reduced by the same amount as before or by the amount increased by stimulation, and the cultivation period will not be shortened.

Another important point of this invention is that this voltage stimulation is applied not only once, but every time, immediately before germination.

As a result, the amount of harvest increases each time, and the entire amount of mushrooms that Hodagi has is quickly exhausted, shortening the cultivation period.

In addition, if voltage stimulation is applied one by one, the amount of work and time needed to move a large number of hodawood would be enormous, making it nearly impossible to implement on a production line.

In the present invention, this problem is solved by placing hodagi vertically in a conventional water tank for immersion, as shown in Figure 3, and applying voltage stimulation to all the hodagi in the tank. are doing.

Next, a device for generating a steep voltage waveform will be explained with reference to FIG.

As shown in FIG. 2, a voltage regulator 1 adjusts an input voltage of 100V to Ov to 120V and outputs it to a transformer 2.

This transformer 2 boosts the voltage, but if the transformation ratio is 60, if you input 100V, it will be 6000V.If you need an even higher voltage, use a transformer with a larger transformation ratio, or
By connecting the 100v side in parallel and the 6000v side in series on the stand.

Can output twice the voltage.

This boosted AC voltage is converted into a DC voltage by a rectifier 3. Then, a DC voltage is stored in a capacitor 4, this charge is instantly discharged through an inductance, and this steep waveform voltage is applied to the hodagi 5 by a steep waveform voltage generator.

Next, referring to FIG. 3, a description will be given of a device for voltage stimulating a large amount of wood 5 at one time.

As shown in FIG. 3, a few inches of water 7 is poured into a container (water tank) 6 made of iron or concrete, and hodaki 5 are arranged vertically in parallel. In the case of an iron container 6, water is poured after covering it with an insulating sheet 8 to prevent creeping discharge. The water 7 also serves as a grounding electrode, and should be at least 2 to 3 inches from the bottom, at which point the water injection should be temporarily stopped. A conductive seal 10 is disposed below the electrode (wire mesh) 9 for applying voltage, and in order to apply voltage to all the hodagi 5 whose lengths vary slightly, the conductive seal 1o is used to The electrode 9 is brought into contact with the wood 5, and the electrode 9 is brought into contact with the conductive seal 10.
A voltage is applied between the water 7 and the water 7, and each hodaki 5 is stimulated with the voltage.

Next, based on the experimental data, a comparison example between stimulated Hodagi (test plot) and non-stimulated data (control plot) is shown in FIG.

A voltage with a wavefront length of 1 μs and a wavefront value of 10 kV was repeatedly applied 5 times to the test plot to 20 Hodagi that were inoculated in March, and the number and weight of the harvested shiitake mushrooms were calculated. This is a comparison with the control area.

Data are shown as Hodaki-Mori averages.

As can be seen in the comparative example in Figure 4, the experiment ended after four times, but the test plot harvested almost the entire potential mushroom capacity of the mushrooms in three times, and the control plot harvested the mushrooms the following month. is,
A shortening of the harvest period in the experimental plots has been observed.

In addition, when comparing the cumulative harvest up to November when all the harvest was completed in the test area, the number increased by 39% (63.6/45.6) and the weight increased by 35% (537.9/399.7). The effect is also cursed.

〔Effect of the invention〕

According to the present invention, by applying a voltage stimulus with a steep waveform to the mushroom cultivation method, almost the entire potential mushroom capacity of the mushrooms can be harvested in a short period of time, and chain failure due to bacterial detachment also occurs. The effect of increasing yield and shortening the harvest period becomes obvious.

Furthermore, since tens to hundreds of plants can be stimulated with voltage at the same time using a device that generates a steep voltage waveform, labor costs during harvesting can be reduced, resulting in a large economic effect.
