Description

Detailed Description of the Invention (Field of Industrial Application) The present invention provides a shaped piece for inoculating mushrooms that easily and reliably inoculates logs with shiitake fungi in Shiitake mushroom cultivation and improves work performance. Regarding.

(Conventional technology) Conventionally, the seed fungi used for shiitake mushroom cultivation include wooden seed pieces made by cutting logs on which shiitake fungi have been cultured into a regular shape.
It is broadly divided into powdered sawdust bacteria cultured on sawdust, and gypsum bacteria cultured in a mixture of sawdust and gypsum. Although a wooden seed piece with cultured bacteria can be easily driven into a seed hole using an automatic seeding machine or by manual operation, this type of seed piece requires time and effort to manufacture.

(Problems to be solved by the invention) When the shiitake mushroom fungus is a sawdust fungus, the inoculum is a powder, so it takes time and effort to inject it into the inoculation hole of the log, making it difficult to handle. This method has the disadvantage that the inoculum in the inoculation hole must be covered to prevent it from drying out, resulting in extremely low work efficiency. However, this sawdust fungus is cheap and has the advantage that the fungus quickly attaches itself to logs, allowing the mushrooms to grow quickly.We have solved these drawbacks and taken advantage of the advantages to make it easier to inject the sawdust fungus. This is the basis for developing this shaping piece.

(Means for solving the problem) A mold formed in the shape of a seed piece that can be press-fitted into the inoculation hole is used, the mold is filled with sawdust bacteria or sawdust, and the upper surface of the mold is filled with sawdust bacteria or sawdust. This is a shaping piece for inoculation which is provided with a lid having a rod-shaped core that reaches to the lower end so that the core, the lid, and the inoculum are integrated.

(Function) A mold formed in the shape of a seed piece is filled with sawdust mixed with shiitake fungi, and a lid is placed on the top surface of the seed piece in the mold and the lid is allowed to adhere due to the growth of bacteria. Normally, it takes 5 to 10 days to remove the mold from the lid, but since the core of the present invention is located on the underside of the lid, the mold can be removed without waiting for bacteria to adhere. The lid and bacteria are firmly fixed in a short time due to the presence of the core. In addition, when only sawdust is used, gypsum is mixed as a binder and removed after molding, but in this case as well, the lid can be sufficiently maintained by the core. In this way, it is easy to fix the lid to the seed piece in either case, whether the lid is attached due to bacterial growth or not.

(Example) The embodiment of the shaping piece with a lid will be explained with reference to the attached drawings. The figure shows a mold (not shown) in which sawdust bacteria or gypsum bacteria are pressurized around the core body 5. It is formed by molding into the shape of a seed piece, and Figs. 1 and 2 have lids 1 on the top and bottom, and a third
The figure shows a case where the core body 5 is short and connected to the lid 1.

However, all of these shaping pieces are equipped with a lid 1 on the top, and especially in FIG. 1 of the present invention, when the core 5 reaches the bottom surface and is driven into the inoculation hole, the core retains its shape and the lid 1 blocks outside air to prevent drying and allow bacteria to take root, and the mycelium that is implanted into the log invades the tissue of the log, leading to the growth of shiitake mushrooms. Note that it is more effective to use a plurality of cores.

(Effects of the Invention) When seed pieces with lids are inoculated onto logs, drying is prevented, so the growth of bacteria is not inhibited, moisture is conserved, and rooting is ensured.

Conventional gypsum pieces have a weak structure and are easily damaged, and the length of the pieces tends to be too short, making it difficult to drive in satisfactorily, reducing the efficiency of inoculation work. In the gypsum piece having the core of this invention, the core reaches the lower end, so the height of the piece is constant, the structure is solid, it is difficult to break, it is easy to drive by hand, and the piece is not easily damaged. It is an extremely excellent and advanced technical invention that has the effect of significantly improving workability since it can drive both gypsum fungus and gypsum fungi in the same way as wooden seed pieces.
