Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sapling used for cultivation of shiitake logs, a method for growing the sapwood, and a method for growing shiitake using the grown sapwood.

[0002]

2. Description of the Related Art Shiitake cultivation is roughly classified into a method of cultivating a log by inoculating Shiitake inoculum into a log, and a method of inoculating Shiitake inoculum into a medium mainly containing sawdust, which is then made of a synthetic resin bag or synthetic. There is a method for cultivating a fungus bed which is stored in a bottle made of resin or glass.

Raw trees such as kunugi and oak trees that have been cut down from autumn to early winter are left for an appropriate period of time to promote the evaporation of water, and after the living activity of the wood tissue is stopped, they are chopped into slices.
In the log cultivation method in which the obtained log is inoculated with sawdust inoculum or seed pieces in which mycelia are cultivated, a method of raising a sap tree in which the shiitake inoculum is quickly inoculated into the log by inoculating the log with the shiitake inoculum is 1 There are two important points.

[0004] Temporary prone (one of the operations of plunging) for raising such saplings is an important work which is said to account for about 80% of success or failure of sapling making. Most of them are performed under natural meteorological conditions, and the probation period varies depending on the tree species, cold and warm regions, location of the probation, etc., but it generally takes two months or longer.

[0005]

During the temporary probation period, if the proper environment is not maintained, such as maintaining humidity by spraying water on the logs after inoculation, suitable temperature conditions, and shading against sunlight, Occurrence of undesired harmful bacteria such as canker bacillus inhibits the survival and spread of Shiitake fungi, and eventually the yield of Shiitake is reduced.

[0006] For this reason, starting with the selection of a temporary storage place in a good environment for the cultivation of sapwood, adjusting the humidity by water sprinkling, work to avoid the effects of direct sunlight, and to keep the temperature constant A lot of troublesome work such as heat insulation work with vinyl is forced, and the loss of time and cost required for this work cannot be overlooked. Furthermore, this temporary probing occupies a large number of places for probation because the log inoculated with shiitake inoculum can only be horizontally stacked at a height of about 40 to 50 cm from the viewpoint of ease of work after the probing. It is a big bottleneck for shiitake log cultivation, because it requires a larger area for mass production.

In view of the current situation in the cultivation of shiitake logs, the present invention is a method for growing shiitake mushrooms and a method for growing shiitake mushrooms, which makes it possible to very easily and easily deoxidize the log inoculated with shiitake inoculum. Also, the present invention intends to provide a method for cultivating shiitake mushrooms using the cultivated logs.

[0008]

In order to achieve such an object, the invention described in claim 1 of the present invention is at least 1
Each of the holes has a waterproof package with a filter that blocks the invasion of various bacteria and ventilates, and the log is inoculated with shiitake inoculum, and the air is passed through the filter of the package. It is a cultivated shiitake cultivating bark which is characterized by cultivating shiitake inoculum and spreading hyphae.

Further, the invention according to claim 2 of the present invention is provided in a waterproof package having at least one through hole, and provided with a filter for preventing invasion of miscellaneous bacteria to vent through the through hole. After storing the raw wood inoculated with Shiitake inoculum, closing the mouth of the package and ensuring proper ventilation through the filter into the package, a large number of the raw trees stored in the package are laterally passed. It is a method for growing stalk trees for cultivation of shiitake mushrooms, which is characterized by stacking them in multiple stages, appropriately shading the upper part, and performing a bottoming operation to promote the survival of shiitake fungi and the spread of hyphae.

Further, the invention according to claim 5 of the present invention is provided in a waterproof package body which has at least one through hole and is provided with a filter for preventing invasion of miscellaneous bacteria to vent through the through hole. After storing the raw wood inoculated with Shiitake inoculum, closing the mouth of the package and ensuring proper ventilation through the filter into the package, a large number of the raw trees stored in the package are laterally passed. By stacking them in multiple stages and shading the upper part appropriately and performing a probing operation, it promotes the survival of Shiitake fungi and the spread of mycelium, and densifies the raw wood. It is a method for cultivating shiitake mushrooms, which is characterized in that the mushrooms are taken out from the plant and then the shiitake mushrooms are generated and grown by a conventional method.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, the raw wood to be used is a raw wood such as kunugi or oak that has been cut at a predetermined time, and left for an appropriate period to promote the evaporation of water and stop the living activity of the wood tissue. After making it, even if it is cut into a predetermined size (usually a length of about 90 cm),
Alternatively, it may be inoculated into a fresh raw tree after harvesting. In addition, it is preferable that the raw wood which has progressed to the dry state is appropriately sprinkled with water to moisturize the raw wood.

[0012] The seeds of Lentinus edodes may be inoculated into the above-mentioned logs either as sawdust seeds or seed pieces in which the fungi have been cultured in advance.

The raw wood inoculated with the Shiitake mushrooms is stored in a package, but the package used is not particularly limited as long as it is waterproof. Specifically, a bag of polyethylene, polypropylene, polyvinyl chloride, or the like can be used, and the size of the bag should be such that the inoculation log can be completely stored inside and the opening can be closed. The bag can be used without particular limitation, and the color of the bag is not particularly limited, but a black bag or a transparent bag through which the raw wood inside can be seen is preferably used.

This package has at least one through hole of a predetermined size, and a filter for preventing invasion of various bacteria and ventilating is provided in this through hole. The size and number of these holes should be such that the air necessary for the inoculation of the seeds and the spread of mycelium can be supplied to the logs stored in the package from the air-permeable filter attached to the holes. Is not particularly limited, but normally one having a diameter of 20 to 50 mmφ is 1
It is desirable to provide one or two.

The filter attached to the through-holes is a non-woven fabric in which synthetic fibers such as polyethylene fibers and polypropylene fibers are bound by a binder to provide air permeability, and a microporous film in which a polyolefin film is chemically porous. (For example, the product name "Juraguard" manufactured by Celanese Co., USA, the product name "Tyvek" manufactured by DuPont, USA, etc.) can be prevented from invading various bacteria, and aeration can be performed.

The through hole provided with such a filter is located near the end of the raw wood housed in the bag, for example, in the case of a slender bag, either on the side of the bag slightly away from the opening or on the bottom. Or it is formed in both parts. After the raw wood is stored in the package, the opening of the package is squeezed and tightly bound with a string or the like, or heat sealed to close the package.

It is most preferable to store one inoculation log in each package, but a plurality of inoculum logs may be stored in one package at the same time. It should be noted that if the number of stored pieces increases, problems such as damage to the package due to the weight of the stored raw wood are likely to occur, and handling at the time of temporary probation becomes troublesome.

[0018] When plowing the raw wood inoculated with the shiitake inoculum stored in this package (temporary probing), horizontal stacking,
There are various methods such as vertical enclosure and horizontal girder stacking, but horizontal stacking is preferable from the viewpoint of effective use of land and workability, and there is no special restriction on the stacking height, but from the standpoint of workability, the height is about 150c. Is preferred.

[0019]

The shiitake cultivating bark of the present invention has at least one through hole, and the shiitake inoculum is contained in a waterproof package provided with a breathable filter for preventing invasion of various bacteria in this through hole. The inoculated log is stored, the opening of the package is closed, and the filter is aerated through the filter in order to ventilate the inside log without the invasion of germs. It is possible to easily and easily disintegrate just by performing a down operation such as horizontal stacking.

Further, the method for growing the sapwood for shiitake cultivation obtained as described above is such that the raw wood inoculated with the shiitake inoculum is housed inside the opening of the package, and the opening of the package is closed to close the package. Through the filter formed in the above, the wood in the package can maintain an appropriate temperature and humidity simply by performing a sinking operation such as horizontal stacking while maintaining air permeability without invasion of germs. Incorporation work can be efficiently performed.

Furthermore, the method for cultivating shiitake mushrooms using the above-mentioned phosphatized hodoki enables the Shiitake inoculum inoculated into the log to be firmly attached to the log and the hyphae to spread, and The yield can be surely improved.

[0022]

EXAMPLES The following will specifically describe the shiitake cultivation sapling of the present invention, the method for growing the sapwood, and the shiitake cultivation method using the grown sapwood. The shiitake mushroom cultivars of this invention (hereinafter referred to as "hodaki") 1
Is a tree with a diameter of about 100 mm suitable for shiitake cultivation such as oak, kunugi, chestnut, chrysanthemum, oak, etc., cut into 900 to 1000 mm lengths as raw wood 2, and the raw wood 2 is perforated at predetermined intervals. It is the one that opens and drives the seed piece.

Thus, the raw wood 2 inoculated with the shiitake inoculum is stored in the packaging body 3 and used as the temporary storage raw wood 1. The wrapping body 3 is made of polyethylene and has a length of about 1300 mm and a width of about 400 mm. As shown in FIG.
Through hole 3a with a diameter of 30 mm on the side surface at a distance of 50 mm
And the same through hole 3b is formed at the bottom of the bag, and these through holes 3a
Polyethylene fibers are bonded to the portions 3 and 3b by a binder to prevent invasion of various bacteria and a non-woven fabric having an appropriate air permeability is attached to the filters 3a and 3b (for convenience, the through holes 3a
And 3b).

After storing one sapwood 1 in such a package 3, the opening 4 of the package is squeezed and tightly bound with a string, or heat sealed to close it, and the parts of the filters 3a and 3b. It is the one that is ventilated only from the inside. Although not shown, the filters 3a and 3b are
Any one of them may be formed. Log 2
When storing in the packaging body 3, it is preferable to lightly sprinkle the over-dried raw wood 2 before storing it in the packaging body 3 and then store it.

A large number of thus obtained hodagi 1 are temporarily laid down according to a conventional method, but this laying down operation may be carried out outdoors or in a greenhouse such as a vinyl house. Since moisturizing is generally the first consideration for temporary probation, a place where water can be sprinkled and where the wind is relatively weak and humidity is easily obtained is selected, but in the present invention, such conditions are preferable. However, it is not an absolute requirement.

Specifically, as shown in FIG.
It is stored in the package 3 on the sleepers 5 and 5 arranged on the ground, and the shards 1 are stacked side by side and the height is about 1.5 m.
After stacking so that
.. Place corrugated cardboard 6 on top to block direct sunlight. As a result, it is possible to aerate the inside of the package 3 through the filters 3a and 3b without causing miscellaneous bacteria, and to promote the engraftment of the Shiitake inoculum and the spread of mycelium.

At this time, when the time of inoculation is early and it is difficult to maintain a predetermined temperature, a synthetic resin sheet (not shown) is hung on the corrugated board 6 for keeping heat. On the other hand, if the temperature tends to rise too much, a covering material such as reed is placed on the uppermost stage to prevent an excessive temperature rise due to direct sunlight.

In this way, the block A of the series of sapwood 1 which has been temporarily suspended is observed for the inoculation state of the inoculum from the outside from time to time as the current state for a predetermined period of time, and transshipping and repositioning are performed as necessary. The suspension is completed as a sap tree that has been cultivated in a state in which all of the inoculation sites are uniformly germinated (about 60 days).

When each of the sardines 1 is taken out from the package 3 after the suspension, the spores on the mouth of the sardines 1 turn brown, which causes dry damage such as killed fungi, which are harmful bacteria in shiitake cultivation. Almost no germs are seen. Also, each Hodagi 1
There is almost no difference in the bacterium's survival state between the top 1 and the bottom 1 of the tree, and it is possible to see a generally uniform state of germination and survival.

After the temporary laying-down process is completed, the sardines 1 taken out from the package 3 are subjected to full laying-down according to a conventional cultivation method, and then shiitake mushrooms are generated and grown. That is, in cultivating fresh shiitake mushrooms, the saplings are submerged, then they are turned down, and then submerged to generate fruiting bodies by a sprouting operation. Also, when cultivating dry shiitake mushrooms,
Generates fruiting bodies in the natural environment. After that, the desired shiitake mushrooms are harvested through a predetermined process such as raising fruit bodies. Hereinafter, an example of shiitake cultivation according to the present invention,
This and a comparative example of shiitake cultivation by the conventional method under almost the same conditions are shown.

Example 1 Sliced oak (diameter of about 100 mm × length of about 900 m)
After inoculating each of the 20 pieces of m) with a seed piece, one piece of this one with a diameter of 30 mmφ is formed on the side surface near the opening of a polyethylene black bag of 400 mm width × 1300 mm length. A polyethylene non-woven fabric is adhered to the through hole and stored in a bag (packaging body) that has a filter that can ventilate without the invasion of various germs. I tied up. These are arranged side by side and piled up in multiple stages so that the height is about 1500 mm, and the top of the top sapwood is covered with corrugated cardboard to suspend it, and the growth of shiitake sapwood by the inoculation of inoculum and the initial spread of hyphae. Planned. After finishing the laying down, remove the sapwood from the bag and lay it down, then infiltrate it to generate and grow shiitake fruiting bodies, and investigate the state of harmful fungi at the end of the laying down and the fruiting body generation at harvest. .

Comparative Example 1 Raw logs inoculated with seed pieces were used as they were without storing them in a bag, and they were arranged side by side in a stack to have a height of about 1000 mm, and the top was covered with corrugated cardboard. I tried to raise the shiitake sapwood by suspending it. Otherwise, in the same manner as in Example 1, the shiitake fruiting body was generated and grown,
In the same manner, the generation state of harmful bacteria at the end of provisional probing, the number of occurrence of fruiting bodies and the weight per one were examined.

The specific conditions of Example 1 and Comparative Example 1 are as follows. 1) Logs Number of test specimens; 20 pieces each, oak sliced into 900 mm length Inoculation date: March 10, 1995 Inoculum: Seed piece (Mori No. 440) 2) Implantation temporary placement period; March 1995 May 10th to May 15th, 1995 Honboshi method: I laid it down on bare ground and applied Yoshis. 3) Occurrence of shiitake mushroom: It was submerged in water at a water temperature of 10 ° C for 12 hours on October 10, 1995. The test results of Example 1 and Comparative Example 1 are shown in Table 1. In addition, the number of surveys of the generation state of harmful bacteria in Table 1 is the number of duplicates.

INDUSTRIAL APPLICABILITY In the shiitake-cultivating sapwood of the present invention, raw wood inoculated with shiitake inoculum is stored in a waterproof package provided with a breathable filter for preventing invasion of various bacteria in the through hole. Since it is a dead tree, it is possible to perform the necessary disguising work on the shiitake log without needing to select a place for disguise or a special disguise work.

In addition, the method for growing sapwood for shiitake cultivation according to the present invention is a packaging body comprising a waterproof bag provided with a breathable filter for preventing invasion of various bacteria through a hole of a raw tree inoculated with seed bacteria. The filter is placed in a box and the opening is closed to ensure proper ventilation from the filter.A large number of these are piled up side by side and suspended while avoiding direct sunlight to establish the inoculation of the inoculum on the log and the initial inoculation of the inoculated inoculum. It is intended for the spread of. In addition, the method for cultivating shiitake mushrooms of the present invention is a method for cultivating shiitake mushrooms by a conventional method using a growing sap tree in which the inoculum obtained in this manner has been adsorbed on the raw wood and has been initially spread.

The method for growing sapwood for cultivating shiitake mushrooms and the method for cultivating shiitake mushrooms using the cultivated sapwood have many excellent effects described below. (1) After the raw wood inoculated with the inoculum is put in the package, the moisture in the raw wood keeps the inside of the package at a certain humidity, so there is no need to add water, and the sprinkling work after inoculation and the sprinkling facility used for it It is possible to expect labor saving and significant improvement in economic efficiency without the need for (2) Since the temperature inside the package is kept almost constant, the hyphae can be uniformly attached to all the inoculation sites, and the fungi can be spread evenly inside the log. (3) Since the raw wood is housed in a package and air is passed through the filter formed in the package without invasion of miscellaneous bacteria, the harmful fungi of shiitake cultivation do not invade from the outside and the shiitake caused by the harmful fungi. The loss is greatly reduced. (4) At the time of temporary sagging, since the post-inoculation log wood is put in a package in units of one to several, and is temporarily sagged, it is easy to interrupt the sagging work (drying of the log, adhesion of harmful bacteria, etc.). There is no need for troublesome steps such as sprinkling water every time the work is interrupted and applying a covering material unlike the case of the conventional temporary laying. (5) In the conventional temporary laying down, since the logs are normally stacked horizontally at a height of 400 to 500 mm, the number of accommodations per unit area is small (about 150 / tsubo), but in the present invention, it is 1500.
Since the sapwood can be horizontally stacked up to a height of about mm, the number of accommodations per unit area is greatly improved (about 400 / tsubo), and it is possible to easily lay down even in a narrow place. (6) In the conventional temporary probing, there was a large difference in temperature and humidity between the upper and lower shards, and variations and differences in slag formation were found. You can obtain Nahodaki, so there is no loss. (7) In addition, since it is certain that the Shiitake bacterium will be attached to the raw wood and the hypha will spread at the initial stage of the inoculation, the loss of the production of sapwood after that will be eliminated, and as a result, the yield of fruit bodies, which is the final purpose, will increase. And management is stable. (8) It is possible to effectively and easily grow saplings by applying them to raw logs in the state of raw trees whose water content is difficult to control, which has been increasing in recent years.
